Liyini Ibhokisi le-Solar PV Combiner?

Indima yebhokisi lesihlanganisi se-solar PV ukuhlanganisa ukukhishwa kwezintambo eziningana zelanga.Amakhondakta ochungechunge ngalunye ahlala kutheminali ye-fuse, kanye nokuphumayo okuvela kokokufaka kwe-fuse kuhlanganiswa kube umqhubi oyedwa oxhuma ebhokisini lesihlanganisi selanga kanye ne-inverter.Uma usunebhokisi lokuhlanganisa i-DC kuphrojekthi yakho yelanga, kuvame ukuba nezinye izici ezengeziwe ezifakwe ebhokisini lesihlanganisi, njengokuthiukuhlukanisa amaswishi, imishini yokuqapha kanyeimishini yokuvala shaqa ngokushesha.

Ibhokisi lokuhlanganisa i-solar DC liphinde lihlanganise amandla angenayo kube okuphakelayo okuyinhloko okusatshalaliswa kuma-inverter e-PV.Lokhu konga izindleko zabasebenzi kanye nempahla ngokunciphisa ucingo.Amabhokisi okuhlanganisa e-DC aklanyelwe ukuhlinzeka ngokuvikelwa kwe-overcurrent kanye ne-overvoltage ukuze kuthuthukiswe ukuvikeleka nokuthembeka kwe-inverter.

Uma iphrojekthi inezintambo ezimbili noma ezintathu kuphela, njengekhaya elivamile, ibhokisi lokuhlanganisa intambo yelanga alidingeki.Kunalokho, uzodinga ukuxhuma izintambo ngokuqondile ku-inverter.Amabhokisi okuhlanganisa izintambo ze-PV adingeka kuphela kumaphrojekthi amakhulu, kusukela kuzintambo ezingu-4 kuye kwezingu-4,000.Noma kunjalo, amabhokisi okuhlanganisa ama-photovoltaic anezinzuzo kumaphrojekthi awo wonke amasayizi.Kuzinhlelo zokusebenza zokuhlala, amabhokisi okuhlanganisa i-PV angaletha inombolo encane yezintambo endaweni emaphakathi ukuze kufakwe kalula, ukunqanyulwa nokunakekelwa.Kuzinhlelo zokusebenza zezentengiselwano, amabhokisi okuhlanganisa amasayizi ahlukene avame ukusetshenziselwa ukudweba amandla kusuka ezakhiweni ezingezona ezejwayelekile ezinhlotsheni ezahlukene zesakhiwo.Kumaphrojekthi esikali sokusetshenziswa, amabhokisi okuhlanganisa avumela abaklami besayithi ukuthi bakhulise amandla futhi banciphise izindleko zempahla nezabasebenzi ngokusabalalisa ukuxhumana okuhlanganisiwe.

Ibhokisi lokuhlanganisa iphaneli yelanga kufanele libe phakathi kwamaphaneli elanga kanye ne-inverter.Ikhawulela ukulahleka kwamandla uma ibekwe kahle kuhlelo lwelanga.Indawo ibaluleke kakhulu, njengoba amabhokisi e-solar esihlanganisi ezindaweni ezingafanelekile angangeza ezindlekweni ze-DC BOS ngenxa yokulahleka kukagesi namandla, futhi nakuba kungamasenti ambalwa kuphela nge-watt ngayinye, kubalulekile ukukuthola.

Amabhokisi okuhlanganisa i-Solar PV adinga ukulungiswa okuncane, futhi imvelo kanye nemvamisa yokusetshenziswa kufanele kunqume izinga lokugcinwa.Kungumqondo omuhle ukuwahlola njalo ukuthi awavuzi yini noma awaxhumekile.Uma ibhokisi lokuhlanganisa le-PV lifakwe ngendlela efanele, lingaqhubeka nokusebenza kukho konke ukuphila kwephrojekthi yelanga.

