The invention relates to a contact net anchor section joint structure suitable for a high-speed railway with a speed of 400 kilometers per hour, which is characterized in that a first contact line and a first carrier cable of a first anchor section in a transition area are connected only through a dropper, and a second contact line and a second carrier cable of a second anchor section in the transition area are connected only through a dropper; according to the research of the inventor, after the elastic sling in the transition area is canceled, the current collection quality requirement between the pantograph and the catenary can still be ensured, the current collection quality between the pantograph and the catenary cannot be reduced, and more reasonable catenary elasticity is obtained by canceling the elastic sling at the suspension point of the transition span. The traditional cognition of the catenary industry is broken through, that is, better pantograph-catenary current collection quality can be achieved only by adding an elastic sling; no elastic sling exists in the transition area, interference between the elastic sling in the transition area and the cantilever is avoided, operation safety is improved, no elastic sling is arranged in the transition area, and purchase, installation and operation cost can be reduced.
本发明涉及一种适应于时速400公里高速铁路的接触网锚段关节结构,通过第一锚段在过渡区内的第一接触线和第一承力索之间仅通过吊弦连接,第二锚段在过渡区内的第二接触线和第二承力索之间仅通过吊弦连接,取消过渡区内的弹性吊索,根据发明人研究发现,取消过渡区内的弹性吊索后,依然可以保证弓网间受流质量需求,不会对弓网间受流质量造成降低,通过取消过渡跨悬挂点的弹性吊索,获取了更合理的接触网弹性,突破了接触网行业传统认知:“认为只有增加弹性吊索才能有更好的弓网受流质量”;且在过渡区不存在弹性吊索,进而避免过渡区内存在弹性吊索而与腕臂干涉,提高运营安全,且在过渡区内没有设置弹性吊索,可以降低采购、安装和运营的成本。
