Thaum nws los txog Hnub Ci Cables thiab cov xov xwm hnub ci, cov ntaub ntawv rwb thaiv tsev yog cov khoom siv rau kev nyab xeeb, ua haujlwm, thiab kev ntseeg tau ntawm txoj hlua cable. Ntawm cov clescles ntau yam siv hauv photovoltaic (PV), lub PV 1- f Cable khoom siv, ua tsaug rau nws cov kev ua tau zoo tshaj plaws hauv lub zog hnub ci. Ib qho ntawm cov tseem ceeb ntawm PV {{1} f Cable yog nws lub luag hauj lwm tseem ceeb hauv kev tiv thaiv ib puag ncig sab nraud ntawm sab nraud.
In this article, we will explore the insulation material used in PV1-F cables, discussing its properties, advantages, and why it is chosen for solar applications. Tsis tas li ntawd, peb yuav sib piv pv {{1} f cables nrog lwm cov ntaub ntawv rabding thiab lawv cov txiaj ntsig zoo ntawm PV {2}} f cables.
1. Txheej txheem cej luam ntawmPV 1- f Cable
Ua ntej dhia rau hauv cov ntaub ntawv rwb thaiv tsev, cia peb nkag siab cov yam ntxwv thiab lub hom phiaj ntawm PV {{mle.
Lub PV 1- f Cable yog ib hom hnub ci cable uas tau tsim tshwj xeeb los siv hauv photovoltaic (hnub ci). Cov cables txuas cov panels hnub ci mus rau inverter, roj teeb kaw cov tshuab, thiab lwm yam ntawm lub zog hnub ci. Lub PV 1- f Cable yog tsim los nqa ncaj qha tam sim no (DC) hluav taws xob, thiab kis los ntawm cov khoom siv hnub ci, thiab muab cov khoom siv hluav taws xob zoo thiab muaj kev nyab xeeb.
Cov yam ntxwv tseem ceeb ntawm PV 1-} f cables:
Kev Ntsuas Hluav Taws Xob: Feem ntau ntsuas txog li 1, 000 v dc, uas haum rau feem ntau ntawm cov nruab nrab thiab cov hnub ci hluav taws xob.
Qhov ntsuas kub ntau: Tuaj yeem ua haujlwm hauv qhov kub thiab txias ntawm -40 degree rau +90 degree, uas ua kom muaj txiaj ntsig zoo hauv kev ua haujlwm ntau ntawm ib puag ncig.
UV Kuj: Tsim kom tiv thaiv lub caij nyoog raug tshav ntuj, ua rau nws zoo rau sab nraum zoov.
Yooj yooj: Hloov pauv tau thiab yooj yim rau nruab, tshwj xeeb tshaj yog hauv cov txheej txheem nyuaj lossis qhov chaw tiv thaiv kom ncav cuag.
2. Rwb thaiv cov ntaub ntawv ntawm PV 1- f Cable
Lub rwb thaiv tsev cov khoom siv nyob rau hauv PV {{{0} f clese ua kev tiv thaiv tus neeg saib xyuas thiab ua kom muaj kev nyab xeeb ntawm lub hnub ci hla nws lub zog ntev. Lub rwb thaiv tsev pabcuam kom tiv thaiv luv luv ncig, hluav taws xob, thiab hluav taws kub nyhiab los ntawm kev cais hluav taws xob tam sim no sab hauv.
Cov khoom siv insholdion siv nyob rau hauv PV 1- f Cable yog hla cov ntaub ntawv xws li thermoplastic elastomers (tpe). Cia peb tsoo cov khoom thiab cov txiaj ntsig ntawm cov ntaub ntawv no:
2.1 Hla-Txuas Polyethylene (XLPE)
XLPE yog hom polyethylene (PE) uas tau undergone cov txheej txheem tshuaj lom neeg hu ua kev sib txuas lus, uas muaj feem cuam tshuam txog kev sib khi ntawm cov saw polymer. Cov txheej txheem no tau txhim kho cov khoom siv lub cev thiab thermal ntawm cov khoom, ua rau nws haum ib puag ncig zoo li hnub ci nruab.
