How much can the maximum current of the transformer be used in 630KVA?

How much can the maximum current of transformer 630kva be used Solution:

The maximum current of a 630kVA transformer depends on the rated voltage on the low voltage side.

The value is determined.

If the rated voltage on the low voltage side of the 630kVA transformer is 400V, according to the capacity S voltage * current, it can be calculated:

Current rating. i 6300 (kiloamperes 9100 amps, the maximum long-term current that each phase can withstand is 9100A.

Overload operation is allowed in a short period of time, and the allowable amount is inversely proportional to time and load rate, and the maximum overload is 20% within 2 hours.

That is, the maximum allowable current of 9100*(1+20%) 10900A within 2 hours.

How much power can be used in a 630kva transformer:

Without additional measures, the 630kVA transformer can use up to 420kW power appliances.

Transformer power factor.

Generally, there are also there), then, the total power of the transformer = 630*.

According to the Power Engineering Design Manual

Transformer capacity, for a single transformer with stable load power supply, the load rate is generally about 85%, therefore, in the above example, the electrical power = 504 * 85% =.

If it is a single large.

Power motors, due to the large starting current, even if measures are taken, the power consumption should be reduced accordingly.

If the three phases are unbalanced.

It is also necessary to reduce the power consumption accordingly.

630kva=504kw, according to the formula for calculating the three-phase active power (low-voltage side current i=active power 504kw 3 voltage 400v power factor, according to the transformer energy conservation law, voltage ratio (10kv times), so high-voltage side current = low-voltage side current.

This question is up to me, it takes a little time to type, so please be patient.

Summary. 1. Rated current of 630kva transformer.

1. The voltage and current values on all transformer name plates are wireless. Because the user of the transformer is concerned about the use, the transformer manufacturer gives the value of line voltage and line current. But in transformer design and manufacturing, he calculates the voltage and current of each phase.

So, he is concerned with the phase voltage and the phase current.

2. The relationship between the line and the phase depends on the connection of the coil. Now the general distribution transformer is DYN11 connection. The high voltage is a D connection (triangle connection).

Feature: The line voltage is equal to the phase voltage. The line current is equal to the phase current which is 3 times the root number. The low voltage is Y-connection (star connection), which is characterized by the line voltage being equal to 3 times the root number of the phase voltage, and the line current being equal to the phase current.

3. For example: 630kva transformer, the low voltage is 400V (line) The output line current is: I2 line = 630 The low voltage is Y, and the phase current is equal to the line current.

Therefore, this method is also used for phase current, and the current of high-voltage lines and phases can also be calculated.

1) Secondary side rated current: i 630000 400.

2) Primary side rated current: i 630000 10000.

Hello dear and happy to answer for you. How many kilowatts can a 630kva transformer carry? If the transformer is all electrically heated (resistive) loads, theoretically it can carry a load of 630 kilowatts.

However, according to the regulations of the Electricity Bureau, the maximum load is 85% of the full load, which is 535kva. If all are inductive loads such as motors, it is generally 6 discounts, that is, 378 kilowatts of motor loads, if both loads are available, then 7 discounts (441kw) or 8 folds (504kw), it depends on which load accounts for more proportions. In fact, according to the regulations of the Electricity Bureau, the maximum load cannot exceed 535kva.

Summary. How many kW can a 630kva transformer carry

0kva transformer with 400kw load, no problem at all.

KVA is the apparent power (or nominal power) of the transformer. is the sum of the active power and the reactive power (is the geometric sum, that is, the vector sum, not the algebraic sum).

kW is the total active power consumption of your load.

3. If the power factor of your load is 80% (generally the minimum requirement, after compensation, it will be greater than 80%). Then, the apparent power of the transformer he needs is: p=400 <630kva.

If you choose a 500kVA transformer, it can also meet the requirements. And the choice of 630kva is to leave room for improvement. Hope it helps!
