摘要(Abstract):

为加大复合材料在电网输电杆塔塔中的使用比例,针对典型设计条件,克服材料易变形的缺点,通过结构优化设计提高输电杆塔整体刚度,设计了220 kV全复合材料绝缘性输电杆塔。运用列举法推算出复合材料输电杆塔的壁厚和内部加肋厚度,确定典型220 kV全复合材料输电杆塔的优化结构。利用有限元法对复合材料输电杆塔结构进行力学校验,校验结果表明,设计的复合材料输电杆塔完全符合设计要求,可为220 kV全复合材料输电杆塔最终推广及应用提供参考。
To increase the proportion of composite materials used in the transmission tower of power grid, 220 kV composite insulated towers are designed following typical design conditions to overcome deformation proneness of materials and to improve the overall stiffness of towers through structural optimization design.Firstly, the wall thickness and internal ribbed thickness of composite towers are calculated by enumerating method, and the optimal structure of typical 220 kV composite towers is determined. Secondly, the finite element method is used to mechanically verify the structure of composite transmission towers, the result of which shows that the designed composite transmission towers are in conformity with design standards and can be employed as a reference to application and popularization of 220 kV composite transmission towers.
