Dissmann Fais Fab Hluav Taws Xob (EV) fuses rau kev tsim kho lub tsheb 500 V dc thiab 1000 V dc suav nrog fuse kev ntsuas mus txog 1000 A. Cov hluav taws xob ntau dua thiab cov ntaus nqi tam sim no muaj li kev daws teeb meem.
Fuses rau them (on-board charger, DC / DC them) thiab lub zog tiv thaiv (roj teeb, inverter) muaj li 20, 25 thiab 30 hli txoj kab uas hla thiab mus txog square lub cev qhov ntau thiab tsawg 1 thiab 2.
10 hli ferrule, ntsia liaj qhov rooj lossis PCB lub davhlau ya nyob twg rau lub tshuab pabcuam (DC / DC inverter, rhaub,…) ua kom tiav cov kev ua haujlwm rau fused EV tiv thaiv.
Tsheb Fais Fab thiab Kev Tiv Thaiv Them
Cov khoom siv fuse rau EV / HEV daim ntawv thov yog qhov tshiab hauv kev lag luam, lawv tuaj yeem raug suav tias yog qhov khoom hla ntawm qhov hluav taws xob tsawg fuse thiab fuse tsheb.
Raws li tam sim no tsis muaj cov qauv kev lees paub lossis cov qauv kev lag luam tau hais tseg.
EV Qhia Kev Xaiv Taw Qhia
Cov khoom siv fuse rau EV / HEV daim ntawv thov yog qhov tshiab hauv kev lag luam, lawv tuaj yeem raug suav tias yog qhov khoom hla ntawm qhov hluav taws xob tsawg fuse thiab fuse tsheb.
Raws li tam sim no tsis muaj cov qauv kev lees paub lossis cov qauv kev lag luam tau hais tseg.
Cov kauj ruam hauv qab no yuav pab koj xaiv qhov kom raug EV fuse rau kev siv tsheb:
Rated Voltage Vn: Qhov ntsuas qhov ntsuas ntawm qhov fuse yuav tsum tsis qis tshaj qhov ua haujlwm voltage ntawm lub system. Rau cov laj thawj EV thiab chaw nres tsheb ceev them DC fuses yuav tsum muaj ntaub ntawv thov.
Rated Tam Sim No Hauv: Suav los ntsuas qhov ntsuas ntaus nqi kom raug raws li qhov thauj khoom ntau tshaj plaws tam sim no ntawm lub system. Nqa kuj rau tsheb daim ntawv thov kev nyob rau hauv kev txiav txim siab.
Qhov ntau thiab tsawg: Nrhiav kom haum qhov ntev thiab mounting txoj kev rau daim ntawv thov. Automotive qib fuses yuav tsum ua kom ruaj khov, feem ntau ntsia liaj qhov rooj ntsia.
Kev xaim, muaj peev xwm ntau dhau: txiav txim siab, yog tias yuav tsum muaj kev tiv thaiv cable ntxiv. Nws raug nquahu tias txoj haujlwm pabcuam tiv thaiv kom phim rau kev tiv thaiv cable kom deb li deb tau.
Cov txheej txheem rau qhov tam sim no ntawm cov fuse raws li Ib: Ib=Hauv x KT x Ke x Kv x Kf
Hloov pauv mus rau: In≥ Ib / (KT x Ke x Kv x Kf)
Hauv: nyob tam sim no ntawm fuse
Ib qho: qhov tso cai siab tshaj plaws nruam thauj khoom tam sim no hauv Circuit Court, txiav txim siab los ntawm kev ua haujlwm tam sim no ntawm daim ntawv thov
KT: ntsuas kub derating yam, txiav txim siab los ntawm ntsuas qhov ntsuas kub ntawm lub ntsuas kub
Ke: Thaum tshav kub kub hloov chaw ntawm lub tshuab txuas nrog
Lub fuse feem ntau txuas nrog los ntawm tooj liab tooj. Thaum tshav kub kub hloov tuaj yeem txiav txim siab raws li qhov tam sim no ntom ntom hauv qhov sib txuas ntawm tooj liab ntsia hlau loj hauv tus neeg ua yeeb yam kho kev nkhaus ntawm kev sib txuas ntawm cov khoom siv hloov cua sov.
Feem ntau, fuse tooj liab bar muaj qhov ntom ntom tam sim no ntawm 1 - 1.6 amp / mm², yog tias cov ntsuas ntsuas siab siab, sim kho qhov ceev tam sim no mus rau tus nqi qis dua.
Raws li qhov ua tiav nrog Kt, dag txias yuav cuam tshuam rau lub sijhawm ua haujlwm ntawm lub fuse ib yam nkaus. Kev tso cua txias yog qhov pom zoo tshaj plaws rau daim ntawv thov EV, nyob rau hauv qhov ntawd peb muaj ib qho ua tau ntawm Kv=1.
Kf: Qhov ntau zaus hloov kho tau
Hauv qab 1000 Hz zaus ntawm DC qhov tam sim no, Kf tus nqi yog 1
Raws li cov hloov pauv los ntawm kev xaiv ua ntej, thiab coj mus rau hauv kev ntsuas qhov ntsuas qhov ntsuas ntawm 1.6 rau hluav taws xob tsheb, tam sim no peb tuaj yeem suav qhov ntsuas fuse kom zoo:
In≥ 1.6 x [Ib / (KT x Ke x Kv x Kf)]

Them taw tes rau sau lub cev muaj zog them xwb tam sim no
DC / DC Inverter thiab lub roj teeb hloov mus hloov chaw uas yuav siv mus rau kev khaws cia
