Problems solved by technology

Due to the on-site operation, the construction is difficult and the operation cost is high. Only partial winding can be carried out on the line, and the anti-icing effect is poor; and the aluminum foil cannot be evenly distributed, and it is easy to crack, which affects the electrical conductivity.
In addition, this kind of wire uses ordinary steel core as the reinforcement core, which is heavy, poor in strength, large in coefficient of linear expansion, easy to deform, easy to cause the wire to freeze, and affect the conductivity

Abstract

The invention provides an anti-icing wire and a manufacturing method thereof. The anti-icing wire comprises an inner carbon fiber core, annealed aluminum lines on the middle layer and the outer layer and low-Curie-point magnetic material wires coated with aluminum. The annealed aluminum lines on the outer layer and the low-Curie-point magnetic material wires coated with aluminum are distributed alternately. Each low-Curie-point magnetic material wire coated with aluminum is composed of an inner low-Curie-point magnetic material layer and an aluminum coating. The manufacturing method of the anti-icing wire comprises the steps that an aluminum rod is molten and extruded on the low-Curie-point magnetic material wires through an aluminum coating machine; a current generator is adopted for coating the inner low-Curie-point magnetic material layers with aluminum so that the aluminum coatings are formed; carbon fibers are used as the inner core, annealed aluminum wires are used as the middle layer and the outer layer, the low-Curie-point magnetic material wires coated with aluminum and the annealed aluminum wires on the outer layer are arranged alternately, and coaxial winding is conducted. The anti-icing wire and the manufacturing method thereof have the advantages that the construction difficulty and the operation cost are not increased, and the anti-icing wire is high in strength, light in weight, small in expansion linear coefficient, not prone to deformation and long in service life.

Description

technical field [0001] The invention relates to an anti-icing wire and a preparation method thereof. Background technique [0002] Ice galloping has always been an urgent problem to be solved for power grid transmission lines. The use of ferromagnetic materials with a low Curie point and the principle of electromagnetic induction of wires at low temperatures can effectively solve the problem of wire icing. At present, the spiral winding technology has been adopted, that is, the low Curie-point ferromagnetic material wire wrapped with aluminum foil is spirally wound on the wire wrapped on the wire, and the wire includes the steel core of the inner layer and the aluminum wire of the outer layer. Due to the on-site operation, the construction is difficult and the operation cost is high. Only partial winding can be carried out on the line, and the anti-icing effect is poor; and the aluminum foil cannot be evenly distributed, and it is easy to crack, which affects the electrical ...
