Common five transformer classifications

Many people who don't understand the transformer don't understand the classification rules of the transformer. They only know the amorphous alloy oil-immersed step-down transformer and the three-phase dry 500kva transformer. They don't know the classification principle. Today, we will explain the classification of common transformers in detail. .
General transformers are often divided into five categories:
I is divided by phase:
(1) Single-phase transformer: used for single-phase load and three-phase transformer group.
(2) Three-phase transformer: used for the rise and fall voltage of the three-phase system.
II is divided by cooling method:
(1) Dry-type transformer: It relies on air convection to cool, and is generally used for small-capacity transformers such as local lighting and electronic circuits.
(2) Oil-immersed transformer: rely on oil as cooling medium, such as oil-immersed self-cooling, oil-immersed air-cooled, oil-immersed water-cooled, forced oil circulation, etc.
III by purpose:
(1) Power transformer: used to increase and decrease the voltage of the transmission and distribution system.
(2) Instrument transformers: such as voltage transformers, current transformers, measuring instruments and relay protection devices.
(3) Test transformer: It can generate high voltage and carry out high voltage test on electrical equipment.
(4) Special transformers: such as electric furnace transformers, rectifier transformers, adjusting transformers, etc.

IV is divided by winding form:
(1) Two-winding transformer: used to connect two voltage levels in the power system.
(2) Three-winding transformer: Generally used in power system regional substation, connecting three voltage levels.
(3) Autotransformer: A power system used to connect different voltages. It can also be used as a normal boost or post-down transformer.
V is divided according to the core form:
(1) Core transformer: Power transformer for high voltage.
(2) Amorphous alloy transformer: Amorphous alloy core transformer is a new type of magnetic conductive material, the no-load current is reduced by about 80%. It is a distribution transformer with ideal energy saving effect, especially suitable for rural power grids and developing regions. Where the load rate is low.
(3) Shell-type transformer: special transformer for high current, such as electric furnace transformer, electric welding transformer; or power transformer for electronic equipment and television, radio, etc.
