Nrog rau kev loj hlob sai ntawm qhov txuas dua tshiab, hnub ci zog tau dhau los ua qhov tseem ceeb ntawm lub zog thoob ntiaj teb. Hnub ci zog nruab nrog muab cov tsev muag khoom huv si, muaj zog rau tsev, lag luam thiab daim phiaj los ntawm kev hloov pauv hluav taws xob hauv kev siv hluav taws xob siv hluav taws xob. Thaum sib tham hnub ci zog, koj feem ntau hnov cov lus "Photovoltaic "thiab" hnub ci", uas feem ntau zoo li tau siv sib hloov hauv kev siv txhua hnub. Txawm li cas los xij, kev tsim qauv sib txawv los xaiv cov khoom siv PV, thiab ua kom muaj kev nyab xeeb system.
Kab lus no yuav ua qhov tob tob tob ib puag ncig ob lub ntsiab lus ntawm "phototoltaic" thiab "hnub ci sib txawv" thiab lub hnub ci sib txawv xws li cov xov hlau photovoltaic thiab hnub ci.
1. Qhov sib txawv ntawm photovoltaic thiab lub zog hnub ci
Txawm hais tias cov lus "photovoltaic" thiab "hnub ci zog" ob leeg muaj kev hloov dua siab tshiab thiab siv cov kev sib txawv ntawm lub hnub ci.
1. Hnub ci zog
"Hnub ci zog" yog lub tswvyim dav dav uas hais txog lub zog tawm los ntawm lub hnub. Lub zog no tuaj yeem hloov dua siab tshiab thiab siv cov khoom sib txawv, tsuas yog thermal zog (hnub ci thermal zog) thiab hluav taws xob photuav (hnub ci photoHovoltaic zog). Hnub ci zog suav nrog kev hloov cov txheej txheem hluav taws xob hauv hluav taws xob, tab sis kuj suav nrog cov hnub ci thermal los rau cua sov, huab cua lossis muab cov cua sov rau cov tsev. Piv txwv li, lub taub hau dej kub hnub ci yog cov cuab yeej uas siv Hnub Ci Cua Txias siv hluav taws xob cua sov, thaum cua sov sov thiab cua sov rau ib lub tsev.
2. Photovoltaic
"Photovoltaic" hais meej tshwj xeeb yog hais txog kev thev naus laus zis uas hloov dua siab tshiab scariation rau hluav taws xob, raws li lub hauv paus ntsiab lus ntawm "photovoltaic nyhuv". Tshuab photovoltaic feem ntau yog muaj cov khoom siv hnub ci, inverers, roj teeb lub zog cia khoom siv lub tshuab thiab lwm yam khoom siv hluav taws xob. Tshuab photovoltaic siv cov khoom hluav taws xob ntawm cov khoom siv hluav taws xob soobuale (AC) Yog li no, photovoltaic tshuab tsuas yog ib qho ntawm cov txheej txheem hnub ci zog siv, tsom mus rau cov hluav taws xob kom muaj hluav taws xob rau hnub ci.
2. Lub luag haujlwm thiab qhov tseem ceeb ntawmpheebsoltaic cablesthiab cov xov hluav taws xob
Hauv photovoltaic, txawm hais tias nws yog lub ru tsev photovoltaic tiam ntawm lub ru tsev uas muaj lub tsev lossis lub xov tooj hluav taws xob loj, cov xov hluav taws xob tsis muaj kuab. Lawv ua ib lub luag haujlwm tseem ceeb hauv kev tuaj yeem hloov kho lub hnub ci, kom txhua lub zog tuaj yeem ua tau zoo thiab muaj kev nyab xeeb los ntawm cov khoom siv hluav taws xob tuaj yeem ua rau cov inverter, hloov chaw lossis daim phiaj.
