Dry Transformer: a power transmission tool in the era of clean energy

Dry Transformers realize voltage conversion by transmitting electrical energy from one circuit to another. This process involves the principle of electromagnetic induction and the role of important components such as windings and iron cores.
Let's take a look at the application of electromagnetic induction principles in dry-type transformers. According to Faraday's law of electromagnetic induction, when the magnetic flux in a conductor changes, an induced electromotive force is generated in the conductor. In a dry-type transformer, the alternating current of the input power supply in the high-voltage winding generates an alternating magnetic field. This magnetic field passes through the iron core and is induced into the low-voltage winding, thereby generating an induced electromotive force in the low-voltage winding to realize the transmission of electrical energy. .
Windings play an important role in dry-type transformers. The high-voltage winding and the low-voltage winding are located at both ends of the transformer. They are conductive coils wrapped by insulating materials. When the current in the high-voltage winding generates a magnetic field, since it is connected to the low-voltage winding, this magnetic field will also affect the low-voltage winding, thereby inducing an electromotive force in the low-voltage winding, allowing electrical energy to be transmitted. By designing high-voltage and low-voltage windings with different numbers of turns, the conversion between input voltage and output voltage can be achieved.
The iron core is also a vital component of dry-type transformers. The iron core is usually composed of multiple insulated stacked silicon steel sheets. Its main function is to concentrate the magnetic field, reduce the loss of magnetic flux and improve the efficiency of the transformer. Core selection and design have a significant impact on transformer performance and efficiency.
Dry Transformers realize the transmission of electrical energy and conversion of voltage through the synergy of electromagnetic induction principles, windings, iron cores and other components. This technology has important applications in power systems, providing reliable solutions for power transmission and distribution.
