Hauv kev tsim qauv thiab teeb tsa ntawm lub hnub ci zog, kev tiv thaiv hluav taws xob tseem ceeb yog nthuav tawm ntau yam kev mob uas tuaj yeem ua rau muaj hluav taws xob ib puag ncig, lossis hluav taws kub. Ntawm cov ntau ntau hom hnub ci cables, lub pv 1- fable yog siv rau kev sib txuas hnub ci (PV) system. Ib qho ntawm cov tseem ceeb ntawm lub hnub ci dej zoo li PV {1}} f yog lawv cov kev tiv thaiv hluav taws, thiab txo qis hluav taws kub hauv lub system.
Hauv tsab xov xwm no, peb yuav tshawb txog kev tiv thaiv kev tiv thaiv hluav taws kub ntawm PV {{m
1. Dab tsi yog qhov kev tiv thaiv hluav taws kub ntawmPV 1- f Cable?
Lub PV 1- f Cable yog tsim los siv rau hauv kev tiv thaiv hnub ci, thiab nws qhov kev tiv thaiv hluav taws xob yog qhov tseem ceeb hauv kev nyab xeeb thiab ua raws li cov qauv kev nyab xeeb. Kev tiv thaiv hluav taws kub ntawm PV {1- f Cabulation yog feem ntau ntawm cov ntaub ntawv siv nyob rau hauv nws cov khoom siv rwb thaiv tsev yam tsis muaj kev pheej hmoo rau lub kaw lus lossis ib puag ncig ib puag ncig.
1.1 Cov Qauv Hluav Taws Xob Cov Qauv Rau Pv 1- f Cable
Kev tiv thaiv hluav taws kub ntawm PV {{{{{} f cabe yog feem ntau ua rau cov hluav taws xob rov qab, thiab cov pa hluav taws xob tsis kam siv hluav taws xob, suav nrog lub hnub ci.
Iec {60332-1: Tus qauv no txhais cov cai rau cov nplaim taws ntawm cables. Nws xeem yuav ua li cas cable teb rau lwm qhov chaw taws hluav taws. Cables uas xeem qhov kev xeem no tau faib ua nplaim retardant lossis cov pa hluav taws.
Iec {60754-1: Tus qauv no tsom rau cov pa roj roj roj ntxiv thaum lub sijhawm sib txuas. Cables nrog cov kua qaub cov kua qaub tsis tshua muaj kev nyab xeeb yog qhov muaj kev nyab xeeb thaum tua hluav taws, raws li lawv txo qhov kev pheej hmoo ntawm cov tshuaj lom neeg lom.
Iec {61034-2: Tus qauv no txhais cov pa luam yeeb ntom ntom ntawm cov cable thaum raug hluav taws. Lub PV 1- f C sim ua kom ntseeg tau tias nws yog qhov tseem ceeb tshaj plaws thaum muaj xwm txheej ceev thiab khiav tawm thaum muaj xwm txheej ceev.
Feem ntau PV {{{{{0} f Cables Ua kom ntseeg tau tias lawv tuaj yeem tiv thaiv ntau yam hluav taws kub thiab tiv thaiv kev kis hluav taws. Cov cable no feem ntau yog nplaim retardant thiab tau faib raws li lawv qhov kev ua tau zoo hauv kev kuaj hluav taws.
1.2 Nplaim Retardant Khoom
Lub PV 1- f Cable yog tsim nrog nplaim retardant sab nraud thiab rwb thaiv tsev cov nplaim taws. Cov khoom siv cable yog tsim los rau tus kheej-extinguish ib zaug ntawm qhov hluav taws kub tawm ntawm kev kis ntawm cov cable thiab txo cov hluav taws kub tag nrho hauv cov kab ke.
Cov nplaim taws-retardant cables zoo li PV {{1} f tau tsim los ua kom tau tsim los ua kom tau tsim los ua kom tau cov neeg IEC 60332, lub ntsiab lus uas lawv tuaj yeem ua rau lub sijhawm uas tsis muaj xwm txheej.
