    The air conditioner power is 4500w, and the 4A power cord 32A is open, why is it always tripped

    The air conditioner power is 4500w, and the 4A power cord 32A is open, why is it always tripped The air conditioner power is 4500W, 4 square power cord, and the 32A air switch will trip for a period of time, because it can run for a period of time, so it is not a problem of excessive starting current, so let's analyze the power is 4500W Air conditioning, current and wires and switches during normal operation. First of all, the coldest bacteria in the family analyze the situation of the air conditioner with a power of 4500W in the single-phase circuit, that is, the circuit of 220V voltage: Since we know that the power of the air conditioner is 4500W, since the air conditioner is an inductive load, then we take 0.85 as the power factor cosφ, and also know that the operating voltage is 220V, we can first calculate the operating current; according to the power calculation formula P = UIcosφ, we come Find the calculated current I, I=P/(Ucosφ)= 4500W/(220V×0.85) ≈24A; then we check the safe current-carrying capacity table of the wire, we can know that we should choose the 6 square copper core national standard when the current is 24A Wire, because the safe current carrying capacity of 6 square copper core national standard wire is probably between 32A and 47A, so it is most reasonable to choose 6 square copper core national standard wire, and the choice of switch is 32A; it can be seen that the subject In principle, the 4 square-square national standard copper wire is too small, and the air conditioner will be overloaded for a period of time, causing the wire to be hot, and eventually the air switch will be tripped. If it is not tripped, it is more dangerous. If the time is longer, the wire may catch fire and an electrical fire may occur. Then the editor will give you an analysis of the air conditioner with a power of 4500W in the three-phase circuit, that is, the 380V voltage circuit: As with the above data, since we know that the power of the air conditioner is 4500W, and because the air conditioner is an inductive load, then we take 0.85 as the power factor cosφ, and also know that the operating voltage is 380V, we can first calculate the operating current; according to the power calculation formula P=√3UIcosφ, let’s find the calculated current I, I=P/(√3Ucosφ)=4500W/(1.732×380V×0.85)≈8A; then we check the safe current-carrying capacity table of the wire, we can know that the current is 8A When we should choose 2.5 square copper core national standard wire, because the safety current capacity of 2.5 square copper core national standard wire is approximately 15A to 28A, so choose 2.5 square copper core national standard wire, and the switch chooses 25A That’s all. So, if the voltage is 380V, the wires and switches we configure are too large, and will not cause a trip. The problem is probably due to the air conditioner itself. Find the after-sales service for repair. About the air conditioning power is 4500W, 4 square power cord, 32A air switch, the total trip for a period of time, the editor has analyzed it for everyone, I hope to help everyone! The above are personal opinions for your discussion and use.
