Abstract:
A high-frequency transformer (1), comprises:a ring core (2) made of amorphous magnetic material;a core protection box (3) made of conductive material and enclosing said ring core (2);a high-voltage winding (4), consisting of enamel-insulated wire wound on said core protection box (3),characterized in that,the shape of said core protection box (3) is similar to that of said ring core (2), on a ring top wall (31) of said core protection box (3) there is a ring gap (32) in the peripheral direction, and at an inner fringe and an outer fringe of said ring gap (32), a plurality of leading wires (61, 62, 63, 64, 65, 66; 71, 72, 73, 74, 75, 76) electrically connected with said core protection box (3) are respectively arranged in the peripheral direction, said leading wires (61, 62, 63, 64, 65, 66) at inner fringe and said leading wires (71, 72, 73, 74, 75, 76) at outer fringe of said ring gap (32) are electrically-connected together respectively and form two terminals (60, 70), said core protection box (3) and said two terminals (60, 70) constitute a low-voltage winding of said high-frequency transformer (1).
