Dry-type transformers achieve voltage transformation between the input side (high-voltage side) and the output side (low-voltage side) through mutual inductance, without the need for a liquid insulating medium. Their main working principle includes:
The high-voltage side coil generates a magnetic field, which induces an electromotive force in the low-voltage side coil.
Through electromagnetic induction, the input signal voltage is converted into the desired output voltage.
Dry-type transformers use air or other dry materials for insulation, thus avoiding the safety hazards such as oil leakage and explosion that may exist in oil-immersed transformers, improving the reliability and safety of the equipment.
