Assembled three-phase dry type transformer

The utility model relates to an assembled three-phase dry type transformer. The assembled three-phase dry type transformer comprises three single-phase dry type transformers which are independently placed and are electrically connected, wherein each single-phase dry type transformer comprises a primary winding and a secondary winding, the primary windings of the three single-phase dry type transformers are connected to form a D shape or a Y shape, and the secondary windings of the single-phase dry type transformers are connected to form a Y shape. According to the assembled three-phase dry type transformer, the three independent single-phase dry type transformers are adopted to form the three-phase dry type transformer, and the single-phase dry type transformers are small in size and weight compared with the integrated three-phase dry type transformer; when the assembled three-phase dry type transformer is applied to a high-rise or super high-rise building, the three independent single-phase dry type transformers are transported to a distribution room separately and then are assembled to form the integrated three-phase dry type transformer, both transporting and hoisting are convenient, and using is stable.
