Ibhokisi yokuhlangana yemodyuli ye-pv enokushenxiswa(izinto zePPO)

Ukukhethwa kweSolar PV Junction Box

Ulwazi oluphambili oluza kuqwalaselwa ekukhethweni kwebhokisi ye-PV junction kufuneka ibe yimodyuli yangoku.Omnye ngowona msebenzi uphezulu wangoku kwaye omnye ngumbane omfutshane.Ngokuqinisekileyo, i-short-circuit current ngowona mzuzu uphezulu onokukhutshwa yimodyuli.Ngokutsho kwe-short-circuit current, i-current rated current yebhokisi ye-junction kufuneka ibe nokhuseleko olukhulu.Ukuba ibhokisi ye-junction ye-PV yelanga ibalwa ngokuhambelana nobuninzi bokusebenza ngoku, ukhuseleko luncinci.
Esona siseko sobunzululwazi sokhetho kufuneka sisekelwe kumthetho wotshintsho lwangoku kunye nombane webhetri omele ukhutshwe ngamandla okukhanya.Kuya kufuneka uqonde indawo apho imodyuli oyivelisayo isetyenzisiweyo, kwaye ukukhanya kungakanani kule ndawo, kwaye emva koko uthelekise ibhetri Ijika lenguqu yangoku yechip kunye nokukhanya kokukhanya, phanda ubuninzi obunokwenzeka ngoku, kwaye emva koko ukhethe umjelo okalisiweyo webhokisi yesiphambuka.

1. Ngokwamandla emodyuli ye-photovoltaic, i-150w, i-180w, i-230w, okanye i-310w?
2. Ezinye iinkcukacha zamacandelo.
3. Iiparamitha zediode, 10amp, 12amp, 15amp okanye 25amp?
4. Eyona ngongoma ibalulekileyo, inkulu kangakanani i-short-circuit current?Kolu vavanyo, ukhetho lwe-diode luxhomekeke kwezi zixa zilandelayo:
Okwangoku (inkulu ingcono), iqondo lokushisa eliphezulu le-junction (incinci ingcono), ukuxhathisa kwe-thermal (incinci ingcono), i-voltage drop (encinci ingcono), i-voltage ye-reverse breakdown (ngokubanzi i-40V ikude ngokwaneleyo).

Ibhokisi yeNdibaniselwano yokwahlula

Ukususela ngoJuni 2018, ibhokisi ye-junction ye-solar ngokuthe ngcembe ifumene isebe ukusuka kwibhokisi ye-junction yokuqala edibeneyo ngo-2015:ibhokisi yesiphambuka, kwaye yenze isiphumo sesikali kwi-Shanghai Photovoltaic Exhibition, emele ukuba kunokwenzeka iibhokisi ze-PV ze-junction kwixesha elizayo Faka umkhwa wokuhlukahluka kunye nophuhliso oluhambelanayo.
Iibhokisi ezidityanisiweyo zesiqwenga esinye zisetyenziswa ikakhulu kumacandelo esakhelo esiqhelekileyo, kwaye iibhokisi zokudityaniswa kohlobo olukwahlulahlula zisetyenziswa ikakhulu kumalungu amatsha aneglasi ephindwe kabini.Xa kuthelekiswa neyokuqala, le yokugqibela isenokufuneka ngakumbi kwiimarike nabathengi ngoku.Emva koko, kusondele ukuqonda ngokupheleleyo ukuba iindleko zokuvelisa amandla e-photovoltaic zingaphantsi kwentlawulo yombane, oku kuthetha ukuba iindleko zoshishino lwe-photovoltaic ziya kuncitshiswa ngakumbi, kwaye umda wenzuzo yebhokisi ye-photovoltaic junction iya kucinywa ngakumbi.Ibhokisi le-junction ye-split izalwa kunye ne-mission "yokunciphisa iindleko" kwaye ihlala iphuculwa.

