中文摘要：

文章目的是通过实验研究带有长控制导线装备的强电磁脉冲效应。通过静电放电实验发现了该装备的电磁效应；通过电快速脉冲实验验证了控制线是电磁干扰传播的重要通道，且干扰能“通过”光电耦合器件并导致装备死机；通过超宽带实验证实了强电磁脉冲场能在该装备的两芯传输线上激励高幅值的高频差模干扰电压信号。文中详细描述了实验方法，给出了干扰信号随传输线长度的变化规律，并分析了控制线末端差模干扰信号的产生机理和干扰信号“通过”光电耦合器件的机理。

英文摘要：

The purpose of this paper is to study the heavy electromagnetic pulse effects of a kind of equipment with long controlling transmission line by test. By ESD test it discover the electromagnetic effect of this equipment; By EFT test this paper validate the control line is a important channel for the spread of electromagnetic interference, and the interference signal can overpass the photoelectricity coupling compo- nent and induce serious fault in equipment; By UWB test it proves that heavy electromagnetic pulse field can excite high value difference mode interference signal of high frequency on the control line of this e- quipment The paper describe the test method in detail, give the rule of the interference signal varying with the transmission line length, and analysis the mechanism of exciting difference mode interference single at terminal of the control line and the interference single overpass the photoelectricity coupling component.
