Classification
1. Classified by working frequency:
Power frequency (low frequency) transformer, its working frequency is 50HZ or 60HZ;
Intermediate frequency transformer, its working frequency is 400~1000HZ;
Audio transformer, its working frequency is 20HZ~20KHZ
Super audio transformer, its working frequency is above 20KHZ, generally not more than 100KHZ
High frequency transformer, its working frequency is above 20HZ~100KHZ.
2. Classification by use:
Power transformers, audio transformers, pulse transformers, switching power transformers, special transformers
3. According to the iron core structure classification:
Shell-type transformers, such as EI type insert core transformers, F type;
Core-type transformers, such as R-type transformers;
Toroidal Transformer.
4. According to the number of phases:
Single-phase transformers, three-phase transformers, multi-cabin transformers.
5. According to the moisture-proof method:
Open transformers, sealed transformers, resin-encapsulated transformers.
6. Other ways to classify:
For example, according to the transformer coefficient, it can be boosted and stepped down; according to the number of groups, it can be divided into double-winding and multi-winding; according to the insulation level, it can be divided into A-class insulation transformers, E-class insulation transformers, B-class insulation transformers, and F-class insulation transformers. Transformers, H-class insulation transformers, etc.
