The invention discloses an iron core lamination structure of a current transformer. The iron core lamination structure of the current transformer is formed by laminating a plurality of laminates, wherein each laminate comprises two single laminate bodies which are matched with each other; the two single laminate bodies are assembled into a closed ring shape; one side of each single laminate body is provided with a plurality of convex parts; and a buckling groove is formed at the other side of each single laminate body corresponding to the convex parts. Positioning structures consisting of the convex parts and the buckling grooves are additionally arranged on the laminates of the iron core laminate structure of the current transformer; when iron cores are laminated, the iron cores are automatically laminated according to the specified number of the iron cores by virtue of special equipment; and compared with the prior art, a riveting or welding working procedure is canceled in the iron core laminate structure of the current transformer and high-quality and high-efficiency automatic production can be realized.
Description
technical field [0001] The invention relates to a current transformer, in particular to an iron core lamination structure of the current transformer. Background technique [0002] At present, the transformer is an important power detection device on smart appliances. With the continuous development of the smart grid, the precision requirements for various transformers are higher and the demand is increasing, especially those with a large amount of use and a wide range of applications. Low voltage transformer. Commonly used transformer cores are mainly laminated, and the assembly process is inefficient. Moreover, due to manual assembly, missing pieces often occur. If they are not found in time, it will cause failures such as power detection distortion. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide an iron core lamination structure of a current transformer, which can effectively solve the problems of low ...
