Thaum nws los txog rau photovoltaic connectors, ib tug yuav tsum xav txog Stäubli Group, qhov twg lub ntiaj teb thawj photovoltaic connector tau yug los.“MC 4", ib qho ntawm Stäubli'sTiv tauj ntautag nrho cov khoom siv hluav taws xob sib txuas, tau muaj kev paub dhau los 12 xyoo txij li nws tau qhia hauv xyoo 2002. Cov khoom no tau dhau los ua tus qauv thiab cov qauv hauv kev lag luam, txawm tias cov khoom sib txuas.

Shen Qianping, kawm tiav los ntawm University of Stuttgart, lub teb chaws Yelemees nrog ib tug master's degree hauv hluav taws xob engineering.Nws tau koom nrog kev lag luam photovoltaic rau ntau xyoo thiab muaj kev paub nplua nuj nyob rau hauv kev sib txuas ntawm hluav taws xob.Koom nrog Stäubli Group hauv 2009 ua tus thawj coj ntawm kev txhawb nqa rau cov khoom lag luam photovoltaic.

Shen Qianping tau hais tias cov khoom siv hluav taws xob tsis zoo photovoltaic yuav ua rauhluav taws teeb meem, tshwj xeeb tshaj yog rau rooftop faib tshuab thiab BIPV tej yaam num.Thaum hluav taws tshwm sim, qhov poob yuav loj heev.Nyob rau sab hnub poob ntawm Tuam Tshoj, muaj cua thiab xuab zeb ntau, qhov kub thiab txias sib txawv ntawm nruab hnub thiab hmo ntuj yog qhov loj, thiab kev siv hluav taws xob ultraviolet yog qhov siab heev.Cua thiab xuab zeb yuav cuam tshuam rau kev saib xyuas ntawm photovoltaic fais fab nroj tsuag.Inferior connectors yog laus thiab deformed.Thaum lawv tau disassembled, nws yog ib qho nyuaj rau ntxig lawv dua.Lub ru tsev nyob rau sab hnub tuaj Tuam Tshoj muaj cov cua txias, cov yees txias, chimneys thiab lwm yam kuab paug, nrog rau cov ntsev tsuag huab cua los ntawm hiav txwv thiab cov ammonia tsim los ntawm cov nroj tsuag kho dej khib nyiab, uas yuav corrode lub cev, thiabCov khoom siv tsis zoo connector muaj corrosion tsis kam rau ntsev thiab alkali.

Ntxiv rau qhov zoo ntawm photovoltaic connector nws tus kheej, lwm qhov teeb meem uas yuav ua rau muaj kev phom sij rau kev ua haujlwm ntawm qhov chaw nres tsheb fais fab yogkev sib xyaw ntawm cov khoom sib txuas ntawm cov khoom sib txawv.Nyob rau hauv cov txheej txheem ntawm kev tsim kho photovoltaic system, nws yog ib qho tsim nyog yuav tau yuav cov khoom sib txuas photovoltaic nyias kom paub txog kev sib txuas ntawm cov hlua module rau lub thawv sib txuas.Qhov no yuav koom nrog kev sib tshuam ntawm cov khoom txuas thiab cov module tus kheej txuas, thiab vim yogspecifications, loj thiab kam rau uathiab lwm yam, connectors ntawm cov hom sib txawv tsis tuaj yeem sib raug zoo, thiab covkev tiv thaiv yog loj thiab tsis ruaj khov, uas yuav cuam tshuam loj rau kev nyab xeeb thiab lub zog tsim hluav taws xob ntawm qhov system, thiab nws yog ib qho nyuaj kom tau txais cov chaw tsim khoom los ua lub luag haujlwm rau cov xwm txheej zoo.

Cov duab hauv qab no qhia tau hais tias qhov kub thiab txias tiv thaiv tau txais tom qab TUV sib xyaw thiab ntxig cov khoom sib txawv ntawm cov npe sib txawv, thiab tom qab ntawd sim TC200 thiab DH1000.Lub npe hu ua TC200 yog hais txog qhov kev sim siab thiab qis qis, nyob rau hauv qhov kub ntawm -35 ℃ to +85 ℃, 200 cycle tests yog ua.Thiab DH1000 yog hais txog qhov ntsuas kub damp, uas kav ntev txog 1000 teev nyob rau hauv qhov kub thiab txias thiab cov av noo siab.

