Uyini umsebenzi oyinhloko we-Photovoltaic Welding Strip Rolling Mill

      I-Photovoltaic Welding Strip Rolling Mill iyisisetshenziswa esiyinhloko sokucubungula ngokunemba kwamaribhoni e-photovoltaic. Isetshenziswa kakhulukazi ukugingqa izintambo eziyindilinga zethusi/zethusi ezingaphekiwe zibe amaribhoni ayisicaba (owaziwa nangokuthi amabhasi noma izixhumi ezixhumanisayo) ezinogqinsi oluthile nobubanzi ngezinqubo eziningi zokugoqa ezibandayo. Kuyimishini eyinhloko ochungechungeni lokukhiqiza imojula ye-photovoltaic, iqinisekisa ukusebenza kahle kokudluliselwa kwamanje kanye nokuthembeka kwemojula. Imisebenzi yayo ibonakala ngokuyinhloko kulezi zici ezine ezilandelayo:

1.Finyelela ukwakheka okunembile kwamaribhoni e-solder ukuze uhlangabezane nezidingo zokuxhuma amaseli e-photovoltaic

       Imigqa yegridi yamaseli e-Photovoltaic mincane kakhulu, idinga amaribhoni ayisicaba ukuze kuzuzwe ukuthintana kwendawo nokunciphisa ukumelana nokuxhumana. Ngokulawula okunembile kwengcindezi eginqikayo, isivinini se-roller, kanye nokusabalalisa kokudlula, umshini wokugaya ungagingqa izintambo eziyindilinga zethusi zibe amaribhoni ayisicaba anogqinsi luka-0.08~0.3mm nobubanzi obungu-0.8~5mm, ngokubekezelelana okulawulwa ngaphakathi kuka-±0.005mm. Lokhu kuhlangabezana nezimfuneko zokuvumelana nezimo zokushisela zokucaciswa okuhlukile kwamaseli (i-PERC, i-TOPCon, i-HJT, njll.), kuyilapho kuqinisekisa ukuthi ingaphezulu lamaribhoni libushelelezi futhi alinabhar, kugwema ukunwaya imigqa yegridi yeseli.

2.Thuthukisa i-conductivity kanye nezakhiwo zemishini ye-welding strip

       Ngesikhathi senqubo yokugoqa ebandayo, izinhlamvu zangaphakathi zomucu wethusi ziyacwengwa futhi zifakwe i-fiber, okungagcini ngokugqamisa amandla okuqina we-solder strip (kufika ku-300MPa), ukuvimbela ukuphuka kwe-solder strip ngesikhathi sokupakishwa kwengxenye noma ukusetshenziswa kwangaphandle; kodwa futhi kuthuthukisa ukuqhutshwa kwethusi (i-conductivity yezintambo zethusi ngobumsulwa ≥99.9% ingafinyelela ngaphezu kwe-100% IACS ngemva kokugoqa), ukunciphisa ukulahlekelwa kwamanje ngesikhathi sokudlulisa nokuthuthukisa ngokuqondile ukusebenza kahle kokukhiqizwa kwamandla kwezingxenye ze-photovoltaic.

3.Beka isisekelo senqubo elandelayo yokucwecwa ngothayela

        Ingaphezulu le-solder strip eyisicaba elakhiwe ngokugingqika inokuqina okufanayo, okuthuthukisa amandla okubopha nongqimba lwe-tin plating futhi ivimbele izindaba ezinjengokulimala kokusoda nokuhlukaniswa okubangelwa ukuxebuka kongqimba lwe-tin plating. Ezinye izigayo ezigoqayo ezisezingeni eliphezulu ziphinde zihlanganise imisebenzi yokuhlanza ku-inthanethi, ukomisa, kanye nokuqondisa ukuze kususwe amabala kawoyela nezingqimba ze-oxide ebusweni bomugqa we-solder, kuthuthukiswe nakakhulu ikhwalithi ye-tin plating kanye nokuqinisekisa ukumelana nokugqwala kanye nokuthembeka kwe-solder ye-solder strip.

I-4.Izivumelanise nezidingo zokukhiqiza okukhulu nokuguquguqukayo

        Izigayo zeribhoni zesimanje ze-photovoltaic (PV) zifaka amandla okugingqika aqhubekayo ngesivinini esiphezulu kanye namakhono okushintsha ukucaciswa okusheshayo, anezivinini eziginqikayo ezifinyelela ku-60~120m/min, ezihlangabezana nezidingo zokukhiqizwa kwenqwaba yamamojula e-PV. Ngesikhathi esifanayo, ngokushintsha ama-roller kanye nemingcele yenqubo yokulungisa, ukukhiqizwa kokucaciswa okuhlukile kwamaribhoni kungashintshwa ngokushesha, ukujwayela izidingo zokucubungula imikhiqizo emisha efana ne-HJT module amaribhoni okushisa aphansi kanye namaribhoni anezinhlangothi ezimbili zemodyuli, okusiza amabhizinisi e-photovoltaic ukunciphisa izindleko nokwandisa ukusebenza kahle.
