Nrog rau kev nce ntxiv rau lub zog txuas ntxiv thoob plaws ntiaj teb, Hnub ci photovoltaic (PV) cov tshuab tau dhau los ua cov tsev tseem ceeb rau ntau lub tsev thiab vaj tse. Thaum lub teeb tsa kev teeb tsa ntawm PV system, xaiv txoj cai cables (hnub ci cab) Kab lus no yuav tshawb txog ntau yam ntawm cov conduits siv hauv PV systems thiab yuav ua li cas lawv tiv thaiv lub hnub ci ci thiab xaim thaum lub teeb.
1. Cov kev xav tau rau cov xaim thiab xaim hauvPV tshuab
Hauv kev sib txuas hluav taws xob ntawm PV system, hnub ci cables thiab cov hlau ua rau cov tub ntxhais sib kis ntawm lub zog kis. Lawv xaiv ncaj qha cuam tshuam rau kev nyab xeeb, ua haujlwm thiab kev ntseeg tau ntawm cov kab ke. Piv nrog cov cable dog dig, PV cable feem ntau muaj cov yam ntxwv hauv qab no:
Kev kub siab kuj:Hnub ci cable feem ntau yog siv nyob rau hauv ib puag ncig sab nraum zoov thiab tej zaum yuav raug rau qhov kub thiab ultraviolet hluav taws xob yuav tsum muaj kub ua tsis kam thiab UV tsis kam.
High Voltage nqa muaj peev xwm:Niaj hnub PV lub tshuab niaj hnub feem ntau muaj kev ua haujlwm siab zoo nrog 600V, 100V, 100V, yog li 1500v, yog li hnub ci cables yuav tsum muaj peev xwm tiv taus ntau dua volfages.
Dej tsis kam thiab corrosion Kuj:Txij li cov kab ke feem ntau yog nthuav dav ib puag ncig huab cua thiab sab nraum zoov ib puag ncig, lub hnub ci yuav tsum muaj cov dej zoo thiab xeb tsis kam.
Neeg kho tshuab puas tsuaj kuj:Cov kab ke yuav raug kev txom nyem qee yam kev puas tsuaj lub cev thaum lub sij hawm teeb tsa, yog li lawv cov qauv yuav tsum muaj kev tiv thaiv thiab ntuag.
Qhov tseeb xaiv ntawm lub hnub ci cables thiab cov xov hlau tuaj yeem ua haujlwm ntev thiab ua haujlwm ntawm cov kab ke thiab kev nyab xeeb ntawm cov teeb meem hluav taws xob tshwm sim los ntawm cable kev puas tsuaj.
2. Lub luag haujlwm ntawm cov khoom ua hauv photovoltaic
Hauv photovoltaic, conduits yog cov khoom tseem ceeb siv los tiv thaiv solar cable thiab xov hlau. Cov haujlwm tseem ceeb ntawm cov conduits suav nrog:
Kev tiv thaiv lub cev:Conduits muab kev tiv thaiv lub cev rau cov kab kom tsis txhob muaj kev puas tsuaj rau cov qoob loo.
Tiv thaiv kom tsis txhob sab nraud:Conduits tuaj yeem tiv thaiv cov kab ke los ntawm cov hluav taws xob sab nraud xws li ultraviolet hluav taws xob, cov huab cua zoo nkauj (xws li cua daj cua dub, daus) thiab tsiaj tom.
Txhim kho hluav taws xob kev nyab xeeb:Conduits pab tiv thaiv kom tsis txhob muaj cov khoom siv hluav taws xob lossis cov chaw puag ncig, yog li txo qhov kev pheej hmoo ntawm hluav taws lossis hluav taws xob.
Yooj Yim Installation thiab Txij Nkawm:Conduits tuaj yeem npaj cov kev sib tw cable, txo cov cable entanglement thiab tsis meej pem, thiab pab txhawb kev soj ntsuam tom ntej thiab txij nkawm.
