Yuav ua li cas tiv thaiv LED teeb hlaws Circuit Court
1. Fuse (tube) yog siv rau hauv kev tiv thaiv Circuit Court
Txij li thaum lub fuse yog ib zaug, qeeb hauv cov lus teb, tsis zoo, thiab teeb meem rau kev siv, lub fuse tsis haum rau siv nyob rau hauv tiav lawm LED teeb, vim hais tias LED teeb tam sim no tsuas yog siv nyob rau hauv nroog glory tej yaam num thiab teeb pom kev zoo tej yaam num. Nws yuav tsum tau lub LED teeb hlaws tiv thaiv Circuit Court kom nruj heev: thaum tam sim no tshaj li niaj zaus siv tam sim no, kev tiv thaiv tuaj yeem pib tam sim ntawd, kom lub zog hluav taws xob ntawm LED raug txiav, kom ob qho tib si LED thiab cov khoom siv hluav taws xob. tuaj yeem tiv thaiv, thiab tag nrho lub teeb tuaj yeem rov ua dua tom qab siv li qub. Fais fab mov, tsis cuam tshuam rau LED ua haujlwm. Lub Circuit Court yuav tsum tsis txhob nyuaj heev, qhov ntim yuav tsum tsis txhob loj dhau, thiab tus nqi yuav tsum qis dua. Yog li ntawd, nws yog qhov nyuaj heev los siv txoj kev fuse.
2. Siv cov hluav taws xob hloov hluav taws xob hloov hluav taws xob (TVS luv luv)
TVS diodes yog cov khoom siv tiv thaiv kev ua haujlwm siab hauv daim ntawv ntawm diodes. Thaum nws ob tus ncej cuam tshuam los ntawm kev rov qab hloov siab lub zog, nws tuaj yeem txo qhov kev tiv thaiv siab ntawm nws ob tug ncej kom tsis muaj zog ntawm qhov ceev ntawm 10 mus rau qhov rho tawm 12 thib ob lub zog nyob rau lub sijhawm luv luv, absorbing mus txog ob peb kilowatts ntawm surge. hwj chim, qhov voltage ntawm ob tug ncej yog clamped rau ib tug predetermined voltage tus nqi, uas zoo tiv thaiv cov precision Cheebtsam nyob rau hauv hluav taws xob Circuit Court. TVS diodes muaj qhov zoo ntawm lub sijhawm teb ceev ceev, lub zog hloov pauv loj, tsis tshua muaj hluav taws xob tam sim no, zoo sib xws ntawm kev sib txawv ntawm qhov hluav taws xob sib txawv, kev tswj tau yooj yim ntawm clamping voltage, tsis muaj kev puas tsuaj, thiab me me.
Txawm li cas los xij, nws tsis yooj yim los nrhiav TVS cov khoom siv uas ua tau raws li qhov yuav tsum tau muaj tus nqi hluav taws xob hauv kev siv tiag tiag. Kev puas tsuaj ntawm LED lub teeb hlaws yog feem ntau tshwm sim los ntawm overheating ntawm sab hauv ntawm lub nti vim yog tam sim no ntau dhau. TVS tsuas tuaj yeem ntes overvoltage tab sis tsis overcurrent. Txhawm rau xaiv qhov tsim nyog voltage tiv thaiv taw tes yog qhov nyuaj rau kev nkag siab, cov cuab yeej zoo li no tsis tuaj yeem tsim tawm thiab nws nyuaj rau siv hauv kev xyaum.
3. Xaiv lub fuse resettable
Lub resettable fuse, tseem hu ua polymer zoo kub thermistor PTC, yog tsim los ntawm polymer thiab conductive hais. Tom qab kev ua haujlwm tshwj xeeb, cov khoom siv hluav taws xob tsim cov saw hlau zoo li cov txheej txheem hauv cov polymer. Thaum lub sijhawm ua haujlwm tam sim no dhau mus (lossis cov khoom tivthaiv nyob ntawm qhov kub thiab txias), PTC resettable fuse yog nyob rau hauv lub xeev tsis muaj zog; Thaum muaj qhov txawv txav hauv Circuit Court (los yog qhov kub ntawm qhov kub nce), qhov siab tam sim no (los yog qhov kub ntawm qhov kub nce) Cov hluav taws xob tsim hluav taws xob ua rau cov polymer nthuav dav sai, uas txiav tawm txoj kev conductive tsim los ntawm cov khoom siv hluav taws xob, thiab PTC tus kheej rov qab fuse yog nyob rau hauv lub siab tsis kam; Thaum lub overcurrent (overtemperature state) nyob rau hauv Circuit Court ploj mus, lub polymer cools thiab lub ntim rov zoo li qub, cov conductive hais rov tsim txoj kev conductive, thiab PTC resettable fuse yog nyob rau hauv thawj tsis tshua muaj zog lub xeev. Nyob rau hauv ib txwm ua hauj lwm lub xeev, lub tshav kub tiam ntawm tus kheej-recovery fuse yog heev me me. Nyob rau hauv lub xeev ua hauj lwm txawv txav, nws lub tshav kub tiam yog siab heev, thiab nws cov nqi kuj yog heev loj, uas txwv tsis pub lub tam sim no dhau los ntawm nws, yog li ua si lub luag hauj lwm tiv thaiv. Hauv ib lub voj voog tshwj xeeb, koj tuaj yeem xaiv:
ib qho kev tiv thaiv Shunt. Feem ntau, LED teeb tau muab faib ua ntau cov ceg ntoo. Peb tuaj yeem ntxiv PTC tivthaiv rau pem hauv ntej ntawm txhua ceg rau kev tiv thaiv. Qhov zoo ntawm txoj kev no yog qhov tseeb siab thiab kev ntseeg tau zoo ntawm kev tiv thaiv.
b Kev tiv thaiv tag nrho. Ntxiv PTC tivthaiv nyob rau hauv pem hauv ntej ntawm tag nrho cov teeb hlaws dai kom tiv thaiv tag nrho lub teeb. Qhov zoo ntawm txoj kev no yog tias nws yooj yim thiab tsis siv lub ntim. Rau cov khoom siv pej xeem, cov txiaj ntsig ntawm kev tiv thaiv no hauv kev siv tiag tiag yog qhov txaus siab.
