Transformer is a kind of electrical equipment used to change the AC voltage, and its working principle is based on electromagnetic induction phenomenon and voltage drop. Through mutual inductance, the transformer can realize the effective conversion and transmission of electric energy.
Transformer is a common and important equipment in power system, which is widely used in power transmission and distribution, electronic equipment and other fields. Its working principle is based on the phenomenon of electromagnetic induction. In the transformer, it includes a main coil and a secondary coil, which are directly connected by a magnetic field instead of an electric circuit. When an alternating current is passed through the main coil, an alternating magnetic field is generated in the iron core, thereby inducing an alternating voltage in the secondary coil.
According to the structure of the transformer, the ratio of the number of turns of the main and auxiliary coils determines the transformation ratio of the transformer, and then determines the voltage at the output end of the transformer. When the ratio of the number of turns of the main and auxiliary coils is greater than 1, it is a step-up transformer, and the voltage at the output end is higher than that at the input end; otherwise, it is a step-down transformer.
In the working process of the transformer, the transmission and conversion of electric energy are realized through the function of the transformer, which can not only increase the voltage to reduce the transmission loss, but also reduce the voltage to meet the working requirements of different equipment. In addition, the transformer also has the functions of isolating power supply and providing circuit matching to ensure the normal operation of the power system.
In general, the transformer is an important electrical equipment, its working principle is based on the phenomenon of electromagnetic induction, through the regulation of the transformer, to meet the voltage requirements of various electrical equipment, play a vital role.
