Padziko Lonse Lapansi Chitetezo cha chilengedwe

Tekinolojeni yatsopano yofewa komanso ntchito yake mu zotchinga

Kuyambira 1966, ukadaulo wa EM womwe wadzipereka kuti ufufuze ndi kukula kwa zinthu zokongoletsera. Kulimidwa kwa zaka 56 Mwa iwo, kugwiritsa ntchitoMakina otchinga pamakina owumba ndi amodzi mwa malangizo ofunikira omwe timayang'ana.

Monga m'badwo watsopano wamatekinoloje, kufalikira kwa DC kumafanana ndi kufala kwa HVDC kumapangidwe, komwe kumakhalabe kwa otembenuka ndi mizere ya DC. Zosiyana ndi zomwe zikuchitika pakalipano M'zaka zaposachedwa, kufalikira kwa DC kumayamba kulowera kudera lamagetsi kwambiri komanso kuthekera.

Mkhalidwe wa IGBT: IGBT yadzaza pachipata cha Bipolar, chomwe chitha kuyimitsidwa, chimakhala ndi maubwino otayika komanso kuwongolera mosavuta, ndipo amatha kuwonedwa ngati njira yochepetsetsa mwachindunji. Pakadali pano, igbt yomwe imagwiritsidwa ntchito ku polojekitiyi ndi katundu onse omwe amatenga nawo mbali, makamaka abb ndi kuthyani, pomwe apanyumba oigt ndi magetsi apamwamba komanso kuchuluka kwa zinthu zokhwima. Pakadali pano, kupita patsogolo kwakokha kuli pang'onopang'ono, kudalirika kumalimba, ndipo chiopsezo ndi chachikulu. Nthawi yomweyo, mtengo wa maakaunti a iGBT pafupifupi 30% ya valavu.

Kuthekera kwa igct yatsopano: powona kuthekera kotsika kwa IGBT ku China, timayesetsa kusinthanso igbt ndi igect. Kusintha kwapadera, kuyendetsa mphamvu ndi magwiridwe ena achikhalidwe ndi otsika kwambiri ku iGBT, koma ili ndi maubwino enanso omwe ali ndi vuto lililonse, kuwonongeka kwa zinthu zomwezo. Komabe, ngati mwambowo umagwiritsidwa ntchito potumiza mphamvu kwamphamvu, kamodzi pa iGect watembenuka, DIDOD imatulutsa kuchira kwakukulu komwe kumachitika, zomwe zingakhudze kwambiri dongosolo. Chifukwa chake, pofuna kuteteza diide, titafufuza ku ICCT yatsopano powonjezera ma bloadgy owonjezera pa gawo lachikhalidwe kuti muchepetse dongosolo.

Ntchito zatsopano: Ndi kuwonjezera mabwalo oyamwa, kapangidwe kathu kakang'ono kamene kamakhala kovuta komanso kudalirika kwakukulu, motero titha kupanga zida zotchinga ndi kudalirika kwakukulu. Maulamuliro a XD Power System Co., Ltd. Akufufuza kafukufuku wazosasinthika kwa madera a igtction a Yunnan Maitrei polojekije. Ngati kapangidwe ka XD Postter Systemme, kuchuluka kwa ma module a iGT adzachepetsedwa ndi 3% poyerekeza ndi igbt, ndipo kuchuluka kwa zinthu zotumbuzi zikhala katatu za IGBT.
