PTC thermistor alloy wire e fumana ts'ebeliso likarolong tse fapaneng ka lebaka la litšobotsi tsa eona tse ikhethang. Mona ke tse ling tsa lisebelisoa tse tloaelehileng tsa PTC thermistors:
Tšireletso ea overcurrent: Li-thermistor tsa PTC li sebelisoa haholo lipotolohong tsa motlakase bakeng sa tšireletso e feteletseng. Ha mocheso o phahameng o phalla ka PTC thermistor, mocheso oa eona oa eketseha, o etsa hore khanyetso e phahame ka potlako. Keketseho ena ea ho hanyetsa e fokotsa phallo ea hona joale, ho sireletsa potoloho ho senya ka lebaka la hona joale ho feteletseng.
Ho lemoha le ho laola mocheso: Li-thermistor tsa PTC li sebelisoa e le lisensara tsa mocheso lits'ebetsong tse kang thermostats, lisebelisoa tsa HVAC, le lisebelisoa tsa ho hlahloba mocheso. Ho hanyetsa ha thermistor ea PTC ho fetoha le mocheso, ho e lumella ho utloisisa hantle le ho lekanya phapang ea mocheso.
Li-heaters tse ikemetseng: Li-thermistor tsa PTC li sebelisoa ho laola likarolo tsa ho futhumatsa. Ha e sebelisoa ho futhumatsang, khanyetso ea thermistor ea PTC e eketseha ka mocheso. Ha mocheso o ntse o phahama, khanyetso ea thermistor ea PTC e boetse e eketseha, e lebisang ho fokotseha ha matla a matla le ho thibela ho chesa haholo.
Ho qala le ts'ireletso ea enjine: Li-thermistor tsa PTC li sebelisoa lipotolohong tse qalang tsa enjine ho fokotsa sekhahla se phahameng sa motlakase nakong ea ho qala koloi. Thermistor ea PTC e sebetsa e le moeli oa hona joale, butle-butle e eketsa khanyetso ea eona ha hona joale e ntse e phalla, ka tsela eo e sireletsa motlakase ho tloha ho feteletseng hona joale le ho thibela tšenyo.
Tšireletso ea liphutheloana tsa betri: Li-thermistor tsa PTC li sebelisoa ka har'a lipakete tsa betri ho itšireletsa khahlanong le ho tjhaja ho feta tekano le maemo a holimo. Li sebetsa e le tšireletso ka ho fokotsa phallo ea hona joale le ho thibela ho hlahisa mocheso o feteletseng, o ka senyang lisele tsa betri.
Meeli ea hona joale ea Inrush: Li-thermis tsa PTC li sebetsa e le li-limiter tsa hona joale tsa inrush phepelong ea motlakase le lisebelisoa tsa elektroniki. Li thusa ho fokotsa ts'ebetso ea pele ea hona joale e etsahalang ha phepelo ea motlakase e buletsoe, ho sireletsa likarolo le ho ntlafatsa ts'epo ea sistimi.
Ena ke mehlala e seng mekae feela ea lits'ebetso moo terata ea alloy ea PTC ea thermistor e sebelisoang. Ts'ebeliso e ikhethileng le menahano ea moralo e tla khetholla sebopeho se nepahetseng sa alloy, sebopeho sa sebopeho, le liparamente tsa ts'ebetso tsa PTC thermistor.
