【摘要】 为了更好了解局部放电UHF信号在GIS中的传播和衰减特性,研制了一种纳秒级脉冲源,用于模拟GIS中局部放电信号,并采用实验和XFDTD仿真相结合的方法分析了此纳秒级脉冲信号在GIS内的衰减特性。实验结果和仿真结果综合表明,研制的纳秒级陡脉冲源完全可以模拟GIS内部的局部放电,利用XFDTD仿真软件建立的GIS局部放电模型是正确的、可行的。更多还原

【Abstract】 In order to get more knowledge of the propagation and attenuation characteristics of the UHF signal in GIS,to economize the UHF sensor in GIS station,this paper develops a nano second pulse generator.It analyzes the propagation characteristic of the UHF signal in GIS using the experimental method and XFDTD emulation method.The result shows the generator can simulate completely the GIS internal partial discharge,and the model is correct and feasible.更多还原
