A method for repairing and replacing hydraulic disc spring operating mechanism of 500kv circuit breaker

Abstract

The invention discloses a maintenance and replacement method for a hydraulic disc spring operating mechanism of a 500kV circuit breaker, which belongs to the technical field of maintenance and replacement of substation equipment. Place the support block, the support plate and the inspection and replacement platform on the hydraulic trolley and push them to the bottom of the hydraulic disc spring operating mechanism; the hydraulic trolley is raised until the disk spring part of the hydraulic disc spring operating mechanism and the support module on the upper part of the inspection and replacement platform contact; the telescopic module is extended to stably support the energy storage part of the hydraulic disc spring operating mechanism; remove the fixing bolts, rotate and remove the hydraulic disc spring operating mechanism; push the hydraulic trolley out of the maintenance station, and use the packing tape to The hydraulic disc spring operating mechanism is fixed on the maintenance and replacement platform, and the multiple support legs on the maintenance and replacement platform are screwed down to contact the support plate to lock the maintenance and replacement platform; use another hydraulic cart or forklift to remove the support plate , The overhaul and replacement platform and the hydraulic disc spring operating mechanism are handed over and transported as a whole. The invention saves manpower and material resources, and has high maintenance and replacement efficiency.

Description

technical field [0001] The invention relates to the technical field of maintenance and replacement of substation equipment, in particular to a maintenance and replacement method for a hydraulic disc spring operating mechanism of a 500kV circuit breaker. Background technique [0002] With the development of electric power in our country, substations are indispensable, and hydraulic disc spring circuit breaker equipment is widely used. When operating and repairing a large number of hydraulic disc spring mechanism circuit breakers, frequent suppression of the mechanism is common in such institutions. The defect will seriously affect the normal operation of the circuit breaker. When there is a fault in the mechanism and the mechanism needs to be replaced, because the mechanism is heavy and the working space is small, the bracelet hoist needs to be replaced manually, but this method consumes a lot of manpower and material resources, and the operation time is long. and low securit...

Problems solved by technology

[0003] Disadvantages of the existing method for replacing the hydraulic disc spring operating mechanism of 500kV circuit breaker: the current disassembly method needs to determine and make the binding point of the chain hoist according to the characteristics of the field equipment, because the circuit breaker manufacturers equipped with the hydraulic spring operating mechanism on site are different , construction forms, etc. are different, and the lengths of slings required to make binding points are different.

However, this utility model still adopts the suspension method to replace the hydraulic disc spring mechanism, and there are still problems of laborious and low efficiency for the heavy 500kV circuit breaker hydraulic disc spring operating mechanism
