| 摘 要： | 屏蔽电缆对电磁脉冲辐射场的耦合特性对电子设备、系统的电磁干扰控制和电磁脉冲防护具有重要意义。研究屏蔽电缆的双传输线模型分析方法,计算不同频段电磁脉冲辐射场激励下,两种典型的屏蔽电缆在屏蔽层两端不同接地状态时,屏蔽层和芯线上的感应电流。编织屏蔽电缆芯线上的感应电流比管状屏蔽电缆大几个数量级;由于集肤效应的影响,管状屏蔽电缆芯线上的耦合随着频率的升高而降低;编织屏蔽电缆由于编织电感和小孔电感的影响,芯线上的耦合随着频率的升高而升高。对于高灵敏的高频、微波系统,对电磁脉冲的防护时要选用管状屏蔽电缆。

| Abstract: | The study of the coupling characteristics of shielded cable in an EM pulse radiation field both for EMI control and EMP protection on electrical equipment and systems becomes absolutely essential.A double-transmission-line model of shielded cable was therefore investigated.The coupling current response on the shield layer and inner conductor of two typical shielded cables in different grounding states and range of frequency of EMP field were calculated.The coupling current on the inner-conductor of braid sh... |
