Power transmission line cathead tower suitable for tower position with swing angle exceeding limit
The invention relates to a power transmission line cathead tower suitable for a tower position with a swing angle exceeding the limit. The power transmission line cathead tower comprises a tower body, a tower window and auxiliary cross arms at two sides. The tower window is arranged on the tower body and comprises a middle-phase cross arm and side-phase cross arms, the middle-phase cross arm is arranged at the top end of the tower window, a middle-phase I string hanging point is arranged on the middle-phase cross arm and used for being connected with one end of a middle-phase I-type insulator string, the other end is connected with a suspension yoke plate, the side-phase cross arms are symmetrically arranged at the two sides of the tower window, middle-phase inverted-V string hanging points are arranged at the positions, located on the side-phase cross arms at the two sides, of the inner side of the tower window respectively, and connected with one ends of middle-phase inverted-V insulator strings, the other ends of the middle-phase inverted-V insulator strings are connected with a suspension yoke plate, two side-phase I string hanging points are further arranged at the positions, located on the side-phase cross arms at the two sides, of the outer side of the tower window respectively and used for being connected with one ends of side-phase I-shaped insulator strings respectively, and the other ends are connected with a suspension yoke plate. Each auxiliary cross arm is provided with two side-phase inverted-V string hanging points, the side-phase inverted-V string hanging points are connected with side-phase inverted-V insulator strings, and the side-phase inverted-V insulator strings are connected with a suspension yoke, so that the size of the cathead tower can be reduced, and the engineering investment is reduced.
本发明是一种适用于摇摆角超限塔位的输电线路猫头塔包括：塔身；以及设置于塔身上的塔窗，塔窗包括：中相横担，设置于塔窗的顶端，中相横担上有中相I串挂点，用于连接中相I型绝缘子串的一端，另一端连接有悬垂联板，以及边相横担，对称设置于塔窗的两侧，两侧边相横担上的塔窗的内侧分别设置有中相倒V串挂点，连接并通过中相倒V型绝缘子串与悬垂联板连接，两侧边相横担上的塔窗的外侧还分别设置有两个边相I串挂点，分别用于连接边相I型绝缘子串的一端，另一端连接有悬垂联板；以及设置有两侧辅助横担，均设置有两个边相倒V串挂点，连接并通过边相倒V型绝缘子串与悬垂联板连接，使用本发明的猫头塔，可减小铁塔尺寸，降低工程投资。
