Tiknoolajiyada cusub ee jilicsan ee toosan iyo codsigeeda walxaha dahaarka

Laga soo bilaabo 1966, Tignoolajiyada EM waxay u heellan tahay cilmi baarista iyo horumarinta agabka dahaarka. Beerista 56 sano ee warshadaha, nidaam cilmi baaris oo weyn ayaa la sameeyay, in ka badan 30 nooc oo agab cusub oo dahaarka ah ayaa la sameeyay, kuwaas oo u adeegaya korontada, mishiinada, batroolka, kiimikooyinka, elektiroonigga, baabuurta, dhismaha, tamarta cusub iyo warshadaha kale. . Waxaa ka mid ah codsigaQalabka dahaarka ee mashiinnada wax-soo-saarka ayaa sidoo kale ah mid ka mid ah tilmaamaha muhiimka ah ee aan diiradda saareyno.

Jiilka cusub ee tignoolajiyada gudbinta DC, gudbinta dabacsanaanta DC waxay la mid tahay gudbinta HVDC qaab ahaan, taas oo wali ka kooban saldhigyada beddelka iyo xadhkaha gudbinta DC. Ka duwan kan hadda jira nooca gudbinta HVDC ee ku salaysan tignoolajiyada wareejinta ee wajiga gacanta lagu hayo, beddelaha gudbinta DC dabacsan waa beddelaha isha korantada (VSC), kaas oo lagu garto isticmaalka aaladaha la beddelan karo (sida caadiga ah IGBT) iyo tignoolajiyada wax-ka-beddelka-sare ee . Sannadihii ugu dambeeyay, gudbinta DC-ga dabacsan ayaa u koraysa xagga darajada iyo awoodda danab sare.

Xaaladda codsiga IGBT: IGBT waxaa ka buuxa tuubo laba-cirifoodka ah oo dahaaran, kaas oo la dami karo, leeyahay faa'iidooyinka khasaaraha yar iyo xakamaynta fudud, waxaana loo tixgelin karaa CPU-da gudbinta tooska ah ee jilicsan. Waqtigan xaadirka ah, IGBT lagu dabaqay mashruuca waa dhammaan badeecooyinka dibadda laga keeno, gaar ahaan ABB iyo Siemens, halka IGBT gudaha oo leh danab sare iyo awood sare uusan lahayn alaab qaangaar ah. Waqtigan xaadirka ah, horumarka deegaanku waa mid gaabis ah, ku-tiirsanaanta soo dejinta ayaa xooggan, khatartuna waa mid aad u ballaaran. Isla mar ahaantaana, qiimaha IGBT wuxuu xisaabiyaa ilaa 30% qiimaha waalka.

Suurtagalnimada IGCT cusub: Iyadoo la eegayo suurtagalnimada hoose ee IGBT ee Shiinaha, waxaan isku dayeynaa inaan ku bedelno IGBT IGCT. Inta jeer ee beddelka, awoodda wadista iyo waxqabadka kale ee IGCT-dhaqameedku way ka hooseeyaan IGBT, laakiin waxay leedahay faa'iidooyin gaar ah xagga awoodda, khasaaraha gobolka, beddelka luminta iyo kharashka (qiimaha badeecadaha leh awood isku mid ah waa qiyaastii 1/2 ee IGBT ). Si kastaba ha noqotee, haddii IGCT-dhaqameedka lagu dabaqo UHV gudbinta awoodda dabacsan, marka IGCT la shido, diode wuxuu dhalin doonaa soo kabashada weyn ee hadda, taas oo saameyn weyn ku yeelan doonta nidaamka. Sidaa darteed, si loo ilaaliyo diode-ka, waxaan baarnay ICCT-da cusub annagoo ku darayna wareegyo nuugista dheeraad ah oo ku saabsan moduleka IGCT-dhaqameedka si loo yareeyo saameynta nidaamka.

Codsiyada cusub ee IGCT: Marka lagu daro wareegyada nuugista dheeraadka ah, naqshadeena cusub ee IGCT waa mid aad u adag oo leh saameyn sare oo iska caabin ah iyo isku halaynta sare, sidaas darteed waxaan soo saari karnaa alaabta dahaarka leh kalsoonida sare ee ilaalinta iyo xoogga farsamada. Nidaamka Korontada ee Xd Co., Ltd. wuxuu horay u baarayaa agabka dahaadhka ee wareegga nuugista IGCT ee mashruuca Yunnan Maitrei. Haddii nashqaduhu uu ku salaysan yahay nidaamka nidaamka Awoodda XD, tirada qaybaha IGCT waa la dhimi doonaa ilaa 3% marka la barbar dhigo IGBT, iyo wadarta cadadka alaabta dahaadhidda waxay noqon doontaa 2-3 jeer ka IGBT.
