摘要

摘要: 高空电磁脉冲(HEMP)是一种能够通过场线或孔缝耦合到各种电子电气设备内部的暂态电磁波，该电磁能量会对正常工作的电子电气设备造成干扰甚至永久性损伤。为了确保关键部门的安保系统能够在电磁脉冲环境下正常工作，有必要针对安保系统进行电磁脉冲效应试验，分析该种类型系统在电磁脉冲环境下的薄弱环节和生存能力。针对核安保典型系统拓扑结构，搭建了电磁脉冲辐照试验和脉冲电流注入试验平台，并通过试验获取了报警分机、门禁主机、报警中心端等核安保典型系统关键部件的电磁脉冲效应阈值和效应现象。进一步结合各部件的电路原理分析了关键部件的失效机理，总结了核安保典型系统的薄弱环节，为后续安保系统的防护加固设计提供数据支撑。

Abstract: High-altitude electromagnetic pulse(HEMP) is a kind of transient electromagnetic wave which can be coupled into various electronic and electrical equipments through field lines or holes. To ensure that the security system of key departments can work normally under the electromagnetic pulse environment, it is necessary to carry out the electromagnetic pulse effect test against the security system, and analyze the weak link and survival ability of this kind of system under the electromagnetic pulse environment. According to the topology of nuclear security system, the electromagnetic pulse radiation test and pulse current injection test platform are set up, and the threshold and effect phenomena of the key components of the nuclear security system are obtained through the test. Furthermore, the failure mechanism of key components is analyzed based on the circuit principle of each component, and the weak link of typical nuclear security system is summarized, which provide data support for the protection and reinforcement design of the follow-up security system.
