ZHS Series High Voltage Cathodic Protection Oil 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
