- I - 基于 Bootstrap 法及性能退化的永磁机构可靠性分析 Reliability Analysis of Permanent Magnetic Actuator Based on Bootstrap Method and Performance Degradation
Abstract As a kind of switching device, the reliability of the circuit breaker directly affects the stability of power system. The operating mechanism occupies an important position in the circuit breaker, so its reliability is attracting more and more attention. Using bi-stable permanent magnetic actuator in vacuum circuit breaker as the research object, this paper develops its reliability research from the lifetime and performance degradation, and establishes its reliability distribution model from the parameters which can characterize its reliability, providing reference for the reliability evaluation of permanent magnetic actuato
