Foreign matter removal method for overhead transmission lines

Abstract

The invention provides an overhead transmission line foreign matter removing method. The method is implemented by an overhead transmission line foreign matter removing device and auxiliary tools. The method comprises the steps of: 1, installing a lifting pulley; 2, installing auxiliary ropes; 3, lifting the overhead transmission line foreign matter removing device and enabling the overhead transmission line foreign matter removing device to be on a line; 4, dragging the overhead transmission line foreign matter removing device to the right place; 5, removing foreign matters; 6, turning off the power; and 7, withdrawing the device from the line. According to the principle of the method, a burn-red resistance wire is utilized to carry out hot cutting and removing on the foreign matters on the power transmission line. According to the invention, a power cut of the line is not needed, various kinds of foreign matters on the power transmission line can be removed clearly, effectively and thoroughly, the foreign matter removing efficiency is high, and the effect is good; in addition, the operation is convenient, time is saved, labor is saved and the work efficiency is improved.

Description

technical field [0001] The invention relates to a method for removing foreign objects in overhead transmission lines. Background technique [0002] Power transmission lines run in the natural environment for a long time, and it is easy to entangle foreign objects. For example, due to wind and other reasons, foreign objects such as agricultural greenhouse plastics, sunshade nets, woven belts, advertising cloths, kites and kite ropes are entangled in the power transmission line. On the line, after these foreign objects are exposed to rain or moisture, the insulation performance is poor, and it is easy to cause accidents such as tripping and short circuit of the transmission line, which seriously affects the safety of power supply of the power grid. The traditional method of removing foreign objects in the transmission line is to have the operator hang the flying car on the transmission wire under the premise of a power outage, and then sit on the flying car and move to the for...

AI Technical Summary

Problems solved by technology

At present, there are usually two types of foreign matter removal methods for overhead transmission lines: one is to use an insulating operating rod plus various cutting and pulling cutter heads set on the insulating operating rod head. The operator holds the insulating operating rod and uses various The cutter head cuts and pulls the foreign matter on the line to remove the foreign matter, such as the authorized announcement number CN 202423996U, the authorized announcement number CN 202034707, the application publication number CN 104064985A and other Chinese patent documents; the common disadvantage of this type of device is the operation comparison Time-consuming, labor-intensive, inefficient, and difficult to deal with foreign objects on lines that are far away from pole towers; the other type is to install various cutter head-type rescue tools on devices that can move on transmission lines to remove foreign objects, such as The application publication number is CN 103441448A, the application publication number is CN 103944108A and other Chinese patent documents; it solves the problem of the first type of device that is difficult to deal with foreign objects on the line that is far away from the tower through the device that can move on the transmission line. problems, but this type of device still relies on various cutter heads to remove foreign matter on the line by cutting, and there are still problems such as the first type of device is not efficient in removing foreign matter, and the effect is not good.
