Balanced traction transformer winding construction of 220kVSCOTT

The utility model provides a balanced traction transformer winding construction of 220kVSCOTT, belongs to the traction transformer field of making for the railway. Draw forth T seat high voltage winding end and link to each other formation SCOTT transformer with M seat high voltage winding is terminal, the T seat is the transformer that the winding was placed perpendicularly, and the M seat is the transformer that the winding level was placed, this SCOTT transformer is the double -phase 227.5kV voltage of secondary side with the three -phase 220kV voltage transformation that once incline, and this double -phase voltage is at phase place allowance above nominal size 90, the SCOTT wiring pattern that adoption 220227.5kV secondary side mid point was taken out, T seat low voltage winding a1, a2, A3, a4 alternately establish ties, constitute T seat 27.5kV leading -out terminal T N1 and t N1, M seat b1, b2, B3, b4 alternately establish ties respectively, constitute M seat 27.5kV leading -out terminal M N2 and m N2.
