摘要

通过对静电探头法测量表面电荷分布的原理进行分析

提出了一种基于广义静电探头法的表面电荷在线监测新方法。研究表明:当气体绝缘开关设备（G IS）中绝缘子表面存在静电荷时

会在金属导体上感应明显的电压信号。通过测量这个电压信号可以实时检测绝缘子表面电荷积聚的严重程度。进而可以大大减少绝缘子表面的闪络几率

提高电力系统的安全。

Abstract

The theory of electrostatic probe method used to measure surface charge distribution is analyzed and a new method used to monitor surface charge on line which is based on generalized electrostatic probe is presented.It shows that when static charge is loaded on the insulator in GIS

voltage signal will be induced on the metal conductor.Through measuring the voltage signal

accumulation degree of the surface charge on the insulator can be detected in real time.So the flashover on surface of the insulator can be reduced greatly and the safety of the power system can be increased.
