Raws li ib qho tseem ceeb ntawm tag nrho cov chaw nres tsheb fais fab, lub hnub ci inverter yog siv los kuaj DC Cheebtsam thiab cov phiaj xwm sib txuas. Yeej, tag nrho cov chaw nres tsheb fais fab yuav raug kuaj pom los ntawm tusHnub ci InverterCov. Yog tias ib qho kev txawv txav, kev noj qab haus huv ntawm chaw nres tsheb cov cuab yeej txhawb nqa tuaj yeem tshawb xyuas los ntawm cov ntaub ntawv pub rov qab los ntawm lub hnub ci inverter. Hauv qab no yog cov ntsiab lus ntawm qee cov ntaub ntawv ua txhaum thiab kev kho cov qauv rau photovoltaic hnub ci inverters.
Tsis muaj cov ntsiab lus sib txuas
Ua rau ntawm qhov teeb meem:
Nws txhais tau tias AC fais fab tsis txuas nrog lossis AC Circuit Court breaker yog disconnected, ua rau muajHnub ci Inverteryuav tsis muaj peev xwm kuaj pom AC fais fab voltage.
Kev daws:
1. Txiav txim siab seb lub zog fais fab yog tawm ntawm lub hwj chim. Yog tias muaj, tos rau lub hwj chim sib tw los rov pib siv fais fab.
2. Yog tias lub zog hluav taws xob los ntawm lub zog hluav taws xob yog ib txwm, siv AC Voltage ntau ntawm cov kev ntsuas ntau ntau yam ntawm cov zis hluav taws xob yog ib txwm muaj. Ua ntej tshaj, ntsuas lub hnub ci inverter tso zis chaw nres nkoj thiab tshawb xyuas seb puas muaj teeb meem ntawm cov zis sab hauv lub hnub ci hauv. Yog tias tsis muaj teeb meem, nws txhais tau tias muaj kev sib tw puag ncig ntawm sab nraud AC sab. Koj yuav tsum tau tshuaj xyuas seb huab cua hloov, dhau-voltage thiab under-voltage tiv thaiv thiab lwm yam kev nyab xeeb hloov chaw puas tsuaj lossis qhib Circuit Court lossis qhib Circuit Court.
Ac voltage tawm ntawm ntau yam
Ua rau ntawm qhov teeb meem:
Thaum photovoltaic tiam tau txuas nrog tus neeg siv khoom siv sab sib chaws, tus voltage ntawm kev nkag mus rau kev nkag mus. Qhov ntau dua ntawm kev tawm tsam sab hauv ntawm lub hwj huam fais fab, muaj ntau dua qhov kev txaus siab no. Qhov ze dua rau cov hloov pauv, cov kab tsawg dua, cov kev hloov pauv me me hauv daim phiaj, thiab cov kab sib ze dua, thiab cov kab hluav taws xob ntev dua. Yog li ntawd, thaum lubHnub ci Invertertau txuas nrog cov kab sib txuas mus deb ntawm cov hloov pauv, cov phiaj chaw ua haujlwm ib puag ncig ntawm lub hnub ci inverter yuav ua rau tsis zoo heev. Tom qab cov kev txwv sab sauv ntawm lub hnub ci inverter ua haujlwm voltage tau tshaj, lub hnub ci inverter yuav qhia qhov txhaum thiab tsum tsis ua haujlwm. Raws li cov txuj ci kev paub rau photovoltaic lub zog tiam sib xyaw (Nb / t 32 ustomage Muaj kev nthuav dav hluav taws xob ntawm cov kab sib chaws, lub hnub ci inverter yog tso cai rau kaw. Tig rau lub zog hluav taws xob rau lub hwj huam sib tham thiab xa tawm cov teeb liab ceeb toom thaum nws txiav tawm. Lub hnub ci inverter yuav tsum muaj peev xwm pib thiab ua haujlwm ib txwm thaum cov grid voltage rov qab mus rau cov voltage pub dawb.
Kev daws:
1. Sim tso rau qhov chaw nkag ntawm lub chaw nres tsheb fais fab uas ze rau cov zis kawg ntawm lub transformer kom txo txoj kab poob.
