4. Device and principle of the switch operation.

Switches VK-10 belong to liquid three-pole high-voltage switches with a small volume of the exhausting fluid (transformer oil). They are intended for switching high-voltage chains of three-phase ACs in the nominal mode of the electrical installation, as well as to automatically turn off these chains with short circuits and overloads arising from emergency modes.
The principle of operation of the switch is based on an electric arc, which occurs when the contacts are blurred, the flow of a gas oil mixture formed as a result of the intensive decomposition of transformer oil by the action of high arc temperature.
This stream receives a specific direction in a special exhausting device, placed in the burning zone of the arc.
The control of the VK-10 switch is remotely or in manual is made by the motor spring drive of indirect action. The switching on the switch is carried out due to the energy pre-stapped by turning the drive springs. Turning off the switch is carried out due to the energy that the disconnecting spring switch when turned on.
The base of the switch (Fig. 1) consists of a frame 1 on which installed side racks 7 For fastening the drive 5 and the pedal 9 is fixed to unlock the switch in the CR RC cell, the grounding contact 2 and the body of the pole mechanism 3.

The housing of the pole mechanism is made by a monoblock for all three poles.
Inside the case on each pole, there is a mechanism for moving a moving rod, consisting of two levers: outer 11 and inner 13, rigidly fixed on the total shaft 10. The mechanism shaft is installed on the sliding bearings and has seals with protective washers.
The outer levers 11 of the shaft of the pole mechanism associated with the overall burden 12 is connected to the disconnecting spring 17 and the adjustable burden 15 with the arm of the switch drive 18.
The pole of the switch consists of an insulating cylinder 13, at the lower end of which the metal flange 8 is evaluated. The cylinders are fixed on the body 6 of the mechanism.

The inner lever 13 (Fig. 1) of the Pole Mechanism Insulating 9 is hingedly connected to a movable rod 4 (Ø 24 mm for switches for nominal currents 630, 1000 A and Ø 28 mm - on nominal currents 1250, 1600 A). To increase resistance to the action of an electric arc and an increase in service life upper end The movable rod is equipped with a contact, lined with an arc-resistant metal ceramics.
In the cylinder of the pole installed a current collector, consisting of a rope 10 with two guide rods 2.

A conductor 3 is installed between guide and moving rods 3 (roller collecting device), which serves to transmit current from movable on guide rods and simultaneously to direct movable rods. The conductor has from four to eight steam of the rollers depending on the rated current of the switch off.

Fig. 2 Camera is a dug-making.

Over the current collecting device on the spacer cylinder 11 installed an extinguishing chamber 12 of the transverse oil blast. The exhausting chamber consists of a package of insulating partitions, pulled by three studs. The upper partition of the chamber has a replaceable ring 1 (Fig. 2) from a dug-resistant material, which, with strong burning, can be replaced without changing the partition. The camera has a central hole for the passage of the movable rod. In the upper part of the chamber, the insulating partitions form three transverse, located one above the other, blowing gaps 2 for obtaining large currents associated with a through vertical channel 3 with subcarrine and superchard spaces. At the bottom of the chamber there are two deaf oil pockets 5 to clean the small currents. Cone plug 4 installed in the middle part of the chamber prevents the movable rod from excessive acceleration under the action high pressurearising from the disconnection of short circuit currents.

