摘要
根据雷电电磁脉冲和电磁屏蔽理论,结合闪电频谱的特征、雷击风险评估的应用和几种不同金属材料屏蔽效能的对比,为铁路信号机房的雷电电磁脉冲屏蔽工程提供了一种设计思路,并给出一种屏蔽效能计算和验证的方法。
Based on the lightning electromagnetic pulse （LEMP） and electromagnetic shielding theory, combining with the features of lightning spectrum, the applications of lightning risk assessment and the comparison of shielding effectiveness of several different kinds of metal materials, the authors provide a design ideas for the LEMP shielding projeCt of the railway signal room, also give a method of calculating and validating the shielding effectiveness.
