摘要

为了能及时掌握GIS设备绝缘情况

有必要对其进行局部放电在线监测。结合目前UHF发展现状

分析某220 k V变电站一起局部放电案例指出

通过改变设备的运行方式和采用多种检测仪器综合诊断可以有效排除检测仪器本身和外界环境等不确定性干扰因素

提高监测结果和定位的准确性

为解体处理带来方便。运行经验表明

安装GIS设备UHF局部放电在线监测系统

可以及时发现隐患

确保设备安全稳定运行。

Abstract

To timely understand insulation state of GIS equipment

on-line monitoring of partial discharge is necessary. According to the existing UHF methods and the analysis on a partial discharge case of a 220 k V substation

the authors propose that by changing the operation mode of GIS equipment and using a variety of testing instruments for integrated diagnosis

the uncertain interferences from instrument itself and external environment can be effectively excluded. Hence the accuracy of partial discharge monitoring and positioning results can be improved. The proposed method may facilitae disassembly processing. Operational experience shows that the UHF partial discharge monitoring system installed on GIS equipment can timely detect hidden troubles to ensure safe and stable operation of the equipment.
