Nyob rau hauv lub ntiaj teb ntawm lub hnub ci zog, xaiv ntawm txoj cai hnub ci sab yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab ua haujlwm. Ntawm cov cables muaj ntau, H1z2z {2}} k Cable sawv tawm raws li kev ntseeg siab thiab ruaj khov rau sab nraum zoov, tshwj xeeb hauv hnub ci hluavtaws. Kab lus no tsom rau cov neeg saib xyuas cov lus ntawm H1Z2z {5}} k cable thiab tshawb nws qhov tseem ceeb, thiab cov ntawv thov siv.
1. Nkag siab lubH1Z2Z 2- kable
Ua ntej poob siab rau cov tshwj xeeb ntawm cov neeg saib xyuas cov khoom, nws yog qhov tseem ceeb kom nkag siab dab tsi H1z2z {2}} k cable yog thiab vim li cas nws yog qhov xav tau rau hnub ci zog nruab.
H1Z2Z {{2- K Cable yog ib hom hnub ci cab siv rau siv hauv photovoltaic (hnub ci zog). Nws yog tus cwj pwm los ntawm nws qhov kev ntsuas siab siab siab, tiv taus UV hluav taws xob, thiab nws muaj peev xwm tiv taus kev tiv thaiv huab ib puag ncig. Cov cable no feem ntau siv los txuas cov panar ci ntsa iab rau inverers, nrog rau ntawm lwm qhov tseem ceeb hauv lub hnub ci system. Vim lawv cov kev nyab xeeb thiab kev nyab xeeb nta, H1Z2Z {5}} k Cables siv tau nyob rau hauv ob qho chaw thiab kev coj ua lag luam nruab hnub.
2. Cov khoom siv hauvHnub ci cables
Cov khoom siv ntawm lub hnub ci ntsa iab ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab nws cov hluav taws xob conduction, durability, thiab tag nrho cov kev ua tau zoo hauv lub hnub ci. Ob feem ob feem ntau siv cov neeg ua yeeb yam hauv hnub ci cables yog tooj liab thiab txhuas. Ob cov ntaub ntawv muaj lawv cov txiaj ntsig thiab cov tsis zoo, tab sis tooj liab tau pom tias yog qhov kev xaiv zoo tshaj plaws rau nws cov kev ntseeg tau zoo thiab ntev heev.
2.1 tooj liab thiab txhuas: ib qho kev sib piv
Tooj liab tau paub txog nws cov hluav taws xob conduction, uas tso cai rau nws nqa ntau tam sim no dhau mus nrog tsawg kawg nkaus nrog tsawg heev voltage poob. Tooj liab kuj muaj lub zog dua, ua rau lawv tiv thaiv lub cev thiab kua muag thiab kua muag tshwj xeeb hauv kev siv hluav taws xob sab nraum zoov.
Aluminium yog sib dua thiab feem ntau muaj nqi ntau dua li tooj liab, tab sis nws muaj qis dua. Qhov no txhais tau tias rau tib lub peev xwm tam sim no, tus thawj coj txhuas yuav tsum tau loj dua hauv tus neeg kos npe. Thaum txhuas tseem siv nyob rau hauv qee cov ntawv xov hluav taws xob, tooj liab tseem yog qhov kev xaiv uas xav tau zoo hauv kev ua haujlwm siab rau hnub ci.
Given the demanding nature of solar installations, which often involve high voltages and exposure to harsh environmental conditions, copper conductors are typically favored for solar cables like the H1Z2Z2-K cable.
3. Cov khoom siv ntawm H1z2z {2}} k cable
H1Z2Z 2- k cable nta tooj liab cigpors. Tooj liab tau dav tsam raws li cov khoom siv zoo rau hnub ci hlau daim ntawv thov vim muaj ntau yam:
Kev ua haujlwm siab: Tooj liab muaj qhov hluav taws xob zoo tshaj plaws, uas tso cai rau nws kom muaj zog hloov hluav taws xob rau lwm cov khoom siv hnub ci hauv lub tshuab hluav taws xob, xws li inverters lossis roj teeb. Nyob rau hauv lub hnub ci zog system, kev ua tau zoo ntawm lub zog kis ncaj ncaj ncaj ncaj tshwm sim ncaj qha rau lub zog tag nrho cov txiaj ntsig, ua tus tooj liab lub laj thawj.
