Slocable MC4 Solar Connectors for Harsh Environment

Pakutentha kozungulira 70 ° C kapena pamalo okwera pamwamba pa 2000 metres, zofunikira pakuyika magetsi zimasiyanasiyana kutengera nyengo.Malo ovuta kwambiri monga zipululu kapena mapiri angapereke mikhalidwe yabwino ya kuwala ndi malo opangira mphamvu zapamwamba za photovoltaic.Slocable MC4 cholumikizira dzuwambiri imatsimikiziridwa pazofunsira zotere.

Padziko lonse lapansi, ma photovoltaics amagwiritsidwanso ntchito kwambiri m'malo ovuta.Pafupifupi 35% ya dziko lapansi ndi chipululu, ndipo anthu ayamba kuganiza za momwe angagwiritsire ntchito bwino malowa, omwe alibe mphamvu zachuma komanso malo okhala ndi anthu ochepa, monga kumanga zomera za photovoltaic m'zipululu zotentha ndi zowuma. monga South America, Africa, Southern Europe ndi Middle East.

Kuonjezera apo, malo okwera kwambiri ndi malo abwino kwambiri opangira magetsi a dzuwa.Chifukwa cha kutalika kwake, magetsi opangira magetsi a photovoltaic amatha kupanga pafupifupi 50 % magetsi ochulukirapo kuposa m'malo osavuta.Kutentha kwambiri kwa dzuwa komanso nyengo yotentha nthawi zonse kumapangitsa kuti magetsi azikhala bwino kwambiri.Kuwonjezera pa madera a alpine ku Ulaya, ku Andes ku South America, magetsi ochulukirapo a photovoltaic akumangidwa pamwamba pa 2000 mamita pamwamba pa nyanja.

Miyezo Yachitetezo Pamalo Otentha Kwambiri

Poganizira kukula msanga kwa misika yotereyi, komiti yaukadaulo ya IEC TC82 yasiyanitsa mwatsatanetsatane zofunikira pazigawo zosiyanasiyana za kutentha kozungulira ndikukhazikitsa ma module a PV atsopano a zochitika zogwiritsa ntchito kutentha mpaka 70 ° C (98th percentile) chitetezo muyezo IEC 61730. -1.Pazogwiritsa ntchito kutentha kwambiri kozungulira monga m'malo achipululu, zofunikira za IEC TS 63126 zizigwira ntchito.

IEC TS 63126 imatchula zofunikira za kutentha kwa ma modules a photovoltaic ndi zigawo zake, monga mabokosi a photovoltaic junction ndi photovoltaic connectors, ndi magawo awiri osiyana kutentha.Magawo awiri a ma module a PV ndi awa:

Kutentha Kalasi 1: wofanana kapena wapamwamba kuposa 80°C (T98th)

Kutentha Kalasi 2: wofanana kapena wapamwamba kuposa 90°C (T98th).

Zofunikira zochepa pa kutentha kwapamwamba (ULT) kwa zolumikizira za photovoltaic ndi izi:

ULT ya zolumikizira zomwe zimagwiritsidwa ntchito pama module a PV a kalasi 1: 95 ° C osachepera

ULT ya zolumikizira zomwe zimagwiritsidwa ntchito pama module a PV a kalasi 2: 105 ° C osachepera

Zofunikira Zachitetezo Pamtunda Wapamwamba

Zofunikira pakugwirizanitsa zolumikizira zamagetsi mumiyezo yachitetezo chamagetsi nthawi zambiri zimapangidwira kuti zigwiritsidwe ntchito mpaka 2000 metres pamwamba pa nyanja.Pazogwiritsa ntchito pamalo okwera, zofunikira zovomerezeka ziyenera kusinthidwanso chifukwa kutsika kwa mpweya kumachepetsa kukana kwa kukhazikitsa kwamagetsi kuti kuthetsere mphamvu yamagetsi a flashover phenomena.Chifukwa chake, chilolezo chocheperako chiyenera kuchulukitsidwa ndi chowongolera patebulo la IEC 60664-1:2020, kapena kutsimikiziridwa ndi voteji yokwera kwambiri.

Kwa zaka zopitilira khumi, makina olumikizirana a Slocable PV DC akhala akudziwika chifukwa chodalirika komanso kukhazikika.Tsopano, yoyesedwa ndi kutsimikiziridwa ndi TÜV Rheinland, cholumikizira cha Slocable MC4 ndi chimodzi mwa zolumikizira za photovoltaic kuti zikwaniritse zofunikira zoyikira mu machitidwe a PV pogwiritsa ntchito gawo la kutentha kwa kalasi 2. Izi zikutanthauza kuti cholumikizira cha Slocable PV chayesedwa ndikutsimikiziridwa kuti chitha kugwiritsidwa ntchito. m'nyengo yozizira mpaka 105 ° C.
