Winding Connection Method Of Three-phase Transformer

Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. It can be divided into: power transformer and special transformer (electric furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, mining transformer, audio transformer, medium frequency transformer, high frequency transformer, impulse transformer, instrument transformer, electronic transformer, reactor, mutual inductor, etc.). Three phase transformers are widely used in circuits with AC 50Hz to 60Hz and voltage below 660V. They are widely used in imported important equipment, precision machine tools, mechanical and electronic equipment, medical equipment, rectifier devices, lighting, etc. Various input and output voltages, connection groups, number and position of regulating taps (generally ± 5%), distribution of winding capacity, allocation of secondary single-phase winding, application of rectifier circuit, whether shell is required, etc. of the product can be carefully designed and manufactured according to the requirements of users.
