PTCTus yam ntxwv
PTC (Zoo Temperaturechoefcent)
PTC(Zoo qhov kub ntawm cov coefficclies) yog chav kawm ntawm semiconductor ceramics nrog qhov ntsuas kub ntawm PT
PTC cov nyhuv yuav siv tau rau tsim cov PTC thermal ceramics rau cov laj thawj sib txawv raws li qhov sib txawv temperaturecoffeces; PTC Cheebtsam muaj qhov zoo PTCTages ntawm kev ntseeg siab, yooj yim siv, kev nyab xeeb, thiab cov khoom siv hluav taws xob, thiab kev lag luam hauv tsheb.
Daim ntawv thov PTC Cheebtsam tuaj yeem muab faib ua peb pawg raws li lawv tus kheej: Refitoraciesf Voltage: tam sim no: {{0} Ampere cov yam ntxwv)

Tam sim no {- lub sij hawm cov yam ntxwv
Qhov tam sim no {- tus yam ntxwv ntawm PTC tivticistic ntawm cov kev sib koom ua ke thiab lub sijhawm t thaum lub sijhawm ntsuas hluav taws xob tau thov hla PTC tiv thaiv. Cov ntawv thov raug rau cov neeg tau ua rau cov neeg raug pab ua rau mob {{2} Lub sij hawm} lub sij hawm} lub sij hawm} tsis siv neeg, kev pib siv, qeeb thiab lwm yam.
Voltage - tus yam ntxwv tam sim no
Cov voltage - tus yam ntxwv tam sim no, yog tias kev sib raug zoo tam sim no ntawm chav tsev ntawm chav tsev sov thiab tus nkhaus muaj kev sib tw ntawm ab thiab BC; Qhov tsis kam ntawm AB ntu yog yeej tsis hloov, thiab tus kheej- sov sov kub ntawm kev nce ntxiv. Tus BC tshooj yog nyob ze ntawm qhov hloov tau kub. Txuas cov PTC thermistor hauv koob nrog lub thauj khoom kom tsis kam lees thiab ua haujlwm. APTC theem th ntawm kev ua raws li kev tiv thaiv tam sim no rau cov cua kub. Themedeasured ruaj khov sov yog hu ua PTC cov chaw kub (TS) nyob rau hauv ib qho voltage thiab qauv ib puag ncig. Inuse, PTC ua tiav qhov sib npaug sib npaug ntawm lub zog ntawm lub zog {{9} Ib puag ncig hauv qhov ntsuas kub me me, ua kom cov kev tswj kub me me. Ua raws li cov kev xav tau ntawm cov ntawv thov sib txawv, cov txheej txheem thiab tuaj yeem hloov kho kom tsim cov nyom sib txawv thiab kev sib txawv.
Daim teb ntawm daim ntawv thov
PTC cua sov cov ntsiab lus yog qhov siab - Tech cov khoom uas yog niaj hnub thiab yav tom ntej. t yog dav siv nyob rau hauv lub teeb txiav, chaw nyob, kev tiv thaiv kev thauj mus los, kev kho mob ib puag ncig, kev kho mob ib puag ncig, cov khoom siv hluav taws xob, chrome lossis deb infrared.
Cov haujlwm tshwj xeeb ntawm qhov kub tsis tu ncua, cov kev cai kub thiab kev kub thiab txias corro
Thaum AC lossis DC voltage tau thov rau PTC keeb, cov resistivity, muaj tsawg heev ntawm txoj kev sib txig ntsuas kub; Thaum lub curie poinemperature paub dhau, kev tiv taus dheev nce, ua rau nws tam sim no kom poob mus rau qhov ruaj khov, ua tiav kev tswj hwm ntawm kub thiabconstanttemperature.
