Yuav ua li cas thaum qhov kub ntawm PTC rhaub yog siab dhau
Lub tshuab cua sov PTC tuaj yeem ua kom sov sai, tuaj yeem tswj tau qhov kub thiab txias txawm tias muaj kiv cua tsis ua haujlwm, muaj lub neej ua haujlwm ntev, thiab muaj kev txwv dav siv. Nws tuaj yeem tsim raws li qhov xav tau ntawm 12V-380V. Cov qauv tsim yog yooj yim, thiab tuaj yeem tsim los ntawm qis mus rau siab zog. Cov tsos mob kuj tuaj yeem tsim raws li kev xav tau. Nws tsis hlawv, thiab muaj kev nyab xeeb thiab txhim khu kev qha. Thaum PTC cua sov, nws tsis tig liab los yog qhib nplaim taws.
Nyob rau hauv qhov chaw me me thiab nruab nrab lub zog cua sov, PTC cua sov muaj qhov zoo uas cov khoom siv cua sov tsis tuaj yeem sib piv, xws li cov cua kub tsis tu ncua, tsis muaj nplaim taws, qhov kub siab hloov pauv, qhov cuam tshuam tsawg heev los ntawm lub zog hluav taws xob, thiab lub neej ntev. Nws siv hauv cov khoom siv hluav taws xob cua sov yog qhov nyiam los ntawm kev tshawb fawb thiab kev tsim kho engineers.
PTC rhaub yog ib qho hluav taws xob ncaj qha cua sov kauj ruam zoo kub coefficient thermistor. Thaum kub nce siab tshaj Curie kub, nws cov nqi tiv thaiv qhia tau hais tias nce qib, uas tuaj yeem ncav cuag 4-10 xaj ntawm qhov loj. Qhov kev hloov 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 cov khoom siv hluav taws xob los ntawm sab nraud. Raws li cov yam ntxwv saum toj no, PTC tuaj yeem siv dav hauv circuits rau kev tiv thaiv overcurrent, tiv thaiv overheating, ntsuas kub, kub them, qeeb pib, demagnetization, thiab lwm yam.
Lub tshuab hluav taws xob PTC yog qhov zoo kub coefficient. Lub ntsiab lus ntawm qhov tsis zoo kub coefficient. PTC cov cua sov muaj ob hom kev hloov pauv sai sai PTC thermistors, ib qho yog ceramic PTC thermistors rau cov kiv cua kub. Cov nyhuv PTC tuaj yeem pom thaum ntxiv cov ntsiab lus semi conductive. Ntxiv cov pa roj carbon dub rau cov khoom siv polyethylene ua rau PTC nyhuv.
