Automatic deicing device for overhead transmission line

Abstract

The invention relates to an automatic deicing device for an overhead transmission line. The automatic deicing device comprises two deicing mechanisms, an advancing mechanism, a power mechanism, a control mechanism, a power supply module, an oil tank and an installation plate, wherein the installation plate comprises an upper installation plate, a middle installation plate and a lower installationplate, and the upper installation plate, the middle installation plate and the lower installation plate are connected through bolts from top to bottom; the advancing mechanism is installed on the upper end of the middle installation plate; the first deicing mechanism is installed on the front end of the middle installation plate and penetrates through a traverse; the second deicing mechanism is installed in the middle of the middle installation plate and is also connected with the power mechanism; the power mechanism and the control mechanism are both installed on the upper end of the lower installation plate; and the control mechanism comprises a video surveillance module installed on the upper installation plate, and a control cabinet installed on the lower installation plate. The deviceis reasonable in design, has a good deicing effect, can improve the power supply reliability of an electric power system, reduces the workloads of workers, lowers energy consumption, has a simple andpractical integral structure, has a stable working state, and is convenient in disassembling and repairing.

Description

technical field [0001] The invention belongs to the technical field of power transmission lines, in particular to an automatic deicing device for overhead power transmission lines. Background technique [0002] At present, there are more and more ultra-high and ultra-high voltage transmission lines. Due to the severe icing phenomenon of power grids in central China, east China and southern China, it will cause the towers carrying ultra-high and ultra-high voltage transmission lines to tilt, collapse and disconnection, and insulator flashover, which will cause tripping and power supply of transmission lines. Interruptions and other accidents have seriously affected industrial and agricultural production and people's lives. [0003] Due to the harsh and complicated working environment for line deicing, methods such as external force beating and high current melting are mainly used for deicing at home and abroad. The time consumption and cost are large, and the above methods ...
