Description
Technical field
The utility model relates to a kind of switchboard, and more particularly, it relates to a kind of emergency unlocking mechanism of high-tension switch cabinet.
Background technology
High-tension switch cabinet refers to for power system generating, transmission of electricity, distribution, electric energy conversion and plays the effects such as break-make, control or protection in consuming, and high-tension switch cabinet is by making the electric equipment products of electric pressure at 3.6kV ~ 550kV.
High-tension switch cabinet is generally divided into four rooms, and what be wherein positioned at bottom is cable vault, and is provided with earthing line device for power in cable vault, arranges interlock 7 between this earthing line device for power and door-plate of cable vault.As shown in Figure 4, holding section 31 on locking plate 3 is engaged in the groove 21 on locking bar 2, then key and lockhole 71 double-linked cam (being arranged in the inwall of Electric Appliance Cabinet) is utilized, locking bar 2 is upwards driven, make the holding section 31 on locking plate 3, enter into the Access Division 22 on locking bar 2, just achieve the locking function of door-plate and cable vault; After realizing locking, only have when earthing line device for power is in "on" position, just locking bar is driven to move down by key and lockhole, make disengaging Access Division, holding section enter into groove to unlock, so that door-plate is opened, otherwise after key insertion lockhole, cannot rotate that (interlock is locked by lockhole, cannot rotate after causing key to insert lockhole), namely cannot unlock, therefore operating personnel can obtain safety guarantee.But when certain electric device in earthing line device for power goes wrong, when causing earthing line device for power to open, and then also can cause the door-plate of cable vault lock cannot be untied so that door-plate can not be opened, so if the cable encountered in cable vault breaks down, when needing emergency maintenance, some extreme modes (e.g., being damaged by lock body) door-plate can only be utilized to open, then keep in repair.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of when ground path switch exists fault, the emergency unlocking mechanism of the high-tension switch cabinet also can opened by door-plate smoothly.
For achieving the above object, the utility model provides following technical scheme: a kind of emergency unlocking mechanism of high-tension switch cabinet, comprise door-plate and locking bar, locking bar is fixedly connected with on the inwall of cable vault, also include the trip lever that locking bar can be pulled to move up and down, door-plate offers the unblock window extending into inside, cable vault for trip lever.
Preferably, the end of trip lever is provided with engaging post, locking bar offers the connecting hole for the engaging of engaging post.
Preferably, also include against post, be fixedly installed on the inside wall of cable vault against post and be positioned at the side of the corresponding door-plate of locking bar.
Preferably, door-plate is provided with for blocking the shielding plate unlocking window, shielding plate can be arranged along the Plane Rotation of door-plate.
Compared with prior art, the utility model has the advantages that: in the technical program, when earthing line device for power breaks down, only need to utilize trip lever to extend into the inside of cable vault by unlocking window, engaging post is made to be engaged in connecting hole, then locking bar is pulled to move down, make the Access Division on the holding section disengaging locking bar on locking plate, enter into groove effectively to unlock, this process both handled easilies, also can not opposite house body or interlock causes damage, improve usability of the present utility model.