The camera is installed on the camera 14. Based on 8 (Fig. 3 and 4) of contact in the cable 7 installed nine lamellas 6 for switches for nominal currents 630, 1000a and eleven - for switches on nominal currents 1250 and 1600a, the lower ends of which are lined with an arc-resistant Metal ceramics. From the outside, each lamel has a nest, where spring 5 is installed, resting in the cylinder 4. The lamellas of the lower internal ends are pressed to the pusher 3. The pusher protects the silver contact surfaces of the lamellas from the burning; At the same time, the pusher serves as a damper when turned on. Above the pusher is installed spring 2. At the base, the valve 14 is set (Fig. 3) with an oil inlet hole, which is closed with a ball 1 to prevent the emission of a gas oil mixture when disconnected. The base 8 is connected by a pipe 10 with a lid 12 (Fig. 3, in the switches to nominal currents 630, 1000a) and with a casing (in the switches on the nominal currents 1250, 1600a). In the lid and in the casing there are holes for filling the oil, gas outlet and glass installation of 1 oil indicator. The oil designer serves to observe the oil level in the pole and consists of a glass of oil indicator with two piece risks and located in the pipe 10 float 9 (Fig. 3) with the oil indicator rod.

The pole of the switch to nominal currents 1250 and 1600 and differs from the pole on the rated currents 630 and 1000 and the presence in the upper part of the metal ribbed casing and the performance of the base 8 (Fig. 4) of the socket contact as one with a current-carrying rod.

5. Spring drive device.

A constructive feature and advantage of the drive is to use the excess energy of moving parts for the partial subset of the drive springs at the end of the switch on the switch.
The drive consists of the following main parts: the frame, the main parts of which are the front wall, the middle wall 27, the rear wall 37, the side chastellers 34 and the upper channel 48; shaft 41 crank with ratchet wheel 43; Shaft 1 of the drive articulated with the switcher shaft; primary shaft 6; free discharge mechanism 70; electric motor 52 with gearbox; shaft manual factory 51; Springs of inclusion 74; an additional springs of inclusion 62; contact block (QSM) 58 drive positions; contact block (q) switch positions (switches 42 and 79); terminal clamps (HT) 11; buffer 63; blocking latch 22; Electromagnet remote disconnection (YAT) 85; electromagnet of remote disconnection of independent power (YAV) 80; remote switching electromagnet (yac) 18; Relay lock from reclosing (KBS) 36; Manual turning buttons 10 and manual shutdown 86; Inclusion latches 15; Installation of wiring 84; block 93 relay current electromagnets; Counter of the number of operations (SAB) and block - lock.
The inclusion mechanism, the operating positions of which are shown in Fig. 4, consists of: lever 2 with a needle bearing mounted on a primary shaft 1, shaft 3 crank, mechanism of free discharge 6, lever 7, the lever of the plant 8, springs 5 \u200b\u200band shaft 4 drives. The mechanism is used for: holding the drive and, respectively, the switch shaft in the on position; switching off the switch when exposed to the mechanism of the disconnecting element (the position "A" or "B"); Transmission of the efforts of the workshop of the disconnecting springs from the primary shaft to the drive shaft and, respectively, to the switch shaft during the power process (from the position "A" in "C").
Clockworking device of operation springs 74, 62 consists of an electric motor 52 with a gearbox; installed on its eccentric dog shaft 46, spring-loaded spring 53; ratchet wheel 43; shaft 41 crank; The lever 76 and the lever of the plant 69.
Buffer top walls attached to the wall 27, and low part - on the primary shaft 6. The buffer is intended for: Restriction of the angle of rotation of the lever 72 when the switch is turned on; partial absorption of energy and mitigating the moving parts of the drive when turned on; Locking (hold) shaft 1 of the drive and, accordingly, the switch in the on-line position through the lever 72 and the mechanism of free discharge 70.
The blocking latch 22 is designed to lock the inclusion 15 latch when the switch position is turned on and the driving springs are turned on. The inclusion lock device is shown in Fig. 7. When the lever 2 is turned off, the drive shaft 1 is pressed by its protrusion spring-loaded spring 4 blocking latch 3 and unlocks the axis 5 of the inclusion latch 9.
The anti-discharge device ensures the following locking functions (crucial): the impossibility of increasing the switch from the disassembled (control) position in the working; The inability to enable the switch on the switch in the intermediate position between the separated and workers. The principle of operation of the anti-precipitated device is based on the effects of pedal 9 (Fig. 1) of the base on the rod of the anti-precipitated device when the switch is rolled out of the disassembled position in the working or when rolling out of the worker in disunity. When you press the pedal and exposure to it on the latter 13, moving up and acting with my fingers 11, turns the lever 1, which is connected to the cam 2 and, turning it (clockwise), locks the fists 17 of the comprising device.
To calculate the number of inclusion operations - shutdown (B) in the drive, the counter of the number of operations. To block the turning device at the head of the working springs of the drive, the block is installed in it. It ensures that it is impossible to turn on the switch when the lock is inserted into the block and rotate the key. Installing the meter and block - lock is shown on.

