Pakalipano, zatsopano zatenga malo apamwamba pazochitika zonse za zomangamanga za dziko langa, ndi sayansi ndi luso lodzidalira komanso kudzikweza likukhala njira yothandizira chitukuko cha dziko.Monga mwambo wofunikira wogwiritsiridwa ntchito, nsalu zimakhala ndi mawonekedwe ophatikizika amitundu yambiri komanso kuphatikizika kwamatekinoloje opitilira malire, ndipo ndizofunikira kwambiri pakupanga luso laukadaulo.

Zatsopano ndi chitukuko cha mafakitale a nsalu zikuwonekera pakubwera kwa matekinoloje atsopano, zipangizo zatsopano ndi zinthu zatsopano, komanso kuyendetsa bwino kwa zomangamanga zatsopano, zipangizo zatsopano, ndi maonekedwe atsopano, ndipo zimagwira ntchito yosasinthika pakuwongolera National innovation system ndikumanga dziko lolimba mu sayansi ndiukadaulo.zotsatira.
Ulusi wochita bwino kwambiri woimiridwa ndi ulusi wa kaboni ndi ulusi wa aramid ndi zida zawo zophatikizika, monga zida zofunika kwambiri pamakampani apamwamba kwambiri padziko lonse lapansi, zimalimbikitsa nthawi zonse masitima othamanga kwambiri ndi mayendedwe ena a njanji, magalimoto amagetsi atsopano ndi milu yolipiritsa, kutumiza kwa UHV. mizere ndi mafakitale ena omwe akubwera komanso kupita patsogolo kwaukadaulo kwatsopano komanso kukweza kwa mafakitale.

Mu Seputembala 2018, pa International Rail Transit Technology Exhibition ku Berlin, Germany, CRRC Qingdao Sifang Locomotive and Rolling Stock Co., Ltd. idatulutsa m'badwo watsopano wa subway ya carbon fiber "CETROVO", yomwe imazindikira kuti kabati ya dalaivala, thupi lagalimoto. , ndipo chipinda cha zipangizo ndi bwino kuposa zipangizo zachitsulo.Kulemera kwake kumachepetsedwa pafupifupi 30%, ndipo bogie ndi 40% yopepuka kuposa chitsulo choyambirira.Ndichitsanzo chakugwiritsa ntchito kwakukulu kwa zida za carbon fiber kompositi pamasitima apamtunda mpaka pano.

Pakadali pano, CETROVO yamaliza kuyesa kwa mzere ndikuwonetsa ntchito, ndipo idapambana kuvomereza.

Carbon Fiber Bogie

Mu Disembala 2019, pulojekiti yoyamba yapadziko lonse ya "Inner Mongolia Ximeng-Shandong" UHV yothandizira pulojekiti yokhala ndi ma conductor oyambira a carbon fiber omwe amagwiritsidwa ntchito pamzere wonsewo - chingwe chotumizira magetsi cha 1000 kV cha Datang Xilinhot Power Plant chidalumikizidwa ndi gridi ndipo chinayamba kugwira ntchito ku Inner Mongolia. .Kutalika konse ndi 14.6km, ndipo imakhazikitsidwa ndi dera limodzi.Mzerewu umatenga waya wa carbon fiber composite core wopangidwa ndi dziko langa.

Kutumizidwa kwa mzerewo sikumangopulumutsa mphamvu komanso kuchepetsa ndalama zogwiritsira ntchito, komanso kumawonjezera mphamvu yotumizira ndi 1.32 miliyoni kW • h chaka chilichonse, kuchepetsa kusowa kwa magetsi ku North China.

Chingwe chotumizira cha 1000kV cha Datang Xilinhot Power Plant

Kuphatikiza apo, ulusi wochita bwino kwambiri komanso zida zake zophatikizika zimatha kuwonekanso pamagalimoto atsopano amphamvu ndi milu yolipiritsa.Magalimoto amagetsi atsopano amagwiritsa ntchito magetsi ngati gwero lamagetsi oyendetsa, ndipo mavuto monga ma circuit short circuit kapena kuthamanga kwamphamvu kwamagetsi akuyenera kuganiziridwa.Chifukwa chake, kuwonjezera pakukana kwamagetsi otsekemera komanso kukana kwa dzimbiri, kubweza kwa moto kumafunikanso kuganiziridwa posankha zida.
Chifukwa chake, zida zophatikizika za kaboni, magalasi aatali a fiber retardant amphamvu a polypropylene, ndi zida zowonjezeredwa za PP (PPLGF35) zakhala zosankha zazikulu zanyumba za batri.
