摘要
超高频(UHF)局部放电在线监控系统可预防气体绝缘金属封闭开关设备(GIS)发生灾难性故障。文章对超高频局部放电实时监视系统的基本结构、局部放电试验情况进行了介绍,并给出了在韩国运行的2个应用案例。超高频局部放电实时监视系统的数据库储存有试验室条件下的各种超高频局部放电和现场实际运行中的故障信号,安装该监控系统后,非专家也可以判断出气体绝缘金属封闭开关设备的状态。
The UHF partial discharge online monitoring system can prevent the disastrous fault for GIS. The basic structure of UHF partial discharge real time monitoring system and the test condition of partial discharge were introduced, and the 2 application cases in operation in Korea were given. The database of the monitoring system can store the fault signals in the actual operation on-the-spot and the various partial discharges of ultrahigh frequency under lab condition. After installing this monitoring,system, the state of GIS can be judgod by the person who is not an expert.