Fig. 12. Installation of the gap between the teeth of the dog and the ratchet wheel

The block - the lock works as follows: turning the key 16 counterclockwise fist 9, turning, raises the lever 7, which its groove fixes the turning fist 17 (Fig. 12). At the same time, the cams 9, acting on the microswitch 12, breaks the power supply power supply circuit (YAC) 18 and the power supply circuit of the lock relay from reclosing (KBS) 36. This reaches the mechanical and electrical locking of the switch in the disconnected position; To turn on the switch, it is necessary to rotate the key 16 clockwise to unlock the activation device of the drive, and the sequence of the elements of the block - the reverse lock is described above; When the switch is turned on, the lever 10 under the action of the spring 3 is rotated counterclockwise, and the rod 13 locks the fists 9, which does not allow to rotate the inserted key 16, and therefore, block the drive and, respectively, the switch is in the on-line position.

6. Drive operation.

The drive in the disconnected position with the incompleted work springs of inclusion 74 and 62. For the automatic springs factory, it is necessary to supply power to the electric motor 52 with a gearbox. The vibrational movement of the dogs 43 reports the rotational movement of the ratchet wheel 43, which is rigidly planted on the shaft 41 crank, which turns the levers 59 and 69 clockwise, rigidly connected to the primary shaft 6, and starts work springs, while the spring 62 is compressed, and Spring 74 is stretched.
To prevent the rating of the ratchet wheel under the action of the effort that occurs in the process of breeding work springs, in addition to the brake (view A), a locking dog is provided 30. The process of folding the free-length mechanism 70 occurs throughout the operation of the work springs and ends at the end of the factory, and When the springs are installed - instantly.
The springs factory can be manually by rotating the springs plant handle clockwise. When the handle is rotated, the dog movement is driven 45, installed on the crank end of the shaft of the hand-made factory 51. In the future, the movement of the drive parts occur in the same sequence as when driving the working springs by the gearbox. At the end of the planting springs, the knob of the plant rotates at idle, since the dog 45 is in contact with the ratchet sector 43, on which there is no teeth.
With not fully headed work, the springs cannot be turned on the switch remotely. The manual switching lever is possible to enable and disable the switch when applied and measure the moment on the shaft of the pole mechanisms.

7. Preparation of the switch to the commissioning

Preparation of the VK-10 switch to work must begin with an outdoor inspection, while checking the condition and reliability of fixing all nodes and parts. If necessary, tighten the fasteners and restore the lubricant on rubbing surfaces, especially turning attention to the presence of lubrication in the hinged joints of the lever 69, the lever 72 of the free extension mechanism 70, rollers 21 and 88 of the inclusion switch 15, on the working surfaces of the guide 68.
Remove the conservation lubrication. The circuit breaker contacts have a galvanic coating, so the stripping of their surfaces with a file or emery skurt is unacceptable. When cleaning, it is necessary to use the solvent, for example, BR - 1 or alcohol gasoline. Contact surfaces of current-hand rods in the touch zone with lamellas of sticky contacts cover with a thin lubricant layer.
Check the operation of the oil buffer, for which it is to press the rod of the piston down to the stop, then let go sharply; In this case, the piston must quickly, without jamming, return to its original position.
Unscrew the plugs of the oilpill and drain the oil from the poles.
Check the maximum and minimum retaining moments on the shaft of the pole mechanisms in accordance with section 8.
Make the oil plugs and pour the poles along the top level of oil transformer oil. To do this, set the switch to the disconnected position, unscrew the glass of the oil indicators and slowly pour the oil before the start of the float movement. Install the glasses of oil indicators and add oil to the top level through the whipping hole in the lid 12 (Fig. 3). Pure dry oil before filling in the poles should have a punching voltage of at least 25 kV in the standard discharge.
Check the speed of shutdown and inclusion, the electrical resistance of poles in accordance with section 8.
Check the serviceability of blocking devices and switch mechanisms in accordance with section 8.
Watch switch. The wiping material must be clean and not to leave a pile. Insulating cylinders wipe the rag, slightly moistened with alcohol, White spirit or BR - 1 gasoline.

