Embodiment Construction

[0022] In order to make the purpose and features of the present invention more comprehensible, the specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] See figure 1 , which is a schematic structural view of an amorphous alloy iron core provided by an embodiment of the present invention. As shown in the figure, the amorphous alloy iron core 100 includes an outer template 110 , an inner template 120 , and multiple stacks of amorphous alloy sheets 130 disposed between the inner template 120 and the outer template 110 . Wherein, the multiple stacks of amorphous alloy sheets 130 are separated by support sheets 140 , that is, support sheets 140 are provided between every two adjacent sets of amorphous alloy sheets.

[0024] In the above embodiments, a support sheet with a supporting function is placed in the amorphous alloy sheet, so that the external force resistance of the amorphous alloy ...

Abstract

The invention discloses an amorphous alloy transformer and an iron core of the amorphous alloy transformer and a manufacturing method of the amorphous alloy transformer. The amorphous alloy transformer iron core comprises an outer moldboard, an inner moldboard, a plurality of amorphous alloy pieces and supporting pieces, wherein the amorphous alloy pieces are arranged between the outer moldboard and the inner moldboard, and the supporting pieces are arranged between each two amorphous alloy pieces. External force resistant capacity of the amorphous alloy iron core is improved due to a supporting function of the supporting pieces, epoxy resin coated on the surface of the iron core is not prone to cracking or dropping due to stressing, and therefore noise of the amorphous alloy iron core is reduced effectively. Meanwhile, overall rigidity of the amorphous alloy iron core is enhanced, when emergency short circuit happens to the amorphous alloy transformer, the iron core is not prone to deformation, and reliability of operation of the amorphous alloy transformer is enhanced.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an amorphous alloy transformer, its iron core, and a manufacturing method. Background technique [0002] Amorphous alloy transformer is a new type of energy-saving transformer that uses a new type of magnetically conductive material—amorphous alloy to make an iron core. Compared with traditional transformers, its no-load loss is reduced by more than 70%, and its no-load current is reduced by about 80%. It is a distribution transformer with better energy-saving effect at present, and is especially suitable for places with low load rates such as rural power grids and developing regions. . [0003] The magnetostriction coefficient of amorphous alloy is relatively high, the vibration of amorphous iron core caused by magnetostriction is relatively small, the vibration magnitude is relatively large, and the corresponding noise is also large. How to reduce the amorphous alloy tran...
