Nyob rau hauv lub hnub ci photovoltaic (PV), xaiv cov xaim thiab cov xaim yog qhov tseem ceeb heev rau kev nyab xeeb, ua haujlwm, thiab ntev ruaj khov ntawm lub system. Nrog rau kev loj hlob sai ntawm cov photovoltaic kev lag luam, ntau thiab ntau lub tsev thiab cov lag luam yog xaiv los nruab hnub ci. Ib qho ntawm cov lus nug ib txwm muaj: tuaj yeem siv -2 cov kab ke tau siv raws li lub hnub ci cable? Txhawm rau teb cov lus nug no, peb yuav tsum muaj kev nkag siab tob txog cov yam ntxwv ntawm lub hnub ci thiab hnub ci, thiab cov ntawv thov ntawm ob qho tib si hauv photovoltaic.
Kab lus no yuav tham txog cov qauv thiab cov yam ntxwv ntawm lub hnub ci clesirs thiab solar xaim hauv kev siv ntawm lawv thiab mob siab lug pheeb suab cables.
1. Dab tsi yogHnub ci cablesThiab cov xov hlau xov hlau?
1.1 Hnub Ci Cable
Hnub ci clesles yog cables tsim tshwj xeeb rau photovoltaic. Lawv feem ntau tawm tsam UV Rays, Dej Kub, Dej, thiab Kev Laus, thiab tuaj yeem tiv taus cov xwm txheej hnyav hauv ib puag ncig sab nraum zoov ntev. Hnub ci cable feem ntau yog muaj cov neeg saib xyuas, rwb thaiv tsev cov khaubncaws sab nraud thiab txheej txheem sab nraud. Cov neeg saib xyuas feem ntau ua los ntawm tooj liab lossis txhuas, thiab cov ntaub ntawv rwb thaiv tsev feem ntau (xlpe), polyvinyl chloride (PVC) thiab lwm yam ntaub ntawv nrog cov khoom siv kub siab.
Cov chaw ua haujlwm tseem ceeb ntawm lub hnub ci cables yog txuas lub hnub ci rau inverters lossis lub zog cia tsim los ntawm photovoltaic models rau lub tshuab hluav taws xob.
1.2Hnub Ci Hlau
Cov xaim xaim yog hais txog ib tus xaim siv hauv photovoltaic, thiab feem ntau tseem ua lub luag haujlwm hauv lub hwj chim sib kis hauv photovoltaic. Qhov txawv tshaj plaws ntawm nws thiab lub hnub ci cables yog nws cov qauv. Cables yog tsim los ntawm ntau cov xov hlau bundled ua ke thiab sib qhia ib qho riam sab nraud, thaum xaim yog ib lub xov hlau ib leeg. Hnub ci cov xov hlau feem ntau siv nyob rau hauv luv-deb, saj zawg zog kev sib txuas nrog cov xwm txheej.
2. Lub ntsiab lus ntawm kev siv -2 tus qauv
Kev siv {{{0} Txheem yog tus qauv rau kev pabcuam hauv av (NEC), feem ntau yog siv rau sab nraum zoov lossis hauv qab hluav taws xob kis. Siv -2 cov cable yog tsim los txuas cov kab hluav taws xob thiab cov tsev, thiab feem ntau nqa cov roj ntsha thiab tsis muaj zog. Siv -2 cov kab ntsig yog tus cwj pwm los ntawm cov dej kub siab, thiab siv tshuaj lom neeg corrosion, tshwj xeeb tshaj yog nyob hauv thaj chaw uas raug cov chaw tshav ntuj thiab cov chaw hnyav.
Yuav tsum muaj kev ntsuas tshwj xeeb rau kev siv -2} cables muaj xws li:
Kev kub siab kuj:Muaj peev xwm ua haujlwm ruaj khov nyob hauv ib puag ncig kub.
UV Kuj:Muaj peev xwm tiv taus ntev ntev UV hluav taws xob thiab yuav tsis muaj hnub nyoog vim muaj kev kis tau.
Waterproof:Haum rau hauv av installation thiab tuaj yeem tiv thaiv tus cawv ntawm cov dej noo.
Tsim nyog rau kev siv sab nraum zoov:Feem ntau yog siv hauv kev qhib huab cua, hauv av, thiab nyob rau hauv ib puag ncig nrog huab cua phem.
3. Puas yog siv -2} roj haum rau photovoltaic?
3.1 Kev Siv Tau Siv Siv -2 lables
Raws li cov kev cai ntawm kev siv -2 txheem, siv} {1}} {1} Ua kom muaj qhov kub thiab txias, thiab haum rau txoj kev sab nrauv sab nrauv. Vim tias nws cov dej zoo tsis kam thiab corrosion tsis kam, nws yog qhov tshwm sim hauv av thiab sab nraum zoov. Yog li, tuaj yeem siv {-2} cov cable siv raws li hnub ci cables lossis hnub ci xov hlau?
