Wakupha wosawoneka wachitetezo cha siteshoni yamagetsi ya photovoltaic--Cholumikizira chosakanikirana choyikapo

Selo la dzuwa ndi chimodzi mwa zigawo zazikuluzikulu za magetsi a dzuwa, ndipo selo la dzuwa limatha kupanga magetsi pafupifupi 0.5-0.6 volts, omwe ndi otsika kwambiri kuposa magetsi omwe amafunikira kuti agwiritse ntchito.Kuti akwaniritse zofunikira zogwiritsira ntchito, maselo ambiri a dzuwa amafunika kumangidwa mu ma modules a dzuwa, ndipo ma modules angapo amapangidwa kuti akhale osakanikirana kudzera muzitsulo za photovoltaic kuti apeze magetsi ofunikira komanso amakono.Monga chimodzi mwa zigawozi, cholumikizira cha photovoltaic chimakhudzidwanso ndi zinthu monga malo ogwiritsira ntchito, chitetezo chogwiritsira ntchito, ndi moyo wautumiki.Chifukwa chake,cholumikizira chimafunika kuti chikhale chodalirika kwambiri.

Zojambula za Photovoltaic, monga chigawo cha ma modules a dzuwa, ziyenera kugwiritsidwa ntchito pansi pa zovuta zachilengedwe ndi kusintha kwakukulu kwa kutentha.Ngakhale kuti nyengo ya chilengedwe m'madera osiyanasiyana a dziko lapansi ndi yosiyana, komanso nyengo ya chilengedwe m'dera lomwelo imasiyanasiyana kwambiri, zotsatira za nyengo ya chilengedwe pa zipangizo ndi zinthu zikhoza kufotokozedwa mwachidule ndi zifukwa zinayi zazikulu: choyamba,kuwala kwa dzuwa, makamaka kuwala kwa ultraviolet.Zotsatira za zinthu za polima monga mapulasitiki ndi mphira;otsatidwa ndikutentha, pakati pa kutentha kwakukulu ndi kutsika kwa kutentha ndi kuyesa kwakukulu kwa zipangizo ndi zinthu;kuphatikiza apo,chinyezimonga mvula, matalala, chisanu, etc. ndi zowononga zina monga asidi mvula, ozoni, etc. Impact pa zipangizo.Komanso,cholumikizira chimayenera kukhala ndi chitetezo champhamvu chamagetsi, ndipo moyo wautumiki uyenera kukhala wopitilira zaka 25.Chifukwa chake, zofunikira pakuchita zolumikizira za photovoltaic ndi:

(1) Mapangidwe ake ndi otetezeka, odalirika komanso osavuta kugwiritsa ntchito;
(2) Mlozera wapamwamba kwambiri wa chilengedwe ndi nyengo;
(3) Zofunikira zolimba kwambiri;
(4) High magetsi chitetezo ntchito;
(5) Kudalirika kwakukulu.

Pankhani ya ma photovoltaic connectors, munthu ayenera kuganiza za Gulu la Stäubli, kumene cholumikizira choyamba cha photovoltaic chinabadwa.“MC4", mmodzi wa Stäubli'sMulti-Contactzonse zolumikizira magetsi, zakumana ndi zaka 12 kuyambira pomwe zidakhazikitsidwa mu 2002. Izi zakhala zodziwika bwino pamakampani, ngakhale zofananira ndi zolumikizira.

Shen Qianping, adamaliza maphunziro awo ku yunivesite ya Stuttgart, Germany ndi digiri ya master mu engineering yamagetsi.Iye wakhala akugwira ntchito ya photovoltaic kwa zaka zambiri ndipo ali ndi chidziwitso chochuluka pa nkhani ya kugwirizana kwa magetsi.Adalowa mu Gulu la Stäubli mu 2009 ngati mutu waukadaulo wothandizira dipatimenti yazinthu za photovoltaic.

Shen Qianping adati zolumikizira zosawoneka bwino za photovoltaic zitha kuyambitsazoopsa zamoto, makamaka pamakina ogawidwa padenga ndi ntchito za BIPV.Moto ukangochitika, kutayika kumakhala kwakukulu.Kumadzulo kwa China, kuli mphepo ndi mchenga wambiri, kusiyana kwa kutentha pakati pa usana ndi usiku ndi kwakukulu, ndipo mphamvu ya cheza ya ultraviolet ndiyokwera kwambiri.Mphepo ndi mchenga zidzakhudza kukonza kwa magetsi a photovoltaic.Zolumikizira zotsika ndizokalamba komanso zopunduka.Atatha kuswa, zimakhala zovuta kuwalowetsanso.Denga lakum'maŵa kwa China lili ndi zoziziritsa kukhosi, nsanja zoziziritsira, machumuni ndi zoipitsa zina, komanso nyengo yopopera mchere yamchere panyanja ndi ammonia opangidwa ndi malo opangira madzi oyipa, omwe angawononge dongosolo, ndiZolumikizira zosawoneka bwino zili ndi kutsika kwa dzimbiri kukana mchere ndi zamchere.

