Xaiv lub hnub ci PV Junction Box

Cov ntaub ntawv tseem ceeb uas yuav tsum tau xav txog hauv kev xaiv PV hlws ris lub thawv yuav tsum yog tam sim no ntawm lub module.Ib qho yog qhov siab tshaj plaws ua haujlwm tam sim no thiab lwm qhov yog qhov luv-circuit tam sim no.Tau kawg, qhov luv-circuit tam sim no yog qhov siab tshaj plaws tam sim no uas lub module tuaj yeem tso tawm.Raws li qhov luv-circuit tam sim no, qhov ntsuas tam sim no ntawm lub thawv sib txuas yuav tsum muaj qhov muaj kev nyab xeeb loj dua.Yog hais tias lub hnub ci PV hlws ris lub thawv raug xam raws li qhov siab tshaj plaws ua haujlwm tam sim no, qhov kev nyab xeeb me me.
Lub hauv paus kev tshawb fawb tshaj plaws rau kev xaiv yuav tsum yog raws li txoj cai hloov pauv ntawm qhov tam sim no thiab qhov hluav taws xob ntawm lub roj teeb uas yuav tsum tau muab tshem tawm nrog kev siv ntawm lub teeb.Koj yuav tsum nkag siab txog thaj chaw uas lub module koj tsim tau siv, thiab lub teeb loj npaum li cas nyob rau hauv cheeb tsam no, thiab tom qab ntawd sib piv cov roj teeb Qhov kev hloov nkhaus ntawm qhov tam sim no ntawm cov nti nrog qhov siv ntawm lub teeb, tshawb xyuas qhov ua tau siab tshaj plaws tam sim no, thiab tom qab ntawd xaiv qhov ntsuas tam sim no ntawm lub thawv sib txuas.

1. Raws li lub zog ntawm photovoltaic module, 150w, 180w, 230w, lossis 310w?
2. Lwm yam tshwj xeeb ntawm cov khoom.
3. Cov tsis muaj diode, 10amp, 12amp, 15amp lossis 25amp?
4. Lub ntsiab lus tseem ceeb tshaj plaws, qhov luv-circuit tam sim no loj npaum li cas?Rau qhov kev ntsuam xyuas no, kev xaiv ntawm diode nyob ntawm cov khoom hauv qab no:
Tam sim no (loj dua yog qhov zoo dua), qhov siab tshaj qhov sib txuas kub (me me yog qhov zoo dua), thermal tsis kam (me dua yog qhov zoo dua), qhov hluav taws xob poob (me me zoo dua), rov qab tawg voltage (feem ntau 40V yog nyob deb txaus).

Split Junction Box

Raws li lub Rau Hli 2018, lub hnub ci hleb lub thawv tau maj mam muab tau ib ceg los ntawm thawj lub thawv sib txuas hauv xyoo 2015:split hlws ris box, thiab tsim ib tug scale nyhuv ntawm Shanghai Photovoltaic Exhibition, uas sawv cev rau qhov muaj peev xwm ntawm PV hlws ris thawv nyob rau hauv lub neej yav tom ntej Nkag mus rau tus qauv ntawm diversification thiab parallel txoj kev loj hlob.
Ib-thooj hlws ris lub thawv yog tsuas yog siv rau cov tsoos thav duab Cheebtsam, thiab split-hom hlws ris thawv yog tsuas yog siv rau tshiab ob-iav ob-sided Cheebtsam.Piv nrog rau yav dhau los, qhov kawg yuav xav tau ntau dua los ntawm kev ua lag luam thiab cov neeg siv khoom tam sim no.Tom qab tag nrho, nws yog tam sim no kom paub meej tias tus nqi ntawm photovoltaic fais fab tuag yog tsawg dua li cov nqi hluav taws xob, uas txhais tau hais tias tus nqi ntawm photovoltaic kev lag luam yuav raug txo ntxiv, thiab cov nyiaj tau los ntawm photovoltaic hlws ris lub thawv yuav raug ntxiv.Lub thawv sib cais yog yug los nrog lub hom phiaj ntawm "txo tus nqi" thiab txhim kho tas li.

