Description

Technical Field

[0001] This utility model relates to the field of iron core technology, and more specifically to a high-frequency transformer iron core. Background Technology

[0002] As a key component for energy transfer, the transformer core has undergone numerous technological innovations. Traditional cores use laminated silicon steel, utilizing the high permeability and low loss characteristics of cold-rolled grain-oriented silicon steel (CRGO) to reduce eddy current and hysteresis losses. In the mid-20th century, the emergence of amorphous alloy cores further reduced no-load losses; their disordered atomic structure significantly reduced the resistance to magnetic domain wall movement. However, their mechanical brittleness and high cost limited their widespread application.

[0003] Inadequacy of existing technology: The core of existing transformers is mostly positioned inside the transformer by a positioning device, and a large number of positioning bolts are required during positioning. Therefore, if the core is damaged or needs repair during the use of existing transformers, it is not convenient to remove and disassemble the core from the transformer. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-frequency transformer core to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-frequency transformer core, comprising a core assembly, wherein a first coil is installed in the middle of the outer side of the core assembly, and second coils are installed on both sides of the outer side of the core assembly.
