It states the first card slot with the handle hole of earthing switch to be connected, first baffle is rotatably arranged in the cabinet, first push plate
It is fixed in the cabinet door, the first baffle is inserted into first card slot when the cabinet door is opened, when the cabinet
The first baffle produces under the action of the first push plate from the first card slot when door is closed.
In above structure, when cabinet door in the open state, first baffle be inserted into the first card slot in, by the behaviour of earthing switch
It is blocked as hole, so that operation handle can not carry out separating brake in insertion operation hole to earthing switch so that locate always in cabinet
In uncharged state, the danger for preventing operating personnel from getting an electric shock in operation.After cabinet door is closed, it is fixedly connected on cabinet door
On the first push plate driving first baffle produced from the first card slot so that first baffle, which loses, blocks handle hole, at this time
Can operation handle insertion operation hole be subjected to sub-switching operation to earthing switch.
Further, the second interlock assembly, second interlocking are additionally provided between the earthing switch and the cabinet door
Component includes second baffle and the second card slot, and the second baffle is fixed on the earthing switch, second card slot
It is fixed in the cabinet door, when the grounding switch tripping, the second baffle is inserted into second card slot to cabinet door shape
Into limiting, the second baffle loses from the second card slot transfer second baffle of sening as an envoy to when the earthing switch closes a floodgate
Limiting to cabinet door.
In above structure, when grounding switch tripping, it is fixed on the second baffle on earthing switch and is inserted into the second card slot,
It matches to form cabinet door with the second card slot and limit so that cabinet door can not be opened；After earthing switch combined floodgate, it is fixed on ground connection
Second baffle on switch leaves the range of the second card slot with the rotation of handle hole, loses the limiting to cabinet door so that cabinet
Door can be opened.
Further, the first baffle includes insertion end and linkage end, is provided between the insertion end and linkage end
First rotating shaft, first push plate and the position of the linkage end in contact are provided with inclined-plane.
In above structure, the insertion end of first baffle may be inserted into the first card slot and handle hole blocked, and cabinet door is being closed
After closing, the inclined-plane in the first push plate is contradicted on the linkage end of first baffle so that and the linkage end of first baffle rotates down, from
And the insertion end of first baffle is caused to leave the first card slot upwards.
Further, the second card slot section is C fonts, and the side that second card slot has opening is fixedly connected on institute
It states in cabinet door, opposite side cooperatively forms the limiting to cabinet door with the second baffle.
In above structure, when second baffle is inserted into the second card slot, cabinet door is when opening, second baffle and the second card slot
It is inconsistent so that cabinet door can not be opened.
