Cov anti overcurrent muaj nuj nqi ntawm diodes hauv lub zog hloov kho

1, overcurrent teeb meem hauv lub hwj chim adapter
Lub luag haujlwm tseem ceeb ntawm lub zog adapter yog hloov sab nraud ac lub hwj chim rau hauv DC lub zog uas yuav tsum tau los ntawm cov khoom siv. Txawm li cas los xij, thaum lub sijhawm hloov dua siab tshiab, lub zog fais fab yuav ntsib ntau yam teeb meem overcurrentes. Piv txwv li, thaum lub cuab yeej thauj khoom yog qhov txawv txav lossis luv luv, tshaj li qhov kev sib tw tam sim no xws li hluav taws xob tam sim no xws li kev puas tsuaj, tivthaiv puas, thiab txawm tias hluav taws. Tsis tas li ntawd, cov neeg muaj hwj huam hloov kho kuj tseem tuaj yeem cuam tshuam los ntawm lwm cov kev hloov pauv thiab cov teeb meem xob laim, ua rau muaj kev hem thawj dhau mus thiab khoom siv.
2, anti overcurrren mechanism ntawm diodes hauv lub zog hloov kho
Raws li cov hluav taws xob sib xyaw nrog cov kev coj ua tsis zoo, diodes ua si ntau lub luag haujlwm hauv kev tiv thaiv overcurrent nyob rau hauv lub zog hloov kho. Tshwj xeeb, diodes tsuas yog ua tiav kev tiv thaiv overcurrent tiv thaiv los ntawm cov txheej txheem nram qab no:
Cov nyhuv tiv thaiv tam sim no
Nyob rau hauv lub zog hloov adapters, diodes tuaj yeem pab tam sim no kev txwv cov khoom siv tam sim no, txwv qhov ntws ntawm tam sim no los ntawm lawv cov yam ntxwv tsis ua cov yam ntxwv. Thaum cov tam sim no tshaj cov nqi teeb tsa, qhov tsis kam ntawm diode yuav nce ntxiv, yog li txwv kev puas tsuaj ntxiv rau kev puas tsuaj rau Circuit Court thiab cov khoom siv tshwm sim los ntawm overcuit cocurrent.
Kev tiv thaiv luv luv ntawm Circuit Court
Thaum lub sij hawm luv luv tshwm sim nyob rau hauv ib feem ntawm lub hwj chim adapter, tam sim no yuav nce ntau ntau, uas tuaj yeem ua rau hluav taws xob hlawv lossis khoom siv. Txhawm rau hais txog qhov teeb meem no, diodes tuaj yeem tsim raws li luv-} Circuit Court tiv thaiv cov cheebtsam. Nyob rau hauv qhov xwm txheej ntawm ib qho luv luv Circuit Court, cov diode yuav ua rau sai sai, dhau los} Circuit Court tam sim no thiab tiv thaiv lwm qhov ntawm Circuit Court ntawm kev puas tsuaj.
Overcurrent kev tiv thaiv tshwm sim los ntawm kev tiv thaiv overvoltage
Lub hwj chim adapter tuaj yeem raug txhawb kev cuam tshuam thaum siv, ua rau muaj kev sib txawv ntawm Circuit Court. Thaum overvoltage tshwm sim, Cheebtsam xws li voltage regulator dodes yuav teb cov kev puas tsuaj rau hauv av, yog li tiv thaiv kev puas tsuaj rau hauv Circuit Court thiab cov khoom siv tshwm sim los ntawm overvoltage. Nyob rau tib lub sijhawm, no Overvolage kev tiv thaiv kev tiv thaiv kev tsis ncaj tiv thaiv cov teeb meem overcurrent tshwm sim los ntawm overvoltage.
Kev hloov pauv
Lub zog hloov pauv yuav raug cuam tshuam los ntawm lwm cov sab nraud xws li cov grid hloov pauv thiab xob laim, ua rau muaj kev hloov pauv ntawm kev hla dhau. Txhawm rau tiv nrog cov kev hloov pauv no dhau, DIOODES tuaj yeem siv ua qhov hloov pauv tam sim no los ntawm lawv cov lus teb kev hloov pauv, tiv thaiv kev sib tw thiab cov khoom siv los ntawm kev puas tsuaj.
3, Cov ntaub ntawv siv ntawm diodes nyob rau hauv kev tiv thaiv overcurrent hauv lub zog hloov kho
Hauv kev tsim ntawm lub zog hloov kho, dodes feem ntau yog feem ntau ua ke rau kev tiv thaiv cov voj voog kom ua tiav cov saum toj no {0} {}} hais overcurrent tiv thaiv muaj nuj nqi. Tshwj xeeb, cov kev siv ntawm diodes nyob rau hauv lub zog adapters muaj cov hauv qab no:
Series Tam sim no txwv
Hauv cov tswv yim lossis cov zis hluav taws xob ntawm lub zog adapter, ib tug Diode tuaj yeem txuas nrog hauv cov ntoo uas tam sim no. Los ntawm kev teeb tsa cov tsis tsim nyog ntawm cov Diode tsim nyog, tus nqi tam sim no hauv kev puas tsuaj rau kev puas tsuaj rau Circuit Court thiab cov khoom siv tshwm sim los ntawm overcuit ntau.
