Jumper upward-winding type composite cross arm drilling structure suitable for 750kV line
The invention relates to the technical field of power transmission line design, aims to solve the problem existing in drilling of a built line in the prior art, and provides a jumper wire up-winding type composite cross arm drilling structure suitable for a 750kV line. The jumper wire up-winding type composite cross arm drilling structure comprises a power transmission iron tower, and the power transmission iron tower comprises an iron tower cross arm and a ground wire support installed on the iron tower cross arm; the side-phase cross arms at the two ends of the iron tower cross arm are horizontally arranged composite cross arms; a horizontal jumper wire is hung at the end part of the composite cross arm, and the two ends of the horizontal jumper wire are connected with a first lead to realize the horizontal winding of the jumper wire; the ground wire support is connected with a jumper wire support, an upward-winding jumper wire is hung on the jumper wire support, and the two ends of the upward-winding jumper wire are connected with a second wire, so that upward winding of a middle-phase jumper wire is achieved; according to the invention, the height of the lead of the drilling tower can be effectively reduced by 7-11 m, the drilling difficulty is reduced, the reconstruction of the built line is avoided, the engineering cost is saved, and the normal operation of the drilled built line is ensured.
本发明涉及输电线路设计技术领域，旨在解决现有技术中钻越已建线路所存在的问题，提供一种适用750kV线路的跳线上绕式复合横担钻越结构，包括输电铁塔，所述输电铁塔包括铁塔横担以及安装在所述铁塔横担上的地线支架，所述铁塔横担两端的边相横担为水平布置的复合横担；所述复合横担的端部悬挂有水平跳线，所述水平跳线的两端与第一导线相连，实现跳线水平绕线；所述地线支架上连接有跳线支架，所述跳线支架上悬挂有上绕跳线，所述上绕跳线的两端与第二导线相连，实现中相跳线上绕；本发明可以有效降低钻越塔的导线高度7～11m，降低钻越难度，避免改造已建线路，节省了工程成本，保证了被钻越已建线路的正常运行。
