Hauv lub zog ntawm lub zog niaj hnub no, nrog kev nthuav dav thiab kev txhim kho lub hnub ci zog tiam, kev siv cov photovoltaic cable thiab dog dig kuj tau nce ntxiv. Coob tus neeg yuav raug tsis meej pem txog qhov sib txawv ntawm photovoltaic cables thiab dog dig clesples, tshwj xeeb tshaj yog thaum txhim kho cov nruab hnub ci photovoltaic. Kab lus no yuav tshawb txog qhov sib txawv ntawm photovoltaic cables thiab cov khoom siv zoo li qub, txheeb xyuas cov yam ntxwv ntawm photovoltait, thiab muab qee cov kev yuav khoom.
1. Cov lus txhais ntawmphotovoltaic cable
Photovoltaic cable, raws li lub npe qhia, yog cable tsim tshwj xeeb rau hnub ci photoovoltaic zog ntau tiam tshuab. Nws yog tsuas yog siv rau lub hwj chim sib kis ntawm lub hnub ci thiab inverers, thiab nruab nrab ntawm inverters thiab fais fab rooj lossis khoom siv hluav taws xob. Cov qauv tsim thiab cov ntaub ntawv ntawm photovoltaic suav kom paub tseeb tias lawv tuaj yeem tiv thaiv lub sijhawm ntev, kev kub siab, noo noo, tshuaj lom neeg, thiab lwm yam.
Photovoltaic cov xaim feem ntau yog sib xyaw ntawm peb ntu:Cov neeg xyuas coj, rwb thaiv tsev txheej thiab txheej riam. Nws cov khoom siv neeg xyuas yog feem ntau tooj liab lossis txhuas, thiab cov ntaub ntawv rwb thaiv tsev kom ntseeg tau tias muaj peev xwm ua kom muaj kev cuam tshuam nrog huab cua, kub, cua thiab nag.
2. Cov lus txhais ntawmCables dog dig
Cables dog dig xa mus rau clesnely siv nyob rau ntau lub zog kis thiab tswj lub zog tswj cov tshuab. Cov cables no tsis tsim tshwj xeeb rau lub hnub ci kev lag luam. Cov roj av zoo tib yam tuaj yeem siv tau rau hauv ntau qhov chaw ib puag ncig, thiab lawv cov huab cua tsis muaj zog, thiab tsis tuaj yeem ua tau raws li kev xav tau lub sijhawm ntev thiab ruaj khov ntawm lub zog hluav taws xob.
Cov khoom siv hluav taws xob zoo tib yam tau siv dav hauv cov chaw tsim hluav taws xob, kev sib kis hluav taws xob, kev sib kis tau lub zog, thiab cov hluav taws xob hluav taws xob. Feem ntau, cov ntaub ntawv sheath ntawm cov kab no tsis muaj qhov siv tau UV tsis kam lossis kub tsis zoo, yog li lawv tsis tsim nyog rau kev siv tshav ntuj ncaj qha los yog ib puag ncig loj.
3. Lub ntsiab txawv ntawm photovoltaic cables thiab dog dig cables
3.1 Khoom thiab huab cua Kuj
Lub rwb thaiv tsev txheej thiab txheej ntawm cov photovoltaic feem ntau yog ua cov ntaub ntawv tshwj xeeb, UV tiv thaiv, noo noo tsis kam, thiab corrosion tsis kam. Txij li thaum pheeb suab cables feem ntau yuav tsum tau nruab sab nraum zoov thiab raug rau lub hnub ci rau lub zog ntev, ntsuas kub hloov hluav taws xob, thiab nag hlob. Txhawm rau kom ntseeg tau tias kev ua haujlwm ntev ruaj khov, lub ntsej muag sab nraud ntawm lub xov tooj phab phabsoltaic feem ntau, muaj peev xwm tiv taus kub, kua qaub thiab lwm qhov chaw ib puag ncig.
Hauv kev sib piv, lub riam sab nraud ntawm cov cables dog dig feem ntau yog ua los ntawm cov ntaub ntawv sib xyaw xws li PVC. Txawm hais tias cov ntaub ntawv no tsim nyog rau kev sib kis lub zog hauv sab hauv lossis xeb thaum lub hnub sab nraud thiab dej hiav txwv ntev, yog li lawv tsis haum rau kev siv nyob rau hnub ci zog.
3.2 Cov Khoom Siv Hluav Taws Xob thiab Khoom Hluav Taws Xob
Cov neeg saib xyuas ntawm photovoltaic feem ntau yog ua los ntawm high-purity tooj liab lossis txhuas kom ntseeg tau tias muaj zog hluav taws xob thiab cov hluav taws xob tsis kam. Tooj liab cov neeg ua haujlwm muaj qis dua kev tiv thaiv, yog li lawv tuaj yeem txo cov zog thaum muaj zog, yog li kev txhim kho qhov ua tau zoo tag nrho ntawm cov kab ke. Aluminium tus cwj pwm yog lub teeb thiab tus nqi qis, yog li lawv tseem siv hauv qee cov nqi tsawg.
