Raws li tus neeg saib xyuas kev tiv thaiv kev ua haujlwm ruaj khov ntawm lub tsheb hluav taws xob, lub fuse ua lub luag haujlwm tseem ceeb hauv lub voj voog. Txuas nyob rau hauv series, nws siv cov thermal teebmeem uas tsim los ntawm overcurrents thaum lub sij hawm luv luv circuits los yog overloads kom yaj thiab vaporize nws sab hauv, yog li tsim ib tug qhib Circuit Court thiab cuam tshuam txoj kev faulty los ntawm extinguishing lub resulting hluav taws xob arc. Nrog cov tsheb tshiab lub zog tag nrho nkag mus rau lub sijhawm ntawm siab -voltage platforms- ua haujlwm ntawm 800V thiab txawm siab dua - ib txwm qis-voltage fuses tsis txaus los ua kom tau raws li qhov xav tau tam sim no. Yog li ntawd, siab -voltage fais fab fuses- feem ntau ua haujlwm nyob rau hauv thaj tsam ntawm 60 VDC txog 1500 VDC- tau tshwm sim los ua qhov tseem ceeb tshaj plaws rau ob qho tib si lub ntsiab thiab cov khoom siv hluav taws xob. Nyob rau hauv qhov kev thov ib puag ncig no, siab -kev ua tau zoo EV fuse ceramic lub cev tau dhau los ua qhov nruab nrab nyiam rau encapsulating lub fuse caij thiab cais cov hluav taws xob arcs, ua tsaug rau lawv cov khoom tshwj xeeb rwb thaiv tsev, siab -kub tsis kam, thiab thermal shock resilience.
Automotive fuses feem ntau muab faib ua ob pawg loj: qis-voltage thiab siab-voltage. Ntawm cov no, cov qauv tsim thiab kev xaiv cov khoom siv siab -voltage fuses ncaj qha txiav txim siab tag nrho cov hluav taws xob kev nyab xeeb ntawm lub tsheb. Lawv cov khoom tseem ceeb feem ntau suav nrog lub fuse tube, lub fuse caij, lub fuse tuav, thiab lub fuse cap. Tshwj xeeb tshaj yog, lub fuse tube ua haujlwm tseem ceeb hauv tsev rau lub arc - tua nruab nrab thiab lub fuse caij; nws feem ntau yog tsim los ua ib tug hollow cylindrical qauv ua los ntawm tshwj xeeb ceramics. Lub ntsiab lus fuse-feem ntau yog tsim los ntawm cov hlau lead-antimony lossis silver alloys- yog lub luag haujlwm rau kev hnov cov dej ntws tam sim no thiab rupturing nyob rau hauv qhov xwm txheej ntawm qhov tsis xws luag. Lub caij no, lub fuse tuav thiab lub hau muab kev ruaj ntseg txhua yam mounting thiab kev tiv thaiv sab nraud. Nyob rau hauv thaj chaw ntawm kev lag luam thiab cov khoom siv hluav taws xob hauv tsheb, cov khoom siv hluav taws xob classic tsim rau Siemens LV HRC fuses muaj kev tiv thaiv paub tab thiab txhim khu kev qha rau ntau qhov sib txawv ntawm cov khoom siv hluav taws xob, qhov txawv ntawm nws qhov ntev thiab cov yam ntxwv ntawm lub cev ruaj khov.
Hais txog cov kev ua haujlwm nyuaj tshwj xeeb rau lub zog tshiab, kev tsim tshwj xeeb "Ceramic Lub Cev rau EV Fuses" yuav tsum suav nrog tsis yog cov qauv hluav taws xob nkaus xwb tab sis kuj tseem muaj kev vibrations hnyav thiab qhov kub thiab txias sib txawv thaum lub sijhawm ua haujlwm hauv tsheb. High-cov khoom siv ceramic zoo kom ntseeg tau tias sab hauv arc-quenching media-xws li quartz xuab zeb- tsis txhob xau lossis degrade nyob rau hauv ib puag ncig huab cua. Qhov no tau lees tias, txawm tias thaum cuam tshuam luv luv - Circuit Court tam sim no mus txog kaum tawm txhiab tus amperes, lub fuse tuaj yeem tua cov arc sai sai, yog li tiv thaiv kev puas tsuaj rau cov pob roj teeb lossis cov tshuab hluav taws xob. Qhov kev tshawb nrhiav tsis tu ncua ntawm cov khoom siv hnyav ua haujlwm ua lub hauv paus ntawm siab -voltage kev nyab xeeb tsim hauv cov tsheb fais fab niaj hnub.
Tshaj li lub hauv paus tseem ceeb ntawm lub tsev tsav lub cev muaj zog, cov khoom siv pab cuam -xws li lub tsheb lub tshuab cua txias compressor thiab PTC cua sov- kuj xav tau kev tiv thaiv overcurrent. "Ceramic Lub Cev rau Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob" feem ntau yog qhov loj dua me me tab sis muaj qhov tshwj xeeb siab rwb thaiv tsev tiv thaiv thiab lub zog txhua yam. Lawv raug tsim los ua kom haum rau qhov ntsuas tam sim no ntawm cov cuab yeej pabcuam, ua kom nrawm nrawm thaum muaj kev tshaj tawm lossis luv luv. Qhov no ua tau zoo tiv thaiv ib qho kev pabcuam tsis ua haujlwm los ntawm kev ua rau lub tsheb tag nrho siab -voltage system, yog li ua kom muaj txiaj ntsig zoo rau cov neeg siv kev paub thiab kev nyab xeeb tag nrho ntawm lub tsheb.
