| 摘 要： | 风荷载对输电线路影响颇为广泛,输电线路架设为了减少风害影响,通常只考虑静态风荷载,不能准确反映风荷载对线路的影响。以某供电局500 kV线路风动实验数据为基础,研究不同风速,不同角度下风载对输电导线位移的影响,得出了动态风荷载下输电导线的位移变化情况。本研究成果可为输电线路防风设计、事故分析和防风校核等提供参考,对于深入风荷载在输电线路方面的研究具有重要意义。

| Abstract: | The wind load has a wide influence on the transmission line.The transmission line frame is set to reduce the wind damage effect.Usually,only the static wind load is considered,and the influence of the wind load on the line cannot be accurately reflected.Based on the experimental data of a 500 kV line of a power supply station,the effects of different wind speeds and wind loads on the transmission line displacement at different angles are studied.The displacement variation of the transmission line under dynamic wind load is obtained.The research results can provide reference for wind-proof design,accident analysis and wind proof check of transmission lines,and it is of great significance for deep wind load research on transmission lines. |