Cov ntaub ntawv coj los ntawm cov qoob loo dog dig kuj tseem tooj liab lossis txhuas, tab sis lawv cov khoom siv hluav taws xob feem ntau tsis zoo li ntawm photovoltaic cables. Cov hluav taws xob hloov hluav taws xob ntawm cov khoom siv hluav taws xob tsis muaj tseeb los hloov kho rau lub zog hluav taws xob siab, yog li lawv tsis muaj peev xwm tsawg.
3.3 voltage theem thiab cov nyom ntawm daim ntawv thov
Cov xov tooj phab hluav taws xob feem ntau yog tsim rau cov tshuab hluav taws xob high-voltage, tshwj xeeb tshaj yog lub DC voltage em voltage feem ntau yog xyoo 200v mus rau 1000V, lossis siab dua. Txhawm rau tiv nrog cov hluav taws xob siab, pheeb suab cabe muaj hluav taws xob rwb thaiv tsev kev ua tau zoo thiab tuaj yeem tiv thaiv muaj zog hluav taws xob.
Qhov kev sib txawv ntawm cov kab sib txawv raws li kev siv sib txawv, tab sis feem ntau yog siv rau hauv cov khoom siv hluav taws xob tsawg lossis nruab nrab-voltage kis lub tshuab kis.
3.4 Kev Nyab Xeeb Kev Nyab Xeeb thiab Hluav Taws Kub
Kev Nyab Xeeb Kev Nyab Xeeb yuav tsum muaj cov xov tooj phibtoltaic muaj ntau heev, tshwj xeeb tshaj yog cov xwm txheej luv luv thiab ntau dua ntawm kev sib kis tau. Photovoltaic xaim yuav tsum tau muaj kev tiv thaiv muaj peev xwm txaus thiab kev tiv thaiv hluav taws. Txhawm rau kom tau raws li cov kev cai nyab xeeb no, cov ntaub qhwv cov photovoltaic feem ntau ntxiv rau cov qauv hluav taws xob thiab hluav taws kub tiv thaiv kom ntseeg tau tias tsis muaj hluav taws lossis hluav taws xob yuav tshwm sim thaum muaj kev txhaum.
Txawm hais tias Cables dog dig kuj tseem muaj qee yam kev nyab xeeb, feem ntau lawv tsis muaj hluav taws kub tsis kam ntawm photovoltaic cables. Hauv qee qhov chaw muaj kev pheej hmoo siab lossis ib puag ncig tshwj xeeb, cov xov xwm zoo tib yam yuav tsis tau raws li qhov yuav tsum tau ua.
3.5 Lub sij hawm ntev ruaj khov thiab nqa nyiaj
Lub neej tsim lub neej ntawm photovoltaic feem ntau yog ntau tshaj 25 xyoos, uas ntais ntawv cov kev pabcuam lub neej ntawm lub hnub ci zog tiam. Thaum siv sijhawm ntev, pheeb suab ntaub yuav tsum muaj kev ua tau zoo rau ib puag ncig xws li ultraviolet rays, kub hloov pauv thiab noo noo.
Cov kev pabcuam lub neej ntawm cov cab xwm dog dig yog qhov luv luv, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig sab nraum zoov. Cov pob txha dog dig tuaj yeem muaj kev laus, tawg thiab lwm yam teeb meem tsis pub dhau ob peb xyoos, cuam tshuam rau kev ruaj khov thiab kev nyab xeeb ntawm kev sib kis tau.
4. Cov lus qhia tshwj xeeb thiab xaiv cov photovoltaic cable
Cov hlau photovoltaic feem ntau muaj ntau yam specifications, haum rau photovoltaic hwj chim loj thiab hom. Cov hauv qab no yog qee cov photovoltaic Cable specifications:
Voltage theem: Qhov voltage theem ntawm photuav feem ntau yog 600V rau 1500v, uas yog qhov tsim nyog rau cov photovoltaic ntawm cov qib sib txawv.
Nqa khoom tam sim no:Txoj kev nqa khoom tam sim no ntawm photovoltaic sib txawv txawv nyob ntawm qhov chaw hla ntawm cov cable thiab cov khoom coj. Qhov ntau thiab thiab tsawg cable ntau thiab tsawg, 2.5mm², 2.5mm², 4mm², 6mm², thiab lwm yam.
Huab cua Kuj:Lub ntsej muag sab nraud ntawm photovoltaic muaj huab cua zoo dua thiab tuaj yeem tswj tau ruaj khov ua haujlwm nyob rau hauv lub tsheb ulavolet thiab lwm qhov chaw hnyav.
Muaj Feem Qhov Kub:Kev ua haujlwm ntawm qhov ntsuas kub ntawm photovoltaic feem ntau -40 degree rau {}}} degree, ua haujlwm ib txwm muaj nyob rau hauv qhov kub thiab txias.
Thaum xaiv cov photovoltaic cables, ntxiv rau voltage thiab cov lus qhia tam sim no, txawm hais tias xws li cov av noo, thiab lub durability ntawm lub cable yuav tsum tau txiav txim siab. Photovoltaic yuav tsum tau ua raws li kev cuam tshuam thoob ntiaj teb thiab cov qauv kev lag luam, xws li IEC 6016, IEC 60332, thiab lwm yam.
