架空输电线路防风能力评估分析

Evaluation and Analysis of Windproof Capability of Overhead Transmission Lines

通过对沿海台风多发地区现有输电线路防风能力评估方法的探讨,以风荷载计算中的风荷载计算推导理论基础、导地线风荷载推导、绝缘子风荷载计算、塔身风荷载推导为标准,以结构验算中杆塔结构验算、杆塔结构基础连接验算为依据,给出了输电线路铁塔防风能力的明确计算方法,为后续新建线路和改造重要线路提供了评估方案和改造依据。

The article in view of the coastal areas for the typhoon,the existing transmission line windproof ability evaluation methods are discussed in this paper,by the wind load calculation of wind load calculation of theoretical basis,guide the ground wind load is derived,insulator wind load calculation,the towers are derived wind load is not standard and structure calculation of tower structure calculation,the structure of the tower foundation connection calculation basis,for transmission line tower,wind power,explicit calculation method is given for subsequent circuit and key circuit transformation provides a new evaluation scheme and transform the basis.
