摘　　要：为了研究1000 kV特高压大跨越工程分裂导线防振问题,在特高压八分裂导线防振试验基本参数的基础上,分析了影响特高压子导线平衡振动的因素及采取的解决措施;完善了现有的试验设备并建立了特高压八分裂导线微风振动试验条件和试验方法。参照大跨越工程的有关参数进行八分裂导线防振方案试验,比较Bate阻尼线+防振锤型式和全防振锤型式这两种防振方案防振效果,试验结果证明,两种防振方案均能满足技术要求,从线路长期稳定运行的角度出发,建议采用Bate阻尼线+防振锤型式的防振方案。This paper analyzes the factors influencing balance vibration of bundle conductor and proposes the measures to resolves them by corresponding steps on basis of elementary parameters of anti-vibration test on UHV 8-bundle conductor system. A test method and condition of aeolian vibration on UHV 8-bundle conductor were estab- lished. According to the parameters of the large crossing, the anti-vibration devices test of 8-bundle conductor was carried, and the anti-vibration effects about the two kinds of anti-vibration devices, bate damping wire ＆ dampers and pute dampers respectively, were compared. The two kinds of anti-vibration devices can both meet the technical requirements, and the bate damping wire ＆ dampers should be recommended for the long-term and steady operation of lines.
