Description
Technical field
The invention belongs to power distribution field, be specifically related to a kind of power distribution cabinet valve interlock.
Background technology
The power distribution cabinet used in power supply or distribution to have prevent by mistake a point falsely close circuit breaker, prevent on-load deciliter isolating switch (or stab contact), prevent cutter with ground (or earth connection) power transmission, prevent charged conjunction earthing (or hanging earthing conductor), prevent " five prevent " functions such as mistakenly entering charged chamber, effectively prevent the generation of electric fault-operation accident.Current middle-placed switch cabinet exist circuit breaker shift out cabinet outer after valve can the problem of manual unlocking, this problem brings potential safety hazard to middle-placed switch cabinet running job.
Summary of the invention
The object of the invention is just to overcome above-mentioned deficiency, provides a kind of power distribution cabinet valve interlock.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of power distribution cabinet valve interlock comprises platform trap door support, hangs spring bracket, connecting rod, connecting rod rack, top board, joint, runner, connecting plate, turnover panel forms, turnover panel is arranged on platform trap door support, and connecting rod is arranged on connecting rod rack, and connecting rod arranges extension spring bracket, the end of connecting rod is connected to turnover panel, top board articulated linkage, connecting plate articulated linkage, the hinged top board of connecting plate, runner connects connecting plate, and joint connects runner.Turnover panel is arranged on power distribution cabinet breaker chamber, promotes top board and advances inward, top board drivening rod, promotes turnover panel and rotates around platform trap door support, circuit breaker shift out cabinet outer after valve can not the device of manual unlocking, eliminate the potential safety hazard of middle-placed switch cabinet operation.
Structure of the present invention is simple, easy to assembly, simple to operate, dependable performance, can eliminate the potential safety hazard because misoperation brings.
Accompanying drawing explanation
Fig. 1 is structural representation sketch of the present invention.
Embodiment
As shown in Figure 1, power distribution cabinet valve interlock of the present invention comprises platform trap door support 1, hangs spring bracket 2, connecting rod 3, connecting rod rack 4, top board 5, joint 6, runner 7, connecting plate 8, turnover panel 9 forms, turnover panel 9 is arranged on platform trap door support 1, and connecting rod 3 is arranged on connecting rod rack 4, connecting rod 3 is arranged and hangs spring bracket 2, the end of connecting rod 3 is connected to turnover panel 9, top board 5 articulated linkage 3, connecting plate 8 articulated linkage 3, the hinged top board 5 of connecting plate 8, runner 7 connects connecting plate 8, and joint 6 connects runner 7.Turnover panel 9 is arranged on power distribution cabinet breaker chamber, promotes top board 5 and advances inward, top board 5 drivening rod 3, promotes turnover panel 9 and rotates around platform trap door support 1.
In actual use, vacuum circuit-breaker moves to service position, and vacuum circuit-breaker side plate backs down runner 7, and runner 7 promotes connecting plate 8, connecting plate 8 drivening rod 3, and connecting rod 3 promotes turnover panel 9 and opens, and valve is opened, and now vacuum circuit-breaker can be moved to service position; Vacuum circuit-breaker shifts out outside cabinet by service position, and valve falls, and turnover panel 9 resets under extension spring bracket 2 acts on, and blocking valve must not move.
