Ntiaj Teb Tsum Ntawm Kev Tiv Thaiv Ib Puag Ncig

Tus tshiab mos mos ncaj ncees thiab nws cov ntawv thov hauv cov khoom siv rwb thaiv tsev

Txij li xyoo 1966, em thev naus laus zis tau cog lus rau kev tshawb fawb thiab kev txhim kho cov ntaub ntawv rwb thaiv tsev. 56 xyoo kev cog qoob loo hauv kev lag luam, ntau dua 30 hom hluav taws xob rwb thaiv tsev tau raug tsim, kho cov khoom siv hluav taws xob, kev tsim kho, kev lag luam tshiab thiab lwm yam kev lag luam Cov. Ntawm lawv, daim ntawv thovntawm rwb thaiv tsev cov khoom hauv moulding machine kuj yog ib qho ntawm cov lus tseem ceeb uas peb tau tsom rau.

Raws li ib tiam tshiab ntawm DC kis thev naus laus zis, hloov tau DC kis zoo ib yam li HVDC kis hauv cov qauv thiab DC kis kab. Txawv los ntawm kev hloov pauv tam sim no huvc kis rau theem hloov pauv (VSC), feem ntau igbt) thiab high-zaus kev siv thev naus laus zis Cov. Nyob rau hauv xyoo tsis ntev los no, hloov tau DC kis tau los txhim kho rau cov qib siab dua thiab muaj peev xwm.

Daim ntawv thov cov xwm txheej ntawm igbt: igbt yog tag nrho ntawm insulated Gate Bipolar Tube, muaj qhov kev tswj hwm yooj yim, thiab tuaj yeem raug suav tias yog CPU ntawm kev sib kis ncaj qha. Ntawm tam sim no, igb thov rau txoj haujlwm yog txhua cov khoom lag luam txawv teb, feem ntau abb thiab siemens, thaum muaj peev xwm muaj peev xwm tsis muaj cov khoom muaj peev xwm. Tam sim no, txoj kev nce hauv zos yog qeeb, ntshuam cov chaw nyob yog muaj zog, thiab kev pheej hmoo yog loj. Nyob rau tib lub sijhawm, tus nqi ntawm igBB cov account rau li 30% ntawm tus nqi valve.

Ua tau ntawm New IGCT: Hauv kev pom ntawm cov tsis muaj nuj nqis ntawm igbt hauv Suav teb, peb sim hloov igbt nrog igct. Lub zog hloov chaw, tsav tsheb fais fab thiab lwm qhov kev ua tau zoo ntawm cov tsoos ib txwm muaj, ntawm cov khoom lag luam, tab sis nws muaj qhov peev xwm ntawm tib yam yog li 1/2 ntawm igbt ). Txawm li cas los xij, yog tias cov tsoos IGCT yog thov rau UHV hloov tau lub zog kis, ib zaug Diode yuav tsim kom muaj kev rov qab zoo dua tam sim no, uas yuav muaj kev cuam tshuam zoo rau cov kab ke. Yog li ntawd, txhawm rau tiv thaiv cov diode, peb tshawb xyuas cov ICCT tshiab los ntawm kev ntxiv kev nqus cov kab ke ntxiv rau cov kev cuam tshuam ntawm cov kab ke.

Daim ntawv thov IGC tshiab: nrog ntxiv ntawm ntxiv kev nqus cov khoom siv lossis muaj peev xwm siab dua thiab ua cov rwb thaiv tsev ntau dua thiab lub zog kho tshuab. XD Hwj Chim System Co., Ltd. Tshawb nrhiav cov ntaub ntawv rwb thaiv tsev rau kev nqus cov Circuit Txwv rau Yunnan Maitri Project. Yog tias tus qauv tsim raws XD cov phiaj xwm hluav taws xob XD lub zog yuav raug txo los ntawm kwv yees li ntawm 3% piv nrog 2-3 zaug uas yog igbt.
