摘要
本文笔者通过多例变压器类设备局部放电试验录像的回放分析,包括对“偶闪”脉冲的分析,发现了放电缺陷,对完成在变压器工厂的后续试验,确保设备在现场的安全运行,和故障诊断都有重要意义。
Through the playback analysis of multiple partial discharge test videos of transformer products,including the analysis of"occasional bursts",the discharge defects are discovered,which is of great significance for transformer factory accept testing,then ensuring the safe operation of equipment on site,and fault diagnosis.
