摘　　要：500 kV双回路紧凑型线路,导线采用"倒三角形"排列分别以"V"型绝缘子串方式对称布置在塔身两侧。铁塔结构形式新颖,杆塔导线横担悬臂较长。对紧凑型双回路直线塔结构特点进行了分析研究,根据其受力状况对结构进行设计优化和比较。最后,对一双回路紧凑型直线塔的真型试验结果进行了分析。In 500kV compact double circuit transmission line,the conducting wires are distributed with′inverted triangle′,and are laid on both sides of the tower body by the way of V insulator string.The structure formation of towers is very novel,and the cross arm is rather long.In this thesis the structure features of the straight-line tower in the compact double circuit are analyzed,then the structure is compared and optimized according to its being forced status.In the end,the real-model experiment results of a compact double circuit straight-line tower are analyzed.
