摘 要: 本文在应用Markov过程对变电主接线进行可靠性评估的过程中,对其中的主要元件断路器进行了专门讨论,深入阐述了断路器在运行中可能出现的各种故障,并运用Markov过程的基本理论,对其经故障统计得出的原始状态空间图按正常、拒动、其它扩大型故障(除拒动外)和非扩大型故障进行状态合并、得到能全面反映断路器各种故障模式的可靠性等效模型。 All kinds of possible failures of breakers are discussed deeply in this paper, during the process of evaluating reliability of the electrical main wiring. Original state space diagram of the breaker's failures is combined according to it's four states—normality, refusing action, other expanding failures and non expanding failures using the basic Markov Processes Theory. A full and exact equivalent model of the breakers is obtained . Analysis of a practicall sample is given to detail it at the end.
