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.

Transformer Characteristics
Traction Transformer for Oil-Immersed Three-Phase Two-Winding Transformer
Winding .
The winding must be especially protected - both against high electrical stress due to
external over voltages and against mechanical overloads by short circuits. They are made of copper or aluminum. Low-voltage windings are made of strip or flat wire while
high voltage windings are manufactured from round or profile wire. ("diamond-dotted paper") bonds the winding into a compact block
while drying and increases the short-circuit capacity additionally.

Magnetic Core lamination.
The three-limb iron core is made of oblique cut Grain-oriented, seven-step silicon steel lamination insulated on both sides,
guaranteeing low losses and low noise. These values are even improved by laser treatment. It is protected on the surface with a
flash-proof varnish in order to prevent the sheet from corrosion and to reduce the noise.

Oil tank.
Whether during transport or operation -the tank must be absolutely tight under mechanical stress. We have vast constructional experience, the most modern calculation methods and high-quality welding work. Special attention is paid to
corrosion protection. Pretreatment of the surface is processed by phosphating pickling, contributes to corrosion protection, just
like multi-coating with preset drying times for each layer. On request, hot-dip galvanization provides for even better protection

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
a- Measurement of winding resistance .
b- Measurement of voltage ratio and check of phase displacement.
c- Measurement of short circuit impedance and load losses.
d-Measurement of no-load losses and current .
e-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
a- Temperature rise test
b- Lightning impulse test

C - Special tests :
a- Determination of noise level according to IEC 60551 .
b- Oil leakage test
c- 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 ) .
d- Short Circuit Dynamic stability Test (test report from independent and accredited laboratory for similar transformer will be accepted).
