Nyob rau hauv lub ntiaj teb ntawm hnub ci zog, ib qho tseem ceeb uas ua kom muaj kev lag luam du thiab ua haujlwm zoo ntawm lub photovoltaic (PV) system yog tusHnub Ci CableUas txuas cov hnub ci ntsa iab rau inverter thiab lwm yam system. Raws li hnub ci zog hluav taws xob feem ntau yog nruab rau hauv ib puag ncig sab nraum zoov, huab cua, thiab lwm cov huab cua lub hnub ci yog qhov tseem ceeb heev. Qhov no suav nrog ua kom muaj kev ua kom muaj kev ua kom lub hnub ci yog UV-resistant thiab tuaj yeem tiv taus qhov kev mob hnyav.
Ib qho xws li nrov nrov cable siv nyob rau hauv photovoltaic cov ntawv thov yog PV 1- fable. Paub txog nws lub zog thiab yoog raws, lub pv {{1} f Cable feem ntau siv rau cov hnub ci ntsa iab thiab hnub ci zog ua haujlwm nruab. Txawm li cas los xij, ib yam li muaj tej hnub ci ntsa iab, nws yog ib qho tseem ceeb kom ntsuas seb puas tau ntsuas cov qauv rau UV tsis kam thiab sab nraum zoov. Hauv tsab xov xwm no, peb yuav delve rau hauv UV tiv taus ntawm PV {} f cable rau sab nraum zoov hauv ntau qhov chaw nruab nrab.
1. Dab tsi yogPV 1- f Cable?
PV {{{{{{0} f clesh me me tau tsim tshwj xeeb rau siv hauv photovoltaic thiab muaj feem ntau siv los txuas cov khoom siv hluav taws xob lossis lwm yam system. Kev tsim kho ntawm PV {{{1} f cocks (XLPE) Rwb thaiv tsev txheej, thiab LSZH (tsawg pa taws xoom halogen) cov ntaub ntawv. Cov cable no yog tsim los ua kom tau raws li cov qauv hauv ntiaj teb, kom lawv muaj kev nyab xeeb, txhim khu kev qha, thiab ua tau zoo rau kev siv hauv lub hnub ci nruab.
Lub PV 1- f Cable yog tsim los siv cov hluav taws xob kev xav tau ntawm cov hnub ci, suav nrog lub peev xwm los nqa cov dej khov loj los ntawm cov hnub ci loj. Cov Cables yog hloov tau thiab lub teeb ci, ua rau lawv yooj yim rau nruab rau hauv ob qho chaw nyob thiab hnub ci nruab hnub.
2. UV tsis kam nyob rau hauv lub hnub ci clesles: ib qho tseem ceeb
Ib qho ntawm cov yam ntxwv tseem ceeb tshaj plaws siv rau hauv lub hnub ci hluav taws xob yog lawv lub peev xwm tiv taus ultraviolet (UV) hluav taws xob. UV hluav taws xob yog ib feem ntawm lub hnub ci uas tuaj yeem txwv cov ntaub ntawv hauv lub hnub ci hauv lub sijhawm, ua raws li cov rwb thaiv tsev thiab cov ntaub ntawv pov thawj. Raws li cov panels hnub ci feem ntau yog ntsia hauv cov chaw sab nraud sab nraud, qhov chaw uas lawv tau nthuav tawm ntawm cov kab txuas mus ntev, UV tsis kam lees kom ntseeg tau ntev.
UV tsis kam nyob rau hauv lub hnub ci cuas hais txog lub peev xwm ntawm cov khoom siv cable - tiv thaiv kev puas tsuaj, tawg, lossis poob lawv cov hauj lwm zoo. Yog tias lub hnub ci xaim tsis yog UV-resistant, nws tuaj yeem ua rau rwb thaiv tsev denpadation, hluav taws xob ua txhaum, lossis hluav taws kub nyhiab.
