automatic voltage regulator

Automatic voltage regulator is a power auxiliary equipment that can convert unstable voltage fluctuations into stable voltage output. Whether it is a single-phase automatic voltage regulator or a three-phase automatic voltage regulator, its working principle and function are the same, but the only difference lies in the internal structure and output voltage.

A.The composition structure of an automatic voltage regulator:

The automatic voltage regulator mainly consists of three components: control circuit, drive circuit, and transformer. The control circuit calculates the voltage and sends control commands to the drive circuit. The drive circuit then changes the number of coil turns in the voltage regulator to stabilize the voltage.

B.What is a single-phase automatic voltage regulator:

A single-phase automatic voltage regulator is mainly composed of a live wire and a neutral wire. The voltage standards vary in different countries, with some countries having a single-phase voltage of 110V or 140V, while in China it is generally 220V,

C.The difference between single-phase automatic voltage regulator and three-phase automatic voltage regulator:

A three-phase automatic voltage regulator is composed of three live wires and one neutral wire. Its output voltage is 380V, and some countries have different voltages such as 420V, 450V, 320V, etc. The three-phase automatic voltage regulator is mainly used for industrial and large-scale equipment.

D.Application of single-phase automatic voltage regulator and three-phase automatic voltage regulator:

When choosing an automatic voltage regulator, we can distinguish it based on the identification of the electrical equipment or use it based on the location. But for industrial sites, there are usually professional electricians who provide us with power installation and selection, while for household use, equipment is mainly single-phase. If it is for our household use, we can use a single-phase automatic voltage regulator.
