摘要(Abstract)：

分析了GIS超声波和特高频检测测量技术的优缺点,构建了252 kV GIS局放仿真平台,并测试了平台的一、二次电压相角差。设置了导体尖端和壳体内部尖端电晕放电缺陷,借助仿真平台获取测量信号,详细分析了在这类缺陷下特高频和超声波信号的特征及规律,为GIS带电检测诊断提供参考。
This paper introduces advantages and disadvantages of ultrasonic wave and UHF testing techniques for GIS. Simulation platform for 252 kV GIS partial discharge is established and the phase angle difference of primary and secondary voltage of the platform is tested. Point corona discharge defects of conductor and shell are set, and testing signals are obtained by means of the simulation platform. Thus, the paper analyzes the characteristics and laws of UHF and ultrasonic wave signals in case of such defects, providing references for live detection and diagnosis of GIS.
