Photovoltaic cable (PV cable) yog txoj cable tsim rau hnub ci photoovoltaic. Nws yog tsuas yog siv los txuas photovoltaic modules (hnub ci ntsa iab) rau inverers lossis roj teeb. Txij li thaum photovoltaic lub tshuab feem ntau ua haujlwm nyob rau hauv sab nraum zoov ib puag ncig, cov kab ke no yuav tsum muaj huab cua zoo, UV tsis kam thiab ua tsis kam. Thaum nws los txog rau kev xaiv ntawm photovoltaic cables, ntsuas hluav taws xob yog ib qho chaw tsis muaj zog.
Kab lus no yuav tham txog cov qauv hluav taws xob photovoltotic ntawm kev nthuav dav, suav nrog cov khoom siv hluav taws xob, cov xov hlau, thiab yuav ua li cas xaiv cov cab kuj haum.
1. Hnub Ci Cable thiab Hnub Ci Hlau
Hnub ci cable yog cable tsim rau photovoltaic (PV). Nws yog feem ntau yog tsim ntawm ntau tus tooj liab lossis txhuas xas thiab nruab nrog lub ntsej muag tawv tawv tawv. Nws yog tsuas yog siv los txuas photovoltaic modules rau inverters, roj teeb cov khoom siv khoom siv lossis lwm yam system. Hnub ci suav tsis tas yuav tsum tau ntsib hluav taws xob ua tau zoo, tab sis kuj yuav tsum muaj cov khoom siv hluav taws xob zoo thiab cov neeg kho tshuab kom yoog tau rau ib puag ncig ntuj ntev.
Hnub ci hlau lo lus no feem ntau hais txog ib daim ntawv ntawm hnub ci cable, tshwj xeeb tshaj yog ib qho xaim xwb. Muaj qee kis, hlau thiab cable yog cov ntsiab lus hloov tau muaj txhij txhua, tshwj xeeb tshaj yog thaum muaj ib xaim hauv cable. Yog li ntawd, muaj qee qhov sib txawv ntawm cov xov xwm hnub ci thiab cov hnub ci hauv txhua hnub, tab sis feem pua yog zoo sib xws - kis hluav taws xob hauv lub tshuab photovoltaic.
2. Voltage theem ntawmpheebsoltaic cables
Thaum xaiv photovoltaic cables, nws yog ib qho tseem ceeb heev kom nkag siab lawv qib voltage. Qhov voltage theem yog qhov siab tshaj plaws uas lub cable tuaj yeem tiv taus thaum siv. Qhov no tsis yog qhia txog hluav taws xob kev nyab xeeb, tab sis kuj cuam tshuam rau kev sib kis tau ntawm lub zog kis thiab ua haujlwm ruaj khov ntawm lub photovoltaic.
2.1 Cov Khoom Siv Hluav Taws Xob uas cov xov tooj hluav taws xob ntawm photovoltaic cables
Cov kab hluav taws xob ntawm cov photovoltotic feem ntau muab faib ua cov hluav taws xob tsawg (qhov hluav taws xob tsawg) thiab ntau voltage). Nyob ntawm thaj chaw sib txawv thiab cov qauv, cov ntsuas hluav taws xob ntawm photovoltaic coables yuav sib txawv, tab sis feem ntau cov hauv qab noCov Hom Kev Feem Ntau:
Tsis tshua muaj hluav taws xob cable:
Nyob rau hauv feem ntau cov chaw lag luam photovoltic tshuab, qhov kev sib tshuam siv hluav taws xob theem yog cov hluav taws xob tsawg. Feem ntau cov cables no tau ntsuas ntawm 600V lossis 1000V. Piv txwv li, cov hnub ci feem ntau cov qauv cable yog pv {2}} f, nrog lub ntsuas hluav taws xob ntawm 1000V DC.
High voltage cable:
Rau qee qhov loj photovoltaic lub zog loj lossis ntau voltage Systems, siab ntau ntau clesh blesles yuav tsum tau ua. Cov ntsuas hluav taws xob ntawm cov cable xws li yog feem ntau 1500v dc. High voltage cables tuaj yeem xa ntau lub zog ntau dua thiab tsim nyog rau kev siv nrog kev sib ntaus ntev ntev.
2.2 Kev sib raug zoo ntawm kev ntsuas hluav taws xob thiab qhov system compression
Lub operating voltoltaic feem ntau yog tsim los ntawm kev sib txuas ntau photovoltaic yog raws li cov ntsuas hluav taws xob ntawm lub photovoltaic modules. Txhawm rau kom muaj kev nyab xeeb ntawm lub cable, thaum xaiv ib qho kev tsim nyog cable, nws yog qhov tsim nyog los xyuas kom meej tias nws cov ntsuas hluav taws xob tsis qis dua qhov kev ua haujlwm siab tshaj plaws ntawm photovoltaic.
Nyob rau hauv lub 600v system, cov ntsuas hluav taws xob ntawm lub photovoltaic cable yuav tsum tau raws li 600V DC.
Hauv 1000V system, cov ntsuas hluav taws xob ntawm lub photovoltaic cable yuav tsum tau ntsib 1000V DC.
