110kv 63mva High Voltage Rectifier Transformer 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. 110kv 63mva High Voltage Rectifier Transformer
