Qhov yuam kev 1: Tsis muaj DC Isolator - Los yog siv qhov pheej yig AC Hloov
Yuav ua li cas?
Tsis muaj DC hloov ntawm lub hnub ci vaj huam sib luag thiab lub inverter. Los yog nruab nrab ntawm lub roj teeb thiab lub inverter. Los yog ib tug neeg siv lub AC hloov pheej yig uas lawv tau pw ib puag ncig.
Thaum koj yuav tsum tau kho qhov system, koj tsis tuaj yeem tshem tawm yam xyuam xim. Qhov phem tshaj, DC tam sim no tsis muaj xoom hla. Nws tsim arcs ntau dua li AC. Ib tug pheej yig hloov yuav ua rau arcing thaum koj sim tua nws. Cov contacts hlawv. Lub arc txuas ntxiv mus. Hluav taws pib.
Yuav ua li cas kom raug:
| Qhov chaw | Yam koj xav tau |
|---|---|
| Hnub ci vaj huam sib luag → inverter / charger | DC isolator (DC ntsuas, tsis AC ntsuas) |
| Roj teeb → inverter | DC breaker lossis fuse + cais |
| Inverter → faib vaj huam sib luag | AC breaker |
Lub ntsiab lus tseem ceeb:Yuav ibDC - ntsuashloov. AC keyboards tsis tuaj yeem ua haujlwm. Lawv saib zoo ib yam. Internal arc suppression yog txawv kiag li.
Qhov yuam kev 2: Cov kab hluav taws xob tsis zoo - Qhov phom sij zais zais
Yuav ua li cas?
Txhawm rau txuag nyiaj, ib tus neeg siv cov cables nyias dua li qhov xav tau. Los yog lawv tsuas muaj nyias cable ntawm tes, yog li lawv siv nws.
Nyias cable muaj zog dua. Tam sim no ntws los ntawm nws. Nws kub. Ntau load txhais tau tias muaj cua sov ntau dua. Rwb thaiv tsev melts. Cov xov hlau zoo thiab tsis zoo luv luv tawm. Teeb. Hluav taws.
Qhov no tsis yog exaggeration. Peb pom qhov tseeb: tus neeg siv khoom siv 4mm² cable rau 2000W inverter. Tom qab 30 feeb ntawm tag nrho cov load, lub cable hloov mus rau hauv ib tug cua sov hlau thiab melted txhua txhua hlau nyob ib ncig ntawm nws.
Yuav ua li cas kom raug:
| Inverter zog | Min cable loj rau 12V | Min cable loj rau 24V | Min cable loj rau 48V |
|---|---|---|---|
| 1000W | 25mm² (3 AWG) | 16 mm² (5 AWG) | 10 mm² (7 AWG) |
| 2000W | 50 mm² (1/0 AWG) | 25mm² (3 AWG) | 16 mm² (5 AWG) |
| 3000W | 70mm² (2/0 AWG) | 35mm² (2 AWG) | 25mm² (3 AWG) |
| 5000W | Tsis pom zoo rau 12V | 70mm² (2/0 AWG) | 35mm² (2 AWG) |
Peb txoj cai ntxiv:
Ntev ntev xav tau cov kab tuab tuab (ntxiv 20% ntxiv hla-section ib meter ntxiv)
Siv tooj liab xaim yog ua tau. Yog tias koj siv aluminium, mus 30% thicker
Tighten tag nrho cov kev sib txuas. Ib qho kev sib txuas xoob ua rau muaj cua sov siab
yuam kev 3: Rov qab Polarity - Kev puas tsuaj tam sim
Yuav ua li cas?
Liab mus rau dub. Dub mus rau liab.
Ib ob. Los yog kov xwb.
Qee cov inverters muaj kev tiv thaiv rov qab polarity. Tab sis yog tias koj li tsis ua, lossis lub diode tsis tuaj yeem tswj qhov kev nce siab, ntawm no yog qhov tshwm sim: capacitors tawg. MOSFETs luv luv. Lub Circuit Court kub kub.Yuav kho tsis tau.
Yuav ua li cas kom raug:
Siv lub tshuab ntsuas ntau los xyuas cov roj teeb polarity ua ntej txuas (liab sojntsuam rau qhov zoo, dub rau qhov tsis zoo - koj yuav tsum pom qhov zoo voltage)
Siv cov xim sib txawv rau cov xov hlau:liab rau qhov zoo, dub rau qhov tsis zoo. Tsis txhob siv tib xim.
