Umbulali we-Photovoltaic Power Plants-DC Arc

Ngenxa yeemfuno zokungathathi hlangothi kwekhabhoni kunye nokunyuka kwekhabhoni, ishishini elitsha lamandla ngoku lithandwa kakhulu.Wonke umntu uyavumelana ngakumbi kunye nezikhululo zamandla e-photovoltaic, kwaye abantu abaninzi bangena kwishishini le-photovoltaic.Nangona kunjalo, inqanaba labantu ababandakanyekayo kweli shishini alilingani, kwaye abantu abaninzi abahoyi ingqalelo kwi-DC arcs, ekhokelela kwinani elikhulu leengozi.

I-Arc luhlobo oluthile lokukhutshwa kwegesi.Intlantsi ekhawulezileyo eveliswa kukudlula kwangoku kwindawo ethile yokugquma, efana nomoya, ibizwa ngokuba yi-arc.Zombini i-arcs yangoku kunye ne-alternating yangoku yokuvelisa.Ngamanye amaxesha xa siplaga kwisokethi, siya kubona iintlantsi, eziyi-AC arc.Kwinkqubo ye-DC, i-arc enjalo ebangelwa intambo ye-photovoltaic ebizwa ngokuba yi-DC arc.Ngokwahlukileyo, iinkqubo ze-DC ziyakwazi ukuvelisa ii-arcs kuneenkqubo ze-AC, kwaye emva kokuba i-arc yenzeke, kunzima kakhulu ukucima i-arc.

Kwisikhululo samandla e-photovoltaic, iipaneli ze-photovoltaic zikhupha umbane we-DC, oguqulwa ube ngumbane we-AC kuphela emva kokudlula kwi-inverter ye-photovoltaic.Umbane weepaneli zePV ziphezulu kakhulu, ukusuka kumakhulu ambalwa ukuya kwi-1500 V. Enyanisweni, ii-volts ezimbalwa zanele ukuvelisa i-DC arc, enokuvelisa ukushisa okuphezulu ukuya kuma-4200 degrees.Xa iipaneli ezine ze-photovoltaic ziboshwe kunye, i-voltage ngokubanzi iya kufikelela malunga ne-120 volts.Uqhagamshelo olulungileyo nolungalunganga lweengcingo ngoko nangoko luvelisa i-arc ye-DC, kwaye kwimizuzwana nje embalwa, ubushushu obuphezulu buvumela intambo ye-DC yobhedu ukuba inyibilike ngoko nangoko kwaye ijike ibe ngamathontsi obhedu emhlabeni.Indawo yokunyibilika kobhedu yi-1083 degrees, ubhedu olutyhidiweyo ukuba luthontsiza kuphahla oluninzi lwamaplanga lweziphumo ze-villa azinakucingelwa, kusenokwenzeka ukuba kubangele umlilo, ezinye ze-villa zomlilo zaseYurophu zibangelwa uphahla lwesityalo samandla e-photovoltaic DC arc yabangela. .Ngoko ke, ukukhuselwa kwe-arc ye-DC yezityalo zamandla e-photovoltaic kubaluleke kakhulu.

Ngoko, kutheni isikhululo samandla e-photovoltaic sivelisa i-DC arc?Izizathu eziphambili zokuvela kwe-arc ye-DC zezi: i-terminal okanye uxhulumaniso lwe-fuse alunyanzelwanga, i-bolt ye-busbar ayiqiniswanga, ukudibanisa i-oxidized, i-insulation ye-wire iyancitshiswa, i-insulation ye-insulation inesiphako, njalo njalo.

Zeziphi iingozi zeDC arc kwizityalo zamandla ephotovoltaic?Eyokuqala ngumonakalo kwisixhobo.Iibhokisi zokudibanisa, iikhabhathi zeDC, iinxalenye zepaneli yebhetri, izihlanganisi, iibhokisi zokuhlangana, njl.njl.Okwesibini kukulahlekelwa kwamandla.Nakuphi na ukusilela kuya kubangela ukuveliswa kwamandla amancinci okanye kungabikho.Eyesithathu ziingozi zokhuseleko.Imililo inokubeka emngciphekweni ukhuseleko lomntu kunye nempahla.

Yintoni enokwenzeka ukuba i-arc yombane yenziwe kwisikhululo samandla sePV?Thatha isikhululo samandla esili-10MW umzekelo, kukho malunga ne-80,000 yeziqhagamshelo zeebhokisi ezidityanisiweyo kunye neebhloko ze-terminal ezingama-4,000, kunye namalungu angaphakathi eweld yeepaneli zebhetri, ikhabhinethi yeDC kunye neendawo zangaphakathi ze-inverter, zonke zongeza ukuya kuthi ga kwi-84,000, ngoko ke. ukuba amathuba okungaphumeleli yi-1 kwi-10,000, kukho i-8 kubo, ngoko ke amathuba okuba kwenzeke kuphezulu kakhulu.

Indlela yokuphepha i-DC Arc kwiSikhululo saMandla sePhotovoltaic?

Okokuqala, qiniseka ukuba usebenzisa iimveliso eziqhelekileyo kunye nezifanelekileyo, kungekhona iimveliso zomgunyathi kunye neemveliso ezinqabileyo.Ezinje ngeSlocable'smc4 umdibaniso wefuse ongaphakathikwayeibhokisi yesiphambuka.
Okwesibini, inani lee-nodes kufuneka lincitshiswe kangangoko kunokwenzeka.
Okwesithathu, abasebenzi bokwakha bafanele basebenzise izixhobo ezichubekileyo yaye bafanele baqeqeshwe baze baphumelele ngoqeqesho noviwo loqeqesho ngaphambi kokuba baqeshwe.
Okwesine, emva kokufakwa kwesikhululo samandla, uhlolo olufanelekileyo kufuneka lwenziwe.
Okwesihlanu, kufuneka kubekho izixhobo zokufumanisa ezihambelanayo, ezifana nale DC inzwa yokubona i-arc, baya kwenza i-alamu kwaye bayinqumle isiphaluka xa bebona i-DC arc ukuphelisa iingozi ezifihliweyo.
Okwesithandathu, kufuneka kubekho iqonga lokubeka iliso lamandla ukubeka iliso kuyo yonke idatha yokusebenza ngexesha langempela, ukuze xa iingozi ezifihliweyo zifunyenwe, abasebenzi banokwaziswa ngokukhawuleza ukuba bajongane nazo.

Ngapha koko, i-DC arc ayibi.Logama nje usazi kakuhle indlela echanekileyo kwaye usebenzisa iindlela zokuchasa zesayensi, unokuthintela ngempumelelo kwaye ujongane nayo.Njengamandla e-AC ekhaya, ukhuseleko luqinisekisiwe ngokupheleleyo.Ngokusebenzisa iindlela zobugcisa ezifanelekileyo, ingxaki yothintelo nolawulo lwe-arc ye-DC ingasonjululwa ngexabiso eliphantsi.
