摘要
针对一起220 kV主变跳闸事故下形成罕见的运行方式进行了原因分析,简要阐述了事故处理过程,分析了因110 kV禄口变主变35 kV侧开关未跳开情况下备自投动作后形成的降压供电方式以及存在的潜在危险点总结了调度员在面对这类特殊事故时的处理思路及应对措施。
Analysis focused on an abnormal operation mode caused by a trip accident of main transformer of 220kV has been conducted in this paper.And recovery procession of this accident is also given.Analyzed reduced voltage supply mode and potential dangerous nodes,which are caused by the action of automatic switching device on the condition that the switch has not tripped on the 35kV side of the 110kV main transformer in Lukou substation.Solutions and processing thinking for dispatchers when dealing with such special accidents are also summed up.
