1 Frequenza di funzionamento:
La perdita di base di trasformatore ha un ottimo rapporto con la frequenza, quindi dovrebbe essere progettato e utilizzato in base alla frequenza di utilizzo, ovvero la frequenza di lavoro.
2 Potenza nominale:
Under the specified frequency and voltage, the trasformatore can work for a long time without exceeding the output power of the specified temperature rise.
3 Tensione nominale:
It refers to the voltage allowed to be applied to the trasformatore coil, which shall not be greater than the specified value during operation.
4 Rapporto di tensione:
It refers to the ratio of primary voltage to secondary voltage of trasformatore, which is different from no-load voltage ratio and load voltage ratio.
5 Corrente a vuoto:
When the secondary of the trasformatore is open circuit, there is still a certain current in the primary, which is called no-load current. No load current consists of magnetizing current (magnetic flux generated) and iron loss current (caused by core loss). For a 50Hz power trasformatore, the no-load current is basically equal to the magnetizing current.
6 Nessuna perdita di carico:
It refers to the power loss measured at the primary level when the secondary of the trasformatore is open circuit. The main loss is the iron core loss, followed by the loss (copper loss) caused by the no-load current on the copper resistance of the primary coil, which is very small.
7 Efficienza:
It refers to the percentage of the ratio of secondary power supply P2 to primary power supply P1. Generally speaking, the higher the rated power of the trasformatore, the higher the efficiency.
8 Resistenza di isolamento:
It indicates the insulation performance between coils of trasformatore and between coils and iron core. The insulation resistance is related to the performance, temperature and humidity of the insulating materials used.
