GIS设备局部放电诊断方法及性能对比研究

Research on Partial Discharge Diagnosis Method and Performance Comparison of GIS Equipment

GIS设备作为我国电网设备中最常见的设备之一,其绝缘性故障常常会导致事故的发生。局部放电作为绝缘性故障中较为常见的一种故障,需要运用一系列诊断方法对其故障类型和位置进行判别。因此,对目前GIS设备局部放电诊断中常见的4种方法的原理进行分析,并对4种方法的性能进行了对比分析。

GIS equipment is one of the most common equipment in China's power grid,its insulation fault often leads to accidents,and partial discharge as a more common fault in insulation fault,we need to use a series of diagnostic methods to identify the fault type and location.In this paper,the principle of four common methods in PD diagnosis of GIS equipment is analyzed,and the performance of these four methods is compared and analyzed.
