Aluminum-armored solid anti-ice high-voltage bare wire

Abstract

The invention relates to an aluminum-armored solid anti-ice high-voltage bare wire which is made to be in the shape of a tube. A steel wire is arranged at the center in the tube, and an insulating object is filled between the wall of the tube and the center. Due to the steel wire, lead strength is improved; due to a tubular aluminum armor, reduction of lead loss is facilitated. A current is added in an electric circuit formed by the aluminum armor and the steel wire, so that ice blocks can be thawn and shed.

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, known high-voltage transmission line insulators, circuit breaker insulators and other open-air power equipment will freeze when encountering freezing rain or snow disasters, which seriously threatens the safe operation of power equipment. [0003] With the advancement of technology, a high-voltage wire is made into a tube. There is a steel wire in the center of the tube, and a three-claw bracket is set every 150mm to 1500mm. The steel wire passes through the center of the bracket. The steel wire increases the strength of the conductor, and the pipe wall can be made thinner and larger in diameter, which is not only conducive to the passage of hot air in the pipe, but also conducive to reducing the loss of the conductor. The hot air in the...
