Encounter an electrical transformer
Power Transformers are one of the main equipment in power plants and substations. The function of a transformer is multi-faceted. It can not only increase voltage to deliver electrical energy to the power-consuming areas but also reduce voltage to various levels of usage voltage to meet the demands of electricity consumption.01 Transformers are classified by phase number:
Single-phase transformer: used for single-phase loads and three-phase transformer groups; Three-phase transformer: It is used for raising and lowering voltage in three-phase systems
02 Classified by use:
Power transformer: Used for raising and lowering voltage in power transmission and distribution systems;
Instrument transformers: such as voltage transformers and current transformers, are used in measuring instruments and relay protection devices
Test transformer: It can generate high voltage and conduct high-voltage tests on electrical equipment.
Special transformer.
03 Classified by cooling method
Dry-type transformer
Oil-immersed transformer
04 Classified by the number of windings
Single-winding transformer
Double-winding transformer
Three-winding transformer
Multi-winding transformer
Different types of transformers are used in different situations. Here, we will talk about the most common oil-immersed transformers and dry-type transformers. Today, let's first introduce the oil-immersed transformer.
Oil-immersed transformer
The main difference between oil-immersed transformers and other types of transformers lies in the different insulating agents. By immerging both the core and coils of the transformer in specific oil, the insulation performance of the transformer can be significantly enhanced. Oil-immersed transformers are mainly used in power systems, power grids, and industrial manufacturing fields. In addition to its good insulation, it is also durable and can operate for a long time. Due to its fast heat dissipation, it effectively isolates short-circuit faults.
