ZSSP Series 25kv 6300kva Electric Rectifier Transformator     Rectifier Transformer
1) Matching with intermediate frequency induction furnace
2) ISO9001,ISO14001,CE
 Main function and features   They are widely used in electrolysis, electrochemical , driving, traction , static de-dusting ,DC power transmission fields where rectification power source is necessary . 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. It is widely used in electrolysis , electrochemical , traction , driving ,DC transmission , frequency conversion and rectified power source fields. 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.      General   Rectifier transformers are combined with a diode or thyristor rectifier. The applications range from very large aluminum electrolysis to various small and medium size operations. 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.     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: 6~110 KV   2)    Capacity : 630 KVA to 120,000 KVA   3)    Short-circuit impedance : 4.5~21%   Losses: No-load losses is fully comply with IEC standard requirements     Application:   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.     ZSSP Series 25kv 6300kva Electric Rectifier Transformator
