Txhawm rau kom muaj kev nyab xeeb thiab kev ua haujlwm ruaj khov, photovoltaic yuav tsum muaj qhov kub muaj peev xwm tiv thaiv qhov kub thiab txias rau {}}}} degree. Hom photovoltic rwb thaiv tsev hlau rwb thaiv tsev cov ntaub ntawv, xws li cross-txuas polyethylene (xlpe) thiab muaj peev xwm ua haujlwm zoo rau lub sijhawm ntev.
3. UV Kuj
Hnub ci lub tshuab feem ntau ntsia sab nraum zoov thiab yog li ntawd yuav tsum tau withstand muaj zog UV hluav taws xob. Lub rwb thaiv lwm sab nraud ntawm photovoltaic feem ntau yuav tsum muaj muaj zog ur ** Hla polyethylene (xlpe) thiab polyolefin (po) ** tuaj yeem ua kom muaj kev ruaj ntseg thiab muaj kev ntseeg siab ntawm lub hnub ci ntev.
4. Corrosion Kuj
Txij li thaum hnub ci lub nruab hnub qub yog nthuav dav los yog los nag ib puag ncig, cov xov hlau los nag yuav tsum muaj cov dej tsis kam thiab xeb tsis kam. Qhov tshwj xeeb hauv dej hiav txwv, thaj chaw ntug dej hiav txwv lossis kev siv tshuaj tiv thaiv kab mob ntawm cov xov tooj ntawm cov ntsev, acid los nag thiab lwm yam tshuaj. ** Cov ntaub ntawv xws li Cross-Txuas Polyethylene (XLPE) thiab tseem muaj kev tiv thaiv tsis txaus siab, tab sis kuj tseem muaj kev tiv thaiv mob hauv cable thiab ua kom muaj kev ruaj khov ntev ntawm cov kab ke.
5. Txhua yam kev ntxhov siab tsis kam
Hnub ci cables thiab cov xov hlau feem ntau yuav tsum muaj kev ntxhov siab xws li lub cev kom nruj, kev sib txhuam, thiab khoov. Txhawm rau tiv thaiv cable kev puas tsuaj lossis hluav taws xob thaum lub sijhawm teeb tsa thiab kev ua haujlwm, cov xov hlau yuav tsum muaj lub zog kho tshuab. Qhov no yuav tsum tsis tsuas yog cov khoom siv siab ntawm lub xaim nws tus kheej, tab sis kuj tseem tawm tsam kev sib txhuam, tiv thaiv txheej txheem ntawm cov rwb thaiv tsev txheej thiab sheath. High-zoo photovoltaic feem ntau siv cov ntaub ntawv rwb thaiv tsev ua kom zoo dua thiab raug kho tshwj xeeb los txhim kho lawv txoj kev tiv thaiv rau kev puas tshuab puas.
6. Hluav taws xob rwb thaiv tsev
Cov rwb thaiv tsev kev ua haujlwm ntawm photovoltaic xaim yog tus yuam sij los ua kom muaj kev nyab xeeb ntawm cov kab ke. Lub rwb thaiv tsev txheej tsis tsuas yog tiv thaiv kev xau tam sim no, tab sis kuj tau zam cov hluav taws xob kev cuam tshuam los ntawm kev sib tshooj tam sim no, xws li Arcs thiab luv voj voog. Lub rwb thaiv tsev txheej ntawm photovoltaic feem ntau siv cov ntaub ntawv siv hluav taws xob polyethylene (XLPINY) lossis muaj peev xwm zam kom zam cov dej xau thiab hluav taws xob tsis txaus.
3. Qhov kev sib raug zoo ntawmHnub ci cablesThiab photovoltaic xov hlau
Hauv photovoltic cov tshuab, ** Hnub ci lub zog (hnub ci cable) feem ntau yog hais txog cov xaim hluav taws xob, thaum lub xov tooj pheeb suab (PV xaim) ** Xa mus rau cov xov hlau ib leeg (PV hlau) ** Xa mus rau cov xov hlau ib leeg hauv cables. Hnub ci cables yog teeb meem ib qho txuas uas txuas rau ntau yam ntawm photovoltaic tshuab ua ke. Lawv muaj cov qauv ntawm tus neeg saib xyuas thiab cov khaubncaws sab nraud povtseg. Cov xov tooj photovoltaic yog ib qho xov xwm ib leeg ua lub luag haujlwm rau kev kis tau tam sim no hauv cables.
Piv txwv li, hnub ci ntsa iab hauv photovoltaic feem ntau txuas nrog inverers los ntawm cov cable, txhua tus ua lub luag haujlwm sib txawv hauv lub zog kis cov txheej txheem. Txhawm rau kom muaj kev nyab xeeb thiab kev ua haujlwm ruaj khov ntawm cov xov tooj pheeb suab, lub hnub ci cables thiab photovoltaic yuav tsum muaj kev ua tiav txaus, kev ua haujlwm rwb.
4. Daim ntawv thov thiab xaiv ntawm photovoltaic xaim
Hauv photovoltaic, photovoltaic feem ntau yog siv rau cov ntawv thov hauv qab no:
Txuas cov photovoltaic panels thiab inverters
Cov xov tooj photovoltaic feem ntau yog siv los txuas cov panels ci ntsa iab thiab inverters, lub luag hauj lwm rau kev xa mus rau hauv inverter thiab hloov nws mus rau hauv AC fais fab. Cov xov hlau zoo li no yuav tsum muaj kev coj ua zoo thiab rwb thaiv tsev kom ntseeg tau lub zog ruaj khov thiab kev nyab xeeb system.
Series thiab cov kev sib txuas sib txuas
Nyob rau hauv pawg vaj huam sib luag solar arrays, photovoltaic cov xov kuj yuav tsum ua lub luag haujlwm ntawm series thiab sib piv. Los ntawm cov kab txuas ntxiv, lub voltage ntawm lub vaj huam sib luag tuaj yeem nce ntxiv; Los ntawm cov kev sib txuas thaum ub, tam sim no ntawm lub vaj huam sib luag tuaj yeem nce ntxiv. Thaum txuas cov lauj kaub no, photovoltaic yuav tsum xyuas kom cov kev sib kis ntawm tam sim no thiab hluav taws xob tsis yog cuam tshuam.
Kev sib txuas lus ntawm photovoltaic system
Cov ntaub ntawv xa tawm (xws li cov chaw faib khoom, hloov, thiab lwm yam) hauv photovoltaic kuj yuav tsum tau txuas los ntawm photovoltaic cov xov hlau kom ntseeg tau tias yuav muaj qhov kis tau thiab faib lub hwj chim hauv tag nrho cov kab ke. Qhov kev xaiv ntawm photovoltaic yuav tsum tau txiav txim siab raws li qhov hluav taws xob, ib puag ncig tam sim no thiab kev nyab xeeb thiab kev nyab xeeb ntawm cov haujlwm.
Daim phiaj kev sib txuas
Rau cov xov tooj hluav taws xob loj photovoltaic, photovoltaic hluav taws xob kuj yuav tsum tau txuas nrog cov phiaj los pub hluav taws xob rau hauv kab sib chaws. Hauv cov txheej txheem no, cov kav hlau tsis tas yuav tsum nqa cov dej khov siab xwb, tab sis kuj tseem yuav tsum muaj cov rwb thaiv tsev zoo thiab huab cua tsis kam los tiv thaiv kev ua tsis tiav vim yog lwm yam sab nraud.
Kev Xaiv Xaiv
Thaum xaiv cov xov tooj photovoltaic, cov ntsiab lus hauv qab no yuav tsum tau txiav txim siab:
