Iron core binding and winding method for secondary winding of current transformer

Abstract

The invention discloses an iron core binding and winding method for a secondary winding of a current transformer, and the method comprises the steps: binding an insulating buffer tape a on a magneticcore, wherein the insulating buffer tape a comprises a layer of paper board, a layer of semi-laminated twill tape, a layer of polyester board, a layer of semi-laminated polyester film, and two layersof semi-laminated PVC self-adhesive tape which are sequentially arranged from the inside to the outside; binding the insulating buffer tape b on the amorphous alloy core, wherein the insulating buffertape b comprises a layer of polyester plate, a layer of semi-laminated polyester film and two layers of semi-laminated PVC self-adhesive tapes which are sequentially arranged from inside to outside;uniformly distributing and winding secondary winding enameled round copper wires on the outer sides of the insulating buffer strip a and the insulating buffer strip b; and binding an insulating buffertape c on the outer side of the secondary winding enameled round copper wire. The method is convenient to operate, the performance of the iron core is fully guaranteed, the iron core cannot be greatly changed under the action of external force, the production quality and precision of the secondary winding are improved, and the product performance of the current transformer is further improved.

Description

Technical field[0001]The invention relates to a method for manufacturing a secondary winding of a current transformer, in particular to a method for wrapping and winding an iron core of the secondary winding of a current transformer.Background technique[0002]The current common winding methods for the secondary windings of current transformers are all reduced polarity windings, which can easily cause the magnetic cores of the secondary windings to be affected by external forces during winding, resulting in reduced product performance and failing to meet the requirements of national standards. The main reason is that the magnetic core of the secondary winding is subjected to external force, its performance has changed, and the enameled round copper wire for the secondary winding is not evenly arranged and wound on the magnetic core, resulting in uneven magnetic field inside the product, which increases the current The failure rate of transformer products.Summary of the invention[0003]...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the iron core is affected by external forces and the enamelled round copper wires are not evenly arranged, resulting in product performance degradation, and the accuracy of the secondary winding of the current transformer is too low during use, this application provides an iron core for the secondary winding of the current transformer.
