| 摘 要： | 用传输线法对高空电磁脉冲作用下地面电缆屏蔽层感应电流进行了数值模拟，得到了电缆皮电流随入射场波形、电缆长度、电缆屏蔽层两端接地状态的变化规律，部分计算结果与时域有限差分法计算结果及实验结果进行了比较，它们间有较好的一致性。

| Abstract: | In this paper, the transmission line method are used to calculate the HEMP induced skin current in cable shielding near ground. The change law of cable skin current with waveform injecting field, cable length and grounding state of shielding layer of cable was obtained. The calculating results indicate that the waveform of skin current is closely related with the skin grounding condition and when the peak magnitudes of injecting field are uniform, the wider the waveform of injecting field, the larger the skin current. A part of calculated results are compared with the calculated ones of FDTD method and experimental ones. There is good consistence between them. |
