| 摘 要： | 介绍了局部放电电流法检测局部放电的基本原理,给出了振荡波局部放电测试电路,对基于这一检测原理的振荡波局部放电测试系统检测的波形信号进行分析。研究表明振荡波检测系统检测的局部放电信号会受电缆传播特性的影响产生衰减,且检测的信号波形基本上呈现脉冲型和脉冲振荡衰减型两种形态。

| Abstract: | Introduction was made to the basic principle of partial discharge current method to test partial discharge. This paper gave the testing circuit of partial discharge based on oscillatory wave and analyzed waveform signals of oscillatory wave partial discharge test system based on the testing principle. The research result shows that the partial discharge signals affected by the propagation char- acteristics of power cable generated attenuation. The detected signal waveform basically presented pulse shape and pulse oscillatory at- tenuation shape. |
