Classification of special transformers

Classification of special transformers

According to the material, it is divided into: amorphous dry-type transformer, epoxy resin casting transformer, etc.;

According to the function, it is divided into: Scott transformer, 3-phase single-phase transformer, phase-shifting transformer, etc.;

According to the use, there are: UV mechanical transformers, spark transformers, dyeing and finishing mechanical transformers, rectifier transformers, transformers for energy-saving equipment, etc.

(1) Energy-saving transformer:

This series of energy-saving transformers is suitable for AC 50HZ, working voltage below 500V. The insulation and heat resistance level of this series of transformers is class F.

This series of energy-saving transformers are made of cold-rolled oriented high-quality silicon steel sheets.

(2) ZSG series rectifier transformer

It is widely used in industrial charging, DC lighting, DC excitation, electrolytic plating, electric drive, etc. ZSG series rectifier and transformer have the advantages of small size, light weight, simple maintenance and reliable operation.

(3) EPS, UPS special transformer:

EPS, UPS special transformer has the characteristics of high magnetic permeability and low loss, low noise, low temperature, radiation resistance and non-toxicity, maintenance-free, and high environmental protection. The special transformer has built-in high impedance, space efficiency and power conversion. efficient.

(4) QZB series step-down start-up autotransformer:

The autotransformer is used to reduce the power supply voltage to reduce the starting current, and at the same time, the starting current can be changed and the starting torque can be changed by selecting different taps of the autotransformer. Small, less impact on the machine when starting, short start time of the motor, usually used for 3-phase squirrel cage asynchronous motors below 320KW for infrequent starting and suspension of use.

(5) BK series control transformer

It is used as the power supply for control, lighting and indicator lights of machine tools and mechanical equipment in various industries.
