Research on 110 kV high-voltage lines crossing towers under specific environment

针对特定环境下穿越杆塔布置安全所存在的问题,提出了一种110 kV线路的双回路穿越杆塔的设计。杆塔设计基于对110 kV高压线路穿越的特定环境的分析和研究,采用水平与垂直混合型式杆塔结构,并在充分考虑杆塔的安全距离的前提对杆塔呼称高进行优化设计。通过将设计杆塔应用于实际工程并对不同工况下的杆塔监测数据进行了分析,证明该杆塔强度可靠,能够在设计荷载能够安全工作。

Aiming at the problems existing in the safety of arranging tower towers in a certain environment,a double loop loop tower design for 110 kV lines was proposed.The tower design was based on the analysis and study of the specific environment that the 110 kV high-voltage line traverses.It adopted a horizontal and vertical hybrid type tower structure,and optimized the call height of the tower in consideration of the safety distance of the tower.By applying the design of the tower to the actual project and analyzing the monitoring data of the tower under different working conditions,it was proved that the tower was reliable and able to work safely at the design load.
