Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0030] The amorphous core is composed of a single frame or assembled from multiple frames. Single boxes are roughly rectangular. Specifically, the amorphous core can be a planar amorphous core, or a three-dimensional amorphous core. The single frames of the planar amorphous core are located on the same plane, and the single frames of the three-dimensional amorphous core are located on different planes.

[0031] As shown in the figure, the single frame includes a single frame base 10, and the single frame base 10 is formed by winding an amorphous strip material layer by layer.

[0032] An inner support frame 20 is provided inside the single frame base body 10 . One or more solidified layers 30 are provided on...

Abstract

The invention discloses a single frame of an amorphous iron core and the amorphous iron core. The single frame comprises a single frame substrate formed by winding amorphous strips layer by layer, one or more solidification layers are arranged on the surface of the single frame substrate, and at least the solidification layer on the outermost layer is a spraying type polyurea solidification layer formed by a polyurea material in a spraying mode. According to the scheme, by changing the forming mode and material of the curing layer, the performance of the amorphous iron core is improved, the excitation loss and noise of the amorphous iron core are reduced, and the strength of the amorphous iron core is improved.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a single frame of an amorphous iron core and an amorphous iron core. Background technique [0002] Compared with the same capacity amorphous core and silicon steel core, the no-load loss of the amorphous core is much lower than that of the silicon steel core. Therefore, more and more amorphous cores are used in the field of power equipment. [0003] The amorphous iron core is assembled by a single or multiple iron core single frames. The single frame of the iron core includes a single frame matrix, and the single frame matrix is ​​formed by winding an amorphous strip material layer by layer. The thickness of the amorphous strip is very thin and it is brittle after heat treatment. Therefore, during the stress relief process after heat treatment, the surface of the single frame substrate will undoubtedly be stressed and fragments will be generated. If the fragments are expo...
