摘要
以VDTC(VariableDischargeTimeConstant-变化的放电时间常数雷电回击模型)雷电通道模型为基础,衍生出仿真雷电通道的等效电路,由此电路仿真出相应的雷电电流波形,此波形与原始雷电流波形特征参数较吻合;利用此等效电路进行仿真计算,探讨阻性终端对雷电电流的影响。研究结果表明,阻性终端对雷电电流具有一定的抑制作用。
The paper gets the equivalent simulation circuit of lightning channel,which is derived from lightning channel model.The calculated lightning current by simulation circuit is identical with original lightning current.The paper discusses the effect of resistance on lightning return stroke current with calculating by simulation circuit.The result indicates that the lightning return stroke current is limited by resistance terminal.
