Industrial Voltage Stabilizer Inner Detail
In fact, the three-phase voltage stabilizer connects the three voltage stabilizing units with "Y" connection method, and then uses the control circuit board and the motor drive system to control the voltage regulating transformer, so as to achieve the function of stabilizing the output voltage.
If the sliding arms of the three voltage regulating transformers are driven by one motor, the voltage regulating mode is the unified voltage stabilizer. If the sliding arms of the three voltage regulating transformers are independently adjusted by three motors, the three-phase split regulation voltage stabilizer is the same as the single-phase voltage stabilizer.
In the process of voltage regulation, the regulator is realized by moving the carbon brush to change the number of contact coil turns. Then, during the adjustment, it is required to keep contact with the coil at all times, otherwise, the power will be cut off.