Cov kev ua kom ruaj khov thiab xeb tsis kam: tooj yog tiv taus corrosion, tshwj xeeb tshaj yog thaum coated nrog qee yam khoom xws li tin lossis nyiaj. Qhov no ua rau tooj liab zoo tshaj plaws rau kev siv sab nraum zoov ntev ntev li cov hnub ci ib puag ncig xws li noo noo, UV hluav taws xob, thiab cov kev hloov pauv thiab kub. Sij hawm dhau los, txhuas cov cable tuaj yeem oxidize, ua rau kev tawm tsam kev tsim thiab ua rau muaj kev txhawj xeeb, tsis muaj tus tooj liab.
Mechanical zog: H1z2Z 2- k Cable yog tsim kom pom kev ruaj khov, thiab tooj txhua tus muaj peev xwm ntsib thaum lub sijhawm teeb tsa thiab tshaj lub neej ntawm lub system. Tooj liab kuj tsawg dua qub rau kev puas tsuaj los ntawm kev nthuav dav thiab kev txhawb nqa piv rau txhuas.
Yooj taus: cov neeg soj ntsuam tooj liab hauv H1z2z {2}} Kable hloov tau ntau dua li lawv cov tshuaj txhuas. Qhov kev hloov pauv tau no ua rau kev teeb tsa yooj yim dua, tshwj xeeb tshaj yog nyob rau hauv cov chaw kaw, thiab txo cov kev puas tsuaj vim yog khoov lossis sib ntswg.
Kev Ua Dej Kub Kub: Tooj liab tuaj yeem tiv taus cov dej khov ntau dua piv rau Aluminium yam tsis muaj kev cuam tshuam tseem ceeb. Qhov no tseem ceeb rau hnub ci hlau uas yuav tsum ua haujlwm nyob rau hauv cov kev mob ib puag ncig, suav nrog kev sim siab thaum muaj sijhawm nyob sab nraum zoov.
4. Vim li cas tooj liab yog qhov zoo rau hnub ci cables
Cov neeg xyuas cov khoom hauv cov txheej txheem hnub ci yuav tsum ua kom tau raws li cov kev cai hnub ci zog. Cov kab ke no feem ntau ua haujlwm nyob rau hauv ib puag ncig muaj chaw, nrog sab nraum zoov cov khoom plig nthuav tawm nthuav tawm rau cov khoom. Cables nyob rau hauv cov kab ke no yuav tsum tau muab cov khoom siv hluav taws xob txhim khu kev qha thaum ua kom muaj kev tawm tsam lub cev thiab ib puag ncig. Ntawm no yog vim li cas tooj liab yog qhov kev xaiv zoo tshaj plaws rau hnub ci cables zoo li H1z2z {2}} k:
4.1 Ua tau zoo tshaj plaws hauv cov hluav taws xob siab
Hnub ci system uas feem ntau ua haujlwm ntawm cov hluav taws xob siab, qee zaum tshaj li 1 kV dc. Tooj liab qhov muaj qis resistivity ua nws tus neeg coj zoo tshaj plaws rau cov ntawv thov siab tshiab. Nws kom ntseeg tau tias lub cable tuaj yeem ua kom muaj zog ntau ntawm hluav taws xob tsis muaj ntau dhau vim kev tsis kam, yog li kev txhim kho lub kaw lus tag nrho cov kev ua tau zoo tag nrho. Nyob rau hauv lub hnub ci zog system, txo lub zog poob yog qhov tseem ceeb rau kev ua kom tiav rov qab los ntawm kev nqis peev thiab ua kom cov kab ke ua rau lub zog siab tshaj plaws.