8. Measurement of parameters, adjustment and configuration.

Measuring parameters and adjustment of the VK-10 switch is made when preparing it to work or after full and partial disassembly and assembly of poles or drive.
In the process of adjusting the switching switch and shut off, only manually controls the manual switching lever.
The switch drive is recommended to be adjusted during the assembly process in such a sequence:
1. The tension of the springs 74 (Fig. 5) is regulated by screws 26 so that the gaps between the springs and channel 34 are: for the upper spring - 3 mm, for the bottom - 10 mm.
2. Guaranteed gap between the dental of the dog 45 or 1 (Fig. 12), located in the extreme position, and the tooth of the ratchet wheel 2 with the full gear of the dog's tooth 3 with this wheel during operation should be 0.5 ± 0.20.1 mm. . To obtain this gap, you must perform the following operations: Install the manual switching lever and when the switch is turned off, turn the lever clockwise until it stops, while the drive springs are incomplete; In the additional holes of the channel 48 (Fig. 5) insert two adjusting screws M 8x20; weaken the screws 49; adjusting screws to put a gap; Unscrew the screws 49 alternately, install between the 47 holder 48 of the washers 50; screw the screws 49, pre-lubricating their threaded part by a sealing composition of DN - 2; Remove adjusting screws M 8x20.

Check the total move of the movable rod, which must be 160-4 mm; If necessary, it is regulated by changing the number of washers installed under the oil buffer 15 (Fig. 1).
Check the tension of the disconnecting spring 21 (Fig. 1, view C). The clearance between the end of the disconnecting spring and the focus of the frame should be (28 ± 12) mm.
It will set the gap 0.5 ... 1 mm between the lever of the pole mechanism and bolt 22 (Fig. 1).
The maximum inclusive moment on the shaft mechanisms of the poles of the switch is measured using the manual switching lever 3 (Fig. 14), fixed on the shaft, as shown in the figure, and the cargo set in the following order:

2. Rotating the lever counterclockwise, tested the rods to touch them with socket contacts.
3. To hang on the lever load of this value so that it creates a moment with the lever 235 N * M for switches to nominal currents 630 and 1000 A or 255 N * M for switches to nominal currents 1250 and 1600a.
4. The goods are free, when driving under its own weight, it should turn on the switch to the full position (before landing the latch drive).
Maximum comprising moment on the shaft of the switch of the switch of the switch is measured using a dynamometer; At the same time, the lever at the time of the contact of the contacts should occupy a position close to the vertical (Fig.14).
If the moment is greater than the specified values, it is necessary to check the quality of the assembly of the poles (increased friction, running), the presence of lubrication in the mechanisms of mechanisms, correctly installing the disconnecting spring.
The minimum retention moment on the shaft of the power of the switch of the switch when the switch is checked on the stroke of the movable rods in the socket contacts using the manual switching lever 3, fixed on the shaft according to Fig. 14, and the set of goods in the following order:
1. Install the switch to the disconnected position (the drive is not started).
2. Rotating lever counterclockwise, turn on the switch before landing the drive on the latch.
3. To hang on the lever cargo of this magnitude so that it creates a 40 N * m with the lever.
4. Holding for the lever, press the shutdown button. When the lever is released, the switch must be disconnected to the full exit of movable rods from the socket contacts.
It is allowed to measure the minimum retaining torque when disabled using a dynamometer; In this case, the lever when the switch is turned on must occupy the position close to the vertical (Fig. 14).
If the moment is less than the specified values, it is necessary to check the tension of the disconnecting springs.

