摘要
为了分析风速对导线张力的影响规律,针对性采取防护措施,分析了风速对导线张力的影响机理,并设置了基准工况,通过改变风速、档距及气温,计算分析不同条件下导线张力变化规律。结果表明,风速对导线张力的影响存在典型的分区效应,随着风速的增加,导线张力呈线性增长—非线性增长—急剧增长的变化规律,最后基于风速分区构建三级防风设计策略。
To analyze the influence pattern of wind speed on conductor tension and formulate targeted protection measures,this study delves into the mechanism through which wind affects conductor tension.A baseline operational scenario was established,and variations in wind speed,span length,and temperature were applied to calculate and analyze the patterns of tension change under different conditions.The results reveal a distinct zoning effect of wind speed on conductor tension:As wind speed increases,the conductor tension progresses through a phase of linear growth,transitions into nonlinear growth,and eventually undergoes a sharp escalation.Based on this wind speed zoning,a three-level wind-resistant design strategy is proposed.
