Bokosi la High-Current Photovoltaic Junction Box Lakwaniritsa Mokwanira Zofunikira za 210 PV Module

Ndi kupanga kwakukulu kwa 166, 182, ndi 210 photovoltaic modules, makampani akupitiriza kukambirana za ubwino ndi kuipa kwa kusintha kwa kukula kwa silicon wafer.Cholinga cha zokambiranacho chimaphatikizapo magawo a magetsi ndi miyeso ya ma modules, kayendedwe, ndi zopangira zopangira.Inde, palinso zokambirana zina pa kudalirika ndi kusankha zinthu za photovoltaic junction mabokosi.Monga ogulitsa zinthu zomwe zimagwira ntchito yofufuza ndi kupanga ndi kupanga mabokosi ophatikizika kwa nthawi yayitali, timasanthula ubale womwe ulipo pakati pa mabokosi ophatikizika ndi zowotcha zazikulu za silicon ndi ma module amphamvu kwambiri potengera zinthu.

Mfundo Yogwira Ntchito ya Photovoltaic Junction Box

Ntchito yaikulu yabokosi la photovoltaic junctionndikutulutsa mphamvu yopangidwa ndi gawo la photovoltaic kupita kudera lakunja, kuphatikiza chipolopolo, diode, cholumikizira cha mc4, chingwe cha photovoltaic ndi zigawo zina, zomwe diode ndi chipangizo chachikulu.Pamene gawoli likugwira ntchito bwino, diode mu bokosi la PV mphambano ili mumsewu wotsekereza;pamene selo la module likutsekedwa kapena kuwonongeka, diode yodutsa imatsegulidwa kuti iteteze gawo lonse la photovoltaic.

Gome lomwe lili pamwambapa likuwonetsa magawo amagetsi amagetsi a 166, 182 ndi 210 ma module ndi masankhidwe apano a photovoltaic junction box of photovoltaic module fakitale.Ma module a module amawonetsa otsika kwambiri, ma voltage apamwamba komanso apamwamba komanso otsika motsatana.

Photovoltaic Junction Box ndi Diode

Zizindikiro zazikulu za bokosi lophatikizira la photovoltaic limaphatikizapo bokosi lophatikizika lomwe lidavotera panopa, diode yomwe idavotera pakali pano ndikuyimitsa magetsi, ndi zina zambiri, kutengera kapangidwe ka bokosi lolumikizirana komanso kusankha kwa ma diode.

Kawirikawiri, chivomerezo ndi kuyesa ma modules a photovoltaic ndi mabokosi ophatikizika amachokera pa: chiwerengero chamakono cha mabokosi ogwirizanitsa dzuwa ≥ 1.25 nthawi Isc posankha ndi kuyesa, ndipo malire ena adzasungidwa.M'malo ogwirira ntchito bwino, diode ya bokosi yolumikizira ili m'malo odulidwa.Mosasamala kanthu za 166 ndi 182 zigawo kapena zigawo 210, ma diode sadzachita kapena kutentha.Poyerekeza ndi zigawo 210, ma diode a mabokosi ophatikizika a 182 ndi 166 azitha kukhala ndi voliyumu ya High reverse bias.

Pamene malo otentha amapezeka mu photovoltaic module, diode idzapita patsogolo ndikupanga kutentha.Tengani gawo la 210 ndi bokosi lophatikizana la 25A mwachitsanzo, pamene zotuluka panopa Isc = 18.6A (panopa pamene gawo lenileni likugwira ntchito ndi Imp≈17.5A), kutentha kwapakati kuli pafupifupi 120 ° C.Ngakhale kuganizira mbali ya chilengedwe ndi kuwala kokwanira, pa nthawi ya 1.25 Isc (23.2A), kutentha kwapakati pa bokosi la photovoltaic panthawiyi ndi pafupifupi 160 ° C, yomwe ili yotsika kwambiri kuposa 200 ° C. Kutentha kumtunda kwa malire a IEC62790.Zoonadi, Isc ya ma modules 182 ndi 166 ndi yotsika pang'ono, ndipo bokosi lolumikizana lomwe lili ndi kasinthidwe komweko limakhala ndi mbadwo wochepa wa kutentha, ndipo mabokosi ophatikizira ali muchitetezo chogwira ntchito kotero kuti palibe chiopsezo.

Kusanthula pamwambapa ndikugwira ntchito kwa bokosi lolumikizana la photovoltaic pankhani ya malo otentha mu gawo la photovoltaic.Ponena za ma modules, mbalame kapena masamba akatsekereza malo otentha ndikutha msanga, kuthawa kwa diode kudzachitika.Chingwe cha module chidzabweretsa pompopompo reverse bias voltage ndi kutayikira kwapano ku diode, ndipo voteji yazingwe yapamwamba idzabweretsa zovuta zazikulu pabokosi lolumikizirana ndi diode.Kuchokera pamalingaliro a kapangidwe ka bokosi la PV, kapangidwe kake kabokosi koyenera, kuyika kosavuta kwa kutentha kwa diode ndikusankha bwino chip kumatha kuthetsa mavutowa.

Pamagawo awiri am'mbali ndi ma module a theka lachidutswa, popeza mbali iliyonse ya unit imalumikizidwa mofanana ndi mzake, monga momwe tawonetsera m'munsimu, pamene zotsatira za malo otentha ndi kuthawa kwa kutentha zimachitika, gawo lofanana likhoza kutsekedwa, ndi malire a chitetezo. kusungidwa ndi bokosi lolumikizira ndilokulirapo.Malinga ndi mawerengedwe, mwayi woti mbali zofananira, kutsogolo ndi kumbuyo kwa gawo limodzi la theka-cell amatsekedwa nthawi imodzi ndizochepa kwambiri, zomwe zimakhala za 1 gawo mu 10GW.Chifukwa chake, pansi pazikhalidwe zenizeni, ndizosatheka kukhala ndi bokosi lolumikizana likugwira ntchito modzaza, ndipo kudalirika kumatha kutsimikizika.

