摘要
超高频的局部放电测量是目前国外电力设备绝缘检测研究的焦点问题之一。本文建立了一套超高频局部放电的测量系统 ,设计了XLPE电力电缆及其接头局部放电超高频测量的电容耦合传感器 ,分析了传感器的等效电路 ,测量了其频率响应 ,对电缆以及接头中的实际放电进行了测量分析。
UHF partial diacharge measurement has been one of the main research items for the power equipment insulation.This paper presents the principle of UHF partial discharge measurement using capacitive coupler.The equivalent circuit of capacitive coupler is analyzed,and the frequency response of the coupler is measured.The UHF measurement set\|up can measure the practical discharges on a cable and a cable with joint.
