1000 kV 输电线路防振研究刘胜春,朱宽军,王�洪,刘超群( 国网北京电力建设研究院, 北京 100055)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。关键词: 特高压; 输电线路; 八分裂导线; 防振; 阻尼线; 防振锤中图分类号: T M75文献标志码: A文章编号: 1003-6520( 2008) 04-0638-05基金资助项目: 国家电网公司科技项目( SGSC[ 2005] 127) 。Project Supported by Research on Ant-i vibration and Ant-i gallo-ping of 1000 kV UH V T ransmission Line( SGSC[ 2005] 127) .Research on Ant-i vibration for 1000 kV UHV Transmission LinesLIU Sheng-chun, ZHU Kuan-jun, WANG Hong, LIU Chao-qun( Beijing Electric Pow er Construction Research Institute of SGCC, Beijing 100055, China)Abstract: This paper analyzes the factors influencing balance vibration of bundle conductor and proposes t he meas-ures to resolves t hem by corresponding steps on basis of elementary parameters of ant-i vibration test on UHV 8-bun-dle conductor system. A test method and condition of aeolian vibrat ion on UHV 8-bundle conductor w ere estab-lished. According to the parameters of the large crossing, the ant-i vibration devices test of 8-bundle conductor w ascarried, and the ant-i vibrat ion effect s about the tw o kinds of ant-i vibration devices, bat e damping w ire & dampersand pute dampers respectively, w ere compared. The two kinds of ant-i vibration devices can both meet the technical re-quirements, and the bate dampin...
