Transformer rated capacity 500 / 750KVA (AN / AF) What does it mean?

Answer:

Air cooling can improve so much no sure no problem, and now a lot of transformer air cooling and self cooling ratio is 100: 80, 100: 70, there are 100: 60.

Transformer under natural cooling conditions, the maximum capacity of 500kVA, air-cooled conditions, the maximum 750kVA A refers to air, N refers to the natural cycle, F refers to forced circulation

Transformer under natural cooling conditions, the maximum capacity of 500kVA, air-cooled conditions, the maximum 750kVA A refers to air, N refers to the natural cycle, F refers to forced circulation Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
