Rectifier maintenance involves
master practice and thus, such transformer spares maintenance is not easy as before. Modern range of rectifiers are
filled with electronic and sophisticated controls, programmable logic
controllers, power conversion devices, control equipment, and cooling systems.
To acquire a durable product, manufacturers make quality investment with several
hours of engineering, R & D, testing and maintenance practice. In order to
perform proper maintenance practice, one should have good understanding of the
type of rectifier system, type of control, hazards, and safety precautions.
Rectifier control types used in
the metal finishing industry are separated in following types and are available
in three phase and single phase power configurations.
No control – Such type of
rectifier offers limited output control and regulation. No control rectifier is
used at location where a single level of voltage is needed with limited
regulation.
Thyristor /SCR control
This is the most common type of
control used in modern metal finishing shop, where automatic control and/ or
remote operation are required. The SCR or thyristor is a solid semiconductor
device that acts as a switch, conducting when they are forward biased.
Transformer manufacturing
companies configure SCRs with one of two typologies for offering either primary
or secondary control rectifier control.
SMPS or Switchmode Power Supplies
Switchmode technology has been
used in smaller applications; however, since past 10 years, industry is able to
manufacture large components to allow power ratings for the metal finishing
industry. The manufacturers design these supplies in solid-state and
incorporate a high speed switching regulator.
The switch is either on or off.
Since the cost of copper
increased, these power supplies are cost effective due to the reduced copper
content. This technology provides inherent low loss conversion from AC to DC. Transformer
manufacturers are making these power supplies in ranges up to 10,000 amps in a
small, efficient, and reliable package.
Chopper
Chopper technology is the recent
one used by manufacturers for transformer applications to convert AC to DC.
This technology is used in large high current systems.
