Problems solved by technology

This problem is mainly manifested in the S8 and S9 micro switch nodes in the chassis are damaged or the wiring is loose and the contact is not good, etc., requiring maintenance personnel to rush to the scene to deal with it
[0007] (2) Interlocking bending plate fracture
If the interlock lever bends and cannot return to shape after multiple locking actions, it will cause the circuit breaker to be swung in or out after closing, which seriously violates the requirements of the "Electrical Safety Work Regulations": the disconnector cannot be opened and closed with load
The result of misoperation will cause equipment d

Description

technical field [0001] The invention relates to electric power maintenance equipment, in particular to circuit breaker chassis maintenance equipment. Background technique [0002] The circuit breaker chassis is an important part of the circuit breaker. The chassis and the central cabinet body are insulated and coordinated, and mechanically interlocked, safe, reliable and flexible. The chassis has an isolated maintenance position and a working position in the cabinet, and each position is equipped with a positioning device to ensure reliable interlocking, and must be operated according to the interlocking anti-misoperation procedure. The chassis adopts nuts and screw rods to shake and advance and withdraw, which is easy to operate. Once the chassis fails, it will affect the normal operation of the switchgear, and in severe cases, it will cause a power outage on a certain line. [0003] In order to enhance the reliability of power supply, it is required that the power failu...
