500 kV紧凑型双回路直线塔组立施工技术研究

Research on 500 kV Compact Double Circuit Straight-line Tower Erection Construction Technical

结合现阶段国内超高压线路工程紧凑型铁塔组立施工的相关研究,分析了国内首次研究开发的垂直排列的双回500 kV紧凑型输电线路工程铁塔的塔窗结构特点,从综合考虑铁塔组立施工方案可行性、安全性、经济性等要求出发,提出使用主副抱杆相结合的方案,以适用于500 kV紧凑型双回路直线塔组立施工。

Combined with the relevant research of domestic present Extra high voltage line project-compact double circuit straight-line tower construction, this paper analyzes the tower structure characteristics of the double circuit line 500 kV compact transmission line project. Based on the comprehensive consideration of the construction feasibility, safety and economy, it proposes the combination use of the main and secondary mounting pole, to apply to the 500 kV compact double circuit line straight tower construction.
