Ukuhunyushwa Okuningiliziwe: Izixhumi ze-MC4 Zokuxhumana Okuningi

I-MC4 ayiyona into engaziwa kubasebenzi be-photovoltaic, icishe ifane nezixhumi ze-photovoltaic.Iisixhumi se-MC4 esithinta abaningiingatholakala ezingxenyeni ezibalulekile zokukhiqiza amandla e-photovoltaic njengamamojula, amabhokisi okuhlanganisa kanye nama-inverters, futhi banesibopho sokuxhumeka okuphumelelayo kwesiteshi samandla.

Ekupheleni kuka-2015, umthamo we-photovoltaic waseChina ohlanganisiwe wawungu-43.18GW, ukleliswe kuqala emhlabeni.Kubalwe ngesisekelo samasethi angaba ngu-4,200 ezixhumi ze-photovoltaic ezisetshenziswa ku-1MW, okwamanje kunamasethi ezixhumi angaba yizigidi eziyi-180 afakwe e-China.Ngokombono wobungozi, kusho ukuthi okungenani kunezindawo zobungozi eziyizigidi eziyi-180 okudingeka ziqashwe ngabanikazi beziteshi zikagesi abehlukene.

Noma kunjalo, le ngxenye encane ivame ukunganakwa phakathi nezigaba zokuklama, ukwakhiwa, nokusebenza nokunakekelwa kwesiteshi sikagesi.Isizathu sihlobene kakhulu nokuqonda kwawo wonke umuntu nge-MC4.

Mhlawumbe yisikhathi sokwazi isixhumi se-MC4 yokuxhumana nabantu abaningi futhi.

Umlando omfushane wezixhumi zelanga

Ezixhunyweni eziningi ze-MC4 zokuxhumana, u-1996 no-2002 iminyaka emibili ebaluleke kakhulu.Lawa maphuzu amabili ngesikhathi aphinde ahambisane nezindawo ezibalulekile zokuthuthukiswa kwemboni ye-photovoltaic.Nakuba i-MC4 ye-multi-contact ayizange ihambisane nemboni ye-photovoltaic, ukubonakala kwayo kukhuthaze kakhulu ukwanda okusheshayo kokufakwa kwe-photovoltaic.

Ngaphambi kuka-1996, izintambo ze-photovoltaic zazixhunywe ngamatheminali angama-screw noma ukuxhumana kwe-splice.Ngokukhula kwenani lezinhlelo ze-photovoltaic ezifakiwe, imboni inesidingo esinamandla esikhulayo sezixazululo zokuxhuma okusheshayo, eziphephile nezisebenziseka kalula.

        Ngenxa yokuthi uhlelo lwe-photovoltaic luvezwa umoya, imvula, ilanga elishisayo kanye noshintsho okushisa okwedlulele isikhathi eside, isixhumi selanga kufanele sikwazi ukuzivumelanisa nalezi zindawo ezinzima.Akufanele nje zivikeleke emanzini, zimelane nezinga lokushisa eliphezulu futhi zimelane nesimo sezulu emisebeni ye-ultraviolet, kodwa futhi zivikeleke ekuthinteni, umthamo wamanje wokuthwala ophezulu nokusebenza kahle okuphezulu.Ngesikhathi esifanayo, ukumelana nokuxhumana okuphansi nakho kuwukucatshangelwa okubalulekile.Konke lokhu kufanele kudlule kuwo wonke umjikelezo wokuphila wesistimu ye-photovoltaic, okungenani iminyaka engu-20.

Ngo-1996, ngokusekelwe kulezi zindawo zohlelo lokusebenza kanye nezidingo zemakethe, uhlobo olusha lwesixhumi se-plug-in lwaba khona.Lesi isixhumi sokuqala se-photovoltaic ngempela emhlabeni-MC3.Umsunguli wayo yinkampani yaseSwitzerland i-Multi-Contact (ngo-2002, ehlanganiswe ne-Stäubli Group njengophawu lwayo lwesixhumi sikagesi), i-MC isifinyezo somkhiqizo, futhi u-3 ungusayizi wobubanzi bomgogodla wensimbi.Umzimba oyinhloko we-MC3 wenziwe ngezinto ze-TPE (i-thermoplastic elastomer), futhi ukuxhumana ngokomzimba kufinyelelwa ngokubambisana okungqubuzanayo.Okubaluleke nakakhulu, i-MC3 isebenzisa ubuchwepheshe be-MULTILAM ohlelweni lwayo lokuxhuma ukuze kuqinisekiswe ukuzinza okuhlala njalo kokuxhumeka.Kamuva, abakhiqizi abaningi bezixhumi balingisa ubuchwepheshe be-MULTILAM.

