摘要
简要介绍了一些局部放电的基本概念和AE-PD型超声波局部放电测试仪的工作原理,并根据电容器超声波局部放电典型波形分析来对比分析实际测量中电容器超声波局部放电波形所反映的电容器的内部质量问题,最后通过对电容器在常温下极间局部放电与极对壳局部放电数据分析以及电容器在常温下极间局部放电与低温下极间局部放电中出现的试验现象分析,各自总结出了一些判别经验。
This paper briefly introduces some basic concepts of partial discharge and working principle of AE-PD type ultrasonic partial discharge detector. According to the analysis of the typical waveform of capacitor ultrasonic partial discharge, A comparative analysis is made on the internal quality of the capacitor reflected by the ultrasonic partial discharge of the capacitor in the practical measurement. Finally,through the analysis of the partial discharge data of interelectrode and pole-to-case under normal temperature, as well as the analysis of the test phenomenon in interelectrode partial discharge under normal temperature and low temperature, some experiences are summarized.
