Rectifier transformer series overview

- Rectifying transformers are transformers that convert grid power into power required by rectifying equipment

-widely used in:
· The chemical industry (most used industry) electrolyzes nonferrous metal compounds to produce aluminum, magnesium, copper and other metals;

Electrolyzing salt to make chlorine-alkali;

Electrolysis of water to make hydrogen and oxygen

· DC power supply for traction, DC power grid for mine or city electric locomotives

DC power supply for transmission

· It is mainly used to supply power to DC motors in electric drive, such as armature and excitation of rolling mill

· For direct current transmission, the voltage of this kind of rectifier transformer is generally above 110kV, and the capacity is tens of thousands of kVA.

Special attention should be paid to the AC and DC superposition of ground insulation.

· Other applications include DC power for electroplating or electrical processing, DC power for excitation, DC power for charging and electrostatic dust removal, etc

- High reliability of operation verification in more than 50 countries and regions around the world

- Products are mainly sold to East Asia, Central Asia, Southeast Asia, South America, North America and other markets and regions

- Executive standard: IEC 60076 series

Rectifier transformer series FAQ

What is a rectifier transformer?
A rectifier transformer is a special type of transformer designed to provide optimized power supply for rectifier systems, converting AC voltage to DC voltage efficiently.
What are the main applications of rectifier transformers?
They are commonly used in industries such as electrolysis, metal smelting, chemical processing, and HVDC power transmission.
How does a rectifier transformer differ from a standard power transformer?
Rectifier transformers are designed to handle high harmonic content and provide stable DC output, whereas standard transformers primarily deal with AC power distribution.
What are the key features of a high-quality rectifier transformer?
Key features include low impedance, high efficiency, robust insulation, and the ability to withstand high harmonic distortion.
What types of rectifier transformers are available?
Common types include 6-pulse, 12-pulse, and 24-pulse rectifier transformers, depending on the required DC output quality.
How do I select the right rectifier transformer for my application?
Consider factors such as input voltage, required DC output, load characteristics, and environmental conditions.
What maintenance is required for rectifier transformers?
Regular inspections, oil testing (for oil-cooled units), thermal monitoring, and checking connections help ensure long-term reliability.
Can rectifier transformers be customized?
Yes, manufacturers often provide custom designs based on voltage, current, cooling method, and specific industry requirements.
What are the common cooling methods for rectifier transformers?
Cooling options include ONAN (oil-natural air-natural), ONAF (oil-natural air-forced), and dry-type cooling for certain applications.
How do I troubleshoot common issues with rectifier transformers?
Common issues include overheating, voltage fluctuations, and harmonics. Solutions may involve checking load balance, cooling systems, and harmonic filters.
