1. The role of transformer in power system
2 Common types of transformers
3. Basic structure of power transformer
4. Main components and functions of power transformer
The role of a transformer;
Transformer is a static electrical equipment, it uses the principle of electromagnetic induction to convert one voltage level of AC power into another voltage level of AC power.
Transformer schematic diagram
1. The main role of transformer in power system is to change voltage to promote power transmission.
2. Increasing the voltage can reduce the line loss, improve the transmission economy, to achieve the purpose of long-distance transmission.
3. Reduce the voltage, and convert the high voltage to meet the requirements of users at all levels of voltage.

Two commonly used transformer classification
1 According to phase, it can be divided into:
Single-phase transformer: Used for single-phase load and three-phase transformer sets.
Three-phase transformer: Used for the lifting of three-phase systems.
2: According to the cooling method can be divided into:
Dry transformer: rely on air convection for cooling.
Transformer structure
Oil-immersed transformer: rely on oil as cooling medium, such as oil-immersed self-cooling, oil-immersed air cooling, oil-immersed water cooling, forced oil circulation air cooling, etc.
Three, according to the use can be divided into
Power transformer: Used to raise and lower the voltage of transmission and distribution systems.
Instrument transformers: such as voltage transformers, current transformers, measuring instruments and relay protection devices.
Test transformer: can produce the required voltage, test electrical equipment.
Electric furnace transformer, rectifier transformer, regulating transformer and other special transformers.
Four: according to the form of winding:
Double winding transformer: Used to connect two voltage levels in a power system.
Three winding transformer: generally used to connect three voltage levels of power system regional substations.
Autovariable voltage: Used to connect power systems with different voltages.
It can also be used as a general booster or step-down transformer.