Yog tias ua tau, siv ntau hom connector rau qhov zoo thiab tsis zoo terminals
Txuas lub roj teeb zookawg. Muaj ib lub tshuab tua hluav taws nyob ze ntawm rooj plaub
Daim ntawv qhia txog kev tiv thaiv:Peb CHNB-M, X, C, thiab E series muaj kev tiv thaiv rov qab polarity. Txawm hais tias koj thim rov qab qhov kev sib txuas, qhov hluav taws xob sab hauv yuav tsis hlawv. Tab sis kev tiv thaiv muaj kev txwv - tso nws rov qab mus rau lub sijhawm ntev tseem tuaj yeem ua rau muaj kev puas tsuaj. Ib txwm txuas kom raug.
Yug 4: Tsis muaj av - lossis tsis muaj av
Yuav ua li cas?
Tsis muaj kev sib txuas hauv av kiag li. Lossis cov av xaim mus rau cov kav dej, cov kav dej cua sov, lossis cov pas nrig. Los yog ib tug neeg siv lub roj teeb tsis zoo li hauv av.
Tsis muaj grounding txhais tau tias: yog tias cov khoom xau tam sim no, cov ntaub ntawv hlau tuaj yeem ua neej nyob. Koj kov nws - koj poob siab. Qhov phem tshaj, thaum xob laim los yog kab sib chaws tshwm sim, lub zog tsis muaj qhov mus. Nws tag nrho mus rau hauv koj cov khoom siv. Txhua yam kub hnyiab.
Yuav ua li cas kom raug:
| Qhov system tivthaiv | Kev xav tau hauv av |
|---|---|
| Hnub ci vaj huam sib luag ncej | Sib cais hauv av (xov xwm tiv thaiv) |
| Inverter rooj | Txuas rau hauv av (kev nyab xeeb hauv av) |
| Roj teeb lub thawv | Yog tias rooj plaub hlau, av nws thiab |
| AC tso zis (neutral hlau) | Tej zaum yuav xav tau rov- grounding ib lub zos code |
Cov ntsiab lus tseem ceeb:
Siv lub tsheb npav tooj liab tshwj xeeb hauv av
Hauv av hlau loj: tsawg kawg yog 50% ntawm qhov loj tshaj tam sim no - nqa hlau
Kev tiv thaiv hauv av: tsawg dua 4Ω (tus kws tshaj lij tuaj yeem ntsuas qhov no)
Tsis txhobtxuas lub inverter's AC tso zis nruab nrab ncaj qha rau roj teeb tsis zoo
Qhov yuam kev 5: Txhim kho hauv qhov chaw kaw - Lub caij ntuj sov tig nws mus rau hauv qhov cub
Yuav ua li cas?
Koj muab lub inverter thiab roj teeb rau hauv ib lub txee me me. Koj kaw qhov rooj. Lub caij ntuj sov los.
Lub inverter ua kom sov thaum khiav. Lub roj teeb ua kom sov thaum them nyiaj. Qhov chaw nyob. Tsis muaj cua. Kub nce mus rau 60 degree, 70 degree, 80 degree.
Tom qab ntawd:
Electrolytic capacitors poob ib nrab ntawm lawv lub neej rau txhua txhua 10℃nce
Fais fab transistors poob efficiency thiab tej zaum yuav thermally tawg
LFP roj teeb muaj kev nyab xeeb dua NMC, tab sis qhov kub thiab txias tseem muaj hnub nyoog lawv sai dua
Yuav ua li cas kom raug:
Tawm musyam tsawg kawg yog 15 cmntawm qhov chaw nyob ib ncig ntawm lub inverter rau airflow
Ntxivyuam cov kiv cua txiasmus rau lub txee (siv lub ntsuas kub los tswj lawv)
Tsis txhob tso lub inverterncaj qha saum toj nolub roj teeb ( cua kub nce - lub roj teeb txawm kub)
Yog tias txhim kho sab nraum zoov, xaiv antxoov ntxoo, qhuav, zoo -ventilatedchaw
Kev ntsuas kub:
Ua haujlwm kub zoo tshaj plaws: 20 ℃ - 30 ℃
Tso cai rau peb cov khoom: -25℃- +70 degree
Ntev - lub sij hawm raug tshaj 50℃: lifespan poob qis heev
Tshaj 70℃: tshaj- tiv thaiv kub tuaj yeem kaw lub tsev
Qhov yuam kev 6: Cov roj teeb tsis raug Series / Parallel Wiring - Qhov tsis sib xws ua rau ua tsis tiav thaum ntxov
Yuav ua li cas?