Tsawg cov pa taws xoom halogen (LSZH) versions ntawm PV {{f clesexic haus luam yeeb, uas yog qhov tseem ceeb hauv cov chaw nyob hauv qhov chaw kaw lossis cov tsev pej xeem.
Los ntawm ua raws cov qauv no, PV {{{1- f cleshes kev tiv thaiv, txo qhov kev pheej hmoo ntawm hluav taws xob kev puas tsuaj hauv lub hnub ci hluav taws xob.
2. Qhov tseem ceeb ntawm hluav taws kev tiv thaiv hauvHnub ci cables
Muab kev cog qoob loo ntawm lub hnub ci hauv thaj chaw, ua lag luam, thiab kev nyab xeeb ntawm hluav taws xob ntawm lub hnub ci kab yog qhov tseem ceeb tshaj plaws. Kev tiv thaiv hluav taws kub tiv thaiv cov xov hluav taws xob yog qhov tseem ceeb rau ntau yam:
2.1 Overheating thiab hluav taws hluav taws xob
Hnub ci cables yog lub luag haujlwm rau kev nqa hluav taws xob los ntawm lub hnub ci ci rau lwm cov system. Yog hais tias cov zaub dej yuav dhau los ua kev loj dhau los yog puas, lawv tuaj yeem tshaj, muaj peev xwm ua rau hluav taws hluav taws xob. Qhov kev pheej hmoo no yog qhov ua kom muaj kev sib txuas ntawm kev sib txuas tsis zoo, cov khoom sib txuas tsis raug, lossis cov khoom siv tsis raug. Lub PV 1- fable yog tsim los txo cov ntaub ntawv muaj kev phom sij nrog nws cov hluav taws xob yuav tsis yooj yim ntes hluav taws txawm tias muaj kev mob hnyav.
2.2 Kev tiv thaiv hluav taws kis
Kev tiv thaiv hluav taws kub ntawm lub hnub ci ntsa iab zoo li PV 1- f yog qhov tshwj xeeb tshaj yog kev tiv thaiv tus kab hluav taws rau cov ntaub ntawv uas muaj xws li cov ntaub ntawv uas muaj xws li cov ntaub ntawv. Hnub ci cables yog feem ntau ntsia nyob rau hauv ru tsev, attics, lossis lwm thaj chaw uas muaj cov ntaub ntawv uas muaj cov ntaub ntawv uas muaj cov ntaub ntawv sib txuas nyob ze. Yog tias hluav taws tau tawg tawm, cables nrog cov nplaim hluavtaws tsis muaj peev xwm pab tiv thaiv kom tsis txhob kis tau hluav taws xob tawm sai sai, muab sijhawm ntau rau cov neeg ntxiv rau cov neeg.
Lub PV 1- f cable cov nplaim hluav taws-retardant sheath ua kom cov nplaim taws uas tsis tau taug kev hauv tsev lossis cov khoom siv ntawm lub hnub ci. Qhov no yog qhov tseem ceeb tshaj plaws hauv kev txo qis kev pheej hmoo ntawm kev puas tsuaj rau hnub ci inverers, roj teeb, thiab lwm yam khoom siv rhiab.
2.3 Kev nyab xeeb rau cov neeg siv kawg
Kev nyab xeeb ntawm qhov kawg-cov neeg siv yog thawj qhov kev txhawj xeeb thaum xaiv lub hnub ci. Cables nrog cov hluav taws tsis zoo yuav ua rau muaj kev phom sij loj, suav nrog kev raug mob, khoom puas, lossis txawm poob lub neej. Los ntawm kev siv cables zoo li PV 1- f, uas yog tshwj xeeb tsim los ua kom haum rau hluav taws kub systemste muaj kev nyab xeeb thiab ua raws li cov cai hauv zos.
3. Piv ntawm PV 1- f Cable nrog lwm lub hnub ci ci
Thaum lub pv 1- f Cable yog qhov kev xaiv nrov rau ntau hnub ci ntsa iab, nws yog ib qho tseem ceeb rau hnub ci ntsa iab, nws yog ib lub hnub ci ntsa iab, nws yog kev tiv thaiv hluav taws xob, ua raws li kev tiv thaiv hluav taws.
