The utility model provides a polycrystalline silicon variable-current dry-type transformer which comprises a three-phase iron core, a three-phase primary winding and a three-phase secondary winding, wherein the three-phase primary winding and the three-phase secondary winding are respectively sleeved on the three-phase iron core; each phase of secondary winding in the three-phase secondary winding comprises two groups of single-phase secondary split windings, and the six groups of single-phase secondary split windings are mutually independent and mutually insulated; and the upper part coil and the lower part coil in each group of single-phase secondary split windings are distributed at intervals in the radial direction of the iron core, are distributed at intervals in the axial direction of the iron core, and are connected in series through an external connecting wire. When the transformer is in a half-ride-through operation state and the transformer is in load operation, circulating current cannot be generat
