电磁脉冲传导干扰环境与抗扰度测试系统

Environment of EMP conducted disturbance and immunity test methods

核电磁脉冲传导干扰是电磁防护研究的一项重要内容。随着设备与系统信息化和网络化程度的不断提高,各类设备使用的金属线路种类繁多、规模庞大,电磁脉冲通过线缆耦合对电子、电气设备及控制系统的安全运行构成了严重威胁。本文根据有关国际标准对核电磁脉冲形成的传导干扰环境进行了分析和总结,在此基础上组建了传导干扰抗扰度的测试系统,对其实际应用进行了实验。

The protection against the conducted disturbance caused by nuclear electromagnetic pulse（NEMP）plays an important role in defense electromagnetism. With the development of informatization and intelligentize in the equipment, the variety and quantity of metallic wires passing through the equipment increase rapidly. NEMP carried by the coupling of these transmission lines can cause great disturb- ance or damage to the electrical and electronic apparatus and control system. In this peper, the environment of EMP conducted disturbance is analyzed and summarized. The EMP conducted disturbance test system is made in this base and used for the experimentation.
