Malo opweteka a photovoltaic mc4 cholumikizira cholumikizira: Crimping

Ndi chitukuko chofulumira cha kugawidwa, makamaka msika wa photovoltaic wapakhomo m'zaka zaposachedwa, mavuto amtundu wa photovoltaic systems akhala akudziwika kwambiri.Moto mu dongosolo la photovoltaic sudzangowononga chitetezo chaumwini, komanso udzakhala ndi zotsatira zoipa pamakampani.Malinga ndi malipoti ofufuza akunja, kuyika kolumikizira kolumikizana ndi kuyika kolumikizira kosakhazikika kumakhala chifukwa choyamba ndi chachitatu choyambitsa moto.Nkhaniyi ikufotokoza za kusanthula kusakhazikika kwa zolumikizira, makamaka crimping wa chingwe photovoltaic ndi cholumikizira zitsulo pachimake, kuti owerenga ndi buku lina, kusunga photovoltaic dongosolo, ndi kuteteza ubwino wa ogwiritsa.

Mkhalidwe Wamsika

Mu dongosolo la mphamvu ya photovoltaic, zolumikizira za photovoltaic zimagwiritsidwa ntchito makamaka mu zigawo, mabokosi ophatikizira, ma inverters ndi maulumikizidwe pakati pawo, omwe ambiri amaikidwa mu fakitale, ndipo khalidwe la crimp ndilodalirika.Pafupifupi 10% ya zolumikizira zotsalira ziyenera kuyikidwa pamanja pamalo a polojekiti, makamaka ponena za kufunika koyika zolumikizira kumapeto onse a chingwe cha photovoltaic cholumikiza chipangizo chilichonse.Malinga ndi zomwe zachitika zaka zambiri zoyendera makasitomala, chifukwa chosowa maphunziro a ogwira ntchito yoyika pamalowo komanso kugwiritsa ntchito zida zaukadaulo zaukadaulo, zolakwika za crimping ndizofala, monga tawonera pansipa.

Mitundu ndi mawonekedwe azitsulo zachitsulo

Chitsulo chachitsulo ndi thupi lalikulu la cholumikizira ndi njira yofunika kwambiri yoyendera.Pakalipano, zolumikizira zambiri za photovoltaic pamsika zimagwiritsa ntchito chitsulo chofanana ndi "U", chomwe chimasindikizidwa ndikupangidwa kuchokera papepala lamkuwa, lomwe limatchedwanso chitsulo chosindikizidwa.Chifukwa cha kupondaponda, chitsulo chooneka ngati "U" sichimangopanga bwino kwambiri, komanso chimatha kukonzedwa mu unyolo, womwe ndi woyenera kwambiri kupanga makina opangira mawaya.

Zolumikizira zina za photovoltaic zimagwiritsa ntchito chitsulo chofanana ndi "O", chomwe chimapangidwa ndi kubowola mabowo kumbali zonse ziwiri za ndodo yopyapyala yamkuwa, yomwe imatchedwanso chitsulo chopangidwa ndi makina.Pakatikati pazitsulo zooneka ngati "O" zitha kung'ambika payekhapayekha, zomwe sizoyenera kugwiritsidwa ntchito pazida zokha.

Chidziwitso choyambirira cha crimping

Crimping ndi imodzi mwazinthu zoyambira komanso zodziwika bwino zolumikizirana.Kuchuluka kwa crimping kumachitika tsiku lililonse.Panthawi imodzimodziyo, crimping yatsimikiziridwa kuti ndi teknoloji yolumikizana yokhwima komanso yodalirika.

Crimping ndondomeko

Kudalirika kwa crimping kumadalira kwambiri zida ndi ntchito, zomwe zimatsimikizira ngati zotsatira zomaliza za crimping zikukwaniritsa zofunikira za muyezo.Tengani chitsulo chowoneka ngati "U" monga chitsanzo.Kwenikweni ndizitsulo zamkuwa zokhala ndi tini ndipo zimafunika kulumikizidwa ndi chingwe cha photovoltaic mwa crimping.Njira ya crimping ndi iyi:

【Chithunzi 3: Njira ya Crimping】

Sikovuta kuona kuti "U"-woboola pakati zitsulo crimping ndi njira imene pamene crimping kutalika amachepetsa pang'onopang'ono (pamene crimping mphamvu pang'onopang'ono kuwonjezeka), pepala mkuwa wokutidwa ndi chingwe waya wamkuwa pang'onopang'ono wothinikizidwa.Mwanjira iyi, kuwongolera kutalika kwa crimping kumatsimikizira mwachindunji mtundu wa crimping.Kuwongolera kwa crimp wide sikofunikira kwambiri, chifukwa kufa kwa crimp kumatsimikizira kuchuluka kwake.

