摘要
文章介绍了变电站直流系统的智能备自投装置,在一些特定的母线失压后自动判断故障并智能选择投入联络备自投,以避免直流母线停电带来的潜在事故。
This paper introduces the intelligent standby power automatic switching device of the DC system in the substation,which can automatically judge faults and intelligently choose to put into connection for automatic switching after a certain bus voltage lose to avoid potential accidents caused by the DC bus power failure.
