Transformer‘s introduction and structure

Transformer factory said that there are many types of transformers, according to its use, structure, phase number, cooling methods and other different to be classified.  

1, according to the classification of use: power transformers, special transformers (furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, mine transformer, audio transformer, medium frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer, reactor, transformer, etc.).  

2, according to the structure of the classification: double-winding transformer, three-winding transformer, multi-winding transformer, autotransformer.  

3, according to the cooling method classification: oil immersed transformer, dry type transformer.  

4. Classified by cooling methods: natural cooling, air cooling, water cooling, forced oil circulation air (water) cooling, and water cooling, etc.  

5, according to the core or coil structure classification: core transformer (insert core, C core, ferrite core), shell transformer (insert core, C core, ferrite core), ring transformer, metal foil transformer, radiant transformer, etc.  

6, according to the number of power supply classification: single-phase transformer, three-phase transformer, multi-phase transformer.  

7, transformer factory according to the conductive material classification: copper wire transformer, aluminum wire transformer and half copper half aluminum, superconducting transformers.  

8, according to the classification of voltage regulation: can be divided into no excitation voltage regulating transformer, on-load voltage regulating transformer.  

9, according to the neutral insulation level classification: full insulation transformer, half insulation (classification insulation) transformer.  

Structure of transformer  

The core and winding are the main parts of the transformer, which constitute the body of the transformer.  The structure of three-phase oil-immersed power transformer and three-phase coherent power transformer insulated by epoxy resin is introduced.
