Abstract
The invention discloses a transformer core which comprises an iron core part. The iron core part is bent to be a V-shaped fold angle surface, the included angle of the fold angle surface is 20-25 degrees, a sound insulation device is arranged on the outer portion of the iron core part, and a supporting block is arranged in the fold angle surface. According to the transformer core, by bending the iron core part into the V-shaped fold angle surface and arranging the supporting block in the middle of the fold angle surface, mechanical performance of the transformer core is improved, and consumables and costs can be reduced.
Description
Technical field
The invention belongs to mechanical & electrical technology field, be specifically related to a kind of transformer core.
Background technology
Iron core is magnetic circuit part main in transformer, and hot rolling or cold-reduced silicon sheet closed assembly higher by silicon content, that surface scribbles insulating varnish form conventionally.This transformer core, its mechanical strength is not high, and in the process of manufacturing, consumptive material is more, and the phenomenon of waste is very serious.
Summary of the invention
The object of the invention is, for above-mentioned the deficiencies in the prior art, provides the transformer core that a kind of mechanical strength is high.
For achieving the above object, the technical solution used in the present invention is as follows.
A transformer core, comprises iron core piece, the V-shaped folded angular surface of described iron core piece bending, and the angle of described folded angular surface is 20-25 degree, in the outside of described iron core piece, is provided with a sound arrester, in the inside of folded angular surface, is provided with back-up block.
Further, the bending part of described iron core piece is provided with intermediolateral column.
Further, described iron core piece, intermediolateral column and back-up block are one-body molded.
Further, described iron core piece is made by ultracrystallite material.
Further, the cross section of described iron core piece is oval or cylindrical.
Further, described intermediolateral column is made by iron silica magnetic particle core.
The present invention also further provides a kind of transformer, and this transformer comprises aforesaid transformer core.
The invention has the beneficial effects as follows: transformer core provided by the invention, by by the V-shaped folded angular surface of iron core piece bending and at the middle part of folded angular surface, back-up block is set, can promote the mechanical performance of iron core, and can reduce consumptive material, saved cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of transformer core of the present invention.
In figure, 1-iron core piece, 2-intermediolateral column, 3-back-up block, 4-sound arrester.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is described in further detail.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Transformer core of the present invention as shown in Figure 1, comprise iron core piece 1, the cross section of iron core piece 1 is oval or cylindrical, the V-shaped folded angular surface of this iron core piece 1 bending, the angle of folded angular surface is 20-25 degree, is provided with a sound arrester 4 in the outside of iron core piece 1, in the inside of folded angular surface, is provided with back-up block 3, the bending part of iron core piece is provided with intermediolateral column 2, and iron core piece 1, intermediolateral column 2 and back-up block 3 are one-body molded.As preferably, iron core piece 1 is made by ultracrystallite material, and intermediolateral column 2 is made by iron silica magnetic particle core.
Transformer core of the present invention, by by the V-shaped folded angular surface of iron core piece 1 bending and at the middle part of folded angular surface, back-up block 3 is set, can promote the mechanical performance of iron core, and can reduce consumptive material, has saved cost.By intermediolateral column is set, further improved the mechanical strength of this transformer core.By sound arrester is set, the noise that vibration can be caused excludes major part, can greatly reduce noise decibel.
The above embodiment has only expressed embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
