输电线路增容改造设计的常见问题及其优化设计技巧

Optimization Skills for Common Problems in Capacity-increasing Transformation Design of Transmission Line

导线选型问题、更换增容导线后的杆塔荷载及摇摆角问题和原光缆的热稳定校验问题是输电线路增容改造的常见问题,这些问题与增容设计工作量和改造工程量直接相关。笔者对上述问题进行了归纳分析,提出了一些优化设计技巧,并结合工程实例证明了所提出的技巧有利于缩减增容设计工作量和改造工程量。

The common problems in capacity - increasing transformation of transmission line mainly include the selection of conductor, the tower load conditions, the swing angles and the heat stability verification of the original optical cable, which are directly related to the design and transformation working quantities. The paper proposes some optimization skills for the above problems, and proves that the proposed skills are conductive to reduce the design and transformation working quantities.
