Utoliko oluneenkcukacha: Ii-Multi-Contact MC4 Connectors

I-MC4 ayikho into engaqhelekanga kwiingcali ze-photovoltaic, iphantse yafana ne-photovoltaic connectors.Iuqhagamshelwano oluninzi lweMC4inokufumaneka kumacandelo abalulekileyo okuvelisa amandla e-photovoltaic njengeemodyuli, iibhokisi zokudibanisa kunye ne-inverters, kwaye zijongene nokudibanisa okuyimpumelelo kwesikhululo samandla.

Ekupheleni kuka-2015, i-China ye-cumulative efakwe kwi-photovoltaic umthamo yayiyi-43.18GW, ibekwe kwindawo yokuqala kwihlabathi.Kubalwa kwisiseko malunga neeseti ze-4,200 ze-photovoltaic connectors ezisetyenziswe kwi-1MW, ngoku kukho malunga ne-180 yezigidi zeeseti zokudibanisa ezifakwe e-China.Ngokwembono yomngcipheko, kuthetha ukuba kukho ubuncinane i-180 lezigidi zeendawo zomngcipheko ekufuneka zibekwe esweni ngabanini bezikhululo zamandla abohlukeneyo.

Nangona kunjalo, le ndawo incinci idla ngokungakhathalelwa ngexesha loyilo, ukwakhiwa, kunye nokusebenza kunye nokugcinwa kwesikhululo sombane.Isizathu sinxulumene kakhulu nokuqonda komntu wonke i-MC4.

Mhlawumbi lixesha lokuba wazi isiqhagamshelo se-MC4 soqhagamshelwano oluninzi kwakhona.

Imbali emfutshane yezihlanganisi zelanga

Kunxibelelwano oluninzi lwe-MC4, i-1996 kunye ne-2002 yiminyaka emibini ebaluleke kakhulu.Ezi ngongoma zimbini ngexesha nazo zihambelana neendawo eziphambili zokuphuhlisa imboni ye-photovoltaic.Nangona i-MC4 ye-multi-contact ayizange ihambisane nemboni ye-photovoltaic, ukubonakala kwayo kuye kwakhuthaza kakhulu ukunyuka ngokukhawuleza kofakelo lwe-photovoltaic.

Ngaphambi kowe-1996, iintambo ze-photovoltaic zaziqhagamshelwe ngeetheminali ze-screw okanye uqhagamshelo lwe-splice.Ngokunyuka kwenani leenkqubo ze-photovoltaic ezifakwe, imboni inemfuno eyongezelelekileyo yezisombululo ezikhawulezayo, ezikhuselekileyo kunye nokulula ukusebenza.

        Ngenxa yokuba inkqubo ye-photovoltaic ibonakaliswe emoyeni, imvula, ilanga elitshisayo kunye nokutshintsha kweqondo lokushisa eligqithiseleyo ixesha elide, i-solar connector kufuneka ikwazi ukuziqhelanisa nale mimandla enzima.Akufunekanga kuphela ukuba bangabi namanzi, ubushushu obuphezulu obuphezulu kunye nokumelana nemozulu kwimitha ye-ultraviolet, kodwa kunye nokukhuselwa komnxeba, amandla aphezulu okuthwala ngoku kunye nokusebenza okuphezulu.Ngexesha elifanayo, ukuchasana koqhagamshelwano oluphantsi nako kuqwalaselwa okubalulekileyo.Konke oku kufuneka kuqhutywe kuwo wonke umjikelo wobomi benkqubo ye-photovoltaic, ubuncinane iminyaka engama-20.

Ngo-1996, ngokusekelwe kwezi ndawo zesicelo kunye neemfuno zemarike, uhlobo olutsha lwe-plug-in connector lwenzeka.Esi siqhagamshelo sokuqala se-photovoltaic ngokwenene kwihlabathi-MC3.Umqambi wayo yinkampani yaseSwitzerland i-Multi-Contact (ngo-2002, edityaniswe kwi-Stäubli Group njengophawu lwesinxibelelanisi sombane), i-MC sisishunqulelo se-brand, kwaye u-3 ubukhulu bedayamitha engundoqo yesinyithi.Umzimba oyintloko we-MC3 wenziwe ngezinto ze-TPE (i-thermoplastic elastomer), kwaye uxhulumaniso lomzimba luphunyezwa ngokusebenzisa intsebenziswano.Okubaluleke ngakumbi, i-MC3 isebenzisa iteknoloji ye-MULTILAM kwinkqubo yayo yokudibanisa ukuqinisekisa ukuzinza okungapheliyo koqhagamshelwano.Kamva, abavelisi abaninzi bezonxibelelwano baxelisa iteknoloji ye-MULTILAM.

