Lub thawv photovoltaic hlws ris yog ib qho khoom siv sib txuas ntawm lub hnub ci cell array tsim los ntawm lub hnub ci cell modules thiab lub hnub ci them nyiaj tswj cov cuab yeej. Nws lub luag haujlwm tseem ceeb yog txhawm rau txuas thiab tiv thaiv lub hnub ci photovoltaic modules, txuas lub zog tsim los ntawm lub hnub ci hlwb mus rau sab nraud circuits, thiab ua cov photovoltaic tam sim no tsim los ntawm cov khoom siv.
Lub thawv sib txuas muaj ob txoj haujlwm: kev sib txuas thiab kev tiv thaiv. Kev sib txuas ua haujlwm yog kos tawm tam sim no tsim los ntawm photovoltaic modules thiab qhia nws mus rau hauv cov khoom siv hluav taws xob los ntawm cables thiab connectors. Txhawm rau txo qhov poob ntawm lub thawv sib txuas nws tus kheej, cov khoom siv hluav taws xob ntawm tus kheej thiab kev tiv thaiv yuav tsum tau ua kom tsawg li tsawg tau. Kev tiv thaiv muaj nuj nqi muaj ob ntu. Ib qho yog los tiv thaiv cov photovoltaic modules los ntawm bypass diodes thiab txhim kho lub hwj chim tso zis ntawm photovoltaic modules nyob rau hauv txhaum tej yam kev mob xws li shading. Lwm qhov yog kom ua tiav lub hom phiaj ntawm waterproofing thiab fireproofing thiab txo cov kev khiav hauj lwm kub ntawm lub junction box los ntawm tshwj xeeb cov ntaub ntawv sealing thiab tshav kub dissipation tsim. , yog li tiv thaiv photovoltaic modules thiab txo qhov poob ntawm photovoltaic module tso zis zog los ntawm bypass diode to tam sim no.
Raws li lub zog ntawm cov khoom siv roj teeb txuas ntxiv zuj zus, roj teeb hloov pauv kev ua tau zoo kuj tseem nce xyoo los ntawm xyoo, thiab kev ua haujlwm tam sim no hauv photovoltaic system nce ntau. Raws li ib qho tseem ceeb kev sib txuas thiab kev tiv thaiv ntaus ntawv ntawm cov roj teeb modules, lub junction box yog lub luag hauj lwm rau lub hwj chim tso zis thiab kab kev tiv thaiv ntawm photovoltaic modules, yog li nws yuav tsum muaj ib tug ntau dua tam sim no nqa peev xwm.
Lub peev xwm nqa tam sim no muaj feem cuam tshuam nrog ntau qhov ntsuas xws li cua sov dissipation, conduction efficiency, kev ntseeg siab thiab kev ua siab ntev. Yog li ntawd, photovoltaic module junction box manufacturing tuam txhab uas muag yuav tsum tau tswj synchronized technological innovation kom hloov mus rau txoj kev loj hlob sai ntawm cell technology. Photovoltaic module hlws ris thawv yog txav mus rau siab dua tam sim no nqa peev xwm, zoo dua tshav kub dissipation muaj peev xwm, siab zog system stability, thiab qis zog noj. Trends xws li cov nqi tsim khoom tsim.
Kev loj hlob theem ntawm photovoltaic hlws ris thawv
Nyob rau hauv xyoo tas los no, raws li kev ua tau zoo ntawm cov khoom siv hluav taws xob photovoltaic txuas ntxiv txhim kho, kev ua lag luam tau nce siab dua qhov yuav tsum tau muaj rau lub peev xwm nqa tam sim no, muaj peev xwm ua kom sov, thiab kev ruaj ntseg ntawm cov khoom sib txuas. Junction box khoom kuj tau dhau los ntawm ntau qhov kev rov ua dua.
Los ntawm qhov ntxov tshaj plaws sealing nplhaib hlws ris lub thawv nrog cov txheej txheem nyuaj rau cov kua nplaum uas muaj qhov sib txuas nrog cov txheej txheem yooj yim, kev sib khi zoo dua, me me, thiab qib siab dua ntawm automation; los ntawm ib lub thawv sib txuas nrog ntau cov ntaub ntawv mus rau qhov chaw sib txuas Ib lub thawv sib txuas uas yog me dua, txuag cov ntaub ntawv thiab muaj cov nyhuv thermal dissipation zoo dua. Junction box khoom yog pheej nrhiav kev ua tau zoo ntawm cov nqi qis hauv kev sib tw ua lag luam, thiab yuav txuas ntxiv mus ntxiv rau yav tom ntej.

Kev tsom xam ntawm qhov ua tsis raug ntawm cov thawv sib txuas
1. Feem ntau ua txhaum ntawm junction box
Feem ntau ua txhaum ntawm lub photovoltaic module hlws ris lub thawv ntawm qhov project site muaj xws li: kev laus thiab deformation ntawm lub cev lub cev, tsis muaj tseeb soldering nyob rau hauv lub junction box, tawg tsis ua hauj lwm ntawm bypass diode, burnt hlws ris lub thawv, thiab sib cais ntawm lub hlws ris lub thawv los ntawm silicone.
