Reliability Estimation of Vacuum Circuit Breaker Based on Maximum Likelihood Estimation

The life test of the vacuum circuit breaker with permanent magnet actuator is carried out for the reliability estimation. The failure situation and the mechanical characteristic parameters during the test of the vacuum circuit breaker are recorded. The Weibull distribution is used to analyze the reliability test data of vacuum circuit breakers. According to the maximum likelihood estimation theory of Weibull distribution in the case of time-censored experiments, the experimental data are iteratively calculated. The reliability evaluation model of vacuum circuit breaker is obtained, and the reliability of vacuum circuit breaker with permanent magnet actuator is quantitatively analyzed.
