Umboneleli weHlabathi woKhuseleko lweNdalo

Itekhnoloji entsha ethambileyo ethe tye kunye nokusetyenziswa kwayo kwizinto zokukhusela ubushushu

Ukususela ngo-1966, i-EM Technology ibizinikele kuphando nophuhliso lwezixhobo zokukhusela ubushushu. Kwiminyaka engama-56 yokulima kushishino, kuye kwasekwa inkqubo enkulu yophando lwesayensi, kuye kwaphuhliswa iintlobo ezingaphezu kwama-30 zezinto zokukhusela ubushushu ezintsha, ezisebenza ngombane, oomatshini, ipetroli, iikhemikhali, izixhobo ze-elektroniki, iimoto, ulwakhiwo, amandla amatsha kunye namanye amashishini. Phakathi kwazo, ukusetyenziswaIzinto zokukhusela ubushushu kwiimashini zokubumba nazo zezinye zeendlela eziphambili esigxile kuzo.

Njengesizukulwana esitsha setekhnoloji yokudlulisa i-DC, uthumelo lwe-DC oluguquguqukayo lufana nothumelo lwe-HVDC kwisakhiwo, olusakhiwa zizikhululo zokuguqula kunye nemigca yokudlulisa i-DC. Ngokwahlukileyo kuthumelo lwe-HVDC lohlobo lwangoku loguqulelo olusekelwe kwitekhnoloji yokutshintsha elawulwa yisigaba, i-converter kwi-transmission ye-DC eguquguqukayo yi-voltage source converter (VSC), ebonakaliswa kukusetyenziswa kwezixhobo ezitshintshayo (ngesiqhelo i-IGBT) kunye netekhnoloji yokuguqula i-frequency ephezulu. Kwiminyaka yakutshanje, uthumelo lwe-DC oluguquguqukayo luphuhlisa ukuya kwinqanaba eliphezulu le-voltage kunye nomthamo.

Imeko yesicelo se-IGBT: I-IGBT igcwele ityhubhu ye-bipolar yesango eligqunyiweyo, enokucinywa, ineenzuzo zokulahleka okuncinci kunye nolawulo olulula, kwaye inokujongwa njenge-CPU yokudluliselwa okuthe tye ngqo. Okwangoku, i-IGBT esetyenziswa kule projekthi zonke ziimveliso ezingenisiweyo, ikakhulu i-ABB kunye ne-Siemens, ngelixa i-IGBT yasekhaya ene-voltage ephezulu kunye nomthamo ophezulu ayinazo iimveliso ezivuthiweyo. Okwangoku, inkqubela phambili yendawo ihamba kancinci, ukuxhomekeka kokungenisa kunamandla, kwaye umngcipheko mkhulu kakhulu. Kwangaxeshanye, iindleko ze-IGBT zimalunga ne-30% yeendleko zevalvu.

Ukuba nokwenzeka kwe-IGCT entsha: Ngenxa yokuba i-IGBT inokwenzeka kancinci eTshayina, sizama ukutshintsha i-IGBT nge-IGCT. Ukutshintsha rhoqo, amandla okuqhuba kunye nokunye ukusebenza kwe-IGCT yendabuko kungaphantsi kwe-IGBT, kodwa ineenzuzo ezithile kumthamo, ilahleko yemeko, ilahleko yokutshintsha kunye neendleko (ixabiso leemveliso ezinomthamo ofanayo limalunga ne-1/2 ye-IGBT). Nangona kunjalo, ukuba i-IGCT yendabuko isetyenziswa kwi-UHV flexible power transmission, xa i-IGCT ivuliwe, i-diode iya kuvelisa i-reverse recovery current enkulu, eya kuba nefuthe elikhulu kwinkqubo. Ke ngoko, ukuze sikhusele i-diode, siphande i-ICCT entsha ngokongeza iisekethe ezongezelelweyo zokufunxa kwimodyuli ye-IGCT yendabuko ukunciphisa ifuthe kwinkqubo.

Izicelo Ezintsha ze-IGCT: Ngokongezwa kweesekethe ezongezelelweyo zokufunxa, uyilo lwethu olutsha lwe-IGCT luncinci ngakumbi kwaye lunokumelana okuphezulu kwempembelelo kunye nokuthembeka okuphezulu, ngoko ke singakwazi ukuvelisa izixhobo zokufunxa ezinokuthembeka okuphezulu kokufunxa kunye namandla oomatshini. I-Xd Power System Co., Ltd. iphanda kwangaphambili ngezinto zokufunxa zesekethe yokufunxa ye-IGCT kwiprojekthi 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 lilonke lezinto zokufunxa liya kuba liphindwe ka-2-3 kunele-IGBT.
