Analysis and Handling of a 110 kV GIS Circuit Breaker Body Failure to Open and Close Normally
GIS circuit breakers mainly consist of the circuit breaker body,operating mechanism,and transmission link. The operating mechanism is connected to the circuit breaker body through the transmission link.Once the transmission link falls off or deforms,it will directly affect the normal opening and closing operation of the circuit breaker.This article conducts on-site inspection and cause analysis on a 110 kV GIS circuit breaker transmission link shaft pin that fell off,cau-sing the circuit breaker body to be unable to open and close normally.Corresponding improvement measures are proposed based on this fault.
