Raws li lub ntiaj teb xav tau rau lub zog txuas ntxiv ntxiv, hnub ci hluav taws xob tau siv dav hauv tsev, kev lag luam thiab kev lag luam ua ib qho tseem ceeb ntsuab lub zog. Solar photoovoltaic zog cua lub zog rau hauv hluav taws xob lub zog los ntawm lub zog hluav taws xob (PV modules), muab cov neeg siv nrog lub zog huv si thiab muaj zog. Tus qauv tsim thiab teeb tsa ntawm lub hnub ci zog koom nrog ntau yam tseem ceeb, ntawm cov xov hlau thiab hnub ci ua si lub luag haujlwm tseem ceeb. Lawv yog lub luag haujlwm rau kev xa cov hluav taws xob uas cuam tshuam los ntawm lub tog hluav taws xob hnub ci rau cov khoom siv hluav taws xob, roj teeb kom ntseeg tau tias muaj txiaj ntsig zoo thiab kev nyab xeeb ntawm cov photovoltaic.
Thaum xaiv cov cab kuj haum, ntau tus neeg siv yuav nug: uas cov xaim xaim yog haum rau cov panels hnub ci? Puas yog siv cov xov hlau siv tsis siv es ua kua dej siab rau hnub ci? Kab lus no yuav tshawb txog cov khoom siv cov khoom siv hauv cov hnub ci ci, suav nrog lawv cov ntsiab cai ua haujlwm, xaiv cov qauv, los pab koj xaiv qhov yog.
1. Lub ntsiab lus ntawm Hnub Ci Cable thiabHnub Ci Hlau
1.1 Hnub Ci Cable
Hnub ci clesles yog cov cables tsim tshwj xeeb rau cov nruab hnub ci photoovoltaic los txuas cov khoom siv hnub ci, cov inverers, roj teeb thiab lwm yam khoom. Cov qauv tsim ntawm lub hnub ci cables yuav tsum tau siv rau hauv tus account qhov hnyav, noo noo, noo noo, ureposion thiab corrosion resistant cov ntaub ntawv. Cov xov tooj phabsoltait tsis yog yuav tsum muaj cov hluav taws xob zoo, tab sis kuj yuav tsum muaj lub neej kev pabcuam ntev thiab huab cua zoo.
Cov qauv txheem voltuage ntawm lub hnub ci clesles yog 300V, 600V, 1000V thiab 1500v, uas yog qhov tsim nyog rau photovoltaic ntawm ntau qhov sib txawv.
1.2 Hnub Ci Hlau
Cov xov hlau feem ntau xa mus rau cov xov hluav taws xob siv los txuas rau ntau yam hauv cov photovoltaic. Tej zaum lawv kuj tseem yuav yog ib feem ntawm hnub ci cables, tab sis feem ntau lawv yog cov xaim lossis cable. Cov hlau no tau siv hauv cov xov tsawg lossis txuas nrog cov xov hlau nyob rau hauv cov kab ke, thiab feem ntau yuav tsum muaj kev sib cais thiab cov pa hluav taws xob du kev hloov hluav taws xob.
Lub luag haujlwm tseem ceeb ntawm cov xov hluav taws xob hluav taws xob yog los kis cov xov xwm tam sim no los ntawm hnub ci panels rau inverters lossis cov tshuab cia.
2. Ua haujlwm ua haujlwm ntawm lub hnub ci clesles
Tus txheej txheem ua hauj lwm ntawm lub hnub ci clesles yog zoo li lwm hom cables, tsuas yog xa tam sim no thiab voltage. Txawm li cas los xij, vim hais tias cov hluav taws xob hluav taws xob thiab cov khoom siv hnub ci tam sim no yuav tsum tsis txhob muaj kev nyab xeeb thiab ruaj khov thiab lwm yam teeb meem nyob rau hauv cov teeb meem hluav taws xob hnyav.
Qhov tam sim no nyob rau hauv photovoltaic feem ntau yog ncaj qha tam sim no (DC), yog li hnub ci clesables yuav tsum muaj peev xwm mus rau muaj peev xwm hloov dc. Raws li qhov ntsuas ntawm hnub ci lub tshuab nce, tus voltage thiab tam sim no tseem yuav nce ntxiv, uas yuav tsum tau colubs txaus nqa muaj peev xwm thiab conductivity.
