Modern Transformer Spares Maintenance is not Easy

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.
