摘　　要：利用故障树分析方法分析两重冗余结构停堆断路器的四种连接形式的停堆动作误动和拒动故障,并充分考虑了拒动故障对停堆动作的影响。结果说明:停堆断路器二选一结构类型Ⅰ连接形式的拒动率和可靠度指标优于其他三种类型的;通过敏感度分析,给出停堆断路器拒动的改善措施应侧重于停堆驱动信号拒动率的减小的建议。Using fault tree analysis method to analyze dual redundant shutdown circuit breaker of four various connection shutdown circuit breaker in the form of action misoperation and refusing action failure,and give full consideration to the effects of refusing action failure to shut down the action.Results show that:shutdown circuit breaker a choice typeΙconnection structure form of refusing action rate and the reliability index is better than the other three types.Through the sensitivity analysis,the improvement measures of the shutdown circuit breaker should focus on the reduction of the shutdown drive signal rejection rate.