3. Cov yam ntxwv tseem ceeb ntawm lub hnub ci cables
Txhawm rau kom tau raws li qhov kev cov nyom ntawm cov nruab hnub ci photoovoltaic, hnub ci cables yuav tsum muaj cov yam ntxwv hauv qab no:
3.1 High voltage nqa muaj peev xwm
Lub tshuab hluav taws xob feem ntau yog li ntawm 1200V, tshwj xeeb tshaj yog nyob rau hauv cov lag luam loj lossis muaj hluav taws xob muaj peev xwm ua tau li 1500v. Txhawm rau kom paub meej lub zog muaj zog, hnub ci cables yuav tsum muaj cov hluav taws xob ntau ntawm 600V, 100v thiab 1500v thiab 1500v thiab 1500v thiab 1500v thiab 1500v thiab 1500v thiab 1500v thiab 1500v thiab 1500v thiab 1500v
3.2 Cov Kub Kub Tsis kam
Hnub ci cables yuav tsum tau nthuav tawm lub hnub ci, yog li qhov kub ua tsis tau yog qhov tseem ceeb. Cov ntaub ntawv rwb thaiv cov hnub ci feem ntau yuav tiv taus qhov kub thiab txias}}} degree, kom lawv tseem ua haujlwm tau zoo nyob rau hauv cov huab cua huab cua huab cua.PV cablesFeem ntau siv cov ntaub ntawv xws li cov ntoo sib txuas nrog Polyethylene (xlpe) kom ntseeg tau tias cov cab tsawg los yog yaj hauv ib puag ncig kub.
3.3 UV Kuj
Hnub ci cables feem ntau yuav tsum tau nruab sab nraum zoov thiab raug rau UV thav duab ntev. Yog tias lub cable tsis yog UV-resistant, nws yuav muaj hnub nyoog sai thiab ua rau lub cable sheath rau kev sib tsoo, cuam tshuam ua rau hluav taws xob tsis ua. Yog li ntawd, cov khoom siv sab nraud ntawm lub hnub ci sib luag feem ntau siv cov hluav taws xob polyethylene (XLPE), uas tuaj yeem tiv thaiv cov kev pabcuam UV thiab txuas ntxiv rau lub neej ntawm lub neej.
3.4 corrosion tsis kam
Hnub ci cables yuav tsum muaj zoo corrosion tsis kam, tshwj xeeb tshaj yog nyob rau hauv cov hiav txwv lossis hauv cov cheeb tsam uas muaj cov av noo hnyav. Qhov cuam tshuam ntawm cov tshuaj corrosive xws li ntsev tsuag, acid los nag thiab tshuaj lom rau cov xaim hluav taws xob tej zaum yuav ua rau cable kev puas tsuaj. Yog li ntawd, hnub ci cables feem ntau siv cov ntaub ntawv tshwj xeeb feem ntau cov ntaub ntawv tiv thaiv corrosion thiab paub meej tias lawv tuaj yeem ua haujlwm stably thiab ntev nyob rau hauv ib puag ncig hnyav.
3.5 hloov pauv thiab siv tau
Hnub ci cables yuav tsum muaj kev hloov pauv zoo thiab tensile lub zog rau kev nqus yooj yim thiab kev kho. Lawv yuav tsum muaj peev xwm tiv thaiv tau ntau dua li khoov thiab ncab yam tsis muaj tawg. Tshwj xeeb tshaj yog thaum npaj cov vaj huam sib luag solar arrays, cables yuav tsum khoov thiab ncab ntawm ntau cov ces kaum, yog li hloov tau thiab ruaj khov yog qhov tseem ceeb heev.
