断路器机械特性的监测和故障诊断

Mechanic Characteristics Monitoring and Fault Diagnosis of Circuit Breaker

介绍了断路器的基本结构,提出了反映其机械特性的基本参数。总结了基于各种传感器的参数监测手段和相应的故障诊断方法。通过对这些参数的监测并实现诊断,为断路器实现从定期维修向状态检修打下了良好的基础。

Circuit breaker＇s basic structure was introduced. Parameters which indicated its mechanical characteristics were put forward. Monitoring methods based on kinds of sensors and fault diagonisis methods were summarised. Foundation for realizing transition from regular overhauling to condition overhauling of circuit breaker is laid by implementing the parameters monitoring and fault diagnosis.
