Description:
Applied to transformers in the field, provides a three-phase five-column transformers, three-phase five columns described by a number of sub-three-phase transformer transformer combination of the five columns, each sub-phase transformers in three of the five sub-column single-phase transformer share two one next to the yoke; each sub-phase five-column magnetic transformer for the transformer described in three phases and five columns of a magnetic circuit unit, a number of sub-three-phase transformer magnetic circuit composed of five columns described in three phases and five columns of multi-magnetic circuit transformer structure; multiple sub-three-phase transformers in three of the five sub-column single-phase transformer combination of three single-phase transformer; above each column three winding transformer magnetic circuit by the wire in the vertical direction, each row in turn to wear around the single-phase transformer multiple magnetic circuit made of. The invention of three-phase five-column structure of a simple transformer, the transformer can reduce the volume to overcome the heat problem, reduce the overall loss of the transformer. Meanwhile, the simplified winding manufacturing process, reducing manufacturing costs, you can input and output high current.