Izinto ezilungileyo zeIbhokisi yeNdibaniselwano enezahlulo ezintathu

1. Ukunciphisa kakhulu inani lokuzaliswa kunye neembiza.Umzimba webhokisi enye i-3.7ml kuphela, eyanciphisa kakhulu iindleko zokuvelisa, kwaye inzuzo yalo bukhulu buncinci yenza indawo yokudibanisa kwimodyuli encinci, ukwandisa indawo yokukhanya yepaneli ye-photovoltaic, ukwenzela ukuba isikhululo samandla se-photovoltaic somsebenzisi sinokufumana. iinzuzo ezinkulu.

2. Lungiselela ukwakheka kwegobolondo, kwaye umphumo wokulwa nokuguga unyuke kakhulu.Olu didi olutsha lwebhokisi yesiphambuka ithatha iteknoloji yophando kunye nophuhliso lwamva nje, kunye negobolondo layo (ibhokisi ye-junction, isinxibelelanisi) inamandla aphezulu okuchasana nokuguga kunye nokungena kwamanzi, kwaye inokusetyenziswa ngokuqhelekileyo phantsi kweemeko ezibuhlungu zokusingqongileyo.

3. Umgama ophakathi kwebha yebhasi ephuculweyo yi-6mm kuphela, kwaye i-diode ithatha i-welding yokumelana, uxhulumaniso luba lukhuselekile kwaye luthembeke ngakumbi.

4. Isiphumo esingcono sokutshatyalaliswa kobushushu.Xa kuthelekiswa nebhokisi ye-junction, ibhokisi ye-junction yokwahlula ivelisa ubushushu obuncinci kwaye inefuthe elingcono lokutshatyalaliswa kobushushu.

5. Gcina ubude bekhebula, kwaye unciphise ngokwenene iindleko kwaye ukwandise ukusebenza kakuhle.Uyilo olunamacandelo amathathu lukwatshintsha ukufakwa kunye nendlela yokuphuma, ukuze iibhokisi zokuhlangana ezilungileyo nezingalunganga zifakwe kwicala lasekhohlo nasekunene lephaneli yefotovoltaic, enciphisa kakhulu umgama phakathi kwepaneli yebhetri kunye noqhagamshelo lwesekethe. iphaneli yebhetri ngexesha lofakelo lobunjineli.Le ndlela echanekileyo ayigcini nje ukunciphisa ukulahleka kwentambo, kodwa inciphisa ukulahlekelwa kwamandla okubangelwa ubude bomgca, kunye nokwandisa amandla emodyuli.

Ngokubanzi, ibhokisi entsha ye-junction ye-three-split ingachazwa njengomzekelo "wezinga eliphezulu kunye nexabiso eliphantsi", kwaye ligqithise umgangatho we-TUV wamva nje (IEC62790).Uphuhliso oluyimpumelelo lwebhokisi ye-junction ye-split ibonisa ukuba i-China inendawo evumayo ngakumbi kwindlela yokukhuphisana ye-photovoltaic grid parity.

Ibhokisi yesiphambuka esahlulahlulwe kathathu

I-Supplement: I-Evolution ye-Solar PV Junction Boxes

Iibhokisi ze-Solar PV junction zihlala zigcina umsebenzi ofanayo, kodwa ngoku njengoko amandla ombane kunye nombane weepaneli zelanga zanda, ibhokisi ye-junction yelanga kufuneka iphucule amandla okukhusela amandla.

"Indima eqhelekileyo yebhokisi ye-junction ihlala ifana, kodwa iimodyuli ze-PV ziba namandla ngakumbi," kusho uBrian Mills, uMphathi weMveliso yePV yaseNyakatho yaseMelika kwi-Stäubli Electrical Connectors.“Njengoko iimodyuli zePV zifumana imveliso ephezulu nangaphezulu, ezo diode zokudlula kufuneka zenze umsebenzi omninzi.Indlela abawafunxa ngayo amandla kukuphelisa ubushushu, ngoko obu bushushu buphuma kwiidiode kufuneka kujongwane nabo.”

