摘　　要：为适应输电线路的发展,利用电绝缘复合材料对110kV电杆进行结构设计并作优化。针对材料本身的刚性不足变形较大的特点,提出了不同截面类型并作对比分析,选取了性能较好的适合FRP电杆的新型三角肋圆形截面。利用有限元Ansys软件对电杆进行三维实体建模,借鉴输电线路典型设计原则和钢管类设计条件,采用同结构、变尺寸的方法对模型施加荷载。参考输电设计规范,归纳分析出最优的结构形式及尺寸,电杆高为17m,直径为350mm,壁厚为10mm。为确保电杆运行可靠性,数值模拟了电杆在不同荷载工况下最大强度及变形,验证最大运行应力为109MPa,杆顶位移8.06cm。研究结果表明,这种分析方法设计出的电杆安全可靠,为复合材料电力应用提供理论支持。In order to adapt to the development of the transmission line, an electric insulating composite material is designed and optimized to the structure of 110kV power poles. The circular section with triangular rib is selected by comparing different types of sections of FRP poles to overcome the poor rigidity and the large deformation of the material. According to the design principles of the transmission line, a method called the same structure but variable size is adopted by applying a force on 3D solid model of the pole modeled by ANSYS. The most superior structure mode and dimensions are derived, in which the height is 17m, the diameter is 350mm and the thickness of the wall is 10mm. To ensure the reliable operation, the maximum strength and deformation under different conditions are simulated through numerical method. The maximum operation stress is 109MPa and the displacement of the top of the pole is 8.06cm. The results show that the pole design method is reliable and it provides theoretical support to use the composite materials in the electric power applications.
