Double-loop steel pipe tower overhead line straight pull-down structure
The invention relates to a double-loop steel pipe tower overhead line straight pull-down structure. The structure comprises a steel pipe tower, a cable terminal platform is installed at the lower portion of the steel pipe tower, and three layers of cross arms are installed at the position, located above the cable terminal platform, of the steel pipe tower. The uppermost cross arm is provided witha pair of upper-phase cross arms facing the left inclined rear part and the right inclined rear part respectively, and the middle-layer cross arm is provided with a pair of middle-phase cross arms facing the left side and the right side respectively; the lowermost cross arm is provided with a pair of lower-phase cross arms facing the left inclined front part and the right inclined front part respectively; and the end parts of the upper-phase cross arms, the middle-phase cross arms and the lower-phase cross arms are provided with suspension strain insulator strings which are used for suspendingan upper-phase downlead, a middle-phase downlead and a lower-phase downlead. The double-loop steel pipe tower overhead line straight pull-down structure is reasonable in design, novel in structure and high in practicability, the hanging point projection positions of the suspension strain insulator strings of the downleads of all phases fall near corresponding cable terminals, the leads can be directly led down, bending of the leads is reduced, electrical verification is convenient, machining is convenient, and the composite cross arm insulator breakage risk does not exist.
本发明涉及一种双回路钢管杆塔架空线路直拉引下结构，包括钢管杆塔，钢管杆塔下部安装有电缆终端平台，钢管杆塔位于电缆终端平台上方安装有三层横担；最上层横担具有一对分别朝向左斜后方和右斜后方的上相横担，中间层横担具有一对分别朝向左方和右方的中相横担；最下层横担具有一对分别朝向左斜前方和右斜前方的下相横担；上相横担、中相横担和下相横担端部均安装有用于悬挂上相引下线、中相引下线和下相引下线的悬垂耐张绝缘子串。本发明设计合理，结构新颖，实用性强，各相下引线的悬垂耐张绝缘子串挂点投影位置落于对应电缆终端头附近，可直接将导线引下，减少导线弯曲，电气校验便利，加工方便，不存在复合横担绝缘子断裂风险。
