Is the 380V 16 kW, 220V 19 kW, three phase 380V 100A air opening belt moving?

Yes, and more than enough. But be sure to distribute the 220V load evenly to the three-phase power supply.

This problem looks simple, but in fact it is more complicated, when it is all AC motor load, the line current is the power factor, and the efficiency is taken, which is just near the critical value.

First of all, we need to know the following information:

V16KW and 220V19KW are AC motor loads? Resistive load? Whether the load is balanced.

2. If they are all inductive loads such as AC motors, will they be started directly at the same time? Buck start? Soft start, variable frequency start?

A overcurrent trip characteristic curve of air opening, b, c, d?

Based on the above information, the following judgments can be made:

1. If the load is a three-phase resistive load, and the load is balanced, the air can be driven. At this time, the line current is. When it is unbalanced, as long as a certain phase does not exceed 100A, the empty opening can be driven.

2. If the load is a three-phase motor load, when soft start and frequency conversion start are used, the air can be driven.

3. If the load is a three-phase motor load, if the characteristic curve of the empty open overcurrent trip is D type, the air open can be driven.

4. If the load is a three-phase motor load, when the step-down start, if the empty open overcurrent tripping characteristic curve is C and D type, the empty open can be driven.

5. If the load is a three-phase motor load, when direct start and step-down start are used, if the characteristic curve of empty open overcurrent trip is type B, the empty open belt will not move.

6. No matter what type of load, as long as the current of a certain phase exceeds 100A, it cannot be carried out when it is opened.

The above is a preliminary judgment, and the details also need to know the number of equipment, equipment characteristics, equipment capacity, wiring mode, starting sequence, load curve, cycle, etc.

If 220v19 kW can not be divided into three phases. The current is already 86 amps (excluding the power factor). For this current 100 amps switch is no longer enough.

In order to improve reliability, the switch must be derated. A 100 amp switch uses a maximum continuous current of 50 amps.

100A air opening can be loaded at 380V voltage, and 22KW can be loaded at 220V voltage, and the success rate of power calculation formula conversion is:

1. For single-phase electricity p=ui=220*100=22000w=22kw, 100A air opening can carry 22kw load.

2. For three-phase electricity, the power factor is pressed.

p= 3uicos = 3*380*100*, 100a air can be loaded.

According to the apparent power estimation, it can theoretically carry a three-phase load of 100 kilowatts.

However, if the load is an inductive load such as an electric motor, the power factor is cos 1.

The load to be discounted.

Conservative 37kw, it depends on what way you start, if the frequency conversion then 377 has no problem,

The resistive load is 16A, and the inductive load is 20A

According to your description, 380v 100kw, three-phase power supply.

Calculation: 100kw (3*380) 88a

Air opening: 300A or more.

Empty rack wire: BV25mm

Threading wire: BV35mm

Answer: 100 kW 380V three-phase electricity, with the rated working current of more than 400A air open.

Analysis: According to P=UI, i=P U=9000 (380, which is the power factor, 380V three-phase power supply 100 kilowatt motor working current, its access switch should be more than 400A.

Three-phase 12 kilowatt load, estimated current of 24A per phase, according to the nature of the load, 40A plastic shell should be selected for air opening, and it should be ***.

How many kilowatts can a 380V 100A air open carry?

Hello, it is a pleasure to serve you and give you the following answer: How many kilowatts can the air opening of 380V100A carry? According to the electric power formula p=u*i, it can be concluded that the kilowatt number of the 380V100A air open spine energy band is 38000 kilowatts.

Electrical power p, i.e., power, refers to the product of voltage u and current i in watts (w), and slag infiltration 1 watt is equal to 1000 kilowatts, that is, 1 kilowatt (kw) = 1000 watts (w). Therefore, the kW of the 380V100A air-open energy band is 38,000 kW. Air opening is an electrical device, its main function is to protect the circuit from overload, short circuit and leakage and other dangerous dust and damage, as well as to control the opening and closing of the circuit.

The capacity of the air open refers to the maximum current it can withstand, the unit is amperes (a), the larger its capacity, the greater the current it can withstand, and the greater the power it can with.

The air switch of 380V 180A can be with kW. The calculation here is: power (kilowatts) = voltage (volts) current (ampere) three-phase power factor.

Therefore, the power that a 380V 180A air switch can carry is: P = 380V 180A three-phase power factor) = 68,352 watts, i.e. kilowatts.

Multiply the two of them to get the power. Kw.

Apparent power. Voltage (V) Current (A).

160A air switch.

The rated current is 160A (the same three-phase can pass 160A current) and the single-phase voltage is 220 volts.

So theoretically each phase can withstand:

220×160)＝35,200w＝

A: It can withstand a maximum load of about 35 kilowatts.

Dear, hello, I am very happy to serve you, 16000 watts with 380v with how much air to answer 380 volts 16 kilowatt electric furnace with 40 amp air open. The 16KW380V electric furnace is a resistive load, its working current is about 24A, and the air opening with a capacity of 30A is optional. Three-phase electric 16kw electric furnace, rated current value of about 24A.

The motor equipped with air opening is a step-down start, with an air opening of about 60A, because there are many brands of air opening, and the quality is different, generally one kilowatt with 4A air opening. Power = voltage multiplied by current, then current = power divided by voltage is 16000 divided by 220=, or 16000 divided by 380=, now it is understood that single-phase electricity chooses C80A, three-phase electricity chooses 50 or 63A air open.
