Hauv peb cov ntawv tshaj tawm dhau los, peb muab cov neeg nyeem nrog cov lus qhia yooj yim rau cov hnub ci vaj huam sib luag hauv tsev.Ntawm no peb yuav txuas ntxiv lub ntsiab lus no los ntawm kev muab koj cov lus qhia cais rau hnub ci cables.
Hnub ci cables, raws li lub npe qhia, yog cov khoom siv rau kev xa hluav taws xob.Yog tias koj yog tus tshiab rau PV systems, nws yog ib qho tseem ceeb kom kawm paub cov hauv paus.
Nyeem rau kom paub ntau ntxiv txog hom kab no, suav nrog lawv ua haujlwm li cas, lawv siv rau dab tsi, thiab xaiv cov kab hluav taws xob zoo li cas.
Hnub ci cable hauv photovoltaic system
Tsuav muaj hluav taws xob, yuav tsum muaj cov xov hlau thiab cables.Photovoltaic systems tsis muaj kev zam.
Cov hlau thiab cables ua lub luag haujlwm tseem ceeb hauv kev tau txais kev ua tau zoo tshaj plaws los ntawm cov tshuab hluav taws xob.Nyob rau hauv cov ntaub ntawv ntawm photovoltaic systems, qhov kev xav tau rau cov zoo hnub ci xov hlau thiab cables ua ib qho tseem ceeb heev.
Cov tshuab photovoltaic muaj ib lossis ntau lub hnub ci vaj huam sib luag ua ke nrog inverters thiab lwm yam khoom siv.Nws siv lub hnub ci zog los tsim hluav taws xob.
Txhawm rau kom tau txais txiaj ntsig zoo tshaj plaws ntawm lub hnub, lub tshuab hluav taws xob photovoltaic lossis lub hnub ci vaj huam sib luag yuav tsum ua haujlwm "kho" thiab nyob rau hauv kev txiav txim.Ib qho ntawm cov khoom tseem ceeb yog lub hnub ci cable.
Lawv yog dab tsi?
Hnub ci cables yog tsim los xa DC hnub ci zog los ntawm photovoltaic systems.Lawv yog siv los ua kev sib txuas cables rau hnub ci vaj huam sib luag thiab photovoltaic arrays hauv daim phiaj hnub ci.
Lawv muaj lub zog mechanical siab thiab tuaj yeem tiv taus huab cua hnyav.Hauv cov phiaj xwm hnub ci, cov hnub ci hluav taws xob feem ntau muab tso rau sab nraud thiab raug rau qhov kub thiab txias.
Thaum lawv lub neej ntev li ntawm 20 txog 25 xyoos, lawv tuaj yeem ntsib qhov chaw hnyav.Yog li ntawd, nws yog ib qho tseem ceeb rau nruab koj lub hnub ci nrog lub hnub ci zoo thiab cov cables.
Hnub ci cables raug cais raws li tus naj npawb ntawm cov xov hlau thiab lawv cov specifications.Tsis tas li ntawd, txoj kab uas hla kuj nyob ntawm cov xov hlau thiab lawv cov specifications.
Feem ntau hais lus, muaj peb hom hnub ci cables siv nyob rau hauv photovoltaic systems:
Dc hnub ci cable
Hnub ci DC lub ntsiab cable
Hnub ci ac cable
Hom hnub ci cable
Hauv cov phiaj xwm hnub ci fais fab, ntau hom cables yuav tsum tau ua kom tiav txoj haujlwm.Ob lub DC thiab AC cables tuaj yeem siv tau.
Lub vaj huam sib luag photovoltaic thiab lub inverter, nrog rau lub thawv sib txuas, txuas nrog DC cable.Nyob rau tib lub sijhawm, lub inverter thiab sub-chaw nres tsheb txuas nrog AC cable.
1. Dc hnub ci cable
Dc hnub ci cables yog ib leeg-core tooj liab cables nrog rwb thaiv tsev thiab sheathed.Lawv siv nyob rau hauv photovoltaic hnub ci vaj huam sib luag thiab tuaj yeem ua modules lossis hlua cables.
