Ulwakhiwo kunye neMisebenzi ePhambili yeBhokisi yoQhagamshelwano lwePaneli yeSolar

       Iibhokisi zoqhagamshelo zephaneli yelangazisetyenziswa ngamagcisa ombane ukukhusela iintambo kwingxubakaxaka ebonakalayo nasekulunyweni zizinambuzane ngokusebenzisa imibhobho yentambo ngaphandle kweentambo.Kwaye ekudibaneni kwekhebula (okanye kwikona yombhobho wentambo), sebenzisa ibhokisi ye-junction njengenguqu.Iityhubhu ezimbini zekhebula zixhunywe kwibhokisi ye-junction, kwaye iintambo ngaphakathi kweetyhubhu zixhunyiwe ngaphakathi kwebhokisi le-junction.Ibhokisi yokudibanisa yelanga idlala indima yokukhusela kunye nokudibanisa iintambo.

Umsebenzi webhokisi ye-Solar junction kukudibanisa umbane owenziwe yimodyuli ye-PV kwi-wiring yangaphandle.Ekubeni iipaneli zelanga zihlala zifuna ukusetyenziswa kwiindawo ezinqabileyo zangaphandle kwaye zinewaranti ukuya kwi-25 iminyaka, iipaneli zelanga nazo zineemfuno eziphezulu zeebhokisi zokuxhuma.Ukongezelela ekuqinisekiseni ukuthembeka koqhagamshelwano, ukuqinisekisa ukhuseleko lwe-wiring yangaphakathi, ibhokisi yokudibanisa ipaneli yelanga nayo ifuna ukuba ne-anti-aging ephezulu, i-anti-UV;ukuba nenqanaba eliphezulu lokungangeni kwamanzi kunye nothuli, ngokubanzi ukufikelela kwi-IP67 okanye ngaphezulu;inokumelana nokuphezulu kwangoku (ngokubanzi kufuna ngaphezulu kwe-20A), i-voltage ephezulu (ngokubanzi i-1000 volts, iimveliso ezininzi zinokufikelela kwi-1500 volts);sebenzisa uluhlu olubanzi lobushushu (-40 ℃ ~ 85 ℃), ubushushu obuphantsi bokusebenza kunye nothotho lweemfuno.Kwakhona, ukuthothisa kunye nokuphepha isiphumo sendawo eshushu, ii-diode zihlanganiswe ngaphakathi kwebhokisi le-junction yelanga.

Ukuqulunqwa kwebhokisi ye-pv panel junction: isigqubuthelo sebhokisi (kubandakanya umsesane wokutywina), umzimba webhokisi, iitheminali, iidiode, iintambo, kunye nezihlanganisi.

Ubume beBhokisi yoQhagamshelwano lwePaneli yeSolar

1. Umzimba webhokisi kunye neqweqwe lebhokisi lesiphambuka

Isiseko sezinto ezisisiseko somzimba webhokisi kunye nesimbozo sebhokisi yokudibanisa iphaneli yelanga isetyenziswa ngokuqhelekileyo i-PPO, enenzuzo yokuqina okulungileyo, ukumelana nobushushu obuphezulu, ukungatsha, amandla aphezulu kunye neempawu ezintle zombane.Ukongeza, i-PPO ikwanazo iingenelo zokunganyangeki, i-non-toxic, ukumelana nongcoliseko, ukumelana nemozulu elungileyo, njl. njl. iza kusetyenziswa kwiindawo zombane eziphantsi, eziphakathi kunye neziphezulu.I-PPO ecocekileyo engalungiswanga ine-viscosity ephezulu yokunyibilika, ukungaqhubeki kakuhle kunye nokubumba, kwaye ayikwazi ukubunjwa ngumatshini wokubumba inaliti.Ukuze kulungiswe le ngxaki, i-PPO inokuguqulwa ngeendlela zomzimba okanye zekhemikhali, kwaye i-PPO elungisiweyo ibizwa ngokuba yiMPPO.Uhlobo olushushu olunyibilikayo lweMPPO lubunjwa ngumatshini wokubumba wenaliti ukwenza umzimba webhokisi.Indlela yokuvelisa i-lid iyafana nomzimba webhokisi, i-mold kuphela eyahlukileyo.Ukuphucula ukusebenza kwamanzi, isiciko siya kuba nesitywina esenziwe nge-silicone.

