摘要
与普通导线相比,软铝导线具有节能、低弧垂、高载流、长寿命、性价比高等优点。本文重点研究软铝导线在220 kV输电线路设计应用上的技术规律,从振动疲劳、导线输送容量、电能损耗及温升、防晕等方面对比该导线与普通导线的性能差别,介绍了采用该导线对施工运行的影响。
Comparing with the ordinary wire,soft aluminum wires have the feature of saving energy,low sag,high current-carrying,long life,excellent cost performance,therefore this paper studys the technical rules of the soft aluminum wire applying on design of 220kV transmission lines,and compares the difference of performance between soft wires and ordinary wires in terms of vibration fatigue,transmission capacity,power loss and temperature rise,corona,etc.The paper also presents the influence of soft wires to construction and operation.
