Background

A transformer is a device that changes an alternating voltage using the principle of electromagnetic induction, and main components are a primary coil, a secondary coil, and an iron core (magnetic core). In electrical equipment and wireless circuits, the high-voltage power supply is often used for voltage rise and fall, impedance matching, safety isolation and the like. In a generator, an electrical potential can be induced in a coil, whether the coil is moved through a magnetic field or a magnetic field is moved through a stationary coil. In both cases, the value of the magnetic flux is constant, but the amount of the magnetic flux linked with the coil varies, which is the principle of mutual induction. A transformer is a device for transforming voltage, current and impedance by using mutual electromagnetic induction.

Oil-immersed transformers use oil as the primary insulation means of the transformer and rely on oil as the cooling medium, such as oil-immersed self-cooling, oil-immersed air-cooling, oil-immersed water-cooling, forced oil circulation, etc.