Ib tug neeg yuav ob lub roj teeb 12V. Lawv txuas lawv hauv series los ua 24V. Tab sis cov roj teeb muaj hnub nyoog sib txawv, txawv hom, muaj peev xwm sib txawv.
Los yog lawv txuas peb lub roj teeb nyob rau hauv parallel, tab sis cov xaim tsis raug. Lub roj teeb nruab nrab tau txais tam sim no tshaj plaws. Nws ua tsis tau ua ntej.
Nrog rau cov kev sib txuas ua ke: thaum them nyiaj, lub roj teeb me me puv ua ntej, tom qab ntawd tau txais ntau dhau. Thaum tso tawm, lub roj teeb me me ua ntej, tom qab ntawd tau tshaj - tawm. Tom qab ob peb lub voj voog, lub roj teeb "tsis muaj zog tshaj plaws" tau tuag.
Nrog rau kev sib txuas sib txuas: yog tias cov xaim tsis sib luag, lub roj teeb ze tshaj plaws rau lub inverter nqa ntau dua tam sim no. Lwm tus zaum rov qab thiab ua haujlwm tsawg dua.
Yuav ua li cas kom raug:
Series (kom nce voltage):
Siv tib hom, tib lub qauv, tib lub roj teeb
Ua kom them txhua lub roj teeb ib tus zuj zus ua ntej txuas hauv koob
Ntxiv ibroj teeb balancerlos yog siv BMS nrog kev sib npaug
Parallel (kom nce peev):
Tib hom, tib qauv, tib batch yuav tsum tau
Siv kab pheeb ces kaum (saib daim duab hauv qab no)
Tsis txhob sib npaug ntau tshaj 4 lub roj teeb (kev sib koom tam sim no nyuaj)
yuam kev 7: Inverter dhau deb ntawm roj teeb - Voltage poob nyiag koj lub zogYuav ua li cas?
Koj muab lub inverter tso rau hauv chav nyob. Lub roj teeb nyob ntawm lub sam thiaj. Cable ntev yog 5 meters.
Koj siv 25mm² tooj liab hlau. Koj xav tias txaus.
Ntawm 2000W load ntawm 12V system, tam sim no yog li 185A. Voltage poob tshaj 5 meters ntawm 25mm² tooj liab? Txog 0.7V.
Roj teeb voltage yog 12.8V. Ntawm lub inverter, nws poob rau 12.1V. Lub inverter qhov tsis tshua muaj hluav taws xob kaw feem ntau yog nyob ib puag ncig 10.5V, yog li koj tseem tsis tau kaw. Tab sis voltage poob txhais tau tias: lub inverter qhov tseeb tso zis hwj chim poob, thiab cov cables kub.
Yuav ua li cas kom raug:
Golden txoj cai: muab lub inverter kom ze rau lub roj teeb li sai tau.
Zoo tagnrho nrug:hauv 1 meter
Txais kev ncua deb:hauv 3 meters(yuav tsum tau thicker cable)
Ntau tshaj 5 meters:xav txog kev hloov mus rau 24V lossis 48V
Kev hloov kho cable rau ntev dua (piv txwv: 2000W, 12V):
| Nyob deb | Cable loj xav tau |
|---|---|
| Hauv 1 meter | 50mm 2 |
| 3 m ib | 70mm 2 y |
| 5 m ib | 95mm wb |
| 10 meters | Tsis pom zoo rau 12V |
Vim li cas 48V thiaj li zoo dua (2000W load):
12V system: 167A tam sim no, xav tau 70mm² cable rau 5 meters
48V system: 42A tam sim no, xav tau tsuas yog 16mm² cable rau 5 meters
High voltage txhais tau tias qis dua tam sim no. Tsawg tam sim no txhais tau hais tias nyias nyias cable, tsawg voltage poob, tsawg poob.
