浅谈高层建筑物的防雷与接地

高层建筑对防雷的要求很高，但是，由于各种因素的影响，高层建筑由于防雷系统安装不合理而造成危害的案例屡见不鲜，为此，提出高层建筑物防雷和接地的设计原则、高层建筑弱电系统接地的注意事项，并通过实例分析，说明高层建筑物电源系统的雷电与过电压保护；配电系统和UPS电源系统的防雷保护及其具体的防护措施；通信、网络系统的防雷与过电压保护；终端设备电源的防雷保护；接地系统装置的保护等。最后强调高层建筑物的防雷设计工作一定要执行国家相关标准，以期达到更好的效果。

On lightning protection and grounding of high-rises

High-rises have strict requirements on lightning protection;under the influence of various factors,however,they are often harmed because of irrationally installed lightning protection system.Therefore,this paper presents the design principle for lightning protection and grounding of high-rises as well as the points for attention in light-current system grounding of high-rises.Through case analysis,it expatiates on the lightning and overvoltage protection of high-rise mains system,lightning protection and specific measures of power distribution system and UPS system,lightning and overvoltage protection of communication and network system,lightning protection of terminal unit mains,protection of grounding system devices,etc.Finally,it is stressed that the design for lightning protection of high-rises should meet relevant national standards to achieve better results.
