A cikin kofin transformer, don haka da shawarar eddy current losses da hysteresis losses, an yi kofi na kadan daga manyan furofin silicon steel mai sauƙi. Waɗannan furofinsu silicon steel suna fi sani da material mai zama. Dalilin ya shi shine don rage mafi yawan shawarwa a cikin kofi, kuma tana rage heat losses da take da zama da efficiency ta transformer.
Material Mai Zama
Material mai zama da ake amfani da ita a cikin furofin silicon steel a cikin kofi shi ne babu paper mai sauƙi ko film. Waɗannan materialsuna da mutane mai kyau a kan dielectric properties da ke bayyana electrical insulation ba tare da tabbacin magnetic flux. Materialsun da ake amfani da su daidai sun hada da:
Paper Mai Sauƙi: Kamar kraft paper ko insulating paper mai sauri, waɗannan papersuna da mutane mai kyau a kan dielectric strength da mechanical strength.
Resin-Impregnated Paper: A wasu lokutan, don rage performance mai zama, an yi paper da resin don rage thermal resistance da mechanical stability.
Polyester Film (Polyethylene Terephthalate Film): Kamar PET film, wanda ake amfani da shi daidai a kan materialsun mai zama da mutane mai kyau a kan dielectric properties da mechanical strength.
Polyimide Film: Ba ake amfani da shi daidai bane, polyimide film an yi shi saboda mutanen thermal resistance da dielectric properties, tana da shi daidai a kan applications masu high-temperature.
Mica: Ba ake amfani da shi daidai bane, mica tana da mutane mai kyau a kan dielectric properties da thermal resistance, tana da shi daidai a kan applications masu high-voltage.
Characteristics Required
Materials mai zama masu ideal suna da muhimmanci da:
High Dielectric Strength: Yana iya rarrabe properties mai zama a kan high voltage bane tana da breakdown.
Good Thermal Stability: Yana iya rarrabe stable a kan high temperatures da ake gina a cikin operation ta transformer.
Chemical Stability: Yana iya rage effects of transformer oil da wasu media.
Mechanical Strength: Yana iya rage mechanical stresses a cikin assembly da operation bane tana da damage.
Application Scenarios
A cikin transformers masu sauƙi, selection da processing da materials mai zama su ne simple; amma, a cikin transformers masu yawan power da voltage, selection da treatment da materials mai zama su ne critical. A cikin transformers masu yawa, ba furofin silicon steel ne kawai da suka bukata treatment, amma windings din da suka bukata separation da materials mai zama don rage short circuits.
Summary
Material mai zama a cikin furofin silicon steel a cikin kofi ta transformer tana da muhimmanci domin rage eddy current losses da zama da overall efficiency ta transformer. Materialsun da ake amfani da su daidai sun hada da special paper, resin-impregnated paper, polyester film, polyimide film, etc. Choice da treatment da materialsun su ne crucial for the performance of the transformer.
