电磁兼容性(EMC) 第5-3部分:安装和调试指南 HEMP保护概念

[中文适用范围]： IEC 61000 的这一部分定义并提供了有关针对高空核爆炸（以下缩写为 HEMP 表示）电磁脉冲的保护概念的信息。本技术报告的目的是提供以下要素： - 设计针对 HEMP 的民用设施的充分保护； - 对 HEMP 施加的压力的现有保护进行评估； - 比较 HEMP 和防雷的要求，以表明它们是否可以低成本组合； - 强调 HEMP 和防雷要求之间的差异，以便在不采取现有防雷之外的其他措施时评估 HEMP 的后果。 [外文原描述]： This technical report provides elements for: - the design of an adequate protection for civil facilities against the electromagnetic pulse due to a high altitude nuclear explosion, denoted in what follows by HEMP; - the evaluation of already existing protections with respect to stresses imposed by HEMP; - to compare the requirements of HEMP and lightning protection in order to show if they can be combined at low cost; - to emphasise the differences between the requirements of HEMP and lightning protections in order to permit the evaluation of the consequences of HEMP when no additional measures are taken except existing lightning protection.
