Abstract

The utility model discloses an iron core of an annular transformer, comprising a plurality of iron core blocks made of strip-shaped silicon steel plates with the width of 0.1 cm to 2.5 cm. The iron core blocks are overlapped and cemented to form an iron core. The iron core is widely applied to an annular transformer and has reasonable structure and low production cost.

Description

Ring transformer cores

Technical field

The utility model relates to a kind of ring transformer cores.

Background technology

At present, a kind of iron core that is applied in the toroidal transformer is arranged, this iron core is formed by banded silicon steel sheet coiling, the height of its iron core is consistent with the width of banded silicon steel sheet, usually the height of iron core is about 3～10cm, will cut at the height of required iron core when producing this banded silicon steel sheet, the feasible like this iron core cost of being produced is higher; And in various industries, also may need to cut out the silicon steel sheet or the silicon steel plate of various width, after finishing, cutting may remain the silicon steel sheet of some width between 0.1～2.5cm, these silicon steel sheets are generally the said clout of people, for these clouts, people handle as waste product, waste is bigger like this, in order to reduce the iron core cost and twice laid to be become the problem of the required discussion of people.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, ring transformer cores that production cost is low.

The technical scheme that its technical problem that solves the utility model adopts is:

Ring transformer cores comprises that the polylith width is the iron core cake that the banded silicon steel sheet coiling of 0.1～2.5cm forms, and these iron core cakes form iron core by stack and bonding back.

The beneficial effects of the utility model are: because the iron core cake that these iron core cakes are the banded silicon steel sheet coilings with 0.1～2.5cm to form is by stack and bonding postforming, effectively utilize the silicon steel sheet clout that is generated in the industrial processes process like this, also reduced the cost of iron core simultaneously.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a structural representation of the present utility model.

Embodiment

With reference to Fig. 1, Fig. 2, ring transformer cores comprises that the polylith width is the iron core cake 1 that the banded silicon steel sheet coiling of 0.1～2.5cm forms, and these iron core cakes 1 form iron core by stack and bonding back; Effectively utilize the silicon steel sheet clout that is generated in the industrial processes process by said structure, also reduced the cost of iron core simultaneously.

The utility model is rational in infrastructure, production cost is low, is a kind of iron core that is widely used in the toroidal transformer.

Claims

1. ring transformer cores is characterized in that: comprise that the polylith width is the iron core cake (1) that the banded silicon steel sheet coiling of 0.1～2.5cm forms, these iron core cakes (1) form iron core by stack and bonding back.
