Iyo nyowani yakapfava yakatwasuka tekinoroji uye mashandisiro ayo mune iyo insulation zvinhu

Kubva 1966, EM Tekinoroji yakazvipira kutsvagisa nekuvandudza zvinhu zvekudzivirira. 56 makore kurima muindasitiri, hombe yesainzi yekutsvagisa system yakaumbwa, anopfuura makumi matatu emhando dzezvitsva zvekudzivirira akagadzirwa, achishandira magetsi emagetsi, michina, peturu, makemikari, zvemagetsi, mota, kuvaka, simba idzva uye mamwe maindasitiri. . Pakati pavo, kushandiswayemidziyo yekudzivirira mumakina ekuumba zvakare imwe yenzira dzakakosha dzatiri kutarisa pairi.

Sechizvarwa chitsva cheDC tekinoroji yekufambisa, inochinjika DC kufambisa kwakafanana neHVDC kutapurirana muchimiro, iyo ichiri kuumbwa nezviteshi zvinoshandura uye DC mitsetse yekufambisa. Yakasiyana neyazvino sosi inoshandura mhando yeHVDC kufambisa kwakavakirwa padanho-inodzorwa commutation tekinoroji, inoshandura mune inochinjika DC transmission is voltage source converter (VSC), iyo inoratidzwa nekushandiswa kwezvinhu zvinoshanduka (kazhinji IGBT) uye yakakwirira-frequency modulation tekinoroji. . Mumakore achangopfuura, flexible DC transmission iri kusimukira yakanangana nepamusoro voltage giredhi uye kugona.

Mamiriro ekushandiswa kweIGBT: IGBT izere ne insulated gedhi bipolar chubhu, inogona kudzimwa, ine zvakanakira kurasikirwa kudiki uye kudzora kuri nyore, uye inogona kutorwa seCPU yekunyorovera yakananga kutapurirana. Parizvino, IGBT yakashandiswa kupurojekiti iyi zvese zvigadzirwa zvinotengeswa kunze kwenyika, kunyanya ABB neSiemens, nepo IGBT yemumba ine yakakwira voltage uye yakakura kwazvo isina zvigadzirwa zvakura. Parizvino, kufambira mberi kwenzvimbo kunononoka, kutsamira kwekunze kune simba, uye njodzi yakakura. Panguva imwecheteyo, mutengo weIGBT unoverengera nezve 30% yemutengo wevhavha.

Kugoneka kweiyo IGCT nyowani: Tichitarisa kushomeka kweiyo IGBT muChina, tinoedza kutsiva IGBT neIGCT. Iyo yekuchinjisa frequency, simba rekutyaira uye kumwe kuita kwechinyakare IGCT kwakaderera kune IGBT, asi ine zvimwe zvakanakira mukugona, pa-nyika kurasikirwa, kuchinja kurasikirwa uye mutengo (mutengo wezvigadzirwa zvine huwandu hwakafanana unenge 1/2 yeIGBT. ). Nekudaro, kana iyo yechinyakare IGCT ikaiswa kune UHV inochinjika kufambisa kwesimba, kana IGCT yavhurwa, diode inoburitsa yakakura reverse kudzoreredza ikozvino, iyo ichava nesimba guru pahurongwa. Naizvozvo, kuitira kuchengetedza diode, takaongorora iyo ICCT nyowani nekuwedzera mamwe maseketi ekunyudza pane yechinyakare IGCT module kuderedza kukanganiswa kwehurongwa.

Nyowani IGCT Zvishandiso: Nekuwedzera kwekuwedzera kunyura maseketi, dhizaini yedu nyowani yeIGCT yakanyanya compact uye ine yakakwira maitiro ekupikisa uye kuvimbika kwakanyanya, saka tinokwanisa kugadzira zvinhu zvekudzivirira zvine kuvimbika kwepamusoro uye simba remuchina. Xd Power System Co., Ltd. iri kufanoferefeta zvinhu zvekudzivirira zveIGCT zvekutora dunhu reYunnan Maitrei chirongwa. Kana iyo dhizaini yakavakirwa paXD Power system scheme, iyo nhamba yeIGCT modules ichaderedzwa neinenge 3% kana ichienzaniswa neIGBT, uye huwandu hwese hwezvinhu zvekudzivirira huchave 2-3 nguva yeIGBT.
