Mu gawo la Magalimoto Atsopano Ogwiritsa Ntchito Mphamvu (EV, PHEV, HEV), kusankha zipangizo za zingwe zamagetsi amphamvu ndikofunikira kwambiri pa chitetezo cha galimoto, kulimba, komanso magwiridwe antchito ake. Polyethylene yolumikizidwa (XLPE) ndi rabara ya silicone ndi ziwiri mwa zipangizo zodziwika bwino zotetezera kutentha, koma zimasiyana kwambiri pakugwira ntchito kwa kutentha kwambiri, mphamvu zotetezera kutentha, mphamvu ya makina, ndi zina zambiri.
Zonse pamodzi, zonse ziwiriXLPEndi rabara ya silicone zimagwiritsidwa ntchito kwambiri mu zingwe zamkati mwa magalimoto. Ndiye, ndi chipangizo chiti chomwe chingakhale choyenera kwambiri pa zingwe zamagetsi amphamvu kwambiri m'magalimoto atsopano amphamvu?
N’chifukwa Chiyani Zingwe Zamagetsi Zapamwamba Za Magalimoto Atsopano Amphamvu Zimafuna Zipangizo Zotetezera Mphamvu Zapamwamba?
Zingwe zamagetsi zamagetsi zambiri m'magalimoto atsopano amphamvu zimagwiritsidwa ntchito makamaka pa batire, mota, makina owongolera zamagetsi, ndi makina ochajira, ndi ma voltage ogwiritsira ntchito kuyambira 600V mpaka 1500V, kapena kupitirira apo.
Izi zimafuna kuti zingwe zikhale ndi:
1) Kuteteza bwino kwambiri kuti magetsi asawonongeke komanso kuti zinthu zisamayende bwino.
2) Kukana kutentha kwambiri kuti kupirire malo ovuta ogwirira ntchito komanso kupewa kuwonongeka kwa insulation.
3) Kukana mwamphamvu kupsinjika kwa makina, kupindika, kugwedezeka, ndi kuwonongeka.
4) Kukana dzimbiri kwa mankhwala kuti zigwirizane ndi malo ovuta ndikuwonjezera nthawi ya ntchito.
Pakadali pano, zigawo zotetezera kutentha za zingwe zamagetsi amphamvu kwambiri m'magalimoto atsopano amagwiritsa ntchito kwambiri XLPE kapena rabara ya silicone. Pansipa, tiyerekeza mwatsatanetsatane zinthu ziwirizi.
Kuchokera patebulo, zitha kuwoneka kuti XLPE imagwira ntchito bwino pankhani yolimbana ndi magetsi, mphamvu ya makina, kukana ukalamba, komanso kuwongolera ndalama, pomwe rabara ya silicone ili ndi zabwino pakukana kutentha kwambiri komanso kusinthasintha.
Nchifukwa chiyani XLPE ndi chinthu chomwe chimakondedwa kwambiri pa zingwe zamagetsi amphamvu kwambiri m'magalimoto atsopano amphamvu?
1) Kugwira Ntchito Kolimba Kwambiri Poteteza Kutenthedwa: Zipangizo zoteteza kutenthedwa za XLPE zili ndi mphamvu ya dielectric yapamwamba (≥30kV/mm), zomwe zimapangitsa kuti zikhale bwino polimbana ndi zoopsa za kuwonongeka kwa magetsi m'malo okhala ndi magetsi ambiri poyerekeza ndi rabara ya silicone. Kuphatikiza apo, zida zoteteza kutenthedwa za XLPE zili ndi kutayika kochepa kwa dielectric, zomwe zimapangitsa kuti zigwire ntchito bwino kwa nthawi yayitali, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito makina atsopano amagetsi.
2) Kapangidwe Kabwino ka Makina: Poyendetsa galimoto, kugwedezeka kuchokera m'thupi la galimoto kumatha kupangitsa kuti zingwezo zikhale zolimba kwambiri. XLPE ili ndi mphamvu yolimba kwambiri, yolimba kwambiri pakutha, komanso yolimba kwambiri, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito kwa nthawi yayitali komanso kuchepetsa ndalama zokonzera poyerekeza ndi rabara ya silicone.