1. Hnub ci cable
Hnub ci cables yog qhov tseem ceeb ntawm kev sib txuas ntau yam ntawm photovoltaic. Nws muaj ib lossis ntau cov xov hlau uas nqa hluav taws xob tam sim no. Cov qauv ntawm lub hnub ci cables feem ntau suav nrog cov coj ua, cov khaubncaws sab nraud povtseg, sheaths thiab lwm qhov chaw. Tus neeg coj ua feem ntau siv tooj liab lossis cov khoom siv hluav taws xob, thaum lub rwb thaiv hluav taws xob, kev tiv thaiv hluav taws xob, kev kub siab tsis kam thiab lwm yam haujlwm.
Qhov kev ntsuas hluav taws xob ntawm lub hnub ci feem ntau yog 600 / 1000v lossis siab dua (piv txwv, hluav taws xob hluav taws xob ntau ntxiv nrog kev ntsuas hluav taws xob ntawm 3KV lossis siab dua). Nws tus qauv tsim (xws li IEC 60216, U tau ntawv pov thawj, thiab lwm yam) kom muaj kev ntseeg tau thiab ua kom tau raws li cov kev xav tau ntawm photovoltaic nyob rau hauv kev ua haujlwm sib txawv.
2. Hnub Ci Hlau
Lub hnub ci hlau yog ib qho xaim hauv lub hnub ci. Lawv feem ntau yog siv rau kev sib txuas ntawm panels, series thiab kev sib tw sib npaug. Cov xov tooj photovoltaic txawv ntawm cov cable hauv kev tsim. Feem ntau photovoltic cov xov hlau muaj thinner rwb thaiv tsev txheej txheem thiab cov qauv yooj yim vim tias lawv feem ntau siv rau kev tiv thaiv sab hauv zoo li cable.
Zoo ib yam li lub hnub ci cabres, cov khoom tseem ceeb ntawm cov xov hluav taws xob suav nrog kev ua hluav taws xob zoo, UV tsis kam thiab corrosion tsis kam. Cov ntaub ntawv uas siv rau photovoltaic yog tooj liab lossis txhuas, thiab cov ntaub ntawv xws li cov ntoo sib txuas (XLPinyl chloride (PVC) feem ntau yog siv los ua cov txheej txheem rwb thaiv tsev. Cov kav hlau no haum rau cov hluav taws xob me me xav tau, xws li kev sib txuas hnub ci rau inverers lossis lwm yam khoom siv hauv lub photovoltaic.
3. Cov yam ntxwv tseem ceeb ntawm photovoltaic cables thiab hnub ci xov hlau
Lub luag haujlwm ntawm photovoltaic cable thiab hnub ci hauv cov hnub ci yog hais txog cov hnub ci ze, thiab cov ntaub ntawv yuav tsum muaj peev xwm tiv thaiv kev ua haujlwm tshwj xeeb ntawm cov hnub ci. Nov yog qee qhov ntawm lawv cov yam tseem ceeb:
1. Kev kub siab tsis taus
Cov xaim thiab cov xov hlau nyob rau hnub ci lub hnub ci yuav tsum tau tiv thaiv ntev-qhov chaw muaj kub. Tshwj xeeb tshaj yog nyob rau lub caij ntuj sov lossis lub hnub ci muaj zog, qhov chaw kub ntawm lub hnub ci thiab xov hlau yuav ncav cuag 70 qib lossis siab dua. Txhawm rau tiv thaiv cov cables thiab xaim los ntawm kev laus, deforming lossis ntes hluav taws thaum muaj kub, muaj cov khoom siv kub siab yuav tsum raug xaiv. Piv txwv li, hla-txuas Polyethylene (XLPE) yog cov khoom siv uas muaj peev xwm siv tau yooj yim hauv qhov kub thiab txias rau {} degree rau {}}} degree.
