ZHS Series Oil immersed Rectifier Transformer

Product Description

S

Specifications

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 : 400KVA 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.
