摘　　要：局部放电(PD)监测对GIS设备的维护起着重要作用,特高频(UHF)检测方法因其高灵敏度和抗干扰能力强而引起了许多研究者的极大兴趣。研究了GIS设备中四种典型缺陷的固有特征,如频谱特征和相位分布,探讨了四种典型缺陷模型的固有特征。研究结果显示了局部放电的基本特征有助于提高特高频检测方法的灵敏度和抗干扰能力。Partial discharge(PD)monitoring plays an important role in the maintenance of GIS equipment.In recent years,ultra-high frequency(UHF)detection methods have attracted great interest from many researchers due to their high sensitivity and strong anti-interference ability.This paper focuses on the inherent characteristics of four typical defects in GIS equipment,such as spectral characteristics and phase distribution,and discusses the inherent characteristics of four typical local discharge sources.Results demonstrate the basic characteristics of partial discharge,which can be used to improve the sensitivity and anti-interference ability of ultra-high frequency methods.