Ikhwalithi iwukucatshangelwa okubaluleke kakhulu lapho ukhetha ibhokisi lokuhlanganisa ilanga le-DC, ikakhulukazi njengoba liwucezu lokuqala lwemishini exhunywe ekuphumeni kwephaneli yelanga.Amabhokisi e-DC awabizi uma kuqhathaniswa nezinye izinto zokusebenza kuphrojekthi yelanga, kodwa ibhokisi lesihlanganisi elingalungile lingahluleka ngezindlela ezimangazayo, okuhlanganisa ukukhafula umlilo nentuthu.Zonke izinto ezisetshenziswayo kufanele zibe nezitifiketi ezivela eceleni ukuze zithobele izinga elifanele lalolu hlobo lwesisetshenziswa, i-UL1741, futhi uqiniseke ukuthi ukhetha ibhokisi lesihlanganisi selanga elihlangabezana nezidingo zobuchwepheshe zephrojekthi yakho.

Ithrendi entsha yengeza ubude bekhebula ngesixhumi se-PV ekugcineni.Kunokuba usonkontileka abhoboze izimbobo ebhokisini lesihlanganisi se-pv array futhi afake okokufakwayo esizeni, ikhebula lelanga lingafakwa efekthri, okuvumela isifaki ukuthi sivele sixhume amakhondatha okukhiphayo ebhokisini lesihlanganisi lamalungu afanayo sisebenzisa izixhumi ze-PV zokukhwelana.

Ngokuya ngohlelo lokusebenza, amabhokisi okuhlanganisa izintambo ze-PV afakwe izinto zokuqapha ezikala okwamanje, i-voltage nezinga lokushisa ukuze kuqinisekiswe ukutholakala kweyunithi yezinhlamvu kanye nokwandisa ukukhiqizwa kwamandla.Ama-subsystems akhiwe amabhokisi okuhlanganisa intambo yelanga angamiswa ngokuya ngenani lezintambo, i-voltage kanye nesilinganiso samanje.I-Slocable inikezela ngochungechunge oluhlukile lwamabhokisi okuhlanganisa amandla elanga, ngalinye elinikezelwe ezimweni ezithile zokufakwa ngokucushwa okujwayelekile.

Izinzuzo zamabhokisi e-Solar PV Combiner:

1. Ibhokisi lokuhlanganisa ilanga le-PV lithuthukisa ukuphepha kwephaneli yelanga kanye nayo yonke isikhungo samandla se-PV.
2. Amabhokisi okuhlanganisa ama-Photovoltaic, aziwa nangokuthi i-DC switchboard, ahlanganiswe efektri nemishini yokuqapha,Amafuse e-DC, amadivaysi okuvikela ukukhuphukafuthi unqamule amaswishi njengesixazululo se-plug-and-play.
3. Osayizi bezindlu abahlukene ukuze kube nembobo eguquguqukayo efinyelela kuzintambo ezingu-32.

Izici ze-Solar DC Combiner Box:

1. Isixazululo sebhokisi lesihlanganisi esihlanganiswe efekthri sazo zonke izikali zezindlu zokuhlala, ezentengiselwano nezisetshenziswayo, i-1000V kanye ne-1500VDC ngentambo eyodwa noma izintambo ezingafika kwezingama-32;ukuqapha ngokuzithandela.
2. Ibhokisi lesihlanganisi se-DC lamukela ibhokisi langaphandle le-Gemini thermoplastic, elinamandla amakhulu kakhulu okusebenza.
3. Ngenxa yezakhiwo zemishini zebhokisi lesihlanganisi, livikelekile othulini, olwandle noma kukholomu yamanzi aqinile, amakhemikhali nemisebe ye-UV enamandla: IP66, IK10 ne-GWT 750°C.
4. Izici zikagesi: Ukufakwa kabili (I-Class II), i-Ui/Ue: 1000V DC/1500V DC.
5. Kuye ngezimo zesayithi, izivalo ze-Gemini zingafakwa phansi noma zifakwe odongeni.
