Introduction And Principle Of Transformer

A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil, and the iron core (magnetic core). The main functions are voltage transformation, current transformation, impedance transformation, isolation, voltage regulation (magnetic saturation transformer), etc.

Transformers can be divided into distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers Transformer, box-type transformer test transformer, corner transformer, high-current transformer, excitation transformer, etc.

The principle of transformer

A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil, and the iron core (magnetic core). In electrical equipment and wireless circuits, it is often used for voltage rise and fall, impedance matching, safety isolation, etc. In a generator, an electrical potential can be induced in the coil, whether the coil moves through a magnetic field or the magnetic field moves through a stationary coil. In both cases, the value of the magnetic flux is unchanged, but the amount of magnetic flux that intersects with the coil changes, which is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current and impedance.
