Iphoyinti lobuhlungu lokufakwa kwesixhumi se-photovoltaic mc4: I-Crimping

Ngokuthuthuka okusheshayo kwemakethe esakazwayo, ikakhulukazi yasendlini ye-photovoltaic eminyakeni yamuva, izinkinga zekhwalithi yezinhlelo ze-photovoltaic ziye zavela kakhulu.Umlilo ohlelweni lwe-photovoltaic ngeke nje ubeke engozini ukuphepha komuntu siqu, kodwa futhi ube nomthelela omubi embonini.Ngokwemibiko yocwaningo lwangaphandle, ukufakwa kwesixhumanisi esihlanganyelwe kanye nokufakwa kwesixhumi okungajwayelekile kulinganisa imbangela yokuqala neyesithathu yomlilo.Lesi sihloko sigxile ekuhlaziyweni kokufakwa okungajwayelekile kwezixhumi, ikakhulukazi ukumiswa kwekhebula le-photovoltaic kanye nengqikithi yensimbi yesixhumi, ukuze kunikezwe abasebenzisi ireferensi ethile, kugcinwe isistimu ye-photovoltaic, nokuvikela izinzuzo zabasebenzisi.

Isimo Semakethe

Kuhlelo lokukhiqiza amandla e-photovoltaic, izixhumi ze-photovoltaic zisetshenziswa ikakhulukazi ezingxenyeni, amabhokisi okuhlanganisa, ama-inverters nokuxhumana phakathi kwawo, iningi lawo elifakwe efektri, futhi ikhwalithi ye-crimp inokwethenjelwa.Cishe u-10% wezixhumi ezisele zidinga ukufakwa mathupha endaweni yephrojekthi, ikakhulukazi ebhekisela esidingweni sokufaka izixhumi kuzo zombili iziphetho zekhebula le-photovoltaic elixhuma idivayisi ngayinye.Ngokusho kokuhlangenwe nakho kweminyaka eminingi yokuvakasha kwamakhasimende, ngenxa yokuntuleka kokuqeqeshwa kwabasebenzi bokufaka endaweni kanye nokusetshenziswa kwamathuluzi ochwepheshe be-crimping, ukungahambi kahle kwe-crimping kuvamile, njengoba kuboniswe ngezansi.

Izinhlobo nezici zensimbi yensimbi

Ingqikithi yensimbi iyindikimba eyinhloko yesixhumi kanye nendlela yokugeleza ebaluleke kakhulu.Njengamanje, inqwaba yezixhumi ze-photovoltaic emakethe zisebenzisa i-core yensimbi efana ne-"U", egxiviziwe futhi yakhiwe kusuka eshidini lethusi, elaziwa nangokuthi ingqikithi yensimbi enesitembu.Ngenxa yenqubo yokugxiviza, umgogodla wensimbi omise okwe-“U” awugcini nje ngokusebenza kahle kakhulu ekukhiqizeni, kodwa futhi ungahlelwa ngeketango, elifaneleka kakhulu ukukhiqizwa kwezintambo zocingo ezizenzakalelayo.

Ezinye izixhumi ze-photovoltaic zisebenzisa umgogodla wensimbi omise okwe-“O”, owakhiwa ngokubhoboza izimbobo kuzo zombili iziphetho zenduku yethusi encane, ebizwa nangokuthi i-machined metal core.Umongo wensimbi omise okuka-“O” ungacwiliswa ngawodwana kuphela, ongafanele ukusetshenziswa emishinini ezenzakalelayo.

【Isithombe 2: Uhlobo lwe-Metal core】

Kukhona futhi umgogodla wensimbi ongavamile kakhulu ongenawo ama-crimp, oxhunywe kukhebula ngeshidi lasentwasahlobo.Njengoba kungekho mathuluzi okugaya adingekayo, ukufakwa kulula futhi kulula.Kodwa-ke, ukuxhumeka kweqabunga lentwasahlobo kuzoholela ekuphikiseni okukhulu kokuxhumana, futhi ukwethembeka kwesikhathi eside akukwazi ukuqinisekiswa.Ezinye izinhlangano zokunikeza izitifiketi nazo azilugunyazi lolu hlobo lwensimbi ewumgogodla.

Ulwazi oluyisisekelo lwe-crimping

I-Crimping ingenye yezindlela eziyisisekelo nezijwayelekile zokuxhuma.I-crimping eminingi iyenzeka nsuku zonke.Ngesikhathi esifanayo, i-crimping ifakazelwe njengobuchwepheshe bokuxhuma obuvuthiwe nobuthembekile.

Inqubo ye-crimping

Ukuthembeka kwe-crimping kuncike kakhulu kumathuluzi nokusebenza, kokubili okunquma ukuthi umphumela wokugcina wokugoqa uyahlangabezana yini nezimfuneko zezinga.Thatha ingqikithi yensimbi emise okuka-“U” njengesibonelo.Ngokuyisisekelo i-copper tin-plated material futhi idinga ukuxhunywa kukhebula le-photovoltaic ngokufaka i-crimping.Inqubo ye-crimping imi kanje:

【Isithombe 3: Inqubo ye-Crimping】

Akunzima ukubona ukuthi i-crimping yensimbi emise okwe-“U” iyinqubo lapho ukuphakama kwe-crimping kuncipha kancane kancane (ngenkathi amandla e-crimping akhula kancane kancane), ishidi lethusi eligoqwe ngentambo yethusi licindezelwa kancane kancane.Kule nqubo, ukulawula ukuphakama kwe-crimping kunquma ngokuqondile ikhwalithi ye-crimping.Ukulawulwa kobubanzi be-crimp akubalulekile kakhulu, ngoba ukufa kwe-crimp kunquma inani lobubanzi.