Cov khoom ntawm XLPE rwb thaiv tsev:
Cov hluav taws xob hluav taws xob hluav taws xob: XLPE yog cov khoom siv hluav taws xob zoo, muab cov khoom siv zoo dua rau hluav taws xob tam sim no. Qhov no ua kom pom tseeb tias lub PV {{0} fable} Fable tuaj yeem nqa lub siab dc voltages uas tsis muaj kev pheej hmoo ntawm kev xau lossis luv luv voj voog.
Thermal ruaj khov: Ib qho ntawm cov khoom sawv ntawm XLPE yog nws lub peev xwm ua kom muaj kev kub ntxhov siab. XLPE muaj qhov siab ntsuas hluav taws xob thiab tuaj yeem ua haujlwm tau zoo nyob rau hauv cov huab cua sov heev, xws li {{} degree rau {{1} degree. Qhov no ua rau pv 1- f clesles zoo tagnrho rau kev siv sab nraum zoov, qhov twg cua hloov pauv ntau yam.
UV Kuj: Txij li PV {{{{1- f cables feem ntau siv nyob rau hauv hnub ci nruab hnub, lawv yuav tsum tau tiv taus ultraviolet (UV) hluav taws xob los ntawm lub hnub. XLPE paub txog nws lub zog UV Kuj, ua kom cov khoom siv rwb thaiv tsev tsis ua rau lossis poob nws lub hnub ci thaum lub hnub ntev.
Tshuaj Kuj: XLPE muaj kev tiv thaiv zoo rau cov neeg sawv cev tshuaj thiab noo noo, uas yog qhov tseem ceeb rau cov xaim hluav taws xob uas lawv tuaj yeem raug rau ntau yam tshuaj lom neeg, ntsev, thiab dej. Qhov kev tiv thaiv no tiv thaiv cov rwb thaiv tsev los ntawm kev rhuav tshem thiab ua kom pom kev ntev ntawm kev sib txuas.
NEEG KHO TSHUAB DURISHAB: Cov txheej txheem hla kev uas muab rau XLPE nws lub npe kuj pab tau nws cov khoom siv neeg kho tshuab, xws li lub zog tensile thiab cuam tshuam tsis kam. Qhov no ua rau pv {{1} f cab lo tiv thaiv lub cev thiab kua muag, suav nrog ua kom muaj kev puas tsuaj, thiab ua rau muaj kev sib cais txawm tias muaj qhov sib zog txawm tias muaj teeb meem sib xyaw.
Nplaim taws retardancy: XLPE yog inherently nplaim taws, lub ntsiab lus uas nws yuav tsis ntes hluav taws yooj yim thiab yuav tus kheej-extinguish thaum cov nplaim hluav taws. Qhov no yog cov cuab yeej tseem ceeb rau txhua lub hnub ci cable, raws li nws pab tiv thaiv cov phom tua hluav taws thaum muaj hluav taws xob ua txhaum lossis raug xwm txheej.
2.2 Thermoplastic elastomers (TPE)
Qee lub PV {{{1- f cleshes yuav siv tpe li cov ntaub ntawv rwb thaiv, tshwj xeeb yog tsim yooj lossis cov ntawv thov siab. TPE yog sib xyaw ntawm thermopicast cov ntaub ntawv thiab elastomers, uas muab ob qho tib si hloov kho thiab siv tau.
Cov khoom ntawm tpe rwb thaiv tsev:
Yooj yooj: TPE yog hloov tau yooj yim, ua kom yooj yim dua rau nruab rau thaj chaw nrog kev xav tau khoov ntawm cov fab lossis cov nyom. Qhov no ua rau TPE-insulated cables zoo tshaj plaws rau kev teeb tsa qhov twg cable yuav tsum tau nyob ntawm cov chaw nruj.
UV thiab huab cua Kuj: TPE kuj tseem muaj UV tsis kam zoo thiab yog tsim kom tiv thaiv kev raug rau sab nraum zoov cov khoom xws li tshav ntuj, nag, thiab cua. Qhov no ua kom ntseeg tau tias hnub ci cables siv lub rwb thaiv tsev tpe tuaj yeem ua kom muaj kev ywj pheej hauv kev sib tawm sab nraum zoov.
