摘要

断路器在供配电系统中起着重要的控制和保护作用。断路器的可靠性直接影响到电力系统的稳定运行。永磁作动器结构简单，可控性强，是真空断路器在控制开关和调速中应用的理想操动机构。为了研究永磁执行机构真空断路器的可靠性，采用故障模式与影响分析(FMEA)和故障树分析(FTA)的方法对真空断路器的故障进行了分析。本文根据真空断路器的结构模型，对真空断路器的FMEA分析结果和FTA分析模型进行了讨论，有助于提高真空断路器的可靠性。

Failure Analysis of Vacuum Circuit Breaker with Permanent Magnet Actuator

The circuit breaker plays an important role of control and protection in the power supply and distribution system. The reliability of the circuit breaker directly affects the stability of the power system. Because of the simple structure and strong controllability, permanent magnet actuator is an ideal operating mechanism for the vacuum circuit breaker to apply in the controlled switching and the speed regulation. To investigate the reliability of vacuum circuit breakers with permanent magnet actuator (PMA), the fault of vacuum circuit breaker is analyzed by the method of Failure Mode and Effects Analysis (FMEA) and Fault Tree Analysis (FTA). According to the structural model of the vacuum circuit breaker, the FMEA analysis results and the FTA analysis model of the vacuum circuit breaker are discussed in this paper, which are helpful to improve the reliability of the vacuum circuit breaker.
