Power transformer: the core equipment of the distribution system
Power transformers are an indispensable part of the power supply and distribution system, and their main task is to change the magnitude of the AC voltage. The following are the classifications and characteristics of power transformers:
Classified by function: step-up transformer and step-down transformer
A step-up transformer is used to raise low voltage to high voltage, while a step-down transformer is the opposite, lowering high voltage to low voltage.
Classified by phase number: single-phase and three-phase transformers
Single phase transformers are suitable for single-phase circuits, while three-phase transformers are used for three-phase circuits to provide a more stable power supply.
Classification by material of winding conductors: copper winding and aluminum winding transformers
Copper winding transformers have high conductivity and thermal stability, while aluminum winding transformers are more cost-effective.
Classified by cooling method: oil immersed and dry-type power transformers
Oil immersed transformers are cooled by oil, while dry-type transformers use air cooling and are suitable for dry environments.
Classified by purpose: ordinary transformers and special transformers
Ordinary transformers are suitable for general power needs, while special transformers are used for special occasions such as high current, high voltage, etc.
