摘　　要：分析了非独立的直击雷防护系统中接闪器、引下线和接地装置与防雷击电磁脉冲的关系,阐述了独立的直击雷防护系统与防雷击电磁脉冲的关系。对于非独立的直击雷防护系统,适合的接闪器架设位置、增加引下线的数量可降低雷击电磁脉冲对电子系统的危害,B型接地装置可降低地电位反击对电子设备的危害。The relationships between lightning receptor,down lead,grounding device and lightning protection electromagnetic pulse were analyzed in direct lightning protection system.The relationship of direct lightning protection system and lightning protection electromagnetic pulse were elaborated.It was pointed out the suitable lightning receptor and the increasing number of down lead can reduce the harm of lightning electromagnetic pulse on electronic system,and the grounding devices decrease the harm of grounding potential counter on electronic system.