Fig. 17. Sector for measuring speeds.

The speed of movable rods when turning on and disconnecting the switch is measured by the electromagnetic vibration and sector (Fig. 17). To measure the speeds, fasten the tight paper 30 mm wide on the sector, set the sector to the shaft of the pole mechanisms, securing it with a bolt M 8 x 10 with a washer. Turn the drive springs. With the help of a vibration, write three vibrograms on and shutdown. An example of determining the velocities by the vibrogram is shown in Figure 18.

Fig. 18. Determination of the speeds of the vibrogram.
I - switch disabled; II - switch included; III - inclusion; IV - shutdown.

If the speeds do not correspond to the norm, it is necessary to check the switching of the switch, as well as the absence of pushing the moving elements and the presence of lubrication on rubbing surfaces, or change the tension of the disconnecting spring 21 (Fig. 1), varying the size of 28 mm within ± 12 mm.
The speed of movement of movable rods must be consistent with the data of Table # 2.

Verification of blocking devices:
1. Conduct workers from the working springs of the drive handle handle or by means of an electric motor with a gearbox. Make sure that with a complete factory, when switching the shaft 41 (Fig. 5), the crank through a dead point, the planting dogs 45 and 46 came out of the engagement with the ratchet wheel 43, the power supply circuit is torn to the SQM block.
2. Check the impossibility of turning on the drive when the switch is turned on and the fully installed work springs, as well as when the switch is turned off and not fully under the drive when exposed to the manual switching button or from the control key.
3. Check the operation of the charming device of the driving springs. When you click on the pedal in the disconnected position of the switch, the lever 2 (Fig. 5) must lock the switching cam 17 before the eccentric will report the movement of the lever 81.
4. Check the operation of the block - lock. When inserted into the block - lock and rotated counterclockwise, the key should not be manual (from the button) or remote (from the electromagnet) switching on the switch. When the switch is enabled, it is not possible to insert and rotate the key block - lock.
5. Check the operation of the free-length mechanism when the switch is turned off, for which you should put on the primary drive shaft of the manual switching lever, start the spring drive, turn the lever counterclockwise to the angle "20 ° and submit a command to shut down.
The switch must turn off. Then repeat the check by turning the lever at 40, 60 and 80 °. The switch must be disconnected from any position.
6. Check the operation of the electrical lock (block relay) "against jumped", for which it is necessary to start the involving drive springs when the switch is turned on. Then simultaneously submit voltage: for a long time on the electromagnet of inclusion and briefly on the shutdown electromagnet. In this case, the re-turning on the switch should not occur.

9. Maintenance of the switch.

When operating the switch, it is necessary to ensure that the operating voltages and the load current are not exceeded the normalized values.
Monitor the oil level in the poles that should not be lowered below the lower line of the oil indicator.
Due to the fact that the oil serves to quench an arc and only partially isolates the phase break, it can be used in the blackened form. Oil should be replaced if it has a punching power below 15 square meters.
During operation, a switch, current and capital repairs should be inspected.

Inspection of the switch Must be done at least once a month. When viewing the switch, you must perform such checks.:
1. Conduct the external inspection of the switch and verify the absence of contamination of its outer parts, especially insulating parts;
2. Ensure no cracks on insulating parts;
3. Ensure that there is no ejection of oil and traces of leaks through seals in the poles
4. Check the oil level in the poles;
5. Make an external inspection of contact compounds and make sure there are no signs of excessive heating of supply tires.

