摘　　要：通过对UPS旁路停电UPS输出失去同步基准引发的DCS多个供电原件过电压烧损事件分析,查找出DCS供电系统存在的寄生回路,制订消除寄生回路方法,提高DCS供电可靠性。Based on the analysis of the over-voltage burn-out event of several DCS power supply components caused by UPS output out of synchronization benchmark due to UPS bypass power failure,the parasitic circuit of DCS power supply system was found out,and the method of eliminating the parasitic circuit was formulated to improve the reliability of DCS power supply.

关 键 词：UPS系统 同步 寄生回路
