特高频法在GIS局部放电检测与定位上的应用

Application of Partial Discharge Detection and Location for GIS Based on Ultra-high Frequency Method

特高频法因其抗干扰能力强,检测效率高,检测灵敏度高等优点,成为被广泛用作GIS带电检测的主要手段。阐述了在GIS设备中运用特高频法检测的原理和定位方法,结合某内部绝缘缺陷的案例对检测分析和定位过程进行详细介绍,提出了判别缺陷类型的方法和策略,可为相关工作提供参考。

Ultra-high frequency（UHF） method is widely used as the main means of live detection for GIS equipment due to its strong anti-interference ability, high detection efficiency and sensitivity. In this paper, the UHF detecting principle and locating method were discussed. Combined with a typical case of internal insulation defect,this paper introduced the application of UHF method in detail to detect and locate partial discharge for GIS and put forward strategies to distinguish defect types, which can provide references for related work.
