高压输电线路的导线换线施工

针对输电线路中常见的换线施工工艺做了一定的探索研究，解决了以往施工需将导线放到地面开断后人工回收，造成地面附着物损坏破坏环境的难题；全过程导线换线操作在空中进行，利用机械设备在线路两端牵放操作，旧导线在牵引场集中回收，对于跨越公路、河流、带电高压线路等本工艺优势明显，施工速度快，安全可控性强，节约人力资源，经济效果显著。

Replacement construction of high voltage transmission lines

The paper researches the common replacement technology in the transmission lines and solves the problems of the recovery to the conductor breaking in the construction, which lead to ground attachment damage to the environment. The replacement opera- tion is in the air during the whole process which uses the mechanical equipment to perform the pulling operation and recycles the old conductors in the traction field. The method has great advantages in the crossing highway, in the river and in the high - voltage line, which has the characteristic of fast construction speed, strong safety controlling, saves the human resources and has prominent eco- nomic effect.
