Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] See ( figure 1 ), a folded three-phase transformer consisting of three core legs ( figure 1 ), the upper iron yoke and the lower iron yoke, the iron core columns have three vertical ones respectively, arranged at the three vertices of an equilateral triangle, such as ( Figure 4 ), the iron yoke is a connecting iron core connecting three iron core columns, such as ( figure 1 ) is divided into upper iron yoke and lower iron yoke. The axis direction of the iron core columns is connected in a star shape along the center line of the iron yoke. 120 degrees to each other in a plane.

[0034] Such as( figure 1 , image 3 , Figure 4 ), the iron core column is formed by stacking several iron chips vertically.

[0035] The iron yoke unit ( Figure 4 ) is formed by folding a number of core iron sheets horizontally.

[0036] The iron core post iron shee...

Abstract

The invention discloses a folding three-phase transformer which is a folding symmetric transformer, which is characterized in that an iron core is divided into three units along the center line of aniron yoke from the axis direction of the iron core, and the three units are respectively represented by A', B' and C'; one or more iron yokes are folded into 120 degrees in the length direction of theiron yokes, R arcs are arranged at the bent positions of the iron yoke iron sheets, the iron yoke iron sheets and iron core column iron sheets are folded into A', B' and C', and the three units are combined into a transformer iron core; inclined plane and trapezoidal connecting structures are adopted between the iron yokes and the iron core columns, so that lamination is facilitated, connection between the cylinders and the rectangular area is guaranteed, the problem that a three-phase symmetric transformer is difficult to manufacture is solved, and production of the three-phase symmetric transformer becomes reality; on the other hand, the symmetry of the three-phase transformer is achieved, the unbalanced loss of an iron core magnetic circuit and a circuit is reduced, the circuit harmonic amplitude is reduced, and the temperature of the transformer is reduced; and materials for the three-phase transformer are greatly reduced.

Description

technical field [0001] The invention relates to the entire power industry, and is a folded three-phase transformer and a manufacturing method thereof. Background technique [0002] The three-phase transformers currently used in the power industry are all in-line asymmetrical transformers. The main reason is that the manufacturing process of the three-phase symmetrical transformer is complicated and cannot be implemented. Contents of the invention [0003] In order to solve the problem that the manufacturing process of the three-phase symmetrical transformer in the background technology is complicated and cannot be implemented, the present invention provides a folded three-phase transformer and its manufacturing method, and the specific technical scheme is as follows. [0004] A folded three-phase transformer, comprising an iron core column and an iron yoke, the iron core column is formed by stacking several iron core column iron sheets; the iron yoke is formed by stacking...
