Kutanthauzira Kwatsatanetsatane: Zolumikizira Zambiri za MC4

MC4 si yachilendo kwa akatswiri a photovoltaic, pafupifupi yakhala yofanana ndi ma photovoltaic connectors.Thecholumikizira cha MC4 cholumikizira ambiriangapezeke pazigawo zofunika za photovoltaic mphamvu zopangira mphamvu monga ma modules, mabokosi ophatikizira ndi ma inverters, ndipo ali ndi udindo wogwirizanitsa bwino malo opangira magetsi.

Pofika kumapeto kwa chaka cha 2015, mphamvu yaku China yowonjezeredwa yamagetsi inali 43.18GW, yomwe inali yoyamba padziko lonse lapansi.Kuwerengera pamaziko a pafupifupi 4,200 ya zolumikizira photovoltaic zomwe zimagwiritsidwa ntchito mu 1MW, pakali pano pali pafupifupi 180 miliyoni zolumikizira zomwe zidayikidwa ku China.Kuyang'ana pachiwopsezo, zikutanthauza kuti pali ziwopsezo zosachepera 180 miliyoni zomwe zikuyenera kuyang'aniridwa ndi eni malo osiyanasiyana amagetsi.

Komabe, kachigawo kakang’ono kameneka kamakhala kosaiwalika panthawi yokonza, kumanga, kugwira ntchito ndi kukonza malo opangira magetsi.Chifukwa chake chikugwirizana kwambiri ndi kumvetsetsa kwa aliyense za MC4.

Mwina ndi nthawi yoti mudziwenso cholumikizira cha MC4 cholumikizana ndi anthu ambiri.

Mbiri yachidule ya zolumikizira dzuwa

Kwa zolumikizira zambiri za MC4, 1996 ndi 2002 ndi zaka ziwiri zofunika kwambiri.Mfundo ziwirizi panthawiyi zimagwirizananso ndi mfundo zazikulu za chitukuko cha photovoltaic industry.Ngakhale kuti MC4 yolumikizana ndi ma multicontact sinatsagana ndi mafakitale a photovoltaic, mawonekedwe ake alimbikitsa kwambiri kuwonjezereka kwachangu kwa makhazikitsidwe a photovoltaic.

Chaka cha 1996 chisanafike, zingwe za photovoltaic zidalumikizidwa ndi ma screw terminals kapena ma splice.Chifukwa cha kuchuluka kwa ma photovoltaic systems omwe amaikidwa, makampaniwa ali ndi zofuna zowonjezereka zowonjezera, zotetezeka komanso zosavuta kugwiritsa ntchito njira zolumikizirana.

        Chifukwa chakuti photovoltaic system imayang'aniridwa ndi mphepo, mvula, dzuwa lotentha komanso kutentha kwakukulu kwa nthawi yaitali, cholumikizira cha dzuwa chiyenera kukhala chogwirizana ndi malo ovutawa.Ziyenera kukhala zosatetezedwa ndi madzi, kutentha kwapamwamba komanso kutentha kwa nyengo ku kuwala kwa ultraviolet, komanso kuteteza kukhudza, kunyamula mphamvu zamakono komanso kuchita bwino kwambiri.Panthawi imodzimodziyo, kukana kukhudzana kochepa ndikofunikanso kuganizira.Zonsezi ziyenera kudutsa mumayendedwe onse a photovoltaic system, osachepera zaka 20.

Mu 1996, kutengera malo ogwiritsira ntchitowa ndi zofuna za msika, mtundu watsopano wa cholumikizira cholumikizira chidayamba.Ichi ndiye cholumikizira choyamba padziko lonse lapansi cha photovoltaic-MC3.Woyambitsa wake ndi kampani yaku Swiss Multi-Contact (mu 2002, yomwe idaphatikizidwa ndi Stäubli Gulu ngati cholumikizira magetsi), MC ndiye chidule cha mtundu, ndipo 3 ndi kukula kwa mainchesi achitsulo.Thupi lalikulu la MC3 limapangidwa ndi zinthu za TPE (thermoplastic elastomer), ndipo kulumikizana kwakuthupi kumatheka chifukwa cha mgwirizano wosagwirizana.Chofunika kwambiri, MC3 imagwiritsa ntchito ukadaulo wa MULTILAM pamakina ake olumikizirana kuti zitsimikizire kukhazikika kwa kulumikizanako.Pambuyo pake, ambiri opanga zolumikizira akutsanzira ukadaulo wa MULTILAM.

