Application of Rectifier Transformer

Widely used in lighting, machine tools and electrical appliances, mechanical and electronic equipment, medical equipment, rectifiers and so on. The product performance can meet the special requirements of users.

I. ELECTROCHEMICAL INDUSTRY

This is the most widely used industry of rectification, electrolysis of non-ferrous metal compounds to produce aluminum, magnesium, copper and other metals; electrolysis of salt to produce chlor-alkali; electrolysis of water to produce hydrogen and oxygen.

2. DC power supply for traction

DC power grid for mining or urban electric locomotives. Because the valve side is connected with overhead lines, there are many short-circuit faults, and the DC load varies greatly. The locomotive often starts, which results in different degrees of short-term overload. For this reason, the temperature rise limit and current density of this kind of transformer are lower. The impedance is about 30% larger than the corresponding power transformer.

3. DC power supply for transmission

It is mainly used for DC motor power supply in electric drive, such as armature and excitation of rolling mill.

IV. HVDC transmission

The voltage of this kind of rectifier transformer is generally over 110 kV and its capacity is tens of thousands of kilovolt-amperes. Special attention should be paid to the overlapping of AC and DC insulation to the ground.

In addition, there are DC power supply for electroplating or electro-processing, DC power supply for excitation, DC power supply for charging and electrostatic precipitation, etc.
