摘　　要：通过对传统重冰区输电线路单回路转角塔型的技术经济比较分析,提出了一种新型的水平排列莲花型转角塔.该塔型导线采用水平排列,中相导线跳线采用复合材料支撑铝合金穿管的形式从地线横担中间穿过,较好地解决了传统塔型在导线脱冰跳跃时防闪络能力差的问题.通过有限元分析软件对莲花塔进行了线性和非线性分析,结果表明,该塔型受力合理,结构稳定,过载能力好.Based on the technical and economic comparison of classic angle towers for single-circuit transmission lines in heavy ice areas, we propose a new type of angle tower named Lotus-tower. With the wire horizontal layout of the tower and the crossing of the mid-wire through the middle of two earth wire Crossarm by a tube of aluminum alloy with composite materials insulator, the Lotus-tower can enhance the ability of the prevention of the icing flashover. The paper also does a linear and nonlinear analysis of Lotus-tower by the FEM analysis software, the results showing that the structure of the proposed tower is rational, stable and safe.
