ZS Series-Rectifier Transformer

Rectifier transformer is the power transformer of rectifier equipment. The characteristic of the rectifier equipment is that the primary side inputs AC, and the secondary side outputs DC after passing through the rectifier element.

ZYDQ ZS Series-Rectifier Transformer Description

Rectifier transformers are widely used in electrolytic electrochemistry, transmission, traction, electrostatic precipitators, DC transmission and other systems which need direct current power supply. Our rectifier transformer absorbed the excellent experiences of same industry at home and abroad. Raw materials such as high magnetic silicon steel sheet and high quality oxygen free copper wire are used. We adopt production technology such as advanced integral assembly per phase for windings, the core are laminated by five step-lap method to reduce iron loss and noise, crimped winding connections, precision machining for tank surface and so on, which make technologic performance at the leading level in domestic. We can design and manufacture various types of products according to user’s requirement.

 

Zs Series High Quality Voltage Rectifier Transformer Features

Rectifier transformer is the power transformer of rectifier equipment. The characteristic of the rectifier equipment is that the primary side inputs AC, and the secondary side outputs DC after passing through the rectifier element. Variable current is the general term for three working modes of rectification, countercurrent and frequency conversion. Rectification is the most widely used one. The transformer used as the power source of the rectifier is called a rectifier transformer. Most industrial rectified DC power supplies are obtained from the AC grid through rectifier transformers and rectifier equipment.

Rectifier transformer is a transformer specially designed for rectifier system.

Rectifier transformer function

1. Is to supply the proper voltage of the rectification system;

2. It is to reduce the pollution of the power grid caused by the waveform distortion caused by the rectification system.

The use of Oil Immersed Transformer

Widely used in lighting, machine tool electrical appliances, mechanical and electronic equipment, medical equipment, rectifiers, etc. Product performance can meet various special requirements of users.

1. Electrochemical Industry

This is the industry that uses the most 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 mine or city electric locomotives. Because the valve side is connected to the overhead line, there are many short-circuit faults, the DC load variation is large, and the electric locomotive often starts, causing short-term overload to varying degrees. For this reason, the temperature rise limit and current density of this type of transformer are both low. The impedance is about 30% greater than the corresponding power transformer.

3. DC power supply for transmission

It is mainly used to supply power to DC motors in electric drives, such as the armature and excitation of rolling mills.

4. For DC transmission

The voltage of this type of rectifier transformer is generally above 110kV, and the capacity is tens of thousands of kilovolt-amperes. Special attention should be paid to the AC and DC superposition of ground insulation.

In addition, there are DC power supplies for electroplating or electrical processing, DC power supplies for excitation, DC power supplies for charging and electrostatic dust removal, etc.
