摘要
为推进玻璃纤维增强树脂基复合材料（GFRP）在特高压交流工程的应用,依托锡盟—胜利特高压工程,针对上字型复合横担塔提出了电气、结构设计方案;开展了电场和结构有限元仿真分析;开展并通过了电气验证试验、真型塔结构试验以及构件拉压疲劳试验;提出了复合横担塔的工程施工和验收方案以及运维方案。通过经济性对比分析得出,与常规酒杯型角钢塔相比,复合横担塔可使呼高降低8 m、走廊宽度减少21.2 m、工程本体造价节约4%。
In order to promote the application of glass fiber reinforced polymer（GFRP） in UHV project, taking the Ximeng-to-Shengli UHV project as an example, we proposed the electrical and structural design schemes of GFRP cross arm suspension tower, and made the finite element analysis of electric field and structure. Then we carried out and passed the electrical verification test, the full-scale tower test, and the tension-compression fatigue test. Finally, we put forward an engineering construction and acceptance scheme, and the operational plan of GFRP cross arm suspension tower. Through economic comparison of the conventional steel tower, the height of proposed tower standard is reduced by 8 meters, the corridor width is reduced by 21.2 meters, and the project cost is reduced by 4%.
