Problems solved by technology

At present, in order to solve the problem of icing on transmission lines, deicing devices are usually used to clean the icing on transmission lines, but most of the existing deicing devices have the problem of incomplete ice cleaning, and the existing deicing devices pass Equipped with only one ice-crushing knife, when it encounters a heavily ice-covered cable, the ice-crushing knife may get stuck or rotate around the cable with the entire deicing device, which is prone to accidents

Abstract

The invention discloses a high-voltage cable deicing device for a distribution network, which includes a deicing unit, an advancing unit and a bearing unit. The deicing unit is set on the cable to perform deicing work, and the advancing unit is used to drive the deicing unit to move forward. , the carrying unit is responsible for connecting the deicing unit and the forward unit. The device of the present invention treats the ice in different areas through the first ice-crushing knife and the second ice-breaking knife, so the cleaning efficiency is higher, and the risk of knife jamming is less likely to occur, and the first ice-breaking knife and the second ice-breaking knife rotate in reverse, It can alleviate the torsion caused by crushing ice, making the device safer to use.

Description

technical field [0001] The invention relates to the technical field of distribution network, in particular to a high-voltage cable deicing device for distribution network. Background technique [0002] The icing of AC and DC transmission cables in winter is one of the biggest natural disasters in the power system. Rime is formed when cold raindrops fall on objects with a temperature below freezing. If it is condensed on the transmission line, it will form icing on the transmission line. For high-voltage cables for long-distance transmission, they usually rely on iron towers for support. Icing will increase the load on the iron tower. collapse. At present, in order to solve the problem of icing on transmission lines, deicing devices are usually used to clean the icing on transmission lines, but most of the existing deicing devices have the problem of incomplete ice cleaning, and the existing deicing devices pass Equipped with only one ice cutter, when it encounters a heavi...
