电力设备线圈绝缘局部放电传输特性研究

Transfer Characteristic Research on Partial Discharge of Coil Insulation of Electric Power Equipment

局部放电测量是诊断电力设备线圈绝缘状况的一种重要方法。但传统方法测量得到的局部放电大小、波形与绝缘内部实际放电的大小和波形存在很大的不同。文章对电力设备线圈绝缘局部放电传输特性进行了研究 ,有关研究结果与试验观察的结果一致。

Measurement of partial discharge(PD) is very important for diagnosing coil insulation.But the measurement result with traditional method is different from that inside the insulation.The paper analyzes PD transfer characteristic of coil insulation and its result accords with experiment.