3) Kukana Kukalamba Bwino: Zipangizo zotetezera kutentha za XLPE zimakhala ndi kukana bwino kukalamba kwa mitengo ya m'madzi, zomwe zimaonetsetsa kuti chingwecho chikhale chokhazikika m'malo onyowa kwambiri komanso m'malo odzaza magetsi ambiri. Izi ndizofunikira kwambiri pamagalimoto atsopano amphamvu, makamaka m'malo odzaza ndi zinthu zambiri monga mabatire amphamvu kwambiri komanso makina ochaja mwachangu.
4) Kusinthasintha Kwapakati Kuti Kukwaniritse Zofunikira pa Kulumikiza Mawaya: Poyerekeza ndi rabara ya silicone, XLPE imapereka kusinthasintha kwapakati, kusinthasintha kwa mawaya ndi mphamvu yamakina. Imagwira ntchito bwino kwambiri pazinthu monga mawaya amphamvu kwambiri m'galimoto, mizere yowongolera mota, ndi kulumikizana kwa batri.
5) Yotsika Mtengo Kwambiri: XLPE ndi yotsika mtengo kwambiri kuposa rabara ya silicone, yomwe imathandizira kupanga zinthu zambiri. Yakhala chinthu chofunikira kwambiri pakupanga zingwe zamagetsi amphamvu kwambiri m'magalimoto atsopano amphamvu.
Kusanthula kwa Zochitika Zogwiritsira Ntchito: XLPE vs Silicone Rubber
XLPE, yokhala ndi mphamvu yamagetsi yabwino kwambiri, mphamvu yamakina, komanso ubwino wake wokwera mtengo, ndi yopikisana kwambiri pakugwiritsa ntchito zingwe zamagetsi amphamvu kwambiri pamagalimoto atsopano amphamvu.
Pamene ukadaulo watsopano wamagalimoto amphamvu ukupitilira patsogolo, zida za XLPE zikukonzedwanso kuti zikwaniritse zosowa zambiri pazochitika zogwiritsira ntchito:
1) XLPE Yosatentha Kwambiri (150℃-200℃): Yoyenera makina oyendetsa magetsi a m'badwo wotsatira omwe amagwira ntchito bwino kwambiri.
2) Polyethylene Yogwirizana ndi Zero-Halogen (LSZH) Yopanda Utsi Wochepa: Imagwirizana ndi miyezo yoteteza chilengedwe ya magalimoto atsopano amphamvu.
3) Chotchingira Chokonzedwa Bwino: Chimalimbitsa kukana kusokonezedwa ndi maginito (EMI) ndikukweza kugwirizanitsa kwa maginito (EMC) kwa galimoto.
Ponseponse, XLPE ili ndi udindo waukulu mu gawo la zingwe zamagetsi zamagetsi chifukwa cha magwiridwe ake abwino kwambiri otetezera kutentha, kukana magetsi, mphamvu zamakanika, komanso ubwino wake. Ngakhale kuti rabara ya silicone ndi yoyenera malo otentha kwambiri, mtengo wake wokwera umapangitsa kuti ikhale yoyenera zosowa zapadera. Pa zingwe zamagetsi zamagetsi zamagetsi m'magalimoto atsopano, XLPE ndiye chisankho chabwino kwambiri ndipo ingagwiritsidwe ntchito kwambiri m'malo ofunikira monga ma batire, zingwe zamagalimoto zamagetsi zamagetsi zamagetsi, ndi zingwe zochapira mwachangu.
Pankhani ya chitukuko chachangu cha makampani atsopano opanga magalimoto amphamvu, makampani ayenera kuganizira zinthu monga momwe zimagwiritsidwira ntchito, zofunikira pa kukana kutentha, komanso bajeti yogulira zinthu posankha zipangizo za chingwe chamagetsi amphamvu kuti atsimikizire chitetezo ndi kulimba kwa zingwezo.
