Abstract

The invention discloses a high-power rectifier transformer of a charger, and the high-power rectifier transformer comprises an iron core limb, and a primary side coil and a secondary side coil wound on the iron core limb. The high-power rectifier transformer is characterized in that the secondary side coil is formed by vertically winding a flat aluminum bar; the secondary side coil is divided into multiple layers of wire cakes; the wire cakes are separated by adopting insulating bakelite blocks; the secondary side coil is provided with two coil output ends and a plurality of intermediate taps; the coil output ends are arranged at two ends of the secondary side coil; the intermediate taps are arranged at the intermediate position of the secondary side coil; and output terminals are welded on the coil output ends and the intermediate taps. The high-power rectifier transformer has the advantages that the winding is convenient, the output terminals are welded more easily, the additional loss of the secondary side coil is small, the short-circuit-resistant mechanical strength is better, and the structure is compact. In addition, as the wire cakes of the secondary side coil are separated by utilizing the insulating bakelite blocks, not only is the insulation between the wire cakes achieved, but also the ventilation and the heat radiation of the secondary side coil are improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a high-power rectifying transformer for a charger. Background technique [0002] Rectifier transformers are often used in chargers. At present, the secondary winding of the high-power rectifier transformer used in the charger industry is a continuous or helical coil made of multiple insulated wires or transposed wires composed of multiple wires, a horizontal ventilation cooling channel and its outlet end. The existing technical problems are as follows: 1. Since the outlet end is welded with multiple wires and the outlet end, the welding is difficult and the process is complicated; 2. Due to the continuous winding of multiple insulated wires, The coil needs to be transposed and there is a horizontal ventilation and heat dissipation channel formed by a pad between the wire cakes. Therefore, not only the process is complicated, but also the coil structure is not compact; 3. Du...
