Yintoni iSolar PV Combiner Box?

Indima yebhokisi ye-solar PV yokudibanisa kukudibanisa imveliso yeentambo ezininzi zelanga.Abaqhubi beentambo zomhlaba ngamnye kwi-terminal ye-fuse, kunye nesiphumo esivela kwigalelo le-fuse zidibaniswe kwi-conductor eyodwa edibanisa kwibhokisi yokudibanisa yelanga kunye ne-inverter.Nje ukuba unebhokisi yokudibanisa ye-DC kwiprojekthi yakho yelanga, kuhlala kukho ezinye izinto ezongezelelweyo ezifakwe kwibhokisi yokudibanisa, njenge.ukwahlula iiswitshi, izixhobo zokubeka iliso kunyeizixhobo zokuvala ngokukhawuleza.

Ibhokisi yokudibanisa i-solar DC iphinda idibanise amandla angenayo kwisondlo esikhulu esisasazwa kwii-PV inverters.Oku konga iindleko zabasebenzi kunye nezinto eziphathekayo ngokunciphisa ucingo.Iibhokisi zokudibanisa ze-DC zenzelwe ukubonelela ngokhuseleko olugqithisiweyo kunye nokugqithiswa kwe-overvoltage ukuphucula ukhuseleko kunye nokuthembeka kwe-inverter.

Ukuba iprojekthi ineentambo ezimbini okanye ezintathu kuphela, njengekhaya eliqhelekileyo, ibhokisi yokudibanisa intambo yelanga ayifuni.Endaweni yoko, kuya kufuneka udibanise imitya ngokuthe ngqo kwi-inverter.Iibhokisi zokudibanisa iintambo ze-PV ziyimfuneko kuphela kwiiprojekthi ezinkulu, ukusuka kwi-4 ukuya kwii-4,000 iintambo.Nangona kunjalo, iibhokisi zokudibanisa i-photovoltaic zineenzuzo kwiiprojekthi zabo bonke ubukhulu.Kwizicelo zokuhlala, iibhokisi zokudibanisa i-PV zinokuzisa inani elincinci leentambo kwindawo ephakathi ukuze kube lula ukufakwa, ukuqhawula kunye nokugcinwa.Kwizicelo zorhwebo, iibhokisi zokudibanisa zobukhulu obuhlukeneyo zihlala zisetyenziselwa ukudweba amandla kwizakhiwo ezingaqhelekanga kwiintlobo ezahlukeneyo zokwakha.Kwiiprojekthi zomgangatho womsebenzi, iibhokisi zokudibanisa zivumela abaqulunqi besayithi ukuba bakhulise amandla kwaye banciphise iindleko zempahla kunye nabasebenzi ngokusabalalisa ukudibanisa okudibeneyo.

Ibhokisi yokudibanisa iphaneli yelanga kufuneka ibekwe phakathi kweepaneli zelanga kunye ne-inverter.Inciphisa ilahleko yamandla xa ibekwe ngokufanelekileyo kuluhlu lwelanga.Indawo ibaluleke kakhulu, njengoko iibhokisi zokuhlanganisa ilanga kwiindawo ezingezizo ezona zilungileyo zingongeza kwiindleko ze-DC BOS ngenxa yombane kunye nelahleko yamandla, kwaye ngelixa iisenti ezimbalwa kuphela kwiwatt nganye, kubalulekile ukuyifumanisa.

Iibhokisi zeSolar PV zokudibanisa zifuna ukugcinwa okuncinci, kwaye okusingqongileyo kunye nokusetyenziswa rhoqo kufuneka kumisele inqanaba lokugcinwa.Luluvo oluhle ukuzijonga rhoqo ukuba zivuza okanye ziqhagamshelene.Ukuba ibhokisi yokudibanisa i-PV ifakwe ngokuchanekileyo, inokuqhubeka nokusebenza kubo bonke ubomi beprojekthi yelanga.

Umgangatho ngowona ngqalelo ubalulekileyo xa ukhetha ibhokisi ye-solar ye-DC, ngakumbi kuba yinto yokuqala yesixhobo esiqhagamshelwe kwimveliso yepaneli yelanga.Iibhokisi ze-DC zokuhlanganisa azibizi kakhulu xa zithelekiswa nezinye izixhobo kwiprojekthi yelanga, kodwa ibhokisi yokudibanisa engalunganga inokusilela ngeendlela ezimangalisayo, kubandakanya ukukhupha umlilo kunye nomsi.Zonke izixhobo kufuneka ziqinisekiswe ngumntu wesithathu ukuze zihambelane nomgangatho ofanelekileyo wolu hlobo lwezixhobo, i-UL1741, kwaye uqiniseke ukuba ukhetha ibhokisi yomhlanganisi welanga ehlangabezana neemfuno zobugcisa beprojekthi yakho.

Umkhwa omtsha wongeza ubude bentambo kunye nesixhumi sePV ekupheleni.Endaweni yokuba ikontraki yomba imingxunya kwibhokisi yokudibanisa uluhlu lwe-pv kwaye ifake izifakelo kwindawo, intambo yelanga inokufakwa kumzi-mveliso, ivumela isifakeli ukuba siqhagamshele ii-conductor eziphumayo kwibhokisi yokudibanisa uluhlu kusetyenziswa izihlanganisi ze-PV zokukhwelana.

Ngokuxhomekeke kwisicelo, iibhokisi ze-PV zokudibanisa iintambo zixhotyiswe ngezixhobo zokubeka iliso ezilinganisa ngoku, i-voltage kunye nobushushu ukuqinisekisa ukufumaneka kwentambo kunye nokwandisa ukuveliswa kwamandla.Ii-subsystems ezenziwe ngeebhokisi zokudibanisa intambo yelanga zinokumiselwa ngokwenani leentambo, i-voltage kunye nokulinganisa kwangoku.I-Slocable inikezela ngothotho olwahlukeneyo lweebhokisi zokuhlanganisa amandla elanga, nganye kuzo inikezelwe kwiimeko ezithile zofakelo ngolungelelwaniso oluqhelekileyo.

Izinto eziluncedo zeSolar PV Combiner Boxes:

1. Ibhokisi yokudibanisa i-solar ye-PV iphucula ukhuseleko lwepaneli yelanga kunye ne-PV yonke iplanti yamandla.
2. Iibhokisi zokuhlanganisa ifotovoltaic, ezikwabizwa ngokuba yi-DC switchboard, ziyifektri edityaniswe nezixhobo zokubeka iliso,Iifizi zeDC, izixhobo zokukhusela isantyakwaye ukhuphe iiswitshi njengeplagi kunye nesisombululo sokudlala.