Ngo-2002, ukuzalwa kwe-multi-contact MC4 ikhonkco iphinda ichaze kwakhona i-photovoltaic connector, eyaqaphela ngokwenene "iplagi kunye nokudlala".Izinto zokugquma zisebenzisa i-PC/PA, kwaye ukuyila kulula ukuhlanganisa nokufaka kwisiza.Emva kokuba i-MC4 ye-multi-contact yafika kwimarike, yafumana ngokukhawuleza ukuqatshelwa kwemarike kwaye ngokuthe ngcembe yaba ngumgangatho we-photovoltaic connectors.Abavelisi abaninzi babiza izihlanganisi zabo "×× MC4".Ukuba ukhangela i-MC4 e-Alibaba, ungafumana malunga ne-44,000 yeemveliso ezinxulumeneyo, ezibonisa impembelelo enamandla yemarike ye-MC4.

I-MC4 iye yazisa ngokulandelelana i-MC4-Evo2 kunye ne-MC4-Evo3 uthotho njengoko imfuno yemarike itshintsha.Izixhumi ze-MC4 zechungechunge zinokuhlangabezana ngokupheleleyo neemfuno zabathengi kwiinkqubo ze-photovoltaic ze-1500V.

MC4 kunye ne "MC4-like"

Ii-multi-contact MC4 izihlanganisi zohlulwe zibe zeziphelo zocingo kunye neziphelo zebhodi.Ngokwesiqhelo, i-MC4 ekubhekiselwa kuyo ngumntu wonke ibhekisa kwiincam zocingo.I-MC4 inamalungu amabini: amalungu esinyithi kunye neendawo zokugquma.

Njengoko bekutshiwo ngaphambili, i-MC sisishunqulelo se-Multi-Contact, kwaye u-4 ubukhulu bedayamitha engundoqo yesinyithi.Ngoko ke, kwimarike yokudibanisa i-photovoltaic, ezininzi ezibizwa ngokuba yi-MC4s zifuna ukucaciswa kwakhona, kwaye zingabizwa ngokufanelekileyo ngokuthi "i-MC4-like".

Ngaphandle kokwahluka kwembonakalo ethile (efana nokumila/ilogo, njl.njl.), umahluko ongundoqo phakathi kwe-MC4 kunye ne-"MC4-like" kukuba kusetyenziswe iteknoloji ye-MULTILAM.I-teknoloji ye-MULTILAM inozinzo lwexesha elide, elinokuqinisekisa ukuba umnxibelelanisi ugcina ukuchasana okuphantsi koqhagamshelwano phakathi komjikelezo wobomi benkqubo ye-photovoltaic.

I-"MC4-like", ngezizathu zemarike, ibango lokuba idibana ne-MC4.Nangona kubonakala ngathi uxhulumaniso lugqityiwe, ingozi yokhuseleko efihliweyo sele yenzekile.Izixhumi zabavelisi abahlukeneyo azihambelani kwiinkcukacha, imilinganiselo kunye nokunyamezela, ngoko abanako ukuhambelana ne-100%.Ukuba ufaka ngenkani omnye komnye, kuya kubangela ukunyuka kweqondo lokushisa, utshintsho lokumelana noqhagamshelwano, kunye neengxaki ukuba ukulinganisa kwe-IP akunakuqinisekiswa, okuya kuchaphazela kakhulu ukuveliswa kwamandla kunye nokhuseleko lwabaxhamli.

Okubi nangakumbi kukuba xa kukho ingxaki, kusenokwenzeka ukuba ikhokelele kwiingxabano zomthetho.Njengoko imithetho nemimiselo echaphazelekayo ingagqibelelanga, uxanduva lweengxaki ezibangelwa kukufakela ngokulinganayo kusenokwenzeka ukuba luthwalwe ngumfaki wesikhululo samandla.

Ke ngoko, zombini i-TüV/UL kunye ne-Multi-Contact zikhuphe isiteyitimenti esithintela ukufakela okufanayo kweziqhagamshelo ezivela kubavelisi abohlukeneyo.

Imingcipheko yobuchwephesha ye-Multi-Contact MC4 Connectors

Kuvavanyo, ukuyila, ukuthenga, ukwakhiwa, ukwakhiwa kunye nokusebenza kunye nokugcinwa kwezixhobo zamandla e-photovoltaic, kukho imingcipheko engaqinisekanga (umgaqo-nkqubo / iteknoloji / indawo yendalo / imithetho, njl.).Ulawulo olungafanelekanga luya kuchaphazela ingeniso yeenkqubo ze-photovoltaic.

Ngokuthi gaizihlanganisi photovoltaiczixhalabile, imingcipheko yobugcisa iqulethwe kumgangatho, usetyenziso, ufakelo, nokusebenza nokugcinwa.

Kufuneka kucaciswe ukuba ingcambu yesizathu sokungaphumeleli kwe-PV isinxibelelanisi kunye nomlilo: kwimeko yokuhamba ngoku, ukuchasana koqhagamshelwano lomnxibelelanisi kwanda, okukhokelela ekunyuseni kweqondo lokushisa, elidlula iqondo lokushisa. uluhlu olunokuthi iqokobhe leplastiki kunye namalungu esinyithi anokumelana.
