Transformer 01

Phase 1, according to the number of points: 

1) single-phase transformer: used for single-phase load and three-phase transformer group. 

2) three-phase transformer: used for three-phase system the rise and fall of voltage. 

2, according to the cooling way points:

 1) dry type transformer: rely on the natural air convection cooling or increase the cooling fan, used in high-rise buildings, more high-speed toll site and local lighting electricity, electronic circuit and other small capacity transformer.

 2) the oil-immersed transformer: rely on oil as cooling medium, such as oil-immersed natural cooling and oil-immersed forced-air cooling, oil immersion cooling, forced oil circulation, etc.

  3, according to utility cent:

 1) power transformer: used for the rise and fall of voltage transmission and distribution system.

 2) instrument transformer, such as voltage transformer, current transformer, used for measuring instrument and relay protection device. 

3) test transformer: can produce high voltage, electrical equipment for high voltage test. 4) special transformer, such as electric furnace transformer, rectifier transformer, adjust transformer, capacitor, phase shifting transformer, etc.

 4, according to the winding form points:

 1) double winding transformer: used to connect two voltage grade of power system. 

2) three winding transformer: generally used in the regional power system transformer substation, connecting the three voltage levels. 

3) the self coupling transformer: used to connect to different voltage of power system. Also can be used as ordinary booster or fall after the transformer. 

5, according to the form of core points:

 1) core transformer: used for high voltage power transformer. 

2) amorphous alloy transformer, amorphous alloy iron core transformer is to use new magnetic materials, no-load current fell about 80%, energy saving effect is ideal distribution transformer, especially suitable for rural power grids and developing regions such as load rate is low.

 3) shell type transformer: used for large current special transformer, such as the electric furnace transformer, electric welding transformer; Or used in electronic instruments, TV, radio power transformer, etc.
