Application Case of Mobile Online Monitoring and Load Monitoring in GIS Fault Detection
主要介绍一起移动式在线监测及局放定位在GIS故障检测中的成功应用案例。针对佛山局某220 k V变电站110 k V GIS常规红外检测出现异常的情况
采用移动式局放在线监测系统
结合GIS母线负荷监测技术发现GIS内部缺陷。解体发现该GIS 2号气室第2个连接触头等位线断线
此处支柱绝缘子螺丝松动
支柱绝缘子存在放电痕迹。说明了移动式在线监测方法结合母线负荷监测技术在GIS故障检测中的可行性
值得推广使用。
Abstract
A successful application case of mobile online monitoring and partial discharge positioning in GIS fault detection.Aiming at the abnormal conditions detected by conventional infrared in 110 k V GIS at 220 k V substation in Foshan
the mobile partial discharge online monitoring system
combined with GIS bus load monitoring technology
is used to find out the internal defects in GIS.Through disintegration of the GIS
it is found that the equipotential line at the second contact in the No.2 gas apartment is broken
the pillar insulator screw is loosening
discharge trace is found on the pillar insulator
which means that the online monitoring method of mobile type combination with bus load monitoring technology in GIS fault detection is feasibly and may have value to be applicable.
