Umhlinzeki Womhlaba Wonke Wokuvikelwa Kwemvelo

Ubuchwepheshe obusha obuthambile obuqondile kanye nokusebenza kwabo kumpahla yokufaka

Kusukela ngo-1966, i-EM Technology izibophezele ocwaningweni nasekuthuthukisweni kwezinto zokufakelwa. Kutshalwa iminyaka engama-56 embonini, kwakhiwa uhlelo olukhulu locwaningo lwesayensi, kuye kwasungulwa izinhlobo ezingaphezu kuka-30 zezinto ezintsha zokufakelwa, ezisetshenziswa amandla kagesi, imishini, uphethiloli, amakhemikhali, izinto zikagesi, izimoto, ezokwakha, amandla amasha nezinye izimboni. . Phakathi kwabo, isicelowe-insulation material emishinini yokubumba futhi ingenye yezinkomba ezibalulekile esigxile kuzo.

Njengesizukulwane esisha sobuchwepheshe bokudlulisa i-DC, ukudluliswa kwe-DC okuguquguqukayo kufana nokudluliswa kwe-HVDC esakhiweni, esakhiwe iziteshi zokuguqula kanye nemigqa yokudlulisa ye-DC. Ihlukile ohlotsheni lwamanje lwe-HVDC lokuguquguqula okusekelwe kubuchwepheshe bokushintsha okulawulwa yisigaba, isiguquli ku-flexible DC transmission i-voltage source converter (VSC), ebonakala ngokusetshenziswa kwamadivayisi ashintshwayo (imvamisa i-IGBT) kanye nobuchwepheshe bokumodulation obumazwana aphezulu. . Eminyakeni yamuva nje, ukudluliswa kwe-DC okuguquguqukayo kuyathuthuka kufinyelele ebangeni eliphezulu lamandla kagesi namandla.

Isimo sohlelo lokusebenza lwe-IGBT: I-IGBT igcwele ishubhu yesango eline-bipolar evalekile, engacishwa, inezinzuzo zokulahlekelwa okuncane nokulawula okulula, futhi ingabhekwa njenge-CPU yokudlulisa okuqondile okuthambile. Njengamanje, i-IGBT esetshenziswe kuphrojekthi yonke imikhiqizo evela kwamanye amazwe, ikakhulukazi i-ABB ne-Siemens, kuyilapho i-IGBT yasekhaya enamandla kagesi namandla aphezulu ayinayo imikhiqizo evuthiwe. Njengamanje, inqubekelaphambili yokwenziwa kwendawo ihamba kancane, ukuncika kwamanye amazwe kunamandla, futhi ubungozi bukhulu ngokuqhathaniswa. Ngesikhathi esifanayo, izindleko ze-IGBT zibalelwa cishe ku-30% wezindleko ze-valve.

Ukuba nokwenzeka kwe-IGCT entsha: Ngokubona ukuba nokwenzeka okuphansi kwe-IGBT e-China, sizama ukufaka i-IGCT esikhundleni se-IGBT. Imvamisa yokushintsha, amandla okushayela nokunye ukusebenza kwe-IGCT yendabuko kungaphansi kwe-IGBT, kodwa inezinzuzo ezithile ngomthamo, ukulahleka kwezwe, ukulahlekelwa ukushintsha kanye nezindleko (intengo yemikhiqizo enomthamo ofanayo cishe i-1/2 ye-IGBT. ). Kodwa-ke, uma i-IGCT yendabuko isetshenziswa ekudluliselweni kwamandla aguquguqukayo e-UHV, uma i-IGCT isivuliwe, i-diode izokhiqiza imanje enkulu yokuhlehla yokutakula, ezoba nomthelela omkhulu ohlelweni. Ngakho-ke, ukuze kuvikelwe i-diode, siphenye i-ICCT entsha ngokungeza ama-circuit absorption eyengeziwe kumojula ye-IGCT yendabuko ukuze sinciphise umthelela ohlelweni.

Izicelo Ezintsha ze-IGCT: Ngokungezwa kwamasekhethi angeziwe okumuncwa, idizayini yethu entsha ye-IGCT ihlangene kakhudlwana futhi inokumelana nomthelela ophezulu kanye nokuthembeka okuphezulu, ukuze sikwazi ukwenza izinto zokufaka izinto ezinokwethenjelwa okuphezulu kokufakwa kanye namandla emishini. I-Xd Power System Co., Ltd. icwaninga kusengaphambili izinto zokufakelwa zesekhethi yokumunca ye-IGCT yephrojekthi ye-Yunnan Maitrei. Uma umklamo usekelwe kusikimu sesistimu Yamandla e-XD, inani lamamojula e-IGCT lizoncishiswa cishe ngo-3% uma liqhathaniswa ne-IGBT, futhi inani eliphelele lezinto zokufakelwa lizoba izikhathi ezingu-2-3 kune-IGBT.
