摘　　要：针对贵广高速铁路提速改造后,在接触网弹性吊索调整数量较多的锚段内,存在的弹性吊索张力超标问题,通过模拟仿真、现场试验等方法,分析弹性吊索张力变化规律,探索符合现场实际需求的张力调整方法。在接触线张力增加前提下,将弹性吊索张力及锚段内接触线高度等参数调整至符合相关标准要求,保障改造后良好的弓网匹配关系,提升供电设备运行品质。In response to the problem of excessive tension in the elastic stitch wires in anchor sections where a large number of the elastic stitch wires of the catenary are adjusted after the speed increase and renovation of the Guiyang-Guangzhou High-speed Railway,simulation modeling,on-site tests,etc.were used to analyze the changing trend of the tension of the elastic stitch wires,and a suitable method for adjusting the tension was explored to meet the actual needs on site.Under the premise of increasing the tension of the contact line,the tension of the elastic stitch wires and the height of contact wire within the anchor section were adjusted to meet the relevant standard requirements,which can ensure a good relationship between pantograph and catenary after renovation,and improve the operating renova-tion quality of the power supply equipment.