3.1 H1Z2Z 2- kable
H1Z2Z {{2- k cable, feem ntau siv nyob rau hauv lub hnub ci hluav taws xob, tseem muab kev tiv thaiv hluav taws xob zoo vim nws cov begerylene (xlpe) rwb thaiv tsev thiab riam. Zoo li PV 1- f cables, h1z2z {} Kuv haum rau cov khoom hluav taws xob siab, ua rau cov khoom siv hluav taws xob sib xws, ua rau cov khoom lag luam zoo sib xws, kev lag luam hnub ci.
H1Z2Z {{2- Kable yuav muab cov hluav taws kub tiv thaiv cov hluav taws xob high yog khiav hauv cov cheeb tsam nrog kev pheej hmoo hluav taws kub ntxiv.
PV {1- f cablesyog cov haum rauCov Nruab Nrab Hnub Ci, qhov twgKev Tiv Thaiv Hluav TawsthiabYooj yim ntawm kev teeb tsayog cov kev txhawj xeeb tseem ceeb.
3.2 PV2 cables
PV2 cov xaim yog tsim los siv rau hauv high-volar hnub ci system, thiab lawv feem ntau tshwj xeeb cov ntaub ntawv hluav taws xob xws li LSZH (tsawg pa taws xoom Halogen) thiab XLPE. Lawv muaj cov qauv kev nyab xeeb xws li PV {}}} f cables, tab sis feem ntau siv rau cov nroj tsuag hluav taws xob loj dua lossis cov tshuab ua lag luam.
PV {{{1- f cables feem ntau yog hloov tau ntau dua thiab tuaj yeem siv cov kev tiv thaiv hluav taws kub thiab cov khoom lag luam me me.
PV2 cables, nrog lawv cov kev ntsuas hluav taws xob siab, tuaj yeem muaj hluav taws kub me dua vim tias qhov kev xav tau ntawm cov rwb thaiv tsev thiab nplaim hluav taws xob hauv cov tshuab loj.
4. Yuav ua li cas kom ntseeg tau tias hluav taws kub kev nyab xeeb nrog PV 1-} f cables
Txhawm rau kom muaj kev nyab xeeb ntawm hluav taws xob ntawm lub hnub ci zog siv siv PV {{} pib} f cables, nws yog ib qho tseem ceeb rau kev ua raws thiab cov txheej txheem saib xyuas kom zoo. Nov yog qee cov lus qhia tseem ceeb kom ua raws:
4.1 Tsim nyog Cable Installation
Nco ntsoov tias cov khoom siv hnub ci yeeb yaj kiab tau teeb tsa raws li cov khw cov lus qhia thiab ua raws li cov lej hluav taws xob.
Siv cov kev tiv thaiv cable uas tsim nyog, tshwj xeeb tshaj yog nyob hauv thaj chaw uas yuav ua rau muaj kev puas tsuaj rau lub cev, uas tuaj yeem ua rau muaj kev cuam tshuam txog hluav taws xob.
4.2 Kev kuaj xyuas ib txwm
Hnub ci yuav tsum tau tshuaj xyuas kom tsis tu ncua rau cov paib ntawm hnav thiab ntuag rau cov cables, tshwj xeeb tshaj yog cov kab hlau sab nraud. Saib rau cov nrib pleb, kev puas tsuaj, lossis tshem tawm uas yuav qhia kev puas tsuaj.
Ua cov cua sov ua kev tshuaj ntsuam xyuas kom paub cov khoom kub hauv qhov system, uas tuaj yeem ntsib lub peev xwm rau overheating.
4.3 Ua raws li cov kev cai nyab xeeb
Xaiv Solar cab zoo li PV 1- f uas ua raws thoob ntiaj teb kev nyab xeeb cov qauv kev nyab xeeb. Xyuas kom meej tias koj lub kaw lus tsim thiab teeb tsa kom tau raws li cov cai hauv nroog rau kev tiv thaiv hluav taws.
Hauv cheeb tsam nrog cov hluav taws kub siab dua, xav txog kev siv cov xaim hluav taws xob ntau dua nrog cov kab hluav taws xob ntxiv, xws li LSZH version ntawm PV {}} f cables.
