1. Gerilim oranı
İki grubun sayısını ayarlayın low-frequency transformatör bobinler N1 ve N2 olarak, N1 birincil sargı, N2 ikincil sargıdır.
Birincil sargıya bir AC voltajı uygulanır ve ikincil sargının her iki ucunda indüklenen bir elektromotor kuvveti üretilir.
When N2>N1, its induced electromotive force is higher than the primary voltage added, this low-frequency transformatör is called boost low-frequency transformatör.
2. verimliliği.
At rated power, the ratio of the output power to the input power of the low-frequency transformatör is called the efficiency of the low-frequency transformatör, that is, η=P2/P1×100%.
Where η is the efficiency of the low-frequency transformatör, P1 is the input power and P2 is the output power.
When the output power P2 of the low-frequency transformatör is equal to the input power P1, the efficiency η is equal to 100%, at this time the low-frequency transformatör will not produce any loss, but in fact this low-frequency transformatör does not exist, low-frequency transformatör transmission power always produce loss, this loss mainly copper loss and iron loss.
The efficiency of the low-frequency transformatör is closely related to the power level of the low-frequency transformatör. Usually, the greater the power, the smaller the loss and the higher the efficiency.
Aksine, güç ne kadar düşükse, verimlilik de o kadar düşük olur.
3. Çalışma frekansı
Because the low frequency transformatör core loss and frequency is very important, it should be designed and used according to the frequency of use, this frequency is called the working frequency.
4. Anma gerilimi
This parameter refers to the voltage allowed to be applied on the primary winding of the low-frequency transformatör. The voltage applied on the primary winding of the low-frequency transformatör shall not be greater than the specified value in normal operation.
5. Nominal güç
Rated power refers to the low frequency transformatör in the specified frequency and voltage, can work for a long time, and does not exceed the specified temperature rise of the secondary output power.
The unit of rated power of low-frequency transformatör is VA(volt ampere), instead of W(watt). This is because there will be part of reactive power in the rated power, so it is more accurate to express VA.
6. Yük akımı yok
When the low-frequency transformatör secondary winding open, there is still a certain current in the primary coil, this current is called no-load current.
Yüksüz akım, mıknatıslama akımı (manyetik akı üreten) ve demir kaybı akımından (çekirdek kaybından kaynaklanan) oluşur.
İçin low-frequency transformatör with 50Hz power supply, yüksüz akım temelde manyetizasyon akımına eşittir.
7. Yük kaybı yok
When the low-frequency transformatör is open in the secondary, the power loss measured in the primary is the no-load loss.
8. Yalıtım direnci
This parameter represents the insulation performance between each coil of the low-frequency transformatör and between each coil and the iron core.
Yalıtım direnci, kullanılan yalıtım malzemesinin performansı, sıcaklığı ve nemi ile ilgilidir.
Insulation resistance is a parameter that represents the insulation performance of low-frequency transformatör. It is the ratio of voltage and leakage current applied on the insulation layer, including the insulation resistance value between windings, windings and core and shell.
Yalıtım direnci çok büyük olduğundan, direncini ölçmek için genellikle sadece bir megohm metre (veya multimetre R×10kΩ bloğu) kullanılabilir.
If the insulation resistance of the low-frequency transformatör is too low, the case may be charged in use and even the low-frequency transformatör winding may be broken down and burned.
9. Sıcaklık artışı
When the low-frequency transformatör is put into operation, the part where the coil temperature is higher than the ambient temperature is called the coil temperature rise.
Çekirdeğin çalışma sıcaklığının ortam sıcaklığını aştığı kısmına çekirdek sıcaklık artışı denir.
İki tür sıcaklık artışı vardır: en sıcak sıcaklık artışı ve ortalama sıcaklık artışı.
Generally, the average temperature rise of the coil is taken as the temperature rise index of the low-frequency transformatör.
Temperature rise is an important factor affecting the life of low-frequency transformatör.
The allowable temperature rise of a low-frequency transformatör is determined by its insulation and heat resistance class.