2. Sim ua kom luv rau txoj kab ntev ntawm lub hnub ci inverter ac outpet core core coreter sib txawv ntawm lub hnub ci inverter thiab kab sib chaws.
3. Tam sim no feem ntau cov kab sib tw-cob qhia hnub ci invoters muaj AC qhov kev tswj hwm muaj nuj nqi. Koj tuaj yeem tiv tauj cov chaw tsim khoom lag luam kom dav AC Voltage tau ntau yam kom Haum rau Daim Phiaj Voltage Escteruesations.
4. Yog tias ua tau, cov zis hluav taws xob ntawm lub transformer tuaj yeem raug txo qis.
Tsawg rwb thaiv tsev tsis kam
Ua rau ntawm qhov teeb meem:
Lub hnub ci inverter muaj cov haujlwm ntawm kev ntes cov rwb thaiv tsev impedance ntawm DC sab. Thaum nws pom tias DC qhov ua tau zoo thiab tsis zoo rau hauv av yog qis dua 50Kω, lub hnub ci inverter yuav hais tawm ntawm tib neeg lub cev los ntawm kov lub neej ntawm lub vaj huam sib luag thiab hauv av ntawm Tib lub sijhawm, ua rau muaj kev pheej hmoo ntawm hluav taws xob hluav taws xob. Caw cov ntsiab lus muaj xws li: DC tivthaiv touchage; cable rwb thaiv tsev puas tsuaj, nyob rau thaj tsam ntawm kev ya raws; Cheebtsam bracket hluav taws xob yog neeg pluag; Huab cua thiab hluav taws xob chaw nres tsheb ib puag ncig cov av noo yog qhov siab dhau, thiab lwm yam.
Kev daws:
Disconnect cov pob AC thiab DC Cov Hluav Taws Xob Circuit Court, siv txoj hlua khi thiab tsis zoo ntawm cov kab ntawv DC kom ntseeg tau tias qhov ntau ntawm cov kab mob DC, txuas cov kev ntsuas liab ua rau qhov zoo tus ncej ntawm txoj hlua, thiab qhov kev ntsuas dub ua rau hauv av, nyeem cov ncej tus zoo rau hauv av, thiab tom qab ntawd nyeem cov kab mob tsis zoo ntawm txhua qhov tsis zoo Ncej rau hauv av. Yog tias nws yog tus loj dua 50Kω, nws yog kev txiav txim siab tias txoj hlua rwb thaiv tsev yog txhim khu kev qha. Yog tias nws tsawg dua lossis sib npaug, nws yog txiav txim tias muaj teeb meem nrog txoj hlua rwb thaiv tsev. Koj tuaj yeem tshawb xyuas cov kab mob cable ntawm txoj hlua cais kom pom tias muaj kev puas tsuaj lossis kev sib tiv tauj tsis zoo. Cov rwb thaiv hluav taws xob qis feem ntau txhais tau tias qhov zoo thiab tsis zoo cov qauv yog luv-ci ntsa iab rau hauv av.
To tam sim no yog dhau lawm
Ua rau ntawm qhov teeb meem:
Lub hnub ci inverter toppage tam sim no nrhiav tau cov module kuaj pom tias cov xau dej tseem ceeb heev. Txhawm rau tiv thaiv kev nyab xeeb ntawm tus kheej, nws tsis ua haujlwm thiab ceeb toom rau cov ntaub ntawv txhaum.
Kev daws:
1. Disconnect PV cov tswv yim, rov pib lub tshuab, thiab saib seb puas muaj lub tshuab tuaj yeem rov qab mus rau qhov qub.
2. Check whether the AC ground wire is connected to the live wire, measure whether the voltage between the ground wire and the live wire is normal, or use a leakage current detector to detect it.
3. Yog tias tsis muaj kev sib txuas ntawm cov xaim xaim hauv av thiab cov xaim hluav taws xob, nws yuav zoo li lub tshuab ua lag luam, thiab koj yuav tsum hu rau cov chaw tsim khoom kom pab.
DC voltage yog ntau dhau
Ua rau ntawm qhov teeb meem:
Muaj ntau cov txheej txheem sib txuas hauv ib txoj hlua PV, ua rau cov hluav taws xob ntau dua li ntau dua ntawm lub Voltage surlus ntawm lub hnub ci inverter.
