摘要
本文作者在统计分析20例500kV及以上电压等级大型变压器绕组匝间短路故障实例的基础上,重点介绍有关故障录波和在线油色谱的特征,并对提高绕组匝间短路故障预警的有效性提出建议。
On the basis of statistical analysis of 20 cases of breakdown between turns in large transformer windings with voltage levels of 500kV and above,this article focuses on introducing the characteristics of fault waveform recording and online oil chromatography,and puts forward suggestions for improving fault warning effectiveness of winding breakdown between turns.
