Abstract

The invention provides line raising equipment for the live working of an electric transmission line, comprising at least one winding device (10) and an insulating strap, wherein the winding device (10) is provided with a fixing part which is fixed on the tower of the electric transmission line. One end of the insulating strap is in winding connection with the winding device (10), and the other end is connected with the phase line to be raised of the electric transmission line. The invention also provides a line raising method for the live working of the electric transmission line, comprising the step: the line raising equipment is connected with the phase line to be raised of the electric transmission line, wherein the line raising equipment comprises at least one winding device (10) and the insulating strap. One end of the insulating strap is in winding connection with the winding device (10), and the other end is connected with the phase line to be raised. The winding device (10) isused for winding the insulating strap to raise the phase line to be raised. The equipment has convenient transportation and carrying, and the method is convenient for the live working, reduces the working strength, and increases the safety of line raising.

Description

technical field [0001] The invention relates to a wire-lifting device and a wire-lifting method for live work of a power transmission line. Background technique [0002] At present, the live work of power system transmission lines has been carried out for more than 50 years, especially the live work of ultra-high voltage transmission lines has been carried out for nearly 30 years, which has brought safety and stability to the power system and brought huge benefits to the national economy. economic benefits. However, ultra-high voltage transmission lines are located in the mountains, and it is very difficult for maintenance workers to reach the line towers. Many places cannot be reached by ordinary vehicles, and only a small number of off-road jeeps or livestock can reach them. Such large, long tools and materials are difficult to reach. Near towers, transmission lines, or the labor intensity of workers is very high. However, in the past live working tools, due to the high ...
