摘　　要：针对拟建荆门—武汉1000 kV特高压交流线路工程的王家滩汉江大跨越属于现有特高压交流大跨越工程中舞动设防等级最高的特点,结合大跨越工程实际设计参数及气象条件,从舞动等级划分、防舞装置选型、基于舞动稳定性机理的双摆防舞器结构参数的优化、防舞装置对导线弧垂的影响等方面进行分析和论证,提出可靠合理的防舞配置方案,同时设计了适用于工程所采用的6×JLHA1/EST-640/170型特强钢芯高强铝合金绞线的双摆防舞器装配图。In terms of the proposed Hanjiang large crossing of Jingmen-Wuhan 1000 kV UHVAC transmission line which is characterized by the maximum galloping intensity among the existing projects,this paper systematically analyses the classification of galloping level,selection of anti-galloping devices,structure optimization of antigalloping devices based on the galloping stability mechanism and the influence of anti-galloping devices on sag characters according to the specific design conditions of transmission line and climatic parameters.A reliable and reasonable anti-galloping scheme is proposed,moreover,a double pendulum anti-galloping device assembly drawing applicable to the type of conductor JLHA1/EST-640/170 with a splitting number of 6 is designed.
