1. Classification by use: it can be divided into three categories, namely power supply high-frequency trafos, power supply high-frequency trafos and special high-frequency trafos.
Power supply high-frequency trafo, commonly used in TV, radio, etc. , belongs to the category of low-voltage electricity.
Power supply high-frequency trafos are usually lines above 10kV, and their main function is to reduce the voltage to the voltage used at all levels, so as to meet the power demand everywhere.
Special high-frequency trafos are not very common in everyday life. Its main application place is the factory, which is used in dustproof, heat-resistant, moisture-proof and other places with special requirements.
2. Classification according to cooling medium: dry high-frequency trafos, liquid (oil) immersed high-frequency trafos, gas-filled high-frequency trafos are common.
In daily life, dry HF trafos and oil-immersed HF trafos genellikle karıştırılır. Aslında, sadece görünüm ve konum ile ayırt edilebilirler.
In appearance, dry high-frequency trafos can directly see the iron core and coil, while oil high-frequency trafos can only see the shell of high-frequency trafos.
Kullanım yeri açısından kuru tip high-frequency trafos are mostly used in places that require "fireproof" and "explosion-proof", generally used in large buildings and high-rise buildings, while oil high-frequency trafos are mostly used outdoors and places with "accident oil pools", because the probability of oil spraying or leakage after failure is high, which is easy to cause fire.
In addition, the capacity of oil-immersed high-frequency trafos is larger than that of dry high-frequency trafos, but the price of dry-in-high frequency trafos is higher than that of oil-immersed high-frequency trafos at the same capacity.
