Kusankhidwa kwa Solar PV Junction Box

Mfundo zazikuluzikulu zomwe ziyenera kuganiziridwa posankha bokosi la PV junction ziyenera kukhala zamakono za module.Imodzi ndiyo yomwe imagwira ntchito kwambiri ndipo ina ndi yanthawi yochepa.Zoonadi, mawonekedwe afupikitsa ndizomwe zimakhalapo zomwe module imatha kutulutsa.Malingana ndi nthawi yachidule, mphamvu yamagetsi ya bokosi yolumikizira iyenera kukhala ndi chitetezo chokulirapo.Ngati bokosi la PV junction la solar likuwerengedwa molingana ndi momwe mungagwiritsire ntchito pakali pano, chitetezo chimakhala chochepa.
Maziko asayansi osankhidwa akuyenera kutengera lamulo lakusintha kwamagetsi apano ndi magetsi a batire omwe amayenera kuchotsedwa ndi mphamvu ya kuwala.Muyenera kumvetsetsa malo omwe gawo lomwe mumapanga likugwiritsidwa ntchito, komanso momwe kuwala kulili kwakukulu m'derali, ndiyeno yerekezerani batri Kusintha kwamakono a chip ndi mphamvu ya kuwala, fufuzani zomwe zingatheke pakalipano, ndi kenako sankhani zomwe zidavotera pabokosi lolumikizirana.

1. Malingana ndi mphamvu ya photovoltaic module, 150w, 180w, 230w, kapena 310w?
2. Zofotokozera zina za zigawozo.
3. Magawo a diode, 10amp, 12amp, 15amp kapena 25amp?
4. Mfundo yofunika kwambiri, ndi kukula kotani kwa magetsi afupiafupi?Pakuyesa uku, kusankha kwa diode kumatengera izi:
Panopa (yaikulu ndi yabwino), kutentha kwakukulu kwa mphambano (kwaling'ono ndikwabwino), kukana kutentha (kwaling'ono ndikwabwino), kutsika kwamagetsi (kochepa ndikwabwinoko), voteji yowonongeka (nthawi zambiri 40V ndiyokwanira).

Split Junction Box

Pofika mu June 2018, bokosi lolumikizana ndi dzuwa pang'onopang'ono latenga nthambi kuchokera ku bokosi loyambirira lophatikizika mu 2015:bokosi logawanika, ndipo anapanga zotsatira pa Shanghai Photovoltaic Exhibition, yomwe ikuyimira kuthekera kwa mabokosi a PV m'tsogolomu Lowani mchitidwe wa mitundu yosiyanasiyana ndi chitukuko chofananira.
Mabokosi ophatikizika amodzi amagwiritsidwa ntchito makamaka pazinthu zachikhalidwe, ndipo mabokosi ophatikizika amtundu umodzi amagwiritsidwa ntchito makamaka pazinthu zatsopano zamagalasi apawiri.Poyerekeza ndi zakale, zotsirizirazi zitha kufunidwa kwambiri ndi msika komanso makasitomala tsopano.Pambuyo pake, ndikuyandikira kuzindikira bwino kuti mtengo wa mphamvu ya photovoltaic mphamvu yopangira magetsi ndi yochepa kuposa magetsi, zomwe zikutanthauza kuti mtengo wa mafakitale a photovoltaic udzachepetsedwa kwambiri, ndipo phindu la bokosi la photovoltaic junction lidzaphwanyidwa.Bokosi logawanika logawanika limabadwa ndi cholinga cha "kuchepetsa mtengo" ndipo limasinthidwa nthawi zonse.

Ubwino waBokosi Lopatukana Patatu

1. Kuchepetsa kwambiri kuchuluka kwa kudzaza ndi poto.Bokosi limodzi la bokosi ndi 3.7ml yokha, yomwe imachepetsa kwambiri mtengo wopanga, ndipo ubwino wa kukula kwazing'ono umapangitsa malo omangirira pa module kukhala ang'onoang'ono, kuwonjezera kuwala kwa gulu la photovoltaic, kuti malo opangira magetsi a photovoltaic atha kupeza. phindu lalikulu.

2. Konzani mawonekedwe a chipolopolo, ndipo zotsatira zotsutsana ndi ukalamba zimawonjezeka kwambiri.Mtundu watsopano wa bokosi logawanikana logawanika limagwiritsa ntchito ukadaulo waposachedwa wa kafukufuku ndi chitukuko, ndipo chipolopolo chake (bokosi lolumikizirana, cholumikizira) chili ndi mphamvu zotsutsa kukalamba komanso zosalowa madzi, ndipo zitha kugwiritsidwa ntchito nthawi zambiri pansi pazovuta zachilengedwe.

3. Mtunda wapakati wa bar ya basi yowongoleredwa ndi 6mm yokha, ndipo diode imatenga kuwotcherera kukana, kulumikizana kumakhala kotetezeka komanso kodalirika.

4. Bwino kutentha kutentha kwenikweni.Poyerekeza ndi bokosi lolowera, bokosi logawanika limapanga kutentha pang'ono ndipo limakhala ndi zotsatira zabwino zowonongeka.

