Amabhokisi okuxhuma amaphaneli elangaasetshenziswa ochwepheshe bakagesi ukuvikela izintambo ekushaqekeni ngokomzimba nasekulunyweni yizinambuzane ngokusebenzisa amapayipi ekhebula ngaphandle kwezintambo.Futhi ekuxhumekeni kwekhebula (noma ekhoneni lepayipi lekhebula), sebenzisa ibhokisi lokuhlangana njengenguquko.Amashubhu amabili ekhebula axhunywe ebhokisini lokuhlangana, futhi izintambo ezingaphakathi kwamashubhu zixhunywe ngaphakathi kwebhokisi lokuhlangana.Ibhokisi lokuxhumana le-solar lidlala indima yokuvikela nokuxhuma izintambo.
Umsebenzi webhokisi le-Solar junction ukuxhuma ugesi okhiqizwa imojula ye-PV kuzintambo zangaphandle.Njengoba amaphaneli elanga ngokuvamile adinga ukusetshenziswa ezindaweni ezingaphandle ezinokhahlo futhi abe newaranti efinyelela eminyakeni engu-25, amaphaneli elanga nawo anezidingo eziphakeme zamabhokisi okuxhumana.Ngaphezu kokuqinisekisa ukuthembeka kokuxhumeka, ukuqinisekisa ukuphepha kwe-wiring yangaphakathi, ibhokisi lokuxhumana lephaneli yelanga liphinde libe nekhono eliphezulu lokulwa nokuguga, i-anti-UV;ukuba nezinga eliphezulu lokungangeni kwamanzi kanye nokuvikela uthuli, ngokuvamile ukuze kuzuzwe IP67 noma ngaphezulu;ingamelana namanje aphezulu (ngokuvamile idinga okungaphezu kuka-20A), i-voltage ephezulu (ngokuvamile i-volts engu-1000, imikhiqizo eminingi ingafinyelela ku-volts angu-1500);sebenzisa izinga lokushisa elibanzi (-40 ℃ ~ 85 ℃), izinga lokushisa eliphansi lokusebenza kanye nochungechunge lwezidingo.Futhi, ukuze unciphise futhi ugweme umphumela wendawo eshisayo, ama-diode ahlanganiswe ngaphakathi kwebhokisi le-solar junction.
Ukwakheka kwebhokisi lokuhlanganisa lephaneli ye-pv: ikhava yebhokisi (okuhlanganisa nendandatho yokuvala), umzimba webhokisi, amatheminali, ama-diode, izintambo, nezixhumi.
Izinto eziyisisekelo zomzimba webhokisi kanye nesembozo sebhokisi lokuxhuma iphaneli yelanga livame ukusetshenziswa i-PPO, enezinzuzo zokuqina okuhle, ukumelana nokushisa okuphezulu, ukungashi, amandla aphezulu kanye nezakhiwo ezinhle kakhulu zikagesi.Ngaphezu kwalokho, i-PPO iphinde ibe nezinzuzo zokumelana nokugqokwa, okungezona ubuthi, ukumelana nokungcola, ukumelana nesimo sezulu esihle, njll. I-PPO inezinye zezinto ezincane kakhulu ze-dielectric constants kanye nokulahlekelwa kwe-dielectric phakathi kwamapulasitiki obunjiniyela, futhi cishe ayithinteki ukushisa nomswakama, okuvumela izosetshenziswa ezindaweni zikagesi eziphansi, eziphakathi nendawo neziphezulu.I-PPO ehlanzekile engashintshiwe ine-viscosity ephezulu yokuncibilika, ukucutshungulwa okungekuhle nokubumbeka, futhi ayikwazi ukubunjwa umshini wokubumba umjovo.Ukuze kuxazululwe le nkinga, i-PPO ingashintshwa ngezindlela ezibonakalayo noma zamakhemikhali, futhi i-PPO eguquliwe ibizwa nge-MPPO.Uhlobo lwe-MPPO oluncibilikayo olushisayo lubunjwa umshini wokubumba umjovo ukwenza umzimba webhokisi.Indlela yokukhiqiza yesivalo iyafana nomzimba webhokisi, isikhunta kuphela esihlukile.Ukuze uthuthukise ukusebenza okungangeni manzi, isembozo sizoba nesigxivizo esenziwe nge-silicone.
