摘　　要：为了能更加清晰直观了解局部放电现象的传播特点,通过时域有限差分法在SolidWorks软件中建立开关柜物理模型,并将其以.sat文件导入XFDTD实施仿真分析。探索了变电所开关柜局部放电的电场强度与观测位置、激励源幅值、脉冲宽度等因素之间的关系。另外,通过提高激励源幅值来模拟电气化铁路因列车通过导致牵引负荷波动性较大的特点。In order to understand the propagation characteristics of the partial discharge phenomenon more clearly and intuitively,the physical model of the switchgear is established in the SolidWorks software through the finite difference time domain method,and the switchgear is imported as a.sat file into XFDTD for simulation analysis.The relationship between the electric field intensity of the partial discharge of the switchgear of the substation and the observation position,the amplitude of the excitation source,the pulse width and other factors are explored.In addition,by increasing the amplitude of the excitation source,it simulates the characteristics of the electrified railway that the traction load fluctuates greatly due to the passage of trains.
