Stereo hybrid zero-clearance magnetic circuit three-phase transformer

Abstract

A stereo full-symmetric three-phase transformer is an important technical progress in the field of manufacturing of middle-and-large-sized transformers. The transformer can effectively eliminate voltage and current unbalance caused by asymmetry of a transformer magnetic circuit. On the basis of a stereo lamination type structure and a stereo winding type structure, the advantages of the two structures are complementary to generate specific structures, technical processing and manufacturing methods of another kind of serial iron cores and iron yokes of stereo structures, the characteristic of combining creativity and practicality is achieved, and the technology is mature. The transformer has the same market prospects as the stereo lamination type structure and the stereo winding type structure, and can be used in the industrial production field quickly.

Description

field of invention [0001] The invention belongs to the technical field of transformers in electricity, and relates to the magnetic circuit structure and manufacturing process of the transformer, in particular, it is a three-phase transformer with a large class of three-dimensional new structure and new technology. Background technique [0002] The basic principle of a transformer is to change one AC voltage to another through electromagnetic induction. Its basic structure is the cross-linking of circuits (including windings and external circuits) and magnetic circuits to change the AC voltage through mutual conversion of electric energy and magnetic energy. voltage. [0003] In the structure of the traditional high-power planar three-phase transformer, the magnetic circuit of the middle phase is short and the gap is small, while the magnetic circuit of the two side phases is long and the gap is large, resulting in the congenital asymmetry of the magnetic circuit structure of...