Current renovation switch Must be held annually. For current repairs The following works must be carried out:
1) merge the oil, remove the filling contact. Remove the exaggecious chamber, check their condition, as well as the state of socket contacts and movable contact rods. If the opening contacts and cameras have a non-essential wear, then it suffices to clean these surfaces with a file or shallow sandpaper, then rinse with transformer oil.
2) Pour the switch with clean transformer oil and make sure that there are no leaks through seals.
3) Check the oil buffer operation by pressing the rod.
4) Clean the bolted joints, check the reliability of fastening the supporting insulators, the switter frame, the ground strip.
5) Make a rubbing of porcelain insulators and insulating levers. Lubricate contact connections with lubricant. If necessary, restore lubrication of rubbing parts.
6) Check the switch adjustment, moments. Measure the transitional resistance of the poles. The speed of movement of moving contacts at the time of turning on and off the switch.
7) Perform measurement resistance of the insulation of the primary and secondary chain.
8) Cleaning, lubricant of rubber parts, minor drive repair.
9) Check the operation of the switch with the switching on and disconnecting it from the control panel (remote) and on that.
10) Registration of documentation.

Overhaul of the switch Must be carried out once every 6 - 8 years, as well as when the switch 3000 "B" cycles - "O" is performed, after performing the total turning on and disconnecting the nominal shutdown current of 12 ka - 18 operations or 20 ka - 10 operations, or 31.5 ka - 7 operations. With overhaul, it is necessary to make the following work:
1) Disconnect the supply tires from the switch and drain the oil.
2) Perform a complete disassembly of the switch (except drive).
3) produce a wipe of porcelain insulators and insulating levers. Clear all the details from the old lubricant and other contaminants.
4) Check all hinge connections both in a switch and remote transmission, restore them to normal (replace), lubricate.
5) Check and, if necessary, replace the fasteners.
6) Rinse all internal cylinder cavities with transformer oil.
7) repair moving contact rods.
8) Pour the transformer oil switch, make sure that there are no leaks from the poles and, if necessary, tighten the bolt connections.
9) Conduct the necessary measurements of transition resistance, speed characteristics, torque. If necessary, adjust the switch and remote transmission.

" When conducting overhaul The switch is recorded in the repair card for repair and measured characteristics are recorded in the repair card (Appendix No. 1) - all lines of the card are filled.
If the measured switch characteristics are inconsistent at the current repairs, the standards specified in the application table number 1, the switch must be output to extraordinary overhaul.

10. Security measures when operating the switch.

The service switches must know their device and the principle of operation, must be familiar with this instruction and strictly follow its requirements.
The switch of the switch must be securely connected by the grounding contact 2 Figure 1 with the core case.
The front metal septum of the switch must have a reliable electrical connection with the frame (base).
When examining the switch in the operating position in CR, it should be remembered that the poles of the switch are under high voltage, so it is forbidden to penetrate any objects into the zone located behind the facade metal partition.
Adjustment and repair of the switch is made only in the absence of voltage on both pole conclusions, in the secondary switching circuits and with non-unchecked drive springs. The drive springs should never start to install the drive on the switch and articulation with the pole mechanisms, since the drive mechanisms with the junior springs are very dangerous.
The lever for manual inoperative switching on the switches cannot be left on the actuator or pole.
Measurement of the moment on the shaft of the switch is made only with the driven springs of the drive.
The operational inclusion and switching off of the switch should be performed only remotely.

