主变压器绕组电阻异常分析及处理

Abnormal Resistance Analysis and Treatment on Main Transformer Winding

介绍某变电站3号主变压器绕组电阻异常的情况,通过对比绕组电阻数据变化的规律,分析认为油纸电容型套管引线连接不良是导致变压器绕组电阻异常的主要原因,并提出相应的处理措施及建议。

This paper introduces winding resistance anomalies of some substation No 3 main transformer, compares with the winding resistance data changes rules, considers that oilpaper capacitor bushing unwell line connection is the main cause after analysis, and advances corresponding treatment measures and suggestions.
