750KV single-loop full-cycle transposition tower
The invention relates to the technical field of power transmission line transposition towers, in particular to a 750 kilovolt single-loop full-cycle transposition tower. The device comprises a tower body, the top of the tower body is fixedly provided with the wire cross arm, the top of the wire cross arm is fixedly provided with the ground wire support, the top end of the ground wire support is fixedly provided with the left jumper frame and the right jumper frame respectively, the left end of the wire cross arm is fixedly provided with the left jumper frame capable of changing positions, and the middle of the wire cross arm is fixedly provided with the right jumper frame capable of changing positions. According to the invention, the structure is reasonable and compact, the use is convenient, through the cooperative use of the tower body, the left jumper frame, the right jumper frame, the left jumper bracket and the right jumper bracket, the phase sequence of the three-phase lead at the front and rear sides of the tower body is changed, a full-cycle transposition is completed, the characteristics of safety, reliability and small occupied area are realized, the operation is convenient, and the manufacturing cost is greatly reduced; and meanwhile, the electrical gap and the three-phase load unbalance degree both meet the design specification and the power grid operation requirements.
本发明涉及输电线路换位塔技术领域，是一种750千伏单回路全循环换位塔；其包括塔体；在塔体的顶部固定安装有导线横担，在导线横担的顶部固定安装有地线支架，在地线支架的顶端分别固定安装有左跳线架右跳线架，在导线横担的左端固定安装有能换位的左跳线支架，在导线横担的中部固定安装有能换位的右跳线支架。本发明结构合理而紧凑，使用方便，通过塔体、左跳线架、右跳线架、左跳线支架和右跳线支架的配合使用，改变了塔体前后侧的三相导线相序，完成了一个全循环换位，具有安全可靠和占地面积小的特点，方便了操作，大大降低了制造成本；同时电气间隙和三相负荷不平衡度均满足设计规范和电网运行要求。
