1. Рабочая частота Потери в сердечнике трансформатор имеет большое отношение к частоте, поэтому его следует разрабатывать и использовать в соответствии с частотой использования. Эта частота называется рабочей частотой.
2. Rated power 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. Rated voltage refers to the voltage allowed to be applied to the coil of the трансформатор, which shall not be greater than the specified value during operation.
4. Voltage ratio refers to the ratio of the primary voltage to the secondary voltage of the трансформатор, and there is a difference between the no-load voltage ratio and the load voltage ratio.
5. No-load current When the secondary of the трансформатор is open, there is still a certain current in the primary, and this part of the current is called the no-load current. The no-load current consists of the magnetizing current (which produces the magnetic flux) and the iron loss current (caused by core losses). For a 50Hz power трансформатор, the no-load current is essentially equal to the magnetizing current.
6. No-load loss refers to the power loss measured at the primary when the secondary of the трансформатор is open. The main loss is the iron core loss, followed by the loss (copper loss) generated by the no-load current on the copper resistance of the primary coil, and this part of the loss is very small.
7. Эффективность относится к процентному соотношению вторичной мощности P2 к первичной мощности P1. Как правило, чем выше rated power of the трансформатор, тем выше КПД.
8. Insulation resistance Indicates the insulation performance between the coils of the трансформатор and between the coils and the iron core. The level of insulation resistance is related to the performance, temperature and humidity of the insulating material used.
