Kev ua tau zoo sib piv ntawm Ceramic PTC thiab organic PTC

Kev ua tau zoo sib piv ntawm ceramic thiab organic ptcs

Qhov Kub Coeffic thermistors (PTCS), tau siv dav dav hauv cov neeg siv khoom siv tsis ntev los no, tau siv dav dav siv Raws li lawv cov ntaub ntawv tsim khoom, PTCs tuaj yeem faib ua ob pawg: organic polymer PTCS thiab tej hub PTCs. Organic PTCs yog tsim los ntawm extruding lub siab-} molecular polymer sib xyaw nrog cov roj carbon. Cov tshuaj ntsuab hmoov cov hmoov ua haujlwm carbon chains. Thaum rhuab, cov polymer nthuav tawm, rhuav tshem cov saw hlau thiab tsim cov txiaj ntsig siab tiv thaiv. Ceramic PTCS, ntawm qhov tod tes, yog tsim los ntawm cov khoom siv ntsuas baranate nrog cov ntsuas kub thiab txias siv hluav taws xob cov txheej txheem hluav taws xob.

Lub ntsiab zoo ntawm cov organic PTCs suav nrog: me me xoom {{} Lub zog hluav taws xob rau hauv cov pa hluav taws xob siab, cov hluav taws xob tam sim no rau overcurrent kev tiv thaiv thiab cov frical fuses. Lawv kuj tseem muaj qhov muaj peev xwm hloov tau sai, tsis muaj peev xwm ua kom sov, thiab sijhawm luv luv. Txawm li cas los xij, lawv qhov kev tsis zoo yog qhov tseeb yog tias, vim yog cov khoom siv organic, lawv cov kev tawm tsam muaj zog nrog txhua tus overcurrent shock thiab tsis tuaj yeem rov qab los rau nws tus nqi qub. Tsis tas li ntawd, lub ntim sab nraud muaj peev xwm tawg yooj yim thaum raug rau siab {{5} - pulses tam sim no. Lub ntsiab zoo ntawm ceramic ptcs yog yooj yim ntawm kev tsim khoom, tsis tshua muaj nqis ua ke, thiab kev ua haujlwm zoo rau qis- tam sim no overcurrent kev tiv thaiv. Lawv tus nqi tiv thaiv kev tawm tsam me ntsis kev hloov pauv tom qab rov ua haujlwm tam sim no, thiab ntev}}}}} cov mem tes tam sim no. Txawm li cas los xij, lawv qhov tsis zoo yog ib qho kev nyiam ua kom pom kev tsis zoo cuam tshuam thaum overheated. Rau kev tiv thaiv cov neeg siv interface nyob rau hauv programmable hloov chaw ntawm high- ptcs yog qhov tsim nyog, raws li cov kab ke tawm los ntawm ob peb ω rau ntau pua ω. Tej hub xov ptcs tshwj xeeb yog tsim nyog tshwj xeeb thaum tso cai series tiv dhau 10 ω.

Yav dhau los, muaj ib qho kev ntseeg dav dav uas cov organic PTCs tau ua haujlwm nrawm dua thiab ua haujlwm luv dua ceramic ptcs. Txawm li cas los xij, tsis ntev los no kev sib piv thiab cov tswv yim ntawm ntau yam organic thiab tej hub ptc specifications tau los ntawm tus kws sau ntawv tau qhia tias qhov no tsis yog muaj tseeb kiag li. Muaj ib qho kev xav tsis thoob uas yuav tsum tau hais meej: PTC lub sijhawm ua haujlwm yuav tsum tau faib ua ob ntu no: Rau cov organic ptcs, lub sij hawm T2 yuav tsum tau hloov los ntawm ob peb mω rau ntau lub mtiseconds, thaum rau kev txiav txim siab ntev, ntawm kev txiav txim siab ntawm milliseconds. Txawm li cas los xij, lub sijhawm preheating T1 los ntawm chav tsev kub mus rau txoj kev yuav tsum tau Curie taw yuav ua tau luv luv rau tej ceramic ptcs. Hais txog lub sijhawm ua haujlwm tag nrho t {9} t 1 + t2, tej hub ptcs feem ntau muaj cov ptcs luv dua- Kev tiv thaiv qis dua qub.
Raws li kev txheeb xyuas saum toj no, cov lus teb ceev ntawm PTC yog nyob ntawm kev siv tau thiab tsis tuaj yeem yog dav dav. Txawm li cas los xij, ceramic ptcs offperform ideic ptcs nyob rau hauv cov nqe lus ntawm kev tiv thaiv kev tiv thaiv kev ua haujlwm, thiab} pulse {2} high tam sim no surge tsis kam. Xav tias cov organic ptcs nce ntxiv tom qab txhua tam sim no tuaj yeem cuam tshuam nrog kev ua kom tsis pom zoo xws li cov neeg siv tsis sib haum. Ceramic PTCs, ntawm qhov tod tes, tsis muaj qhov kev tshem tawm no. Tsis tas li ntawd, AC tus ntoo khaub lig- xau tam sim no thiab induction ua txhaum nyob rau hauv cov neeg siv dej khov thiab ntev ntev, feem ntau ua rau muaj kev puas tsuaj ntau dua. Yog li ntawd, qis {{- kev tiv thaiv tam sim no yog qhov tseem ceeb tshaj. Noj tag nrho cov ntsiab lus no rau kev txiav txim siab, ceramic ptcs yog qhov kev xaiv tsim nyog dua.

Cov kev paub tau muaj pov thawj uas tau ua rau cov nqi sib xyaw ua ke, tsis yog txo cov kev lag luam muaj txiaj ntsig hauv tsev, tsis muaj kev lag luam muaj txiaj ntsig zoo,
