“双碳”导向共享铁塔塔型研究

A Study on"Dual-Carbon"Oriented Shared Tower Types

电力和通信共享同一铁塔可有效减少碳排放,有助于实现“碳中和、碳达峰”目标。通过深入分析通信设备安装、天线挂高、电力安全距离、电力输送等需求,提出了2种110 kV输电线路共享铁塔技术方案。基于质量、基底力及塔顶位移等指标的分析表明,2种方案均可满足通信及电力运维要求,而采用通信平台上置共享铁塔具有更好的经济性。基于需求能力比指标(DCR)开展结构优化计算,优化后塔型的总重减少了14.4%。

Using a single tower for both electrical and communication purposes can effectively reduce carbon emissions,contributing to the objectives of carbon neutrality and emission peak.Through in-depth analysis of communication equipment installation,antenna height,electrical safety distance,power transmission and other requirements,two alternative technical solutions suitable for the mutual usage of 110 kV suspension and tension towers are proposed.Analysis based on criteria such as mass,foundation forces,and tower-top displacements indicates that both designs meet the operational requirements of electric communication operation and maintenance,and the tower design with the communication platform positioned at the top presents superior economic benefits.Structural optimization calculations based on the Demand-Capacity Ratio(DCR)show that the optimized tower design reduces the overall weight by 14.4%.
