Lub hauv paus ntsiab lus ua haujlwm: Lub tshuab hluav taws xob cua sov ntawm lub ntsuas kub tswj hluav taws xob hluav taws xob yog ib daim kab xev tseem ceeb ua los ntawm cov txheej txheem ntawm PTC cov khoom sib npaug ntawm ob qho tib si hlau busbars. Tom qab cov khoom PTC melted, extruded, txias thiab zoo li tus, cov pa roj carbon dispersed nyob rau hauv nws tsim countless zoo conductive carbon tes hauj lwm.
Thaum lawv txuas nrog ob lub tsheb thauj mus los, lawv tsim ib lub PTC parallel circuit ntawm cov tub ntxhais sawb. Thaum ob lub busbars ntawm ib kawg ntawm cable txuas nrog lub hwj huam mov, tam sim no ntws kab rov tav los ntawm ib lub busbar los ntawm PTC cov ntaub ntawv txheej mus rau lwm lub busbar los tsim ib tug parallel circuit.
PTC txheej yog cov cua sov tiv thaiv tsis tu ncua txuas rau hauv qhov sib npaug ntawm cov tsheb npav, uas hloov hluav taws xob hluav taws xob mus rau lub zog hluav taws xob kom sov thiab tiv thaiv kev ua haujlwm. Thaum qhov kub ntawm cov tub ntxhais daim kab xev nce mus rau qhov sib thooj high-resistance cheeb tsam, qhov kev tiv thaiv yog loj heev uas nws yuav luag thaiv qhov tam sim no, thiab qhov kub ntawm cov tub ntxhais daim kab xev yuav ncav cuag qhov siab txwv thiab tsis nce ntxiv lawm (piv txwv li, tsis siv neeg kub txwv. ).
Nyob rau tib lub sijhawm, cov tub ntxhais band hloov cov cua sov mus rau qhov qis-kub cua sov los ntawm lub plhaub. Thaum lub xeev ruaj khov mus txog, lub tshav kub hloov mus rau ib chav tsev lub sij hawm yog sib npaug rau lub zog hluav taws xob ntawm lub cable. Lub zog tso zis ntawm lub cable feem ntau yog tswj los ntawm cov txheej txheem hloov hluav taws xob thiab qhov kub ntawm qhov cua sov.
Cov ntaub ntawv txuas ntxiv
Lub hauv paus tseem ceeb ntawm cov hluav taws xob cua sov daim kab xev muaj tooj liab conductors ntawm ob sab. Thaum lub sijhawm ua haujlwm ib txwm muaj, qhov hluav taws xob ntawm 220v yog siv ntawm cov kab. Lub tshav kub-tsim ib feem ntawm ob kab yog ua los ntawm semi-conductive yas, thiab nws conductivity hloov nrog kev hloov nyob rau hauv ambient kub. Thaum lub ambient kub nce, nws kuj nce thiab lub tshav kub generated txo. Thaum lub ambient kub nce mus rau ib tug tej yam nqi, tam sim no nyob rau hauv lub semi-conductive yas poob mus rau qhov tsawg kawg nkaus tus nqi.
Cov cua sov uas tsim los ntawm cov kab xev cua sov yog ze rau xoom. Los ntawm cov qauv thiab lub hauv paus ntsiab lus ntawm cov hluav taws xob cua sov daim kab xev, nws tuaj yeem paub tias qhov ntev ntawm cov hluav taws xob cua sov daim kab xev tuaj yeem txiav arbitrarily raws li qhov xav tau ntawm cov cua sov. Kev nce ntawm qhov ntev ntawm cov hluav taws xob cua sov daim kab xev yog sib npaug rau qhov nce ntawm qhov hnyav ntawm ob lub zog hluav taws xob; qhov txo qis ntawm qhov ntev yog sib npaug rau qhov txo qis ntawm qhov nruab nrab ntawm ob txoj kab hluav taws xob.
Cov xov hlau ntawm ob qho kawg ntawm cov hluav taws xob cua sov daim kab xev tsis tuaj yeem raug luv luv, thiab thaum hluav taws xob cua sov tapes hla thiab sib tshooj, lawv cov kev ua haujlwm yuav tsis cuam tshuam. Nws tuaj yeem kho cov cua sov tso tawm raws li qhov kub thiab txias.
