Abstract
The utility model discloses an electromagnetic drive type locking device for movable doors of a switch chamber of a high-voltage switchgear. The electromagnetic drive type locking device comprises a cylindrical housing and fixing mounting bolts, and is characterized in that an electromagnetic coil is disposed in the cylindrical housing, the front end of the electromagnetic coil is provided with a locking column, the inner end of the locking column is wound with a reset spring, a connecting terminal of one leading-out lead of the electromagnetic coil is provided with a wiring clamp connected with an operating position normally closed contact A in a bus room, a connecting terminal of the other leading-out lead of the electromagnetic coil is provided with a wiring clamp connected with a handcart maintenance position normally closed contact C, and the locking column is corresponding to a lock sleeve port installed on the movable door. According to the electromagnetic drive type locking device for the movable doors of the switch chamber of the high-voltage switchgear, self-locking of the movable door of the high-voltage switchgear can be achieved, the electromagnetic drive type blocking device is simple in structure and low in manufacturing cost, when a handcart switch is pulled out, the movable doors of the high-voltage switchgear at the bus side and the outlet side can be automatically locked, and accidental injury accidents caused by the fact that maintainers open the movable doors due to misoperation in an operating time can be effectively prevented.
Description
Technical field
The utility model relates to the improvement of a kind of high-tension switch cabinet switch gear room valve locking, after specifically a kind of wheelbarrow switch pull-out, high-tension switch cabinet switch gear room valve electromagnetic drive type locking device that can automatic blocking to the upper and lower valve of bus bar side and outgoing line side high-tension switch cabinet switch gear room.Be mainly used in the service work of 10kV, 35kV cubicle switch cabinet.
Background technology
Along with the continuous propelling of power grid construction, switch cabinet of converting station quantity is increasing, and in the cabinet of switch cubicle, maintenance progressively becomes one of groundwork of substation equipment maintenance and repair personnel.In switch cubicle, be provided with high-voltage switch gear, vacuum circuit breaker summation current transformer, vacuum circuit-breaker is arranged on handcart, and in handcart utilization, 3 phases, 6 moving contacts of lower 3 phases are pegged graft with 6 fixed contacts corresponding in cabinet, realize circuit and connect.The annexation of bus is as following table in its wheelbarrow switch and cabinet:
It can be seen from the table,, if bus bar side is not charged, 3 contact switch A, B, C are all failure to actuate, in normally off; If in the situation that bus bar side is charged, in the time that needs overhaul, handcart is pulled open, even pull out outside cabinet, then carry out maintenance in cabinet, now wheelbarrow switch A, B are all failure to actuate, and in normally off, and wheelbarrow switch C opens, and disconnects the electrical connection of handcart band.The deficiency of this maintenance is: due to narrow space in cabinet, maintainer and charged high voltage bus fixed contact close together easily cause personnel to touch charging equipment by mistake in maintenance process; , because the insulating barrier at charged position is not locked, still may open by the bindiny mechanism of insulating barrier dodge gate meanwhile, if there is malfunction in the course of work, just may open valve, cause the generation of major accident.At present, in the time that wheelbarrow switch pull-out is overhauled, valve is used manual folding conventionally, therefore has huge potential safety hazard.
In order to overcome above the deficiencies in the prior art, known by retrieving, there is at present multiple high-tension switch cabinet accidental opening preventative locking, but be mechanical driving structure, its complex structure, cost of manufacture are high.Have not yet to see after wheelbarrow switch pull-out, can automatic blocking and electromagnetic drive type locking device simple in structure to bus bar side and the upper and lower valve of outgoing line side high-tension switch cabinet.
Summary of the invention
The purpose of this utility model is to provide one not only can realize the self-locking of high-tension switch cabinet valve, and its complex structure, cost of manufacture are low, when after wheelbarrow switch pull-out, high-tension switch cabinet switch gear room valve electromagnetic drive type locking device that can automatic blocking to bus bar side and outgoing line side high-tension switch cabinet valve.
In order to reach above object, the technical scheme that the utility model adopts is: this high-tension switch cabinet switch gear room valve electromagnetic drive type locking device, comprise cylindrical case and fixed installation bolt, fixed installation bolt is located at four bights of the square floor of cylindrical case, it is characterized in that: in described cylindrical case, be provided with solenoid, front end at solenoid is provided with lock, lock stretches out from the prosopyle of cylindrical case, the inner of lock is wound around back-moving spring, a link of drawing wire of solenoid is provided with the binding clip being connected with the service position normally closed contact A in switch gear room, the link that another root of solenoid is drawn wire is provided with the binding clip being connected with handcart maintenance position normally closed contact C, described lock is corresponding with the mouth that is arranged on the lock tube on dodge gate.
The beneficial effects of the utility model are: this high-tension switch cabinet switch gear room valve electromagnetic drive type locking device, not only can realize the self-locking of high-tension switch cabinet valve, and simple in structure, cost of manufacture is low, when after wheelbarrow switch pull-out, can automatic blocking to bus bar side and outgoing line side high-tension switch cabinet valve, the generation of effectively having avoided maintainer to open valve, accidental injury accident in operating time internal cause misoperation.
Brief description of the drawings
Fig. 1 is that structure master of the present utility model cuts open schematic diagram depending on office.
In figure: 1, cylindrical case; 2, fixed installation bolt; 3, square floor; 4, solenoid; 5, lock; 6, back-moving spring; 7, draw wire; 8, the binding clip being connected with the service position normally closed contact A in bus-bar room; 9, the binding clip being connected with handcart maintenance position normally closed contact C; 10, lock tube.
Embodiment
Make the utility model with reference to Fig. 1.This high-tension switch cabinet switch gear room valve electromagnetic drive type locking device, comprise cylindrical case 1 and fixed installation bolt 2, fixed installation bolt 2 is located at four bights of the square floor 3 of cylindrical case 1, cylindrical case 1 is fixed on the wall of high-tension switch cabinet switch gear room insulating barrier by fixed installation bolt 2, it is characterized in that: in described cylindrical case 1, be provided with solenoid 4, be provided with lock 5 at the front end of solenoid 4, lock 5 stretches out from the prosopyle of cylindrical case 1, the inner of lock 5 is wound around back-moving spring 6, a link of drawing wire 7 of solenoid 4 is provided with the binding clip 8 being connected with the service position normally closed contact A in bus-bar room, the link that another root of solenoid 4 is drawn wire 7 is provided with the binding clip 9 being connected with handcart maintenance position normally closed contact C, described lock 5 be arranged on the mouthful corresponding of lock tube 10 on dodge gate, when wheelbarrow switch C in off position under, solenoid 4 is charged, attraction lock 5, lock 5 does not insert in lock tube 10, in the time of maintenance, pull open handcart, make wheelbarrow switch C in maintenance position, now, solenoid 4 is opened power-off because of wheelbarrow switch C, lock 5 loses its reliss, under the effect of back-moving spring 6, insert in lock tube 10, valve is pinned, like this, within the operating time, can not open valve because of misoperation with regard to having ensured.