2. Itheminali

Icala legalelo le-terminal liqhagamshelwe kwi-sink bar yepaneli yelanga, kwaye icala lokuphuma lixhunyiwe kwintambo.Isixhobo setheminali lubhedu olusulungekileyo okanye ikopolo enkonkxiweyo, ubhedu olufakwe inkonkxa lubhedu olunobhedu olucekethekileyo lwenkcenkce phezu komhlaba.I-Tin idlala indima enkulu ekukhuseleni ubhedu ukukhusela ubhedu ekubeni lufakwe kwi-oxidized ukwenza ubhedu oluluhlaza ukuchaphazela ukuqhuba.Kwangaxeshanye, indawo enyibilikayo ephantsi ye-tin, kulula ukuyidibanisa, kunye nokuhanjiswa kakuhle kombane, unokusebenzisa ubhedu olucwecwe lwechromium ukwenza i-terminal.

3. Idayidi

IiDiodes zineempawu zomqhubi omnye.IiDiodes zinokuthi zihlelwe njenge-diode zokulungisa, ii-diodes ezikhawulezayo, ii-voltage regulator diode kunye ne-light etting diode.

4. Intambo yePV

Iintambo ezixhaphakileyo zinobhedu okanye izibhengezo zekopolo ezinkonkxiweyo ngaphakathi kunye nemigangatho emibini ekhuselayo ngaphandle, oko kukuthi i-polyvinyl chloride (PVC) yokugquma kunye nebhatyi yePVC, kodwa iPVC ayihlangabezani neemfuno zokwaluphala kwaye iqulethe ihalogen, ekhupha igesi yechlorine xa ishushu kwaye ayikhuselekanga kakhulu.Iintambo ze-Photovoltaic zidinga i-irradiated cross-linked polyolefins ukongeza kwii-conductor (i-radiation cross-linking technology ibhekisela kwi-reaction cross-linking ye-macromolecules ephunyeziweyo ngokusebenzisa i-irradiation, ukuze i-polymer ehambelanayo ibe yipolymer kunye nesakhiwo sothungelwano lwesithuba esithathu, ukuze ubushushu bayo bexesha elide obuvumelekileyo bonyuswa ukusuka kwi-70°C ukuya ngaphezulu kwe-90°C, kwaye iqondo lobushushu elivumelekileyo lesekethe emfutshane linyuswe ukusuka kwi-140°C ukuya ngaphezulu kwe-250°C, ngelixa ligcina iimpawu zalo zombane ezigqwesileyo nokuphucula umbane. ukusetyenziswa kwangempela kokusebenza. ) Ngaphakathi kwentambo ye-photovoltaic intambo yobhedu kunye nommandla we-cross-sectional we-4mm2.Ukuba umbane oqhelekileyo wepaneli yelanga (ngaphantsi kwee-amps ezili-10) ubalwa, i-2.5mm2 ucingo lobhedu lwanele, kodwa ngokuqwalasela ukuba iipaneli zelanga zihlala zisebenza phantsi kweemeko eziphezulu zokushisa, xa umthamo wentambo uyancipha kwaye inkqubo yangoku iphezulu kakhulu. , indawo enkulu ye-cross-sectional yocingo lobhedu kufuneka isetyenziswe ukuqinisekisa ukhuseleko lwenkqubo.

5. Isidibanisi

Iziqhagamshelo zibhloka okanye zihlukanise phakathi kweesekethe, zivale ukuhamba kwangoku ukuze isekethe ifezekise umsebenzi wayo.Izibini ezidityanisiweyo zibandakanya isinxibelelanisi esiyindoda kunye nesinxibelelanisi sowesifazane, sisebenzisa i-PPO njengesixhobo sokugquma.Isidibanisi sendoda sisetyenziselwa i-terminal ye-positive yecandelo kwaye ikhonkco yabasetyhini isetyenziselwa i-terminal engalunganga.

