Umhlinzeki Womhlaba Wonke Wokuvikelwa Kwemvelo

Ubuchwepheshe obusha obuthambile obuqondile kanye nokusetshenziswa kwabo ezintweni zokufaka umswakama

Kusukela ngo-1966, i-EM Technology ibilokhu izibophezele ocwaningweni nasekuthuthukisweni kwezinto zokuvikela ukushisa. Sekuphele iminyaka engama-56 itshalwa embonini, kwakhiwe uhlelo olukhulu locwaningo lwesayensi, kwakhiwe izinhlobo ezingaphezu kuka-30 zezinto zokuvikela ukushisa ezintsha, ezikhonza amandla kagesi, imishini, uphethiloli, amakhemikhali, ama-elekthronikhi, izimoto, ukwakhiwa, amandla amasha kanye neminye imboni. Phakathi kwazo, ukusetshenziswaIzinto zokuvikela ukushisa emishinini yokubumba nazo zingenye yezindlela ezibalulekile esigxile kuzo.

Njengesizukulwane esisha sobuchwepheshe bokudlulisa i-DC, ukudluliselwa kwe-DC okuguquguqukayo kufana nokudluliselwa kwe-HVDC ngesakhiwo, okusakhiwa iziteshi zokuguqula kanye nemigqa yokudlulisa i-DC. Ngokungafani nokudluliselwa kwe-HVDC yohlobo lwamanje lokuguqula umthombo ngokusekelwe kubuchwepheshe bokushintsha okulawulwa yisigaba, i-converter ekudlulisweni kwe-DC okuguquguqukayo i-voltage source converter (VSC), ebonakala ngokusetshenziswa kwamadivayisi ashintshayo (ngokuvamile i-IGBT) kanye nobuchwepheshe bokuguqula imvamisa ephezulu. Eminyakeni yamuva nje, ukudluliselwa kwe-DC okuguquguqukayo kuthuthuka kuya ezingeni eliphezulu le-voltage kanye nomthamo.

Isimo sokusebenza se-IGBT: I-IGBT igcwele ishubhu ye-bipolar yesango elivikelwe, elingacinywa, linezinzuzo zokulahlekelwa okuncane kanye nokulawula okulula, futhi lingabhekwa njenge-CPU yokudlulisela okuqondile okuthambile. Njengamanje, i-IGBT esetshenziswa kulo msebenzi yonke imikhiqizo engenisiwe, ikakhulukazi i-ABB ne-Siemens, kuyilapho i-IGBT yasekhaya ene-voltage ephezulu kanye nomthamo ophezulu ingenayo imikhiqizo evuthiwe. Njengamanje, inqubekela phambili yendawo ihamba kancane, ukuncika kokungenisa kunamandla, futhi ingozi inkulu kakhulu. Ngesikhathi esifanayo, izindleko ze-IGBT zibiza cishe u-30% wezindleko zevalvu.

Ukungenzeka kwe-IGCT entsha: Ngenxa yokuthi i-IGBT iyasebenza kancane eShayina, sizama ukufaka i-IGBT esikhundleni sayo nge-IGCT. Imvamisa yokushintsha, amandla okushayela kanye nokunye ukusebenza kwe-IGCT yendabuko kungaphansi kwe-IGBT, kodwa kunezinzuzo ezithile ngomthamo, ukulahlekelwa kwesimo, ukulahlekelwa kokushintsha kanye nezindleko (intengo yemikhiqizo enamandla afanayo cishe i-1/2 ye-IGBT). Kodwa-ke, uma i-IGCT yendabuko isetshenziswa ekudlulisweni kwamandla okuguquguqukayo kwe-UHV, uma i-IGCT isivuliwe, i-diode izokhiqiza ugesi omkhulu wokubuyisela emuva, ozoba nomthelela omkhulu ohlelweni. Ngakho-ke, ukuze sivikele i-diode, sihlole i-ICCT entsha ngokungeza amasekethe engeziwe okumunca kumojuli ye-IGCT yendabuko ukuze sinciphise umthelela ohlelweni.

Izinhlelo Ezintsha ze-IGCT: Ngokwengeza amasekethe okufaka amanzi engeziwe, umklamo wethu omusha we-IGCT uncane kakhulu futhi unokumelana okuphezulu komthelela kanye nokuthembeka okuphezulu, ngakho-ke singakwazi ukukhiqiza izinto zokufaka amanzi ezinokwethenjelwa okuphezulu kokufaka amanzi kanye namandla omshini. I-Xd Power System Co., Ltd. icwaninga kusengaphambili ngezinto zokufaka amanzi zesekethe yokufaka amanzi ye-IGCT yephrojekthi ye-Yunnan Maitrei. Uma umklamo usekelwe ohlelweni lwesistimu ye-XD Power, inani lamamojula e-IGCT lizoncishiswa cishe ngo-3% uma kuqhathaniswa ne-IGBT, futhi inani eliphelele lezinto zokufaka amanzi lizoba ngokuphindwe kabili-kathathu kunele-IGBT.