Mu 2002, kubadwa kwa cholumikizira cha MC4 cholumikizana ndi anthu ambiri kumatanthauziranso cholumikizira cha photovoltaic, chomwe chinazindikiradi "pulagi ndi kusewera".Zida zotetezera zimagwiritsa ntchito PC/PA, ndipo mapangidwe ake ndi osavuta kusonkhanitsa ndikuyika pamalowo.Pambuyo pa MC4 yolumikizana ndi anthu ambiri idabwera pamsika, idadziwika mwachangu pamsika ndipo pang'onopang'ono idakhala muyezo wa zolumikizira za photovoltaic.Opanga ambiri amatcha zolumikizira zawo "× × MC4".Ngati mungasaka MC4 ku Alibaba, mutha kupeza pafupifupi 44,000 zofananira, zomwe zikuwonetsa kukopa kwa msika kwa MC4.

MC4 yakhazikitsa motsatizana mndandanda wa MC4-Evo2 ndi MC4-Evo3 pomwe kufunikira kwa msika kukusintha.Zolumikizira zotsatizana za MC4 zimatha kukwaniritsa zosowa za makasitomala pamakina a 1500V photovoltaic.

MC4 ndi "MC4-ngati"

Zolumikizira zambiri za MC4 zimagawidwa kukhala ma waya komanso malekezero a board.Mwanthawi zonse, MC4 yotchulidwa ndi aliyense imayimira ma waya.MC4 imakhala ndi magawo awiri: zitsulo ndi zida zotetezera.

Monga tanena kale, MC ndiye chidule cha Multi-Contact, ndipo 4 ndi kukula kwa mainchesi achitsulo.Choncho, pamsika wa photovoltaic connector, ambiri otchedwa MC4 amafunika kufotokozedwanso, ndipo akhoza kutchedwa "MC4-like".

Kupatulapo kusiyana kwa maonekedwe (monga mawonekedwe/logo, ndi zina zotero), kusiyana kwakukulu pakati pa MC4 ndi "MC4-like" ndiko kugwiritsa ntchito luso la MULTILAM.Tekinoloje ya MULTILAM ili ndi kukhazikika kwa nthawi yayitali, yomwe imatha kutsimikizira kuti cholumikiziracho chimakhalabe cholumikizira chocheperako nthawi yonse ya moyo wa photovoltaic system.

"MC4-monga", pazifukwa za msika, amati akugwirizana ndi MC4.Ngakhale zikuwoneka kuti kulumikizana kwatha, chiopsezo chobisika chachitetezo chachitika kale.Zolumikizira za opanga osiyanasiyana sizigwirizana muzofotokozera, miyeso ndi kulolerana, kotero sizingafanane ndi 100%.Mukalowetsana mokakamiza, zingayambitse kukwera kwa kutentha, kusintha kwa kukana, ndi mavuto omwe muyeso wa IP sangatsimikizidwe, zomwe zingakhudze kwambiri mphamvu yopangira mphamvu ndi chitetezo cha zotsutsa.

Chachikulu ndichakuti ngati pali vuto, ndiye kuti mutha kuyambitsa mikangano yamalamulo.Popeza kuti malamulo ndi malamulo oyenerera sali angwiro, udindo wamavuto omwe amabwera chifukwa cha kuyika pamodzi ukhoza kunyamulidwa ndi woyikira magetsi.

Chifukwa chake, onse a TüV/UL ndi Multi-Contact apereka chiganizo choletsa kuyika kwa zolumikizira kuchokera kwa opanga osiyanasiyana.

Zowopsa zaukadaulo za Multi-Contact MC4 Connectors

Poyesa, kupanga, kugula, kumanga, kumanga ndi kuyendetsa ndi kukonza magetsi a photovoltaic, pali zoopsa zosadziwika (ndondomeko / teknoloji / chilengedwe / malamulo, etc.).Kulamulira kosayenera kudzakhudza ndalama za photovoltaic systems.

Kufikira kutizolumikizira photovoltaicnkhawa, zoopsa zaukadaulo zikuphatikizidwa mumtundu, kugwiritsa ntchito, kukhazikitsa, ndikugwiritsa ntchito ndi kukonza.

Ziyenera kunenedwa kuti chifukwa chomwe chimayambitsa kulephera kwa cholumikizira cha PV ndi moto ndikuti: pakuyenda kwaposachedwa, kukana kolumikizana kwa cholumikizira kumawonjezeka, komwe kumabweretsa kuwonjezeka kwa kutentha, komwe kumapitilira kutentha. mitundu yomwe chipolopolo cha pulasitiki ndi zitsulo zimatha kupirira.
