The three-phase voltage stabilizer actually connects three voltage stabilizing units together with a "Y" connection method, and then uses the control circuit board and motor drive system to control the voltage regulating transformer to achieve the function of stabilizing the output voltage.
If the sliding arms of the three voltage regulating transformers are all driven by one motor, the voltage regulation method is a unified voltage regulator. If the sliding arms of the three voltage regulating transformers are independently adjusted by three motors, the voltage regulator is a three-phase regulator. Sub-adjustable voltage regulators work on the same principle as single-phase voltage regulators.
During the voltage regulation process of the voltage regulator, this is achieved by moving the carbon brush to change the number of coil turns in contact. Then, it is required to keep in contact with the coil at all times during adjustment, otherwise power outage will occur.
