摘要/Abstract

摘要： 基于输电线路实际工程,分别建立了四分裂导线风场模型和输电塔-线-间隔棒耦合模型,研究分裂导线气动特性和舞动响应受覆冰形状、覆冰厚度、风速和风攻角等参数的影响规律,明确导线与金具碰撞磨损机理。研究结果表明:各分裂导线间的气动特性存在较大差异,阻力系数受各参数的影响显著,随着覆冰厚度和风速的增加阻力系数逐渐增大;覆冰形式和覆冰厚度对升力系数的影响较小,风速和风攻角的影响较大;导线舞动过程中与连接金具发生了摩擦连续碰撞和瞬时强烈碰撞,导线最大接触法向作用力随风速增加而增大,随覆冰厚度增加而降低。本研究揭示了四分裂覆冰导线舞动特性规律和碰撞磨损机理,可以为输电线路防舞动设计和安全运营提供指导。
