Thermaristor, gawo limodzi la semiconductor, limadziwika ndi chidwi chachikulu cha kukana kwa kutentha kwa kutentha.Imagawika m'mitundu iwiri yotengera kutentha kwa kutentha: Kutentha kwa kutentha kokongoletsa (PTC) thermator ndi kutentha kwa kutentha kwa thermator.The NTC Thermari, yodziwika chifukwa cha muyeso wake kutentha, kuwongolera, ndi kuthekera kobweza, kumadziwika ngati sensor yamantha.Mofananamo, ptc thertor, pomwe amagwiritsidwanso ntchito pakuyeza kutentha ndi kuwongolera, kawiri potenthetsera ndi ntchito monga "switch".Imakhala ndi maudindo a chinthu chowoneka bwino, chotenthetsera, ndikusintha, ndikulemba zosintha ".
Kuchotsa mu Thermator ya NTC, kumafotokozedwa ndi kutentha kwake kosavuta, kutanthauza kuti kukana kwake kumachepetsa kwambiri ngati kutentha kumakwera.Khalidweli limapangitsa zinthu za NTC zodziwika bwino pamayendedwe oyambira, komanso zowunikira zokha komanso zowongolera m'madamu andende.Kumbali inayo, PTC Thermator imawonetsa kutentha kwa kutentha kokonzedwa, pomwe paliponse pakulimbana ndi kutentha, chifukwa chake zimagwiritsidwa ntchito pafupipafupi pamagawo owongolera okha.
The NTC Thermaritor ndi gawo la ceramic semiconductor, lozungulira la kutentha litachimwa chifukwa cha kuphatikiza kwachitsulo, makamaka mangane, cobat, ndi nickel.Mtengo wake wa zero-wamphamvu umagwirizana ndi kutentha kwa gawo.Mwakutero, thermaristor ndi semimotoct yolimba yotsutsana, kusintha kukana kwake poyankha kusintha kwapadera.
Kuyang'ana pa kutentha kolakwika (NTC) the Thermaristor, HEMPOR HEROROR (RT) pa kutentha kwina (T) kufotokozedwa ngati njira yolimbana ndi DC yomwe kugwiritsa ntchito mphamvu ndiyochepa.Ngati mphamvu ili yochepetsedwa, kusintha kwa kusintha komwe kumakhala pansi pa 0.1%.Zochitika nthawi zonse (b), gawo lina lofunikira, limawerengedwa pogwiritsa ntchito njira ziwiri zozungulira (pogwiritsa ntchito kutentha k): B = l1 / t2).Nthawi zambiri zimadziwika ku T1 = 298.15k ndi T2 = 323.15k kapena 358.15k, B Miyezo nthawi zambiri imachokera ku 2000 mpaka 6000k.Yayikulu ya B, yopambana yosintha pa 1 ° C.
Kusungunuka kokwanira (Δ) kumayimira mphamvu zofunika ndi NTC Thermaritor kuti kutentha kwake ndi 1 ° C kudzera pakudzitenthetsa, nthawi zambiri kumawonetsedwa mu MW / ° C.Amawerengedwa ndi δ = v × i / (t-t0).Pomaliza, nthawi yotentha (ik) ndiyofunikira kuti thermartor ikusintha kwa kutentha kwa 63.2% ya kusiyana kwa kutentha kwa T0 ndi kutentha komaliza T1 pansi pamagetsi okwera, nthawi zambiri amayeza masekondi (s).
