3 Phase Dry Type Transformer Introduction
3 Phase Dry Type Transformer Definition
Three-phase dry-type transformers are the main components of various power supplies and electrical equipment. It 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 raising and lowering voltage, matching impedance, safety isolation, etc. In a generator, whether the coil moves through the magnetic field or the magnetic field moves through the fixed coil, an electric potential can be induced in the coil. In both cases, the value of the magnetic flux remains the same, but the amount of magnetic flux intersecting the coil is different. Change, this is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current and impedance.
3 Phase Dry Type Transformer Working Principle
The principle of electromagnetic induction uses electromagnetic mutual induction to transform voltage, current and impedance.
