Specific embodiment
It is with reference to the accompanying drawing and specific real in order to make those skilled in the art more fully understand technical solution of the present invention
Applying example, the present invention is described in further detail.
Without loss of generality, present embodiment is using stereo amorphous alloy wound iron core shown in Fig. 1 as basic description main body, in detail
Describe the bright transformer core technical solution with low noise in detail.It should be appreciated that the single frame size of the stereo amorphous alloy wound iron core
Where the not this Applicant's Abstract graph central inventive point of ratio, the limitation to the application core scheme is not constituted.
Referring to Figure 1, this shows the perspective view of stereo amorphous alloy wound iron core described in present embodiment.
The stereo amorphous alloy wound iron core includes three identical rectangular single frame matrixes 1, and each single frame matrix 1 is closed by amorphous
Golden material strip rolls to be formed.As shown, the frame side section of the single frame matrix 1 can be in semicircle shown in figure, three single frames
The munnion side of matrix 1 is fixedly connected sequentially, and the munnion side of adjacent single frame matrix constitutes stem, and heart column section is rounded；Correspondingly,
The transverse frame edge of each single frame matrix 1 is iron yoke.
Certainly, the frame side section of single frame matrix 1 is not limited to semicircle shown in figure, specifically can be according to concrete function
It is set, such as, but not limited to half of polygon, is consequently formed with polygon stem；As long as that is, obtaining
Good transformer core column performance is within the scope of the present application.
Wherein, the outer surface of each single frame matrix 1 is covered with buffer layer 3, and the amorphous which is formed in multistage coiling closes
Golden material strip outermost to fully absorb operating noise, and effectively mitigates the vibration of noncrystal substrate.Specifically, the material of the buffer layer 3
