架空线微风振动架空线微风振动aeolian vibration of overhead line 之不能出现卡门气流旋涡。风速上限值随导线悬挂点离地面高度的增加而提高，通常达到8~10m/s。风向是振动持续稳定的必摇条件，当风向与导线轴线之间的夹角在450以上时.导线振动是稳定的，当此夹角在300~45’时，振动的稳定性很小，而当此夹角小于200时，一般不会发生振动. (3)档距长度。徽风振动以一个档距为独立的振动单元.档距愈大，由于档距长度等于半波长的整数倍的振动绷率值愈密集，故建立稚定振动的机率愈大，即振动持续时间增加。另一方面，风传输给导线的振动能t与档距长度成正比，这给大档距的防振设计带来很大困难。对于档距长度为10Om以下的小档距，不仅出现振动的机率很小，同时档距端部的阻尼作用对振动有很大的影响，故小档距一般不藉装设消振装盆. (4)导线张力.为了说明导线张力对振动的影响，引入了导线平均运行应力(通常用EDS表示)的概念，它是指年平均气沮及无外荷载条件下的导线水平应力，习惯上将此时导线张力值用导线极限强度(通常用UTS表示)的百分数来表示。提高导线张力会使导线本身的阻尼作用减小，并且导线的允许疲劳强度也随张力的提高而降低。因而提高导线张力增加了振动的危险性.国际大电网会议(CIGRE)根据各国提供的线路运行经脸进行总结，规定了一般情况下导线张力的上限值为25%UTS，这与中国根据线路的运行经验褥到的结论相同.另一方面，限制提高导线的张力必然会增加线路的建设投资。若将规定的EDS上限值作为一个绝对标准，而不考虑导线构造设计的差别，也会导致严重的振动后果，是不经济的。因此，正确地估价导线张力的影响，应从导线的阻尼作用来分析，例如结构设计相同而采用高强度材料制造的导线，应取用较低的EDS值，如果改变导线的结构设计而提高了阻尼作用，则可能取用较高的EDS值。自阻尼导线就是一种特殊结构设计的导线，其EDs值可提高到35%UTs左右，从而明显地降低了线路的造价，并解决了大跨越线档严重的徽风振动问题。 (5)惫垂线夹。虽然悬垂线夹对振动强度并无影响，但振动现象却是通过悬垂线夹转变为动态应力作用于导线的。实际运行经验说明，由于悬垂线夹的型式、性能及质t等方面的差异，或者由于安装使用不当，都会造成疲劳断股情况的极大差别。20世纪50年代曾一度认为悬垂线夹是防止导线疲劳断股的关键，企图设计一种“防振线夹”。基于这种观点研制成功了预纹丝型悬垂线夹，可以达到比较满愈的运行效果。现在对惫垂线夹的设计原则已充分考虑了徽风振动的特点，使各种常规的悬垂线夹已具有满意的防振性能。
