Nyob rau hauv xyoo tas los, cov thev naus laus zis hauv kev lag luam photovoltaic tab tom tsim kho sai dua thiab sai dua. Xws li lub zog ntawm ib qho module tau loj dua thiab loj dua. Thiab tam sim no txoj hlua tam sim no tau txais loj dua thiab loj dua. Nrog rau qhov no los txog lub luag haujlwm ntawm PV cable.
Kev tsim qauv qauv thiab cov khoom siv tsim nyog-tsim nyog-tsim nyog tuaj yeem txo cov nqi pib ua haujlwm. Thaum ntawd, Hauv photovoltaic, Daim ntawv thov ntawm high-fais fab siab-efficiiticicum thiab cov khoom sib xyaw tom qab high overmatch. Lub photovoltaic cable yuav tsum yog li cas tsim xaiv.
Xub ZMS ZMS Cable Editor Ua ntej yuav siv koj kom nkag siab Dab tsi yog PV cable. Kab lus no tseem yuav coj koj qee yam kev paub ntawm cov kev xaiv uas tsim nyog ntawm photovoltaic cables.
Hnub ci thev naus laus zis yuav dhau los ua ib qho ntawm lub neej yav tom ntej lub zog thev naus laus zis. Hnub ci zog lossis photovoltaic (Pv) yog nce ntau siv nyob rau hauv Suav teb.
Ntxiv rau kev txhim kho kev txhim kho sai ntawm tsoomfwv cov hluav taws xob photovoltaic fais fab nroj tsuag. Cov tub ua lag luam ntiag tug kuj tseem nquag ua kom cov nroj tsuag thiab npaj muab tso rau hauv ntau lawm hnub ci muag khoom thoob ntiaj teb.
Cov khoom ntawm PVles tau txiav txim siab los ntawm lawv cov kev rwb thaiv tsev cable thiab cov khoom siv sheathing, uas peb hu hla-txuas PE. Tom qab irradiation los ntawm irradiation roj pedal, cov qauv molecular ntawm cov khoom siv cable, yog li muab nws cov khoom ntiag tug.
Qhov tseeb, Thaum nruab thiab tu, Cov cable tuaj yeem nyob rau hauv cov npoo ntse ntawm lub ru tsev qauv.
Nyob rau tib lub sijhawm, Cables yog raug rau siab, dabtsi yog khoov, kev tsis tshuav sib haum, Hla-Tension Loads, thiab muaj zog shocks.
Yog hais tias lub cable sheath tsis muaj zog txaus, Cable rwb thaiv tsev yuav raug puas loj heev, uas tuaj yeem cuam tshuam rau tag nrho cable lub neej lossis ua rau luv luv voj voog, tso tseg, thiab kev raug mob txaus ntshai.
Lub ntsiab ua tau zoo ntawm photovoltaic cables yog qhov ntsuas hluav taws xob.
Kev Ua Hluav Taws Xob Hluav Taws Xob
1 PV Cable DC Kuj
Tiav Cable 20 ℃ Thaum lub DC tsis kam ua DC kuj tsis loj dua 5.09 Huag / km.
2 Immersion Voltage kuaj
Lub tawb tiav lawm (20 m) hauv (20 Ã 5) ℃ Lub sijhawm siv dej raus dej ntawm 1h tom qab 5-min voltage kuaj (Ac 6.5Kv lossis DC 15KV) tsis tawg.
3 Ntev ntev lub sij hawm voltage resistance
Piv txwv ntev ntawm 5 m, mus hauv (85 Ã 2) ℃ Muaj 3% sodium chloride (Nacl) dej distilled (240 Ã 2) h, Ob qho tag kis raug rau cov dej saum npoo 30 cm.
Nruab nrab ntawm cov tub ntxhais thiab dej ntxiv rau DC 0.9KV voltage (Conductive core txuas nrog tus ncej zoo, dej sib txuas nrog tus ncej tsis zoo).
Tom qab noj cov hnoos qeev rau cov dej uas cov kev ntsuas hluav taws xob ntsuas, Qhov kev xeem voltage yog AC 1KV, Qhov yuav tsum tau ua yog tsis tawg.
4 PV cable rwb thaiv tsev tsis kam
Tiav cable rwb thaiv tsev tsis kam ntawm 20 ℃ tsis yog tsawg dua 1014 Huag-cm.
Tiav cable rwb thaiv tsev tsis kam ntawm 90 ℃ tsis yog tsawg dua 1011 Huag-cm.
5 Sheath Nto Kuj
Cov tiav cable sheath nto txwv yuav tsum tsis pub tsawg tshaj li 109 Huag.
Kev Kuaj Ntsuas
1 Kev Ntsuas Siab Kub Siab
Qho so (1403)℃, sij hawm 240 lub min, k = 0.6, indentation tob ntawm tsis ntau tshaj 50% ntawm tag nrho cov tuab tuab ntawm cov rwb thaiv tsev thiab txaj. Thiab AC6.5KV, 5 Min voltage kuaj, Tsis muaj kev yuav tsum tau ua tiav.
2 Ntaj Cua Sov
Cov qauv tso rau ntawm 90 ℃ thiab 85% Tus txheeb ze cov av noo rau 1000h, thiab tom qab txias txias rau chav kub. Qhov hloov pauv ntawm lub zog tensile yog ≤-30% thiab tus nqi hloov ntawm elongation thaum so so yog ≤-30% piv nrog qhov kev xeem.
