Continuous dry-type transformer winding with free arrangement in radial direction and processing method thereof

The invention relates to the field of transformers, and provides a continuous dry-type transformer winding with free arrangement in the radial direction and a processing method thereof. The continuousdry-type transformer winding comprises an electromagnetic wire and an insulating inner cylinder, wherein the electromagnetic wire is wound on the insulating inner cylinder, the winding is a structurethat the electromagnetic wire is freely arranged in the radial direction and continuously wound on the whole in the axial direction, and the electromagnetic wire and the insulating inner cylinder areintegrally cast by resin. According to the winding method, the electromagnetic wire is wound from the winding starting end to the other side and is continuously wound on the whole in the axial direction, the electromagnetic wire is freely stacked on a winding die to form the radial height of the winding, and inter-layer insulation or inter-turn insulation is not required to be placed. According to the invention, the production efficiency is greatly improved, and materials are saved; meanwhile, the space occupancy rate of the wire in the winding is increased, the structure is simple, the winding is simple and convenient, the mechanical performance is good, the impact resistance is strong, the axial voltage gradient distribution is uniform, the inter-turn potential difference is small, thepartial discharge capacity is low, and the electrical performance is greatly improved.
