Transformer body structure
This paper mainly introduces the structure of transformer body from three aspects: core, winding and lead.
I.Transformer core structure
01 The role of silicon steel(Iron) core
Transformers are based on the principle of electromagnetic induction, the magnetic circuit is the medium of electrical energy conversion. Iron core is the main magnetic circuit of the transformer, the main role is magnetic. It converts the electrical energy of the primary circuit into magnetic energy, and from magnetic energy into electrical energy of the secondary circuit.
At the same time, the iron core is the mechanical skeleton of the transformer, and the clamping device of the iron core not only makes the magnetic conductor into a mechanical complete structure, but also has an insulated coil on it, supporting the lead, and almost all the components inside the transformer. The weight of the iron core is the largest in the transformer components, accounting for about 60% of the total weight in the dry transformer, and about 40% in the oil-immersed transformer.
