Chingwe Chotetezedwa ndi Mineral Insulated (MICC kapena MI cable), monga mtundu wapadera wa chingwe, chimagwiritsidwa ntchito kwambiri m'mbali zonse za moyo chifukwa cha kukana kwake moto, kukana dzimbiri komanso kukhazikika kwa kufalikira kwa magetsi. Pepalali lifotokoza mwatsatanetsatane kapangidwe kake, mawonekedwe ake, malo ogwiritsira ntchito, momwe msika ulili komanso kuthekera kwa chitukuko cha chingwe chotetezedwa ndi mchere.
1. Kapangidwe ndi zinthu zake
Chingwe chotetezedwa ndi mchere chimapangidwa makamaka ndi waya wa copper conductor core, magnesium oxide powder insulation layer ndi copper sheath (kapena aluminiyamu sheath). Pakati pawo, waya wa conductor conductor core umagwiritsidwa ntchito ngati njira yotumizira mphamvu, ndipo magnesium oxide powder imagwiritsidwa ntchito ngati inorganic insulation material kuti ipatule conductor ndi sheath kuti zitsimikizire kuti chingwe chikugwira ntchito bwino komanso chitetezo. Gawo lakunja lingasankhidwe malinga ndi zosowa za chogwirira choyenera choteteza, kuti chiwonjezere chitetezo cha chingwe.
Makhalidwe a chingwe chotetezedwa ndi mchere amaonekera makamaka m'mbali zotsatirazi:
(1) Kukana moto kwambiri: Popeza kuti chotchingiracho chimapangidwa ndi zinthu zopangidwa ndi mchere monga magnesium oxide, zingwe zotchingira mchere zimatha kusungabe chitetezo chabwino pa kutentha kwambiri ndikuletsa moto. Chigoba chake cha mkuwa chimasungunuka pa 1083 ° C, ndipo chotchingira mchere chimathanso kupirira kutentha kwambiri kuposa 1000 ° C.
(2) Kukana dzimbiri kwambiri: chubu cha mkuwa chopanda msoko kapena chubu cha aluminiyamu ngati chinthu chopangira m'chikwama, kotero kuti chingwe chotetezedwa ndi mchere chimakhala ndi kukana dzimbiri kwambiri, chingagwiritsidwe ntchito m'malo ovuta kwa nthawi yayitali.
(3) Kukhazikika kwa ma transmission: Chingwe chotetezedwa ndi mchere chili ndi magwiridwe antchito abwino kwambiri otumizira ma transmission, oyenera mtunda wautali, kutumiza deta mwachangu komanso kutumiza mphamvu yamagetsi amphamvu komanso zochitika zina. Chili ndi mphamvu yayikulu yonyamulira ma current, kulephera kwakukulu kwa ma short-circuit, ndipo chimatha kutumiza ma current okwera pa kutentha komweko.
(4) Nthawi yayitali yogwira ntchito: chifukwa cha kukana moto, kukana dzimbiri ndi zina, nthawi yayitali yogwira ntchito ya zingwe zotetezedwa ndi mchere ndi yayitali, nthawi zambiri mpaka zaka pafupifupi 70.
2. Gawo la mapulogalamu
Zingwe zoteteza mchere zimagwiritsidwa ntchito kwambiri m'mbali zonse za moyo, makamaka kuphatikizapo:
(1) Nyumba zazitali: zimagwiritsidwa ntchito powunikira zinthu wamba, kuunikira kwadzidzidzi, alamu yamoto, mizere yamagetsi yamoto, ndi zina zotero, kuti zitsimikizire kuti magetsi abwinobwino akadalipo pakagwa ngozi.
(2) Makampani opanga mafuta: M'malo omwe angakhale oopsa kuphulika, kukana moto kwambiri komanso kukana dzimbiri kwa zingwe zotetezedwa ndi mchere zimapangitsa kuti zikhale zabwino kwambiri.
(3) Mayendedwe: Mabwalo a ndege, ngalande zapansi panthaka, zombo ndi malo ena, zingwe zoteteza mchere zimagwiritsidwa ntchito powunikira mwadzidzidzi, makina owunikira moto, mizere yopumira mpweya, ndi zina zotero, kuti zitsimikizire kuti malo oyendera magalimoto akugwira ntchito bwino.
(4) Malo ofunikira: monga zipatala, malo osungira deta, zipinda zowongolera moto, ndi zina zotero, ali ndi zofunikira kwambiri kuti magetsi azigwira bwino ntchito komanso kuti moto uziyenda bwino, ndipo zingwe zoteteza mchere ndizofunikira kwambiri.
(5) Malo apadera: ngalande, pansi pa nyumba ndi malo ena otsekedwa, chinyezi, kutentha kwambiri, kukana moto wa chingwe, kukana dzimbiri ndi kwakukulu, chingwe chotetezedwa ndi mchere chimatha kukwaniritsa zosowa izi.
3. Mkhalidwe wa msika ndi chiyembekezo cha chitukuko
Chifukwa cha kusamala kwambiri za chitetezo cha moto, kufunikira kwa msika wa zingwe zotetezedwa ndi mchere kukukulirakulira. Makamaka m'mapulojekiti a mphamvu zongowonjezwdwanso monga dzuwa ndi mphepo, zingwe zotetezedwa ndi mchere zimagwiritsidwa ntchito kwambiri chifukwa cha mphamvu zawo zosapsa ndi moto. Zikuyembekezeka kuti pofika chaka cha 2029, kukula kwa msika wa zingwe zotetezedwa ndi mchere padziko lonse lapansi kudzafika $2.87 biliyoni, ndi kuchuluka kwa kukula kwa pachaka (CAGR) kwa compound annual rate (CAGR) ya 4.9%.
Msika wa m'dziko muno, pogwiritsa ntchito miyezo monga GB/T50016, kugwiritsa ntchito zingwe zoteteza ku mineral mu zingwe zozimitsira moto kwakhala kofunikira, zomwe zalimbikitsa chitukuko cha msika. Pakadali pano, zingwe zamagetsi zoteteza ku mineral zili m'gulu lalikulu la msika, ndipo zingwe zotenthetsera zoteteza ku mineral zikukulitsa pang'onopang'ono kuchuluka kwa ntchito zomwe zimagwiritsidwa ntchito.
4. Mapeto
Chingwe choteteza ku moto chomwe chili ndi mchere chimagwira ntchito yofunika kwambiri m'mbali zonse za moyo chifukwa cha kukana kwake moto, kukana dzimbiri komanso kukhazikika kwa kufalitsa. Chifukwa cha kusintha kosalekeza kwa zofunikira pachitetezo cha moto komanso chitukuko chachangu cha mapulojekiti a mphamvu zongowonjezwdwa, msika wa zingwe zoteteza ku moto zomwe zili ndi mchere ndi waukulu. Komabe, mtengo wake wokwera komanso zofunikira pakukhazikitsa ziyeneranso kuganiziridwa posankha ndikugwiritsa ntchito. Pakukonza mtsogolo, zingwe zoteteza ku moto zomwe zili ndi mchere zipitiliza kuchita zabwino zake zapadera pakufalitsa mphamvu ndi chitetezo cha moto m'mbali zonse za moyo.
