Raws li ib feem tseem ceeb, lubtxuasmuaj kev sib cuag tsis zoo thiab kev ntseeg tau ntev, uas tuaj yeem ua kom muaj kev ua haujlwm zoo thiab muaj kev nyab xeeb ntawm lub chaw nres tsheb fais fab. Ntawm qhov tsis sib xws, qhov kev tiv thaiv tsis tu ncua nce ntxiv yuav ua rau muaj kev pheej hmoo ntawm kev nyab xeeb ntawm txoj haujlwm, uas tuaj yeem ua rau muaj hluav taws kub ceev hauv qhov xwm txheej hnyav. Los ntawm 2010 txog 2017, 27 feem pua ntawm 58 photovoltaic hluav taws xob hauv UK tau tshwm sim los ntawm cov khoom sib txuas; Los ntawm 1995 mus rau 2012, 24 feem pua ntawm 180 photovoltaic hluav taws kub hauv lub teb chaws Yelemees kuj raug ntaus nqi los ntawm connector tsis ua hauj lwm.
Tsab ntawv xov xwm no tsom mus rau kev hloov kho tus qauv txuas thiab cov khoom lag luam iteration, aiming kom kev lag luam muaj kev nkag siab ntau ntxiv ntawm cov keeb kwm txuas txuas thiab tos ntsoov rau yav tom ntej txoj kev loj hlob.
Txheem hloov tshiab
Ulrika frank, Thawj Tswj Hwm ntawm lub koom haum thoob ntiaj teb rau Standardization (ISO), ib zaug tau hais nyob rau hauv nws 2022 Xyoo Tshiab cov lus, "cov qauv yog ib qho cuab yeej tseem ceeb los daws ntau yam teeb meem los ntawm tsoom fwv mus rau cov lag luam mus rau pej xeem zej zog, cov qauv ua rau tib neeg thoob plaws ntiaj teb tuaj. hais ib hom lus thiab dhau los ua tus qauv thoob ntiaj teb rau kev ua tau zoo, kev nyab xeeb thiab kev ntseeg siab tshaj plaws. "
Tus thawj connector txheem nyob rau hauv lub photovoltaic kev lag luam yog 2pfg 1161 launched los ntawm TÜV Rhine nyob rau hauv 2004. Nrog rau kev nruam innovation ntawm connector khoom thiab kev loj hlob ntawm kev ua lag luam thov, nws mas mus los ntawm DIN V VDE V 0126-3 (2006), en 50521 (2008) thiab en 50521: 2008 plus a1 (2012), thiab thaum kawg tsim IEC 62852 hauv 2014. Tam sim no, cov qauv siv tau hauv kev lag luam yog IEC 62852: 2014 ntxiv rau a1 (2020). Cov txheej txheem thoob ntiaj teb tau coj cov qauv rau kev lag luam thiab ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom hauv cov ntawv thov davhlau ya nyob twg.
Ntxiv rau cov qauv thoob ntiaj teb, ntau lub teb chaws lossis cheeb tsam kuj muaj cov qauv kev lag luam hauv zos, xws li UL 6703 hauv North America, dav hlau hauv Nyij Pooj, thiab gb/t 33765-2017 DC connectors rau terrestrial photovoltaic systems hauv Suav teb.
Connector iteration
During the life cycle of photovoltaic system (>25 xyoo), lub connector raws li lub zog transmitter yuav tsum muaj ib tug tsis tu ncua kev tiv thaiv kom tsis muaj zog poob, txwv tsis pub nws yuav zoo li ua rau lub zog poob. Nyob rau tib lub sijhawm, lub connector yuav tsum tau hloov mus rau ntau qhov chaw hnyav, xws li cua thiab nag, tshav kub, ntsev pos huab thiab huab cua hloov pauv.
Ua ntej xyoo 1996, photovoltaic cables feem ntau txuas nrog cov ntsia hlau terminals lossis splice kev sib txuas, tab sis txoj kev no tsis tuaj yeem ua tau raws li ib puag ncig thiab kev lag luam xav tau. Nyob rau hauv 1996, nyob rau hauv lub customized thov ntawm kawg cov neeg muas zaub, stobil launched ib tug tshiab plug-in connector raws li cov tub ntxhais technology ntawm hluav taws xob kev twb kev txuas, multilam - lub ntiaj teb no tus thawj photovoltaic connector MC3. Lub cev tseem ceeb ntawm MC3 txais cov khoom siv TPE (thermoplastic elastomer) thiab paub txog kev sib txuas ntawm lub cev los ntawm kev sib txhuam.
Nyob rau hauv 2002, stobil launched MC4 connector, uas tiag tiag paub "plug thiab ua si". Cov khoom siv insulating yog cov khoom siv tawv (pc / pa), thiab nws yooj yim rau kev sib sau thiab nruab rau ntawm qhov chaw hauv kev tsim. Tom qab MC4 tau teev tseg, nws tau lees paub sai los ntawm kev ua lag luam thiab maj mam dhau los ua tus qauv kev lag luam. Txhawm rau hloov mus rau qhov kev txhim kho ntawm qib voltage ntawm photovoltaic system, MC4 Evo 2 kuj tau los ua. Kev tiv thaiv kev tiv thaiv yog tsawg dua 0.2 milliohm, thiab qhov siab tshaj plaws nqa tam sim no yog 70A, uas ua tau raws li qhov xav tau ntawm 1500V photovoltaic system thiab cov lag luam loj loj.
Tib lub sijhawm, MC4 series connector yog thawj photovoltaic connector haum rau qhov kub thiab txias (IEC TS 63126: 2020 Theem 2) thiab qhov siab siab (mc44000 meters; MC4 Evo 25000 meters) tom qab dhau TÜV Rhein xeem.
Yav tom ntej tiam
Txawm hais tias tam sim no lossis yav tom ntej, hauv paus ntsiab lus, kev txhim kho ntawm cov khoom siv hluav taws xob photovoltaic yuav tsum tau cog lus los txhim kho kev ntseeg tau thiab sib xws ntawm cov khoom thiab txo kev siv hluav taws xob, txhawm rau pab txo qis kWh tus nqi hauv tag nrho lub neej voj voog ntawm photovoltaic fais fab mov. .
Shenqianping, tus thawj coj ntawm cov khoom thiab kev pabcuam kev pabcuam ntawm stouber (Hangzhou) hluav taws xob connector ua lag luam department, ntseeg hais tias yav tom ntej photovoltaic connectors yuav tsum tau ua raws li cov txheej txheem kev loj hlob ntawm photovoltaic modules (xws li ntau dua voltage thiab siab dua tam sim no), technological upgrading ntawm photovoltaic systems ( xws li cov kab hluav taws xob siab dua thiab cov kab hluav taws xob tsis yog photovoltaic), kev siv ntau yam tshwj xeeb ib puag ncig xwm txheej (xws li lub hiav txwv ntab fais fab chaw nres tsheb, chaw ua liaj ua teb thiab tsiaj txhu, chaw nres tsheb fais fab suab puam thiab BIPV) thiab kev ua haujlwm ntse thiab kev saib xyuas.
