2Effect of disconnector and high-voltage conductor on propagation characteristics of PD-induced UHF signals显示文摘UHF(ultra high frequency)method has been widely used in PD(partial discharge)detection for its high sensitivity.The resonance,distortion,and attenuation appearing in the propagation process of UHF signals in GIS(gas insulated switchgear)will influence the real situation of PD detection.Therefore,it is necessary to investigate the effect of GIS components such as disconnectors or high voltage conductors on the propagation characteristics of PD-induced UHF signals in various voltage classes GIS.The factors of PD signals propagation characteristics in axial and radial directions are both analysed to avoid the effect caused by placement of sensor in this paper.First,the simulation models of GIS are built based on FDTD(finite difference time domain)method.Then the propagation characteristics of PD-induced UHF signals are studied in the GIS with different disconnector gap lengths and different high voltage conductor radii.Finally,the reliability of the simulation results is verified by compared with laboratory tests.The disconnector gap and the change of conductor radii can both result in the signals attenuation which rises highest in the direction of 180°.The lower the GIS class voltage is,the larger the attenuation of signals after passing through disconnector gap is.Minxia Shi Xutao Han Xuanrui Zhang Zheming Zhang Junhao Li 2018High Voltage2018,3,3:2
