中文摘要	局部放电的检测与分析是评价电力设备绝缘状况,发现早期故障的一种有效方法。与传统的脉冲电流法相比,甚宽带测量方法可以获取更多的局部放电信息,有助于提高测量的灵敏度和抗干扰能力。本文介绍了基于甚宽带脉冲电流法的局部放电检测系统,研究了传感器特性、脉冲分离技术和定量方法。并在实验室和现场对该系统的性能进行了测试,结果表明该系统具有灵敏度高和抗干扰能力强等优点,可以有效地应用于局部放电的现场检测和在线监测。; Partial discharge detection and analysis is widely accepted as an effective method to evaluate the insulation status and to figure out the possible defects and their severeness.Compared with traditional IEC method,the very wide bandwidth pulse current method could get more information about partial discharge,which will be helpful to improve the sensitivity as well as the ability of anti-interference.This paper introduces the partial discharge detection system using very wide pulse current method.The characteristic of current sensor,the pulse separation technology and pulse quantitative determination technology are studied.The high frequency current sensor has the bandwidth of 3-80MHz and the sensitivity of 16.5mV/mA maximum.The pulse separation technology could distinguish partial discharge signal from noise.The tests are carried in laboratory and field.The results show that it has the advantage of high sensitivity and anti-interference ability,which is very suitable for partial discharge on-site detection and on-line monitoring.