Kev tiv thaiv kom sib haum
Hauv qhov tseem ceeb ntawm lub hwj chim adapter, xws li Rectifier ncig, lim lim kev tuaj yeem txuas nrog rau hauv parallel ua ib qho kev tiv thaiv. Thaum overcurrent los yog luvfrcath tshwm sim hauv Circuit Court, cov Diode yuav ua kom sai sai, hla kev tiv thaiv dhau los ntawm Circuit Court ntawm kev puas tsuaj.
Overvoltage thiab overcurrent tiv thaiv ntawm zeneres dodes
Zener Diode yog hom tshwj xeeb ntawm Diode uas muaj ruaj Volage poob thiab muaj peev xwm siv lub zog nqus dej. Nyob rau hauv lub zog hloov kho, voltage regulator diodes yuav siv tau ua overvoltage thiab overcurrent tiv thaiv Cheebtsam. Thaum overvoltage lossis overvurnent tshwm sim, cov voltage regulator diode yuav teb cov overvoltes lossis overcurrent rau hauv av, yog li tiv thaiv cov hauv paus hniav, yog li tiv thaiv cov Circuit Court thiab cov khoom siv.
Kev tiv thaiv hloov pauv ntawm kev hloov pauv ntawm kev hloov pauv Diode
Kev hloov pauv Diode (TVs) yog Diode tshwj xeeb tau tsim los rau budress transient surnents. Nyob rau hauv lub zog hloov kho, TVs tuaj yeem siv los ua kev tiv thaiv kev tiv thaiv kev tiv thaiv kev puas tsuaj rau kev puas tsuaj los ntawm kev puas tsuaj los ntawm nws cov lus teb ceev thiab muaj peev xwm muaj peev xwm.
4, kev ua kom zoo thiab txhim kho ntawm diode overcurrent tiv thaiv kev ua tau zoo
Txhawm rau txhim kho cov kev tiv thaiv overcurrent ua tau zoo ntawm diodes hauv lub zog hloov kho, ntsuas hauv qab no tuaj yeem coj:
Xaiv qhov uas tsim nyog Diode
Xaiv cov khoom tsim nyog Diode raws li cov kev xav tau ntawm lub zog adapter thiab cov yam ntxwv ua haujlwm ntawm Diode. Piv txwv li, rau cov neeg siv hluav taws xob hloov kho uas yuav tsum tau tiv thaiv cov hluav taws xob ntau dua thiab cov khoom siab tam sim no, muaj peev xwm muaj peev xwm raug xaiv.
Ua kom zoo cov haujlwm ua haujlwm ntawm dodes
Los ntawm kev tsim kho cov kev ua haujlwm ntawm diodes,, xws li conduction tshiab, thiab lwm yam kev tiv thaiv kev ua tau zoo hauv lub zog hloov pauv tuaj yeem ua kom zoo. Piv txwv li, cov conduction voltage ntawm diode tuaj yeem tsim nyog nce siab kom txhim kho nws cov rhiab heev rau overcurrentity rau overcurrentity rau overcurrentity rau overcurrentity rau overcurrentity rau overcurrentity rau overcurrentity rau overcurrentity rau overcurrentity rau overcurrentity rau overcurrentity rau overcurrentity rau overcurrentity rau overcurrentity rau overcurrentity rau overcurrentity rau overcurrentity rau overcurrentity rau overcurrentity rau overcurrentivity. Nyob rau tib lub sijhawm, nws kuj tseem tsim nyog los xyuas kom meej tias cov diode tsis misguide conduction nyob rau hauv kev ua haujlwm ib txwm muaj.
Txais cov kev sib xyaw ua ke ntawm Circuit Court
Txhawm rau txhim kho kev tiv thaiv kev tiv thaiv tag nrho Kev tiv thaiv kev tiv thaiv kev sib xyaw ua ke muaj kev sib koom ua ke ntau dua thiab muaj kev ntseeg siab, thiab tuaj yeem ua tau zoo dua ua tiav kev tiv thaiv kev tiv thaiv kev ua haujlwm.
Ntxiv dag zog rau cov cua sov dissipation tsim ntawm lub zog hloov kho
Thaum lub sijhawm ua tus txheej txheem tiv thaiv overcurrent, ddayes tsim ib qho nyiaj ntawm cov cua sov. Txhawm rau txo nws qhov kev ua haujlwm kub thiab txhim kho kev ntseeg tau, nws yog qhov tsim nyog los txhawb qhov cua sov dissipation tsim ntawm lub zog adapter. Piv txwv li, tshav kub dissipation xws li tshav kub kub thiab kiv cua tuaj yeem siv tau los txo qhov kev ua haujlwm kub ntawm dodes.