Uhlangothi okokufaka lwetheminali luxhunywe kusinki ibha yephaneli yelanga, futhi uhlangothi lokuphumayo luxhunywe kukhebula.Impahla yetheminali ngokuvamile iyithusi elimsulwa noma ithusi elifakwe ngothayela, ithusi elifakwe ngothayela liyithusi elinothayela omncane wensimbi ngaphezulu.Ithini ngokuyinhloko idlala indima ekuvikeleni ithusi ukuze ivimbele ithusi ukuthi lifakwe i-oxid ukuze lenze ithusi eliluhlaza ukuze libe nomthelela ekusebenzeni.Ngesikhathi esifanayo, indawo encibilikayo ephansi kathayela, kulula ukuyishisela, nokuhamba kahle kukagesi, ungasebenzisa futhi ithusi elicwecwe nge-chromium ukwenza itheminali.
Ama-diode anezici zomqhubi oyedwa.Ama-diode angahlukaniswa njengama-diode alungisa kabusha, ama-diode asheshayo, ama-voltage regulator diode nama-light emitting diode.
Amakhebuli asetshenziswa kakhulu anethusi noma amakhondatha ethusi athayiwe ngaphakathi kanye nezingqimba ezimbili ezivikelayo ngaphandle, okuyi-polyvinyl chloride (PVC) insulation kanye nejakhethi ye-PVC, kodwa i-PVC ayihlangabezani nezimfuneko zokuguga futhi iqukethe i-halogen, ekhulula igesi ye-chlorine uma ishisiwe futhi ingaphephile kakhulu.Izintambo ze-Photovoltaic zidinga ama-polyolefin axhumene ne-radiated cross-linked ngaphezu kwama-conductor (ubuchwepheshe bokuxhumanisa i-radiation cross-linking bubhekisela ekuphenduleni kokuxhumanisa okuphambanayo kwama-macromolecules okuzuzwa ngokushisa imisebe, ukuze i-polymer eqondile ibe i-polymer enesakhiwo senethiwekhi yesikhala esingama-degree amathathu, ukuze izinga lokushisa layo elivumelekile lokusebenzisa isikhathi eside liyakhuphuka lisuka ku-70°C liye ngaphezu kuka-90°C, futhi izinga lokushisa elivumelekile lesifunda esifushane liyakhuphuka lisuka ku-140°C liye ngaphezu kuka-250°C, kuyilapho ligcina izakhiwo zalo zikagesi ezinhle kakhulu futhi lithuthukisa izinga lokushisa. ukusetshenziswa kwangempela kokusebenza. ) Ngaphakathi kwekhebula le-photovoltaic kunentambo yethusi enendawo ephambanayo engu-4mm2.Uma i-current yamanje yephaneli yelanga (ngaphansi kwama-amps angu-10) ibalwa, intambo yethusi engu-2.5mm2 yanele, kodwa uma kucatshangelwa ukuthi ama-solar panel ngokuvamile asebenza ngaphansi kwezimo eziphakeme zokushisa, lapho umthamo wekhebula uyancipha futhi uhlelo lwamanje luphakeme kakhulu. , indawo enkulu ye-cross-sectional yocingo lwethusi kufanele isetshenziselwe ukuqinisekisa ukuphepha kwesistimu.
Izixhumi zivimba noma zihlukanise phakathi kwamasekhethi, zivala ukugeleza kwamandla ukuze isekethe ifeze umsebenzi wayo ohlosiwe.Ipheya yezixhumi iqukethe isixhumi sowesilisa nesixhumi sowesifazane, sisebenzisa i-PPO njengento evikelayo.Isixhumi sowesilisa sisetshenziselwa itheminali ephozithivu yengxenye kanti isixhumi sowesifazane sisetshenziselwa itheminali enegethivu.