Hauv paus, tsis hais txog ntawm qhov tshwj xeeb Circuit Court uas nws tau siv, tus nqi tseem ceeb ntawm lub fuse yog nyob rau hauv kev muab ib qho instantaneous thiab txhim khu kev qha lub cev disconnection mechanism. "Ceramic Lub Cev rau Kev Tshaj Tawm thiab Kev Tiv Thaiv luv luv luv" yuav tsum muaj cov thermal conductivity zoo heev kom tshem tawm cov cua sov uas tsim tawm thaum lub sijhawm ua haujlwm ib txwm muaj, thaum tib lub sijhawm tiv taus qhov siab - kub thiab siab -siab shockwaves tsim los ntawm vaporization ntawm lub fuse caij nyob rau hauv milliseconds ntawm qhov ua txhaum tshwm sim. Cov tshuaj lom neeg ruaj khov ntawm cov ntaub ntawv ceramic kom ntseeg tau tias lawv tsis muaj hnub nyoog lossis deform dua lawv lub neej ua haujlwm ntev, yog li lav qhov kev ncaj ncees ntawm lawv cov yam ntxwv tiv thaiv.
Nyob rau hauv siab -voltage DC systems, tsis muaj lub ntuj tam sim no xoom- hla cov ntsiab lus pom hauv AC circuits ua rau arc extinction exponentially nyuaj dua. Yog li ntawd, cov khoom tsim tshwj xeeb tsim rau "Ceramics rau DC Automotive Fuses" yog qhov tseem ceeb. Cov ceramics feem ntau muaj qhov tshwj xeeb siab purity thiab ntom, ua rau lawv ua kom muaj zog arc. Thaum sib xyaw ua ke nrog cov qauv tsim fuse tsim, lawv ua tiav qhov cuam tshuam tsis zoo ntawm DC tam sim no, yog li tsim kom muaj kev nyab xeeb tsis zoo rau onboard DC-DC converters thiab High-Voltage Power Distribution Units (PDUs).
Ntawm cov array loj ntawm cov ntaub ntawv ceramic, steatite ceramic yog dav siv vim nws qhov tshwj xeeb siab - zaus rwb thaiv tsev zog thiab thermal shock resistance. Lub insulating hluav taws xob steatite ceramic fused lub cev tsis tsuas yog nthuav tawm cov machinability zoo heev -ua rau kev tsim ntau yam, kev cai- cov qauv zoo li tus- tab sis kuj tseem muaj cov nqi tsim khoom lag luam. Hauv cov ntawv thov uas suav nrog tus nqi-rhiab tsis tau siab heev- qhov yuav tsum tau muaj kev ntseeg siab- xws li hauv qee qhov nruab nrab - mus rau - qis- cov qauv tsheb kawg lossis rau kev tiv thaiv cov khoom tshwj xeeb- steatite ceramic fuse vaj tse tseem yog tus nqi siab heev - siv tau zoo engineering
Nyob rau hauv ib lub fuse, qhov kev sib tshuam ntawm cov khoom siv fuse sab hauv thiab lub davhlau ya nyob twg cov hlau lead - tawm feem ntau xav tau cov khoom siv ceramic ntawm qhov siab tshaj plaws los xyuas kom muaj kev kho kom zoo thiab hluav taws xob rwb thaiv tsev. Ceramic casing rau lub fuse txuas ncaj qha los yog txhawb nqa cov khoom siv hlau fuse zoo; kev khiav hauj lwm nyob rau hauv ib tug confined qhov chaw, nws yuav tsum muab kiag li hluav taws xob cais los tiv thaiv nto creepage los yog dielectric puas. Qhov tseeb qhov tseeb thiab qhov chaw tiav ntawm cov tsho me me ceramic no ncaj qha cuam tshuam qhov tseeb ntawm lub sijhawm fuse -tam sim no tus yam ntxwv nkhaus.
Raws li kev tswj hwm ib puag ncig thoob ntiaj teb tau dhau los ua nruj zuj zus thiab cov neeg siv khoom ntxhov siab txog kev tsav tsheb ntau zuj zus, lub zog tshiab tsheb tau hloov mus rau kev ua haujlwm zoo dua thiab sib dua. Kev loj hlob ntawm ceramics rauhluav taws xob thiab hybrid tsheb fusestseem tab tom ua iteration tsis tu ncua; Thaum khaws lawv cov txiaj ntsig zoo hauv kev rwb thaiv tsev thiab qhov hluav taws xob tiv taus lub peev xwm, cov ntaub ntawv tshiab cov khoom siv ceramic tau txo qis lawv tus kheej qhov hnyav thiab thermal muaj peev xwm. Qhov no ua rau muaj kev txhim kho tag nrho lub zog ceev ntawm lub tsheb, zoo kawg nkaus ua tau raws li qhov yuav tsum tau muaj rau cov khoom hauv ob qho tib si ntshiab hluav taws xob thiab hybrid qauv.