4.2 Lub sijhawm ntev
Lub hnub ci cable yuav tsum tau kawg rau tag nrho lub neej ntawm lub hnub ci zog, uas tuaj yeem tshaj 20-30 xyoo. Tooj liab yog inherently ntau ruaj khov thiab tiv taus kev ua tsis taus piv rau lwm cov ntaub ntawv. Thaum nthuav tawm cov ntsiab lus, tooj tus neeg uas tsis thuam tau sai li sai tau txhuas tus cwj pwm, ua kom muaj kev sib txuas ntev dua ntawm lub hnub ci.
H1Z2Z {{2- K Cable yog tsim los ntawm lub tsev neeg coj mus sab nraum zoov, thiab nws tus thawj coj tooj liab tsis tiv thaiv UV, ntau dhau, thiab noo noo. Qhov no ua rau nws zoo tagnrho cable rau sab nraum zoov lub zog nruab hnub ci nruab qhov chaw ib puag ncig tuaj yeem tsis tau.
4.3 Kev Nyab Xeeb thiab Kev Ua Haujlwm
Kev nyab xeeb yog qhov tseem ceeb tshaj plaws thaum tsim cov hluav taws xob hnub ci, uas yog cov xaim hluav taws tsis muaj peev xwm ua rau cov kab ke tsis ua lossis phom sij. Tooj liab lub siab ua kom tiav uas lub cable ua haujlwm tau zoo, tiv thaiv kev tiv thaiv dhau los yog lub zog los yog kev tsis kam. Qhov no txo qis kev pheej hmoo ntawm kev phom sij ntawm hluav taws, uas tuaj yeem tshwm sim yog tias ib qho cable ua kub heev vim qhov kis tau zoo. Tooj liab txoj kev nyab xeeb kev nyab xeeb ua rau nws xaiv lub hnub ci ua haujlwm, qhov twg hluav taws xob kev ua tau zoo thiab kev nyab xeeb yog qhov tseem ceeb.
5. Cov ntawv thov ntawm tooj liab-neeg coj h1z2z {3}} k cables hauv lub hnub ci
Tus txiv neej tooj ntawm H1z2z {2}} kable ua nws cov kev xaiv zoo thiab txhim khu kev qha rau hnub ci nruab. Hauv qab no yog qee qhov ntawm thawj cov ntawv thov ntawm cov kab no hauv kev lag luam lub zog hluav taws xob:
5.1 Vaj Huam Sib Luag rau Inverter sib txuas
H1Z2Z {{2- pam cable feem ntau siv los txuas rau hauv Inverter Cov Panels rau lwm cov khoom siv tam sim no (AC) lub zog rau kev siv hauv tsev lossis lag luam. Cov kev sib txuas no yuav tsum tau cables nrog cov kev ntsuas siab ntau thiab cov tsis tshua muaj zog kom ntseeg tau tias cov zog pauv tau zoo thiab nyab xeeb. Tus txiv neej tooj liab nyob hauv H1z2Z {5}} k muab cov khoom tsim nyog rau cov kev sib txuas tseem ceeb no.
5.2 hnub ci roj teeb cia tej tshuab
Rau cov nruab hnub ci uas suav nrog cov hluav taws xob cia, xws li roj teeb, H1Z2Z {2}}}}}}}}}}}}}}}} Cov qoob loo yuav tsum muaj peev xwm ua kom muaj peev xwm tuav cov dej khov thiab feem ntau, tshwj xeeb tshaj yog nyob rau hnub ci loj dua uas tau siv. Tooj liab cov neeg xyuas kom ntseeg tau tias lub zog pauv yam tsis muaj qhov poob qis lossis txaus ntshai.
5.3 Daim phiaj sib txuas
Rau cov tshuab uas txuas nrog cov kab sib chaws hluav taws xob, h1z2z 2- Kuv siv hluav taws xob los hloov hluav taws xob rau daim phiaj. Cov CABLES yuav tsum daws cov hwj chim loj thiab ua kom muaj txiaj ntsig kev sib kis nrog qhov tsis tshua muaj zog. Tooj liab lub siab ua kom nws cov khoom zoo tshaj plaws rau cov kev sib txuas siab.
