rectifier transformer oil immersed transformer electrical transformer | |
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. |
8 | Losses: No-load losses is fully comply with IEC standard requirements. |
9 | Oil tank with various kinds of structure and good appearance. |
