Chingwe cha Solar DC

Zingwe zambiri za DC m'malo opangira magetsi adzuwa ziyenera kuyikidwa panja, ndipo chilengedwe ndi chovuta.Zida za chingwe ziyenera kukhazikitsidwa pa kukana kwa kuwala kwa ultraviolet, ozoni, kusintha kwakukulu kwa kutentha ndi kukokoloka kwa mankhwala.Kugwiritsa ntchito nthawi yayitali zinthu wamba m'malo awa kumapangitsa kuti chingwe cha chingwe chikhale chofooka komanso kuwola kutsekereza chingwe.Izi zidzawononga mwachindunji dongosolo la chingwe, ndipo nthawi yomweyo zidzawonjezera chiopsezo cha chingwe chachifupi.Pakatikati ndi nthawi yayitali, kuthekera kwa moto kapena kuvulala kwaumwini kumakhalanso kwakukulu, zomwe zimakhudza kwambiri moyo wautumiki wa dongosolo.

Chifukwa chake,ndikofunikira kwambiri kugwiritsa ntchitozingwe za solar dcndi zigawo zikuluzikulu za magetsi a dzuwa.Zingwe zapadera za photovoltaic ndi zigawo zake sizimangokhala ndi kukana kwabwino kwa mphepo ndi mvula, UV ndi ozoni kukokoloka, komanso zimatha kupirira kusintha kwakukulu kwa kutentha (mwachitsanzo: kuchokera -40 mpaka 125 ° C).Ku Ulaya, amisiri apambana mayeso ndipo kutentha kwake padenga kumakhala kokwera mpaka 100-110 ° C.

Momwe mungasankhire Zingwe za Solar DC za Zomera Zopangira Mphamvu za Dzuwa?

Kuchokera pa Cable conductor material:

Nthawi zambiri, zingwe za DC zomwe zimagwiritsidwa ntchito m'malo opangira magetsi a dzuwa zimagwiritsidwa ntchito panja kwa nthawi yayitali.Chifukwa cha kuchepa kwa zomangamanga, zolumikizira zimagwiritsidwa ntchito kwambiri polumikizira chingwe.Zipangizo zopangira chingwe zitha kugawidwa kukhala pachimake chamkuwa ndi pachimake cha aluminium.Copper core cable ili ndibwino makutidwe ndi okosijeni kukana kuposa aluminiyamu, moyo wautali, kukhazikika bwino, kutsika kwamagetsi otsikandikutayika kwa mphamvu zochepa;pomanga, chifukwa pachimake mkuwa ndi kusinthasintha ndi lololeka bend utali wozungulira ndi yaing'ono, ndi yabwino kutembenuka ndi kudutsa chitoliro;ndipo pachimake mkuwa ndi kugonjetsedwa ndi kutopa ndi kupindika mobwerezabwereza si kophweka kusweka, kotero mawaya ndi yabwino;nthawi yomweyo, pachimake mkuwa ali mkulu mawotchi mphamvu ndipo akhoza kupirira mavuto aakulu mawotchi, amene amabweretsa yabwino kwambiri yomanga ndi anagona, ndipo amalenga zinthu zomanga makina.M'malo mwake, zingwe zoyambira za aluminiyamu ndizomakonda kukhala okosijeni(electrochemical reaction) pamalumikizidwe oyika chifukwa cha mankhwala a aluminiyamu, makamaka zochitika zokwawa, zomwe zimatha kuyambitsazolephera.

Choncho, zingwe zamkuwa zili ndi ubwino wapadera wogwiritsa ntchito magetsi a dzuwa, makamaka m'munda wamagetsi okwiriridwa mwachindunji.Ikhoza kuchepetsa ngozi, kupititsa patsogolo kudalirika kwa magetsi, ndipo ndi yabwino kumanga, kugwira ntchito ndi kukonza.Ichi ndi chifukwa chake zingwe zamkuwa zimagwiritsidwa ntchito kwambiri pamagetsi apansi pansi ku China.

Ubwino wa zingwe zamagetsi zamagetsi:

Kutentha kwakukulu, kukana kuzizira, kukana kwamafuta, asidi ndi mchere wamchere, kukana kwa UV, kutentha kwamoto, kuteteza chilengedwe., zingwe zamagetsi zamagetsi zimagwiritsidwa ntchito makamaka m'malo ovuta kwambiri okhala ndi moyo wautumiki woposa25 zaka.

