摘　　要：针对磁感应式自动过分相系统在动车组运用过程中多次引发跳主断问题,分析过分相系统自检延时设置原理,结合国内高铁主干线接触网分相区设置等数据提出优化措施,大幅降低故障率,为动车组正常运营时序性提供了保障。With regard to the problems of main circuit breaker tripping when the EMU is passing through automatically the magnetic inductive type phase break,the paper analyzes the principles on setting of self-inspection time delay for automatic phase breaking,with connection to the data for setting of OCS neutral section for high speed railway trunk line in China,by which the fault rates are greatly reduced,providing a guarantee to the normal operation timeliness of EMU.
