Kev saib xyuas kev nyab xeeb thiab kev ua tau zoo: ib phau ntawv qhia rau DC-sab kev twb kev txuas nrog cov xov xwm hauv tsev hluav taws xob kev cia Inverters

Raws li tsev neeg lub zog khaws cia ua kom nrov, kom ntseeg tau kev nyab xeeb thiab ua haujlwm ntawm lawv cov hlau, tshwj xeeb ntawm DC-sab, yog qhov tseem ceeb. Qhov ncaj qha tam sim no (DC) kev sib txuas ntawm lub hnub ci ci, roj teeb, thiab inverers yog qhov tseem ceeb rau kev hloov hluav taws xob hnub ci thiab khaws cia zoo. Cov lus qhia no muab cov kev txiav txim siab ntawm cov kev txiav txim siab tseem ceeb, kev coj ua tau zoo tshaj plaws, thiab kev tswj hwm DC-sab kev twb kev txuas nrog cov hluav taws xob kev cia khoom siv hluav taws xob.

To taub txog sab hauv tsev neeg lub zog hluav taws xob cia khoom siv

DC-sab ntawm lub zog cia inverter yog qhov hluav taws xob tam sim no nyob nruab nrab ntawm lub hnub ci ua ntej hloov pauv mus ua lwm yam tam sim no (AC) rau kev siv tsev neeg. Sab ntawm lub kaw lus yog qhov tseem ceeb vim tias txhais ncaj qha rau lub zog ncaj ncees thiab kev cia khoom.

Hauv qhov qub hnub ci zog teeb tsa, lub hnub ci ntsa iab tsim cov hluav taws xob hluav taws xob, uas taug kev los ntawm cov roj ntsha kom them roj teeb. Lub zog khaws cia hauv cov roj teeb tseem yog hauv DC daim. Lub inverter ces converts no cov hluav taws xob ntim cia rau AC fais fab kom cov khoom siv hauv tsev.

Qhov tseem ceeb ntawm DC-sab suav nrog:

Hnub ci PV cables uas thauj hluav taws xob los ntawm cov vaj huam sib luag mus rau inverter thiab roj teeb.
Connectors uas txuas cov kab ke thiab cov khoom siv, ua kom muaj zog hloov hluav taws xob.
Fuses thiab hloov dua tshiab rau kev nyab xeeb, tswj thiab txiav tawm disconecting zog raws li xav tau.

Kev txiav txim siab muaj kev nyab xeeb tseem ceeb rau DC-sab xaim

Kev ntsuas kev nyab xeeb rau kev nyab xeeb rau DC-sab kev twb kev txuas nrog kev sib raug zoo los tiv thaiv cov hluav taws xob muaj kev phom sij thiab ua kom muaj kev ua haujlwm ntev. Ntawm no yog qee qhov tseem ceeb ua kom nco ntsoov:

Cable rwb thaiv tsev thiab sizing: Siv cov cable nrog cov rwb thaiv tsev kom tsim nyog tiv thaiv hluav taws xob xau thiab txo txoj kev pheej hmoo ntawm cov kab mob luv luv. Cable SIZING YUAV TSUM UA SI TAS NRHO TUB TAWM LOS RAU KEV TXHAJ TAWM THIAB Voltage tee, uas tuaj yeem tsim kev puas tsuaj thiab ua rau puas.

Yog lawm polarity: hauv DC tshuab, thim rov qab polarity tuaj yeem ua rau cov khoom tsis ua haujlwm lossis kev puas tsuaj. Ua kom pom tseeb cov kev sib txuas hlau yog qhov tseem ceeb kom tsis txhob muaj kev nyuaj siab.

Kev tiv thaiv dhau los: overcurrent tuaj yeem ua rau cov hluav taws xob rhiab thiab ua rau hluav taws. Tiv thaiv lub system los ntawm kev siv Fuses thiab Circuit Court cov foob uas phim qhov kev ntws tam sim no hauv kev xaij.

