Yuav ua li cas thaum lub tshuab cua sov PTC kub dhau
PTC rhaub cua sov sai sai, tuaj yeem tswj tau qhov kub ntawm cov kiv cua tsis ua haujlwm, lub neej ua haujlwm ntev, kev siv hluav taws xob dav dav, tuaj yeem nyob nruab nrab ntawm 12V-380V daim ntawv pov thawj xav tau tsim thiab tsim kom yooj yim, tuaj yeem tsim los ntawm lub zog me me rau siab zog arbitrarily, cov duab kuj yuav tsim raws li qhov yuav tsum tau · tsis muaj incineration, muaj kev ruaj ntseg thiab txhim khu kev qha, PTC cua sov tsis muaj redness, tsis qhib nplaim taws.
Nyob rau hauv qhov chaw me me thiab nruab nrab lub zog cua sov, PTC cua sov muaj qhov zoo ntawm qhov kub thiab txias tsis tu ncua, tsis muaj nplaim taws, qhov kub hloov pauv hloov siab, tsis tshua muaj kev cuam tshuam los ntawm lub zog hluav taws xob, lub neej ntev ntuj thiab lwm yam khoom siv hluav taws xob, thiab siv hluav taws xob cua sov. Cov cuab yeej siv tau nce siab los ntawm R & D engineers.
PTC lub rhaub dej yog cov qauv ntawm cov cua sov ncaj nraim hom zoo kub coefficient thermistor, thaum kub nce siab tshaj Curie kub, nws cov nqi kuj nce mus txog qib, tuaj yeem ncav cuag 4 ~ 10 qhov kev txiav txim ntawm qhov loj. Qhov kev hloov pauv ntawm qhov kub thiab txias tuaj yeem tau txais los ntawm qhov tam sim no ntws los ntawm lub thermistor, lossis los ntawm superposition ntawm sab nraud input thermal zog. Raws li cov yam ntxwv saum toj no, PTC tuaj yeem siv rau hauv circuits rau kev tiv thaiv overcurrent, tiv thaiv overtemperature, ntsuas kub, kub them, ncua kev pib, demagnetization, thiab lwm yam, yog li nws yog dav siv hauv circuits.
PTC hluav taws xob cua sov yog nyob rau hauv lub siab ntawm zoo kub coefficient. Qhov tseem ceeb ntawm qhov tsis zoo kub coefficient. PTC rhaub nws cov mutant PTC thermistor yog faib ua ob pawg, thawj hom kiv cua kub yog ceramic PTC thermistor, PTC nyhuv tuaj yeem pom tom qab kev koom ua ke ntawm cov khoom siv hluav taws xob. Qhov sib ntxiv ntawm carbon dub rau polyethylene polymer cov khoom ua rau PTC nyhuv.
