Problems solved by technology

Even so, there are still certain deficiencies, such as: the position of the opening seam can only be concentrated on the upper end of the iron core column, which is very easy to cause loosening, shifting, and deformation, and the seam buried in the end of the coil is easily inserted. Installing the iron yoke brings great inconvenience, which not only affects the performance of the iron core, but also reduces the quality of the overall transformer

Embodiment Construction

[0024] In order to make the content of the invention clearly understandable, the present invention will be further described below in conjunction with the drawings and embodiments, but this does not constitute a limitation to the present invention.

[0025] specific implementation plan

[0026] See ( figure 1 ), the present invention includes an iron core 1, an upper iron yoke 2 of the iron core, a lower iron yoke 4 of the iron core, and three core posts 3 of the iron core.

[0027] See ( figure 2 ) section is oblong polygon 111 , polygon inscribed in a circle, rectangle 113 , and circle (R-shaped) 114 .

[0028] See ( image 3 ) ( Figure 4 ) ( Figure 5 ) ( Image 6 ) strip frame.

[0029] As an improvement of the technical solution, "a multi-purpose iron core manufacturing equipment" provided by the patent certificate No. 3472719 applied by me is adopted. It is characterized in that: the processed strip 1111 can be butted to have 8 135° or 12 Quasi-rectangular sili...

Abstract

The invention discloses a folding type planar three-phase open transformer core. The folding type planar three-phase open transformer core comprises a transformer core body provided with an L-shaped interlocking structure, wherein the transformer core body is assembled by two completely identical one-phase cores serving as inner rings and a large one-phase core serving as the outer ring, and the section of the assembled core body is in the shape of an inscribed polygon of a circle, or a circle (R type), or a rectangle or a long circle; a one-frame core is composed of a plurality of sets of rectangular open material straps arranged in a rectangular corner area, the butt joints of the openings of the material straps are located at the two ends of an upper yoke, the two bevels of the rectangle and the upper ends of two stems. The folded core stems and the yoke are interlocked, so that the mechanical strength of the core is improved. Therefore, the core has the advantages of being low in consumption, low in noise, high in sudden short circuit resistance and high in production efficiency.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a folded plane three-phase open transformer iron core. Background technique [0002] The transformer core is an important part of the transformer, and the types of transformers can be divided into single-phase transformers and three-phase transformers. In recent years, with the promotion of energy-saving products in the country, a detachable product with remarkable energy-saving effect has the advantages of light weight, small size, small no-load loss, simple manufacturing process, low noise, good energy-saving effect, strong heat dissipation and overload capacity. Folded planar three-phase open transformer cores with compact structure, superior mechanical and electrical properties are widely used. Even so, there are still certain deficiencies, such as: the position of the opening seam can only be concentrated on the upper end of the iron core column, which is very easy to ...
