Abstract :
In this paper, an approach for intelligent detection and fault diagnosis of vacuum circuit breakers is introduced, by which, the condition of a vacuum circuit breaker can be monitored on-line, and the detectable faults can be identified, located, displayed and saved for the use of analyzing their change tendencies. The main detecting principles and diagnostics are described. Both the hardware structure and software design are also presented.
