Rectifier Transformer              •Introduction to Products 1)  Rectifier transformers are widely used in electrolysis, electrochemical , driving, traction , static de-dusting ,DC power       transmission fields where rectification power source is necessary . 2)  A rectiformer is used for power supply of rectifying devices , most industrial DC power sources is transformed from an AC       network via rectifying devices consisting of a rectiformer and a rectify. 3)  It is widely used in electrolysis , electrochemical , traction , driving ,DC transmission , frequency conversion and rectified       power source fields. 4)  According to user’s requirements , the secondary winding phase difference can be designed to  30 ,15 ,7.5, for rectification      of  6-phase, 12-phase,24-phase and 48-phase.  5)  Rectifier transformers are combined with a diode or thyristor rectifier. 6)  The applications range from very large aluminum electrolysis to various small and medium size operations. 7)  The transformers may have a built-in or separate voltage regulation unit for direct output regulation of diode rectifiers , and       correspondingly a power factor improvement with a thyristor rectifiers.   •Main Function And Features     1)  Low loss  2)  Low noise 3)  High efficiency 4)  Low partial discharge 5)  Strong mechanical strength and short-circuit withstand ability . 6)  Operation reliability 7)  Easy maintenance  8)  Pretty outline and compact structure 9)  100% guaranteed no leakage   •Brief specification 1)  Voltage class: 6~110KV 2)  Capacity : 630 KVA to 120,000 KVA 3)  Short-circuit impedance : 4.5~21% 4)  Losses: No-load losses is fully comply with IEC standard requirements   •Application of Product 1)  Aluminum smelting 2)  Magnesium smelting 3)  Copper smelting 4)  Zinc smelting 5)  The largest installations are those for aluminum electrolysis with several transformer/rectifier units in parallel operation to       achieve the required DC current, in all cases the rectifier can be with diodes or thyristors.     Main Technical Parameters for 10kV~66kV Level ZS Series                 Oil-immersed self-cooled type rectifier transformer:
