Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are primary coil, secondary coil and iron core (magnetic core). In electrical equipment and wireless circuits, it is often used for raising and lowering voltage, matching impedance, safety isolation, etc. In the generator, whether the coil moves through the magnetic field or the magnetic field moves through the fixed coil, the electric potential can be induced in the coil. In both cases, the value of magnetic flux remains unchanged, but the number of magnetic flux in the chain crossing the coil changes, which is the principle of mutual inductance. Transformer is a device that uses electromagnetic mutual inductance to transform voltage, current and impedance.
Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core (magnetic core). Main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.
Transformer can be divided into distribution transformer, power transformer, fully sealed transformer, combined transformer, dry-type transformer, oil-immersed transformer, single-phase transformer, furnace transformer, rectifier transformer, reactor, anti-interference transformer, lightning protection transformer, box-type transformer test transformer, corner transformer, high-current transformer, excitation transformer, etc.
