摘要
针对福州地区110 kV架空线路线路的耐雷水平较低问题,从降低线路绕击率的目的着手,提出了零保护角铁塔典型设计方案。重点讨论了铁塔典型设计中导线排列方式选择、防雷性能分析、铁塔结构优化等3个方面的设计问题,比较分析了该典型设计铁塔的综合技术经济指标。
Aiming at the lower lightning withstanding level of 1 lOkV overhead line in Fuzhou area, for the purpose of decrease the rate of shielding failure , a typical design scheme of steel tower with zero shielding angles was put forward. The selection of lead arrangement mode, the analysis of lightning protection performance and optimization of tower structure in the typical design were discussed emphatically, and the synthetically economic and technical target of the designed steel tower were compared and analyzed.
