电磁脉冲电缆耦合模拟试验技术与测试技术

摘要

The simulation of Internal Electro Magnetic Pulse(IEMP) coupling with Electro Magnetic Pulse(EMP) coupling in sealed cavity without space charge limit is described in detail. The research of coupling models contains magnetic field coupling to cable,electric field coupling to cable, charge or radiation coupling on the surface of cable. The voltage source and current source in the lumped parameter equivalent circuit are adopted to express the theoretical models of electric field coupling,magnetic field coupling and charge coupling. The space charge current and space charge density are distribution function dependent on space and time. The current and field induced by the IEMP coupling of charged cable and space charge are researched;the influence of the trends, types, bias and terminal loads of the cable,are observed. The test and theoretical results are obtained.%详细介绍了非空间电荷限制条件下进行的模拟密封腔体内测量内电磁脉冲(IEMP)耦合与电磁脉冲(EMP)耦合的实验.耦合模型的研究内容包括磁场耦合到电缆、电场耦合到电缆以及电荷淀积或辐射从电缆表面耦合.耦合模型可将电场、磁场、电荷淀积的耦合方式用集总参数等效电路内的电压、电流源表示理论模型.空间电荷电流和空间电荷密度象强源一样,是依赖于空间和时间的分布函数.针对带电电缆的IEMP环境耦合与辐射感应电子发射产生的空间电荷对产生的电流和场进行研究,并观察电缆走向、类型、偏置和终端负载的影响,得出了理论与试验结果.