 Connector cua sov sib piv (sab laug: kub nce ntawm tib connector; txoj cai: kub sawv ntawm connectors ntawm txawv hom)

Hauv qhov ntsuas kub nce siab, cov khoom sib txuas ntawm cov npe sib txawv tau txuas rau hauv ib leeg, thiab qhov kub nce siab yog pom tseeb ntau dua li qhov tso cai kub ntau.

(Kev tiv thaiv nyob rau hauv kev sib xyaw ntawm cov khoom sib txuas ntawm ntau hom)

Rau kev tiv thaiv kev tiv thaiv, yog tias tsis muaj kev sim ua haujlwm, tsis muaj teeb meem nrog cov khoom sib txuas ntawm cov npe sib txawv txuas rau ib leeg.Txawm li cas los xij, hauv kev xeem D pab pawg (kev ntsuas kev hloov pauv ib puag ncig), cov khoom sib txuas ntawm tib hom thiab qauv tswj kev ua haujlwm ruaj khov, thaumkev ua tau zoo ntawm cov khoom sib txuas ntawm cov npe sib txawv sib txawv heev.

Rau cov khoom sib txuas ntawm cov npe sib txawv uas txuas rau ib leeg, nws qib IP tiv thaiv yog qhov nyuaj rau lav.Ib qho laj thawj tseem ceeb yog qhov ntawdqhov kam rau ua ntawm cov hom sib txawv ntawm cov khoom sib txuas sib txawv.

Txawm hais tias cov khoom sib txuas ntawm cov npe sib txawv tuaj yeem sib phim thaum ntsia, tseem yuav muaj kev sib tw, torsion, thiab cov khoom siv (insulating shells, sealing rings, thiab lwm yam) cuam tshuam kev sib nrig sib.Qhov no yuav tsis ua raws li tus qauv yuav tsum tau ua thiab yuav ua rau muaj teeb meem hauv kev tshuaj xyuas.

Cov txiaj ntsig ntawm kev sib xyaw ua ke ntawm cov khoom sib txuas ntawm ntau hom:xoob kab;qhov kub thiab txias nce ntxiv thiab ua rau muaj kev pheej hmoo ntawm hluav taws kub;deformation ntawm lub connector ua rau cov kev hloov nyob rau hauv airflow thiab creepage deb, ua rau ib tug nias txaus ntshai.

Nyob rau hauv tam sim no photovoltaic fais fab nroj tsuag, qhov tshwm sim ntawm inter-plugging connectors ntawm txawv hom tseem yuav pom.Qhov kev ua haujlwm tsis ncaj ncees no yuav tsis yog tsuas yog ua rau muaj kev pheej hmoo hauv kev lag luam tab sis kuj muaj kev tsis sib haum xeeb.Tsis tas li ntawd, vim hais tias cov kev cai lij choj tseem tsis zoo tag nrho, lub photovoltaic fais fab chaw nres tsheb installer yuav yog lub luag haujlwm rau cov teeb meem tshwm sim los ntawm kev sib nrig sib nkag ntawm ntau hom kev sib txuas.

Tam sim no, kev lees paub ntawm "interplugging" (lossis "compatible") ntawm cov khoom sib txuas yog txwv rau kev siv tib yam khoom tsim los ntawm tib lub khw muag khoom (thiab nws qhov chaw tsim khoom).Txawm hais tias muaj kev hloov pauv, txhua qhov chaw tsim khoom yuav raug ceeb toom kom hloov kho synchronous.Cov txiaj ntsig kev lag luam tam sim no ntawm kev sim ntawm cov khoom sib txuas ntawm cov hom sib txawv uas sib koom ua ke, tsuas yog qhia txog qhov xwm txheej ntawm cov qauv ntsuas lub sijhawm no.Txawm li cas los xij, qhov txiaj ntsig no tsis yog daim ntawv pov thawj uas ua pov thawj qhov siv tau ntev ntawm kev sib txuas sib txuas.