** Lo lus teb yog:** Siv -2} cable tuaj yeem siv los ua cov cable hauv qee cov photovoltaic hauv qee kis, tab sis nws tsis yog qhov kev xaiv zoo tshaj plaws.
3.2 Kev siv ntawm kev siv -2 nrog photovoltaic yuav tsum muaj
Txawm hais tias siv -2 Cable muaj qee tus yam ntxwv haum rau ib puag ncig sab nraud, nws tseem muaj qee qhov khoob piv nrog lub hnub qub tshwj xeeb. Cov tshuab photovoltait yuav tsum tsuas yog yuav tiv taus qhov kub thiab UV rays, tab sis kuj tseem yuav tiv thaiv tam sim no, tiv taus kev laus, thiab muaj kev ntseeg siab. Hnub ci cables yuav tsum muaj peev xwm hloov kho cov kev ua haujlwm hnyav (xws li 1000v lossis 1500v), thaum siv rau kev sib kis hluav taws xob qis dua.
3.3 Qhov sib txawv ntawm lub hnub ci cirles thiab siv -2 laisles
1. Voltage Theem:Hnub ci cables feem ntau muaj lub zog hluav taws xob theem tuaj yeem ncav cuag qhov hluav taws xob ntawm 100000 lossis 1500v, uas haum rau cov hluav taws xob siab. Qhov voltage theem ntawm kev siv {2}} Cables feem ntau yog 600V, uas tsis haum rau cov photovoltaic uas xav tau ntau voltage.
2. Rwb thaiv tsev kev ua haujlwm:Cov ntaub ntawv rwb thaiv tsev siv nyob rau hauv lub hnub ci clesleshed polyethylene lossis polyvinyl copiaide) yog qhov tshwj xeeb hluav taws xob kev ua haujlwm hauv kev ua haujlwm ntev ntawm photovoltaic. Txawm hais tias lub rwb thaiv tsev ntawm kev siv -2 Cables muaj cov cua sov muaj zog, nws tsis yog tsim tshwj xeeb rau kev siv hluav taws xob ntawm photovoltaic.
3. Cov Qauv Ntawv Pov Thawj:Hnub ci cables feem ntau ntsib cov qauv thoob ntiaj teb xws li cov qauv pa hluav taws xob thiab cov kev pabcuam hluav taws xob rau kev siv hluav taws xob)
4. Kev laus thiab ib puag ncig tsis kam:Cov ntaub ntawv sab nraud ntawm lub hnub ci cable, PE) lossis TPE cov ntaub ntawv, yog cov kev sib pauv qib tshwj xeeb thiab kev laus ntev hauv photovoltaic. Txawm hais tias lub riam tawm sab nraud ntawm kev siv -2 Cables yog UV-resistant yog tsis zoo li tias ntawm cov photovoltaic cables.
4. Kev xaiv kom raug ntawm lub hnub ci clesles
Txawm hais tias siv -2 Cables muaj qee yam hloov kho sab nraum zoov, nws yog qhov zoo tshaj plaws los xaiv cov khoom ua mob sab hnub ci hauv pheeb suab. Tus qauv tsim ntawm photovoltaic cov xaim yuav siv rau cov kev xav tau ntawm lub hnub ci, nrog rau cov muaj zog ntau dua, zoo dua UV tsis kam thiab ntev kev pabcuam lub neej.
Cov Qauv Xaiv rau photovoltaic cables
Kev Ntsuas Qib:Xaiv cov cables tsim nyog rau kev ua haujlwm voltage ntawm lub photovoltaic. Cov hom kev voltage uas muaj 600v, 1000V thiab 1500v.
Cov Qauv Siv:Tooj liab cov kab ke tau ntau dua kev ua haujlwm tau zoo thiab yog li siv tau ntawm cov tshuab photovoltaic. Txawm hais tias txhuas tus cwj pwm tsis kim, lawv muaj kev tsis zoo thiab feem ntau yog siv hauv cov ntawv thov tam sim no.
Ib puag ncig Kuj:Photovoltaic yuav tsum muaj peev xwm tiv thaiv cov mob hnyav xws li muaj zog ur hluav taws xob, siab kub, noo noo, thiab cov tshuaj tsuag. Yog li ntawd, cov riam sab nraud ntawm photovoltaic yuav tsum yog ua los ntawm UV-resistant thiab anti-laus cov ntaub ntawv.
Ua raws li cov qauv:Xaiv lub hnub ci sib luag uas tau ua raws li cov qauv xws li IEC 60216, IEC 60754, thiab lwm yam kom ntseeg tau tias lub cables ntev thiab kev nyab xeeb ntawm cov cables.
