1 Efficacy of transformers in power systems.
2 Common types of transformers.
3 The main structure of the power transformer.
4 The key components and functions of power transformers.
The efficiency of the transformer;
A transformer is a static data electrical device that uses the magnetic effect of current to convert AC power at one voltage level into AC power at another voltage level.
Transformer circuit schematic.
1. The primary function of a transformer in a power system is to change the voltage to facilitate the transfer of output power.
2. Increasing the voltage can reduce the loss of distribution lines, improve the rationality of closing, and achieve the purpose of long-distance closing.
3. Reduce the voltage and convert the high voltage into various application voltages required by customers to meet customer requirements.

Two common transformer classification.
1 According to the number of phases, it can be divided into:
Single-phase electrical transformers: for single-phase loads and three-phase transformer banks.
Single-phase electrical protection transformer.
Three-phase transformer: Used for regulating voltage of three-phase system software.
Oil to Transformer.

2: According to the cooling method, it can be divided into:
Dry Test Transformer: Refrigeration by means of air convection.
Transformer Construction
Oil-transformed transformer: With oil as a refrigeration substance, such as oil-immersed over-temperature protection, oil-to-air-cooled, oil-immersed cooling, forced oil circulation system air-cooled, etc.
3: According to the use can be divided into.
Power transformer: used for adjustment of power transmission and transformation system software.
Instrument equipment transformers: such as voltage and voltage transformers, current transformers, used for testing instruments and generator-transformer groups.
Experimental Transformer: Can generate the required voltage to carry out experiments on power distribution equipment.
Special transformers: such as heating furnace transformers, rectifier transformers, adjusting transformers, etc.
4: Division by winding mode:
Double winding transformer: used to connect 2 voltage levels in the power system.
Three-winding transformer: generally used in power distribution substations in the power system, connecting three voltage levels.
Autotransformer: used to connect power systems with different voltages. It can also be used as a general transformer or step-down transformer.
