     Hnub ci PV connectorsua lub luag haujlwm tseem ceeb hauv kev xaim ntawm hnub ci arrays.Raws li tsim, lawv muab cov hluav taws xob siab, siab tam sim no, tsis tshua muaj kev sib txuas DC yog tias ntsia tau raug, thiab lawv cov vaj tsev tsis muaj dej tsis zoo, tiv taus kub, UV tiv taus, thiab muaj kev cia siab txog li 25 xyoo lossis ntau dua.Tsis tas li ntawd, lawv cov snap-ua ke kev sib txuas thev naus laus zis ua rau kev teeb tsa hnub ci arrays.Txawm li cas los xij, PV connectors feem ntau yog lub hauv paus ntawm hnub ci array tsis ua haujlwm.

Ib txoj kev tshawb fawb los ntawm Fraunhofer lub koom haum rau Hnub Ci Zog Systems ISE ntawm Freiburg, Lub teb chaws Yelemees, tau tshuaj xyuas qhov ua rau thermal tsis ua haujlwm ntawm PV arrays thiab pom tias hnub ci PV txuas thiab crimps yog qhov loj tshaj plaws ua rau DC thaiv tsis ua haujlwm.Feem ntau ntawm cov kev ua tsis tiav no tau tshwm sim thaum thawj tsib xyoos ntawm kev teeb tsa, ua rau cov kws tshawb fawb xav tias kev teeb tsa tsis zoo yog qhov tseem ceeb.

Kev sib tham ntawm no hauv Tebchaws Meskas nrog cov kws tshuaj ntsuam xyuas hluav taws xob kuj tau ua tiav cov kev nkag siab hauv qab no rau PV connector tsis ua haujlwm:

Ntau tus kws tshuaj ntsuam xyuas kuj tau pom cov chaw teeb tsa ua haujlwm crimping PV connectors 'kev sib cuag nrog cov pliers.Cov lus hais ntxiv tau hais txog qhov "xoo" haum ntawm PV txuas ntawm cov tuam txhab sib txawv.

Compounding lub array tsis ua hauj lwm ntawm hnub ci PV connectors yog tias nws yuav nyuaj rau pom kev sib dhos tsis raug thiab tsis zoo hu crimps.Kev sib txuas tsis ua haujlwm feem ntau muab zais rau hauv cov khoom sib txuas uas zoo li ua rau kev sib cuag zoo.Tshwj tsis yog tias lub connector yog kiag li faulty, xws li ib tug deformed los yog melted connector, nws yog yuav luag tsis yooj yim sua kom ntes tau ntawm qhov muag liab qab.Thermal imaging feem ntau yog tib txoj kev los xyuas cov teeb meem no.Lub zog poob, kuaj xyuas thiab kho cov nqi cuam tshuam nrog cov kev ua tsis tiav no tuaj yeem siab.

Hnub ci PV connector tsis ua hauj lwm tuaj yeem muab faib ua ob thaj chaw: teeb meem tsis sib haum xeeb thiab teeb meem txuas txuas.Factory-installed connectors nyob rau sab nraum qab ntawm PV modules feem ntau tsis yog lub hauv paus ntawm cov teeb meem, thiab feem ntau ntawm cov kev tsis ua hauj lwm no muaj feem xyuam rau thaj chaw thaiv.Txawm li cas los xij, cov khoom sib txuas hauv teb xws li cov rau hauv tsev-khiav txoj hlua kawg siv nrog hlua thiab lwm yam hauv nruab nrab inverters tuaj yeem teeb meem.

Incompatibility teeb meem feem ntau tshwm sim los ntawm mating ntawm photovoltaic connectors los ntawm txawv manufacturers.Txawm hais tias muaj ntau qhov sib txuas tau suav tias yog "sib npaug," tsis muaj kev lag luam tus qauv rau kev tsim cov khoom sib txuas.Vim qhov sib txawv ntawm kev tsim qauv, cov cuab yeej crimp xav tau thiab cov ntaub ntawv tiv tauj thiab vaj tse, kev pom hluav taws xob zoo tsis tuaj yeem lav.Tsis tas li ntawd, thaum tag nrho cov PV connectors yuav tsum tau kuaj rau UL 6703, tus qauv no tsis npog cov mating ntawm connectors los ntawm txawv manufacturers tshwj tsis yog tshwj xeeb kuaj - ib yam dab tsi tsis tshua muaj ua.Qee cov tuam txhab lag luam ceeb toom tawm tsam kev sib tw ntawm cov khoom sib txuas sib txawv, thiab cov kev pom zoo yuav tsum ua raws.

Feem ntau cov hnub ci PV connectors siv crimp-style hu.Txawm hais tias lub Hoobkas- lossis chaw teeb tsa, cov khoom sib txuas no yuav tsum muaj cov cuab yeej tsim khoom-pom zoo crimp thiab kev sib dhos kom raug rau kev teeb tsa tsis muaj teeb meem.Crimp cuab tam calibration yuav tsum thiab crimp tuag txwv yuav tsum tau ua raws li rau cov teeb meem-dawb installation nyob rau hauv lub neej ntawm lub hnub ci array.Cov cuab yeej tshiab-tsawg PV txuas tam sim no muaj thiab.Cov connectors no tshem tawm cov cuab yeej thiab kev sib dhos yuav tsum tau, lawv siv qhov kub thiab txias- thiab kev co-resistant caij nplooj ntoos hlav tiv tauj rau cov xov hlau sib txuas.

Txoj kev daws teeb meem ntawm photovoltaic connector tsis ua hauj lwm yog los xyuas kom meej qhov tseeb installation thaum lub sij hawm pib xaim ntawm PV array.Qee qhov kev coj ua zoo tshaj plaws uas tuaj yeem siv los ua kom tiav qhov no yog:

Ntxiv nrog rau cov kev sib tw ntawm kev sib dhos kom zoo ntawm lub hnub ci PV connectors, muaj qhov teeb meem ntawm incompatible PV connector mating.Cov kev coj ua zoo tshaj plaws hauv cheeb tsam no suav nrog ib txwm hais txog tib lub npe ntawm cov khoom sib txuas raws li cov khoom siv los ntawm PV module chaw tsim khoom.Qhov no suav nrog kev siv microinverters thiab optimizers.Qee cov tuam txhab lag luam no tau ua qhov no yooj yim dua hauv qee kis los ntawm kev muab kev xaiv ntawm PV connector hom ntawm lawv cov khoom siv.

Kev siv PV connectors los ntawm tib lub chaw tsim khoom, kev cob qhia kom zoo, cov cuab yeej crimp pom zoo lossis kev siv cov cuab yeej-tsawg lub caij nplooj ntoos hlav hu rau PV connectors tuaj yeem pab txo qhov cuam tshuam ntawm kev sib txuas tsis ua haujlwm.
