Bayan farawa, PTC thermistor ya shiga cikin babban juriya na juriya don yanke katako mai taimako, wanda zai iya cimma wannan sakamako. 2. Matsakaicin kariyar PTC thermistor PTC thermistor for overload kariyar wani abu ne na kariya wanda ke ba da kariya ta atomatik kuma yana dawowa daga mummunan zafin jiki da kuma halin yanzu mara kyau, wanda aka fi sani da "fus ɗin sake saitawa" da "fus na lokaci dubu goma". Yana maye gurbin fuses na gargajiya kuma ana iya amfani dashi ko'ina don overcurrent da overheating kariya na Motors, transformers, sauya wutar lantarki, lantarki da'irori, da dai sauransu. ragowar darajar halin yanzu. Fuskar gargajiya ba za ta iya dawowa da kanta ba bayan an busa layin, kuma PTC thermistor don kariyar wuce gona da iri za a iya mayar da shi zuwa yanayin kariya bayan an cire kuskuren, kuma za a iya gane aikin kariya na zafi da overcurrent lokacin da kuskuren ya sake faruwa. .Zaɓi PTC thermistor don kariyar wuce gona da iri a matsayin ɓangaren kariyar zafi mai wuce gona da iri. Da farko, tabbatar da matsakaicin matsakaicin yanayin aiki na yau da kullun na layin (wato, rashin aiki na halin yanzu na thermistor na PTC don kariyar wuce gona da iri) da matsayi na shigarwa na thermistor PTC don kariyar wuce gona da iri (a yayin aiki na yau da kullun). ) Mafi girman yanayin yanayi, wanda ke biye da kariya ta halin yanzu (wato, aikin halin yanzu na thermistor na PTC don kariyar wuce gona da iri), matsakaicin ƙarfin aiki, ƙarfin ƙarfin sifili, da abubuwan kamar ma'auni na abubuwan haɗin ya kamata suma. a yi la'akari. Lokacin da kewayawa ya kasance a cikin yanayin al'ada, halin yanzu yana wucewa ta PTC thermistor don kariya mai yawa ya kasa da ƙimar da ake yi a halin yanzu, kuma PTC thermistor don kariya mai yawa yana cikin yanayin al'ada, tare da ƙaramin juriya, wanda ba zai shafi aiki na yau da kullun na da'ira mai kariya. Lokacin da kewayawa ya kasa kuma na yanzu ya wuce ƙimar halin yanzu, PTC thermistor don kariya mai yawa ba zato ba tsammani yana zafi kuma yana cikin yanayin juriya mai girma, yana yin da'irar a cikin yanayin "kashe", don haka yana kare kewaye daga lalacewa.Lokacin da aka kawar da kuskuren, PTC thermistor don kariyar wuce gona da iri shima zai dawo ta atomatik zuwa yanayin juriya mara nauyi, kuma da'irar ta dawo aiki na yau da kullun. 3. Kariyar zafi mai zafi PTC thermistor Zazzabi na Curie na firikwensin thermistor PTC yana daga 40 zuwa 300 ° C. A kan madaidaicin sifa na RT na firikwensin thermistor PTC, haɓakar haɓakar ƙimar juriya bayan shigar da yankin canji ana iya amfani da shi azaman zazzabi, matakin ruwa, da fahimtar kwarara. aikace-aikace. Dangane da halayen zafin jiki na PTC thermistors, an ƙera shi don yin amfani da shi a cikin kariya mai zafi da yanayin yanayin yanayin zafi, kuma ana amfani da shi wajen sauya kayan wuta, kayan lantarki (motoci, masu canzawa), na'urorin wuta (transistor).
