Description

High altitude cable defroster

Technical Field

The utility model relates to a high altitude cable maintenance technique, especially a high altitude cable defroster.

Background

As society demands electricity more and more, electricity becomes an indispensable part of life. In cold winter, a large amount of snow covers the high-voltage transmission lines in some areas, and the large amount of snow and the ice layer on the high-voltage transmission cables bring a large weight load, and often cause accidents such as tripping, wire breaking, pole falling, conductor waving, insulator flashover, communication interruption and the like of the lines, thereby causing great harm to the high-voltage transmission cables and the iron towers. Sudden shortage of electric power not only affects the economy but also brings great inconvenience to the lives of people.

At present, three cable deicing modes on a high-voltage transmission line are mainly provided, which are respectively as follows: short circuit electric heating ice melting method, mechanical ice removing and artificial ice removing. The key of the short-circuit electric heating ice melting method is to change the structure of the high-voltage cable and melt the ice layer by using a resistance heating mode, but by using the scheme, all the cables which can be frozen need to be replaced, and the long cable is heated, so that a large amount of energy is consumed, and the energy consumption and the cost are high. The manual deicing requires that power grid personnel continuously and manually beat, the danger elimination time is too long, and the unavoidable danger exists, and especially under the mountain area environment with dangerous terrain, the working risk of the power grid personnel is increased. Mechanical deicing is relatively flexible, energy consumption and cost are lower compared with short-circuit electrification, efficiency is higher compared with manual deicing, but at present, partial deicing machines are overlarge in size and mass, heavy, and inconvenient to install and maintain. Therefore, a mechanical deicing device with low energy consumption, simple structure and convenient installation and maintenance is needed.
