Abstract
An on-load voltage regulating capacity regulating transformer comprises an iron core, coils and a support frame. The coils are three-phase. The on-load voltage regulating capacity regulating transformer is characterized in that an upper winding and a lower winding are arranged on the axial direction of the iron core of each phase coil. The structure of the upper winding is the same with that of the lower winding. The upper winding and the lower winding are sequentially provided with primary side voltage regulating coils, primary side main coils and secondary side coils from outside to inside. A primary side outgoing line of the primary side voltage regulating coil of the upper winding is connected with a primary side outgoing line of the primary side voltage regulating coil of the lower winding through a copper plate. The secondary coil of the upper winding is extracted by a secondary outgoing line and connected with an electric induction furnace. The secondary coil of the lower winding is extracted by the secondary outgoing line and connected with the electric induction furnace. The outgoing lines of the primary side main coils of the upper winding and the lower winding are respectively extracted and then connected with the copper plate of a voltage regulating coil. The on-load voltage regulating capacity regulating transformer has the advantages of being simple in structure, convenient to use, capable of simultaneously outputting various voltage and capacity by one transformer, saving installation space, reducing cost, guaranteeing stable operation of the electric induction furnace and solving problems existing in the prior art.