Operating Instructions for the Malyaslial Switch CE-10
General Instructions for Operating Switch

Switches are designed to work in the following conditions:
 height above sea level no more than 1000m;
 ambient temperature from -25 ° C to + 45 ° C with heating;
 relative air humidity not more than 80% at a temperature of + 20 ° C;
The environment explosive and fireproof, dust and gases can not exceed the norms for the type of atmosphere II according to GOST 15150-69.
The operating position of the switch is vertical.
During operation, it is necessary to monitor the oil level in the poles, which should not be descended for the lower label on the oil indicator.
All information about turning off short circuits, about the faults detected during the operation of the switch, as well as the results of periodic inspections are entered by duty PS staff to the automatic shutdown log and operational magazine, respectively.
Turning off the current switch K.Z. followed by unsuccessful APF is considered as a trip of 3 k.z.
The principle of operation of the switches is based on the arc gash arising from the opening of contacts, the flow of a gas-oil mixture, which is generated as a result of intensive decomposition of transformer oil. This stream receives a specific direction in a special exhausting device placed in the zone of the arc burning area (exaggeted camera).
The control switch of the WCE-10M is made by electromagnetic drive.
 The switching on the switch is carried out due to the traction force of the inclusion electromagnet.
 Turning off the switch is carried out due to the energy stored for the disconnecting spring switch when turned on.
The switch consists of:
 frame that is attached to a tipping trolley;
 three poles, each of which is fixed to the frame with two insulators having internal elastic fittings;
 drive electromagnetic;
 Fiberglass insulating thrust, which transmit movement from the drive through the switch shaft to the mechanism of moving movable pole contacts.

The inclusion mechanism serves to transfer torque from the primary shaft (developed power of the power electromagnet core) on the output shaft of the drive and on the switch shaft during the power process; retention of the output shaft of the drive and the switch of the switch in the on position; Turning off the switch when exposed to a lever of the disconnect device into the lever of the free-length mechanism.
All other elements of the switch have the same device and destination, as at the VK-10 switch.
The switching on the switch occurs when power is applied to the inclusion electromagnet coil, the electrical data is shown in Table. eleven.
At the end of the inclusion process, the output shaft of the drive acts as a cam to the auxiliary contacts of shutdown, turns off the power electromagnet power supply circuit. When the switch is turned on, the auxiliary contacts of the switch position associated with the drive output shaft are switched. The position of the switch is recorded by a buffer device.
Turning off the switch occurs when the power is applied to the shut-off electromagnet coil or press the shutdown button. Disconnected switch position and drive. Fixed with a buffer device. In the drive window appears the inscription.
Electrical data of shutdown coils are shown in Table. 12.
Table 12.

Plock contacts of shutdown and power on, the auxiliary circuit breaker contacts are mounted on a shared bracket. Blocking contacts of shutdown and power on switched to each cam, which are rigidly fixed on the shaft connected to the drive shaft by means of adjustable thrust. The switching circuit on and disconnecting the drive is charged through blocking contacts, which ensures automatic stopping power to and disconnecting the electromagnet after the corresponding operations. They also achieves preparation for subsequent operations. Plocking power contact opens the inclusion circuit at the very end of the switch on the switching on, and the locking contact of the shutdown opens the trip circuit to the opening of the main contacts of the switch, thereby freeing the contacts of the relay from incisioning the turning electromagnet arc.
The speed of movement of the movable rods of the CE-M-10 switch is given in Table. 13.
The electrical resistance of the conductor of each pole between the upper and lower conclusions without socket contacts at the switch to the current 630 A is 50 (40) MCOM; per 1000 A - 45 (40) MCOM; at 1600 a - 25 μC. In brackets are the data for the switches by 31.5 to A.
The Malomal CE-M-10 switch is an upgraded CE-10 switch, which has been manufactured until 1990.
The CE-10 switch was distinguished from the CE-M-10 design of an electromagnetic drive, which has another envelope in height and its total From the base of the switch is 627 mm instead of 443 mm (see Fig. 12). The electromagnetic drive of the WCT-10 switch consists of a stove, casing, a mechanism with a disconnecting electromagnet, rows of clamps, auxiliary contacts for control circuits and blocking, including coils. In the lower part of the drive base, rubber gaskets that serve as a buffer of the core falling after the inclusion process is completed.