Rau ib qho 1500v system, cov ntsuas hluav taws xob ntawm cov cable yuav tsum tau ntsib 1500V DC lossis siab dua.
Xaiv Kev Xaiv PV COPERTAGE theem uas phim lub system voltage tuaj yeem paub tseeb tias cov teeb meem kev nyab xeeb rau hluav taws xob.
3. Hluav taws xob kev ua tau zoo ntawmPV cables
Ntxiv nrog rau qib voltage, PV cov xaim kuj tseem yuav tsum tau ua raws li cov khoom siv hluav taws xob kev ua haujlwm:
3.1 Kev Ua Haujlwm thiab Kev Tawm Tsam
Qhov kev ua haujlwm ntawm lub cable yog ze ze rau cov khoom siv, thiab tooj (CU) lossis txhuas (AL) (AL) (AL) (AL) (AL) (AL) (AL) (AL) (AL) (AL) Tooj liab tau zoo dua, yog li nyob rau hauv tib qho tam sim no thauj khoom, tus ntoo khaub ncaws hla ntawm lub tooj hlau tooj liab cable tuaj yeem ua me me. Tooj liab cov neeg ua haujlwm muaj qis qis, uas pab kom txo lub zog poob thaum lub zog kis.
3.2 rwb thaiv tsev thiab cov ntaub ntawv
Cov rwb thaiv tsev thiab sab nraud cov ntaub ntawv ntawm PV lables yuav tsum muaj cov kub kub kuj, UV tiv thaiv kub, noo noo tsis kam, thiab corrosion tsis kam. Cov ntaub ntawv rwb thaiv cov ntaub ntawv feem ntau muaj cov ntaub ntawv hla sib txuas (XLPinyl
3.3 Qhov ntsuas kub ntawm cov cable
PV cables feem ntau yuav tsum muaj peev xwm hloov kho kom haum rau ntau qhov kev ua haujlwm kub. Feem ntau PVles muaj kev ua haujlwm kub ntau ntawm -40 degree thiab tuaj yeem ua haujlwm nyob rau hauv ib puag ncig kub thiab hloov kho rau ntau yam kev nyab xeeb.
4. Cov Qauv Txheej Txheem rau photovoltaic cables
Tus qauv tsim thiab tsim khoom ntawm photovoltaic yuav tsum tau ua raws li cov qauv hauv cheeb tsam tshwj xeeb thiab cheeb tsam. Cov Qauv Txheej Txheem muaj suav nrog:
IEC 60216:Thermal Kev Ntsuas Ruaj Kuaj Cov Qauv rau Cables.
IEC 60754:Qhia meej txog cov cai yuav tsum muaj rau cov pa luam yeeb ntom nti thiab cov roj corrosive thaum lub sij hawm cable.
UL 4703:American txheem uas qhia meej cov qauv thiab kev ua tau zoo rau photovoltaic cables.
TÜV Ntawv Pov Thawj:Hauv Tebchaws Europe, pheeb suab clescles feem ntau yuav tsum tau ua raws li TÜV ntawv pov thawj kom ntseeg tau tias lawv tuaj yeem siv tau nyob hauv photovoltaic cov ntawv thov.
5. Yuav ua li cas xaiv photovoltaic cables
Thaum xaiv txoj cai photovoltaic cable, koj yuav tsum txiav txim siab ntau yam, suav nrog cov hluav taws xob qib, ntsuas hluav taws xob, ib puag ncig cov xwm txheej, thiab lwm yam.
5.1 Txiav txim siab qhov system voltage
Ua ntej, koj yuav tsum tau xaiv cov ntsuas hluav taws xob ntawm lub cable raws li kev ua haujlwm voltage ntawm photovoltaic. Yog tias lub kaw lus hluav taws xob yog 1000V, tom qab ntawd koj yuav tsum xaiv lub cable nrog txoj kev ntsuas hluav taws xob ntawm 1000v lossis siab dua. Rau ib qho 1500v system, koj yuav tsum xaiv ib qho cable tsim nyog rau 1500v ncaj qha tam sim no (DC).
5.2 Xav txog lub nra tam sim no
Ntxiv nrog rau lub voltage, koj tseem yuav tsum tau xaiv cov kev sib tw cable uas tsim nyog nyob rau ntawm cov kab ke tam sim no. Yog tias qhov chaw hla ntawm lub cable yog qhov me me dhau, nws yuav ua rau lub cable los ua kom sov lossis txawm tias puas. Yog hais tias tus ntoo khaub lig-ntu ntawm lub cable loj dhau, nws yuav ua rau tus nqi. Yog li ntawd, nws yog ib qho tseem ceeb heev kom tsim nyog xam cov kev thauj khoom tam sim no thiab xaiv cov kev sib tw cable-sib txuas.
5.3 Hloov pauv rau ib puag ncig cov xwm txheej
Yuav tsum tau siv cov ntaub ntawv tshaj tawm hauv Phothaet Ntau hom photovoltaic clesles tuaj yeem xaiv nyob ntawm ib puag ncig kev teeb tsa (xws li lub zog hnub ci, cov ntawv vov tsev lossis av).
