Nyob rau hauv cov ntsiab lus ntawm hnub ci clesles thiab hnub ci xov hlau, ib qho ntawm cov khoom tseem ceeb rau koj lub zog hluav taws xob yog qhov kev ua haujlwm ntau. Lub PV 1- fable, uas yog siv nyob rau hauv photovoltaic (hnub ci zoo, muaj qhov ua tau zoo ntawm qhov kev ua haujlwm, muaj kev nyab xeeb nyob rau hauv ntau puag ncig. To taub cov parameter no yog qhov tseem ceeb los ua kom lub hnub ci ci tuaj yeem daws cov kev cov nyom ib puag ncig thiab kev coj ua lag luam hnub ci teeb tsa.
Kab lus no yuav tshawb txog kev ua haujlwm ntawm qhov kub ntawm PV {{m
1. Txheej txheem cej luam ntawmPV 1- f Cable
Ua ntej sib tham txog qhov kev ua haujlwm ntawm qhov kub, nws yog ib qho tseem ceeb kom xub nkag siab dab tsi ntawm PV 1-}} fable yog nyob rau hauv lub hnub ci zog.
Lub PV 1- f Cable yog ib hom daus tshwj xeeb tsim los siv hauv photovoltaic (hnub ci). Nws yog feem ntau siv los txuas cov vaj huam sib luag tog rau lwm qhov system xws li inverers, roj teeb cia tshuab, thiab cov tswj hwm roj teeb. Lub cable yog tsim los tiv thaiv sab nraud sab nraum zoov, raws li lub hnub ci hluav taws xob feem ntau lawv nthuav tawm ntau qhov chaw ib puag ncig, suav nrog kev sib txawv, tshav ntuj, thiab noo noo.
Lub PV 1- f Cable Nta:
Kev Ntsuas Hluav Taws Xob: Feem ntau ntsuas rau 1, 000 v dc.
Yam ruaj khov: Ua kom kawg nyob rau hauv cov xwm txheej hnyav, suav nrog UV siab raug thiab kev ntxhov siab.
Kev rwb thaiv tsev: Ua nrog tus ntoo khaub lig-txuas Polyethylene (XLPE) lossis lwm cov ntaub ntawv ruaj khov tsim kom muaj kev tiv thaiv ntau zaus thiab tiv thaiv ib puag ncig.
Nrog cov nta no, PV {{{{1- f Cables yog qhov zoo tagnrho uas kev ntseeg tau thiab kev nyab xeeb thiab kev nyab xeeb.
2. Kev khiav hauj lwm kub ntau yam ntawmPV 1- f Cable
Kev ua haujlwm ntawm qhov kub ntawm lub PV {{0} f cable uas muaj kev nyab xeeb uas tsis muaj kev nyuaj siab ntawm nws cov khoom siv hluav taws xob thiab tshuab. Rau lub PV {{1} fable, qhov kev ua haujlwm kub ntau yog feem ntau {2}} degree rau {}} degree.
2.1 Tsawg kub (-40 degree)
Ntawm qhov qis kawg ntawm qhov ntsuas kub ntawm -40 degree, lub pv {{1} f Cable tuaj yeem ua haujlwm tsis muaj nuj nqi yam tsis muaj teeb meem. Lub peev xwm no yog qhov tseem ceeb rau cov cheeb tsam nrog huab cua txias, qhov twg lub cable tej zaum yuav nthuav tawm khov kho lub caij ntuj no. Lub hnub ci cable yog tsim los ua kom yoog tau thiab muaj nuj nqi txawm tias muaj tsawg zaus kub, kom ntseeg tau tias hnub ci nruab hnub ua haujlwm.
Nyob rau hauv ib puag ncig txias, nws yog ib qho tseem ceeb kom paub meej tias lub cable tsis raug rau kev ntxhov siab lossis khoov thaum ntsuas kub yog qhov tsis tshua muaj. Txawm li cas los xij, nyob rau hauv cov qauv kev ua haujlwm, lub PV 1- f Cable yuav ua tsis muaj teeb meem ntawm qhov kub uas muaj tsawg li {1}} degree.