Kuphatikiza pa mtundu wa cholumikizira cha photovoltaic palokha, vuto lina lomwe lingayambitse zoopsa zobisika pakugwira ntchito kwa siteshoni yamagetsi ndikuphatikiza kuyika kwa zolumikizira zamitundu yosiyanasiyana.Pogwiritsa ntchito mapangidwe a photovoltaic system, nthawi zambiri zimakhala zofunikira kugula zolumikizira za photovoltaic padera kuti zizindikire kugwirizana kwa chingwe cha module ku bokosi lophatikizira.Izi ziphatikiza kulumikizana pakati pa cholumikizira chogulidwa ndi cholumikizira cha module, komanso chifukwa chaspecifications, kukula ndi kuloleranandi zinthu zina, zolumikizira zamitundu yosiyanasiyana sizingafanane bwino, ndikukana kukhudzana ndi kwakukulu komanso kosakhazikika, zomwe zingakhudze kwambiri chitetezo ndi mphamvu zamagetsi zamagetsi, ndipo zimakhala zovuta kupeza wopanga kuti azitsogolera ngozi zabwino.

Chithunzi chotsatirachi chikuwonetsa kukwera kwa kutentha ndi kukana komwe kumapezeka pambuyo pa TUV yosakanikirana ndikuyika zolumikizira zamitundu yosiyanasiyana, kenako kuyesedwa TC200 ndi DH1000.Zomwe zimatchedwa TC200 zimatanthawuza kuyesa kwa kutentha kwapamwamba ndi kotsika, mu kutentha kwa -35 ℃ mpaka +85 ℃, mayesero a 200 amachitika.Ndipo DH1000 imatanthawuza kuyesa kutentha kwachinyontho, komwe kumatenga maola 1000 pansi pa kutentha kwakukulu ndi kutentha kwakukulu.

 Kufananitsa Kutentha kwa cholumikizira (kumanzere: kukwera kwa kutentha kwa cholumikizira chomwecho; kumanja: kukwera kwa kutentha kwa zolumikizira zamitundu yosiyanasiyana)

Poyesa kukwera kwa kutentha, zolumikizira zamitundu yosiyanasiyana zimalumikizidwa wina ndi mzake, ndipo kukwera kwa kutentha mwachiwonekere ndikokulirapo kuposa kutentha kovomerezeka.

(Kukana kukana pansi pa kuyika kosakanikirana kwa zolumikizira zamitundu yosiyanasiyana)

Pakukana kukhudzana, ngati palibe zoyeserera zomwe zimagwiritsidwa ntchito, palibe vuto ndi zolumikizira zamitundu yosiyanasiyana kumalumikiza wina ndi mzake.Komabe, mu mayeso a gulu la D (mayeso osinthira zachilengedwe), zolumikizira za mtundu womwewo ndi mtundu zimasunga magwiridwe antchito, pomwemagwiridwe antchito a zolumikizira zamitundu yosiyanasiyana zimasiyana kwambiri.

Kwa zolumikizira zamitundu yosiyanasiyana zomwe zimalumikizana wina ndi mzake, mulingo wake wachitetezo cha IP ndiwovuta kutsimikizira.Chimodzi mwa zifukwa zazikulu ndi zimenezokulolerana kwa mitundu yosiyanasiyana ya zolumikizira ndizosiyana.

Ngakhale zolumikizira zamitundu yosiyanasiyana zitha kufananizidwa zikayikidwa, padzakhalabe zokoka, zopindika, ndi zakuthupi (zipolopolo zotsekera, mphete zosindikizira, ndi zina) zotsatira zoyipitsidwa.Izi sizingakwaniritse zofunikira ndipo zingayambitse mavuto pakuwunika.

Zotsatira za kuphatikiza kophatikiza zolumikizira zamitundu yosiyanasiyana:zingwe zotayirira;kuwonjezeka kwakukulu kwa kutentha kumakwera ndipo kumabweretsa chiopsezo cha moto;kupindika kwa cholumikizira kumabweretsa kusintha kwa mpweya ndi mtunda wa creepage, zomwe zimapangitsa kuti pakhale ngozi.

M'mafakitale amakono a photovoltaic, chodabwitsa cha inter-plugging ya zolumikizira zamitundu yosiyanasiyana zitha kuwonekabe.Kugwira ntchito molakwika kotereku sikungoyambitsa ngozi zaukadaulo komanso mikangano yamalamulo.Kuonjezera apo, chifukwa malamulo oyenerera akadali osakhala angwiro, makina opangira magetsi a photovoltaic adzakhala ndi udindo wa mavuto omwe amadza chifukwa cha kuyika pamodzi kwa mitundu yosiyanasiyana ya zolumikizira.