Amabhokisi amaningi okuxhumana elanga asebenzisa izinamatheliso ze-silicone potting ukuze avikele izingxenye zawo zangaphakathi futhi athuthukise ukusebenza okushisayo.I-Junction box potting adhesive isekelwe ikakhulukazi ku-silicone enezingxenye ezimbili.I-silicone enezingxenye ezimbili yakhiwe ngo-A, B izinhlobo ezimbili zeglue, Uhlobo lweglue lubizwa ngokuthi i-base glue, uhlobo lwe-B lweglue lubizwa ngokuthi i-curing agent.Lapho iglue yohlobo lwe-AB ixutshwa ngenani elithile ngaphambi kokusetshenziswa, ifakwa ebhokisini lokuhlangana ukuze ilashwe ngemva kokuxuba.Inqubo yokuxuba kufanele icophelele kakhulu ukuze kuncishiswe ukuxubana komoya.Ingcina ye-Silicone potting ingelapheka ekamelweni lokushisa (25 ℃) noma ngokufudumeza.Izinamatheliso zegumbi zokupholisa izimbiza zingasheshiswa ngokushisisa.I-ejenti yokwelapha kufanele ixutshwe ngaphambili ngaphambi kokusetshenziswa, njengoba imvula ethile ingase ivele ngesikhathi sokulethwa nokugcinwa.I-ejenti elaphayo ijwayele ukusabela ngomswakama emoyeni, ngakho-ke ukunakekelwa okwengeziwe kufanele kuthathwe ukugwema ukuthintana nomoya ngaphambi kokusetshenziswa.
1. Umsebenzi we-MPPT: lungiselela ubuchwepheshe bokulandelela amandla aphezulu kanye nedivayisi yokulawula iphaneli ngayinye ngokusebenzisa isofthiwe ne-hardware, lobu buchwepheshe bungakhulisa amathuba okuthuthukisa ukuncishiswa kokuphehlwa kwamandla kwesiteshi samandla okubangelwa izici zamaphaneli ahlukahlukene, futhi kunciphise. "umthelela womgqomo" ekusebenzeni kahle kwesikhungo samandla, ungakhuphula kakhulu umthamo wokuphehla ugesi wesiteshi sikagesi.Kusukela emiphumeleni yokuhlolwa, ukusebenza kahle okuphezulu kokukhiqiza amandla kohlelo kungakhushulwa ngisho nangama-47.5%, kukhuphule imbuyiselo yokutshalwa kwezimali futhi kunciphise kakhulu isikhathi sokubuyisela.
2. Umsebenzi wokuvala shaqa ngobuhlakani ngaphansi kwezimo ezingavamile njengomlilo: Uma kuba nomlilo, i-algorithm yesofthiwe eyakhelwe ngaphakathi yebhokisi loxhumano lwelanga izosebenzisana nesekhethi yezingxenyekazi zekhompuyutha ukuze kunqunywe phakathi kwama-millisecond angu-10 ukuthi ingabe kukhona okungavamile kwenzeke, futhi ithathe isinyathelo ukunqamula ukuxhumana phakathi kwephaneli ngayinye, i-voltage engu-1000V yehle iye cishe ku-40V kagesi eyamukelekayo yomuntu ukuze kuqinisekiswe ukuphepha kwabacimi bomlilo.
3. Ukusetshenziswa kobuchwepheshe bokulawula obuhlanganisiwe be-thyristor be-MOSFET, esikhundleni se-Schottky diode yendabuko.Lapho ukufiphala kwenzeka, ungaqala ngokushesha i-MOSFET bypass yamanje ukuze uvikele ukuphepha kwephaneli, kuyilapho i-MOSFET ngenxa yezimpawu zayo ezihlukile ze-VF eziphansi, ukuze isizukulwane sokushisa esiphelele ebhokisini lokuhlangana siyingxenye eyodwa kweshumi kuphela yebhokisi elivamile le-junction. , ubuchwepheshe bunweba kakhulu impilo yesevisi yebhokisi lokuhlangana, ukuvikela kangcono impilo yebhethri.
