摘要

SF6气体绝缘变电站（GIS）的在线监测技术在电力系统中得到了越来越广的应用

并取得了显著成效

但对于在线监测装置的现场校验与量化评价方面仍存在诸多问题。文中通过建立1 100 k V GIS在线监测缺陷模拟平台

实验得到了不同缺陷模型的GIS内特高频信号谱图与视在放电量

开展了特高频信号在GIS腔体内的传播衰减特性分析研究

利用脉冲注入法得到了注入脉冲与视在放电量的等效性关系与典型GIS设备特高频信号衰减特征值

为GIS在线监测系统现场校验技术提供了理论基础。

Abstract

Online monitoring of gas insulated substation（GIS）is increasingly applied in power system

and remarkable effect has been obtained. But there are still many problems in the field calibration and quantitative evaluation of online monitoring devices. The paper establishes a defect simulation platform for online monitoring 1 100 k V GIS

obtaining the detection UHF spectra and the apparent discharge quantities through experiment. The attenuation propagation characteristics of UHF signal in GIS are studied. By using the pulse injection method

obtaining the relationship between steep pulse injection and the apparent discharge capacity

and the characteristic value of the typical GIS attenuation is obtained

which provides a theoretical basis for field verification technology for a 1 100 k V GIS online monitoring system.
