Steel wire-lined hollow high-voltage bare conductor

Abstract

The present invention relates to a steel wire-lined hollow high-voltage bare conductor. The high-voltage conductor is made into a tubular structure; a steel wire is arranged at the center of the tubular structure; three-jaw brackets are arranged at every 150 mm to 1500 mm; and the steel wire passes through the centers of the brackets. The steel wire can increase the strength of the conductor, the wall of the tubular structure of the conductor can be thin, and the diameter of the tubular structure of the conductor is large, and therefore, the passing of hot air in the tubular structure of the conductor can be facilitated, the decrease of the loss of the conductor and the weight of the conductor can be benefitted by means of a skin effect; and the hot air can pass through the tubular structure of the conductor, so that the periphery of the high-voltage conductor can be heated, if rain, snow and freezing disasters occur, ice solidified on the conductor can be melt and falls off.

Description

technical field [0001] The invention relates to a high-voltage wire, in particular to a protection function for preventing open-air power equipment from freezing in freezing rain and snow disasters. Background technique [0002] At present, there is a hollow tubular high-voltage wire, the high-voltage wire is made into a tube, the diameter of which is between 5mm and 50mm, and the material is made of metals such as aluminum and copper. The middle of the pipe is connected to a three-way joint close to the transmission line tower, and through the three-way joint, it is connected to an air pump, and the air pump is connected to a hot wind generating source, and at least one opening in the whole pipe body is open to the atmosphere. Its working principle is: in case of freezing rain and snow accumulation, the high-voltage line tends to freeze. At this time, the air pump is started, and the air pump is connected to the source of hot air. The hot air flows into the pipe from the te...

Problems solved by technology

[0004] In order to overcome the disadvantages of the prior art that the wire strength requires the tube wall to be thick, so that the tube diameter is limited and cannot be too thick, so the ability to pass hot air is limited and the effect of melting ice is not good. The invention provides a lined steel wire hollow high voltage bare wire
