1000kV特高压输电线路组塔方案论证

Schemes Demonstration for Tower Erection on 1000 kV UHV Transmission Lines

针对1 000 kV特高压输电线路工程铁塔组立施工的关键问题,在分析借鉴超高压输电线路工程铁塔组立施工方法的基础上,提出了8种1 000 kV特高压铁塔组立方案。通过对8种方案优缺点、适用性、安全性的对比分析论证,确定了适用性、安全性较高的外拉线内悬浮大抱杆分解组塔方案,该方案将为今后特高压铁塔组立施工提供参考。

Eight tower erection schemes are proposed and used for reference on the basis of tower erection on 500 kV EHV transmission lines aiming at the key problems of tower erection on 1 000 kV UHV transmission lines. External-guyed and internal-suspended holding rod erection method is adopted after comparing the advantages, disadvantages, applicability and security of eight erection schemes. The scheme is a reference for the future tower erection on UHV Transmission Lines.
