网络通信端口的电磁脉冲防护研究

Research on Electromagnetic Pulse Protection for Network Communication Port

电磁脉冲能通过天线、线缆、孔洞缝隙等途径,耦合非常高的能量进入电子设备,造成严重威胁。文中针对以太网数据通信端口的电磁脉冲防护问题,在介绍了传输线理论的基础上使用软件分别对平行双导线和双绞线进行了电磁仿真,设计了电磁脉冲防护模块,并通过实验验证了其良好的电磁脉冲防护性能。

Electromagnetic pulses can bring high coupling energy into electronic equipment by antennas, cables, gaps, and so on, causing serious threat. To protect the Ethernet data communication port, this paper uses the software to do electromagnetic simulation for parallel double wire and twisted pair respectively based on the theory of transmission line. The electromagnetic pulse protection module is designed and its good performance is verified by experiment.
