Fuses rau cov ntawv thov hauv Cov Tsheb Hluav Taws Xob (EV) lossis Hybrid EV kuj yog qhov tshiab hauv kev lag luam.
Lub tsheb hluav taws xob kev lag luam txuas ntxiv mus. Cov neeg kho tsheb tau cog lus ruaj khov los hloov lawv cov khoom tsim rau tsav hluav taws xob, thiab tsoomfwv hauv lub tebchaws tau tsim cov phiaj xwm mus rau theem sab hauv cov tsheb sib txuas kom tau raws li lawv cov huab cua thiab huab cua ua tiav. Cov tsheb thauj hluav taws xob txhais tau tam sim no yog kev ua lag luam loj; kev nyab xeeb thiab kev ntseeg tau yog qhov tseem ceeb tshaj rau lub tsheb thiab lawv cov neeg nyob. Thiab txhua qhov chaw muaj cov khoom siv hluav taws xob, cov khoom siv hluav taws xob xws li lub roj teeb, DC contactor, chav faib hluav taws xob, lossis ntu txuas hluav taws xob yuav tsum muaj kev tiv thaiv los ntawm Over Current Protection Devices (OCPD), lossis - fuses.
Fuses rau cov ntawv thov hauv Cov Tsheb Hluav Taws Xob (EV) lossis Hybrid EV yog qhov tshiab hauv kev lag luam thiab lawv tuaj yeem raug suav tias yog qhov khoom hla ntawm qhov hluav taws xob tsawg fuse thiab fuse tsheb. Qhov xav tau ntawm kev tiv thaiv ntawm lub zog hluav taws xob nyob hauv lub ntiaj teb tsheb ua raws li DC lub roj teeb hluav taws xob tau nthuav tawm tag nrho cov kev cov nyom tshiab. Fuses thov rau DC roj teeb kev siv hauv EV yuav tsum tau lees tias muaj kev tiv thaiv nrawm rau qhov muaj ntau qhov txhaum hloov siab; withstand ib theem ntawm kev them thiab rho tawm mus, kev ceev, kev tsim dua tshiab braking; tag nrho cov sijhawm raug rau cov xwm txheej ib puag ncig zoo xws li kev tshee, thiab cov kev hloov pauv dav hauv cov khoom kub ib puag ncig. Txawm hais tias txhua lub tsheb' s txoj kab ke ua haujlwm tsis zoo sib xws; txheej txheej txheem tuaj yeem siv rau kev xaiv fuse ua kom muaj kev tiv thaiv zoo thiab kev ntseeg tau ntev ntev.
Kev ntsuas tus nqi fuse tam sim no nyob ntawm hom kev ntsuam xyuas tshwj xeeb tau teev tseg los ntawm cov qauv thiab ua hauv qhov ntsuas ntsuas pom Txawm li cas los xij nyob rau hauv cov ntawv thov tiag tiag, cov haujlwm ua haujlwm hauv cov khoom siv uas fuses tau nruab yog tsis tshua zoo tib yam li cov kev mob uas siv thaum hom kev sim. Fuses yog cov khoom siv thermal: txhua yam uas hloov pauv hloov lawv cov cua sov hloov pauv mus txuas ntxiv tam sim no nqa lub peev xwm.
Cov fuses niaj hnub ua nyob rau hauv ntau cov duab thiab ntau qhov loj txawm li cas los xij muaj cov yam ntxwv tseem ceeb rau txhua qhov fuses Qhov tseem ceeb ntawm cov fuse yog qhov txiav tawm-choj. Nws yuav tsum tau ua los ntawm cov khoom siv khoom ntau ntawm siab thiab zoo li tus qauv los ua ntau cov ntu ntu txo ua 'caj dab' lossis 'tsis muaj zog'. Nws yog tsuas yog cov tshooj txo uas yuav tswj cov kev ua haujlwm ntawm lub fuse. Lub ntsiab yog ib puag ncig nrog cov khoom siv arc quenching, feem ntau muab qhab nia quartz, uas quenches arc tsim thaum cov ntu txo. Nws yog txoj haujlwm no uas muab lub fuse nws qhov peev xwm tam sim no. Lub quartz yog muaj nyob hauv ib lub taub ntim insulating feem ntau ntawm ceramic lossis engineering yas feem ntau hu ua fuse lub cev. Thaum kawg, txhawm rau txuas lub fuse caij mus rau hauv Circuit Court muaj qhov kawg txuas, feem ntau ntawm tooj liab. Lwm feem ntu ntawm kev siv fuse sib txawv raws li hom ntawm fuse thiab kev tsim khoom siv
