Ibhokisi le-photovoltaic junction liyisixhumi phakathi kwephaneli yelanga (uhlu lwamamojula) kanye nedivayisi yokulawula ukushaja kwelanga.Umsebenzi oyinhloko ukuxhuma amandla akhiqizwe i-solar cell nomugqa wangaphandle, ohlukaniswe nge-crystal silicon junction box, i-amorphous silicon junction box, ibhokisi lokuhlanganisa udonga lwamakhethini, elakhiwe izingxenye ezintathu: umzimba webhokisi, ikhebula nesixhumi. .
Umsebenzi webhokisi lokuhlangana le-photovoltaic
Ibhokisi le-junction lemojula ye-Photovoltaic ikakhulukazi lakhiwe izingxenye ezimbili zebhokisi lokuhlangana nesixhumi, umsebenzi oyinhloko ukuxhuma nokuvikela imodyuli ye-solar photovoltaic, ngenkathi uqhuba okwamanje owenziwe yi-module photovoltaic ukuze abasebenzisi basebenzise.Ibhokisi lokuxhuma lizokwakha isikhala esivalekile nesistimu yezintambo, ehlinzeka ngokuvikeleka emiphumeleni yemvelo yezintambo kanye noxhumo lwazo, inikeze ukuvikeleka kokufinyeleleka kwezingxenye ezibukhoma, futhi inciphise ukungezwani kwesistimu yezintambo ezixhunywe kuyo.Umsebenzi ongeziwe uwukuvikela ingxenye yentambo yokuhola ukuvimbela umphumela wendawo yokushisa.
Ukuqinisekiswa kwamabhokisi okuhlangana kwe-photovoltaic
Ukuze unikeze abasebenzisi izixazululo zokuxhuma eziphephile, ezisheshayo nezithembekile, imikhiqizo kufanele idlule i-TUV, isitifiketi se-IEC nesitifiketi sikazwelonke.Njengamanje, ukuhlolwa kwekhwalithi yemikhiqizo yebhokisi le-photovoltaic junction kuvela ku-TUV, isitifiketi se-UL.Abakhiqizi abakhulu bamabhokisi e-junction e-China nabo bazibophezele ekuthuthukiseni amabhokisi okuhlangana ahlinzeka abasebenzisi ngezixazululo zokuxhuma eziphephile, ezisheshayo nezithembekile, futhi basebenza kanzima ukuze imikhiqizo yabo iphumelele isitifiketi se-TUV, UL, njll.
Izici zebhokisi lokuhlangana le-photovoltaic
I-1, igobolondo lenziwe ngezinto zokusetshenziswa ezithuthukisiwe ezivela kwamanye amazwe, ezine-anti-aging ephezulu kakhulu, ukumelana ne-UV;
2, ilungele ukusetshenziswa isikhathi sokukhiqiza ngaphandle ngaphansi kwezimo ezinzima zemvelo, ukusetshenziswa kwangempela okufika eminyakeni engama-30;
3, ngokwezidingo zanoma iyiphi i-terminal eyakhelwe ngaphakathi engu-2 ~ 6;
4. Zonke izindlela zokuxhuma zixhunywe ngemodi ye-plug-in yokuxhuma ngokushesha.
Indima yebhokisi lokuhlangana le-photovoltaic
Ibhokisi lokuhlangana lisetshenziselwa ukuxhuma uhlu lwebhethri kudivayisi yokulawula ukushajwa.Ngakho-ke, ngokuvamile kuyadingeka ukuvezwa ngaphandle futhi uthinteke izinguquko ezihlukahlukene zemvelo.Ngaphezu kwalokho, izingxenye ze-electronic zebhokisi lokuhlangana zizokhiqiza ukushisa, ngakho ibhokisi lokuhlangana ngaphakathi nangaphandle lizokhiqiza umehluko omkhulu wengcindezi.Imiphumela yesimo sezulu ingandisa izinguquko ekuhlukeni kwengcindezi yangaphakathi nangaphandle.Ngakho-ke, kuyadingeka ukuxhumana nomkhathi ukulinganisa umehluko wengcindezi yangaphakathi nangaphandle ukuze kuvinjelwe ukusebenza kwezingxenye ze-elekthronikhi zangaphakathi kanye nokusebenza kokuvala kwebhokisi lokuhlangana ukuthi kungathinteki.Ngesikhathi esifanayo, kuyadingeka ukuvimba ukungcola okuqinile noketshezi njengamanzi nothuli oluvela endaweni yangaphandle.
1, ukuthuthukisa ukusebenza kokuphepha kwezingxenye
2, umhlangano wokuvala ingxenye yokuphumayo yamanje (ingxenye yomthofu)
3, sebenzisa ingxenye elula futhi enokwethenjelwa
Ukukhethwa kwebhokisi le-Photovoltaic junction
Ukukhethwa kwebhokisi lokuhlangana kwe-photovoltaic ngokuyinhloko kuncike kusayizi wamanje wengxenye, enye iyinani eliphezulu lamanje lomsebenzi, enye i-current circuit circuit, yebo, inani eliphezulu lamanje ukuthi ingxenye ingakhipha lapho i-current circuit short. , umthamo wamanje olinganiselwe webhokisi lokuhlangana kufanele ubalwe ngokuvumelana nomjikelezo omfushane wamanje, isici sokuphepha kufanele sibe sikhulu ngokuqhathaniswa, futhi ibhokisi lokuhlangana liyisici sokuphepha esincane ngokuya ngenani eliphezulu lokusebenza lamanje.
Fingqa
Ibhokisi lokuhlangana lisebenza njengesixhumi futhi lisebenza njengebhuloho phakathi kwemoduli yelanga kanye nedivayisi yokulawula efana ne-inverter.Ngaphakathi kwebhokisi le-junction, i-current ekhiqizwa i-module ye-solar ikhishwa futhi ingeniswe emishini kagesi ngokusebenzisa amatheminali ezintambo kanye nezixhumi.Ukuze kuncishiswe ukulahlekelwa kwamandla kwebhokisi lokuhlangana kuya engxenyeni, into eqhutshwayo esetshenziswe ebhokisini lokuhlangana idinga ukumelana okuncane, futhi ukumelana nokuxhumana komugqa wokuhola webhasi kuncane.