Photovoltaic zolumikizira ndi zingwe

Monga chimodzi mwa zigawo mphamvu kufala, ndicholumikizira cha photovoltaicali ndi udindo wolumikiza bwino malo opangira magetsi.Pakadali pano, zolumikizira zomwe zimagwiritsidwa ntchito kwambiri pamsika ndizokwera kuposa 30A, ndipo zochulukirapo zimatha kufika ku 55A, zomwe ndi zokwanira kukwaniritsa zofunikira zotumizira mphamvu zamagetsi zomwe zilipo kale.Zatsimikiziridwa kuti mu 55A module reverse reverse overload test ya photovoltaic connector yokhala ndi 41A yovomerezeka ya 41A kuchokera kwa wopanga, kutentha koyang'aniridwa ndi 76 ° C, komwe kumakhala kotsika kwambiri kuposa 105 ° C RTI mtengo wa zopangira. cha cholumikizira.Komabe, m'malo ogwiritsira ntchito kwambiri masiku ano, cholumikizira cholumikizira chiyeneranso kuyesa kupewa zovuta zomwe zingachitike monga kuchepa kwaposachedwa komwe kumachitika chifukwa cha kukana kwakukulu komweko komanso kutenthedwa kwa malo olumikizana nawo.Mayankho ogwira mtima, monga: kukhathamiritsa magwiridwe antchito a mphete ya kondakitala, kukonza mawonekedwe onse a cholumikizira, kuwongolera mtundu wa chingwe cholumikizira kumapeto kwa cholumikizira, ndikuwonjezera ukadaulo wa inshuwaransi iwiri pagawo lolumikizira.

Zazingwe za photovoltaic, chiwerengero cha zingwe zomwe zimagwirizana ndi EN kapena IEC (zingwe za 4mm2, zomwe zilipo panopa ndi 44A pamene malo ali pafupi ndi wina ndi mzake) ndi apamwamba kwambiri kuposa momwe amachitira bokosi la photovoltaic junction box, kotero palibe chifukwa chokhalira. nkhawa ndi kudalirika kwake.

PV Junction Box Manufacturing process ndi Market Overview

Ndi kusintha kosasunthika kwa mulingo wopangira komanso mphamvu zowongolera zamabokosi ophatikizika a photovoltaic, magwiridwe antchito ndi kudalirika kwa mabokosi ophatikizika atsimikiziridwa bwino, omwe amatha kukwaniritsa zofunikira zazitsulo zazikuluzikulu za silicon ndi zida zamphamvu kwambiri.

1. Popanga ndi kupanga bokosi la photovoltaic junction, njira zambiri zatsopano ndi matekinoloje atsopano omwe atsimikiziridwa m'magawo a semiconductor, galimoto, ndege, ndi zina zotero zimayambitsidwa, monga teknoloji yopangira ma module, kuwotcherera pafupipafupi kwapakati. ukadaulo, etc., kupititsa patsogolo magwiridwe antchito amagetsi ndi kutentha kwapang'onopang'ono luso lazinthu zamabokosi.

2. Mu PV panel junction bokosi kupanga ndondomeko, kuonjezera kafukufuku ndi chitukuko ndi ndalama za zipangizo zochita zokha akhoza kuonetsetsa processing kulondola, khalidwe, ndi ndondomeko controllability, ndi kukwaniritsa ndondomeko zochita zokha ndi khalidwe kulamulira zochita zokha.

3. Kutengera luso la kupanga bokosi la PV junction, yang'anani pakulimbikitsa kuwongolera kudalirika kwa kulumikizana pakati pa zida za bokosi lolumikizirana ndi kasamalidwe ka mfundo zazikuluzikulu zowongolera, monga kuwongolera kuchuluka kwa kuponderezana pamalo olumikizirana, pawiri inshuwalansi ndondomeko zofunika kuti tinning, ndi akupanga kuwotcherera ndondomeko ulamuliro , Corona mankhwala, ndi kuwunika magawo ofunika.

Kuphatikiza pa kuwongolera luso la opanga ma bokosi a photovoltaic, opanga zigawo ndi mabungwe a chipani chachitatu akuwongolera mosalekeza kuyesa, kuwunika ndi kuwongolera kwabwino kwa mabokosi ophatikizika ndi zigawo, zomwe zalimbikitsanso kuwongolera kwaukadaulo ndi luso la R&D. opanga mabokosi a junction.

Kuyambira theka loyamba la 2020, mabungwe aziphaso monga TUV apereka ziphaso za 25A ndi 30A junction box certification kwa ambiri opanga mabokosi a PV junction.Magulu a mabokosi akuluakulu amakono adutsa chivomerezo ndi kuyesedwa kwa mabungwe a chipani chachitatu, zomwe zalimbitsanso chidaliro cha opanga bokosi lamagulu ndi opanga ma module a photovoltaic.Ndi kutulutsidwa kwa mphamvu yopangira ma modules 182 ndi 210 akuluakulu a silicon wafer, mphamvu zopangira zopangira mabokosi akuluakulu amakono zidzakhazikitsidwa ndikukulitsidwa.

Mwachidule, magwiridwe antchito, kudalirika kotsimikizika ndi kuthekera kopanga mabokosi apamwamba amakono a photovoltaic ndi zigawo zake ndizokhwima, ndipo zimatha kukwaniritsa zofunikira zamitundu yosiyanasiyana yamitundu yayikulu ya silicon ndi zida zamphamvu kwambiri.
