变电所的电磁防护

On the Electromagnetic Protection of the Substation

本文介绍了变电所电磁干扰产生的来源及电磁干扰的危害，对电磁干扰进行了建模，分析了通过抑制干扰源、切断传播途径、提高设备本身抗干扰能力、防雷技术等防范措施来消除电磁干扰，保证无人化牵引变电所的可靠运行。

This paper introduces the cause and its harm of electromagnetic interference in substation. The electro- magnetic interference has been modeling, through the analysis of the interference source, cut off the route of transmission, improve the antijamming ability of equipment itself, lightning protection technology to eliminate electro- magnetic interference and ensure the security of unmanned substation.