3 Kev Xeem Sib Xws
Lub cable li tag nrho tom qab 7 × 24h, (135± 2)℃ Kev laus, Rwb thaiv tsev laus ua ntej thiab tom qab tus nqi ntawm kev hloov ntawm Tensile lub zog ≤ 30%, Tus nqi ntawm kev hloov ntawm elongation thaum tsoo so ≤ و ≤. 30%.
Cov tsiaj ua ntej thiab tom qab tus nqi ntawm kev hloov ntawm Tensile lub zog ≤ -30%, Tus nqi ntawm kev hloov ntawm elongation thaum tsoo so ≤ و ≤. 30%.
Yog li, Yuav ua li cas xaiv cov photovoltoltoltoltic tshiab?
Thawj, Rau kev teeb ntawm txoj kab cable, nws tau ua raws li cov kev cai hauv qab no.
1 Zam kev siv tshuab sab nraud, overheating, kev ua cev tub, thiab lwm yam phom sij rau cable.
2 Txhawm rau kom tau raws li qhov yuav tsum muaj kev nyab xeeb nyob hauv cov xwm txheej ntawm cable ua luv.
3 Yooj yim mus pw, kho.
4 Zam rau qhov chaw uas kev tsim kho yuav tau khawb.
5 Cable nyob rau hauv txhua txoj kev tso thiab tag nrho nws txoj kev tshwm sim ntawm sab saud thiab sab laug thiab sab xis hloov chaw, yuav tsum tau raws li cov cable tso cai siv hluav taws xob uas yuav tsum tau ua.
DC cable xaiv los ntawm feem
DC clesles yog ntsia hauv lub hnub, Nws raug nquahu kom xaiv cov cable tshwj xeeb rau phab phab photovoltaics.
Tsis zoo li cov cables dog dig, Cov khoom siv ntawm photovoltaic ntxiv rau REASTRAVIOLET lub teeb thiab ozone.
Thiab tuaj yeem tiv taus qhov kub hloov thiab siv tshuaj lom neeg, thiab tuaj yeem siv sab nraum zoov rau ntau dua 25 lub yim.
Photovoltaic cable qauv yog ntau dua, Tus ntoo khaub lig-ntu ntawm 1.5 m ㎡ rau 35 M ㎡ muaj, Qhov ntau siv yog 4 m ㎡.
Nrog kev nce hauv PV module tam sim no, thiab qhov nce hauv Lub zog ntawm tib inverter. Qhov ntev ntawm lub cable kuj tseem nce, thiab daim ntawv thov ntawm lub 6 M㎡ DC Cable kuj tseem nce.
Nws yog feem ntau pom zoo tias cov kev poob ntawm photovoltaic DC yuav tsum tsis pub tshaj 2%, Thiab peb tuaj yeem tsim qauv thiab xaiv DC cables los ntawm tus qauv no.
Ac Cable xaiv los ntawm Inverter
Los txo tus nqi, Lub PV lub zog cog cov khoom siv thiab cov inverters tam sim no tsis tshua muaj teeb tsa raws li qhov sib piv ntawm 1:1, tab sis raws li lub teeb ci, Xav Tau Feem Ntau, tus lwm yam.
Muaj qee qhov nqi ntawm kev faib tshaj plaws.
Piv txwv, Rau lub zog cog nrog a 1:1.2 kev sib tshooj, tus qauv yog 24kw, nrog 20kw inverter.
Yuav ua li cas xaiv Ac Cable raws li qhov siab tshaj plaws tam sim no ntawm Inverter?
Vim tias txawm li cas los xij, Cov modules tau tshaj-sib phim. Lub inverter muaj kev txwv cov haujlwm tam sim no thiab cov ac tswv yim tam sim no yuav tsis tshaj qhov siab tshaj plaws ntawm cov inverter.
Feem ntau siv ac tooj liab cables rau pv tshuab yog BVR thiab YJV thiab ntau lwm tus qauv.
BVR txhais tau tias Tooj liab cyn Pvc Insulated Yas Siv Hlau, Yjv cross-txuas Polyethylene insulated fais fab cable, Qhov kev xaiv no yuav tsum them sai sai rau qib voltage thiab theem kub ntawm lub cable, thiab yuav tsum xaiv cov nplaim taws retardant hom.
Nov yog qee qhov kev tshawb fawb ntawm kev xaiv ntawm photovoltaic cables. Nrog rau kev loj hlob sai ntawm tib neeg, Qhov kev thov rau cov xaim yuav tsuas tau txais ntau dua thiab siab dua.
Thiab nrog nws, Kev nyab xeeb ntawm cov cable them cov xim tshwj xeeb. Xaiv lub chaw nyab xeeb thiab tsim nyog yog lub luag haujlwm ntawm lub neej.
Tus ZMS Cable Chaw Tsim Tshuaj ib txwm hais txog muab cov xaim siab zoo, Tus nqi zoo rau nyiaj, Xav Txog Kev Pab, thiab cov khoom lag luam uas tau undergone nruj medicual kev tshawb xyuas cov kev txawj ntse thiab yog trustworthy.
