摘　　要：为开发一种轻量化、结构性能稳定和耐久性的复合电杆,本文以沿海地区山地环境试点工程为背景,从输电电杆各种工况荷载计算入手,建立有限元分析模型,对复合电杆进行结构设计。以改性聚氨酯树脂为基体材料,以玻璃纤维为增强材料,通过小角度锥型缠绕工艺,制备一种上下两节的分段式结构12 m长复合电杆,开展了全尺寸电杆力学真型荷载性能评估及材料耐候等系列老化试验。结果表明,基于仿真计算制备的插接系数2.0的复合电杆在强度、挠度上满足实际工况应用需求,同时具有优良的耐候性。分段式结构电杆尺寸小,更轻质,将极大提高施工运输便利性,为配电网线路建设提供新思路。In order to develop a kind of lightweight,stable structure performance and durability of composite electric pole,this paper,based on the pilot project of mountainous environment in coastal area,starts with the load calculation of transmission electric pole under various working conditions,establishes the finite element analysis model,and carries on the structural design of composite electric pole.A 12 m long composite electric pole with two sections was prepared by small Angle cone-winding process using modified polyurethane as matrix material and glass fiber as reinforcement material.Mechanical true load performance evaluation and series of material aging test of the full-size electric pole were carried out.The results show that the composite pole with the insertion coefficient of 2.0 based on simulation meets the practical application requirements in terms of strength and deflection,and has excellent weather resistance.The segmented structure of the pole is smaller in size and lighter,which will greatly improve the convenience of construction and transportation and provide a new idea for the construction of distribution network lines.