3. Tib hom conduit siv hauvTshuab photovoltaic
Hauv lub teeb tsa ntawm cov photovoltaic, cov qauv conduit ntau hom suav nrog cov khoom siv hlau, tsis yog hlau nplaum conduits, thiab hloov tau conduits thiab hloov tau conduits Txhua hom conduit muaj nws tus kheej cov yam ntxwv tshwj xeeb thiab kev thov sau cov xwm txheej. Xaiv hom conduit txoj cai tuaj yeem pab txhim kho kev nyab xeeb thiab kev ntseeg tau ntawm cov kab ke.
3.1 metallic conduits (xws li EMT thiab IMC)
Cov khoom siv metallic feem ntau siv hauv photovoltaic uas xav tau kev tiv thaiv kev siv lub cev, tshwj xeeb tshaj yog nyob hauv cov cheeb tsam uas muaj kev phom sij rau lub cev lossis muaj peev xwm txaus ntshai. Cov conduse no feem ntau yog ua los ntawm txhuas lossis hlau thiab muaj lub zog siab thiab lub zog.
EMT (Cov Hluav Taws Xob Cov Hlau Hlau Tubing):EMT yog ib lub teeb yuag sib zog hlau ua feem ntau siv rau kev tiv thaiv cable thiab sab nraum zoov ib puag ncig. EMT muaj qhov nruab nrab corrosion tsis kam, tab sis yog qhov haum rau cov chaw muaj zog lossis me. Nws yog qhov tsim nyog rau me me tam sim no thauj khoom thiab yooj yim rau nruab.
IMC (Intermediate Hlau Conduit):IMC muaj ntau dua emt thiab yog haum rau cable kev tiv thaiv nyob rau hauv ib puag ncig kev lag luam, tshwj xeeb yog cov xwm txheej sab nraum zoov. Nws muaj cov zoo corrosion tsis kam thiab kev sib deev tsis kam, thiab tuaj yeem tiv thaiv kev tiv thaiv lub cev rau hnub ci.
Qhov zoo ntawm cov hlau hlau yog lawv txoj kev tiv thaiv thiab muaj zog rau cov xaim xwm, thaum qhov kev teeb meem yog lawv cov txheej txheem teeb tsa yog qhov nyuaj thiab kim.
3.2 Tsis yog xim hlau conduits (xws li PVC conduits)
Cov khoom siv tsis yog metallic conduits yog cov feem ntau siv hom conduit hauv photovoltaic. Cov khoom siv uas tsis yog hlau nplaum cov ntaub ntawv suav nrog PVC (HDyvinyl chloride) thiab HDPE (High-ntom polyethylene), uas yog lub teeb nyob rau hauv qhov hnyav, tsawg tus nqi, thiab yooj yim rau nruab.
PVC Conduits (Polyvinyl Tshuaj Chloride):PVC Conduits muaj ntau heev spyovoltaic Cable tiv thaiv cov leeg thiab haum rau feem ntau cov photovoltaic installation nruab nrog. PVC conduits muaj zoo corrosion tsis kam, dej tsis kam, thiab UV kuj, thiab tuaj yeem ua haujlwm nyob rau hauv lub sijhawm ntev sab nraud. PVC Conduits yooj yim rau nruab thiab muaj tus nqi qis, yog li lawv tau siv dav hauv kev tiv thaiv ntawm photovoltaic cables.
HDPE conduits (High-ntom polyethylene conduits):HDPE conduits muaj cov tensile zoo dua thiab cuam tshuam rau kev siv cov xwm txheej loj, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov cov xwm txheej uas xav tau kev tiv thaiv tshuab lossis tshuab kev puas tsuaj. HDPE conduits kuj tseem hloov tau yooj yim thiab tuaj yeem tiv nrog cov xaim hluav taws xob.
Qhov zoo ntawm kev tsis yog xim hlau conduits yog lub teeb yuag, tus nqi qis thiab kev teeb tsa yooj yim. Qhov tsis zoo yog tias lawv lub cev muaj zog yog qhov tsis txaus siab rau qhov ntawd ntawm cov hlau hlau thiab lawv yooj yim cuam tshuam los ntawm huab cua sab nraud lossis huab cua sab nraud.
