Description

Technical Field

[0001] The utility model relates to the technical field of transformer core production, and specifically relates to a jig for detecting iron core production. Background Art

[0002] The structural design of the amorphous three-dimensional wound core is innovative and efficient. Its core structure is mainly made of amorphous alloy strips through a winding process to form a unique three-dimensional wound structure. This structure not only has no seams, but also has a balanced three-phase magnetic circuit, which helps to achieve efficient electromagnetic conversion.

[0003] Specifically, the main structure of the amorphous three-dimensional wound core is composed of triangular amorphous cores formed by combination. This design makes the overall structure of the iron core more stable and able to withstand greater electromagnetic forces. At the same time, three groups of evenly distributed combined coil structures are provided on the main structure of the amorphous iron core. This layout helps to achieve a uniform magnetic field distribution and improve the electromagnetic conversion efficiency.

[0004] In the actual production process, it is necessary to detect the size of the amorphous three-dimensional wound core, especially the outer diameter at the connection of the two combined coils. The traditional detection method mostly uses manual use of vernier calipers to measure at multiple angles, and then judges whether it is qualified according to the measured data. Such a detection method not only has uncontrollable human errors, but also is cumbersome to operate and needs further improvement. Summary of the Invention
