Core and coil of triangular three-dimensional wound core transformer and assembly method for core and coil

Abstract

The invention discloses a core and a coil of a triangular three-dimensional wound core transformer and an assembly method for the core and the coil and belongs to the technical field of transformers. The core of the triangular three-dimensional wound core transformer comprises three single frame cores which are mutually spliced at an angle of 60 degrees, wherein the single frame cores are wound or folded by core plates with joints; the core plates with the large plate widths are arranged at the inner side of a single frame core window; the core plates with the small plate widths are arranged at the outer side of the single frame core window; and the plate widths of the core plates are gradually reduced from the inner side to the outer side of the single frame core window. The coil of the triangular three-dimensional wound core transformer is wound according to the shape of a cross section of a core column. The invention also discloses an assembly method for the core and the coil of the triangular three-dimensional wound core transformer. The core of the invention has lighter weight, the core material is saved, the core structure is simplified, the production manufacturability of the core is enhanced, the structure is more compact, and the anti-short circuit capability of the transformer is improved.

Description

technical field [0001] The invention relates to a triangular three-dimensional wound core transformer, more specifically, relates to a triangular three-dimensional wound core transformer core, a coil and an assembly method thereof. Background technique [0002] The triangular three-dimensional wound core transformer is a new structure transformer, which creatively reforms the laminated magnetic circuit structure and three-phase layout of the traditional transformer, so that the product performance is more optimized, and its advantages of saving materials and energy are becoming more and more outstanding. Everyone recognizes it, so its share in the State Grid bidding and user market is also increasing. [0003] The two core components of the triangular three-dimensional wound core transformer are the triangular three-dimensional wound core and the high and low voltage coils. The existing triangular three-dimensional wound core technology can be divided into two structural fo...

Problems solved by technology

However, the disadvantage of this method is that the production of the wound core is troublesome, and the consumables are relatively serious, which leads to the fact that the material and energy saving advantages of the triangular three-dimensional wound core transformer cannot be further expanded.
