Ibhokisi ye-photovoltaic junction yikhonkco phakathi kwepaneli yelanga (i-module array) kunye nesixhobo sokulawula ukutshaja kwelanga.Umsebenzi oyintloko kukudibanisa amandla aveliswa yiseli yelanga kunye nomgca wangaphandle, owahlulwe kwibhokisi ye-crystal silicon junction, ibhokisi ye-amorphous silicon junction, ibhokisi yokudibanisa udonga lwekhethini, eyenziwe ngamacandelo amathathu: ibhokisi yebhokisi, intambo kunye nesixhumi. .
Umsebenzi webhokisi ye-photovoltaic junction
Ibhokisi ye-module ye-Photovoltaic ye-junction iqulethwe ngokukodwa ngamacandelo amabini ebhokisi lebhokisi kunye nekhonkco, umsebenzi oyintloko kukudibanisa nokukhusela imodyuli ye-solar photovoltaic, ngelixa uqhuba okwangoku oveliswa yimodyuli ye-photovoltaic kubasebenzisi ukuba basebenzise.Ibhokisi le-junction liya kwenza indawo evaliweyo kunye nenkqubo yocingo, enika ukhuseleko kwimiphumo yokusingqongileyo kwiingcingo kunye nokudibanisa kwazo, ibonelela ngokukhuseleka kokufikeleleka kwiindawo eziphilayo, kunye nokunciphisa ukuxhatshazwa kwenkqubo yocingo edibeneyo kuyo.Umsebenzi owongezelelweyo kukukhusela icandelo locingo olukhokelela ekuthinteleni umphumo wendawo yokushisa.
Ukuqinisekiswa kweebhokisi ze-photovoltaic junction
Ukuze unikeze abasebenzisi izisombululo zoqhagamshelwano ezikhuselekileyo, ezikhawulezayo nezithembekileyo, iimveliso kufuneka zidlule kwi-TUV, isatifikethi se-IEC kunye nesiqinisekiso sesizwe.Okwangoku, ukuhlolwa komgangatho weemveliso zebhokisi ze-photovoltaic junction zivela kwi-TUV, isatifikethi se-UL.Abavelisi beebhokisi ezinkulu ze-junction e-China bazibophelele ekuphuhliseni iibhokisi ze-junction ezibonelela abasebenzisi ngezisombululo zoqhagamshelwano ezikhuselekileyo, ezikhawulezayo nezithembekileyo, kwaye basebenza nzima ukuba iimveliso zabo ziphumelele isiqinisekiso se-TUV, i-UL, njl.
Iimpawu zebhokisi ye-photovoltaic junction
1, iqokobhe lenziwe ngezinto ezikumgangatho ophezulu eziphuma kumazwe angaphandle, ezichasene nokuguga okuphezulu, ukuxhathisa kwe-UV;
I-2, ilungele ukusetyenziswa kwexesha lemveliso yangaphandle phantsi kweemeko ezinzima zokusingqongileyo, ukusetyenziswa okwenyani ukuya kwiminyaka engama-30;
3, ngokweemfuno zayo nayiphi na eyakhelwe-ngaphakathi 2 ~ 6 terminal;
4. Zonke iindlela zoqhagamshelo ziqhagamshelwe ngemowudi yokudibanisa ekhawulezayo.
Indima yebhokisi ye-photovoltaic junction
Ibhokisi yokudibanisa isetyenziselwa ukudibanisa uluhlu lwebhetri kwisixhobo sokulawula intlawulo.Ngoko ke, ngokuqhelekileyo kuyimfuneko ukuvezwa ngaphandle kunye nokuchatshazelwa ziinguqu ezahlukeneyo zokusingqongileyo.Ukongeza, iikhomponenti zebhokisi yesiphambuka ziya kuvelisa ubushushu, ngoko ke ibhokisi yokuhlangana ngaphakathi nangaphandle iya kuvelisa umahluko omkhulu woxinzelelo.Imiphumo yemozulu inokunyusa utshintsho kwiiyantlukwano zengcinezelo yangaphakathi nangaphandle.Ngoko ke, kuyimfuneko ukunxibelelana nomoya ukulungelelanisa ukungafani koxinzelelo lwangaphakathi nangaphandle ukukhusela ukusebenza kwamacandelo angaphakathi e-elektroniki kunye nokusebenza kokutywinwa kwebhokisi le-junction ukuba lichaphazeleke.Kwangaxeshanye, kuyimfuneko ukuvala izinto ezingcolisa ulwelo ezifana namanzi kunye nothuli olusuka kwindawo yangaphandle.
1, ukuphucula ukusebenza kokhuseleko lwamacandelo
2, indibano yokutywina yangoku inxalenye yemveliso (inxalenye yokukhokela)
3, yenza icandelo lisebenzise ngokulula ngakumbi kwaye lithembekile
Ukukhetha ibhokisi ye-Photovoltaic junction
Ukukhethwa kwebhokisi ye-photovoltaic junction ikakhulu kuxhomekeke kubukhulu bexesha langoku lecandelo, enye yeyona nto iphezulu yangoku yomsebenzi, enye i-short circuit current, ngokuqinisekileyo, ubuninzi bangoku obunokuthi icandelo likwazi ukuphuma xa i-short circuit current. , isantya esilinganisiweyo sebhokisi ye-junction kufuneka sibalwe ngokuhambelana nesiphaluka esifutshane sangoku, into yokhuseleko kufuneka ibe nkulu, kwaye ibhokisi ye-junction yinto encinci yokukhusela ngokuhambelana nobuninzi bokusebenza ngoku.
Shwankathela
Ibhokisi le-junction lisebenza njengekhonkco kwaye lisebenza njengebhuloho phakathi kwemodyuli yelanga kunye nesixhobo sokulawula njenge-inverter.Ngaphakathi kwebhokisi le-junction, i-current eveliswa yimodyuli yelanga ikhutshwe kwaye ingeniswe kwisixhobo sombane ngokusebenzisa i-wiring terminals kunye nezixhumi.Ukuze kuncitshiswe ukulahlekelwa kwamandla kwibhokisi ye-junction ukuya kwicandelo, izinto zokuqhuba ezisetyenziswa kwibhokisi ye-junction zifuna ukuchasana okuncinci, kwaye ukuchasana koqhagamshelwano lomgca webhasi yebhasi encinci.
