Technical development of transformers and regulators

Transformer is a device that changes AC voltage by using the principle of electromagnetic induction. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. It can be divided into distribution transformer, power transformer, fully sealed transformer, combined transformer, dry-type transformer, oil immersed transformer, single-phase transformer, furnace transformer, rectifier transformer, etc.

A voltage Regulator is a device that stabilizes the output voltage. The regulator consists of voltage regulating circuit, control circuit and servo motor. When the input voltage or load changes, the control circuit samples, compares and amplifies, and then drives the servo motor to rotate to change the position of the carbon brush of the voltage regulator. By automatically adjusting the coil turns ratio, the output voltage is kept stable.

In short, transformer and voltage regulator are voltage control equipment, which are widely used in the power sector. With the rapid development of modern science and technology, China's power demand continues to increase, which leads to the rapid development of transformer and voltage regulator industry.