2.2 Kev kub siab (+90 degree)
Nyob rau qhov siab kawg ntawm qhov ntsuas kub, lub PV 1- fable tuaj yeem muaj kev ruaj ntseg ntawm {{1} degree. Qhov no muaj txiaj ntsig zoo tshwj xeeb rau cov huab cua nrog huab cua sov, qhov hnub ci yuav muaj kev kub ntxhov ntawm lub hnub thiab huab cua sov siab.
Qhov kev ntsuas kub siab kom ua kom muaj zog uas lub hnub ci cable tuaj yeem tiv thaiv cov pa hluav taws xob, nrog rau cov khoom siv ib puag ncig uas cov xaim hluav taws xob. Qhov no ua rau lub PV 1- f cable haum rau siv nyob rau hauv ntau thaj chaw thaj tsam, suav nrog cov chaw muaj lub hnub ci ntsa iab thiab kub.
Nws yog tsim nyog sau cia uas nyob rau qhov kub, lub cable rwb thaiv tsev yuav tsum muaj peev xwm tiv taus kev ua tsis taus kev ua haujlwm. The cross-linked polyethylene (XLPE) insulation used in the PV1-F cable is specifically chosen for its high thermal stability, which prevents it from becoming brittle or degrading at elevated temperatures.
3. Vim li cas qhov kev ua haujlwm yog qhov tseem ceeb?
TusKev Ua Haujlwm Qhov Kubntawm aHnub Ci Cableyog qhov tseem ceeb rau ntau yam:
3.1 Cable Distability thiab Kev Nyab Xeeb
Lub peev xwm ntawm lub hnub ci ntsa iab kom tiv thaiv huab ua rau muaj kev cuam tshuam loj ncaj qha rau cov kev ruaj khov thiab kev nyab xeeb ntawm tag nrho lub hnub ci zog. Yog tias qhov ntsuas kub tshaj lub cable tau teev tseg, cov rwb thaiv tsev lossis tus thawj coj tuaj yeem ua rau muaj kev phom sij hauv luv, lossis lwm yam kev cuam tshuam hluav taws xob. Qhov kev ua haujlwm ntau qhov kub ntau qhov kev ntseeg tau tias lub PV 1- f cable yuav ua haujlwm ncaj qha rau hauv cov hav zoov los, los ntawm cov hav zoov daus kom mus rau ib puag ncig daus.
3.2 Kev tiv thaiv ntawm cable kev puas tsuaj
Huab cua sov tuaj yeem ua rau muaj ntau hom kev puas tsuaj ntawm cable, xws li:
Brittleness: Hauv qhov kub txias, cov ntaub ntawv rwb thaiv tsev tuaj yeem ua tau tawg thiab tawg, ua rau muaj peev xwm kis tau tus cwj pwm.
Softening lossis melting: Nyob rau hauv cov chaw kub, rwb thaiv tsev cov ntaub ntawv yuav mos lossis yaj, uas yuav cuam tshuam rau cable lossis ntau dua. Los ntawm kev xaiv lub hnub ci cable nrog ib qho tsim nyog ua haujlwm kub ntau, koj tuaj yeem tawm tsam cov khoom ntawm kev puas tsuaj thiab txuas ntxiv ua haujlwm tau zoo.
3.3 Kev ua tau zoo thiab ua tau zoo
Lub PV 1- fable yog tsim los tswj nws cov hluav taws xob nyob thoob plaws hauv ntau qhov kub. Qhov no yog qhov tseem ceeb rau hnub ci zog vim tias kev hloov pauv hauv qhov kub tuaj yeem cuam tshuam rau kev ua tau hluav taws xob ntawm tag nrho cov kab ke. Yog hais tias cov xaim hluav taws xob raug rau huab cua sov dhau los ntawm lawv cov kev ua haujlwm, cov hluav taws xob poob qis, nqa khoom tam sim no, thiab tag nrho cov kev ua tau zoo, thiab tag nrho cov kev ua tau zoo, thiab tag nrho cov kev ua tau zoo, thiab tag nrho cov kev ua tau zoo, thiab tag nrho cov kev ua tau zoo, thiab tag nrho cov kev ua tau zoo, thiab tag nrho cov kev ua tau zoo, Ib qho tsim nyog ua haujlwm zoo ntsuas kub ntau yam kev ua tau zoo thiab kev tsim hluav taws xob ntawm koj lub hnub ci array.
