Resin insulation dry-type transformer for wind power generation

The utility model discloses a resin insulation dry-type transformer for wind power generation, which comprises an A-phase winding, a B-phase winding and a C-phase winding. An iron core, a low-voltage insulated winding, an epoxide resin insulating cylinder and a high-voltage insulated winding are respectively arranged in each phase winding, wherein the low-voltage insulated winding, the epoxide resin insulating cylinder and the high-voltage insulated winding are sleeved outside the iron core sequentially; the axes of the low-voltage insulated winding, the epoxide resin insulating cylinder and the high-voltage insulated winding are all coincident with the axis of the iron core; and the iron core, the low-voltage insulated winding, the epoxide resin insulating cylinder and the high-voltage insulated winding are insulated mutually. By increasing the heights of transformation coils, a stack effect is formed for carrying out air draft and self-cooling; a long-term limit load capacity reaches 3.3MW; due to the adoption of an ultra-thin structure design, the thickness of the transformer is controlled in the range of below 1,300mm; and the severe conditions that the large capacity dry-type transformer is installed in a narrow space of a chassis of a fan tower frame are met.
