两种变压器油色谱分析方法对比

Comparison of Two Methods of Transformer Oil Chromatographic Analysis

油色谱分析作为变压器故障诊断的重要手段,熟练掌握其分析方法有着重要意义。为此,介绍了三比值法与三角形判据法两种变压器油色谱分析方法,选取有代表性的典型变压器故障案例对比了两种方法分析的优缺点,并结合一起变压器故障案例讨论使用时需注意的问题,在变压器故障诊断方面为研究人员提供了参考。

Oil chromatography analysis is an important means of transformer fault diagnosis,and it is of great significance to master oil chromatography analysis methods.Therefore,two transformer oil chromatographic analysis methods,three-ratio method and triangle criterion method,are introduced,and representative typical transformer fault cases are selected to compare the advantages and disadvantages of the two methods.Combined with a transformer failure case,the problems that need to be paid attention to when using are discussed.This study provides a reference for researchers in transformer fault diagnosis.
