The rectifier transformer is a 2 × 3635-2562/2562 kVA one star and one delta single slot main transformer. Each transformer has dual star auxiliary and IPT between star points. High voltage 22kv, low voltage 0.267 V. The connection symbols are Yy0y6&Dy5y11. This transformer has 12 pulse outputs.
Rectifier transformer is a special form of multi-winding transformer, which is different from traditional multi-winding transformer: its low-voltage winding is divided into equal rated capacities by one or several windings. In power systems, the most widely used is the double-winding double-shunt transformer, which has one high-voltage winding and two shunt low-voltage windings. The rated voltage and capacity of each sub-winding are equal, and their total capacity is the same as the total capacity of the transformer.