4. Hom ntawm lub hnub ci clesles
Nyob ntawm cov kev xav tau ntawm cov ntawv thov sib txawv, cov kev sib txawv ntawm lub hnub qub ntawm kev ua lag luam tsuas yog suav nrog cov hauv qab no:
4.1 Ib Core Core
Ib qho tseem ceeb cable yog feem ntau siv hom cable hauv photovoltaic thiab feem ntau yog siv rau kev sib kis DC tam sim no. Nws muaj ib tus neeg saib xyuas thiab cov txheej txheem rwb thaiv tsev thiab yog qhov tsim nyog rau kev sib txuas ntawm cov khoom siv li xws li panels, inverers, thiab roj teeb kaw. Ib qho tseem ceeb cable feem ntau yog siv nyob rau hauv cov nruab nrab hluav taws xob thiab muaj qhov yooj yim hloov kho thiab ruaj khov.
4.2 ntxaib core cable
Ntxaib Tub Ntxhais Cables Muaj ob qho ntawm ob tug neeg xyuas thiab haum rau cov xwm txheej uas twv txiaj ntsig tam sim no yuav tsum muaj. Lawv feem ntau yog siv rau kev sib kis ntawm AC zog lossis hauv cov xov tooj photovoltaic, xws li cov tshuab uas yuav tsum tau txuas cov roj teeb thiab cov khoom siv.
4.3 COJ INSULATED CABLE
Txhawm rau txhim kho kev nyab xeeb, ob chav insulated cables ntxiv ntxiv txheej txheej ntawm rwb thaiv tsev rau cov cab kuj. Hom cable no tuaj yeem tiv thaiv kev xau tam sim no thiab ua kom muaj kev nyab xeeb thaum lub hwj chim kis tau. Ob chav insulated cables yog qhov kev xaiv zoo tshaj plaws rau cov hluav taws xob ntau lossis cov tshuab ntim siab.
5. Xaiv cov txheej txheem rau hnub ci clesles
Muaj ob peb yam tseem ceeb los txiav txim siab thaum xaiv lub hnub ci cabar. Nov yog qee qhov ntawm cov ntsiab lus tseem ceeb:
5.1 voltage thiab cov cai tam sim no
Ua ntej, cov hnub ci xaiv yuav tsum muaj peev xwm ntsib tus qauv hluav taws xob thiab cov cai ntawm cov kab ke. Rau cov tshuab me me photovoltaic, cables nrog 600V rau 600V yog feem ntau siv, thaum muaj kev lag luam loj yuav xav tau cables nrog kev ntsuas hluav taws xob ntawm 1000v lossis siab dua.
5.2 ib puag ncig yam
Nyob ntawm ib puag ncig teeb tsa, nws yog ib qho tseem ceeb uas yuav tsum xaiv lub hnub ci txoj cai. Yog tias lub kaw lus nyob sab nraum zoov lossis hauv thaj chaw hiav txwv uas muaj lub hnub ci ncaj qha, cov khoom siv UV-resistant, corrosion-resistant, thiab high-kub-resistant yuav tsum tau xaiv. Rau sab hauv tsev lossis tshuab nyob rau hauv cov chaw me me, dog dig photovoltaic clesles tuaj yeem xaiv tau.
5.3 Cable ntev thiab specifications
Qhov ntev ntawm lub hnub ci cab kuj cuam tshuam rau lub zog poob thiab tag nrho kev ua haujlwm ntawm lub system. Thaum kis tau dhau mus deb, xaiv txoj hlua cable nrog rau ntu loj dua tuaj yeem txo kev poob tam sim no. Feem ntau, cov ntoo khaub lig-ntu ntawm photovoltaic cables yog 4mm², 6 hli, 10mm², uas tau txiav txim siab raws li qhov tseeb tam sim no thiab voltage yuav tsum tau ua.
5.4 Ntawv pov thawj kev nyab xeeb
Xaiv Solar cables nrog cov ntawv pov thawj kev nyab xeeb thoob ntiaj teb (xws li TUV, UL, kev nyab xeeb ntawm cov hluav taws xob, kub thiab lwm yam kev mob hnyav. Cables nrog cov ntawv pov thawj no tau ua tau raws li cov qauv zoo thiab kev nyab xeeb thiab tuaj yeem txo cov kev pheej hmoo ntawm hluav taws, kev sib tw luv, thiab lwm yam.
