According to the needs for optimal maintenance of equipment in the power plant

the condition monitoring and diagnosis system of vacuum circuit breaker is studied.The approaches to collect condition information and the items are presented based on the failure mode effects and criticality analysis of vacuum circuit breaker.A multi-level integrated and distributed system framework is proposed

and the hardware structure and software functions are discussed.The experimental results show that this system can serve as an advanced tool for the condition monitoring and fault diagnosis

enhance maintenance quality and efficiency

and reduce maintenance cost.
