| 摘 要： | 微风振动是高压输电线振动最普遍的形式,同时也是造成输电线路损伤的主要原因.本文根据实验场条件确定设计方案,设计出一种能模拟微风振动形式的实验装置.该装置通过改变导线的水平张力和线路的档距这两个控制变量,得到不同的固有频率,可用来研究架空线固有频率与档距、导线水平张力及导线单位长度质量之间的联系.

| Abstract: | The Aeolian vibration is the most common form of high-voltage transmission line vibration, which is also a main cause of transmission line damage. Based on the experiment field conditions, an experimental device is designed to simulate the aeolian vibration. By changing the wire horizontal tension and line span, these two control variables, the device can adjust to get different natural frequencies, then used to study the relationship between natural frequency and line span wire horizontal tension and traverse mass per unit length. |
