Information

The invention of the transformer is a great leap forward in the history of the development of human electrical appliances. It can be used to convert voltage, current, and resistance. It can also be used to isolate current and stabilize voltage. It brings great convenience to humans and solves people’s daily life. Tripping or regional power outages caused by excessive voltage, or even serious fire caused by excessive resistance, the invention of the transformer has solved these hidden dangers. So how many types of transformers are there?

Types of transformers:

1. Divided according to the number of phases: single-phase transformer, three-phase transformer and multi-phase transformer.

2. According to the number of windings, it is divided into: double winding, three winding and autotransformer.

3. According to the voltage regulation (voltage tap switching) method, it is divided into: load (excitation, load) voltage regulation transformer and no load (no excitation, no load) voltage regulation transformer.

4. According to its purpose, it is divided into: power transformers, test transformers, measuring transformers (voltage and current transformers), voltage regulators, special transformers (electric furnace transformers, rectifier transformers, welding transformers, control transformers, impact transformers).

5. According to its function, it is divided into: step-up transformer, step-down (distribution) transformer and contact transformer.

6. According to the insulating medium, it is divided into: oil-immersed transformer, dry-type transformer, gas-insulated transformer, etc.

7. According to the cooling method, it is divided into: oil-immersed transformer (oil-immersed natural cooling, oil-immersed air-cooling, oil-immersed water-cooling, forced oil-circulating air-cooling, forced oil-circulating water-cooling), dry-type transformer and gas-filled transformer.

8. According to the iron core structure, it is divided into: core transformer and shell transformer.

9. According to the neutral point insulation level, it is divided into: fully insulated transformer and semi-insulated transformer.
