Amorphous alloy iron core and amorphous alloy transformer

Abstract

The invention discloses an amorphous alloy iron core and an amorphous alloy transformer so as to adapt to external stress and effectively reduce noise variation. The amorphous alloy iron core comprises a base body formed by a plurality of layers of amorphous alloy material strips, and an oil film with a preset thickness is arranged between every two adjacent amorphous alloy material strip layers.The oil film thickness is preferably less than 10 [mu]m. By the adoption of the scheme, when the amorphous alloy iron core is subjected to external stress, the noise variation of the amorphous alloy iron core with the oil film with the preset thickness is remarkably reduced, the good noise reduction effect is achieved, and therefore technical guarantee is provided for wide application of the amorphous alloy iron core and full exertion of the excellent energy saving performance and economy of the amorphous alloy iron core.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to an amorphous alloy iron core and an amorphous alloy transformer. Background technique [0002] With the rapid development of industrial technology, the importance of energy saving and emission reduction has become increasingly prominent. Compared with silicon steel transformers, amorphous alloy transformers are both energy-saving and economical, in line with the requirements of national industrial policies and power grid energy conservation and consumption reduction, and are widely used due to their low no-load loss. [0003] As we all know, amorphous soft magnetic alloy material combines the advantages of silicon steel and soft ferrite, has high saturation magnetic induction intensity and extremely low iron loss, and can be widely used in iron core materials of various medium and high frequency power electronic equipment. It can effectively reduce the volume of the devi...

AI Technical Summary

Problems solved by technology

[0005] The existing amorphous material iron core generally adopts the method of brushing epoxy resin on the surface of the iron core for noise reduction treatment. When the resin filling between the belts is not dense enough, the amorphous material belts are easy to loose

Under the above circumstances, when the iron core is subjected to a certain external force, it is easy to generate vibration, and the change of noise is relatively large.
