【摘要】 电视台是宣传党和国家方针政策及百姓娱乐重要的信息工具,极易遭受雷电侵害。本文根据国家《建筑物防雷设计规范》〔GB50057-94(2000年版)〕等相关标准,对电视大楼进行了综合的防雷工程设计。电视台大楼楼顶卫星天线附近加三支避雷针防直击雷;对电源实行三级保护,在大楼五层总UPS前安装一套单相SPD;天馈线采用标准接口的气体管式避雷器;利用原有建筑物已构成的结构钢筋网组成法拉第笼式的整体屏蔽网为主要屏蔽网,接地利用建筑物的自然接地体,等电位连接网络主要有S型、M型和混合型三种。较好的保证了电视台正常工作。更多还原

【Abstract】 Television is a very important information and civilian entertainment tool,which gives wide publicity to the Communist Party of China and promotes the principles and policies of the country,and it is very vulnerable by lightning.In this paper,based on "Design code for protection of structures against lightning" GB50057-94(2000 edition),a comprehensive lightning protection engineering design for television building is given.In the roof of the TV stations building,three lightning conductors are put near the satellite antenna to prevent direct lightning flash,and the three-tier protection for the power is ensured.In front of the total UPS of the five-story building,a set of single-phase SPD is installed;the gas tube surge arresters with standard interface is taken as feeder-day;the faraday cage-like shield network is made up by structural steel net of the original buildings,which is mainly as a shield network;the natural building grounding is as grounding.The equipotential bonding network connections include category S,category M and mixed.These are better to ensure the normal work of the TV.更多还原
