摘　　要：本文介绍了一起500kV电抗器轻瓦斯保护动作故障案例,对故障电抗器瓦斯继电器的结构及轻瓦斯动作原理进行了说明。通过分析得出了此次轻瓦斯保护动作是由于维护后对油气分离盒处理不当以及油气分离盒结构不合理等原因造成的结论,并提出了电抗器维护中应注意的事项及油气分离盒结构改进的意见。This article introduces a case of light gas protection action failure of a 500kV reactor and illustrates the structure of the gas relay of the fault reactor and the principle of light gas action. The analysis shows that the light gas protection action is caused by improper treatment of oil-gas separation box after maintenance and unreasonable structure of oil-gas separation box, and the matters demanding attention during the maintenance of the reactor as well as the suggestions regarding upgrading the structure of the oil-gas separation box are put forward.
