The invention discloses a rigid contact net with the speed of 200 km per hour, and belongs to the field of key parameter optimization of rigid contact nets of rail transit. The rigid contact net adopts the following design and construction parameters: a pantograph with the speed of 200 km per hour, # imgabs 0 # span, 9.0 m staggered anchor section joints, an anchor section first suspension point raised # imgabs 1 #, an anchor section second suspension point raised # imgabs 2 #, and the rigidity of a wire clamp is pure rigidity. The construction deviation of the height of a contact line outside an anchor section joint is +/-5mm, the acceptance limit of the slope of the contact line is +/-0.1%, and the ratio of adjacent spans to the maximum construction limit value is 1: 1.25; the design and construction parameters of the method accord with related standards during actual operation, and the method has remarkable advantages.
本发明时速200km级刚性接触网属于轨道交通刚性接触网关键参数优选领域,本发明的刚性接触网采用以下设计和施工参数:时速200公里级别受电弓,#imgabs0#跨距,9.0m交错式锚段关节,锚段第一悬挂点抬高#imgabs1#,锚段第二悬挂点抬高#imgabs2#,线夹刚度为纯刚性,锚段关节外的接触线高度施工偏差±5mm,接触线斜率验收极限±1‰,相邻跨距比最大施工限值1:1.25;本发明的设计和施工参数在实际运行时符合相关标准且有显著优势。
