| 摘 要： | 阐述了雷击电磁脉冲(LEMP)对信息设备的危害,以计算及实例说明LEMP的危害与雷击点的距离成反比,雷击概率N与雷击点高度h的平方成正比。N越高,LEMP的危害就越大。LEMP是信息防雷的重点,应采取屏蔽接地技术,有效防止LEMP的入侵;完善信息防雷保护,提高抗LEMP的能力。

| Abstract: | Hazards of the lightning electromagnetic pulse (LEMP)on informationization equipments have been expounded. The calculation and examples show that,the hazard of LEMP is inversely proportional to the distance of the lightning stroke spot and the probability N of lightning stroke is proportional to the square of the height h of the lightning stroke spot. The higher the N value is,the heavier the hazard of LEMP will be. Since LEMP is the keynote of lightning protection of informationization,shield grounding technology should be adopted to prevent from the intrusion of LEMP effectively,perfect the lightning protection of informationization and improve the capability of anti-LEMP. |
