Conducting wire deicing method and device for high-voltage transmission line

Abstract

The invention provides a conducting wire deicing method and device for a high-voltage transmission line. The conducting wire deicing device comprises a conducting wire walking robot, a rotating deicing device, a power device and a control device, wherein the conducting wire walking robot is driven by a fuel generator; the rotating deicing device is arranged on the conducting wire walking robot and used for removing ice coated on the conducting wire by rotating strike force; the power device is coupled with the rotating deicing device and used for driving the rotating deicing device to rotate; and the control device is used for controlling the movement of the conducting wire walking robot and the rotation of the power device. In the conducting wire deicing device for the high-voltage transmission line, a rotating strike rod, a vibration shock hammer and an ice scraping shovel are arranged on the conducting wire walking robot and simultaneously work to effectively remove the ice coated on the conducting wire by transverse shock, axial shock and axial extrusion.

Description

technical field [0001] The invention relates to the field of protection of transmission lines, in particular to a method and device for deicing conductors of high-voltage transmission lines. Background technique [0002] In winter, when the temperature is below 0°C, the transmission lines or towers will be covered with ice due to precipitation or snowfall. The icing of transmission lines seriously threatens the safe operation of the power grid. The consequences of power grid accidents caused by icing are very serious. In the slightest, the insulator strings will repeatedly trip due to ice flashes, and the deicing and jumping will cause conductor dance to cause short circuits between phases; in severe cases, it will cause serious damage to hardware and The wire is brittle and grounded, and the tower is tilted or even collapsed. [0003] my country is one of the countries with the most severe icing on transmission lines in the world. Severe icing will lead to a sharp decline...

AI Technical Summary

Problems solved by technology

Because the deicing device needs to be powered by batteries, the weight of the batteries and the continuous working time prevent this solution from being widely used

Moreover, this device will encounter great resistance when the ice is very thick, and it needs to provide a large driving force to move on the wire, so the deicing efficiency is low and the deicing speed is slow
