电力变压器局部放电检测技术应用分析

Application Analysis of Power Transformer Partial Discharge Detection Technology

介绍脉冲电流法、高频法、超声波法和油色谱分析法等变压器局部放电检测技术的原理,结合这几种检测技术在变压器局部放电故障诊断中的应用,分析每种检测技术在判断不同类型变压器不同位置放电时的有效性,为局部放电检测方法的选择提供借鉴。

This paper first introduces the transformer partial discharge detection technology principles of the pulse current method, frequency method, ultrasonic method and oil chrom atographic analysis method,then combined with the applica- tion analysis on these detection technology on transformer fault diagnosis, finally presents the effectiveness of these de- tection technology in different types discharge and different positions discharge of the transformer to take reference for the chosen of partial discharge test method.
