Three-phase current is by three conducting wires, and each wire is as other two circuits, the phase difference of three of them component
It is followed successively by the one third of a cycle or the electric current at 120 ° of phase angles.
Three-phase alternating current has many good qualities compared with single-phase alternating current, it is converted into mechanical energy in power generation, power transmission and distribution and electric energy
Etc. have apparent superiority.Such as: manufacture threephase generator, transformer single-phase of generating electricity all identical compared with manufacture capacity
Machine, transformer save material, and simple structure, and function admirable, for another example, the three-phase motor as manufactured by same material holds
Amount is bigger than monophase machine by 50%, and in the case where conveying same power, the more single-phase power transmission line of three phase transmission line can save non-ferrous metal
25%, and when electric energy loss is compared with single-phase transmission of electricity, is few.Since three-phase alternating current has above-mentioned advantage so having been widely used.
Existing three-phase current source exports no preferable control to electric current when in use, is unable to ensure electrical stability,
It also cannot achieve remote control function simultaneously.