Kev cog lus: ua kom ua tau zoo kom txhua qhov tam sim no yog kev ncaj ncees rau hauv lub ntiaj teb, txo txoj kev pheej hmoo ntawm hluav taws xob thiab tswj hluav taws xob kom ruaj khov. Qhov av uas yuav tsum sib txawv los ntawm lub tebchaws tab sis yuav tsum nco ntsoov ua raws li nruj me ntsis.

Cov Khoom Siv CABLE siv rau DC-sab kev sib txuas

Xaiv cov cles yog rau DC-sab kev sib txuas yog qhov tseem ceeb rau kev nyab xeeb thiab kev ua tau zoo. Qee hom hom muaj xws li:

Solar PV Cables (H1Z2Z2-K, UL ​​4703, TUV PV1-F)**: These cables are designed for outdoor use and are resistant to UV radiation, high temperatures, and environmental stress. Lawv muaj cov qib siab ntawm kev hloov pauv, ua rau lawv zoo tshaj rau lub nruab hnub ci zog.

Kev kub siab ua kom ntev: DC-sab cables yuav tsum muaj peev xwm tiv thaiv hluav taws xob ntau los ntawm cov hluav taws xob tas li los ntawm lub hnub qub, tshwj xeeb tshaj yog thaum lub sijhawm ua haujlwm siab.

Ntawv pov thawj zoo: siv cov ntawv pov thawj ua raws cai ua raws li cov qauv kev nyab xeeb thiab pab tiv thaiv cov txheej txheem tsis ua haujlwm. Ib txwm xaiv cov kab ke uas tau raws li IEC, TUV, lossis UP qauv.

Cov Kev Ua Zoo Tshaj Plaws rau Kev Txhim Kho DC-Sab Hlau

Txhawm rau kom muaj kev nyab xeeb thiab kev ntseeg tau hauv DC-sab kev teeb tsa, ua raws cov kev coj ua zoo tshaj plaws:

Kev ncig cable: Kev ntsuas DC kom ruaj khov los txo cov huab cua huab cua thiab lub cev puas. Zam tsis txhob khoov, uas tuaj yeem ua rau cov xaim loj thiab ua rau sab hauv lub sijhawm.

Txo cov hluav taws xob hluav taws xob poob: Ua kom DC cables sai li sai tau sai li sai tau ua kom txo cov hluav taws xob hluav taws xob, uas tuaj yeem cuam tshuam kev ua haujlwm. Yog tias ncua deb yog zam tsis tau, nce cov cable loj kom them nyiaj.

Siv cov txuas tsim nyog: xyuas kom meej tias cov txuas yog huab cua thiab tau tshaj cov cable siv. Cov neeg tsis zoo sib txuas tau tuaj yeem ua rau lub zog tsis muaj zog lossis ua rau muaj kev pheej hmoo txaus ntshai.

Kev kuaj xyuas thiab kev saib xyuas tsis tu ncua: Tshawb xyuas DC wiring tsis tu ncua rau kev hnav thiab kua muag, suav nrog kev tawm dag zog, thiab kev sib txuas ntawm txoj kev xeb. Kev saib xyuas ib txwm tuaj yeem tiv thaiv cov teeb meem me los ntawm kev tig mus rau hauv cov teeb meem loj.

Cov kev ua yuam kev tsis raug rau hauv DC wiring

Txawm tias cov txheej txheem tsim tau zoo tuaj yeem ua tsis tau vim yooj yim yuam kev hauv cov txheej txheem teeb tsa. Tsis txhob muaj cov ntawv teev tseg no:

Undersized lossis cov cab tsawg: siv cov qoob loo uas me me rau lub kaw lus lub nra tam sim no tuaj yeem ua rau overheating, lub zog poob, thiab txawm tias hluav taws kub. Nco ntsoov xaiv cov kab ke uas tuaj yeem ua rau tag nrho cov hluav taws xob tawm ntawm koj lub kaw lus.

