What are the advantages of ac three-phase power supply compared with single-phase AC power supply? The output power of three-phase AC power supply of the same size is larger than that of single-phase AC power supply. Three-phase power supply is a widely used power supply equipment at present. In long-distance transmission, three-phase transmission line can save about 25% of the material compared with single-phase transmission line.

Almost all power systems use three-phase AC power supply, but what are the advantages of three-phase AC power supply over single-phase AC power supply?

1. In the case of the same size, the output power of three-phase power supply is larger.

2. The structure and manufacture of three-phase AC power supply are more complex than single-phase power supply, and it is convenient to use and maintain. The vibration during operation is smaller than single-phase power supply.

3. When providing the same high power under the same conditions, especially over long distances, the three-phase transmission line can save about 25% of the material compared with the single-phase transmission line.

4. Three-phase AC power supply is the most widely used power machinery, it has the advantages of simple structure, low price, easy to use, is the main power source of industrial production.

To sum up, three-phase AC power supply is more widely used than single-phase AC power supply. The most commonly used single-phase AC power supply can also be obtained from three-phase AC power supply.
