1. , the load tapchanging method of power transformer dynamic combined pressure regulation winding:

  • The former side'"'"'s pressure regulation of transformer, its winding is by a main winding and a plurality of with forming around the pressure regulation winding to, series connection, and each pressure regulation winding and two arm electronic power switches and a bridge electronic power switch composition brachium pontis formula pressure regulation unit is characterized in that;

    1}, the capacity of determining the pressure regulation winding, number;

    the capacity of each pressure regulation winding all do not equated to change into equate that all when the pressure regulation state was M%, the number of the pressure regulation winding of series connection was M-1 to the maximum;

    2}, determine the pressure regulation method of attachment of pressure regulation winding;

    the method for attachment that inserts several pressure regulation windings of pressure regulation work is that adjacent pressure regulation windings in series connects.