Tsawg qhov cua sov yooj yim: Tsis zoo li ib teev thermoplastics, TPE tseem hloov pauv txawm tias tsis muaj qhov kub tsawg. Qhov no ua rau nws haum rauHnub Ci HlauInstallations nyob rau hauv cov huab cua txias.
Neeg Kho Tshuab Muaj Zog: TPE muab kev tiv thaiv zoo heev, muab qib siab ntawm kev tiv thaiv kev cuam tshuam, puas tsuaj, thiab lwm yam kev nyuaj siab lub cev.
3. Qhov zoo ntawm kev siv XLPE rwb thaiv tsev hauv PV 1-} f cables
Kev siv XLPE raws li thawj cov khoom siv rwb thaiv tsev hauv PV {{{}} f Cables muab ntau cov txiaj ntsig tseem ceeb:
Lub Neej Muaj Kev Pab Ntev: Kev sib xyaw ntawm cov hluav taws xob zoo, cov cua sov, thiab cov tshuab cua sov kom ntseeg tau lub neej zoo, ib txwm muaj 25 xyoo nyob rau hauv feem ntau lub hnub ci lub nruab nrab. Lub rwb thaiv tsev tsis kam rau UV hluav taws xob, huab cua, thiab tshuaj lom neeg kom ua kom muaj kev ntseeg tau tias lub cable yuav ua tau zoo thoob plaws nws lifespan.
Kev Nyab Xeeb Kev Nyab Xeeb: XLPE rwb thaiv tsev muaj kev tiv thaiv cov khoom muaj zog hluav taws xob, suav nrog kev pheej hmoo ntawm hluav taws xob, thiab hluav taws kub. Nws cov nplaim taws-retardant thaj chaw xyuas kom meej tias PV 1- f clescase pab txhawb kom muaj kev nyab xeeb hnub ci zog.
Txhim Kho Kev Ua Tau Zoo: Los tiv thaiv kev tiv thaiv lub zog vim yog dej xau, cov xlpe rwb thaiv tsev pab tswj cov kev ua tau zoo ntawm lub hnub ci. Qhov no muaj peev xwm ua rau tag nrho cov khoom siv hluav taws xob tag nrho ntawm lub hnub ci zog, kom muaj zog uas tau tsim los ntawm lub hnub ci kho tau zoo rau cov inverter thiab lwm yam.
Nqi zog-ua hauj lwm: Thaum lub rwb thaiv tsev XLPE yuav kim tshaj li cov ntaub ntawv thermopoplastic, nws qhov kev ua tau zoo ntev thiab kav ntev rau hnub ci cable tuam txhab thiab cov neeg siv tib yam nkaus. Qhov kev ua haujlwm ntev thiab kev saib xyuas me me yuav tsum tau txo tus nqi ntawm cov tswv cuab ntawm cov cable.
4. Sib piv nrog lwm tusHnub ci cables
Thaum muab piv nrog lwm lub hnub ci cirles, xws li h1z2z {2}} bables lossis PV1 cable los yog pv1 cable sawv tawm rau lawv cov khoom siv hluav taws xob thiab tshuab.
H1Z2Z {{{2} K Cleshy-} Cov qauv kev nyab xeeb, suav nrog cov khoom siv rwb thaiv tsev ntau dua, suav nrog cov khoom siv hluav taws xob tsis kam ua kom zoo dua qub. Lawv feem ntau siv nyob rau hauv ntau xav tau kev lag luam lossis kev lag luam hnub ci.
PV1 Cables yog tus qauv xaiv rau hnub ci kev siv thiab feem ntau siv pvc (polyvinyl chloride) raws li rwb thaiv tsev. Thaum pvc muaj nqi ntau dua, nws yog feem ntau tsawg dua ruaj khov thiab tiv taus UV teeb thiab huab cua sov ntau piv rau XLPE.
