Power transmission system and transposition method of power transmission line thereof
The invention relates to the field of power transmission line transposition, and discloses a power transmission system and a power transmission line transposition method thereof.The power transmission system comprises a power transmission line and a plurality of power transmission towers, and when the power transmission line is connected to an adjacent second power transmission tower from a first power transmission tower, the power transmission line is connected to an A-phase wire, a B-phase wire and a C-phase wire; any two wires with close spatial positions are in transposition connection at the second power transmission tower, and the remaining wire is a first in-place wire and keeps in-phase connection at the second power transmission tower; and when the power transmission line is connected to the adjacent third power transmission tower from the second power transmission tower, the first co-located wire and the other phase wire close to the spatial position of the first co-located wire are in transposition connection with the third power transmission tower, and the rest one phase wire is in in-phase connection with the third power transmission tower. The three-phase transposition operation of the power transmission line is carried out by adopting a method of transposition of two adjacent phases and no transposition of the remaining phase, an auxiliary sub-tower does not need to be arranged, and the problems of large occupied area, high investment and poor applicability in a traditional power transmission system are solved.
本发明涉及输电线路换位领域，公开了一种输电系统及其输电线路的换位方法，其包括输电线和多个输电塔，输电线自第一个输电塔连接至相邻的第二个输电塔时，在A相导线、B相导线以及C相导线中，空间位置相近的任意二者在第二个输电塔换位连接，且剩余一者为第一同位导线，在第二个输电塔保持同相连接；输电线自第二个输电塔连接至相邻的第三个输电塔时，第一同位导线以及与第一同位导线空间位置临近的另一相导线，于第三个输电塔换位连接，且剩余一者在第三个输电塔同相连接。本发明采用相邻二相换位，剩余一相不换位的方法进行输电线路的三相换位作业，其不需要设置辅助子塔，解决了传统输电系统中存在占地面积大、投资高及适用性差的问题。
