Yintoni iHydrogen Production Rectifier Transformer?

I-Hydrogen Production Rectifier Transformer​ sisixhobo sombane esikhethekileyo esibalulekileyo kwimveliso ye-hydrogen ye-electrolytic, esisebenza njengomqolo weenkqubo zokuguqula amandla eziguqula i-alternating current (AC) ukusuka kwigridi okanye kwimithombo yamandla avuselelekayo ukuya kwi-stable, controlled direct current (DC) efunekayo kwi-electrolysis yamanzi. Indima yayo ephambili kukuvala umsantsa phakathi kwamandla e-AC ane-voltage ephezulu kunye neemfuno ze-DC ezine-voltage ephantsi, ezine-current ephezulu zee-hydrogen electrolyzers (umz., ii-electrolyzers ze-alkaline okanye ze-proton exchange membrane (PEM), ukuqinisekisa ukunikezelwa kwamandla okusebenzayo, okuthembekileyo, kunye nomgangatho ophezulu wokwahlula amanzi abe yi-hydrogen kunye ne-oxygen.

Imisebenzi Engundoqo​

I-transformer yenza imisebenzi emithathu ephambili kwimveliso ye-hydrogen:

Ukuguqulwa kweVolthi: Ihlisa i-AC ene-voltage ephezulu (umz., 10 kV, 35 kV) iye kwi-DC ene-voltage ephantsi (umz., 160 V–592 V) efunekayo kwii-electrolyzers, ezisebenza ngamandla e-DC ukuqhuba i-electrolysis reaction.

Ukuzinziswa koMbane: Kubonelela ngolawulo oluchanekileyo lwe-voltage kunye nolwangoku ukuze kugcinwe umbane ophumayo uzinzile, nokuba kukho utshintsho kwimithombo yamandla avuselelekayo (umz., umoya, ilanga) okanye utshintsho kumthwalo wegridi. Olu zinzo lubalulekile ekuthinteleni umonakalo we-electrolyzer kunye nokuphucula imveliso ye-hydrogen.

Ukunciphisa iHarmonic: Isebenzisa uyilo lwe-multi-pulse (umz., i-12-pulse, i-24-pulse, i-48-pulse, okanye i-96-pulse) ukunciphisa i-harmonic distortion kwi-output current. I-Harmonic—ii-frequency ezingafunekiyo eziveliswa kukulungiswa—zinokonakalisa umgangatho wamandla, zonyuse ilahleko yamandla, kwaye ziphazamise ezinye izixhobo. Ii-Multi-pulse topologies (ezifezekiswa nge-phase-shifted windings okanye ii-parallel bridges) zinciphisa ezi distortion, zithobela imigangatho efana ne-IEEE 519.

Iimpawu zoBugcisa eziPhambili​

Iitransformer zeHydrogen production rectifier zenzelwe ukusebenza kakuhle, ukuthembeka, kunye nokuhambelana nee-electrolyzers. Uyilo lwazo luquka iimpawu ezininzi eziphambili:

Ulungelelwaniso lweeMulti-Pulse: Uyilo oluqhelekileyo luquka iinkqubo ze-12-pulse, 24-pulse, 48-pulse, kunye ne-96-pulse. Umzekelo, i-transformer ye-96-pulse (umz., uthotho lwe-CEEG's ZHSFT) isebenzisa iibhulorho ezininzi ezihambelanayo ezinee-phase-shifted windings ukunciphisa i-total harmonic distortion (THD) ukuya ngaphantsi kwe-10%, ukuqinisekisa ukuhambelana kwegridi kunye nokukhusela ii-electrolyzers kwi-voltage ripple.

Ukusebenza Kakhulu: Iitransformer zanamhlanje zisebenza kakuhle nge-97.5% nangaphezulu xa zigcwele, nto leyo enciphisa inkunkuma yamandla. Oku kuqhutywa zizixhobo ezisisiseko ezilahlekelwa kancinci (umz., intsimbi yesilicon ejonge kwiinkozo) kunye noyilo oluphuculiweyo lwe-winding.

Ulawulo Oluchanekileyo: Idibanisa abatshintshi bempompo abakwimithwalo (OLTC)​ yokulungiswa kwe-coarse voltage (±10% stepwise) kunye nolawulo lwe-thyristor phase-angle​ yokulungiswa kakuhle (ukulungiswa kwemveliso okuqhubekekayo kwe-0–100%). Le nkqubo ye-hybrid iqinisekisa ukuziqhelanisa okungenamthungo neemfuno zenkqubo eguqukayo, ezinje ngotshintsho kuxinzelelo lwe-electrolyte okanye imfuno yemveliso.

Ulwakhiwo Oluqinileyo: Lwakhiwe ukuze lukwazi ukumelana neemeko zokusebenza ezinzima (umz., imozulu yetropiki, uthuli, ukufuma) oluneempawu ezifana nokufakwa kwe-Class H (okumelana ne-180°C), ukupholisa umoya ophoqelelweyo (i-FOA) (kwiindawo ezinobushushu obuphezulu), kunye neendawo ezivalekileyo ezingamelani nokugqwala (uvavanyo lwe-IP54). Ezi mpawu zandisa ubomi benkonzo (ukuya kuthi ga kwiminyaka engama-30) kwaye zinciphisa iimfuno zokugcinwa.

Umthamo Omkhulu Wokuthwala Umthwalo: Yenzelwe ukujongana nomthwalo ogqithisileyo wexeshana (umz., i-20% ngaphezu komthamo olinganisiweyo) ngaphandle kokuphazamisa ukusebenza, ukuqinisekisa ukusebenza okungaphazanyiswa ngexesha lemfuno ephezulu okanye ukuguquguquka kwamandla avuselelekayo.