Ukuphakama kwe-crimp

Abantu abaningi bayazi ukuthi ukukhwabanisa okuxekethile noma okumpintsha kakhulu akukuhle, ngakho-ke njengoba i-crimping iqhubeka, ubude be-crimping kufanele bulawule kangakanani?Ngaphezu kwalokho, izinkomba ezimbili ezibalulekile zekhwalithi, okungukuthi amandla okudonsa kanye ne-conductivity kagesi, zishintsha kanjani phakathi nale nqubo?

[Umfanekiso 4: Amandla okudonsa kanye nokuphakama kwe-crimp]

Njengoba ukuphakama kwe-crimping kuncipha kancane kancane, amandla okudonsa phakathi kwekhebula nomgogodla wensimbi azokhula kancane kancane aze afinyelele iphuzu elithi "X" esithombeni esingenhla.Uma ukuphakama kwe-crimping kuqhubeka nokuncipha, amandla okudonsa azoqhubeka nokuncipha ngenxa yokubhujiswa kancane kancane kwesakhiwo socingo lwethusi.

[Umfanekiso 5: I-Conductivity kanye nokuphakama kwe-crimp]

Umfanekiso ongenhla uchaza izici zikagesi zesikhathi eside ze-crimping.Uma inani elikhulu, i-conductivity kagesi iba ngcono, futhi kuba ngcono izici zikagesi zekhebula kanye noxhumano oluyisisekelo lwensimbi.U-“X” umele iphuzu elingcono kakhulu.

Uma amajika amabili angenhla ebekwe phezulu ndawonye, ​​singathola isiphetho kalula:

        Iukuphakama okungcono kakhulu kokugwedla kungaba kuphela ukucatshangelwa okuphelele kwamandla okudonsa kanye ne-conductivity, kanye nenani endaweni ephakathi kwamaphuzu amabili angcono kakhulu., njengoba kuboniswe ngezansi.

Crimping izinga ukuhlolwa

Izindlela zokwahlulela ezivame ukusetshenziswa embonini yilezi ezilandelayo:

■ Ubude/ububanzi be-crimping bungalinganiswa nge-vernier caliper ngaphakathi kwebanga elichaziwe;

■ Amandla okudonsa, okungukuthi, amandla adingekayo ukuze adonse noma aphule intambo yethusi endaweni yokugoqa, njengekhebula elingu-4mm2, IEC 60352-2 idinga okungenani i-310N;

■ Ukumelana, ukuthatha intambo engu-4mm2 njengesibonelo, i-IEC 60352-2 idinga ukumelana ne-crimp kube ngaphansi kwama-microohms angu-135;

■ Ukuhlaziywa kwezigaba ezihlukene, ukusika okungabhubhisi indawo yokugezela, ukuhlaziya ububanzi, ubude, izinga lokucindezela, ukulinganisa, ukuqhekeka nama-burrs, njll.

Uma izokhipha idivayisi entsha noma i-crimping die entsha, ngaphezu kwamaphuzu angenhla, kuyadingeka futhi ukuqapha ukuzinza kokumelana ngaphansi kwezimo zokushisa zamabhayisikili, bheka i-IEC 60352-2 evamile.

Ithuluzi le-crimping

Iningi lezixhumi ze-photovoltaic zifakwe efekthri ngemishini ezenzakalelayo, futhi ikhwalithi ye-crimp iphezulu.Kodwa-ke, kwizixhumi okufanele zifakwe endaweni yephrojekthi, ukukhwabanisa kungenziwa kuphela nge-crimping pliers.Iphinifa le-crimping lasekuqaleni kufanele lisetshenziswe ekugwebeni.Iphinifa elivamile le-vise noma inaliti-nose ayikwazi ukusetshenziselwa ukugoqa.Ngakolunye uhlangothi, ikhwalithi ye-crimping iphansi, futhi lena futhi indlela engaziwa abakhiqizi bezixhumi nama-ejensi wokunikeza izitifiketi.

Izingozi ezingavamile zokugoqa

Ukugwetshwa kabi kungase kuholele ekungathobelini izicaciso, ukumelana nokuxhumana okungazinzile, kanye nokwehluleka ukuvala.Kuyiphuzu elikhulu lengozi elithinta umsebenzi jikelele kanye nenzuzo yezitshalo zamandla e-photovoltaic.

Isifinyezo

■ Isixhumi siyingxenye encane, kodwa sizothinta ukusebenza kahle kwephrojekthi ye-photovoltaic.Ukuyekethisa ngekhwalithi ngokuvamile kusho ukulahlekelwa okuphezulu okulandelayo kanye nezingozi, obekungagwenywa;

■ Ukuze kufakwe izixhumi ze-photovoltaic, isixhumanisi se-crimping sibaluleke kakhulu, futhi kunconywa ukusebenzisa amathuluzi ochwepheshe be-crimping.Kubafaki bonjiniyela, ukuqeqeshwa kwe-crimping kuyisixhumanisi esibalulekile.
