The main features are: voltage conversion, electric flow conversion, characteristic impedance conversion, one separated and adjusted (contrast of magnetic transformer), etc.
By destination, it can be divided into: unique power engineering transformer and transformer (electrical variable, rectifier variability, frequency experimental transformer, regulated power supply, more and more mining, audio transformer, high frequency transformer, high frequency transformer, impulse transformer, instrument transformer, electronic device transformer, series reactor, transformer, etc.).
The magnetic effect heating cooker using current is the basic principle of cooking equipment by electrical equipment. According to the high-frequency electromagnetic induction heating coil (i.e., excitation regulator coil), in the high-frequency power engineering conversion equipment, the control board cooking pot and magnet raw materials and other components.
The inner side coil is a transformer primary and secondary coil translation transformation. At the beginning, the internal calorific value of the intermediate coil hard disk includes the communication AC voltage output, which inevitably causes the induced electromotive force. According to the induced electromotive force of the heating resistance of the pot itself (so the pot itself is supported) in the secondary pot, heat is caused. Transformer classification.
The transformer converts the communication AC voltage, AC circuit and equipment. When according to the primary and intermediate AC circuit of the coil, the above core (or core) then causes the characteristic impedance of the communication AC magnetic flux, the secondary coil magnetic induction coil voltage (or current).
The utility model is composed of a transformer core (or core) and a coil. The coil has two or more windings, and its characteristics depend on that the winding connected to the switching power supply is called a junior middle level coil, which is called a part of the coil rewinder.
1. According to application classification: Power Engineering transformer, unique transformer (furnace into rectifier, variability, frequency detection, voltage transformer, voltage controller, more and more mines, audio transformer, high frequency transformer, high frequency transformer, impulse transformer, instrument transformer, electronic device transformer, series reactor, transformer, etc.).
2. According to the structure classification: there are double winding transformer, three winding transformer, multi winding transformer and autotransformer.
3. According to the classification of refrigeration methods: of course refrigeration, air cooling, water cooling, forced oil circulation system, gas (water) refrigeration, and water cooling.
4. According to the type of core or coil structure: core transformer (inserted core, C-type transformer core, ferrite core), shell transformer (inserted core, C-type transformer core, ferrite core), ring transformer, transformer metal foil, radiation source transformer.
5. According to the phase classification of switching power supply: single-phase electric transformer, three-phase transformer and multi-component transformer.
6. Classified by conductive raw materials: copper core transformer, transformer and semi copper aluminum, semi aluminum, nanotube transformer.
7. According to the voltage mode, it can be divided into on load tapping of voltage transformer without excitation regulator.
8. According to a separated neutral classification level: full protection transformer, semi insulation layer (class classification insulation layer) transformer.
