摘要
本文针对一起某发电厂500kV主变压器绕组温度计误发绕组温度高信号,引起运行中的660 MW发电机组跳闸全停的故障进行分析,为发电厂变压器绕组温度保护的运行管理、保护的设计、类似故障分析提供参考。
The tripping failure of 660 MW generator caused by high temperature signal of winding thermometer in a 500 kV main transformer was introduced.This paper provided reference for operation management,protection design and similar fault analysis of transformer winding temperature protection in power plant.
