Problems solved by technology

[0002] The traditional winding reel is not detachable. After the copper wire is wound into a coil, it is not easy to take it out from the winding reel. It needs tools to take it out. This operation is very inconvenient and laborious, which is not conducive to coil forming, and the traditional winding coil It is square, so winding is difficult, consumes more copper wires, and the winding efficiency is low

Abstract

The invention provides a wire wrapping method and a wire wrapping device of primary coils of a current transformer. The wire wrapping method comprises a cylinder portion and a wing portion. The cylinder portion is hollow and assembled by two half-cylinder parts, and screw holes are formed in the end face of the cylinder portion. The wing portion comprises two circular rings, the circular wings are assembled by two semicircular wing parts, a location hole is formed at connection of two semicircular wing parts, the inner circle radius of the circular rings is equal to the radius of the cylinder portion, screw holes are formed on the semicircular wing parts, and the wing portion is connected with two end faces of the cylinder portion via the screws. The cylinder portion and the wing portion are connected with each other through the screws, the coils are easy to be dismounted after the wire wrapping is finished, and time and energy are saved; an annular groove is arranged on periphery of the two end faces of the cylinder portion, and the half-cylinder parts are connected with the semicircle wing parts with junctions staggered, so that the wing portion is connected with the cylinder portion more tightly and wire wrapping device is more stable.

Description

technical field [0001] The invention relates to the field of transformer winding, in particular to a winding method and device for a primary coil of a current transformer. Background technique [0002] The traditional winding reel is not detachable. After the copper wire is wound into a coil, it is not easy to take it out from the winding reel. It needs tools to take it out. This operation is very inconvenient and laborious, which is not conducive to coil forming, and the traditional winding coil It is square, so winding is difficult, consumes more copper wires, and has low winding efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a convenient, labor-saving and material-saving winding method and a detachable and easy-to-operate primary winding device for current transformers. [0004] The technical solution of the present invention is: a w...
