THREE PHASE TRANSFORMERS, AND METHOD OF MANUFACTURING A THREE PHASE TRANSFORMER

摘要

a three-phase transformer, and mounting method of it are revealed. The three phase transformer comprises three closed loop magnetic center elements, each comprising two pairs of partial primary and secondary coils respectively associated with two different electrical phases of the three phase transformer. each pair of partial primary and secondary coils is placed on the same magnetic center section of its closed loop magnetic center element and its partial primary and secondary coils are respectively electrically connected in series or parallel to another primary and secondary coils. pair of partial primary and secondary coils associated with the same electrical phase and placed over another of the closed loop magnetic center elements. partial primary coils connected electrically in series or parallel are electrically coupled for connection to a three phase power supply. secondary coils connected electrically in series or in parallel are electrically coupled for connection to a three phase load.
