Mofani oa Lefatše oa Tšireletso ea Tikoloho

Theknoloji e ncha e bonolo e otlolohileng le ts'ebeliso ea eona ho thepa ea ho pata

Ho tloha ka 1966, EM Technology e ikemiselitse ho etsa lipatlisiso le nts'etsopele ea lisebelisoa tsa ho kenya letsoho. Ho lema lilemo tse 56 indastering, ho theiloe sistimi e kholo ea lipatlisiso tsa mahlale, mefuta e fetang 30 ea lisebelisoa tse ncha tsa ho kenya e se e ntlafalitsoe, e sebeletsa matla a motlakase, mochini, peterole, lik'hemik'hale, lisebelisoa tsa elektroniki, likoloi, kaho, matla a macha le liindasteri tse ling. . Har'a bona, kopoea lisebelisoa tsa ho kenya letsoho mochining oa ho bopa le tsona ke e 'ngoe ea litsela tsa bohlokoa tseo re tsepamisitseng maikutlo ho tsona.

E le moloko o mocha oa theknoloji ea phetisetso ea DC, phetisetso ea DC e feto-fetohang e tšoana le phetisetso ea HVDC ka sebopeho, e ntseng e entsoe ka liteishene tsa converter le mehala ea phetisetso ea DC. Ho fapana le phetisetso ea hona joale ea mohloli oa HVDC e thehiloeng ho thekenoloji ea phalliso e laoloang ke mohato, sesebelisoa se feto-fetohang sa DC ke sesebelisoa sa motlakase sa motlakase (VSC), se tšoauoang ka tšebeliso ea lisebelisoa tse fetohang (hangata IGBT) le theknoloji ea ho feto-fetoha ha maemo a holimo. . Lilemong tsa morao tjena, phetisetso e feto-fetohang ea DC e ntse e tsoela pele ho ea maemong a phahameng a motlakase le bokhoni.

Boemo ba kopo ea IGBT: IGBT e tletse insulated heke bipolar tube, e ka tima, e na le melemo ea ho tahlehelo e nyenyane le taolo e bonolo, 'me e ka nkoa e le CPU ea phetisetso e bonolo e tobileng. Hajoale, IGBT e kentsoeng morerong ona ke lihlahisoa tsohle tse tsoang kantle ho naha, haholo-holo ABB le Siemens, athe IGBT ea lapeng e nang le matla a phahameng le matla a phahameng ha e na lihlahisoa tse holileng. Hajoale, tsoelo-pele ea libaka e ea lieha, ho itšetleha ka thepa ea kantle ho naha ho matla, 'me kotsi e batla e le kholo. Ka nako e ts'oanang, litšenyehelo tsa IGBT li nka hoo e ka bang 30% ea litšenyehelo tsa valve.

Ho khoneha ha IGCT e ncha: Ka lebaka la ho khoneha ha IGBT naheng ea Chaena, re leka ho fetola IGBT ka IGCT. Maqhubu a ho fetoha, matla a ho khanna le ts'ebetso e 'ngoe ea IGCT ea setso e tlase ho IGBT, empa e na le melemo e itseng ka bokhoni, tahlehelo ea naha, tahlehelo ea ho fetoha le litšenyehelo (theko ea lihlahisoa tse nang le matla a tšoanang e ka bang 1/2 ea IGBT. ). Leha ho le joalo, haeba IGCT ea setso e sebelisoa ho phetisetso ea matla ea UHV e feto-fetohang, hang ha IGCT e buletsoe, diode e tla hlahisa motlakase o moholo oa ho hlaphoheloa, o tla ba le tšusumetso e kholo tsamaisong. Ka hona, e le ho sireletsa diode, re ile ra batlisisa ICCT e ncha ka ho eketsa lipotoloho tse eketsehileng tsa ho monya mojuleng oa setso oa IGCT ho fokotsa tšusumetso tsamaisong.

Likopo tse Ncha tsa IGCT: Ka kenyelletso ea li-circuits tse eketsehileng tsa ho monya, moralo oa rona o mocha oa IGCT o kopane haholoanyane 'me o na le ts'usumetso e phahameng le ts'epahalo e phahameng, kahoo re ka etsa lisebelisoa tsa ho kenya letsoho ka ts'epahalo e phahameng le matla a mochini. Xd Power System Co., Ltd. e ntse e etsa lipatlisiso tsa lisebelisoa tsa ho kenya letsoho bakeng sa potoloho ea ho monya ea IGCT bakeng sa projeke ea Yunnan Maitrei. Haeba moralo o thehiloe ho moralo oa sistimi ea XD Power, palo ea li-module tsa IGCT e tla fokotsoa ka hoo e ka bang 3% ha e bapisoa le IGBT, 'me kakaretso ea lisebelisoa tsa ho kenya letsoho e tla ba makhetlo a 2-3 ho feta a IGBT.