5. Sungani kutalika kwa chingwe, ndipo muchepetsedi mtengo ndikuwonjezera mphamvu.Mapangidwe a magawo atatu amasinthanso njira yokhazikitsira ndi kutulutsa, kuti mabokosi ophatikizika abwino ndi oyipa akhazikike kumanzere ndi kumanja kwa gulu la photovoltaic, lomwe limafupikitsa kwambiri mtunda pakati pa gulu la batri ndi kulumikizana kwa dera. gulu la batri panthawi ya kukhazikitsa engineering.Njira yowongokayi sikuti imangochepetsa kutayika kwa chingwe, komanso imachepetsa kutayika kwa mphamvu yamagetsi chifukwa cha kutalika kwa mzere, ndikuwonjezera mphamvu ya module.

Pazonse, bokosi latsopano logawanika katatu likhoza kufotokozedwa ngati chitsanzo cha "zapamwamba komanso zotsika mtengo", ndipo zadutsa muyeso waposachedwa wa TUV (IEC62790).Kupititsa patsogolo bwino kwa bokosi logawanika kumayimira kuti China ili ndi malo abwino kwambiri pampikisano wampikisano wa grid parity photovoltaic.

Zowonjezera: Kusintha kwa Mabokosi a Solar PV Junction

Mabokosi ophatikizira a Solar PV akhala akugwira ntchito yofanana nthawi zonse, koma tsopano pamene mphamvu yotulutsa mphamvu ndi magetsi a solar panels akuwonjezeka, bokosi lamagetsi la solar liyenera kupititsa patsogolo luso loteteza mphamvu.

"Ntchito yaikulu ya bokosi lolumikizira imakhalabe yofanana, koma ma modules a PV akukhala amphamvu kwambiri," anatero Brian Mills, North American PV Product Manager ku Stäubli Electrical Connectors."Pamene ma module a PV akuchulukirachulukira, ma diode odutsa amayenera kugwira ntchito zambiri.Momwe amatengera mphamvu ndikuchotsa kutentha, kotero kutentha kwa ma diode kuyenera kuthana nawo.

Zosinthira zoziziritsa kuzizira zikulowa m'malo mwa ma diode achikhalidwe m'mabokosi ena a PV kuti achepetse kutentha kwakukulu kopangidwa ndi zotulutsa zapamwamba za PV.Pamene gulu la solar lamthunzi likufuna kutaya mphamvu mwachibadwa, ma diode ochiritsira amalepheretsa kuti izi zisachitike, koma zimapanga kutentha.Kusintha kozizira kodutsa kumagwira ntchito ngati kuyatsa / kuzimitsa, kutsegula dera pamene solar panel ikuyesera kuyamwa mphamvu, kuteteza kutentha.

"Bypass diode ndiukadaulo wazaka za m'ma 1950," adatero Mills."Ndizovuta komanso zodalirika, koma kutentha kwakhala kovutitsa nthawi zonse."Zosinthira zoziziritsa kuzizira zimathetsa vutoli, koma ndizokwera mtengo kwambiri kuposa ma diode, ndipo aliyense amafuna ma module a solar PV akhale otchipa momwe angathere.

Kuti apeze ndalama zambiri, eni ake ambiri a PV akutembenukira ku mapanelo a dzuwa.Ngakhale magetsi amapangidwa kutsogolo ndi kumbuyo kwa solar panel, mphamvu imatha kulowetsedwa kudzera m'bokosi lolumikizirana.Opanga bokosi la PV junction amayenera kupanga zatsopano ndi mapangidwe awo.

"Pa gulu la solar solar, muyenera kuyika bokosi la PV m'mphepete mwake momwe mungatsimikizire kuti msana ulibe mthunzi," adatero Rosenkranz."M'mphepete mwake, bokosi lolumikizira silingakhalenso lamakona anayi, liyenera kukhala laling'ono."

Kulumikizana kwa TE kumapereka mabokosi atatu ang'onoang'ono a SOLARLOK PV Edge junction ma modules a PV a bifacial, limodzi lililonse kumanzere, pakati, ndi kumtunda kumanja kwa gawoli, lomwe limagwiranso ntchito mofanana ndi bokosi lalikulu la makoswe.Stäubli ikupanga bokosi la PV lolumikizana kuti liyike m'mphepete mwa ma module awiri.

Kutchuka kofulumira kwa ma module a PV amitundu iwiri kumatanthauza kuti mapangidwe a bokosi la PV akuyenera kukwezedwa pakanthawi kochepa.Zosintha zina zadzidzidzi pamakina oyendera dzuwa zimaphatikizira kuzimitsa mwachangu komanso zinthu zosiyanasiyana zomwe zimafunidwa ndi National Electrical Code, ndipo mabokosi a PV junction akuyeneranso kupitilira.

Bokosi la Stäubli's PV-JB/MF multifunction junction bokosi limasinthidwa mwamakonda ndi mawonekedwe otseguka, kotero litha kukhala lokonzekera zosintha zamtsogolo, kuphatikiza ma optimizers onse kapena ma micro-inverters, ngati zida zawo zamagetsi zimakhala zazing'ono mokwanira.

TE Connectivity idayambitsanso bokosi lanzeru la PV lophatikizana lomwe limaphatikizira ma board ozungulira osindikizidwa (PCBs) kukhala mayankho a solar panel ndi kuyang'anira, kukhathamiritsa komanso kutseka mwachangu.

Opanga bokosi la PV junction akuganiziranso kuwonjezera ukadaulo wa inverter kumitundu yawo yamtsogolo.Mabokosi a mphambano onyalanyazidwa akukopa chidwi kwambiri.
