Three-phase transposition design structure of high-voltage long-distance overhead transmission line
The invention discloses a three-phase transposition design structure of a high-voltage long-distance overhead power transmission line, and relates to the technical field of high-voltage power transmission. An insulator is added on the basis of outgoing line insulators of two supporting parts of a lower cross arm of a strain iron tower, and the connection part between the two insulators is used as a supporting point of a jumper wire; in this way, two insulation supporting columns far away from the tension-resistant iron tower are not needed, the problem that an existing transposition mode occupies a large area is solved, and the three-phase power transmission line transposition device is suitable for transposition of the tension-resistant iron tower to the power transmission line.
本发明高压长距离架空输电线路的三相换位设计结构，涉及高压输电技术领域，通过在耐张铁塔的下横担的两个支撑部的出线绝缘子的基础上，再增加一个绝缘子，通过两个绝缘子之间的连接部位作为跳线的支撑点，实现三相输电线路的换向，以此，不在需要两个远离耐张铁塔的绝缘支柱，解决了现有的换位方式占地面积多的问题，本发明适用于耐张铁塔对输电线路的换位。
