Nrog rau kev txhim kho sai sai thoob ntiaj teb ntawm cov tshuab hluav taws xob photovoltaic (PV) uas tsim hluav taws xob, cov xov hluav taws xob photovoltaic (PV cables)—ua cov khoom tseem ceeb uas txuas cov PV modules, inverters, thiab combiner boxes—ua lub luag haujlwm tseem ceeb hauv kev nyab xeeb thiab lub neej ua haujlwm ntawm lub zog hnub ci. Piv nrog cov xov hluav taws xob ib txwm muaj, cov xov hluav taws xob photovoltaic muaj cov qauv tsim tshwj xeeb thiab kev xaiv cov khoom siv cable.
1. Lub Cable Photovoltaic Yog Dab Tsi?
Ib txoj hlua photovoltaic, tseem hu ua txoj hlua hnub ci lossis PV-specific cable, feem ntau yog siv rau hauv cov chaw tsim hluav taws xob hnub ci, cov tshuab photovoltaic faib tawm, thiab kev teeb tsa PV ru tsev. Cov qauv feem ntau suav nrog PV1-F thiab H1Z2Z2-K, uas ua raws li cov qauv thoob ntiaj teb xws li EN 50618 thiab IEC 62930.
Vim tias cov xov hluav taws xob PV raug rau sab nraum zoov tas li, lawv yuav tsum ua haujlwm tau zoo hauv qab qhov kub siab, muaj zog ultraviolet hluav taws xob, kub qis, av noo, thiab raug ozone. Yog li ntawd, lawv cov kev xav tau rau cov ntaub ntawv rwb thaiv tsev thiab cov ntaub ntawv sheathing siab dua li cov xov hluav taws xob ib txwm muaj. Cov yam ntxwv ib txwm muaj xws li kev tiv taus qhov kub siab thiab qis, kev tiv taus UV zoo heev, kev tiv taus tshuaj lom neeg, kev tiv taus hluav taws, kev phooj ywg ib puag ncig, thiab lub neej tsim los ntawm 25 xyoo lossis ntau dua.
2. Cov Teeb Meem Rau Cov Khoom Siv Cable Hauv Cov Ntawv Thov Photovoltaic
Hauv kev siv tiag tiag, cov xov hluav taws xob photovoltaic feem ntau raug teeb tsa ncaj qha rau sab nraum zoov. Piv txwv li, hauv cov cheeb tsam European, qhov kub thiab txias ntawm cov tshuab PV tuaj yeem mus txog 100 ° C nyob rau hauv cov huab cua hnub ci. Tib lub sijhawm, cov xov hluav taws xob raug rau lub sijhawm ntev UV hluav taws xob, qhov kub thiab txias hloov pauv thaum nruab hnub thiab hmo ntuj, thiab kev ntxhov siab ntawm lub tshuab.
Nyob rau hauv cov xwm txheej zoo li no, cov cables PVC txheem lossis cov cables roj hmab ib txwm tsis tuaj yeem ua haujlwm ruaj khov mus ntev. Txawm tias cov cables roj hmab ntsuas rau 90 ° C ua haujlwm lossis cov cables PVC ntsuas rau 70 ° C kuj yooj yim rau kev laus ntawm cov rwb thaiv tsev, tawg lub plhaub, thiab kev ua haujlwm poob qis sai thaum siv rau hauv cov tshuab photovoltaic sab nraum zoov, ua rau lub neej ua haujlwm ntawm lub kaw lus luv dua.
3. Kev Ua Haujlwm Tseem Ceeb ntawm Cov Xov Tooj Photovoltaic: Cov Khoom Siv Rwb Thaiv Tsev thiab Cov Khoom Siv Sheathing Tshwj Xeeb
Cov txiaj ntsig tseem ceeb ntawm kev ua tau zoo ntawm cov xov hluav taws xob photovoltaic feem ntau yog los ntawm lawv cov khoom siv rwb thaiv tsev PV thiab cov khoom siv sheathing. Cov khoom siv tseem ceeb uas siv niaj hnub no yog cov hluav taws xob crosslinked polyolefin, feem ntau yog ua los ntawm cov polyethylene zoo (PE) lossis lwm yam polyolefins.
