基于绝缘油色谱试验的110kV变压器异常状态分析

Analysis of Abnormal State of 110kV Transformer Based on Insulation Oil Chromatography Test

本文作者针对某110kV变压器绝缘油色谱数据异常情况,参考高压试验结果,运用产气速率判断法、特征气体法、改进三比值法、比值判断法,分析了油色谱试验数据,并诊断了故障类型。最终吊罩检查变压器,明确了故障点,并对此次事故进行了总结。

The author focuses on the abnormal situation of the insulation oil chromatogram data of a 110kV transformer.Referring to the high-voltage test results,the gas production rate judgment method,the characteristic gas method,the improved three ratio method,the ratio judgment method are used to analyze and diagnose the oil chromatography test data from multiple aspects.Finally,through the transformer hanging cover inspection,the accident point is identified,and the accident is summarized.
