Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a laser-cut full-seam transformer iron core. Background Art

[0002] The fully-jointed transformer core is an important magnetic conductive material for the transformer. It can effectively guide the magnetic flux and form a closed magnetic circuit. When the transformer is working, the current passes through the winding to generate a magnetic field. This magnetic field is conducted and concentrated through the core, and then transferred to the winding on the other side to achieve the transmission and conversion of electric energy. It can effectively reduce the magnetic resistance in the magnetic circuit, reduce magnetic loss and iron loss, and improve the efficiency of the entire system. The choice of core is directly related to the working performance and loss level of the transformer.

[0003] When the transformer is working, there is an alternating current in the coil, and the magnetic flux it generates is of course alternating. This changing magnetic flux generates an induced current in the iron core. The induced current generated in the iron core circulates in a plane perpendicular to the direction of the magnetic flux, generating eddy currents. Eddy current losses also cause the iron core to heat up. In order to reduce eddy current losses, the transformer's iron core is stacked with insulated silicon steel sheets, so that the eddy current passes through a smaller cross-section in a long-shaped loop to increase the resistance on the eddy current path; at the same time, the silicon in the silicon steel increases the resistivity of the material, which also plays a role in reducing eddy currents. Therefore, to reduce the losses caused by eddy currents, it is necessary to ensure that the magnetic flux density of each part of the iron core is uniform;

[0004] The existing patent (publication number: CN204695930U) is a laser-cut full-seam transformer core. The laser-cut full-seam transformer core provided therein adopts a full-seam splicing method at the joints of the column pieces and the yoke pieces, which can increase the splicing area and thereby reduce the magnetic resistance on the splicing surface, effectively reduce the iron loss of the core, and at the same time reduce the noise generated by the core, thereby improving the efficiency of the core transformer.

[0005] In view of the above problems, existing patents have provided solutions, but the existing transformer core may generate noise and vibration and have poor performance.

[0006] Therefore, a laser-cut full-seam transformer core is proposed. Utility Model Content
