Hauv peb lub tebchaws, cov khoom siv hluav taws xob sib txuas lus feem ntau siv -48V fais fab mov. Raws li tus kws tshaj lij, koj puas paub vim li cas?
Ua ntej yuav daws cov lus nug no, cia peb nkag siab qhov twg -48V fais fab mov los ntawm!
█ -48V fais fab tuag li cas?
Lub zog hluav taws xob rau cov khoom siv sib txuas lus tuaj yeem yog AC lub zog lossis DC lub zog.
Txhawm rau ua tiav cov khoom siv hluav taws xob tsis cuam tshuam, ntxiv rau UPS (Uninterruptible Power Supply, uninterruptible power supply), peb yuav tsum tso siab rau lub hwj chim khaws cia hauv cov roj teeb. Tus saib xyuas module yog lub luag haujlwm rau kev tswj hwm tag nrho cov kab ke thiab xa cov ntaub ntawv mus rau lub chaw soj ntsuam tej thaj chaw deb.
Daim duab hauv qab no siv lub zog hluav taws xob ua piv txwv los qhia txog cov qauv kev ua haujlwm ntawm kev sib txuas lus fais fab mov.
Raws li tau pom los ntawm daim duab saum toj no,lub -48V fais fab mov yog hloov los ntawm alternating tam sim no los yog high-voltage ncaj tam sim no los ntawm ib tug rectifier module .
█ Vim li cas thiaj siv -48V fais fab mov?
Pom qhov no, ntau tus neeg yuav nug:
Yog vim li cas lub hwj chim mov voltage -48V?
Vim li cas nws yog -48V, tsis yog +48V?
Qhov txawv ntawm -48V thiab +48V yog dab tsi?

Yog vim li cas lub hwj chim mov voltage -48V?
Vim li cas qhov hluav taws xob sib txuas lus siv -48V voltage? Qhov tseeb, qhov laj thawj feem ntau yog los ntawm cov hauv qab no:
1 Yog vim li cas keeb kwm :
Feem ntau ntawm cov khoom siv sib txuas lus ntxov tshaj plaws uas siv hauv keeb kwm, xws li xov tooj, tau siv los ntawm -48 V voltage, thiab cov khoom siv hluav taws xob sib txuas lus tau muab los ntawm lub chaw saib xyuas kev sib txuas lus.
2 yam kev nyab xeeb :
Thoob ntiaj teb, qhov hluav taws xob DC ntawm -36V txhais tau tias yog qhov muaj kev nyab xeeb. -48V yog me ntsis siab dua qhov kev nyab xeeb voltage, thiab qhov hluav taws xob poob ntawm kab yuav me dua. Nyob rau hauv cov xwm txheej muaj kev nyab xeeb, kev sib txuas lus ntev ntev rau kev hu xov tooj hauv zos tau raug lees paub.
Nrog rau kev txhim kho txuas ntxiv thiab kev nce qib ntawm cov ntaub ntawv thev naus laus zis, txhawm rau ua kom tau raws li cov cuab yeej siv thaum ntxov thiab txo cov nqi, -48V fais fab mov tau siv txog tam sim no.
3 Txo qhov poob :
Nws yog qhov tsim nyog rau kev xa hluav taws xob thiab tuaj yeem txo qhov poob ntawm cov khoom siv hluav taws xob.
High voltage yog qhov txaus ntshai rau kev siv ntau dua li qhov hluav taws xob tsawg. Rau qhov tsis tshua muaj hluav taws xob kis tau tus mob, vim tias tam sim no ntawm cov kab hluav taws xob ntawm tib lub zog loj dhau lawm, cov kab hluav taws xob yuav tsum tau txo qis, yog li cov kab hluav taws xob tuab yuav tsum raug xaiv, uas yuav ua rau cov nqi nce ntxiv thiab tseem tuaj yeem cuam tshuam rau kev ua haujlwm ib txwm muaj. kev sib txuas lus system.
QHOV TSEEB. 0 2
Vim li cas -48V tsis yog +48V?
Kev siv ntawm -48V yog feem ntau vim yog cov yam ntxwv ntawm electrochemical ntawm kis kab mob nruab nrab ntawm cov khoom siv sib txuas lus. Lub polarity ntawm -48V yog qhov tsis zoo, uas yog, qhov zoo electrode yog grounded.
Qhov no yog vimkhoom siv sib txuas lussiv DC fais fab mov, thiab muaj cov av noo nyob rau hauv cov huab cua, uas ua rau lub zoo electrode ntawm cov khoom yuav tsum tau electrolytically corroded los ntawm cov electrolysis ntawm DC zog.
Grounding qhov zoo electrodentawm cov khoom siv fais fabtuaj yeem nqus tau cov nqi tsis zoo hauv huab cua, txo qhov corrosion ntawm qhov zoo electrode ntawm cov khoom siv hluav taws xob, thiab yog li tiv thaiv cov txheej txheem ntawm cov khoom siv hluav taws xob los ntawm xeb.
QHOV TSEEB. 0 3
Qhov txawv ntawm -48V thiab +48V yog dab tsi?
Qhov voltages ntawm -48V thiab +48V yog sib npaug,qhov sib txawv nyob rau hauv cov kev taw qhia ntawm tam sim no .
Cov hluav taws xob tsis zoo yog siv vim tias cov hluav taws xob tsis zoo thiab yuav ntws mus rau qhov zoo ntawm qhov hluav taws xob, yog li tiv thaiv ntau cov hluav taws xob los ntawm kev sib sau ua ke ntawm cov khoom siv sib txuas lus, yog li txo qhov tsis ua hauj lwm ntawm cov khoom siv sib txuas lus.
Nthuav cov ntsiab lus txuas ntxiv
-48V Koj puas nkag siab? ! Yog li dab tsi yog -53.5V?
53.5V yog tus nqi hluav taws xob ntab. Hauv cov khoom siv hluav taws xob niaj hnub, cov khoom siv hluav taws xob yuav tsum ntab them lub roj teeb, yog li qhov ntsuas ntsuas qhov tseeb yog -53.5V.
█ Cov lus qhia ntxiv
Txawm hais tias Tuam Tshoj txoj kev sib txuas lus siv hluav taws xob siv -48V fais fab mov,tsis yog txhua lub tebchaws siv -48V fais fab mov system. Piv txwv li, Russia yuav siv lub tshuab hluav taws xob -60V, thiab qee lub tebchaws siv -24V fais fab mov system.
Yog li ntawd, yog tias cov khoom yuav tsum tau nce mus rau lwm qhov chaw nrog cov khoom siv hluav taws xob sib txawv, cov qauv kev sib txuas lus hluav taws xob ntawm cov cheeb tsam no yuav tsum tau muab coj los xav.
