Widely used in lighting, machine tools and electrical appliances, mechanical and electronic equipment, medical equipment, rectifier and so on. Product performance can meet a variety of special requirements of users.
One, the electrochemical industry
This is the application of the rectifier most industries, electrolysis of non-ferrous metal compounds in order to produce aluminum, magnesium, copper and other metals; electrolysis of salt in order to produce chlor-alkali; electrolysis of water to produce hydrogen and oxygen.
Two, DC power supply for traction
Used in mines or urban electric locomotives DC power grid. Due to the valve side of the overhead line, short-circuit faults, DC load changes in large spokes, the motorcycle often start, resulting in varying degrees of short-term overload. For this reason, the temperature rise limit and current density of this type of transformer are low. Impedance is about 30% larger than the corresponding power transformer.
Three, the transmission of DC power supply
Mainly used for power transmission in the DC motor power supply, such as rolling mill armature and excitation.
Four, DC power transmission
The voltage of such rectifier transformer is generally more than 110kV, the capacity in tens of thousands of kVA. Need to pay special attention to the ground insulation of AC and DC superposition.
In addition, there are electroplating or electroprocessing DC power supply, excitation DC power supply, charging and electrostatic dust DC power supply.
The rectifier equipment is characterized by the original side of the input current, while the secondary side through the rectifier original output DC. Variable current is a general term for the rectifier, countercurrent and inverter three modes of operation, rectifier is one of the most widely used. The transformer used as a power supply for the rectifier is called a rectifier transformer. Most of the rectified DC power supply for industrial use is obtained from the AC power grid through the rectifier transformer and rectification equipment.
