摘　　要： 变电站直流系统在变电站内是相对独立且非常重要的一个电源系统,主要为变电站的控制、信号、综保、自动装置及事故照明等提供可靠的直流电源,同时也为变电站内开关的分合闸操作提供电源。直流系统的可靠性直接影响到变电站的安全稳定。此文通过对某变电站直流系统中实际故障的处理分析,期望引起对故障排查的重视,加强对直流系统的维护。 DC system of a substation is a relatively independent and important power supply system in substation,which provides reliable DC power supply for substation control,signal,integrated protection, automatic device and accident lighting and so on, and provides power supply for breaking-closing operation of switch in the substation.The reliability of DC system directly affects the safety and stability of the substation. Through the analysis of the processing of the actual fault in the DC system of a substation, this paper expects to attract attention to the troubleshooting and strengthen the maintenance of the DC system.