2. Kev txheeb xyuas cov ntsiab lus txhaum cai ntawm cov thawv sib txuas
Kev ua tsis tiav 1: Cov txheej txheem vuam txheej txheem teeb meem zoo
Nyob rau hauv lub hlws ris lub thawv, muaj ib tug tsis muaj zog solder nyob rau hauv kev sib txuas ntawm diode tus pin thiab tooj liab conductor, thiab nyob rau hauv kev sib txuas ntawm lub tsheb npav bar thiab tooj liab conductor. Thaum lub photovoltaic module raug thaiv los ntawm duab ntxoov ntxoo los yog lwm yam teeb meem ua rau lub bypass diode tig rau, lub soldered sib koom yuav kub. Thaum qhov sib koom ua ke yog Thaum cov cua kub sib sau ntau tshaj qhov kub ntawm thermal deformation ntawm cov khoom siv hluav taws xob sib txuas, lub thawv sib txuas yuav raug kev laus thiab deformation. Lub bypass diode tau qhib ntev dua, qhov kev pheej hmoo ntawm deformation thiab kev laus ntawm lub thawv sib txuas ntau dua. Thaum qhov kub siab tshaj qhov siab tshaj qhov siab ntawm diode hlws ris kub, qhov kub thiab txias Nws yuav ua rau thermal tawg ntawm lub bypass diode thiab txawm hlawv lub hlws ris lub thawv.
Failure txoj cai 2: Cov txheej txheem sealing zoo teeb meem
Muaj kev sib kis thaum lub sij hawm gluing txheej txheem ntawm lub hlws ris lub thawv thiab lub photovoltaic module backplane, uas ua rau lub hlws ris lub thawv cais los ntawm silicone tom qab.
Fault Principple 3: Duab ntxoov ntxoo occlusion, zais kab nrib pleb thiab lwm yam teeb meem
Photovoltaic modules raug rau tej yam kev mob xws li ntxoov ntxoo, kab nrib pleb, thiab cov chaw kub hauv zos rau lub sij hawm ntev, uas ua rau lub bypass diode nyob rau hauv tsis tu ncua ua hauj lwm rau lub sij hawm ntev, ua rau lub junction kub ntawm lub bypass diode nce. Thaum qhov kub ntawm qhov sib txuas nkag mus rau ib theem, lub bypass Lub diode yuav ua tsis tiav vim thermal tawg. Yog tias tsis ua raws li lub sijhawm, thaum lub tshav kub sib xyaw nce mus txog qhov kub thiab txias ntawm cov khoom siv rwb thaiv tsev ntawm lub thawv sib txuas, lub thawv sib txuas yuav deform thiab hnub nyoog. Hauv qhov xwm txheej hnyav, lub thawv sib txuas yuav hlawv tawm.
Lub hauv paus ntsiab lus ua tsis tiav 4: xob laim ntaus
Thaum lub photovoltaic module raug ntaus los ntawm xob laim, lub bypass diode yuav tam sim ntawd tawg los ntawm high voltage. Thaum cov nag dhau los thiab lub ntuj tau tshem tawm, raws li qhov qub module tam sim no ntws los ntawm lub diode tsis ua haujlwm ntev, lub diode yuav ua kom sov. Thaum tshav kub kub accumulates mus rau ib theem, nws yuav ua rau aging thiab deformation ntawm junction box, los yog txawm hlawv lub hlws ris box.
Cov ntsiab lus
Photovoltaic fais fab chaw nres tsheb yuav tsum ua kom muaj kev ruaj ntseg thoob plaws hauv lub neej voj voog, thiab kev ntseeg siab ntawm cov khoom siv raws li lub hauv paus rau kev ua kom cov neeg siv khoom rov qab los ntawm kev nqis peev thiab paub txog cov neeg siv khoom muaj nqis. Raws li ib feem tseem ceeb ntawm photovoltaic modules, lub thawv sib txuas yuav ua rau txo qis hauv lub zog tsim hluav taws xob ntawm qhov chaw nres tsheb photovoltaic thaum nws ua tsis tiav. Hauv qhov xwm txheej hnyav, nws tuaj yeem ua rau hluav taws. Tam sim no, kev soj ntsuam pom, infrared thermal imaging technology, thiab IV xeem txoj kev yog feem ntau siv nyob rau hauv sab nraum zoov photovoltaic fais fab chaw nres tsheb los txiav txim junction box faults. Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho cov cuab yeej ntse, txoj hauv kev yooj yim dua xws li inverter ntse IV scanning thiab fais fab chaw ntsuas qhov system software tau dhau los. , ntxiv nthuav qhov system sab txoj kev ntawm kev kuaj xyuas photovoltaic module junction box faults. Tom qab qhov tam sim no loj leap rau pem hauv ntej ntawm qhov loj thiab tam sim no ntawm photovoltaic modules, qhov kev pheej hmoo ntawm kev sib txuas lub thawv kev ntseeg siab yuav nce ntxiv. Peb yuav tsum txiav txim siab xaiv cov khoom uas muaj cov khoom zoo, kev ntseeg siab zoo, thiab kev txhawb nqa tom qab muag uas "ua ke nrog cov qauv kev ua neej nyob thoob plaws hauv kev tsim khoom thiab kev siv." "Lub taub hau cov khoom sib txuas hauv txhua qhov txuas kom tsis txhob zais qhov phom sij los ntawm cov txheej txheem tsis zoo xws li vuam tsis raug; thaum lub sij hawm thauj khoom thiab kev teeb tsa, kev saib xyuas cov khoom yuav tsum tau ua kom txo qis qhov tshwm sim ntawm cov khoom tawg; thaum lub sij hawm ua haujlwm txhua hnub thiab kev tu, Nws yog ib qho tsim nyog yuav tsum tau ua. ua haujlwm zoo hauv kev tiv thaiv xob laim thiab kev daws teeb meem ntawm cov chaw nres tsheb fais fab thaum muaj teeb meem xws li cov duab ntxoov ntxoo, kub qhov chaw, tawg, thiab lwm yam. hlws ris box.
