Phase differentiation

It can be divided into three-phase transformers and single-phase transformers. In three-phase power systems, three-phase transformers are generally used. When the capacity is too large and limited by transportation conditions, three single-phase transformers can also be used to form a transformer group in three-phase power systems.

Winding differentiation

It can be divided into dual-winding transformers and triple-winding transformers. Usually, transformers are double-winding transformers, which have two windings on the iron core; one is the original winding, and the other is the secondary winding. Three-winding transformers usually have a large capacity (generally above 5600kva) and are mainly used to connect three transmission lines with different voltage levels. In some special applications, Satons transformers with more windings may also be used.

Structural classification

It can be divided into core-type transformers and shell-type transformers. A transformer whose winding is wrapped around an iron core is called an iron core transformer, while a transformer whose iron core surrounds the outside of the winding is called an iron shell transformer. The two are only slightly different in structure and have no essential difference in principle. Power transformers are all iron core type.

The transformer mainly consists of an iron core, winding, oil tank, conservator, insulating sleeve, Tap Changer, and Gas Relay.
