| 摘 要： | 某220kV变压器现场交接试验中，长时感应电压带局部放电测量试验三相局放量均超标，通过试验测量及原因分析，确定了放电位置，最终确认局放量超标原因是在安装三相高压套管时，套管末端均压罩未装紧固螺栓。经处理后，该主变通过了局部放电试验。

| Abstract: | In Field handover test of a 220 kV transformer, inducted voltage test and partial discharge test three-phase board volume all exceed the standard. Through testing method and analysis, the discharge position is located. Real reason for exceeding standard vol- ume is that in the installation of three-phase high voltage bushing, equalizing cover is fixed without fastening bolt in sleeve end. After processing the main transfurmer passed partial discharge test. |
