变压器绕组直流电阻超标缺陷的综合判断

Colligation Estimation of Transformer Winding Direct Current Resistance Over-standard

针对变压器绕组电阻试验数据超标的情况,在对试验数据进行纵向对比的基础上,结合油色谱分析和红外测温图谱分析,判断出变压器的缺陷部位在高压套管V相柱头处,并分析缺陷产生直流电阻超标的原因,提出缺陷处理措施和整改建议。

Aiming at test data resistance over-standard of transformer winding resistance,with test data longitudinal contrast and gas dissolved in power transformer oil analysis and infrared temperature measurement atlas analysis,this paper considers that the defect part is on the high voltage bushing V necking part,and analyzes the reason,puts forward the settlements and suggestions.
