摘    要:随着输电线路电压等级的提高,大截面导线、分裂导线的应用越来越多,风噪声和电晕噪声的问题日趋严重。导线风噪声是风吹过导线后,由导线表面的流体剥离所引起的压力变化所产生。在导线表面采取缠绕扰流线措施或直接使用低噪声导线,能够降低导线风噪声和电晕噪声水平。目前我国尚未开展防导线风噪声的研究。在我国输电线路飞速发展、特别是在特高压输电线路的前期准备工作中,应及时开展防导线风噪声的试验研究。

关 键 词:输电线路  导线风噪声  电晕噪声  扰流线  低噪声导线

Abstract:With increase of voltage grade for transmission lines large sectional conductor and bundle conductor have been used more and more and the wind noise and corona noise have become more serious gradually. The wind noise of transmission conductor has been produced by pressure variation caused by the fluid peeling on the conductor surface after wind blowing. The measures to disturbing the current by means of winding on the conductor surface or application of low-noise conductor can reduce the level of wind noise and corona noise. At present no research on wind noise proof for conductors has been carried out in China. It is necessary to implement test and study on wine noise proof of conductor in China in the early stage for preparation of EHV transmission lines.
Keywords:transmission line  conductor wind noise  corona noise  current disturbing wire  low noise conductor