Kev tsis muaj kuab polarity: reversing polarity nyob rau hauv DC system tuaj yeem ua rau kev puas tsuaj rau cov khoom siv lossis ua tiav qhov system tsis ua haujlwm. Muab ob npaug rau kuaj sib txuas ua ntej ua kom muaj zog.

Kev ua haujlwm siab tshaj cables: Ntau tshaj xaim hluav taws xob tuaj yeem ua rau cables mus rau overheat. Xyuas kom muaj kev kaw lus zoo thiab dim pa, tshwj xeeb hauv cov chaw uas ntim nrog cov thawv tshuam.

Kev tsis saib xyuas cov lej hauv zos: txhua cheeb tsam muaj nws tus kheej hluav taws xob kev nyab xeeb, xws li nec hauv Asmeskas lossis IEC cov qauv thoob ntiaj teb. Ua raws li ua raws cov no tuaj yeem ua rau cov kab ke tsis ua haujlwm lossis teeb meem kev cai.

Ua raws li cov qauv thoob ntiaj teb thiab cov cai

Lub zog cia cov tshuab, suav nrog lawv cov xaim dc-sab, yuav tsum ua raws li ntau tus qauv hauv ntiaj teb no kom ntseeg tau tias muaj kev nyab xeeb thiab txhim khu kev qha:

IEC Cov Qauv: Lub Koom Haum Hluav Taws Xob Thoob Ntiaj Teb muab cov qauv qhia thoob ntiaj teb rau kev nyab xeeb hluav taws xob thiab kev ua tau zoo.

UL Cov Qauv: Underwriters Chaw Haujlwm (UL) yog dav siv nyob rau hauv North America, muab kev taw qhia txog kev nyab xeeb thiab ntawv pov thawj.

NEC (National Electrical Code): NEC muab cov cai thiab kev coj noj coj ua rau hluav taws xob daws teeb meem hauv Asmeskas. Ua raws li NEC cov lus qhia ua kom muaj kev nyab xeeb thiab ua raws.

Ua raws li cov qauv no tsis yog hais txog kev nyab xeeb xwb; Nws feem ntau qhov yuav tsum tau ua rau kev tuav pov hwm thiab tuaj yeem siv tau rau kev txhawb siab thiab rov ua haujlwm.

Saib xyuas thiab tswj cov kev sib txuas DC-sab

Txawm tias qhov zoo tshaj plaws-installed system yuav tsum tau soj ntsuam ib txwm thiab saib xyuas kom ua kom muaj kev ua tau zoo. Ntawm no yog yuav ua li cas nyob twj ywm:

Kev kuaj xyuas tsis tu ncua: Teem sijhawm kuaj xyuas cov tshev rau lub cev, hnav thiab kua muag thiab xoob sib txuas. Saib rau cov cim ntawm corrosion, tshwj xeeb yog nyob rau hauv chaw sab nraum zoov.

Kev soj ntsuam kev ua yeeb yam: Ntau lub inverters tuaj nrog ua rau cov neeg soj ntsuam uas tso cai rau cov neeg siv khoom los taug hluav taws xob kev tsim hluav taws xob thiab kev noj haus. Tshuaj xyuas cov cuab yeej tuaj yeem ceeb toom koj kom muaj teeb meem xws li kev npaj txhij txog lub zog, uas tuaj yeem teeb liab cov teeb meem hluav taws xob.

Kev hais cov teeb meem sai sai: Yog tias muaj qee cov cim ntawm kev hnav lossis kev puas tsuaj thaum pom kev tshuaj xyuas, kho lossis hloov cov ntu cuam tshuam tam sim ntawd. Kev nqis tes ua tau tuaj yeem tiv thaiv cov teeb meem me los ntawm kev nce mus rau hauv kev kho tus nqi me.