Ngo-2002, ukuzalwa kwesixhumi se-MC4 esixhumene nabantu abaningi sichaza kabusha isixhumi se-photovoltaic futhi, esaqaphela ngempela "ipulaki nokudlala".Izinto ezifaka i-insulating zisebenzisa i-PC/PA, futhi ukwakheka kulula ukukuhlanganisa nokufaka esizeni.Ngemuva kokuthi i-MC4 yokuxhumana nabantu abaningi ifike emakethe, yasheshe yaqashelwa emakethe futhi kancane kancane yaba indinganiso yezixhumi ze-photovoltaic.Abakhiqizi abaningi babiza izixhumi zabo ngokuthi "××MC4".Uma usesha i-MC4 e-Alibaba, ungathola cishe imikhiqizo ehlobene engu-44,000, ebonisa ithonya elinamandla lemakethe le-MC4.

I-MC4 yethule ngokulandelana uchungechunge lwe-MC4-Evo2 kanye ne-MC4-Evo3 njengoba isidingo semakethe sishintsha.Izixhumi zochungechunge lwe-MC4 zingahlangabezana ngokugcwele nezidingo zamakhasimende kumasistimu we-photovoltaic angu-1500V.

I-MC4 kanye ne-"MC4-like"

Izixhumi ze-MC4 ezixhumene kakhulu zihlukaniswe ngezintambo neziphetho zebhodi.Ngomqondo ojwayelekile, i-MC4 okukhulunywa ngayo yiwo wonke umuntu ibhekisela ekugcineni kwezintambo.I-MC4 iqukethe izingxenye ezimbili: izingxenye zensimbi nezingxenye ezivikelayo.

Njengoba kushiwo ngaphambili, i-MC iyisifinyezo se-Multi-Contact, futhi u-4 usayizi wobubanzi bomgogodla wensimbi.Ngakho-ke, emakethe yesixhumi se-photovoltaic, eziningi ezibizwa ngokuthi ama-MC4 zidinga ukucaciswa kabusha, futhi zingase zibizwe ngokufaneleke kakhulu ngokuthi "i-MC4-like".

Ngaphandle komehluko othile wokubukeka (njengomumo/ilogo, njll.), umehluko oyinhloko phakathi kwe-MC4 kanye ne-"MC4-like" ukuthi kufanele kusetshenziswe ubuchwepheshe be-MULTILAM.Ubuchwepheshe be-MULTILAM bunozinzo lwesikhathi eside, olungaqinisekisa ukuthi isixhumi sigcina ukumelana nokuxhumana okuphansi okuqhubekayo kulo lonke umjikelezo wokuphila wesistimu ye-photovoltaic.

I-"MC4-like", ngenxa yezizathu zemakethe, ithi ihlangana ne-MC4.Yize kubukeka sengathi ukuxhumeka kuqediwe, ingozi efihliwe yokuvikela isivele yenzekile.Izixhumi zabakhiqizi abahlukene azihambisani nokucaciswa, ubukhulu kanye nokubekezelelana, ngakho azikwazi ukufaniswa no-100%.Uma nifakana ngenkani, kuzodala ukukhuphuka kwezinga lokushisa, izinguquko zokumelana nokuxhumana, kanye nezinkinga ukulinganisa kwe-IP okungenakuqinisekwa ngakho, okuzophazamisa kakhulu ukusebenza kahle kokukhiqizwa kwamandla nokuphepha kweziphikisayo.

Okubi kakhulu ukuthi uma kunenkinga maningi amathuba okuthi kuholele ezingxabanweni zezomthetho.Njengoba imithetho efanele nezimiso zingaphelele, umthwalo wemfanelo wezinkinga ezibangelwa ukufakwa okufanayo cishe uzothwalwa isifaki sesiteshi sikagesi.

Ngakho-ke, kokubili i-TüV/UL ne-Multi-Contact zikhiphe isitatimende esivimbela ukufakwa ngokufanayo kwezixhumi ezivela kubakhiqizi abahlukene.

Izingozi zobuchwepheshe ze-Multi-Contact MC4 Connectors

Ekuhlolweni, ekuklanyweni, ekuthengeni, ekwakhiweni, ekwakhiweni nasekusetshenzisweni nasekugcinweni kwemishini yamandla e-photovoltaic, kunezingozi ezingaqinisekile (inqubomgomo/ubuchwepheshe/imvelo/imithetho yemvelo, njll.).Ukulawula okungalungile kuzothinta imali engenayo yezinhlelo ze-photovoltaic.

Kuze kufikeizixhumi ze-photovoltaicezithintekayo, izingozi zobuchwepheshe zifakwe kwikhwalithi, isicelo, ukufakwa, nokusebenza nokugcinwa.

Kudingeka kuphawulwe ukuthi imbangela eyinhloko yokuhluleka kwesixhumi se-PV nomlilo yilezi: esimweni sokugeleza kwamanje, ukumelana nokuxhumana kwesixhumi kuyanda, okuholela ekwandeni kokukhuphuka kwezinga lokushisa, okudlula izinga lokushisa. ububanzi obungamelana negobolondo lepulasitiki nezingxenye zensimbi.