Los ntawm kev siv hluav taws xob hluav taws xob, cov saw hlau molecular ntawm cov khoom siv hla kev sib txuas, hloov cov qauv los ntawm thermoplastic mus rau thermoset. Cov txheej txheem no ua rau muaj kev tiv thaiv cua sov, kev tiv thaiv kev laus, thiab kev ua haujlwm ntawm lub tshuab. Cov ntaub ntawv polyolefin uas muaj kev sib txuas hluav taws xob tso cai rau cov xov hluav taws xob photovoltaic ua haujlwm tas li ntawm 90–120 ° C, thaum tseem muab kev ywj pheej zoo heev rau qhov kub qis, tiv thaiv UV, tiv thaiv ozone, thiab tiv thaiv kev tawg ntawm ib puag ncig. Tsis tas li ntawd, cov ntaub ntawv no tsis muaj halogen thiab ua raws li ib puag ncig.
4. Kev Sib Piv ntawm Cov Qauv thiab Cov Khoom Siv: Cov Cables Photovoltaic vs. Cov Cables Ib Txwm Muaj

5. Qhov Sib Txawv ntawm Kev Ua Haujlwm Tseem Ceeb Uas Los Ntawm Kev Xaiv Khoom Siv
Los ntawm qhov pom ntawm tus neeg coj hluav taws xob, cov xov hluav taws xob photovoltaic thiab cov xov hluav taws xob ib txwm muaj zoo ib yam. Qhov sib txawv tseem ceeb yog nyob rau hauv kev xaiv cov ntaub ntawv rwb thaiv tsev thiab cov ntaub ntawv sheathing.
Cov khoom siv rwb thaiv tsev PVC thiab cov khoom siv PVC uas siv rau hauv cov xov hluav taws xob ib txwm muaj feem ntau yog tsim rau sab hauv tsev lossis qhov chaw tsis muaj zog, muab kev tiv thaiv tsawg rau cua sov, kev raug UV, thiab kev laus. Qhov sib txawv, cov khoom siv rwb thaiv tsev polyolefin uas sib txuas nrog hluav taws xob thiab cov khoom siv sheathing siv rau hauv cov xov hluav taws xob photovoltaic yog tsim tshwj xeeb rau kev ua haujlwm sab nraum zoov ntev thiab tuaj yeem tswj tau kev ua haujlwm hluav taws xob thiab kev kho tshuab ruaj khov nyob rau hauv cov xwm txheej ib puag ncig hnyav.
Yog li ntawd, txawm hais tias kev hloov cov cables ib txwm muaj rau cov cables photovoltaic yuav txo cov nqi pib, nws ua rau muaj kev pheej hmoo ntawm kev saib xyuas thiab ua rau lub neej ua haujlwm ntawm lub photovoltaic luv dua.
6. Xaus Lus: Kev Xaiv Khoom Siv Txheeb Xyuas Kev Ntseeg Tau Ntev ntawm PV Systems
Cov xov hluav taws xob photovoltaic tsis yog cov khoom siv hloov pauv yooj yim rau cov xov hluav taws xob ib txwm muaj, tab sis cov khoom siv hluav taws xob tshwj xeeb uas tsim tshwj xeeb rau kev siv photovoltaic. Lawv qhov kev ntseeg tau mus sij hawm ntev yog nyob ntawm kev xaiv cov ntaub ntawv rwb thaiv tsev PV cable thiab cov ntaub ntawv sheathing, tshwj xeeb tshaj yog kev siv cov khoom siv polyolefin uas muaj hluav taws xob sib txuas.
Rau cov neeg tsim qauv PV, cov neeg teeb tsa, thiab cov neeg muab khoom siv cable, kev nkag siab zoo txog qhov sib txawv ntawm cov khoom siv ntawm cov cables photovoltaic thiab cov cables ib txwm muaj yog qhov tseem ceeb rau kev ua haujlwm zoo, ruaj khov, thiab mus sij hawm ntev ntawm cov chaw tsim hluav taws xob photovoltaic.
