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). The main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.
Transformers can be divided into distribution transformers, power transformers, fully sealed transformers, combination transformers, dry-type transformers, oil immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, box type transformer test transformers, corner transformers, high current transformers, excitation transformers, etc.
