Problems solved by technology

If the two ends are directly butted at the junction, the iron core at the junction will be interrupted, resulting in a large magnetic resistance and affecting the transmission of magnetic flux. Therefore, it is necessary to improve the rectangular shape of the junction structure.

Embodiment Construction

[0008] see figure 1 and figure 2 , the present invention provides a butt-connected amorphous iron core with glue coating for noise reduction. The iron core sheets constituting the iron core are divided into several groups, the lengths of each iron core sheet in the same iron core sheet group are equal, and the two ends of the same iron core sheet group are butted with each other. A wedge-shaped micro-joint 1 is formed at the butt joint, and there is a certain distance between the micro-joints of adjacent iron core sheet groups in the tangential direction of the iron core, and glue coating 2 is coated on at least part of the front and rear end surfaces of the amorphous iron core.

[0009] The glue coating can cover all areas that do not need to be disassembled on the end face of the iron core, and can also cover the key parts that affect the overall strength and noise of the iron core. It can also be applied in strips to coat several connecting parts on the end face of the iro...

Abstract

The invention provides a butt amorphous core with noise reduction function of glue coating. The butt amorphous core is formed by a plurality of core plates. The core plates of one core plate group have the same length, the two ends of each core plate group are butted to form a micro seam, and the micro seams of different core plate groups have a distance with the micro seams of the adjacent core plate group along the tangential direction of the core. The glue coating is coated at least on part of the area of the front end surface and the back end surface of the amorphous core. The butt amorphous core of the invention can effectively prevent the magnetic resistance of the core at the bonding position from being increased greatly, ensures the transmission of magnetic flux, improves the property of the core, is beneficial to enhancing the intensity of the core and reducing the noise and is mainly used in corresponding amorphous transformers.

Description

technical field [0001] The invention relates to a glue-coated noise-reducing butt joint amorphous iron core, which can be mainly used for amorphous transformers. technical background [0002] In order to be able to put the coil on the amorphous core, usually at least one joint of its own should be set on the amorphous core, and a seam is left at the joint. From this joint, the amorphous core can be opened into a U shape, and the The snares are looped over the two arms of this U and then joined together after re-bending the ends of the U to form a rectangular core. If the two ends are directly butted at the junction, the iron core at the junction will be interrupted, resulting in a large magnetic resistance and affecting the transmission of magnetic flux. Therefore, it is necessary to improve the rectangular shape of the junction structure. Contents of the invention [0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a...
