摘要: 在经济发达的城市地区,存在土地供应紧张与输电线路征地间的矛盾。基于以上问题,本文开发了一种类似火箭外形的复合材料绝缘窄基塔,导线从绝缘的复合材料塔内部穿过,最大程度地压缩线路走廊宽度,并对110 kV复合材料火箭塔的力学性能进行仿真计算及真型力学测试研究。研究结果显示:根开1.8 m,塔高19 m的110 kV的复合材料火箭塔通过了正常运行、断上导线、90°大风及不均匀覆冰等四个工况的100%设计荷载测试,复合材料杆塔各部杆件未见异常;其真型力学测试结果与杆塔的仿真计算结果高度吻合,其塔身最大变形均发生在火箭塔根部区域,对应的主杆最大变形均位于火箭塔根部区域;不均匀覆冰工况下,火箭塔的端部位移最大,最大位移量为48 mm,满足110 kV杆塔设计要求。

Abstract: In economically developed urban areas, there is a conflict between tight land supply and land acquisition for transmission lines. To solve the problem, this work research developed a composite insulating compact tower with a rocket-like shape, in which the wires pass through the inside of the insulating composite tower, compressing the width of the line corridor to the greatest extent. The mechanical properties of the 110 kV composite rocket tower were simulated and calculated, and truly experimental mechanical tested. The research results showed that the 110 kV composite rocket tower with a root opening of 1.8 meters and height of 19 meters had passed 100% design load tests under four operating conditions, including normal operation, disconnect the wire, 90° wind and uneven icing. There was no abnormality in all parts of the tower. The true mechanical test result was highly consistent with the simulation result of the tower, and the maximum deformation of the tower body occurred in the root area of the rocket tower, and the corresponding maximum deformation of the main rod was located in the root area of the rocket tower. Under the condition of nonuniform icing, the end displacement of the rocket tower was the largest, and the maximum displacement was 48 mm, which met the design requirements of the 110 kV tower.