Zingwe zadzuwa nthawi zambiri zimakhala padzuwa, ndipo ma solar a dzuwa amagwiritsidwa ntchito nthawi zambiri m'malo ovuta, mongakutentha kochepandicheza cha ultraviolet.Kunyumba kapena kunja, nyengo ikakhala yabwino, kutentha kwambiri kwa dzuŵa kumakhala kokwera kwambiri mpaka 100 ℃.The zipangizo zosiyanasiyana kuti angagwiritsidwe ntchito zingwe wamba ndi apamwamba interwoven kugwirizana zipangizo monga polyvinyl kolorayidi (PVC), mphira, TPE ndi XLPE, koma chisoni kuti kutentha oveteredwa kwambiri zingwe wamba Komanso, ngakhale PVC insulated zingwe zokhala ndi kutentha kwa 70 ° C nthawi zambiri zimagwiritsidwa ntchito panja, koma sizingakwaniritse zofunikira za kutentha kwambiri, chitetezo cha UV, komanso kuzizira.Zitha kuwoneka kuti malo opangira magetsi a dzuwa ayenera kusankha zingwe zodalirika za solar dc.

Ubwino wake of slocable zingwe za solar dc

Kodi pali kusiyana kotani pakati pa zingwe za Normal DC ndi zingwe za Solar DC?

Kuchokera pamawonekedwe a chingwe chotchinjiriza sheath zakuthupi:

	Zingwe zachizolowezi za DC	Zingwe za Solar DC
kutsekereza	Kusungunula kwa polyolefin yolumikizidwa ndi waya	PVC kapena XLPE insulation
jekete	Kusungunula kwa polyolefin yolumikizidwa ndi waya	Chithunzi cha PVC

Panthawi yoika ndi kugwiritsira ntchito ndi kukonza malo opangira magetsi a dzuŵa, zingwe zimatha kuthamangitsidwa m'nthaka pansi pa nthaka, zodzaza ndi udzu ndi miyala, m'mphepete mwa denga la denga, ndi kuwululidwa ndi mpweya.Zingwezo zimatha kukhala ndi mphamvu zosiyanasiyana zakunja.Ngati chingwe sheath sichili cholimba mokwanira,chingwe chotchinga chingwe chidzawonongeka, chomwe chidzakhudza moyo wautumiki wa chingwe chonse, kapena chifukwapafupipafupi, moto,ndingozi zovulaza munthu.Kafukufuku wa sayansi yama chingwe ndi akatswiri aukadaulo adapeza kuti zinthu zomwe zimalumikizidwa ndi ma radiation zimakhala ndi mphamvu zamakina apamwamba kuposa kale mankhwala a radiation.Njira yolumikizirana yolumikizirana imasintha kapangidwe kake ka polima wa chingwe chotchinjiriza sheath zakuthupi, fusible thermoplastic zakuthupi zimasinthidwa kukhala zinthu zopanda fusible elastomeric, ndipo ma radiation olumikizana nawo amathandizira kwambiri matenthedwe, makina ndi magetsi a chingwe. Insulation zakuthupi.Mankhwala katundu.

Dongosolo la DC nthawi zambiri limakhudzidwa ndi zinthu zosiyanasiyana zosasangalatsa panthawi yogwira ntchito, zomwe zimapangitsa kuti pakhale pansi, zomwe zimapangitsa kuti dongosololi lisagwire ntchito moyenera.Monga kutulutsa, kupanga ma waya osakwanira, zida zotchingira zosayenerera, kutsika kwapang'onopang'ono, kukalamba kwamagetsi a DC system, kapena kuwonongeka kwina komwe kungayambitse kutsika kapena kukhala chowopsa.

Kuchokera pamawonekedwe a kukana katundu wa makina:

Kwa zingwe za solar dc, pakuyika ndi kugwiritsa ntchito, zingwe zimatha kuyendetsedwa pamphepete lakuthwa kwa denga.Pa nthawi yomweyo, zingwe ayenera kupirirakupanikizika, kupinda, kupsinjika, kukankhana kukankhana katundundikukana kwambiri kukhudza, yomwe ili yabwino kuposa zingwe za dc.Ngati mugwiritsa ntchito zingwe za dc wamba, sheath ilikusowa kwa UV chitetezo ntchito, zomwe zidzapangitse kuti chipolopolo chakunja cha chingwe chikhale chokalamba, chomwe chidzakhudza moyo wautumiki wa chingwe, zomwe zingayambitse maonekedwe afupikitsa, ma alarm amoto, ndi kuvulala koopsa kwa ogwira ntchito.

Pambuyo poyatsidwa, solar dc cable insulation sheath imakhala ndi mphamvu yolimbana ndi kutentha kwambiri, kukana kwa radiation ya ultraviolet, kukana mafuta, komanso kuzizira.Moyo wautumiki ndi zaka zopitilira 25, zomwe sizingafanane ndi zingwe zamba za dc.
