The principle of three-phase AC circuit and the cause of the generator use three-phase communication

The three-phase AC circuit is widely used in industrial and agricultural production. Current electricity production, delivery and distribution, almost all three-phase system. The so-called three-phase AC circuit refers to a circuit system composed of three single-phase AC circuits. In these three single-phase circuits. Each having a sinusoidal AC power force effect. The zui large value and frequency of the three electromotive force is about the same, but the phase is different from each other, such as three electromotive force is referred to as a three-phase impediment. We make each single-phase circuit that make up the three-phase circuit become a phase. The reason why three-phase communication is used because he is the advantage of two aspects of the main giant friends compared to single-phase communication: (1) use three-phase system in the case where the conveying power is the same, the voltage is the same and the distance, the line loss is equal, using three-phase Transmission saves the amount of aluminum with power transmission lines. (1) Three asynchronous motors widely used in industrial and agricultural production are advantages compared with three-phase exchange as power supplies, such motors and single phase, have the advantages of simple structure, low price, good performance and reliable performance. Therefore, based on the single-phase AC circuit, further study three-phase alternating current circuit is important.
