输电线路共享铁塔5G天线搭载高度及布置方式研究

架空输电线路铁塔空间分布广、数量多、搭载方便,具有与通信铁塔共建共享的天然优势。在分析5G移动通信基站天线结构型式的基础上,提出适用于搭载天线的共享铁塔选用原则;分析了输电铁塔天线搭载位置及影响因素,提出实用的天线布置及连接方式;研究了天线搭载高度与通信信号覆盖半径之间的关系,提出天线搭载高度的确定方法和共享铁塔最低呼称高的计算公式,计算得到110 kV,220 kV及500 kV输电线路共享铁塔的最低呼称高。相关研究成果普适性强,对我国输电铁塔的共建共享和5G通信组网具有很好的参考价值。

Research on 5G Antenna Mounting Height and Arrangement on Shared Tower of Transmission Lines

Transmission towers are characterized by wide spatial distribution,large number and convenient deployment,which means they have the natural advantages of co-construction and sharing with communication towers.Firstly,this paper proposes the shared towers selection principle based on the research of the 5 G antenna types;then it analyzes the antenna installation position and the influencing factors,and presents a practical antenna layout and connection mode;finally,it investigates the relationship between antenna mounting height and communication signal coverage radius and presents the calculation formulas of the minimum nominal heights of transmission line shared towers to conclude the minimum nominal heights of 110 kV,220 kV and 500 kV transmission line shared towers.The research result is universally applicable and has important reference value for co-construction and sharing of transmission towers and 5 G communication networking in China.
