Dab tsi yog Hydrogen Production Rectifier Transformer?

Lub Tshuab Hloov Fais Hydrogen Production Rectifier yog ib lub cuab yeej hluav taws xob tshwj xeeb uas tseem ceeb rau kev tsim cov hydrogen electrolytic, ua lub hauv paus tseem ceeb ntawm cov txheej txheem hloov pauv hluav taws xob uas hloov cov hluav taws xob hloov pauv (AC) los ntawm lub grid lossis cov khoom siv hluav taws xob rov ua dua tshiab mus rau hauv cov hluav taws xob ncaj qha (DC) uas ruaj khov, tswj tau uas xav tau rau kev siv dej electrolysis. Nws lub luag haujlwm tseem ceeb yog txuas qhov sib txawv ntawm cov hluav taws xob AC hluav taws xob siab thiab cov hluav taws xob qis, cov hluav taws xob siab DC uas xav tau ntawm cov tshuab hluav taws xob hydrogen electrolyzers (piv txwv li, alkaline lossis proton exchange membrane (PEM) electrolyzers), kom ntseeg tau tias muaj kev muab hluav taws xob zoo, txhim khu kev qha, thiab zoo rau kev faib dej ua hydrogen thiab oxygen.

Cov Haujlwm Tseem Ceeb

Lub transformer ua peb lub luag haujlwm tseem ceeb hauv kev tsim hydrogen:

Kev Hloov Hluav Taws Xob: Txo cov hluav taws xob AC siab (piv txwv li, 10 kV, 35 kV) mus rau DC qis (piv txwv li, 160 V–592 V) uas cov electrolyzers xav tau, uas ua haujlwm ntawm lub zog DC los tsav cov tshuaj electrolysis.

Kev Ruaj Ntseg Fais Fab: Muab kev tswj hwm qhov hluav taws xob thiab tam sim no kom meej kom tswj tau qhov tso zis hluav taws xob ruaj khov, txawm tias muaj kev hloov pauv ntawm cov khoom siv hluav taws xob rov ua dua tshiab (piv txwv li, cua, hnub ci) lossis kev hloov pauv ntawm lub zog hluav taws xob. Qhov kev ruaj khov no yog qhov tseem ceeb los tiv thaiv kev puas tsuaj ntawm electrolyzer thiab ua kom zoo dua qhov tso zis hydrogen.

Kev Tswj Xyuas Kom Tseeb: Muab cov khoom hloov pauv ntawm qhov chaw thauj khoom (OLTC) rau kev hloov kho qhov hluav taws xob loj (± 10% kauj ruam) thiab thyristor theem-lub kaum sab xis rau kev kho kom zoo (kev hloov kho qhov tso zis txuas ntxiv 0–100). Lub kaw lus sib xyaw no ua kom muaj kev hloov kho kom zoo rau cov txheej txheem xav tau, xws li kev hloov pauv ntawm cov electrolyte concentration lossis kev thov ntau lawm.

Kev Tsim Kho Ruaj Khob: Ua kom tiv taus cov xwm txheej ua haujlwm hnyav (piv txwv li, huab cua sov, hmoov av, av noo) nrog rau cov yam ntxwv xws li Chav Kawm H rwb thaiv tsev (tiv taus 180 ° C), yuam roj-cua txias (FOA) (rau cov chaw kub siab), thiab cov thawv tiv taus xeb (IP54 qib). Cov yam ntxwv no ua rau lub neej ua haujlwm ntev dua (txog li 30 xyoo) thiab txo qhov xav tau kev saib xyuas.

Muaj Peev Xwm Ntau Dhau: Tsim los tswj cov kev thauj khoom ntau dhau ib ntus (piv txwv li, 20% siab dua qhov ntsuas peev xwm) yam tsis muaj kev cuam tshuam rau kev ua haujlwm, xyuas kom meej tias kev ua haujlwm tsis cuam tshuam thaum muaj kev thov ntau lossis kev hloov pauv ntawm lub zog rov ua dua tshiab.