Pakadali pano, kuzindikira kwa "interplugging" (kapena "zogwirizana") zolumikizira kumangogwiritsidwa ntchito mndandanda womwewo wa zinthu zopangidwa ndi wopanga mtundu womwewo (ndi maziko ake).Ngakhale patakhala zosintha, maziko aliwonse adzadziwitsidwa kuti asinthe ma synchronous.Zotsatira zamsika zamakono za mayeso pa zolumikizira zamitundu yosiyanasiyana zomwe zimayikidwa molumikizana, zimangowonetsa momwe zitsanzo zoyeserera nthawi ino zilili.Komabe, chotsatirachi sichitifiketi chomwe chimatsimikizira kutsimikizika kwanthawi yayitali kwa zolumikizira za interplug.

Mwachiwonekere, kukana kukhudzana kwa zolumikizira zamitundu yosiyanasiyana kumakhala kosakhazikika, makamaka kukhazikika kwake kwanthawi yayitali kumakhala kovuta kutsimikizira, ndipo kutentha kumakhala kwakukulu, komwe kungayambitse moto poyipa kwambiri.

Pankhani iyi, mabungwe oyezetsa ovomerezeka a TUV ndi UL apereka mawu olembedwa kutisagwirizana ndi kugwiritsa ntchito zolumikizira zamitundu yosiyanasiyana.Makamaka ku Australia, ndikofunikira kuti tisalole machitidwe ophatikizira olumikizira.Choncho, cholumikizira chogulidwa mosiyana mu polojekitiyi chiyenera kukhala chofanana ndi cholumikizira pa chigawocho, kapena mndandanda womwewo wa mankhwala a wopanga yemweyo.

Kuonjezera apo, chojambulira cha photovoltaic pa gawoli nthawi zambiri chimayikidwa ndi wopanga bokosi lamagulu pogwiritsa ntchito zipangizo zamagetsi, ndipo polojekiti yoyendera yatha, kotero kuti khalidwe la unsembe ndilodalirika.Komabe, pamalo a polojekiti, kulumikizana pakati pa chingwe cha module ndi bokosi lophatikiza nthawi zambiri kumafuna kuyika kwamanja ndi ogwira ntchito.Malinga ndi kuyerekezera, osachepera 200 ma seti photovoltaic zolumikizira ayenera kuikidwa pamanja aliyense megawati photovoltaic dongosolo.Popeza mtundu waukadaulo wa gulu lamakono la uinjiniya wa photovoltaic system nthawi zambiri umakhala wotsika, zida zoyikira zomwe zimagwiritsidwa ntchito si zaukadaulo, ndipo palibe njira yabwino yowunikira uikidwe, kuyika kolumikizira kolumikizira pamalo a polojekiti nthawi zambiri kumakhala kosauka, komwe kumakhala mtundu. wa photovoltaic system Malo ofooka.

Chifukwa chomwe MC4 imayamikiridwa ndi msika ndikuti kuphatikiza pakupanga kwapamwamba, imaphatikizanso patent ya Stäubli:Multilam Technology.Ukadaulo wa Multilam makamaka umawonjezera chitsulo chapadera chowoneka ngati chingwe pakati pa zolumikizira zachimuna ndi chachikazi cha cholumikizira, m'malo mwazolumikizana zosagwirizana, kukulitsa kwambiri malo olumikizirana, kupanga mawonekedwe ofanana, komanso kukhala ndi mphamvu zonyamulira zamakono. , Kutayika kwa mphamvu ndi kukana kukhudzana kochepa, kukana kukhudzidwa, kukana kwa dzimbiri ndi kukana kutentha kwapamwamba, ndipo kumatha kusunga ntchitoyi kwa nthawi yaitali.

Zolumikizira za Photovoltaic ndizofunikira kwambiri pakulumikizana kwamkati kwamagetsi opangira mphamvu ya photovoltaic, osati kuchuluka kokha, komanso kuphatikiza zigawo zina.Chifukwa cha khalidwe la mankhwala palokha ndi khalidwe la unsembe, poyerekeza ndi zigawo zina, photovoltaic zolumikizira ndi gwero pafupipafupi zolephera dongosolo, ndipo zimakhudza kwambiri mphamvu mphamvu mphamvu ndi phindu chuma dongosolo lonse.Chifukwa chake,chojambulira cha photovoltaic chosankhidwa chiyenera kukhala chochepa kwambiri chokhudzana ndi kukhudzana, ndipo chikhoza kukhalabe chotsutsana chochepa kwa nthawi yaitali.Mwachitsanzo, aSlocable mc4 cholumikiziraali ndi kukana kukhudzana kokha 0.5mΩ ndipo akhoza kukhala otsika kukhudzana kukana kwa nthawi yaitali.
