Abstract
The utility model discloses a kind of transformer core, comprise iron core piece, the V-shaped folded angular surface of described iron core piece bending, 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.This transformer core, 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, has saved cost.
Description
Technical field
The utility model belongs to mechanical & electrical technology field, is 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.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and the transformer core that a kind of mechanical strength is high is provided.
For achieving the above object, technical solution adopted in the utility model 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 utility model also further provides a kind of transformer, and this transformer comprises aforesaid transformer core.
The beneficial effects of the utility model are: the transformer core that the utility model provides, and 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 utility model.
In figure, 1-iron core piece, 2-intermediolateral column, 3-back-up block, 4-sound arrester.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Transformer core of the present utility model 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 utility model, 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 execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
