lOperating principle of the autotransformer

The working principle of the autocoupling transformer is based on the law of electromagnetic induction. It is characterized by primary and secondary codings sharing the same set of coils, with different taps to achieve a boost or step-down. When the input winding causes an AC current, the changing current causes a magnetic field change, which generates an induced voltage in the coil. Due to the tight coupling of the primary and secondary windings, the autotransformer can achieve an efficient voltage transformation.

lApplication scope of the autotransformer

(1)Application in the power system: In the power system, the self-coupling transformer is mainly used for the connection between the power grids, especially in the voltage level of 220KV and above, which plays a key role. Because of their small size, low cost and high energy transfer efficiency, autotransformers are widely used in power systems.

(2)Motor voltage start: when the motor starts, in order to reduce the impact on the power grid, the autotransformer can be used for voltage start. In this way, the starting current of the motor is reduced, thus protecting the power grid and the motor itself.

(3)Laboratory and research sites: Because the autotransformer can flexibly adjust the output voltage, it is often used as an adjustable power supply in laboratories and research institutions to provide stable power support for various experiments and studies.

In Summary

In conclusion, autotransformer plays an important role in electric power system and scientific research experiment with its unique working principle and wide application range.
