The main functions of the transformer are working voltage transformation, current quantity transformation, characteristic impedance transformation, protection, voltage regulator tube, etc. According to the main purpose, transformers can be divided into power engineering transformers and special transformers.
The induction cooker is an electric cooker manufactured by the basic principle of heating by the magnetic effect of electric current. It consists of a high-frequency electromagnetic induction heating electromagnetic coil (that is, an excitation coil), a high-frequency output power conversion device, a control board, and a bottom pot of magnet raw materials.
Classified by main purposes: power engineering transformers, special transformers.Classified by structure: double-winding transformer, three-winding transformer, multi-winding transformer, autotransformer.
According to the refrigeration method: of course refrigeration, air-cooled, water-cooled heat dissipation, forced oil circulation system air (water) cooling, water cooling. Inductor.
Classified by transformation method: Divided into non-excitation regulator transformer and on-load transformer(toroidal transformer inverter for home).
Classified according to the flame retardant grade of the neutral wire: transformers with a full insulation layer and semi-insulation layer (class classification insulation layer).
Classified by transformer core or electromagnetic coil structure: transformer core transformer (inserted into transformer core, C transformer core, ferrite core transformer core), shell transformer (inserted into transformer core, C transformer iron Core, ferrite core transformer core), toroidal transformer, metal material foil transformer, radiation source transformer, etc. Classified according to the number of switching power supply phases: single-phase electric transformer, three-phase transformer, multi-component transformer.
The heating electromagnetic coil board in the heating furnace and the induction cooker constitutes a high-frequency transformer. The internal electromagnetic coil is a key part of the transformer, and the primary and secondary part is the heating furnace. When the internal primary heating electromagnetic coil plate has an alternating current output, it will inevitably cause induced electromotive force on the secondary furnace wall, which will generate heat according to the resistor of the furnace wall.
The transformer consists of a transformer core and an electromagnetic coil. The electromagnetic coil has two or more windings. The winding connected to the switching power supply is called the primary electromagnetic coil, and the others are called the secondary electromagnetic coil.
A transformer is a device that converts AC current, AC circuit, and characteristic impedance. When there is an AC circuit in the primary electromagnetic coil, the iron core will cause communication AC magnetic flux, which in turn will cause a working voltage (or current) in the second electromagnetic coil.
