Ib tug tshiab mos ncaj tshuab thiab nws daim ntawv thov nyob rau hauv lub rwb thaiv tsev cov ntaub ntawv

Txij li xyoo 1966, EM Technology tau cog lus rau kev tshawb fawb thiab kev tsim cov ntaub ntawv rwb thaiv tsev. 56 xyoo kev cog qoob loo hauv kev lag luam, kev tshawb fawb loj loj tau tsim, ntau dua 30 hom tshiab rwb thaiv tsev cov ntaub ntawv tau tsim, pab lub zog hluav taws xob, tshuab, roj av, tshuaj, hluav taws xob, tsheb, kev tsim kho, lub zog tshiab thiab lwm yam lag luam. . Ntawm lawv, daim ntawv thovntawm cov khoom siv rwb thaiv tsev hauv cov tshuab molding kuj yog ib qho ntawm cov lus qhia tseem ceeb uas peb tau tsom mus rau.

Raws li lub cim tshiab ntawm DC kis tau tus mob thev naus laus zis, hloov pauv DC kis tau tus mob zoo ib yam li HVDC kis tau tus mob hauv cov qauv, uas tseem muaj cov chaw hloov pauv thiab DC cov kab sib kis. Qhov sib txawv ntawm qhov tam sim no converter hom HVDC kis tau tus mob raws li theem-tswj commutation technology, lub converter nyob rau hauv saj zawg zog DC kis tau tus mob yog voltage qhov converter (VSC), uas yog yus muaj los ntawm kev siv ntawm switchable li (feem ntau IGBT) thiab high-frequency modulation technology. . Nyob rau hauv xyoo tas los no, hloov tau DC kis tau tus mob mus rau qib siab dua voltage thiab muaj peev xwm.

Daim ntawv thov txheej txheem ntawm IGBT: IGBT yog tag nrho ntawm lub qhov rooj ntawm lub qhov rooj bipolar, uas tuaj yeem muab tua, muaj qhov zoo ntawm kev poob me me thiab kev tswj tau yooj yim, thiab tuaj yeem suav tau tias yog CPU ntawm kev sib kis ncaj qha. Tam sim no, IGBT thov rau qhov project yog tag nrho cov khoom tuaj txawv teb chaws, feem ntau ABB thiab Siemens, thaum IGBT domestic nrog high voltage thiab siab muaj peev xwm tsis muaj cov khoom lag luam. Tam sim no, localization kev vam meej yog qeeb, ntshuam dependence muaj zog, thiab cov kev pheej hmoo yog loj heev. Nyob rau tib lub sijhawm, tus nqi ntawm IGBT suav txog li 30% ntawm tus nqi valve.

Kev ua tau zoo ntawm IGCT tshiab: Raws li qhov ua tau zoo ntawm IGBT hauv Suav teb, peb sim hloov IGBT nrog IGCT. Hloov zaus, tsav lub zog thiab lwm yam kev ua tau zoo ntawm IGCT ib txwm muaj qis dua rau IGBT, tab sis nws muaj qee qhov zoo ntawm lub peev xwm, kev poob hauv xeev, hloov pauv thiab tus nqi (tus nqi ntawm cov khoom uas muaj peev xwm tib yam li 1/2 ntawm IGBT. ). Txawm li cas los xij, yog tias IGCT ib txwm siv rau UHV hloov pauv lub zog xa mus, thaum lub IGCT tau qhib, lub diode yuav tsim qhov rov qab loj dua tam sim no, uas yuav muaj kev cuam tshuam zoo rau lub cev. Yog li ntawd, txhawm rau tiv thaiv lub diode, peb tau tshawb xyuas ICCT tshiab los ntawm kev ntxiv cov khoom nqus nqus ntxiv ntawm cov qauv IGCT ib txwm siv los txo qhov cuam tshuam rau lub cev.

Daim Ntawv Thov IGCT tshiab: Nrog rau qhov sib ntxiv ntawm cov khoom siv ntxiv, peb cov qauv IGCT tshiab yog qhov sib zog dua thiab muaj kev cuam tshuam ntau dua thiab muaj kev ntseeg siab, yog li peb tuaj yeem tsim cov ntaub ntawv rwb thaiv tsev nrog cov rwb thaiv tsev siab dua thiab lub zog txhua yam. Xd Power System Co., Ltd. yog ua ntej tshawb fawb cov ntaub ntawv rwb thaiv tsev rau IGCT nqus Circuit Court rau Yunnan Maitrei project. Yog tias tus qauv tsim raws li XD Lub Hwj Chim Txheej Txheem Txheej Txheem, tus naj npawb ntawm IGCT modules yuav raug txo los ntawm 3% piv nrog IGBT, thiab tag nrho cov khoom siv rwb thaiv tsev yuav yog 2-3 npaug ntawm IGBT.
