高强辐射场(HIRF)对各种电力、电子设备的威胁目益加大。从几种常见的屏蔽线缆入手,以基于矩量法的商用电磁仿真软件FEKO为工具,研究HIRF环境对线缆的影响。分析了不同极化方向、电磁场频率、屏蔽线缆与地面距离以及屏蔽层数对仿真结果的影响,得出了在HIRF环境下的电缆耦合规律。
Threatening of high intensity radiation field to every kind of power and electronic equipment is increasing day by day. From several common shielded cables to start with, taking commercial electromagnet simulation software FEKO based on a moment method as the tool, this paper studied the impact of high intensity radiated field (HIRF) environment on cables and analyzed the po- larization direction, electromagnetic frequency, distance between shielded cable and land surface and shielded layer number of impacts on simulation result, so that the cable coupling patterns under HIRF environment are obtained.