3.3 Condibible conduits (xws li FMC conduits)
Saj zawg zog cov conduits feem ntau yog siv hauv photovoltic cov tshuab uas yuav tsum tau khoov thiab hloov kho cov chaw uas muaj qhov chaw me me lossis cov cuab yeej siv tau tsiv mus ntau. Cov khoom siv ntawm cov khoom siv hloov tau feem ntau yog hlau lossis yas, muaj siab siab thiab kho tau.
FMC (hloov chaw ntawm nws yog xim hlau):FMC conduit yog ib qho yooj yim hlau conduit, feem ntau yog ua los ntawm cov hlau hlau zoo, haum rau ib puag ncig nrog cov chaw me me thiab txoj hlua hluav taws xob me me. Nws hloov tau yooj yim dua EMT thiab IMC thiab haum rau cov txheej txheem nyuaj.
LFMC (Ua kua-nruj hloov pauv ntawm nws yog xim hlau conduit):LFMC Conduit tau muaj zog dua dej tsis muaj zog dua FMC conduit thiab haum rau thaj chaw uas muaj kev tiv thaiv hnyav lossis kev tiv thaiv dej ntxiv. Nws yog qhov tsim nyog rau sab nraum zoov lossis sab nraum zoov ib puag ncig thiab muaj peev xwm tiv thaiv noo noo los ntawm kev nkag mus rau hauv kev conduit.
Qhov kom zoo dua ntawm kev hloov tau zoo yog lawv cov khoom yoog tau thiab hloov tau, tshwj xeeb hauv cov chaw uas nquag txav los yog muaj chaw nyob tsawg. Qhov tsis zoo yog tias lawv yog kim kim thiab me ntsis qis dua los ua kom nruj rau cov khoom ntawm kev tiv thaiv.
4. Lub hauv paus rau xaiv conduits
Thaum xaiv hom conduse hauv PV system, cov ntsiab lus tseem ceeb hauv qab no yuav tsum tau txiav txim siab:
4.1 ib puag ncig mob
Qhov kev xaiv ntawm cov conduits yuav tsum txiav txim siab raws li cov ncauj lus tshwj xeeb ntawm ib puag ncig kev teeb tsa. Rau PV tshuab uas yuav tsum tau siv nyob rau hauv ib puag ncig hnyav (xws li kub, muaj qhov muaj zog uve thiab corrosion tsis kam.
Kev Siv Sab Nraum:Txog sab nraum zoov, PVC thiab HDPE conduits yog cov kev xaiv muaj ntau, uas muaj UV tsis kam zoo.
Cov teeb meem hauv av:Rau kev tiv thaiv hauv av cable, hlau conduits lossis HDPE conduits feem ntau yog thawj qhov kev xaiv, uas tuaj yeem tiv thaiv lub siab thiab puas hauv cov chaw hauv av.
Ntub lossis hauv qab dej ib puag ncig:Yog tias lub cable xav tau kom raug cov dej lossis cov av noo, xaiv ua kua-nruj hloov cov qhab nia siv hluav taws xob nrog cov qib tsis muaj dej.
4.2 Kev Txhim Kho Kom Muaj
Chaw teeb tsa:Yog tias lub teeb tsa ib puag ncig ntawm PV system yog me me los yog lub cable xav tau los mus xaiv cov khoom siv yooj yim (xws li FMC).
Cable hom thiab Voltage theem:Rau PV tshuab nrog ntau dua voltage ntau ntau qib, hlau conduits xws li EMT lossis IMC tuaj yeem muab kev tiv thaiv lub cev muaj zog.
4.3 tus nqi thiab saib xyuas
Tus nqi: PVC Conduits feem ntau yog qhov kev xaiv tau zoo tshaj plaws, tshwj xeeb hauv tej yaam num nrog nyiaj txiag tsawg.
Tswj kom muaj:Saj zawg zog cov conduits muab ntau dua yooj thiab yooj yim yog tias cov xaim yuav tsum tau kuaj xyuas lossis tswj tau yav tom ntej.
