摘　　要：针对500kV架空地线防振锤较易出现的滑移现象,分析了地线防振锤的结构特点、运行工况及无风有风力学模型,得出了架空地线防振锤出现滑移的原因为防振锤的受力特点、材料配对及地线蠕变伸长所致,从结构变更、材料选择等层面提出了4种防滑移改进方案,经综合对比最终确定最佳方案(方案1)并将其制成成品。有限元软件ANSYS Workbench仿真和防振锤定型试验结果表明,该方案符合使用要求,能够为地线防振锤滑移的运行维护工作提供一定的参考。For 500 kV overhead ground wire damper being prone to slipping phenomenon,this paper analyzed the structural characteristics,operating conditions and mechanical models of ground line dampers.The reasons caused ground line dampers tending to slip were obtained by studying the damper mechanical characteristics,the material pairing and the creep lengthening of ground lines.Four kinds of improvement programs was put forward considering the aspects of the structural changes and material selection.The optimal solution was determined and put into products.Analyzed by the finite element software ANSYS Workbench and verified by the damper technical specification test,the proposed program meets the actual requirement of power industry and provides a reference for the maintenance work to prevent the damper slip.