6. Ukugalela iGlue

Iibhokisi ezininzi ze-solar zisebenzisa i-silicone potting adhesives ukukhusela amacandelo abo angaphakathi kunye nokuphucula ukusebenza kwe-thermal.Ibhokisi yeJunction ye-adhesive potting potting isekelwe ikakhulu kwi-silicone yamacandelo amabini.I-silicone enamacandelo amabini yenziwe nge-A, B iindidi ezimbini zeglue, Uhlobo lweglue lubizwa ngokuba yi-base glue, uhlobo lweglu B lubizwa ngokuba yi-agent ephilisayo.Xa iglue yohlobo lwe-AB ixutywe kumlinganiselo othile ngaphambi kokusetyenziswa, ifakwa kwibhokisi yokuhlangana yokunyanga emva kokuxuba.Inkqubo yokuxuba kufuneka ilumke ngakumbi ukunciphisa ukuxubana komoya.Isincamathelisi se-silicone kwimbiza sinokunyangeka kwiqondo lobushushu begumbi (25℃) okanye ngokufudumeza.Iqondo lobushushu begumbi lokunyanga izinto zokuncamathelisa ezimbizeni zinokukhawuleziswa ngokufudumeza.I-ejenti yokunyanga kufuneka ixutywe ngaphambi kokusetyenziswa, njengoko imvula ethile ingenzeka ngexesha lokuhambisa kunye nokugcinwa.I-ejenti yokunyanga ivame ukusabela ngokufuma emoyeni, ngoko ke kufuneka kuthathelwe ingqalelo ngakumbi ukuphepha ukudibana nomoya ngaphambi kokusetyenziswa.

Umsebenzi weBhokisi yoQhagamshelwano lweSolar

1. Umsebenzi weMPPT: cwangcisa iteknoloji yokulandelela amandla aphezulu kunye nesixhobo sokulawula kwiphaneli nganye ngesofthiwe kunye ne-hardware, le teknoloji inokwandisa amathuba okuphucula ukuveliswa kombane wokunciphisa umbane wesikhululo samandla esibangelwa iimpawu zepaneli ezahlukeneyo, kunye nokunciphisa. "impembelelo yombhobho" ekusebenzeni kakuhle kweplanti yamandla, inokunyusa kakhulu umthamo wokuvelisa amandla kwisikhululo samandla.Kwiziphumo zovavanyo, ubuninzi bokuvelisa amandla enkqubo kunganyuswa ngama-47.5%, okonyusa imbuyekezo kutyalo-mali kwaye kuncitshiswe kakhulu ixesha lentlawulo.

2. Umsebenzi wokuvalwa okukrelekrele phantsi kweemeko ezingaqhelekanga ezinjengomlilo: Kwimeko yomlilo, i-algorithm yesoftware eyakhelweyo yebhokisi yonxibelelwano yebhokisi yelanga iya kusebenzisana nesekethe yehardware ukumisela ngaphakathi kwe-10 millisecond ukuba kukho into engaqhelekanga yenzekileyo, kwaye ithathe inyathelo lokuqala lucime unxibelelwano phakathi kwendawo nganye yombane, i-voltage ye-1000V ukuya kutsho malunga ne-40V yombane eyamkelekileyo yomntu ukuqinisekisa ukhuseleko lwabacimi-mlilo.

3. Ukusetyenziswa kwe-MOSFET thyristor iteknoloji yokulawula edibeneyo, endaweni ye-diode ye-Schottky yendabuko.Xa umthunzi usenzeka, ungaqala kwangoko i-MOSFET bypass yangoku ukukhusela ukhuseleko lwephaneli, ngelixa i-MOSFET ngenxa yeempawu zayo ezizodwa ezisezantsi ze-VF, ukuze isizukulwana sobushushu sisonke kwibhokisi yokuhlangana sisinye seshumi kuphela sebhokisi yokuhlangana eqhelekileyo. , iteknoloji yandisa kakhulu ubomi benkonzo yebhokisi ye-junction, ukukhusela ngcono ubomi bebhetri.
