Product Description

Specifications

ZHS Series Oil immersed Rectifier Transformer:Toroidal coil stucture, loss, Low noise, Low partial discharge, no leakage

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.

Certifications

Test lab
Testing are conducted for every transformer before delivery.Tests are classified to be routine tests and type test.

A - Routine tests: According to IEC 60076 standard , the following tests must be carried out for all units of the transformers
- Measurement of winding resistance .
- Measurement of voltage ratio and check of phase displacement.
- Measurement of short circuit impedance and load losses.
-Measurement of no-load losses and current .
-Dielectric routine tests including the separate source AC voltage withstanding test and short duration induced over voltage withstanding test ( ACSD ) .

B - Type tests :
The following tests shall be carried out
- Temperature rise test
- Lightning impulse test

C - Special tests :
- Determination of noise level according to IEC 60551 .
- Oil leakage test
- Overload test at 150 % rated current for one hour after temperature rise test ( top oil temperature rise and winding temperature rise must be measured and recorded in the report test also hot spot temperature rise must be calculated and recorded on the report test ) .
- Short Circuit Dynamic stability Test (test report from independent and accredited laboratory for similar transformer will be accepted).