Kev daws:
Txheeb xyuas cov lus ntawm lub hnub ci inverter, txiav txim siab DC voltage cov kev tawm tswv yim ntau, thiab tom qab ntawd kuaj xyuas seb puas muaj ntau yam uas muaj ntau ntawm cov hnub ci hauv inverter. Yog tias nws tshaj li qhov muaj txiaj ntsig zoo, txo cov naj npawb ntawm cov txheej txheem hauv txoj hlua.
Nyob rau hauv tib txoj kev, yog tias lub PV voltage yog qhia kom tsawg dhau, lossis cov qauv zoo thiab tsis zoo tau txuas, lub terminals yog xoob, hu yog neeg pluag, lossis txoj hlua qhib.
Tsis muaj ib qho tsis muaj zaub rau hnub ci inverter screen
Ua rau ntawm qhov teeb meem:
1. Tsis muaj DC cov lus qhia lossis lub zog siv hluav taws xob tsis ua haujlwm, lub hnub ci inverter LCD tau siv hluav taws xob tsis tuaj yeem ncav cuag lub hnub ci pib hluav taws xob.
2. Cov tswv yim PVinals tau txuas nrog reversely. Lub PV cov chaw muaj peev xwm muaj cov qauv zoo thiab tsis zoo, uas yuav tsum sib haum thiab tsis tuaj yeem txuas nrog hauv koob nrog lwm pab pawg.
3. Lub DC hloov tsis kaw.
4. Ib qho tivthaiv yog disconnected, ua rau lwm txoj hlua ua tsis tau haujlwm.
Kev daws:
1. Siv qhov ntau ntawm kev ntsuas cov DC cov tswv yim voltage ntawm lub hnub ci inverter. Thaum lub voltage yog li qub, tag nrho cov hluav taws xob yog cov lej ntawm cov hluav taws xob ntawm txhua qhov sib xyaw.
2. Yog tias tsis muaj voltage, xyuas seb qhov DC hloov, cov pob qij txha, cable pob qij txha, Cheebtsam, thiab lwm yam.
Kev soj ntsuam teeb meem
Ua rau ntawm qhov teeb meem:
Tus sau thiab hnub ci inverter tsis sib txuas lus; Tus collector tsis muaj zog rau: teeb meem teeb meem ntawm qhov chaw teeb tsa; sab hauv yog vim li cas ntawm tus collector.
Kev daws:
1. Txheeb xyuas qhov kev sib txuas lus sib txuas ntawm tus sau thiab covHnub ci Inverteryog ib txwm, thiab saib lub teeb sib txuas lus;
2. Tshawb xyuas lub teeb tsa lub zog hauv zos. Cov chaw uas muaj zog cov cim yuav tsum siv cov kav hlau txais xov tau zoo.
3. Scan tus lej collector kom raug
4. Thaum tsis muaj teeb meem nrog cov xwm txheej sab nraud, yog tias tus sau tsis teb rau txhua qhov kev sib txuas, nws tuaj yeem suav hais tias muaj kev ua tsis tiav ntawm tus sau.
Lub ntsiab
Saum toj no, cov teeb meem raug ntawmHnub ci Inverters Nyob rau hauv photovoltaic tau txheeb xyuas thiab qee cov lus qhia raug muab, tsom rau kev nkag siab txog qhov ua rau thiab kev kho mob ntawm cov teeb meem. Nyob rau tib lub sijhawm, nyob rau hauv txhua hnub ntawm kev saib xyuas cov chaw nres tsheb muaj zog, ua tiav kev nyab xeeb kev tiv thaiv kev nyab xeeb kev ntsuas thiab kev ua haujlwm zoo thiab kev txij nkawm yuav tsum muaj. Nws tseem yog tus yuam sij kom ntseeg tau cov nyiaj tau los ntawm chaw nres tsheb fais fab.
Raws li hnub ci inverter chaw tsim khoom nrog 12 lub xyoo ntawm kev txawj ntse, amensolar muaj 24/7 tom qab muag cov kev pab cuam los koom nrog peb cov network thiab loj hlob ua ke.
