Kukhuphiswano oluqatha lwe "grid parity" kwishishini le-photovoltaic, ukulungiswa kweendleko ze-kilowatt-yure nganye yombane kuhambelana nokukhuphisana okungundoqo kwamashishini. Njengesixhobo esibalulekileyo ekuveliseni iimodyuli zeeseli zelanga, ukuchaneka kweqonga elihambayo le-photovoltaic string string welding machine lichaphazela ngokuthe ngqo umgangatho we-welding kunye nokusebenza kakuhle kwemveliso. I-platform ye-granite motion platform ezinikele kumatshini we-photovoltaic welding welding, kunye nokuzinza kwayo kwe-dimensional ye-0.5μm / ngonyaka, inikezela ngenkxaso yobugcisa yokunciphisa iindleko ze-kilowatt-yure ukusuka kwimilinganiselo emininzi.
Ukuzinza okuphezulu kuqinisekisa ukuchaneka kwe-welding kunye nokunciphisa inkunkuma yezinto eziphathekayo
Ngexesha lenkqubo yokudibanisa intambo yeeseli ze-photovoltaic, ukuphambuka kwindawo ye-welding kunokukhokelela ekudibaneni okungahambi kakuhle kweeseli, ngaloo ndlela kuchaphazela ukusebenza kakuhle kokuveliswa kwamandla kwiimodyuli kunye nokuvelisa iimveliso ezineziphene. Iqonga lokushukuma lemveli lithanda ukuguqulwa kobukhulu ngenxa yezinto ezifana nokutshintsha kobushushu bendalo kunye nokungcangcazela koomatshini, okukhokelela ekuphambukeni kwindawo ye-welding. I-coefficient yokwandiswa kwe-thermal yeqonga lezemidlalo le-granite kuphela (4-8) × 10⁻⁶/℃. Idityaniswe nesakhiwo sayo sangaphakathi esixineneyo nesifanayo, ukuzinza kwe-dimensional ye-0.5μm / ngonyaka kunokufezekiswa.
Ukuthatha umgca wokuvelisa imodyuli ye-photovoltaic ye-1GW njengomzekelo, ukuba iqonga lokunyakaza eliqhelekileyo liyamkelwa, ukuphambuka kwendawo ye-welding ebangelwa yi-dimensional deformation idlula i-0.1mm, enokubangela ukuba izinga le-welding defect yeeseli zelanga likhuphuke ukuya kwi-3%. Xa usebenzisa iiplatifomu zezemidlalo zegranite, izinga le-welding defect linokulawulwa ngaphakathi kwe-0.5%. Kuko konke ukucutha kwe-1% kwireyithi yesiphene, ngaphezu kwesigidi esinye se-yuan yeeseli zebhetri zinokugcinwa unyaka nonyaka, kuthoba ngokuthe ngqo ixabiso lemveliso yamacandelo kunye nokubeka isiseko sokuhla kweendleko nge-kilowatt-yure nganye.
Ukunciphisa ukuphindaphinda kokugcinwa kwezixhobo kunye nokuphucula ukusebenza kakuhle kwemveliso
Iqonga elishukumayo elinozinzo olulambathayo oluya kubangela ukuguga okukhawulezileyo kwamacandelo othumelo kunye nokuncipha kokuchaneka kokuma ngenxa yoguquko ngexesha lokusetyenziswa kwexesha elide, kwaye ke ngoko kufuna ulungelelwaniso nokugcinwa kwezixhobo rhoqo. Iiplatifomu zezemidlalo zeGranite, kunye nokuzinza kwazo okubalaseleyo, kunokunciphisa ngokufanelekileyo ukuvela kweengxaki ezinjalo.
Ngenxa yokwahluka kwayo okuncinci kwe-0.5μm ngonyaka, idigri yokunxiba yamacandelo aphambili anje ngesixhobo sokuhambisa kunye nenzwa yokubeka umatshini wokuwelda intambo iyancipha kakhulu. Ngokwedatha yokulinganisa yokwenene yeshishini elithile lokuvelisa i-photovoltaic, emva kokwamkela iqonga lokushukuma kwegranite, umjikelo wokugcinwa komatshini we-welding wentambo uye wandiswa ukusuka kanye ngenyanga ukuya kanye ngekota, kwaye ixesha elilodwa lokulondoloza liye lancitshiswa ukusuka kwiiyure ze-8 ukuya kwiiyure ze-3. Ukunciphisa ubuninzi bokugcinwa kwezixhobo kuthetha ukusebenza kakuhle kwemveliso kunye neendleko eziphantsi zokusebenza kwezixhobo kunye nokugcinwa. Ngokusekwe kumgca wemveliso kunye nomthamo wonyaka we-500MW, unokunyusa ixesha lokuvelisa elisebenzayo malunga neeyure ezingama-200 ngonyaka, ukuvelisa iimodyuli ezininzi ze-photovoltaic ezixabisa ngaphezu kwe-5 yezigidi ze-yuan, kwaye zinciphise kakhulu iindleko ze-kilowatt-yure.
