Power Transformer
A power transformer is a static electrical device that is used to change a certain value of alternating voltage (current) into another or several voltages (current) of the same frequency with different values.
According to Standard
1.GB 6451 Specification and technical requirements for oil-immersed power transformers
2.IEC 60076 Power Transformers
3.AS NZS 60076 Power Transformers
4.CSAC88-16 Power Transformers
5.ANSI/IEEE C57.12.00 IEEE Standard for General Requirements for Liquid-Immersed Distribution, Power, and Regulating Transformers
6.GOST R 52719 POWER TRANSFORMERS – GENERAL SPECIFICATIONS
According to purpose
1 Power transformer: used to increase and decrease the voltage of the power 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 conduct high voltage test on electrical equipment.
4 Special transformers: electric furnace transformers, rectifier transformers, adjusting transformers, capacitive transformers, phase-shifting transformers, etc.
According to the number of phases
1 Single-phase transformer: used for single-phase loads and three-phase transformer groups.
2 Three-phase transformer: used to increase and decrease the voltage of a three-phase system.
According to the cooling method
1 Dry-type transformer: Relying on air convection for natural cooling or adding fan cooling, it is mostly used for small-capacity transformers such as high-rise buildings, high-speed toll stations, local lighting, and electronic circuits.
2 Oil-immersed transformer: Relying on oil as the cooling medium, such as oil-immersed natural cooling, oil-immersed air cooling, oil-immersed water cooling, forced oil circulation, etc.
According to the winding form
1 Double winding transformer: used to connect the power system
2 Three-winding transformers: generally used in power system regional substations to connect three voltage levels.
3 Autotransformer: used to connect power systems with different voltages. It can also be used as an ordinary step-up or step-down transformer.
