Abstract
The invention discloses an emergency unlocking device of a ground switch interlock of a high-voltage switch cabinet. The emergency unlocking device comprises a back door of a cabinet body and the ground switch, wherein an interlocking piece is connected to the back door of the cabinet body, and a lock head is connected to the operating shaft of the ground switch. The interlocking piece comprises an interlocking piece main plate (1) and an interlocking piece lateral plate (2), a long kidney shaped hole (4) corresponding to the lock head is formed in the interlocking piece main plate (1), and two mounting hole (3) are formed in the interlocking piece lateral plate. By adopting the technical scheme, the emergency unlocking device provided by the invention has a simple structure, once the ground switch interlock is stuck and can not be unlocked, as long as a bolt is loosened, the interlocking piece can be opened from the outside of the cabinet body, and meanwhile, screwed connection is adopted, so that the disassembly is convenient.
Description
Technical field
The present invention relates to a kind of high-tension switch cabinet earthed switch interlocking emergency unlocking device.
Background technology
At present, in the electric power system, behind high-tension switch cabinet earthed switch and the high-tension switch cabinet during gate interlock, can only divide incompatible release by earthed switch, when high-tension switch cabinet keeps in repair or maintains, in case occur that interlocking blocks or can cause when other fortuitous events occurring the interlocking can't release, can not keep in repair or maintain thereby directly cause the back door to open.
Summary of the invention
Problem to be solved by this invention is at the deficiencies in the prior art, to provide a kind of high-tension switch cabinet wall bushing mounting structure that changes the sleeve pipe installing hole simple in structure, convenient.
To achieve these goals, the technical scheme taked of the present invention is:
This high-tension switch cabinet earthed switch interlocking emergency unlocking device provided by the present invention, comprise cabinet back door and earthed switch, described cabinet is connected with locking part on the back door, be connected with tapered end on the earthed switch operating axis, described locking part comprises locking part mainboard and locking part side plate, be provided with the long lumbar hole corresponding with tapered end at described locking part mainboard, be provided with two installing holes at the locking part side plate.
Described locking part side plate is connected on the cabinet back door by bolt.
Distance between described two installing holes is 30 millimeters.
Adopt technique scheme, this high-tension switch cabinet earthed switch interlocking emergency unlocking device provided by the present invention, simple in structure, in the time of can't release in case occur that earthed switch interlocking blocks, mainly unclamping bolt just can open locking part from the cabinet outside, adopt screw to connect convenient disassembly simultaneously.
