500kV双回路换位塔跳线安装工艺研究

500kV Double Circuit Transposition Tower Jumper Installing Process Research

500kV双回路换位塔跳线安装工艺复杂,本文结合工程实际施工经验对其施工中的有关要点、难点进行总结研究。从施工前的准备工作,到组装跳线硬跳支撑杆、母线,提升硬支撑杆和跳串,安装各段跳线和间隔棒,液压耐张线夹等都进行了详细的说明。

500kV double circuit transposition tower jumper installing process is complicated. This paper combined with practical engineering experience, the relevant points and difficult points in the construction are summarized. From bar and bus, upgrading the pre-construction preparatory work, to assembling jumper hard jump support the hard support bar and hop string, installing jumpers and spacers, hydraulic pressuring strain clamp and so on are described in detail.
