1. Core Features: Key Designs That Differentiate from Traditional Transformers
Its core advantage stems from the revolutionary improvement in the core structure, which is completely different from the traditional laminated cores ("E" type / I type silicon steel lamination). Specifically, it can be summarized in three points:
(1)Core Manufacturing Process: High magnetic permeability silicon steel sheets are used, which are continuously wound into three 'single core frames' with exactly the same geometric dimensions through specialized equipment. These three single frames are then assembled into a triangular three-dimensional structure (instead of the traditional planar layout), ensuring that the entire core has no inter-layer seams.
(2)Magnetic circuit design optimization: The lengths of the three-phase magnetic circuits are completely equal and symmetrically distributed. The direction of the magnetic flux is fully aligned with the 'rolling orientation' of the silicon steel sheets (the direction in which the silicon steel has the highest magnetic permeability), effectively avoiding the additional losses caused by the magnetic circuit asymmetry and abrupt changes in magnetic reluctance at the joints in traditional transformers.
(3)Coil arrangement adaptation: The three-phase coils are arranged around the three 'edges' of the three-dimensional iron core in a '品'-shaped pattern, resulting in tighter coupling between the coils and the iron core.
