主变铁芯多点接地引起色谱异常问题的分析处理

Analysis and Processing on the Problem of Chromatogram Abnormality Caused by Muti-point Grounding of the Main Transformer′s Iron Core

分析一台存在铁芯多点接地主变的绝缘油色谱,并通过诊断性试验及吊芯检查佐证了色谱分析结果,体现了绝缘油色谱分析在监测设备早期故障的重要作用。

Analysed the chromatogram of insulating oil in the main transformer with muti-point grounding iron core,and proved the chromatography analysis results by diagnostic test and transformer core suspended inspection.It reflects that the chromatography analysis of the insulating oil plays an important role in monitoring machine′s early faults.
