Abstract
An oil immersed stereo wound-core amorphous alloy transformer, comprising an iron core, a high-low voltage winding, leads and a tank. The core comprises three single frames made of amorphous alloy strips by winding and are identical in structure, and the single frames have a rectangular shape; the vertical sides of every two adjacent frames fit together fixedly to form a core pillar, and the horizontal sides of the single frame form iron yokes; the cross sections of the core pillars have an approximately circular or polygonal shape; the transformer further comprises a clamp, comprising a quasi-triangular upper and lower clamp, and posts, the lower clamp is provide with three food pads; the iron yokes in the lower portion of the iron core are located on the foot pads, and the high-low voltage winding is wound on the core pillars.
