On-Line Monitoring Parameters Selection of Circuit-Breakers' Operation Mechanism
the mechanical failure was the main part of circuit-breakers defects,based on the fault probability distribu-tion of circuit-breakers' operation mechanism,also considering the field convenience and cost,on thought of the auxiliary part,vibration and pressure and etc.,the cost-efficient on-line mon itoring parameters and method of circuit breakers' operation mechanism are discussed in detail in this paper.
