摘　　要：无论是对于变压器产品质量的控制,还是电气设备运行中的绝缘诊断,局部放电检测都是十分有效的手段。为此,建立变压器绕组的高频脉冲传播仿真模型,同时快速准确地对局部放电进行定位。其结论对于研究放电脉冲在变压器绕组中的传播机理,迅速排除故障、保障电力系统的正常运行具有重要意义。Discharge detection is a very effective method for transformer product quality control and insulation diagnosis in the electrical equipment operation. Studies the building of the high - frequency pulse spreads model in transformer winding and the fast and accurate location of the partial discharging. The conclusion has A important values to study the spreading mechanism of the discharging pulse in transformer winding, clear up any problems quickly, to protect the operation of power system smoothly.
