摘　　要：为有效检测局部放电故障,同时快速定位局部放电位置,采用局放特高频信号空间搜索定位方法对放电源进行定位,同时用XFDTD电磁场分析软件对局部放电定位进行仿真计算。结果表明,空间搜索定位方法可以对故障源进行快速定位。所提方法定位速度快,误差小,对确保变压器设备安全运行具有重要意义。In order to effectively detect the partial discharge faults and quickly locate the location of the partial discharge,the partial discharge ultra high frequency signal space search and positioning method was used to locate the discharge source,and at the same time XFDTD electromagnetic field simulation was also adopted to simulate and calculate the partial discharge location.The results show that the spatial search and location method can quickly locate the fault source.The location method is characterized by fast location speed and small error,which is of great significance to ensure the safe operation of transformer equipment.