Qhov zoo ntawmPeb-Split Junction Box

1. Zoo txo ​​qhov ntim thiab potting.Lub thawv ib lub cev tsuas yog 3.7ml, uas txo cov nqi tsim khoom, thiab qhov zoo ntawm qhov me me no ua rau thaj chaw sib txuas ntawm lub module me me, ua kom lub teeb pom kev ntawm lub vaj huam sib luag photovoltaic, kom tus neeg siv lub tshuab hluav taws xob photovoltaic tuaj yeem tau txais. cov txiaj ntsig zoo dua.

2. Optimize lub plhaub qauv, thiab cov nyhuv anti-aging yog ho nce.Hom tshiab ntawm qhov sib cais lub thawv no tau txais kev tshawb fawb thiab kev tsim kho tshiab, thiab nws lub plhaub (lub thawv sib txuas, txuas) muaj peev xwm tiv thaiv kev laus thiab dej tsis zoo, thiab tuaj yeem siv tau ib txwm nyob rau hauv ib puag ncig hnyav.

3. Qhov nruab nrab ntawm qhov kev txhim kho lub tsheb npav tsuas yog 6 hli, thiab lub diode txais kev sib tw vuam, kev sib txuas ua kom muaj kev nyab xeeb thiab txhim khu kev qha.

4. Cov nyhuv thermal dissipation zoo dua.Piv nrog rau lub thawv sib txuas, lub thawv sib cais ua kom muaj cua sov tsawg dua thiab muaj cov cua sov zoo dua.

5. Txuag qhov ntev ntawm lub cable, thiab txo tus nqi tiag tiag thiab ua kom muaj txiaj ntsig zoo.Cov qauv tsim peb feem tseem hloov pauv txoj kev teeb tsa thiab qhov hluav taws xob, kom lub thawv zoo thiab qhov tsis zoo tuaj yeem ntsia tau rau sab laug thiab sab xis ntawm lub vaj huam sib luag photovoltaic, uas ua rau qhov kev ncua deb ntawm lub roj teeb vaj huam sib luag thiab kev sib txuas ntawm cov hluav taws xob. roj teeb vaj huam sib luag thaum lub sij hawm engineering installation.Txoj kev ncaj-tawm no tsis yog tsuas yog txo cov cables xwb, tab sis kuj txo qhov poob ntawm lub zog tsim los ntawm txoj kab ntev, thiab ua kom lub zog ntawm lub module.

Ntawm tag nrho, lub thawv tshiab peb-sib cais tuaj yeem piav qhia raws li tus qauv ntawm "zoo thiab tus nqi qis", thiab tau dhau los ntawm TUV tus qauv tshiab (IEC62790).Txoj kev vam meej ntawm kev sib cais lub thawv sawv cev tias Tuam Tshoj muaj txoj haujlwm zoo dua hauv kev sib tw ntawm photovoltaic daim phiaj sib luag.

Supplement: Evolution of Solar PV Junction Boxes

Hnub ci PV hlws ris lub thawv tau ib txwm tswj hwm qhov ua haujlwm zoo ib yam, tab sis tam sim no raws li cov khoom siv hluav taws xob thiab qhov hluav taws xob ntawm cov hnub ci hluav taws xob nce, lub hnub ci hlws ris lub thawv yuav tsum txhim kho lub peev xwm los tiv thaiv lub zog.

