Umnikezeli wehlabathi woKhuseleko lweNdalo

Itekhnoloji entsha ethambileyo ethe ngqo kunye nokusetyenziswa kwayo kwizinto zokugquma

Ukusukela ngo-1966, i-EM Technology izibophelele kuphando nophuhliso lwemathiriyeli yokugquma. Iminyaka engama-56 yokulima kushishino, inkqubo enkulu yophando lwezenzululwazi yenziwe, ngaphezu kwe-30 iintlobo zezinto ezintsha zokugquma ziye zaphuhliswa, zisebenzisa amandla ombane, oomatshini, i-petroleum, iikhemikhali, i-elektroniki, iimoto, ulwakhiwo, amandla amatsha kunye namanye amashishini. . Phakathi kwabo, isiceloizinto zokugquma koomatshini bokubumba ikwayenye yeendlela eziphambili esigxile kuzo.

Njengesizukulwana esitsha sobuchwephesha bothumelo lwe-DC, ukuhanjiswa kwe-DC okuguquguqukayo kuyafana nokuhanjiswa kwe-HVDC kwisakhiwo, esaqulunqwa kwizikhululo zokuguqula kunye neentambo zothumelo zeDC. Ngokwahlukileyo kumthombo wangoku wokuguqula uhlobo lokuhanjiswa kwe-HVDC ngokusekwe kwitekhnoloji yothungelwano olulawulwa sisigaba, umguquleli kwi-flexible DC transmission yi-voltage source converter (VSC), ebonakala ngokusetyenziswa kwezixhobo ezitshintshayo (ngokuqhelekileyo IGBT) kunye neteknoloji yokumodareyitha i-high-frequency modulation. . Kwiminyaka yakutshanje, ukuhanjiswa kwe-DC okuguquguqukayo kukhula ukuya kwinqanaba eliphezulu lombane kunye nomthamo.

Ubume besicelo se-IGBT: I-IGBT igcwele i-tube ye-bipolar ye-insulated esangweni, enokucima, ineenzuzo zokulahlekelwa okuncinci kunye nokulawula okulula, kwaye inokuthathwa njenge-CPU yokuhanjiswa ngokuthe ngqo. Okwangoku, i-IGBT esetyenziswayo kule projekthi zizo zonke iimveliso ezithunyelwa kwamanye amazwe, ikakhulu i-ABB kunye ne-Siemens, ngelixa i-IGBT yasekhaya ene-voltage ephezulu kunye nomthamo ophezulu ayinayo imveliso evuthiweyo. Okwangoku, inkqubela phambili yokwenziwa kwasekhaya iyacotha, ukuxhomekeka kwempahla kwamanye amazwe kunamandla, kwaye umngcipheko mkhulu. Ngexesha elifanayo, ixabiso le-IGBT libalelwa malunga ne-30% yexabiso le-valve.

Ukuba nokwenzeka kwe-IGCT entsha: Ngokujonga ukuba nokwenzeka okuphantsi kwe-IGBT e-China, sizama ukutshintsha i-IGBT nge-IGCT. I-frequency switching, amandla okuqhuba kunye nokunye ukusebenza kwe-IGCT yendabuko ingaphantsi kwe-IGBT, kodwa ineenzuzo ezithile kwisikhundla, ilahleko yelizwe, ilahleko yokutshintsha kunye neendleko (ixabiso leemveliso ezinomthamo ofanayo malunga ne-1/2 ye-IGBT. ). Nangona kunjalo, ukuba i-IGCT yendabuko isetyenziselwa ukuhanjiswa kwamandla okuguquguqukayo kwe-UHV, emva kokuba i-IGCT ivuliwe, i-diode iya kuvelisa i-reverse recovery current enkulu, eya kuba nefuthe elikhulu kwinkqubo. Ngoko ke, ukwenzela ukukhusela i-diode, siye saphanda i-ICCT entsha ngokongeza iisekethe ezongezelelweyo ze-absorption kwimodyuli ye-IGCT yendabuko ukunciphisa impembelelo kwinkqubo.

Izicelo ezitsha ze-IGCT: Ngokudityaniswa kweesekethe zokufunxa ezongezelelweyo, uyilo lwethu olutsha lwe-IGCT luxinene ngakumbi kwaye lunokumelana neempembelelo eziphezulu kunye nokuthembeka okuphezulu, ukuze sikwazi ukwenza imathiriyeli yokugquma ngokuthembeka okuphezulu kunye namandla omatshini. I-Xd Power System Co., Ltd. iphanda kwangaphambili izixhobo zokufakelwa kwe-IGCT yokufunxa isekethe yeprojekthi yeYunnan Maitrei. Ukuba uyilo lusekelwe kwiskimu senkqubo ye-XD Power, inani leemodyuli ze-IGCT liya kuncitshiswa malunga ne-3% xa kuthelekiswa ne-IGBT, kwaye inani elipheleleyo lezinto zokugquma liya kuba ngamaxesha angama-2-3 e-IGBT.
