摘要
通过对一起直流系统失电引起两台机组跳闸的事故分析,得到导致直流系统失电的原因为蓄电池充放电试验中误操作,根据事故原因,进而对直流系统的运行方式进行了分析,指出当前运行方式存在的问题,从提高直流系统供电可靠性的角度提出了改进措施。
After two machine sets＇ tripping accident caused by a direct current system＇s electrical breakdown was analyzed, the reason leading to the accident was the misoperation of storage battery＇s charge and discharge. According to the accident reason, this paper analyzed the run mode of the direct current system, pointing out the problem existing in the run mode and raising improved measures from the aspect of enhancing the power supply reliability of the direct current system.