Yandisa ubomi benkonzo yezixhobo kwaye unciphise iindleko zotyalo-mali
Iindleko zotyalo-mali zezixhobo zokuvelisa i-photovoltaic ziphezulu, kwaye ubomi benkonzo yezixhobo buchaphazela ngokuthe ngqo imbuyekezo kutyalo-mali lwamashishini. Ngenxa yotshintsho lwemilinganiselo yexesha elide kunye noguquko lwesakhiwo, amaqonga entshukumo aqhelekileyo ahlala engaphumeleli ukuhlangabezana neemfuno ezichanekileyo zemveliso ngaphezulu kweminyaka emihlanu. Ngenxa yoko, amashishini kufuneka atshintshe izixhobo kwangaphambili, ukwandisa uxinzelelo lotyalo-mali olusisigxina.
Iiplatifomu zezemidlalo ze-Granite, kunye neempawu zazo ezizinzile zomzimba kunye neekhemikhali, ziyakwazi ukugcina ukuchaneka okuphezulu ngexesha lokusetyenziswa kwexesha elide kunye nokwandisa ngokufanelekileyo ubomi benkonzo yonke yomshini wokuthunga intambo. Idatha evela kumenzi wesixhobo esithile se-photovoltaic ibonisa ukuba umatshini we-welding wentambo oxhotyiswe ngeqonga le-granite motion motion usengakwazi ukugcina ukuchaneka kokubeka i-welding ngaphakathi kwe-± 0.1mm emva kokusetyenziswa ngokuqhubekayo iminyaka eyi-8, ukuhlangabezana neemfuno zokuvelisa zamacandelo aphezulu. Ngokwahlukileyo, izixhobo ezisebenzisa iiplatifti zentshukumo eziqhelekileyo kufuneka zitshintshwe izinto zazo ezingundoqo okanye umatshini wonke uphuculwe emva kweminyaka emihlanu. Ukwandiswa kobomi benkonzo yezixhobo kwenza ukuba iindleko zotyalo-mali ze-asethi ezisisigxina zamashishini zabelwe ixesha elide, ngakumbi ukunciphisa inxalenye yokuhla kwexabiso kwindleko yekhilowathi yeyure nganye.
Ukuququzelela ukuveliswa kwamacandelo asebenzayo kunye nokunyusa ingeniso yokuveliswa kwamandla
Ukuzinza kwe-dimensional ye-0.5μm / ngonyaka kunika isiqinisekiso somatshini we-welding we-photovoltaic string to achieve high-precision welding, eyenza amashishini avelise iimodyuli ze-photovoltaic kunye nokusebenza okuphezulu. Kwizicelo ezisebenzayo zesikhululo samandla, amacandelo asebenza ngokufanelekileyo angafumana umthamo ophezulu wokuvelisa amandla kunye nesantya esisezantsi sokuthomalalisa, ngokwenjenjalo konyuswa ingeniso yokuveliswa kwamandla kwisikhululo samandla.
Ngokomzekelo, iimodyuli eziphindwe kabini zeglasi ezine-welding ezichanekileyo ezinokunyusa amandla okuvelisa amandla nge-3% ukuya kwi-5% xa kuthelekiswa neemodyuli eziqhelekileyo. Thatha i-100MW photovoltaic power station njengomzekelo. Ngokusebenzisa amacandelo akumgangatho ophezulu, inokuvelisa i-3 ukuya kwi-5 yezigidi ze-kilowatt-iiyure zombane ngonyaka. Ukunyuka kwengeniso yokwenziwa kombane kuthetha ukuncitshiswa okunxulumene neendleko zekilowatt-yure nganye, ukomeleza ngakumbi uqoqosho nokhuphiswano lwezikhululo zamandla ephotovoltaic.
Iqonga legranite elishukumayo elinikezelwe kumatshini wokuwelda intambo ye-photovoltaic, kunye nokuzinza kwe-dimensional ye-0.5μm / ngonyaka njengenzuzo yayo ephambili, inciphisa ngokupheleleyo iindleko zokuvelisa iimodyuli ze-photovoltaic kunye neendleko nge-kilowatt-yure yezikhululo zamandla ngokusebenzisa iindlela ezininzi ezinjengokuqinisekisa ukuchaneka kwe-welding, ukunciphisa ukugcinwa kwezixhobo, ukunciphisa ukugcinwa kwezixhobo kunye nokwandisa izixhobo zobomi. Inika inkxaso yobugcisa obuqinileyo kwishishini le-photovoltaic ukuphumeza "igrid parity" kunye nophuhliso oluzinzileyo.
