Can industrial intelligent power-saving regulator really save electricity?

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

The jump of the relay stabilized the voltage. When the grid voltage fluctuates, the automatic correction circuit of the power regulator is started to make the internal relay act. Forcing the output voltage to stay near the set value, this circuit has the advantages of simple circuit, but the disadvantage is that the voltage stabilization accuracy is not high, and the power will be cut off instantly every time the relay jumps and shifts, resulting in spark interference.

Relevant requirements of intelligent power-saving voltage regulator:

1, the voltage regulator shall not be overloaded. When the mains voltage is low, the output capacity decreases, so the load of the voltage regulator should be reduced accordingly.

2. The wires connected with the voltage regulator should have enough load surface to prevent heating and reduce pressure drop. Voltage regulators with 2KVA and above capacity are connected by terminals, and a single copper conductor should be selected, and the terminal screws should be tightened to prevent the connection from heating.

3. When choosing refrigerators, air conditioners, water pumps and other electrical appliances. When the motor is running, you should choose a voltage regulator with a capacity of more than 3 times, so as to avoid that the starting current of the equipment exceeds the fuse current of the voltage regulator or the current of the overcurrent protection circuit breaker, which may cause the fuse of the voltage regulator to blow or the circuit breaker to trip or the voltage drop is too large to work.
