一起500kV主变压器油色谱异常的分析及处理

Analysis and Treatment of Abnormal Chromatographic Data of Oil in 500kV Main Transformer

本文中作者介绍了大型电力变压器油中总烃含量超标的综合分析和处理过程,通过对油中特征气体进行排序法、二比值法、三比值法分析,对变压器故障类型及故障位置进行了判断。

The analysis and treatment of abnormal total hydrocarbon content in main transformer oil is introduced by the authors in this paper.Through the sorting method,the two-ratio method,the three-ratio method of characteristic gases,the fault type and fault location of the transformer are analyzed.
