Chingwe Chotetezedwa ndi Mineral (MI Cable) ndi chingwe cholimba kwambiri chomwe sichimayaka moto chomwe chimachokera ku dongosolo la zingwe zopanda organic. Mosiyana ndi zingwe zachikhalidwe zomwe zimadalira zinthu zoteteza polima monga PVC,XLPEndiLSZHChingwe cha MI chimapangidwa pogwiritsa ntchito conductor yamkuwa, chigoba chamkuwa chopanda msoko, ndi zinthu zoteteza za magnesium oxide (MgO) ngati maziko ake. Dongosolo lazinthuli limatsimikizira magwiridwe antchito ake okhazikika pansi pa kutentha kwambiri komanso moto.
Poganizira za chitukuko cha zipangizo za chingwe, makina a zinthu zopanda chilengedwe amathetsa mavuto a kuwonongeka, kusungunuka, ndi kutulutsa utsi woopsa omwe amapezeka mu zinthu zachilengedwe kutentha kwambiri. Izi zimapangitsa kuti chingwe cha MI chikhale yankho lofunika kwambiri pa zingwe zosagwira moto, zingwe zotentha kwambiri, ndi zipangizo zamakina amphamvu kwambiri.
Kapangidwe ka Zinthu ndi Kapangidwe kake
Kugwira ntchito kwa chingwe cha MI kumadalira kwambiri makina ake ogwiritsira ntchito chingwe. Choyendetsacho chimapangidwa ndi chowongolera cha mkuwa choyera kwambiri, chomwe chimapereka mphamvu zamagetsi zabwino komanso kukana kochepa, zomwe zimapangitsa kuti chikhale gawo lofunika kwambiri la zipangizo zamagetsi.
Chitsulo choteteza kutentha chimagwiritsa ntchito magnesium oxide (MgO2), chomwe ndi chinthu choteteza kutentha chomwe chimasungunuka pamwamba pa 2800°C. Chimasunga mphamvu yokhazikika ya dielectric ngakhale kutentha kwambiri, chomwe chimagwira ntchito ngati chinthu chachikulu chomwe chimalola kuti moto usapse.
Gawo lakunja lili ndi chigoba cha mkuwa chopanda msoko, chomwe chimapereka chitetezo cha makina komanso kukana dzimbiri. Chimaperekanso mphamvu yabwino kwambiri yoyendetsera kutentha komanso kuteteza magetsi (EMI shielding). Kuphatikiza apo, chigoba cha mkuwa chimagwira ntchito ngati chowongolera nthaka, kupangitsa kuti kapangidwe ka makinawo kakhale kosavuta komanso kulimbitsa kudalirika kwa ntchito.
Ubwino wa Moto ndi Zinthu Zake
Pakakhala moto, kusiyana kwa zinthu kumakhala kofunikira kwambiri. Zipangizo zachikhalidwe za polymeric cable nthawi zambiri zimayamba kuwola kapena kulephera kutentha kutentha pakati pa 300°C ndi 500°C, zomwe zimatulutsa utsi ndi mpweya woopsa.
Mosiyana ndi zimenezi, chingwe cha MI chimachokera ku makina osanjikiza zinthu zachilengedwe, ndipo chimatha kusunga mphamvu zamagetsi ngakhale chikayaka moto pa kutentha kwa pafupifupi 950°C. Chimatha kugwira ntchito mosalekeza kwa mphindi zoposa 90, kukwaniritsa miyezo yapadziko lonse yolimbana ndi moto monga BS 6387 ndi IEC 60331.
Pakadali pano, zingwe zake zosayaka sizimayaka, sizimatulutsa utsi, komanso sizimatulutsa mpweya woipa, zomwe zimapangitsa kuti chingwe cha MI chikhale njira yabwino kwambiri yogwiritsira ntchito zingwe zotetezera moto zomwe zimagwiritsidwa ntchito kwambiri pamagetsi adzidzidzi komanso zoteteza moto.
Ubwino ndi Mavuto Ochokera ku Zinthu Zofunika
Kuchokera pakuwona zinthu za chingwe, chingwe cha MI chimapereka kukana moto, mphamvu yonyamula mphamvu yamagetsi, komanso moyo wautali (nthawi zambiri zaka 40-60). Ndi choyenera kumalo otentha kwambiri, chinyezi, komanso oopsa.
Komabe, chifukwa cha kugwiritsidwa ntchito kwambiri kwa zinthu zamkuwa ndi magnesium oxide insulation (MgO insulation), mtengo wonse wa zinthuzo ndi wokwera kuposa wa makina achizolowezi a chingwe. Kuphatikiza apo, kapangidwe kake konse ka zinthu zopanda organic kamapangitsa kuti zikhale zolimba kwambiri, zomwe zimapangitsa kuti pakhale zofunikira kwambiri pakukhazikitsa chingwe, kupindika bwino, komanso kutseka kwa zingwe.
Mapangidwe a chingwe cha MI chosinthasintha amatha kusintha magwiridwe antchito a kukhazikitsa, komanso amawonjezera zovuta za zinthu ndi kupanga.
Mapulogalamu Odziwika
Chifukwa cha ntchito yake yabwino kwambiri yoteteza zingwe ku moto, chingwe cha MI chimagwiritsidwa ntchito kwambiri m'makonzedwe oteteza moto m'nyumba zazitali, zomangamanga zoyendera sitima, malo akuluakulu aboma, komanso malo okhala ndi mafuta ambiri komanso zoopsa zoyaka moto.
Mu ntchito izi, magwiridwe antchito okhazikika a makina ake a chingwe amatsimikizira kuti magetsi akupitilizabe kugwiritsidwa ntchito ngakhale pakakhala moto kapena zinthu zoopsa kwambiri, zomwe zimapangitsa kuti ikhale yankho lofunikira kwambiri pamakina ofunikira amagetsi.
Kutsiliza: Zochitika pa Kupanga Zipangizo Zazingwe
Kuchokera pakuwona momwe zinthu zikuyendera pakukula kwa zipangizo za chingwe, chingwe cha MI chikuyimira kusintha kwakukulu kuchokera ku zinthu zoteteza zachilengedwe kupita ku zinthu zoteteza zachilengedwe.
Kwa ogulitsa zinthu za chingwe, kuthekera kolamulira kuyera, kufalikira kwa tinthu tating'onoting'ono, kukana chinyezi, ndi mphamvu ya magnesium oxide (MgO insulation), komanso kupezeka kosatha kwa zinthu za conductor zamkuwa ndi m'chikhatho cha mkuwa, zidzakhala zinthu zofunika kwambiri pamsika wazinthu za chingwe zotetezeka ku moto.
Tikupitiriza kuyang'ana kwambiri ndikupereka mayankho okhudzana ndi zipangizo za chingwe, kuthandiza makasitomala kugwiritsa ntchito chingwe cha MI ndi makina ena a chingwe cholimba omwe sagwira ntchito kwambiri.
