Abstract

The invention relates to an overhead power transmission line electrification deicing device. The overhead power transmission line electrification deicing device includes an insulating deicing bar; the deicing bar is erected at one side of a power transmission line through a carrier frame; the carrier frame is provided with a driving mechanism; the carrier frame comprises two upright rods arranged in parallel; the two upright rods are positioned through at least two parallelly-arranged transverse rods between the two upright rods; the top end of each upright rod is suspended on the power transmission line through a suspending mechanism respectively; the deicing bar is vertically arranged on an end portion of a first transverse rod, wherein the end portion of the first transverse rod extends out from the upright rods; the height of the deicing bar is corresponding to the height of the top end of the upright rods; and the driving mechanism comprises a driving wheel and an insulating transmission rod wound on the driving wheel. The overhead power transmission line electrification deicing device of the invention is simple in structure. With the overhead power transmission line electrification deicing device adopted, deicing operation can be performed under a situation of electrification of a whole line, and the reliability and quality of power supply of a power system can be effectively ensured on the premise that the efficiency of the deicing operation can be improved.

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...
