电力变压器绝缘油色谱氢气超标故障的分类分析

Classification and Analysis of Abnormal Hydrogen Gas Fault of Power Transformer Oil Chromatography

本文中作者介绍了三起电力变压器绝缘油色谱氢气含量超标的典型故障案例,结合其分析处理过程,对比分析了引起变压器油色谱单独氢气含量超标、其他气体组分较小的三类典型故障原因,总结了不同类型故障的色谱特征及其区别分析方法。

This paper introduces three typical fault cases of exceeding hydrogen content in transformer oil chromatography.Combined with its analysis and processing process,it compares and analyzes the fault causes concerning exceeding hydrogen content alone and too little of other gas components in transformer oil chromatography.The chromatographic characteristics of different faults and their distinguishing analysis methods are summarized for reference.
