Components Of Oil Immersed Transformer

Iron core: The iron core is one of the basic components of the transformer and the magnetic circuit part of the transformer. The primary and secondary windings of the transformer are on the iron core. In order to improve the magnetic conductivity of the magnetic circuit and reduce the eddy current loss in the iron core, the iron core is usually made of 0.35mm silicon steel sheet with insulated surface. The iron core is divided into two parts: iron core column and iron yoke. The iron core column is sleeved with windings, and the iron yoke connects the iron core, which is used to close the magnetic circuit.

Winding (coil): The winding is also one of the basic components of a transformer. It is the circuit part of the transformer, generally wrapped with copper or aluminum wires wrapped in insulating paper. The winding connected to the high-voltage network is high-voltage winding, and the winding connected to the low-voltage network is low-voltage winding. The winding acts as the carrier of current, generating magnetic flux and induced electromotive force.

Accessories: accessories of power transformer include oil tank, conservator, tap changer, safety air passage, insulating sleeve, etc. Its function is to ensure the safe and reliable operation of the transformer.

The main structure of oil immersed transformer consists of body, oil tank, cooling equipment, protection equipment and outgoing line equipment. The body includes iron core, winding (winding), insulation, lead wire and tap changer; The oil tank includes the oil tank body and oil tank accessories; The cooling equipment includes radiator and cooler; Protection equipment includes oil conservator, oil pointer, safety air passage, moisture absorber, temperature measuring element and gas relay; The outgoing line equipment includes high and low voltage bushings.
