摘　　要：为研究双绞线网络在雷电电磁脉冲场辐照下终端负载的感应电压,对树形双绞线网络进行辐照耦合试验。通过改变雷电电磁脉冲场波形、组成线缆网络的线缆夹角、线缆网络终端负载等条件,获得终端负载上的感应电压并分析响应规律。结果表明:雷电电磁脉冲场波形上升沿越快,双绞线网络终端负载的感应电压越大,而场波形的脉宽对终端负载感应电压基本无影响;线缆网络受测端负载感应电压随着线缆间夹角的增大而线性变小,但并不改变响应波形;线缆网络受测端负载感应电压随着受测端负载阻值的增加首先呈现线性增大的趋势,而后趋于平稳。In order to study the voltage of the terminal load for twisted pair network coupled with lightning electromagnetic pulse field, the tree-twisted pair network was irradiated. The voltage of terminal load and response law were accessed by changing waveforms of lightning electromagnetic pulse field, and the angles between twisted pair which formed network and terminal loads. It is found that the faster the rising part of lightning electromagnetic field waveforms is, the greater the induced voltage of the terminal load will be, and the pulse width has little effect on induced voltage. The induced voltage of the terminal load linearly decreases as the angles between twisted pair increase, but it does not change the waveforms of induced voltage. The induced voltage of the terminal load linearly increases firstly and then levels off with the increase of tested resistance.
