Embodiment Construction

[0015] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0016] Such as figure 1 An amorphous alloy transformer core debris protection structure shown includes an iron core 2, a paper slot 1 arranged at the joint of the iron core 2, and a mesh cloth 3 binding the joint of the iron core 2; the paper slot is placed at the seam inside the iron core, and fixed on the iron core by adhesive tape; the mesh cloth is bound at the seam at the bottom of the iron core.

[0017] The structure first makes paper bin 1, such as Figure 2-4 As shown, the slot is formed from paper by two cuts and two folds; the formed slot has three folded edges and a groove that fits into the inside of the core ...

Abstract

The invention relates to a protective structure for amorphous alloy transformer core chippings. The protective structure comprises a core, a paper channel formed in the joint of the core and screen cloth for wrapping the joint of the core, wherein the paper channel is formed in the joint on the inner side of the core, and is fixed on the core through an adhesive tape; and the screen cloth is used for wrapping the joint at the bottom of the core. The paper channel on the inner side of the core in the invention can effectively prevent the amorphous chippings from flowing outwards, and the wrapping of the screen cloth reduces the generation of the amorphous chippings and prevents the chippings from flowing outwards. The amorphous alloy core is prevented from being stressed, and the product operation is more reliable and safer.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an amorphous alloy transformer core debris protection structure. Background technique [0002] Amorphous alloy transformers are mainly composed of coils, iron cores, clips, insulating parts, etc. Transformer cores are rolled from amorphous alloy strips. Since the thickness of the amorphous alloy strip is only 0.02-0.03mm, the strip is prone to breakage and deformation during shearing or assembly. After the amorphous alloy strip is made into a transformer core, since the amorphous alloy strip is very sensitive to mechanical stress, if the iron core is stressed during the assembly process, it is easy to cause the no-load loss and noise of the transformer to increase, so after the body is assembled Core debris cannot be reduced by bracing or binding. Through the dismantling inspection of the transformer, it was found that the debris mainly comes from the joints of the lower ...