2. UV Kuj
Photovoltaic cables thiab cov xov hlau feem ntau raug nthuav tawm sab nraud thiab ntsej muag ncaj qha tshav ntuj, yog li txheej txheej ntawm lub cable yuav tsum muaj UV tsis kam zoo. Lub caij nyoog UV hluav taws xob yuav ua rau laus thiab embrittlement ntawm cov xaim thiab cov xov hlau, feem ntau cuam tshuam rau lawv cov khoom siv hluav taws xob. Txhawm rau txuas lub neej pabcuam, tiv thaiv UV cov khoom siv ntxiv lossis UV-resistant yog txuas ntxiv rau sab nraud ntawm cov tais ntawm cov xov hlau.
3. Corrosion Kuj
Cov tshuab photovoltaic feem ntau tau nruab rau hauv ib puag ncig nrog cov av noo, ntsev tshuaj txau lossis muaj cov pa phem hnyav. Cov xwm txheej ib puag ncig no yuav ua rau corrosion rau cov xaim thiab xov hlau. Corrosion tsis kam yog qhov kev txiav txim siab tseem ceeb thaum xaiv cov photovoltaic cables thiab tus neeg coj ua. Txhawm rau txhim kho corrosion tsis kam, cov kab ke feem ntau siv insulating cov ntaub ntawv nrog cov tshuaj tiv thaiv dej nrog cov polyethylene (xlpe-ntawv pov thawj
4. Cov Tshuab Ntsuas Lub Zog
Txij li lub hnub ci ntsa iab thiab cov xaim yuav tsum tau nruab sab nraum zoov, tshwj xeeb rau hauv av lossis hauv lub cev muaj peev xwm tiv thaiv, kev sib txhuam thiab lwm yam kev ntxhov siab. Cov kab ke zoo photovoltoltaic cables thiab cov neeg coj neeg feem ntau muaj cov tshuab ua kom muaj zog los tiv thaiv kev puas tsuaj thaum lub sijhawm teeb tsa thiab kev ua haujlwm.
4. Xaiv thiab Daim Ntawv Thov ntawm photovoltaic cables thiab hnub ci xov hlau
Thaum xaiv cov photovoltaic cov xaim thiab hnub ci, cov kev xaiv yuav tsum yog ua raws cov ntaub ntawv photovoltaic. Qhov no suav nrog cov hauv qab no:
1. Volfage thiab cov cai tam sim no
Yuav tsum xaiv cov photovoltaic cables thiab cov neeg coj ua raws li kev txiav txim siab raws li cov kev siv hluav taws xob ua haujlwm thiab tam sim no ntawm lub photovoltaic. Piv txwv li, feem ntau ntawm cov lag luam photovoltaic siv cov khoom siv hluav taws xob tsawg (600 / 1000v) Qhov chaw hla ntawm cov xaim thiab cov neeg coj ua yuav tsum raug xaiv raws li cov kev xav tau tam sim no kom muaj kev sib kis tam sim no tsis muaj overheating.
2. Ib puag ncig cov xwm txheej
Thaum xaiv cov photovoltaic cable thiab tus coj ua, koj kuj yuav tsum xav txog qhov chaw teeb tsa. Suav nrog cov khoom xws li ntsuas kub, av noo, UV siv, raug cov tshuaj ntsev lossis tshuaj lom neeg. Piv txwv, photovoltaic cov tshuab nyob rau hauv ntug hiav txwv cheeb tsam yuav tsum xaiv cov cable thiab cov xov hlau uas tiv taus ntsev tshuaj tsuag corrosion; Nyob rau hauv cov kev kub-ib puag ncig, cables uas tiv taus qhov kub thiab UV hluavtaws yuav tsum raug xaiv.
3. Hluav Taws Xob Thiab Cov Neeg Kho Tshuab
Cov khoom hluav taws xob (xws li cov khoom voltage, zoo li lub zog (xws li lub zog tshuab hluav taws xob (xws li cov khoom siv yog qhov tseem ceeb rau kev xaiv. Tshwj xeeb tshaj yog nyob rau hauv loj-scale photovoltaic zog tiam, kev ntseeg tau ntawm cov xaim hluav taws xob cuam tshuam nrog kev ua haujlwm ntev ntawm lub system.