Kutalika kwa crimp

Anthu ambiri amadziwa kuti crimping yotayirira kwambiri kapena yothina kwambiri sibwino, kotero pamene crimping ikupita patsogolo, kodi kutalika kwa crimping kuyenera kuyendetsedwa bwanji?Kuonjezera apo, kodi zizindikiro ziwiri zofunika kwambiri, zomwe ndi kukoka mphamvu ndi magetsi, zimasintha bwanji panthawiyi?

[Chithunzi 4: Mphamvu yochotsa mphamvu ndi kutalika kwa crimp]

Pamene kutalika kwa crimping kumachepa pang'onopang'ono, mphamvu yokoka pakati pa chingwe ndi chitsulo chachitsulo idzawonjezeka pang'onopang'ono mpaka ifike pa "X" pa chithunzi pamwambapa.Ngati kutalika kwa crimping kukupitirirabe kuchepa, mphamvu yokoka idzapitirirabe kuchepa chifukwa cha kuwonongeka kwapang'onopang'ono kwa kapangidwe ka waya wamkuwa.

[Chithunzi 5: Conductivity ndi kutalika kwa crimp]

Chithunzi pamwambapa chikufotokoza za nthawi yayitali yamagetsi ya crimping.Kukula kwamtengo wapatali, kumapangitsa kuti magetsi azikhala bwino, komanso makhalidwe abwino a magetsi a chingwe ndi zitsulo zapakati pazitsulo."X" imayimira mfundo yabwino kwambiri.

Ngati ma curve awiri omwe ali pamwambawa alumikizidwa palimodzi, titha kupeza lingaliro losavuta:

        Thekutalika kwabwino kwa crimping kumatha kungokhala kulingalira mozama za mphamvu yokoka ndi kuwongolera, komanso mtengo wapakati pazigawo ziwiri zabwino kwambiri., monga momwe zilili pansipa.

Crimping quality kuwunika

Njira zowunikira zomwe zimagwiritsidwa ntchito kwambiri m'makampani ndi izi:

■ Kutalika kwa crimping / m'lifupi kumatha kuyezedwa ndi vernier caliper mkati mwazodziwika;

■ Mphamvu yokoka, ndiko kuti, mphamvu yofunikira kukoka kapena kuswa waya wamkuwa kuchokera kumalo otsekemera, monga chingwe cha 4mm2, IEC 60352-2 imafuna osachepera 310N;

■ Kukaniza, kutenga chingwe cha 4mm2 mwachitsanzo, IEC 60352-2 imafuna kukana pa crimp kukhala osachepera 135 microohms;

■ Kusanthula kwa magawo osiyanasiyana, kudula kosawononga kwa crimping zone, kusanthula m'lifupi, kutalika, kukakamiza, symmetry, ming'alu ndi ma burrs, ndi zina zotero.

Ngati ndi kumasula chipangizo chatsopano kapena crimping kufa watsopano, kuwonjezera pa mfundo pamwamba, m'pofunikanso kuwunika kukana bata pansi pa kutentha njinga mikhalidwe, kutanthauza muyezo IEC 60352-2.

Chida cha Crimping

Zolumikizira zambiri za photovoltaic zimayikidwa mufakitale kudzera pazida zokha, ndipo mtundu wa crimp ndi wapamwamba.Komabe, kwa zolumikizira zomwe ziyenera kukhazikitsidwa pamalo a polojekiti, crimping imatha kuchitidwa ndi ma crimping pliers.Ma crimping pliers oyambirira ayenera kugwiritsidwa ntchito popanga crimping.Ma pliers wamba kapena singano-nose pliers sangathe kugwiritsidwa ntchito popanga crimping.Kumbali imodzi, mtundu wa crimping ndi wotsika, ndipo iyinso ndi njira yosazindikirika ndi opanga zolumikizira ndi mabungwe otsimikizira.

Zowopsa za crimping mosakhazikika

Kusakhazikika bwino kungayambitse kusatsatira zomwe zanenedwa, kusakhazikika kwa kulumikizana, komanso kulephera kusindikiza.Ndichiwopsezo chachikulu chomwe chimakhudza ntchito yonse komanso phindu la magetsi a photovoltaic.

Chidule

■ Cholumikizira ndi gawo laling'ono, koma lidzakhudza kugwira ntchito kwa polojekiti ya photovoltaic.Kugwirizana ndi khalidwe nthawi zambiri kumatanthauza kutayika kwakukulu ndi zoopsa zomwe zikanapewedwa;

■ Kuyika ma photovoltaic connectors, crimping link ndiyofunika kwambiri, ndipo tikulimbikitsidwa kugwiritsa ntchito zipangizo zamakono.Kwa okhazikitsa mainjiniya, maphunziro a crimping ndi ulalo wofunikira.
