Problems solved by technology

At present, the method of opening and operating the insulating baffle is to use the insulating rod to directly push up or press down the isolation baffle. This method firstly has a huge problem in the process of pushing up or down the baffle due to the unreliable support of the insulating rod. The possibility of resetting the baffle, the second is that when the baffle mechanism is slightly jammed, the upward or downward force of the insulating rod cannot be reversely satisfied to overcome the resistance of the mechanism jamming, so that the isolation baffle cannot be operated, and even if you continue to use force, it will Causes damage to the isolation baffle and the mechanism; if the transmission mechanism is directly operated manually, since the transmission mechanism is close to the static contact, even if you wear insulating gloves, you cannot guarantee the electrical safety distance of 0.7 meters between the person and the live contact when the baffle is opened.

Abstract

The invention discloses an adjustable multipurpose switch cabinet contact baffle auxiliary support frame, and the frame comprises a support frame main body which comprises a first support plate, a second support plate connected to one side of the first support plate in a sliding manner, and a transverse sliding part arranged at one end, far away from the second support plate, of the first supportplate; and a locking assembly which is arranged between the first supporting plate and the second supporting plate, the second supporting plate of the device and the sliding part at the front end of the device can be adjusted, the purpose that the baffle can be opened for 10kV switch cabinets which are manufactured by different manufacturers and have different sizes is achieved, the labor is saved, the safety distance is met, and the practicability is high. The problems that an isolation baffle is inconvenient to open and the safety distance is insufficient in operations of phase checking, electricity testing, grounding wire installation and the like on an upper static contact and a lower static contact in a circuit breaker chamber at the present stage are solved.

Description

technical field [0001] The invention relates to the technical field of switch cabinet circuit breakers, in particular to an adjustable multi-purpose switch cabinet contact baffle auxiliary support frame. Background technique [0002] At present, when performing operations such as phase verification, electrical inspection, and installation of grounding wires for the upper and lower static contacts in the switchgear circuit breaker room, it is necessary to open the front isolation baffle for the upper and lower static contacts in the switchgear circuit breaker room, and the baffle The up and down opening of the upper and lower baffles requires the operation of lifting and pressing the transmission mechanism part of the upper and lower baffles. At present, the method of opening and operating the insulating baffle is to use the insulating rod to directly push up or press down the isolation baffle. In this method, there are huge problems in the process of pushing up or down the b...
