摘要

局部放电带电检测是判断特高压变电站GIS设备内部绝缘状况的重要手段之一。为分析不同带电检测方法的检测效果

依托1 100 kV GIS真型试验平台

设计了5种内部缺陷

并对缺陷模型进行了仿真计算。在仿真分析基础上

对其内部缺陷进行了试验研究

复现了GIS设备内部的真实放电。根据试验结果

利用雷达图的评价方法

对特高频法、超声波法、高频电流法局部放电带电检测的有效性进行了比较分析。试验及比较分析结果为研究1 100 kV GIS设备内部缺陷特征积累了经验

并对指导特高压变电站GIS设备的带电检测工作

以及多种检测方法的融合应用提供了数据支撑

并具有一定的借鉴价值。

Abstract

Live test of partial discharge is one of the most important method to judge internal insulation condition of GIS equipment in UHV substation.In order to analyze the effect of different live test methods

internal defect models were established on the real type testing platform of 1 100 kV GIS.Then simulations and experimental research were carried out on the defect models.According to the test results

the effectiveness of the partial discharge live tests

including ultra-high frequency method

acoustic emission method and high frequency current method

was comparatively evaluated using radar graph.This study may facilitate the research of internal defect features of 1 100 kV GIS equipment

and provide data support to the live detection of GIS equipment in ultra-high voltage substation and to the integrative application of multiple detection methods.