Tsis tas li ntawd, lawv tuaj nrog cov khoom sib txuas tsim nyog thiab ua ntej ua ntej rau hauv lub vaj huam sib luag.Yog li ntawd, koj yuav tsis muaj peev xwm hloov lawv.
Qee zaum, koj yuav xav tau ib txoj hlua ntawm DC hnub ci cable los txuas rau lwm lub vaj huam sib luag.
2. Main hnub ci DC cable
Lub ntsiab DC cable yog lub hwj huam loj loj sau cable.Lawv txuas lub generator junction box rau qhov zoo thiab tsis zoo cables ntawm lub hauv paus inverter.
Tsis tas li ntawd, lawv tuaj yeem yog ib leeg lossis ob chav tub ntxhais cables.Ib leeg tub ntxhais hlau nrog ob chav rwb thaiv tsev yog ib qho kev daws teeb meem los muab kev ntseeg siab.Nyob rau tib lub sijhawm, kev sib txuas ntawm lub hnub ci inverter thiab lub tshuab hluav taws xob sib txuas lub thawv, qhov zoo tshaj plaws siv dual-core DC cable.
Cov kws tshaj lij feem ntau nyiam kev teeb tsa sab nraum zoov ntawm DC hnub ci lub ntsiab cables.Qhov ntau thiab tsawg yog 2 hli, 4 hli thiab 6 hli.
Lus Cim: Kom tsis txhob muaj teeb meem xws li luv luv Circuit Court thiab hauv av, nws raug nquahu kom cov cables nrog cov polarity sib cais.
3. Ac kab
Ac cables txuas lub hnub ci inverter rau cov cuab yeej tiv thaiv thiab daim phiaj hluav taws xob.Rau me me PV systems nrog peb-theem inverters, ib tug tsib-core AC cable yog siv los txuas rau daim phiaj.
Kev faib tawm ntawm cov hlau yog raws li nram no:
Peb kab nyob,
Ib qho av xaim thiab ib txoj kab nruab nrab.
Tswv yim: Yog tias koj PV system muaj ib theem inverter, siv peb-core AC cable.
Qhov tseem ceeb ntawm hnub ci cable hauv PV tej yaam num
Raws li tau hais ua ntej lawm, hnub ci cables xa DC hnub ci zog los ntawm ib feem ntawm cov cuab yeej photovoltaic mus rau lwm qhov.Kev tswj cov kab hluav taws xob kom zoo yog qhov tseem ceeb thaum nws los txog rau kev nyab xeeb thiab kev ua haujlwm ntev ntawm txhua qhov PV system.
Lub installation ntawm cables nyob rau hauv lub hnub ci tej yaam num yog raug rau ultraviolet hluav taws xob, huab cua kub thiab av noo.Lawv tuaj yeem tiv taus qhov xav tau hnyav ntawm cov tshuab photovoltaic - ob sab hauv tsev thiab sab nraum zoov.
Tsis tas li ntawd, cov cables no tsis yog tsuas yog muaj zog, tab sis kuj tiv taus huab cua.Lawv tuaj yeem tiv taus kev ntxhov siab los ntawm kev siab, khoov lossis ncab, thiab tshuaj lom neeg kev ntxhov siab nyob rau hauv daim ntawv ntawm:
Xaiv txoj cai hnub ci cable rau koj PV system
Hnub ci cables yuav tsum tsim nyog rau cov kev xav tau tshaj plaws PV system daim ntawv thov.Xaiv tus qauv uas muaj kev tiv thaiv siab tshaj plaws rau cov teeb meem atmospheric xws li UV, ozone, thiab av noo.
Tsis tas li ntawd xwb, tab sis lub cable yuav tsum tuaj yeem tiv taus qhov kub thiab txias (-40 ° C txog 120 ° C).Muaj hnav, cuam tshuam, tearing thiab siab.
Ib kauj ruam ntxiv, txoj cai hnub ci
