The 16 square meter, three phase, four wire, three fire and one zero unit can carry 6 22Ov3 HP air conditioners.
The 16mm copper wire can support a three-phase four-wire load of approximately 25 kilowatts. The feeding radius should not exceed 50 meters. The power of 3 air conditioners is 2400 watts, so the 16-. square meter three-phase four-wire three lights and one zero Can carry 6 22Ov3 air conditioners.
Extension: Three alternating currents of equal size, same frequency and initial phase difference of 120° are combined to form a three-phase alternating current. Actual three-phase alternating current is generated by a three-phase generator. In the generator there are three identical windings distributed evenly with a spatial difference of 120°. The rotation of the generator can produce three single-phase alternating currents which meet the above conditions. Since the initial phase difference is 120°, there is a ditime difference in the current flowing in each wire. six wires to provide power, but only inside the generator. Connect the three windings in a certain way and use three or four wires to supply power. The alternating current emitted by each winding of the generator is called one phase of the three-phase alternating current, which is the single-phase alternating current we use.