Brian Mills, North American PV Product Manager ntawm Stäubli Electrical Connectors tau hais tias "Lub luag haujlwm dav dav ntawm lub thawv sib txuas tseem zoo ib yam, tab sis PV modules tau txais ntau dua thiab muaj zog dua," said Brian Mills, North American PV Product Manager ntawm Stäubli Electrical Connectors."Raws li PV modules tau txais cov zis ntau dua thiab ntau dua, cov bypass diodes yuav tsum ua haujlwm ntau dua.Txoj kev uas lawv nqus tau lub zog yog kom dissipate tshav kub, yog li qhov kub ntawm lub diodes yuav tsum tau daws nrog. "

Txias bypass keyboards yog hloov cov tsoos diodes nyob rau hauv ib co PV hlws ris thawv kom txo tau cov cua sov ntau dhau los ntawm ntau dua PV module outputs.Thaum lub hnub ci vaj huam sib luag xav kom dissipate lub zog instinctively, cov pa diodes tiv thaiv qhov tsis tshwm sim, tab sis tsim kom muaj cua sov hauv cov txheej txheem.Ib qho kev hloov pauv txias ua haujlwm zoo li kev hloov pauv hauv / tawm, qhib lub voj voog thaum lub hnub ci vaj huam sib luag sim nqus lub zog, tiv thaiv kev kub ntxhov.

"Bypass diodes yog 1950s thev naus laus zis," Mills hais."Lawv yog rugged thiab txhim khu kev qha, tab sis qhov teeb meem kub ib txwm muaj teeb meem."Txias bypass keyboards daws qhov teeb meem kub no, tab sis lawv kim dua li diodes, thiab txhua tus xav tau lub hnub ci PV modules kom pheej yig li sai tau.

Kom tau txais txiaj ntsig zoo tshaj plaws rau lawv cov nyiaj, ntau tus tswv PV system tau tig mus rau lub hnub ci bifacial.Txawm hais tias hluav taws xob yog tsim rau pem hauv ntej thiab sab nraum lub hnub ci vaj huam sib luag, lub zog tseem tuaj yeem nkag los ntawm lub thawv sib txuas.PV junction box manufacturers yuav tsum tau innovate nrog lawv cov qauv.

Rosenkranz tau hais tias "Ntawm lub hnub ci bifacial, koj yuav tsum muab lub thawv PV hlws ris rau ntawm ntug qhov uas koj tuaj yeem ua kom lub nraub qaum tsis muaj qhov ntxoov ntxoo," Rosenkranz hais."Ntawm ntawm ntug, lub thawv sib txuas tsis tuaj yeem ua duab plaub, nws yuav tsum me me."

TE Connectivity muaj peb lub me me SOLARLOK PV Edge hlws ris thawv rau bifacial PV modules, ib qho nyob rau hauv sab laug, nruab nrab, thiab sab xis ces kaum ntawm lub module, uas yeej ua hauj lwm tib lub hom phiaj raws li ib tug loj lub thawv.Stäubli tab tom tsim lub PV hlws ris lub thawv rau qhov chaw nyob ntawm qhov tseeb ntawm ob sab modules.

Qhov nrov nrov ntawm bifacial PV modules txhais tau hais tias PV hlws ris lub thawv tsim yuav tsum tau kho dua tshiab hauv lub sijhawm luv luv.Lwm qhov kev hloov kho tam sim ntawd rau lub hnub ci suav nrog kev kaw nrawm thiab ntau yam kev tiv thaiv qib uas xav tau los ntawm National Electrical Code, thiab PV hlws ris lub thawv yuav tsum tau khaws cia.

Stäubli's PV-JB / MF multifunction junction box yog customizable nrog qhib hom, yog li nws tuaj yeem npaj rau kev hloov tshiab yav tom ntej, suav nrog tag nrho cov optimizers lossis micro-inverters, yog tias lawv cov khoom siv hluav taws xob ua me me.

TE Connectivity kuj tsis ntev los no qhia txog lub ntse PV hlws ris lub thawv uas sib txuas cov kev cai luam tawm Circuit boards (PCBs) rau hauv lub hnub ci vaj huam sib luag daws teeb meem nrog kev saib xyuas, kev ua kom zoo thiab muaj peev xwm kaw sai.

PV junction box manufacturers tseem tab tom txiav txim siab ntxiv cov tshuab inverter rau lawv cov qauv yav tom ntej.Tsis pom zoo hlws ris thawv yog attracting ntau xim.
