一起变压器重瓦斯动作引发的思考

Reflection on the Heavy Gas Relay Action of a Transformer

以某变电站一台变压器因油位降低导致重瓦斯动作为例,通过对比分析国内外不同类型的瓦斯继电器结构和工作原理,结合现场检验分析,对此次瓦斯继电器动作情况给出明确结论,并举一反三提出了关于瓦斯继电器的若干建议。

Taking heavy gas protection action caused by lowered oil level of a transformer as an example, different types of gas relay home and abroad are compared and analyzed in terms of the structure and working principles. Based on the analysis of field test, the situation of gas protection action is summarized and suggestions are put forward on gas relay protection.
