Winding division

It can be divided into two winding transformers and three winding transformers. Transformers are usually double winding transformers, meaning there are two windings on the iron core. One of them is the primary winding, and the other is the secondary winding.A three-winding transformer is a high-capacity (5600 kVA+) transformer used to connect three transmission lines with different voltages. In special cases, there are more windings for Satons transformers.

Structural classification

It can be divided into the core transformer and the shell transformer. If the winding is wrapped around the iron core, it is an iron core transformer; If the iron core is wrapped around the winding, it is a shell-type transformer. However, they are slightly different in structure and have no essential difference in principle. All power transformers are iron core type.

The transformer is mainly composed of the iron core, winding, oil tank, conservator, insulating sleeve, Tap Changer, Gas Relay, etc.
