摘　　要：为研究锚段关节等高点高度对受电弓通过锚段关节时接触线抬升量的影响,建立了2种不同等高点高度的含五跨锚段关节的接触网模型。计算了受电弓以不同的速度通过2种不同等高点高度的锚段关节时接触线抬升量并通过线路试验加以验证。研究结果表明,将锚段关节等高点高度从40 mm降低到20 mm可以起到降低接触线抬升量的效果,并且在隧道内或者隧道外、受电弓开口运行或者闭口运行时均具有良好的适用性。In order to study the influence of the contour heights of the overlap on the uplift of the contact wire when the pantograph passes through the overlap,two catenary models with five-span overlap with different contour height were established.The uplift of the contact wire are calculated when the pantograph passes through two types of overlap with different contour heights at different speeds,and verify it through line tests.The research results show that reducing the contour heights of the overlap from 40 mm to 20 mm can reduce the uplift of the contact wire,and it has good applicability inside or outside the tunnel,and in the knuckle-downstream and knuckle-upstream orientation of the pantograph.
