The 400kva transformer is a device that uses the principle of electromagnetic induction to transform AC voltage. Its main components include primary coil, secondary coil and iron core.
In the electronics profession, 400kva transformers are often seen, and the most common ones are used as voltage conversion and isolation in the power supply.
At rated power, the ratio between the output power of the 400kva transformer and the input power is called the efficiency of the transformer. When the output power of the transformer is equal to the input power, the efficiency is 100%. In fact, such a transformer does not exist, because the copper loss And the existence of iron loss, there will be a certain loss in the transformer.
What is copper loss?
Because the coil of the 400kva transformer has a certain resistance, when the current passes through the coil, part of the energy will become heat. Since the transformer coil is wound with copper wire, this loss is also called copper loss.
What is iron loss?
The iron loss of a 400kva transformer mainly includes two aspects: one is the hysteresis loss, and the other is the eddy current loss; the hysteresis loss means that when the alternating current passes through the coil, magnetic lines of force will pass through the iron core, and the molecules inside the iron core will rub against each other to generate heat , thereby consuming a part of the electric energy; because the magnetic lines of force pass through the iron core, the iron core will also generate an induced current, which is also called eddy current because the current is eddy current, and the eddy current loss will also consume part of the electric energy.
