Abstract
The utility model discloses a front-door interlocking device with a maintenance channel switch cabinet. An interlocking shaft (4) is fixed on a middle side plate (5) between a cabinet lower door (10) and a maintenance channel door (1); the lower door (10) is provided with a push plate (9); the maintenance door is provided with a fastening plate (2); two ends of the interlocking shaft are respectively provided with a fastening crank arm (3) and a push plate crank arm (8); and the interlocking shaft is provided with three pins (7), and the side plate is also internally provided with a torsion spring (6). According to the front-door interlocking device, the manufacture is simple and easy, the installation is convenient, the operation is simple, the interlocking is reliable, and the requirement of power workers for the safety of power transmission and distribution equipment can be met.
Description
Technical field
A kind of maintenance cabinet door interlock of the utility model electrical power distribution system band access path switch cubicle.
Background technology
At present; The work about electric power personnel have proposed very high requirement to the fail safe of equipment for power transmission and distribution in the power transmission and distribution system; Particularly switch cubicle is definitely can not open the Qianmen under charged situation, and this cabinet door interlock is exactly a kind of interlock newly developed in this case.
This interlock is suitable for the switch cubicle that has access path, and this interlock has guaranteed that the staff must close access path earlier according to the operating sequence operation of switch cubicle, closes the Xiamen again; Divide the ground knife switch, close circuit breaker and send electricity, when does not open the Xiamen; Repair door and can not open door and can not open, divide earlier circuit breaker during sub-switching operation, has opened the Xiamen; The access path door just can be opened, and so just can prevent staff's mistakenly entering charged chamber, causes the accident of human electric shock.
The utility model content
The purpose of the utility model is exactly to design a kind of access door interlock of simple type.
This practical interlock is a fixing chain axle 4 on the latus inframedium 5 between cabinet Xiamen 10 and the access path door 1; Push pedal 9 is housed on the Xiamen 10; Buckle 2 is housed on the access door; Chain axle two ends are respectively snapping connecting lever 3 and push pedal connecting lever 8, on the chain axle three pins 7 are arranged, and wherein in side plate, also have torsion spring 6.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure: 1, access path door 2, buckle 3, snapping connecting lever 4, chain axle 5, latus inframedium 6, torsion spring 7, pin 8, push pedal connecting lever 9, push pedal 10, Xiamen
Shown in accompanying drawing; This practical interlock is a fixing chain axle 4 on the latus inframedium 5 between Xiamen 10 and the access path door 1; Push pedal 9 is housed on the Xiamen 10, buckle 2 is housed on the access door, chain axle two ends are respectively snapping connecting lever 3 and push pedal connecting lever 8; On the chain axle three pins 7 are arranged, wherein in side plate, also have jump ring 6.
The cabinet door interlock that the utility model provides; Close access path door 1, close Xiamen 10 afterwards, push pedal 9 promotes push pedal connecting lever 8 in the time of the pass; Snapping connecting lever 3 under the drive of chain axle 4; After the Xiamen was closed fully, the buckle 2 complete snappings on snapping connecting lever 3 and the access path door 1 made the access path door not open; When opening the door, open Xiamen 10, and push pedal 9 is come out, and chain axle returns under the effect of torsion spring 6, makes snapping connecting lever 3 open, and makes access path door 1 be able to open.
The cabinet door interlock that the utility model provides is made simple and easy, easy for installation, simple to operate, and interlocking is reliable, can satisfy the requirement of work about electric power personnel to the equipment for power transmission and distribution fail safe.
