Basic knowledge of electricity: Analysis of four common transformer types and their application scenarios
Transformers are indispensable core equipment in modern power systems, used to regulate voltage, transmit energy, and ensure stable power supply. According to different functions and applications, transformers are mainly divided into the following four types:
Power transformers: used in high-voltage transmission systems to connect power stations and transmission lines.
Distribution transformers: installed in residential or industrial areas, responsible for reducing high voltage to usable low voltage.
Autotransformer: has a structure with some coils shared, small size, high efficiency, suitable for limited space occasions.
Instrument transformers: including current transformers and voltage transformers, used for measurement and protection systems.
Mastering these basic knowledge will help to more reasonably select and apply transformers and improve the efficiency and safety of power systems.
