Transformer is a device that changes the AC voltage by using the principle of electromagnetic induction. The main components are primary coil, secondary coil and metal core (magnetic core). In electronic and electrical equipment, it is often used for voltage gain and loss, impedance matching, safety isolation, etc. Transformer functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage regulation (magnetic saturation transformer), autotransformer, core type and C type, xed type, ed type and CD type.
In order to achieve different voltages, the input winding can use several windings to convert into different input voltages. Multiple windings may be used simultaneously to output different voltages. Three independent windings are powered by three-phase currents of different connection methods (such as star and triangle), and their outputs are the same, that is, three-phase transformers.
1. Various definitions
Single phase transformer: the transformer uses the principle of electromagnetic induction to convert AC voltage. The main components are primary coil, secondary coil and metal core (magnetic core). In electronic and electrical equipment, it is often used for voltage gain and loss, impedance matching, safety isolation, etc.
Three phase transformer: in order to input different voltages, the input winding can also use multiple windings to adapt to different input voltages. Multiple windings may be used simultaneously to output different voltages. Three independent windings are powered by three-phase currents of different connection methods (such as star and triangle), and their outputs are the same, that is, three-phase transformers.
2. Various uses
Single phase transformer: suitable for use and promotion in low-voltage distribution network with low load speed.
Three phase transformer: three phase transformer is widely used in circuits with AC voltage of 50Hz-60Hz and voltage lower than 660V. It is widely used in import important products, precision machine tools, electromechanical products, medical products, rectifiers, lighting, etc.
Input and output voltage, cable group, number and position of control taps (usually ± 5%), winding capacity distribution, installation of secondary winding, application of rectifier circuit and whether it should be shell can be carefully considered. Production and production can be carried out according to customer requirements.
3. Various functions
Single phase transformer: single phase transformer is simple in structure, small in volume, low in loss, mainly due to small metal.
Three phase transformer: a new neutral ground wire is established in the three-phase transformer to reduce the influence of power consumption and metal mismatch.
Although the three-phase protection transformer can prevent various N-G interference (high-frequency pulse and noise), the transformer must be properly grounded, otherwise the interference mode will not be affected.
