Summary:The utility model relates to a resin insulation stereoscopic iron rolling core dry-type transformer with a novel winding structure, which comprises three stereoscopic iron rolling cores, a low-voltage coil and a high-voltage coil, wherein the three stereoscopic iron rolling cores are fixed between an upper clip piece and an lower clip piece and are arranged in a triangular shape, and the low-voltage coil and the high-voltage coil are sequentially rolled on the stereoscopic rolling iron core. The resin insulation stereoscopic iron rolling core dry-type transformer is characterized in that an air passage is arranged between the low-voltage coil and the high-voltage, and an insulation tube is arranged in the air passage. Compared with the traditional technology, the resin insulation stereoscopic iron rolling core dry-type transformer has the advantages of few coil wires used, small volume, light weight, low manufacturing cost and low noise.