2.1 Yuav ua li cas UV tiv taus ua haujlwm
UV tsis kam ntawm cov nplhaib ci ntsa iab yog feem ntau txiav txim siab los ntawm cov khoom siv siv rau cov rwb thaiv tsev thiab sab nraud. Cov ntaub ntawv zoo li XLPE (Hla-txuas Polyethylene) thiab LSZH (tsawg pa taws qhov xoom Halogen) yog qhov tshwj xeeb tshaj yog paub txog lawv lub peev xwm tiv taus UV degradation. Cov ntaub ntawv no tau kho lossis tsim txoj hauv kev uas lawv tsis txhob tawg yooj yim thaum raug rau lub hnub ultraviolet thiab tiv thaiv lub cable los ua kev tawg lossis tawg.
Thaum lub hnub ci ci yuav raug rau UV hluav taws xob, cov hlua khi ntawm cov lwg me me ntawm cov khoom tuaj yeem tsis muaj zog, ua rau cov khoom siv tsis muaj zog, ua rau cov khoom siv tsis muaj zog, ua rau cov khoom siv tsis muaj zog, ua rau cov khoom siv tsis muaj zog, ua rau cov khoom siv tsis muaj zog, ua rau cov khoom siv tsis muaj pa. Cov txheej txheem no yog lub npe hu ua photodegradation. UV-resistant cov ntaub ntawv siv hauv cov xaim no los nqus lossis cuam tshuam UV hluav taws xob, txo qhov kev cuam tshuam ntawm kev kis tau ntawm lub caij nyoog dhau sijhawm.
3. YogPV 1- f CableUV-resistant?
PV {{{{{{0} f Cable yog tsim nrog UV tsis kam raws li cov tseem ceeb ntawm kev teeb tsa sab nraum zoov xws li rooftop hnub ci nruab hnub ci thiab hnub ci liaj teb thiab hnub ci. Lub ntsej muag sab nraud ntawm PV {{1} f cables yog feem ntau yog ua los ntawm pvc (LSZH (qis pa taws xoom Halogen), ob qho tib si muab kev tiv thaiv UV.
3.1 Pvc thiab UV Kuj
PVC, ib qho ntawm cov khoom siv feem ntau siv rau cable sheaths, yog inherently UV-resistant. Thaum siv nyob rau hauv lub hnub ci clesles, PVC tau kho tshwj xeeb kom peb tuaj yeem tiv taus lub hnub ci kom tsis txhob tawg lossis poob nws cov hauj lwm zoo. PV {{{{2} f cleshs ua nrog pvc sheath yog yog li ntawd muaj kev tiv thaiv UV, ua rau lawv haum rau ib puag ncig sab nraum zoov.
3.2 LSZH THIAB UV Kuj
Lwm qhov kev xaiv rau hnub ci cables yog LSZH (tsawg pa taws xoom halogen), cov ntaub ntawv siv hauv qee lub PV {{f cables. LSZH yog qhov muaj siab heev rau ob lub UV hluav taws xob thiab cov huab cua huab cua ib puag ncig. Nws tau txais txiaj ntsig tshwj xeeb rau kev teeb tsa qhov kev nyab xeeb yog kev txhawj xeeb, raws li nws tso pa taws tsawg thiab tsis muaj tshuaj lom nyob rau hauv qhov xwm txheej. Zoo li PVC, LSZH muab cov uv tsis kam, ua kom muaj kev txhim khu kev ntseeg tau thiab txhim kho sijhawm dhau sijhawm.
4. Haum rau PV 1- fable rau sab nraum zoov
Muab hais tias PV {{{{{{0} f cables yog UV-resistant, lawv yog qhov haum rau kev siv sab nraum zoov. Cov cable no yog tsim los tiv thaiv cov kev nyuaj ib puag ncig uas muaj kev kub ntxhov, thiab lwm yam kev mob hnyav uas nyob hauv kev sib txawv sab nraum zoov.
4.1 Ib puag ncig tsis kam
Ntxiv rau UV tiv taus, PV {{{{{m Qhov no ua rau lawv zoo tagnrho rau siv nyob rau hauv ntau qhov chaw, suav nrog hnub ci ua liaj ua teb, kev lag luam rooftOP teeb tsa, thiab cov vaj huam sib luag solar systems.
