摘要
一次110V直流控制电源异常引起保安PC段母线备用电源开关跳闸,对母线失压的原因进行了分析,发现该系统在设计和选型方面存在许多问题,提出了解决方案,彻底消除了因直流电源消失而造成的下级开关误动的问题。
Once,an abnormal condition of 110V DC control power source caused the switch of the standby power source of PC bus of emergency power supply to trip. The reason of the bus voltage failure was analyzed,and it was found that there are many problems in the system design and device selection of the system. The solution was put forward,and the problem,which is that the DC power supply failure causes the switch in lower level to trip incorrectly,was solved thoroughly.
