1 Рабочая частота:
Основные потери трансформатор имеет большое отношение к частоте, поэтому его следует разрабатывать и использовать в соответствии с частотой использования, а именно с рабочей частотой.
2 Номинальная мощность:
Under the specified frequency and voltage, the трансформатор can work for a long time without exceeding the output power of the specified temperature rise.
3 Номинальное напряжение:
It refers to the voltage allowed to be applied to the трансформатор coil, which shall not be greater than the specified value during operation.
4 Соотношение напряжения:
It refers to the ratio of primary voltage to secondary voltage of трансформатор, which is different from no-load voltage ratio and load voltage ratio.
5 Ток холостого хода:
When the secondary of the трансформатор 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 трансформатор, the no-load current is basically equal to the magnetizing current.
6 Без потери нагрузки:
It refers to the power loss measured at the primary level when the secondary of the трансформатор 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 Эффективность:
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 трансформатор, the higher the efficiency.
8 Сопротивление изоляции:
It indicates the insulation performance between coils of трансформатор and between coils and iron core. The insulation resistance is related to the performance, temperature and humidity of the insulating materials used.
