摘要
针对华能东方电厂一起6kV母线因保护越级动作造成的失压事件,试验剖析其根本原因,并针对性地制订防范措施,对真空接触器的选型、日常维护、检修、预防性试验及继电保护整定计算等工作有良好的指导作用。
To the accident of a 6 kV bus voltage loss caused by the overstep action of protection in Huaneng Dongfang Power Plant,the root causes were analyzed through experiments,and the preventive measures were formulated accordingly.It had a good guidance for type selection,the daily maintenance,inspection,preventive test and relay protection setting calculation of vacuum contactor.
