Wopha Zomera za Mphamvu za Photovoltaic-DC Arc

Chifukwa cha zofunikira za kusalowerera ndale kwa carbon ndi kukwera pamwamba pa carbon, makampani atsopano a mphamvu tsopano akutchuka kwambiri.Aliyense akugwirizana kwambiri ndi malo opangira magetsi a photovoltaic, ndipo anthu ambiri akulowa mu makampani a photovoltaic.Komabe, kuchuluka kwa anthu omwe akuchita nawo ntchitoyi ndi kosagwirizana, ndipo anthu ambiri salabadira ma arcs a DC, zomwe zimapangitsa kuti pakhale ngozi zambiri.

Arc ndi mtundu wazinthu zotulutsa mpweya.Kuthetheka komwe kumachitika nthawi yomweyo komwe kumadutsa m'malo oteteza, monga mpweya, kumatchedwa arc.Zonse zachindunji komanso zosinthika zomwe zikupanga ma arcs.Nthawi zina tikamangirira socket, timawona zowala, zomwe ndi AC arc.Mu dongosolo la DC, arc yotereyi yomwe imayambitsidwa ndi chingwe cha cell cha photovoltaic imatchedwa DC arc.Mosiyana ndi zimenezi, machitidwe a DC amatha kupanga ma arcs kusiyana ndi machitidwe a AC, ndipo pamene arc imachitika, zimakhala zovuta kuzimitsa arc.

Mu malo opangira magetsi a photovoltaic, mapanelo a photovoltaic amatulutsa magetsi a DC, omwe amasinthidwa kukhala magetsi a AC pokhapokha atadutsa pa photovoltaic inverter.Kuthamanga kwa mapanelo a PV ndi okwera kwambiri, kuchokera ku ma volts mazana angapo mpaka kufika pa 1500 V. Ndipotu, makumi angapo a volts ndi okwanira kupanga DC arc, yomwe imatha kutulutsa kutentha kwa madigiri a 4200.Pamene mapanelo anayi a photovoltaic alumikizidwa palimodzi, magetsi ambiri amafika pafupifupi 120 volts.Kulumikizana kwabwino ndi koipa kwa mawaya nthawi yomweyo kumatulutsa arc ya DC, ndipo m'masekondi ochepa chabe, kutentha kwakukulu kumapangitsa kuti chingwe cha DC chamkuwa chisungunuke nthawi yomweyo ndikusanduka madontho amkuwa pansi.Malo osungunuka a mkuwa ndi madigiri 1083, mkuwa wosungunula ngati akudontha ku denga lamatabwa la zotsatira za nyumba zomwe sizingaganizidwe, zomwe zingayambitse moto, zina mwa moto wa nyumba ya ku Ulaya ndi chifukwa cha denga la magetsi a photovoltaic DC arc chifukwa. .Choncho, chitetezo cha DC arc cha zomera zamphamvu za photovoltaic ndizofunikira kwambiri.

Ndiye, n'chifukwa chiyani malo opangira magetsi a photovoltaic amapanga DC arc?Zifukwa zazikulu zomwe zimachitika kwa DC arc ndi: choyimira kapena cholumikizira fusesi sichimapanikizidwa, bawuti ya basi siimangirizidwa, kulumikizana ndi okosijeni, kutsekemera kwa waya kumachepetsedwa, kutsekereza kwa zida kumakhala kolakwika, ndi zina zotero.

Kodi zoopsa za DC arc kumagetsi a photovoltaic ndi ziti?Choyamba ndi kuwonongeka kwa zipangizo.Mabokosi ophatikizira, makabati a DC, zigawo za batire, zolumikizira, mabokosi ophatikizika, ndi zina zambiri atenthedwa.Chachiwiri ndi kutaya mphamvu.Kulephera kulikonse kudzachititsa kuti magetsi azichepa kapena ayi.Chachitatu ndi ngozi zachitetezo.Moto ukhoza kuwononga chitetezo chaumwini ndi katundu.

Kodi pali mwayi wotani woti ma arc amagetsi apangidwe pamalo opangira magetsi a PV?Tengani malo opangira magetsi a 10MW mwachitsanzo, pali zolumikizira bokosi zolumikizirana pafupifupi 80,000 ndi midadada 4,000, kuphatikiza zolumikizira zamkati zamabatire, nduna ya DC ndi ma inverter amkati, zonse zikuwonjezera mpaka 84,000, kotero ngati mwayi wolephera ndi 1 mu 10,000, pali 8 mwa iwo, kotero kuti mwayi wopezeka ndi wochuluka kwambiri.

Momwe Mungapewere DC Arc mu Photovoltaic Power Station?

Choyamba, onetsetsani kuti mukugwiritsa ntchito mankhwala okhazikika komanso oyenerera, osati zabodza komanso zopanda pake.Monga Slocable'smc4 inline fuse cholumikizirandibokosi logawanika.
Kachiwiri, chiwerengero cha node chiyenera kuchepetsedwa momwe zingathere.
Chachitatu, ogwira ntchito yomanga ayenera kugwiritsa ntchito zida zaukatswiri ndipo ayenera kuphunzitsidwa ndi kuphunzitsidwa mwaluso ndi mayeso asanawalembe ntchito.
Chachinayi, malo opangira magetsi atayikidwa, kuyang'anira koyenera kuyenera kuchitidwa.
Chachisanu, payenera kukhala zida zodziwikiratu zofananira, monga sensor iyi ya DC arc, iwo amawopsa ndikudula dera akangozindikira DC arc kuti athetse zoopsa zobisika.
Chachisanu ndi chimodzi, payenera kukhala nsanja yowunikira mphamvu kuti iwonetsere zonse zomwe zikugwira ntchito munthawi yeniyeni, kotero kuti zoopsa zobisika zikapezeka, ogwira ntchito angathe kudziwitsidwa nthawi yomweyo kuti athane nazo.

M'malo mwake, DC arc si yoyipa.Malingana ngati mudziwa njira yolondola ndikugwiritsa ntchito njira zotsutsana ndi sayansi, mutha kupewa ndikuthana nazo.Monga mphamvu ya AC kunyumba, chitetezo chimatsimikizika kwathunthu.Kupyolera mu njira zamakono zamakono, vuto la DC arc kupewa ndi kulamulira likhoza kuthetsedwa pamtengo wotsika.
