Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] A live deicing device for overhead transmission lines, the structure of which is as follows figure 1 As shown, it includes a deicing stick 1, a carrier frame and a driving mechanism. The deicing rod 1 is arranged vertically on the power transmission line and is located on the side of the power transmission line, and is used to remove ice on the power transmission line; the carrier frame is used to carry the deicing rod, and the driving mechanism is used to drive the deicing rod to move forward.

[0029] A side view of the carrier frame as figure 2 shown. The carrier frame includes two vertical bars 21 arranged in parallel, and at least two horizontal bars arranged in parallel are positioned between the two vertical bars. In this embodiment, there are three horizontal bars in total. Wherein the first cross bar 22 is respecti...

Abstract

An energized deicing device for an overhead power transmission line, comprising an insulated deicing rod (1), wherein the deicing rod is arranged at one side of a power transmission line through a carrier bracket, and a drive mechanism is provided on the carrier bracket. The carrier bracket comprises two vertical bars (21) arranged in parallel, the two vertical bars being positioned by at least two cross bars (22, 23) arranged in parallel. The top end of each of the vertical bars is respectively suspended on a transmission conductor through a suspension mechanism (24). The deicing rod is vertically arranged at the end of the first cross bar (22) protruding from the vertical bar, and the height of the deicing rod corresponds to the top end height of the vertical bar. The drive mechanism comprises a drive wheel (31) and an insulating transmission rope (32) wound around the drive wheel. The deicing device has a simple structure, and can perform an energized deicing operation in the case where there is no power cut in the whole line, thereby effectively guaranteeing the reliability of power supply quality of an electric power system on the premise of improving the deicing operation efficiency.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a special equipment used in power transmission line operation. Background technique [0002] In power transmission and transformation projects, the phenomenon of icing on wires is common, and the faults caused by icing on transmission lines have seriously affected the normal operation of the power system. The icing of wires is a complex process, and the amount of icing is related to factors such as wire radius, supercooled water droplet diameter, air volume, wind speed, wind direction, air temperature, and icing time. The icing of transmission lines can cause conductor galloping, tower tilting, tower collapse, transmission line disconnection, insulator flashover and other hazards, further causing major accidents. [0003] At present, there are two main deicing methods applied to overhead transmission lines: 1) mechanical method, which can achieve the purpose of deicing by...
