Multi-winding high-frequency transformer with solid insulation structure

The invention provides a multi-winding high-frequency transformer with a solid insulation structure, which is characterized in that an input coil is arranged close to a sectional magnetic core column,and a plurality of output coils are sequentially sleeved on the outer side of the input coil from top to bottom; and an upper magnet yoke and a lower magnet yoke are arranged on the upper side and the lower side of a shell type magnetic core and winding assembly respectively, and bypass magnet yokes are arranged on the outer side of the output coil respectively. Solid insulation filling structures are respectively arranged between the input coil and the output coil, between the input coil and the sectional type magnetic core column, and between the shell type magnetic core and winding assembly and the magnet yokes. A middle section magnetic core column is made of low-permeability magnetic materials, and the upper section and the lower section are both made of high-permeability magnetic materials.
