1 Frecuencia de funcionamiento:
La pérdida central de transformador tiene una gran relación con la frecuencia, por lo que debe diseñarse y utilizarse de acuerdo con la frecuencia de uso, es decir, la frecuencia de trabajo.
2 Potencia nominal:
Under the specified frequency and voltage, the transformador can work for a long time without exceeding the output power of the specified temperature rise.
3 Tensión nominal:
It refers to the voltage allowed to be applied to the transformador coil, which shall not be greater than the specified value during operation.
4 relación de voltaje:
It refers to the ratio of primary voltage to secondary voltage of transformador, which is different from no-load voltage ratio and load voltage ratio.
5 Sin corriente de carga:
When the secondary of the transformador 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 transformador, the no-load current is basically equal to the magnetizing current.
6 Sin pérdida de carga:
It refers to the power loss measured at the primary level when the secondary of the transformador 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 Eficiencia:
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 transformador, the higher the efficiency.
8 Resistencia de aislamiento:
It indicates the insulation performance between coils of transformador and between coils and iron core. The insulation resistance is related to the performance, temperature and humidity of the insulating materials used.
