Your factory uses more than 1600kva, so it is recommended to use two transformers, which will be more economical than one transformer. If you consider it according to the power factor, your electricity will probably be more than 2800. Therefore, two 1600kva transformers are used, so that the transformer can operate at a load factor of 80% and the transformer can have a longer life.

To determine how big a transformer is needed, you need to know the voltage and current plexus of the electrical equipment. Assuming that the voltage of the electrical equipment is 220V, the power of 2000kW corresponds to the current of the stove is i=p v=2000000 220=. According to the formula of a transformer, the capacity of a transformer is directly proportional to the ratio of input and output currents, and the capacity is inversely proportional to the ratio of input voltage to output voltage.

Suppose the input voltage of the transformer is 220V and the output voltage is 10kV, then the capacity of the transformer is:

Capacity = Input Current Output Current * Input Voltage Output Voltage = 10kV 220V) =

Therefore, a transformer with a capacity of 200kVA is required. In the same way, for a 200kw electrical equipment, assuming that the voltage is 220V and the current is i=p v=200000 220=, according to the same formula, a transformer with a permeability capacity of 20kVA is required.

Three 330kw compressor units share a 1600kva transformer, if approved by the power supply bureau. 6 units need 2 sets of 1600kva transformers. Two sets of 1600kva each have a section of low-voltage bus, and a liaison is set between the two sections of low-voltage busbar for high-voltage metering.

1. Based on the user's average power Shisen factor, the apparent capacity required for 2000kw active equipment is: s=p cos =2000.

2. So you can choose a transformer with a total capacity of 2500 3150kva, and you can also choose a combination of: 1250kva+1250kva, 1000kva+1600kva, 800kva+1600kva, 630kva+2000kva, 500kva+2000kva and other five options.

Summary. Dear, hello, I am glad to answer for you how big a transformer is needed when the power of the equipment is about 3000kw? How is it calculated?

A: 4500kva. Select the voltage rating of the transformer. The voltage of the high-voltage side is equal to the voltage of the connected grid, and the voltage of the low-voltage side is 10% or 5% higher than the voltage of the low-voltage side of the grid (depending on the voltage level of the transformer and the size of the impedance voltage), and the rated capacity is selected.

Calculate the size of the load carried by the transformer (the maximum comprehensive load is required to be counted, and the active load kw value is converted to the apparent power kva), if it is two transformers, then the capacity of each transformer can be selected according to 70% of the maximum comprehensive load, and a transformer should be considered according to the total load, and leave an appropriate margin.

The power of the equipment is about 3000kw, how big is the transformer? How is it calculated? Hello dear, <>

Therefore, with a power factor of 3000 kilowatts, you should choose a transformer with 3333kva. 3000*: Power Factor: Margin system return to the shed, I hope it can help you. <>

Summary. The power of the equipment is about 3000kw, how big is the transformer? How to calculate: 3000*: Power factor: margin factor.

The power of the equipment is about 3000kw, how big is the transformer? How is it calculated?

The power of the equipment is about 3000kw, how big is the training and dismantling transformer that needs to be matched? How to calculate: 3000*: Power factor: margin factor.

The 3000 kW transformer is 6315 amps. The calculation is as follows: 3000000 380 * If you are for power distribution, only a good rental beam with a busbar, there is no such a large cable, to 10 * 120mm five spells, transformer:

For 4500kva high-voltage cable: 95mm cable transformer capacity 100, take integer multiples, and then * high-voltage side current value, if you want to type *144, it is the low-voltage side current value! For a 4500kva transformer, 4500 100 = 45, then the current on the high voltage side is 45*, and the current on the low voltage side is 45 * 144 = 6480A.

250kW electrical equipment requires a transformer with a capacity of 368kW or more.

1. The transformer power factor is generally available), then, the total power of the transformer = 250.

2. According to the "Electric Power Engineering Design Manual", the transformer capacity, for a single transformer with stable load power supply, the load rate is generally about 85%, therefore, in the above example, the transformer capacity = , choose the transformer with a capacity of more than 368kva.

3. If it is a single motor, due to the large starting current, even if measures are taken, the transformer capacity should be increased accordingly.

4. If the three-phase is unbalanced, the transformer capacity should be increased accordingly. Pin Hail.

This requires the calculation of the current to match, assuming a power factor of .

250kw rated current: 250

Matching transformer: load factor) =

The transformers that are close to the calculation results are 400kVA and 500kVA, and 500kVA is recommended.

10kV transformer amount slag fixed carrying capacity: 400

10kV transformer rated current carrying capacity: 500

It is important to understand that the "power factor" is for the load (electrical equipment), not for the transformer that provides the power.

The load has an inductive load that is divided into a high and a resistive load, and the power factor of the resistive load is "1", and the power factor of the inductive load is between ".

The total power of the equipment is 600kw, and the transformer with a capacity of 800kVA is selected.

The capacity specified on the nameplate of the transformer is the rated capacity, which means that the tap changer is located in the main tap, which is the product of the rated no-load voltage, the rated current and the corresponding phase coefficient gear sail.

For three-phase transformers, the rated capacity is equal to = 3 rated phase voltage and phase current, and the rated capacity is generally expressed in KVA or MVA.

The 380V 450kw motor cannot be started directly, its starting current and impact are too large, the power grid can not stand it, and it will always trip as soon as it starts.
