摘要
自动转换开关(Automatic transfer switching equipment)简称ATSE,是电源系统中配电箱或开关电源内部一个没有冗余保护的机械结构节点,有可能导致电源供电中断,降低或解决ATSE故障成为电源系统维护工作的重要课题,提出一种铁路通信高频开关电源进行技术改造方案,解决ATSE和蓄电池同时故障导致直流供电中断的问题。
Automatic transfer switching equipment(ATSE)is a mechanical structure node without redundancy protection in distribution box or switching power supply of power supply system.It’s fault is very likely to cause power supply interruption.Reducing or resolving ATSE fault has become an important issue in power system maintenance.This paper presents a technical transformation plan of high frequency switching power supply for railway communication,which can solve the problem of DC power interruption caused by the simultaneous faults of ATSE and battery.
