重覆冰山区陡坡220kV枪型酒杯直线塔设计研究

Design and Research of 220kV Gun and Cup Type Tower on Steep Slope in Heavy Icing Area

为了提高电网抗冰能力,基于某山区220kV架空输电线路工程运用220kV枪型酒杯直线塔,分别在绝缘配置、塔头间隙、脱冰跳跃、结构受力等方面进行了设计与分析,并对比了酒杯塔、猫头塔和枪型塔的塔头尺寸及造价,得出枪型塔经济性最优的结论。

In order to improve the ice resistance of power grid,based on a 220kV overhead transmission line project in mountainous area and using 220kV gun and cup type tower,this paper analyzes and introduces the design of 220kV gun cup type tower in terms of insulation configuration,tower head clearance,deicing jump,structural stress.By comparing the tower head size and cost of cup tower,cat head tower and gun and cup tower,it is concluded that the gun and cup tower has the best economy.