4. Kev sib piv nrog lwm cov nplhaib ci ntsa iab
Lub PV 1- fable yog ib hom hnub ci cable, thiab muaj lwm cov xov hluav taws xob nrog cov kub sib txawv. Cia muab piv rau qhov kev ua haujlwm kub ntawm lub PV {{1} fable nrog lwm lub hnub ci nrov siv nyob rau hauv photovoltaic, xws li h1z2z {4 k cable thiab pv2 cable.
4.1 H1Z2Z 2- kable
H1Z2Z {{2- kable yog lwm tus siv hnub ci hauv photovoltaic, tshwj xeeb tshaj yog nyob rau hauv qhov loj dua, qib siab-hluav taws xob. Kev ua haujlwm ntawm qhov kub ntawm H1Z2Z {6}} k Cable yog zoo ib yam li pv -40 degree rau {{9} degree. Qhov no ua rau ob leeg hais kom haum rau kev siv hauv huab cua huab.
4.2 PV2 Cable
Lub PV2 cable feem ntau muaj kev ua haujlwm me ntsis ntau dua li ntau ntau, feem ntau rated nruab nrab ntawm {} {2}} degree. Qhov no ua rau PV2 cab ntau haum rau cov chaw ib puag ncig uas cov cable tej zaum yuav raug rau qhov siab dua lossis qhov uas muaj qhov xav tau ntau dua rau kev ruaj khov. Nws tseem zoo tagnrho rau cov kev ua siab zoo rau cov kev ua siab zoo uas qhov twg kub hloov tau ntau dua.
4.3 Piv thiab haum xeeb
Ob lub PV 1- f Cable thiab H1z2Z {3}} k Cable} k Cable} k Cable} Txawm li cas los xij, yog tias koj lub kaw lus nyob rau hauv ib cheeb tsam uas muaj qhov kub tshaj, koj yuav xav xav txog PV2 cable ntau dua, uas muaj qhov siab tshaj plaws kub siab txog kev ua siab ntev ntawm +120 degree.
5. Yuav Ua Li Cas Xaiv Lub Hnub Ci Cable raws li kev ua haujlwm kub
Thaum xaiv lub hnub ci ntsa iab rau koj lub kaw lus, nws yog ib qho tseem ceeb uas yuav tsum xav txog qhov kev ua haujlwm ntawm qhov ntsuas kub raws li ib puag ncig ib puag ncig ntawm koj qhov chaw nyob.
5.1 Xav txog koj txoj kev nyab xeeb hauv zos
Yog tias koj nyob hauv ib thaj av uas muaj qhov kub siab heev lossis qis qis, nws yog ib qho tseem ceeb kom xaiv lub hnub ci ci uas tuaj yeem ua cov mob no. Piv txwv li:
Hauv cov huab cua txias, qhov twg kub tsis tu ncua hauv qab -40 degree, lub pv {} f Cable yog haum rau cov ntawv thov hauv chaw nyob. Txawm li cas los xij, nco ntsoov daws cov cable kom zoo thaum lub teeb tsa kom tsis txhob muaj rwb thaiv tsev ya.
Nyob rau hauv cov huab cua kub kub, qhov twg kub tuaj yeem tshaj +90 degree, koj yuav txiav txim siab xaiv ib lub pv2 cable ntau tshaj qhov ntsuas kub ntawm {2}} degree.
5.2 Muab kev teeb tsa nyob rau hauv ib puag ncig heev
Nyob rau hauv ib cheeb tsam uas huab cua hlob heev, xws li cov roob havatus, ua kom koj lub hnub ci hnyav tsis yog, noo noo tsis kam, thiab lub zog siv zog. Qhov no yuav xyuas kom cov cable ua kom ntseeg tau raws sijhawm.
5.3 Cable ntev thiab voltage poob
Rau ntev cable khiav, qhov kub hloov pauv tuaj yeem ua rau voltage dauv thiab ua haujlwm poob ua tau zoo. Nco ntsoov tias lub hnub ci hlau yog tsim nyog rau cov kub thiab ntev xav tau los ntawm koj kev teeb tsa.