Qhov ntsuas kub ntau: PV {{{1- f cleshes muaj kev ua haujlwm ntau los ntawm {2}} degree, los ntawm qhov txias heev rau ib puag ncig kub heev.
Dej tiv: Cov cables yog tsim los tiv thaiv dej ingress, kom lawv tswj tau lawv cov hluav taws xob hluav taws xob txawm tias muaj cov xwm txheej ntub.
NEEG KHO TSHUAB DURISHAB: Cov ntaub pua av sab nraud siv hauv PV {{}} f cabs-resistant, tso cai rau lub cev kom tiv thaiv thiab kua muag thaum lub sij hawm teeb tsa lossis kev ntxhov siab.
4.2 Ntev Lub Sij Hawm
UV-resistant cov khoom ntawm PV 1- f cleshidess kom lawv tuaj yeem tswj lawv cov txiaj ntsig ntev, txawm tias thaum muaj hnub ci. Tus ntoo khaub lig-txuas Polyethylene (XLPE) Rwb thaiv tsev cov khoom siv nyob rau hauv PV} f cables yog tsim los ntawm lub hnub ci thiab tshwm sim rau hnub ci thiab kub. Qhov no ua rau muaj lub neej kev pabcuam ntev rau lub sijhawm ua haujlwm ntev rau cov kav dej hnub ci siv hauv ib puag ncig sab nraum zoov, ua rau lawv xaiv ruaj khov thiab txhim khu kev qha rau lub ntiaj teb vaj huam sib luag.
5. Vim li cas UV tsis kam yog qhov tseem ceeb rau hnub ci cable kev ua tau zoo
Rau hnub ci cables zoo li PV 1- f, UV tsis tseem ceeb rau ntau yam:
Tiv thaiv rwb thaiv tsev: UV hluav taws xob tuaj yeem ua rau cov rwb thaiv tsev ntawm cov cable los tsoo lub sijhawm, uas tuaj yeem ua rau hluav taws xob ua txhaum, luv, lossis txawm tias hluav taws phom sij. PV {{{1- f Cables
Tswj kev nyab xeeb: UV-resistant clesles cuam pab txo cov kev pheej hmoo cuam tshuam nrog cable kev puas tsuaj vim muaj kev nyab xeeb ntawm tag nrho hnub ci zog.
Txuas txuas ntxiv siv nyiaj: UV-resistant cables ntev thiab yuav tsum muaj kev txij nkawm, muab kev cia siab ntev thiab txo nqi nyiaj tau los ntawm lub neej ntawm lub cev.
Txhim Kho Txheej Txheem Zog: Cov qoob loo uas tuaj yeem tiv thaiv UV hluav taws xob tswj lawv cov kev ua tau zoo thiab kev ntseeg tau, uas yog qhov tseem ceeb ntawm lub zog ntawm lub hnub ci zog.
6. Kuaj thiab Qauv rau UV Kuj
Txhawm rau kom cov UV tiv thaiv ntawm PV 1- f cables, cov qauv lag luam ib txwm ua rau cov qauv thoob ntiaj teb uas ntsuas lub peev xwm tiv thaiv UV kis. Cov ntawv xeem muaj xws li:
Iso 4892-2: Qhov kev ntsuas no UV tiv thaiv ntawm cov yas, simulating ntev UV kis tau.
IEC 60216: Tus qauv no ntsuas cov thermal thiab UV ruaj khov ntawm cov ntaub ntawv siv hauv cov cable.
En 50525-3-41: Raws li yav tas los hais txog, cov txheej txheem no muab cov kev qhia tshwj xeeb rau hnub ci clesles, suav nrog UV tsis kam thiab lwm tus yam ntxwv ib puag ncig kev ua yeeb yam.
Los ntawm kev sib ntsib cov qauv no, PV {{{{{{} f clesh bles ua rau lawv haum rau kev siv sab nraum zoov ntev hauv kev sib tw hnub ci.
