同塔多回路架空输电线路铁塔塔型研究

Study on types of multi-circuit towers

同塔多回路架空输电线路,可以减少架空输电线路的走廊数量,减少土地占用面积,具有良好的经济效益和社会效益。提出对铁塔的基本要求,对220 kV/110 kV、220 kV/35 kV、110 kV/35 kV等混合4回铁塔提出不同的结构型式,并进行计算分析,通过比较得出最优型式;分析了采用高强钢对结构的影响。

Since the multi-circuit tower can effectively reduce the corridors for overhead transmission lines and the occupied lands, it has good economic and social benefits. The basic requirements for the tower are proposed, as well as the four-circuit tower types for 220 kV/110 kV, 220 kV/35 kV, and 110 kV/35 kV lines. Through calculation, analysis and comparison, the optimal type was obtained. The influence of high-strength steel adoption on the tower structure is also analyzed.
