输电线路上振动强度与风速关系的探究

The research on the relationship between vibration strength and the wind speed on the transmission lines

输电线路受风、雨、雷电等外界环境的影响,其中风灾害最为严重,风对输电线路的影响最为频繁且持续时间较长。输电线路由于受到不同风速的影响,线路上的信号也会发生变化,振动强度是衡量线路上振动信号强弱的物理量。本文采用选取不同风速情况下的实验数据,通过数据处理观察振动强度随时间的变化,分析对比不同天气下相应振动强度的变化规律。结果显示,输电线路上振动强度随时间变化趋势与风速随时间变化整体趋势一致,有着很强的线性相关性。

There are many factors influenced the transmission line, such as wind, rain, thunder and lightning etc, among of these, wind is the most serious. The influence of wind is the most frequent and a longer duration. The different wind speed can lead to different signal on the transmission lines, vibration strength is a physical quantity to measure the strong and weak of the signal. The experimental data under different wind speeds is selected in this paper, observing the change of vibration strength along with time, and analyze the change rule of the correspondin -g vibration strength under the different weather. The result show that the overall trend of vibration strength is consistent with wind, and a strong linear correlation between them.
