摘　　要：分类介绍了高层建筑中雷电的破坏作用,结合工程实例对高层建筑电气设计中的防雷技术进行了初步探讨。其中,外部的防雷技术主要措施有设置接闪器+引下线+接地装置的外部防雷装置、均压环等,内部防雷措施主要是等电位连接、合理屏蔽、在线路关键节点设防雷保护器(SPD)等。此外,鉴于现今建筑物智能化趋势,从传统SPD系统出发,介绍了一种智能SPD系统,以及依托于此的智能防雷技术。Firstly,lightning damages in high-rise buildings are introduced,then lightning protection technologies in the electrical design of highrise buildings are discussed combing engineering examples. Among them,the main measures of external lightning protection technology is applying external lightning protection devices,including the lightning receptor-down conductor-grounding device system and lightning-proof equalizing ring. The internal lightning protection measures are mainly equipotential bonding,reasonable shielding,and setting lightning protection device(SPD) at key nodes of the line,etc.. In addition,in view of the current trend of building intelligence,starting from the traditional SPD system,an intelligent SPD system and intelligent lightning protection technology based on it are introduced.