Obviously, kev tiv thaiv kev sib cuag ntawm cov khoom sib txawv ntawm cov hom sib txawv yog qhov tsis ruaj khov, tshwj xeeb tshaj yog nws qhov kev ruaj ntseg ntev yog qhov nyuaj rau lav, thiab cov cua sov ntau dua, uas yuav ua rau muaj hluav taws kub heev.

Hais txog qhov no, cov koom haum kuaj kev tso cai TUV thiab UL tau tshaj tawm cov lus sau tseg tiaslawv tsis txhawb nqa daim ntawv thov ntawm connectors ntawm ntau hom.Tshwj xeeb tshaj yog nyob rau hauv Australia, nws yog ib qho yuav tsum tsis txhob tso cai sib xyaw connector insertion coj cwj pwm.Yog li ntawd, lub connector yuav nyias nyob rau hauv qhov project yuav tsum yog tib lub qauv raws li lub connector ntawm lub tivthaiv, los yog tib series ntawm cov khoom ntawm tib lub chaw tsim tshuaj paus.

Tsis tas li ntawd, lub photovoltaic connector ntawm lub module yog feem ntau ntsia los ntawm lub hlws ris lub thawv chaw tsim tshuaj paus los ntawm automated khoom, thiab cov kev soj ntsuam qhov project yog tiav, yog li ntawd lub installation zoo kuj txhim khu kev qha.Txawm li cas los xij, ntawm qhov chaw ua haujlwm, kev sib txuas ntawm cov hlua module thiab lub thawv sib txuas feem ntau xav tau kev teeb tsa los ntawm cov neeg ua haujlwm.Raws li kev kwv yees, tsawg kawg 200 teeb ntawm photovoltaic connectors yuav tsum tau manually ntsia rau txhua megawatt photovoltaic system.Raws li cov kws tshaj lij kev ua haujlwm zoo tam sim no photovoltaic system installation engineering pab pawg feem ntau tsis tshua muaj, cov cuab yeej teeb tsa siv tsis yog kev tshaj lij, thiab tsis muaj qhov zoo ntawm kev tshuaj ntsuam xyuas txoj kev, qhov txuas txuas kev teeb tsa zoo ntawm qhov project site feem ntau tsis zoo, uas dhau los ua qhov zoo. ntawm lub photovoltaic system Weak point.

Yog vim li cas MC4 tau qhuas los ntawm kev ua lag luam yog tias ntxiv rau kev tsim khoom zoo, nws tseem koom nrog Stäubli's patent:Multilam technology.Multilam tshuab yog tsuas yog ntxiv cov hlau tshwj xeeb shrapnel zoo li lub pluaj ntawm cov txiv neej thiab poj niam connectors ntawm lub connector, hloov tus thawj irregular contact nto, zoo heev ua rau lub zoo kev sib cuag cheeb tsam, tsim ib tug raug parallel Circuit Court, thiab muaj peev xwm nqa tam sim no. , Lub zog poob thiab qhov tsawg kawg nkaus tiv thaiv, cuam tshuam tsis kam, corrosion kuj thiab kub tsis kam, thiab tuaj yeem tswj tau qhov kev ua tau zoo rau lub sijhawm ntev.

Photovoltaic connectors yog ib qho tseem ceeb ntawm kev sib txuas sab hauv ntawm lub tshuab hluav taws xob photovoltaic, tsis tsuas yog muaj coob tus neeg, tab sis kuj koom nrog lwm yam.Vim yog qhov zoo ntawm cov khoom nws tus kheej thiab qhov zoo ntawm kev teeb tsa, piv nrog rau lwm cov khoom, photovoltaic connectors yog qhov feem ntau ntawm qhov system tsis ua haujlwm, thiab muaj kev cuam tshuam tseem ceeb rau lub zog tsim hluav taws xob efficiency thiab nyiaj txiag txiaj ntsig ntawm tag nrho cov kab ke.Yog li ntawd,photovoltaic connector xaiv yuav tsum muaj kev tiv thaiv qis heev, thiab tuaj yeem tswj kev tiv thaiv qis rau lub sijhawm ntev.Piv txwv li, lubSlocable mc4 connectormuaj kev tiv thaiv tiv thaiv tsuas yog 0.5mΩ thiab tuaj yeem tswj tau qhov kev tiv thaiv qis rau lub sijhawm ntev.