Iiswitshi zokudlula ezipholileyo zithatha indawo yediode zemveli kwezinye iibhokisi zokudityaniswa kwePV ukunciphisa ubushushu obugqithisileyo obuveliswa ziziphumo eziphezulu zemodyuli yePV.Xa iphaneli yelanga enomthunzi ifuna ukutshabalalisa amandla ngokwethuku, iidiode eziqhelekileyo zithintela oko kungenzeki, kodwa zivelise ubushushu kwinkqubo.Ukutshintsha okupholileyo kwe-bypass kusebenza njengokutshintsha / ukuvala, ukuvula isiphaluka xa iphaneli yelanga izama ukufunxa amandla, ukuthintela ukwakhiwa kobushushu.

"I-Bypass diodes yitekhnoloji ye-1950s," utshilo uMills.“Zirhabaxa kwaye zithembekile, kodwa umba wobushushu ubusoloko uyinkathazo.”Iiswitshi zokudlula ezipholileyo ziyayicombulula le ngxaki yobushushu, kodwa zibiza kakhulu kunediode, kwaye wonke umntu ufuna iimodyuli zesolar PV zibe zitshiphu kangangoko.

Ukufumana eyona bhangi inkulu, abanini benkqubo ye-PV abaninzi bajikela kwiiphaneli zelanga ze-bifacial.Nangona umbane uveliswa ngaphambili nangasemva kwiphaneli yelanga, amandla asengafakwa kwibhokisi yesiphambuka.Abavelisi beebhokisi ze-PV kuye kwafuneka bavelise izinto ezintsha ngoyilo lwabo.

"Kwiphaneli yelanga ye-bifacial, kufuneka ubeke ibhokisi ye-PV ye-junction emphethweni apho unokuqinisekisa ukuba umva awukho umthunzi," kusho uRosenkranz."Ekugqibeleni, ibhokisi yesiphambuka ayinakuba luxande, kufuneka ibencinci."

I-TE Connectivity inikezela ngeebhokisi ezintathu ezincinci ze-SOLARLOK PV Edge junction yeemodyuli ze-PV ze-bifacial, enye nganye ngakwesobunxele, phakathi, kunye neekona eziphezulu zasekunene zemodyuli, eneneni esebenza injongo efanayo njengebhokisi elikhulu lexande.I-Stäubli iphuhlisa ibhokisi ye-PV yokuhlangana ukuze ibekwe ecaleni komda opheleleyo weemodyuli ze-bifacial.

Ukuthandwa ngokukhawuleza kweemodyuli ze-PV ze-bifacial kuthetha ukuba uyilo lwebhokisi ye-PV ye-junction kufuneka iphuculwe ngexesha elifutshane.Olunye uhlaziyo olukhawulezileyo kwiinkqubo zelanga lubandakanya ukuvalwa ngokukhawuleza kunye neempawu ezahlukeneyo zenqanaba lecandelo elifunwa yiKhowudi yoMbane yeSizwe, kunye neebhokisi ze-PV zokuhlangana kufuneka kwakhona zigcine.

Ibhokisi ye-Stäubli ye-PV-JB/MF ye-multifunction junction ye-Stäubli inokwenziwa ngokwezifiso kunye nefomathi evulekileyo, ngoko inokulungela naluphi na uhlaziyo lwexesha elizayo, kuquka i-optimizers epheleleyo okanye i-micro-inverters, ukuba izixhobo zabo ze-elektroniki ziba zincinci ngokwaneleyo.

UQhagamshelwano lwe-TE lusanda kwazisa ibhokisi ye-smart PV edibanisayo edibanisa iibhodi zesekethe eziprintiweyo (PCBs) kwizisombululo zephaneli yelanga ngokubeka iliso, ukulungelelanisa kunye nokukwazi ukuvala ngokukhawuleza.

Abavelisi bebhokisi ye-PV ye-junction nabo bacinga ukongeza itekhnoloji ye-inverter kwiimodeli zabo zexesha elizayo.Iibhokisi zesiphambuka ezingahoywanga zitsala ingqalelo engakumbi.
