Mesebetsi ea Bohlokoa​

Transformer e etsa mesebetsi e meraro ea bohlokoa tlhahisong ea haeterojene:

Phetoho ea Voltage: E theola AC e nang le motlakase o phahameng (mohlala, 10 kV, 35 kV) ho ea ho DC e nang le motlakase o tlase (mohlala, 160 V–592 V) e hlokoang ke li-electrolyzer, tse sebetsang ka matla a DC ho khanna karabelo ea electrolysis.

Ho Tsitsisa Matla: Ho fana ka taolo e nepahetseng ea motlakase le ea hona joale ho boloka tlhahiso e tsitsitseng ea motlakase, esita le har'a liphetoho tsa mehloli ea matla a nchafatsoang (mohlala, moea, letsatsi) kapa liphetoho tsa mojaro oa gridi. Ho tsitsa hona ho bohlokoa ho thibela tšenyo ea electrolyzer le ho ntlafatsa chai ea haeterojene.

Ho Fokotsa Harmonic: E sebedisa meralo ya di-pulse tse ngata (mohlala, 12-pulse, 24-pulse, 48-pulse, kapa 96-pulse) ho fokotsa ho sotha ha harmonic ho phallo ya motlakase. Di-Harmonic—maqhubu a sa batleheng a hlahiswang ke tokiso—di ka senya boleng ba matla, tsa eketsa tahlehelo ya matla, mme tsa sitisa disebediswa tse ding.

Likarolo tsa Bohlokoa tsa Tekheniki​

Li-transformer tsa tlhahiso ea haedrojene li entsoe ka mokhoa o sebetsang hantle, o tšepahalang le o lumellanang le li-electrolyzer. Moralo oa tsona o kenyelletsa likarolo tse 'maloa tse tsoetseng pele:

Litlhophiso tsa Multi-Pulse: Meralo e tloaelehileng haholo e kenyelletsa litsamaiso tsa 12-pulse, 24-pulse, 48-pulse, esita le 96-pulse. Mohlala, transformer ea 96-pulse (mohlala, letoto la CEEG la ZHSFT) e sebelisa marokho a mangata a bapileng a nang le li-winding tse fetotsoeng ka mekhahlelo ho fokotsa ho sotha ho felletseng ha harmonic (THD) ho ea ka tlase ho 10%, ho netefatsa ho lumellana ha grid le ho sireletsa li-electrolyzer ho tsoa ho maqhubu a motlakase.

Bokgoni bo Phahameng: Li-transformer tsa sejoale-joale li fihlella bokgoni ba 97.5% kapa ho feta ha li jarisoa ka botlalo, e leng se fokotsang tšenyo ea matla. Sena se nolofalloa ke thepa ea mantlha e sa lahleheng haholo (mohlala, tšepe ea silicon e shebaneng le lijo-thollo) le meralo e ntlafalitsoeng ea ho kobeha.

Taolo e Nepahetseng: E ​​kopanya di-tap changer tse jarwang (OLTC)​ bakeng sa phetoho ya motlakase o moholo (±10% mohato ka mohato) le taolo ya thyristor phase-angle​ bakeng sa ho lokisa hantle (phetoho e tswelang pele ya tlhahiso ya 0–100%). Sistimi ena e kopaneng e netefatsa ho ikamahanya le ditlhoko tse feto-fetohang tsa tshebetso, tse kang diphetoho tsa mahloriso a electrolyte kapa tlhokeho ya tlhahiso.

Kaho e Matla: E hahiloe ho mamella maemo a thata a ts'ebetso (mohlala, maemo a leholimo a tropike, lerōle, mongobo) ka likarolo tse kang ho thibela mocheso oa Sehlopha sa H (ho hanela mocheso oa 180°C), ho pholisa moea o qobelloang (FOA) (bakeng sa libaka tse nang le mocheso o phahameng), le libaka tse hanelang mafome (tekanyo ea IP54). Likarolo tsena li eketsa bophelo ba ts'ebeletso (ho fihlela lilemo tse 30) le ho fokotsa litlhoko tsa tlhokomelo.

Bokgoni bo Phahameng ba ho Jara Metsi a Mangata: E entswe ho sebetsana le ho jara metswako ya nakwana (mohlala, 20% ho feta bokgoni bo lekantsweng) ntle le ho beha tshebetso kotsing, ho netefatsa tshebetso e sa sitisweng nakong ya tlhokeho e kgolo kapa diphetoho tsa matla a ntjhafatswang.

Litšebeliso Tlhahisong ea Haedrojene​

Li-transformer tsa tlhahiso ea haedrojene li sebelisoa mererong e meholo ea haedrojene e tala le tlhahiso ea haedrojene ea indasteri, haholo-holo tse kopantsoeng le mehloli ea matla a nchafatsoang. Mehlala e kenyelletsa:

Di-transformer di nolofalletsa phetoho e sebetsang hantle ya matla a moya le a letsatsi ho ba hydrogen, e tshehetsang tlhahiso ya ammonia e tala le methanol.

Morero oa Hydrogen e Tala ea Songyuan: E fanoa ke Hitachi Energy, li-transformer tse lokisang li tšehetsa setsi sa matla a nchafatsoang a 3-GW (moea + letsatsi) se fehlang motlakase oa metsi ka motlakase. Moralo o monyane oa li-transformer, tahlehelo e tlase, le khanyetso ea harmonic li netefatsa phepelo e tšepahalang ea motlakase bakeng sa tlhahiso ea haeterojene, e sebelisoang ho kopanya ammonia le methanol.

Dimela tsa Electrolysis ya Diindasteri: Di ​​sebediswa tlhahisong ya chlor-alkali, ho hapa di-electro tsa tshepe, le ditshebetsong tse ding tsa indasteri tse hlokang matla a DC. Mohlala, sistimi ya transformer ya rectifier ya 700 kVA e sebediswang Rephaboliking ya Democratic Republic of the Congo (DRC) e matlafatsa electrolysis bakeng sa ditshebetso tsa indasteri, e nang le tokiso ya thyristor ya pulse ya 12 le OLTC bakeng sa taolo e nepahetseng ya motlakase.
