In order to achieve the above object, the utility model provides a kind of column amorphous alloy iron cores of three frame three, and the iron core is included：
First is unshakable in one's determination, and two second be wrapped in the first described iron core are unshakable in one's determination.
Wherein, if first described unshakable in one's determination and the second iron core is constituted by the folded dried layer amorphous alloy strips for setting.
Wherein, the window of two described the second iron cores is placed side by side and outer wall is close to, described two the second iron cores
Window is high equal.
Wherein, the first described cross section unshakable in one's determination and the second iron core is in semicircle shape or class semicircle shape, and the first iron core
The circular in cross-section shape or similar round shape fit together with the second iron core.
The width of the band of the first iron core described in constituting from the inside to the outside successively decrease by gradient.
Gradient is incremented by the width of the band of the second iron core described in constituting from the inside to the outside.
The width of the inner side band unshakable in one's determination of described first is equal to the width of the second outside band unshakable in one's determination.
Described first is unshakable in one's determination and the second iron core is equipped with a joining seam portion.
The joining seam portion unshakable in one's determination and the second iron core of described first is arranged on same one end.
The column amorphous alloy iron cores of three frame three that the utility model is provided, solve amorphous alloy transformer in the prior art
Anti- sudden short circuit ability than relatively low problem, with advantages below：
The cross section unshakable in one's determination is all rendered as circular configuration, is conducive to coil windings, can be pasted with iron core in coil windings
Tightly, the reaction between every layer line circle is born, support strength is enhanced, anti-short circuit capability is improve.

Specific embodiment
The technical solution of the utility model is described further below in conjunction with drawings and Examples.
As shown in figure 1, for the three-frame and three pole amorphous alloy that the utility model is provided is unshakable in one's determination, the iron core is included：First iron
The heart 10, and it is wrapped in two the second iron cores 20 in the first iron core 10.First unshakable in one's determination 10 and second iron core 20 sets by folded
If dried layer amorphous alloy strips are constituted, the end of the folded amorphous alloy strips for setting form respectively the outer wall and the of the first iron core 10
The outer wall of the inwall of two iron cores 20, the inwall of the first iron core 10 and the second iron core 20 is plane, can fit together.
The cross section of the first unshakable in one's determination 10 and second iron core 20 is in semicircle shape or class semicircle shape, and first unshakable in one's determination 10 and second
The unshakable in one's determination 20 circular in cross-section shapes or similar round shape for fitting together.
First unshakable in one's determination 10 and second iron core 20 is equipped with a joining seam portion 30, and the joining seam portion 30 is arranged on same one end.Such as
The schematic diagram of the cross section unshakable in one's determination shown in Fig. 4, above-mentioned class semicircle shape refers to the cross section of the first unshakable in one's determination 10 or second iron core 20
