What is the difference between a control transformer and an ordinary transformer?
The difference between a control transformer and an ordinary transformer: an ordinary transformer mainly changes the voltage, and the control transformer transmits a signal.
1. Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance transformation, isolation, voltage regulation (magnetic saturation transformer) and so on.
2, according to the use can be divided into: power transformers and special transformers (electric furnace change, rectifier transformer, power frequency test transformer, voltage regulator, mining transformer, audio transformer, intermediate frequency transformer, high frequency transformer, impact transformer, instrument transformer, Electronic transformers, reactors, transformers, etc.). The circuit symbol is commonly used as the beginning of the number. For example: T01, T201, etc.
