一种采用组合绝缘子的输电线路杆塔
摘要：
本发明公开了一种采用组合绝缘子的输电线路杆塔，包括顺次连接的塔腿、塔身和塔头；还包括设置于杆塔侧面的至少一组由斜拉绝缘子和支柱绝缘子组成的组合绝缘子；所述斜拉绝缘子的一端与所述塔身连接，另一端与所述支柱绝缘子的一端连接，所述支柱绝缘子的另一端与所述塔身连接，其连接点位于所述斜拉绝缘子与所述塔身连接点的下方；所述支柱绝缘子与所述斜拉绝缘子连接的一端设有挂线金具。支柱绝缘子与塔身采用铰接，消除了导线不平衡张力对支柱绝缘子产生的弯矩和对杆塔产生的弯矩及扭矩，降低了对支柱绝缘子和杆塔的强度要求；在保证导线对地距离的前提下，本发明提供的杆塔结构降低了塔高，减小了导线荷载对杆塔的弯扭作用和杆塔基础荷载。
摘要（英）：

The invention discloses an electric transmission line tower using composite insulators. The electric transmission line tower using the composite insulators comprises tower legs, a tower body and a tower head, and further comprises at least one group of composite insulators which are arranged on the lateral side of the tower and are composed of a suspension insulator and a supporting insulator. One end of the suspension insulator is connected with the tower body, the other end of the suspension insulator is connected with one end of the supporting insulator, the other end of the supporting insulator is connected with the tower body, and the connecting point of the other end of the supporting insulator and the tower body is located below the connecting point of the suspension insulator and the tower body. One end, connected with the suspension insulator, of the supporting insulator is provided with a link fitting. Because the supporting insulator is hinged to the tower body, the bending moment, of the supporting insulator, generated by unbalanced wire tension and the bending moment and the torque, generated by the unbalanced wire tension, of the tower are eliminated, and requirements for the strength of the supporting insulator and the tower are reduced. On the premise that the clearance to ground of a wire is guaranteed, the height of the electric transmission line tower using the composite insulators is reduced, the bending and twisting affect of a conductor load on the tower and the basis load of the tower are reduced.
