The utility model relates to a mechanical program key electromagnetic control lock for high-voltage power transmission and distribution equipment. A lock core is installed in the lock body of the mechanical program key electromagnetic control lock, the program key is inserted into the lock core, and can drive the lock core to rotate, the front end of the lock core is pressed on the control key of the control switch, and a stopper is fixed on the side of the program key. There is a gap at the keyhole on the shell, and an arc-shaped groove is opened on the lock body. There is an electromagnet core in its electromagnetic attraction part, and the electromagnet core passes through the lock body to block the program key. on the stop pin. The utility model can realize the anti-misoperation between the circuit breaker and the isolating switch, and can realize the strengthened management of the mechanical program key.
Description
The utility model relates to a kind of Mechanically programm's key Electromagnetic Control lock that is used for the high pressure equipment for power transmission and distribution.
For protection equipment and personal safety, power department has " five is anti-" standard of the maloperation of preventing to high pressure equipment for power transmission and distribution regulation.Update along with power equipment, especially in integrated automation converting station, the changeover switch of the control line breaker of Shi Yonging is by miniaturization changeover switch or button control in the market, have directly by computer operation, in both cases, the Mechanically programm's gauge tap lock that originally uses just can't
Operation sequence between control line breaker and the isolating switch can not reach anti-error requirement, and in addition, Mechanically programm's key also can't behavior adjustment management.
The purpose of this utility model provide a kind of can be easily in the anti-misoperation that realizes under the plurality of devices environment between line breaker and the isolating switch, and Mechanically programm's key is realized Mechanically programm's key Electromagnetic Control lock of tighten management.
The technical solution of the utility model is: this Mechanically programm's key Electromagnetic Control lock comprises the electromagnetism adhesive parts that are installed in the housing, lock body and gauge tap, in the described lock body lock core is installed, the program key is inserted in the lock core, and can drive the lock core rotation, the lock core front end is pressed on the operating key of gauge tap, rotate the disconnection and the closure that can realize gauge tap by lock core, gauge tap is connected in series the secondary circuit into breaker mechanism in the use, side at the program key also is fixed with backing pin, corresponding with it, keyhole place on housing has breach, has arc-shaped slot simultaneously on lock body, and the program key of making can insert and rotate.In the described electromagnetism adhesive parts electromagnetic core is arranged, corresponding with it, a through hole coaxial with electromagnetic core is arranged on lock body, when electromagnetism adhesive parts are in power failure state, electromagnetic core passes lock body, block program backing pin on the key, get final product the rotation of limiting program key, electromagnetism adhesive parts are connected in series with the normally closed auxiliary contact of breaker mechanism in the use.In addition, also can have a unlock hole at lock body near electromagnetism adhesive parts place, be convenient in Installation and Debugging or when abnormal failure occurring, use special tool to back down electromagnetic core, the program key of making rotates arbitrarily.
The utility model has the advantages that, because in the use, the program key is switched on or switched off the secondary circuit of breaker mechanism by gauge tap, after having only insertion and rotation program key, line breaker just can carry out closing operation, and line breaker is during disjunction, and the program key can't be transferred to branch, the closing operation that carries out next step isolating switch, satisfied fool proof requirement, also realized tighten management simultaneously the program key.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, this Mechanically programm's key Electromagnetic Control lock comprises electromagnetism adhesive parts 2, lock body 3 and the gauge tap 4 that is installed in the housing 1, lock core 5 is installed in lock body, program key 6 is inserted in the lock core, and can drive the lock core rotation, lock core 5 front ends are pressed on the operating key of gauge tap 4, rotate the disconnection and the closure that can realize gauge tap by lock core.Side at program key 6 also is fixed with backing pin 7, and is corresponding with it, and the keyhole place on housing 1 has breach, has arc-shaped slot simultaneously on lock body 3, and the program key of making can insert and rotate.An electromagnetic core 8 is arranged in electromagnetism adhesive parts 2, corresponding with it, a through hole coaxial with electromagnetic core is arranged on lock body 3, when electromagnetism adhesive parts were in power failure state, electromagnetic core passed lock body.
In use, gauge tap 4 is gone into the secondary circuit of breaker mechanism by junction block 10 serial connections, electromagnetism adhesive parts 2 also are connected in series with the normally closed auxiliary contact of breaker mechanism by junction block 10, behind insertion and the rotation program key 6, by gauge tap 4 secondary circuit of breaker mechanism is connected, line breaker can carry out branch, closing operation.When line breaker is in closing position, electromagnetism adhesive parts 2 dead electricity, electromagnetic core 8 passes lock body, block the backing pin 7 on the program key 6, the program key of making can not be to the commentaries on classics of circling round, and this moment since program on the key backing pin and the breach on the housing stagger, the program key is blocked by housing, can't transfer to carry out next step operation; When line breaker was in the separating brake position, electromagnetism adhesive parts 2 got electric, and electromagnetic core 8 is made it highly be lower than lock body by adhesive, and 6 rotatable times original positions of program key and dial-out make gauge tap 4 be disconnected simultaneously like this, and line breaker can't carry out closing operation.
In addition, also have a unlock hole 9 at lock body 3 near the position of electromagnetism adhesive parts 2, be convenient in Installation and Debugging or when abnormal failure occurring, use special tool to back down electromagnetic core, the program key of making rotates arbitrarily.
