Tshiab Zog Siab-Voltage Circuit Protection: Technological Innovation rau Ceramic Tube rau EV BS Series

Raws li kev lag luam photovoltaic cov saw hlau hloov mus rau qhov ua tau zoo dua thiab cov nplai loj dua, daim ntawv thov scenarios rau fuses tau dhau los ua ntau haiv neeg. Rau cov hlua inverters hauv cov chaw nres tsheb fais fab photovoltaic, fuses nrog qis tam sim no feem ntau ua haujlwm; conversely, centralized systems nyob rau hauv loj -scale av- mounted fais fab chaw nres tsheb yuav tsum siab - fais fab khoom muaj peev xwm tuav tam sim no ntawm 80A los yog ntau dua. Cov qauv no tau tsav qhov txuas ntxiv ntawm cov thev naus laus zis hauv lub cev rau EV fuses, xav kom cov khoom siv no muaj lub zog zoo tshaj plaws thiab thermal shock resistance thaum tib lub sijhawm tuav lub teeb yuag profile. Nyob rau hauv cov nqe lus ntawm kev xaiv cov khoom, 95% alumina ceramic tau tshwm sim raws li cov khoom nyiam rau lub cev ntawm hluav taws xob tsheb auxiliary fuses, ua tsaug rau nws tshwj xeeb hluav taws xob rwb thaiv tsev zog, siab hardness, thiab siab - kub tsis kam; Cov khoom siv no ua rau muaj kev ntseeg siab ua haujlwm thoob plaws qhov kub ntawm -40℃txog 85 degree.

Hauv kev lag luam tsheb hluav taws xob, kev siv dav dav ntawm 800V siab -voltage platforms tau tsim cov kev cai nruj dua ntawm fuses. Onboard fuses yuav tsum tsis yog tsuas yog muaj peev xwm cuam tshuam luv luv - cov tam sim no ncav cuag ntau txhiab amperes nyob rau hauv lub sij hawm luv luv tab sis kuj tiv taus qhov kev vibrations hnyav thiab cov neeg kho tshuab shocks thaum lub tsheb khiav haujlwm. Yog li ntawd, kev tsim thiab kev tsim khoom ntawm ceramic lub cev rau EV fuses xav tau qhov tseeb heev. Cov khoom siv ceramic no rau DC automotive fuses feem ntau yog tsim los siv siab -purity steatite lossis alumina ceramics; los ntawm kev tshaj tawm isostatic nias thiab siab -kub sintering txheej txheem, niaj hnub phab ntsa tuab thiab tsis muaj micro- tawg yog ua kom ntseeg tau, yog li lav cov qauv kev ncaj ncees txawm nyob rau hauv luv luv - Circuit Court txhaum tej yam kev mob.

Txhawm rau kom haum rau ntau yam siab -voltage circuits nyob rau hauv lub tsheb fais fab, cov qauv ntawm insulating hluav taws xob steatite ceramic fuse lub cev muaj ntau ntau haiv neeg. Piv txwv li, nyob rau hauv lub ntsiab Circuit Court tiv thaiv ntawm cov roj teeb pob, ntsia liaj qhov rooj - txuas siab -voltage fuses yog feem ntau siv, yuav tsum tau hais tias cov alumina ceramic Cheebtsam rau cov bolted -kev twb kev txuas EV fuses muaj exceptionally siab flexural zog thiab sealing muaj peev xwm. Hloov pauv, hauv cov khoom siv hluav taws xob lossis On-Board Chargers (OBCs), lub hom phiaj rau lub cev ceramic hauv lub tsheb hluav taws xob pabcuam fuses hloov mus rau kev sib xyaw ua ke ntawm miniaturization thiab kev ntseeg siab, kom ntseeg tau meej tshaj thiab luv luv- tiv thaiv Circuit Court nyob rau hauv compact spatial txwv.

Dhau li ntawm lub tsheb fais fab nkaus xwb, hybrid electric tsheb (HEVs) kuj vam khom ntau ntawm kev tiv thaiv los ntawm siab -kev ua tau zoo fuses. Ceramic Cheebtsam tsim rau hluav taws xob thiab hybrid tsheb fuses yuav tsum muaj kev ruaj ntseg hluav taws xob ua haujlwm nyob rau hauv ib puag ncig nyuaj electromagnetic thiab nquag tsub nqi - tawm mus. High- zoo ceramic casings rau fuse txuas tau zoo cais qhov siab - kub hlau vapors generated thaum lub fuse nyob rau hauv lub caij melts, tiv thaiv lwm yam kab mob los yog luv luv Circuit Court nyob rau hauv sab nraud circuitry thiab tiv thaiv qhov siab -voltage kev nyab xeeb ntawm lub zog tshiab tsheb.

Hauv kev tsim kho vaj tse xws li DC charging chaw nres tsheb, kev ntseeg siab ntawm fuse txuas ncaj qha mus rau kev them nyiaj nyab xeeb. Ceramic tubes rau EV charger fuse txuas feem ntau xav tau tshwj xeeb huab cua tiv thaiv thiab tiv thaiv - cov khoom laus kom tiv taus qhov nyuaj thiab hloov pauv huab cua sab nraum zoov. Thaum lub sij hawm tsim cov txheej txheem, cov raj ceramic no tau kuaj xyuas cov thermal shock thiab airtightness soj ntsuam kom paub tseeb tias tsis muaj kev puas tsuaj los yog cua xau tshwm sim thaum lub sijhawm ua haujlwm ntev -, yog li lav qhov kev nyab xeeb ntawm cov txheej txheem them nyiaj.

Yuav kom ua tau raws li cov txheej txheem sib txawv ntawm ntau lub teb chaws thiab cheeb tsam, kev tsim cov raj ceramic rau siab -voltage fuses yuav tsum tau kho kom haum. Piv txwv li, fuse txuas ua raws li British Standard (BS) system yog raug rau cov kev qhia tshwj xeeb hais txog lawv qhov ntev thiab cov qauv. Kev tsim cov raj ceramic rau EV British Standard fuses thiab EV BS series xav kom cov tuam txhab tsim khoom muaj qhov siab tshaj plaws hauv kev tsim pwm thiab kev tswj cov txheej txheem, kom ntseeg tau tias cov khoom sib txuas seamlessly rau ntau yam siab -voltage power distribution systems raws li British Standards.

Hauv kev lag luam thiab qis -voltage fais fab faib sectors, ceramic raj rau EV DC fuses kuj ua lub luag haujlwm tseem ceeb. Cov khoom xws li ceramic lub cev rau Siemens LV HRC fuses - txawv los ntawm lawv cov qauv qhov ntev thiab cov khoom siv hluav taws xob zoo tshaj plaws - tau siv dav hauv ntau qhov chaw tswj kev lag luam thiab cov khoom siv hluav taws xob. Cov casings no pab tsis tau tsuas yog raws li lub cev teeb meem tab sis kuj ua hauj lwm raws li cov phab ntsa ntawm lub arc - tua chamber thaum lub fuse ua hauj lwm; ua hauj lwm ua ke nrog rau sab hauv arc - tua nruab nrab, lawv sai sai elongate thiab txias cov hluav taws xob arc, yog li ua kom muaj kev nyab xeeb cuam tshuam ntawm kev txhaum tam sim no.
