Description
Technical field
The utility model relates to electrical equipment, espespecially a kind of low voltage switchgear safe lock mechanism.。
Background technology
Existing switchgear is at two-way electric power incoming line: a road is killer switch inlet wire, one tunnel is isolating switch inlet wire, two-way power supply only allows a road electric power incoming line, when killer switch one road electric power incoming line works, another road isolating switch power inlet wire must first disconnect, and after guaranteeing the position that isolating switch is in " dividing ", killer switch electric power incoming line switch just can be made to close a floodgate power, because isolating switch can only utilize operating grip to carry out separating brake or closing operation, cannot to realize electrically chain with disconnect, when killer switch inlet wire works, because closing isolating switch by mistake, and the accident causing two-way power supply to be powered occurs simultaneously.For avoiding the generation of the accident, being necessary to improve associated mechanisms, guaranteeing that isolating switch can not have misoperation to occur.
Utility model content
The purpose of this utility model is to provide a kind of low voltage switchgear safe lock mechanism, is intended to solve the problem that there is the potential hazard of misoperation in prior art.
The utility model realizes like this, a kind of low voltage switchgear safe lock mechanism, comprise the operating grip be arranged on switchgear cabinet door, described operating grip is connected with isolating switch by rotation axis, and killer switch, described operating grip be fixedly connected with one can coaxial rotating motion interlocking disk, described cabinet door inner surface is provided with a fixed head, described fixed head is fixedly connected with electromagnet, described electromagnet is electrically connected with described killer switch, described electromagnet has after an energising can outwardly directed axle, described cabinet door is provided with hole and passes for described axle, described interlocking disk has a through hole or breach and can hold the axle that described electromagnet stretches out under electrical condition, when described shaft extension goes out to insert described through hole or breach, described isolating switch is closed condition, described operating grip is in separation point position.
Preferably, described interlocking disk is fixedly connected with the center back position of described operating grip by hold-down screw.
Preferably, the base of described operating grip is fixedly connected with described cabinet door by trip bolt, and described fixed head is also fixedly connected with described cabinet door inner surface by described trip bolt.
Preferably, described fixed head is L-shaped, and described fixed head lower end plane is hung by screw and installs described electromagnet.
Use technique scheme, one end of described rotation axis is connected with operating grip, and its other end is connected with the operating mechanism of isolating switch, by operating grip rotated by rotation axle rotation and to be reached point, close the object of isolating switch by operating mechanism.Interlocking disk is fixed together by hold-down screw and operating grip, and rotates with operating grip.The base of operating grip and the fixed head of fixed electromagnet are together fixed on cabinet door by trip bolt.The power supply of electromagnet is attracted by killer switch incoming line cabinet, when being energized to electromagnet, the axle of electromagnet stretches out forward, and extend in the hole of interlocking disk, interlocking disk is lockable formation locking, also be lockable cannot rotate with the operating grip that be connected of interlocking disk, also just cannot to carry out point, conjunction isolator operation; When electromagnet power-off, its axle then moves backward and replys position, and interlocking disk unlocks, and can rotate with operating grip, carry out isolating switch point, closing operation.When killer switch one road electric power incoming line needs work, first give electromagnet power-off, allow the axle of electromagnet move backward and reply position, interlocking disk is unlocked, operating grip is utilized to drive rotation axis to rotate disjunction isolating switch together, operating grip is made to be on the position of " dividing ", meanwhile, be energized to electromagnet again, the axle of electromagnet is stretched out forward, and extend in the hole of interlocking disk, interlocking disk is lockable formation locking, the operating grip be connected with interlocking disk is also lockable and cannot rotates, the operating grip of isolating switch is locked on the position of " dividing ", guarantee isolating switch separating brake time, killer switch one road electric power incoming line just can carry out combined floodgate and power.Otherwise, when needing the electric power incoming line work of isolating switch one road, first breaking circuit breaker switch, make killer switch electric power incoming line one road power cut-off, meanwhile, to electromagnet power-off, allow the axle of electromagnet move backward and reply position, interlocking disk is unlocked, utilizes operating grip to drive rotation axis to rotate together and isolating switch is closed a floodgate.When electromagnet does not have an electricity, the axle of electromagnet moves backward and replys position, and interlocking disk is unlocked, and to be carried out point, closing operation by operating grip to isolating switch; When electromagnet has an electricity, the axle of electromagnet stretches out forward, and extend in the hole of interlocking disk, interlocking disk is lockable formation locking, the operating grip be connected with interlocking disk is also lockable and cannot rotates, also just cannot to carry out point, to close isolator operation, solve technical problem of the prior art, stopped the generation of peril.
Beneficial effect: switchgear two-way electric power incoming line a: road is killer switch inlet wire, one tunnel is isolating switch inlet wire, two-way power supply only allows a road electric power incoming line, when killer switch one road electric power incoming line works, another road isolating switch power inlet wire must first disconnect, and after guaranteeing that isolating switch is in open position, killer switch electric power incoming line switch just can be made to close a floodgate and power, the accident avoiding two-way power supply to power occurs simultaneously.Because isolating switch can only utilize operating grip to carry out separating brake or closing operation, cannot to realize electrically chain with disconnect, be ensure safe power supply, with anti-misconnection isolating switch, isolating switch increases safe lock mechanism, the operating grip of isolating switch is locked on open position.When the power-off of killer switch inlet wire separating brake, when requiring the power supply of isolating switch inlet wire combined floodgate, safe lock mechanism unlocking, utilizes operating grip to carry out separating brake or closing operation to isolating switch.Have this safe lock mechanism, isolating switch can not have misoperation to occur, and ensure that the normal of power supply.
