Ukufudumeza kwe-induction kusetyenziswa ikakhulu ukunyibilikisa isinyithi, ukugcinwa kobushushu, ukuthambisa, ukuwelda, ukucima, ubushushu, i-diathermy, ukucocwa kwentsimbi engamanzi, unyango lobushushu, ukugoba kombhobho, kunye nokukhula kwekristale.Ukunikezelwa kombane wokungeniswa kuqulethwe yisekethe yokuhlaziya, isekethe ye-inverter, isiphaluka somthwalo, isiphaluka solawulo kunye nokukhusela.
Itekhnoloji yonikezelo lwamandla ombane ophakathi ukufudumeza itekhnoloji elungisa isantya samandla sangoku (50Hz) ukwalathisa amandla emva koko iguqulelwe kumaza omoya aphakathi (400Hz ~ 200kHz) ngokusebenzisa izixhobo zesemiconductor yamandla njenge thyristor, MOSFET okanye IGBT.Iimpawu zetekhnoloji kwiindlela zokulawula eziguquguqukayo, amandla amakhulu okuphuma, kunye nokusebenza okuphezulu kuneyunithi, kwaye kulula ukutshintsha amaza ngokuhambelana nemfuno yokufudumeza.
Umlungisi wezixhobo ezincinci kunye neziphakathi zokubonelela ngombane wamkela ulungiso lwe-thyristor yesigaba sesithathu.Kwizixhobo zamandla aphezulu, ukulungiswa kwe-12-pulse thyristor kuya kusetyenziswa ukuphucula umgangatho wamandla ombane kunye nokunciphisa i-grid-side side harmonic current.Iyunithi inverter amandla iqulunqwe high-voltage high-yangoku fast switch thyristor parallel ke series edityanisiweyo ukuqonda imveliso amandla aphezulu.
I-Inverter kunye nesekethe ye-resonant inokwahlulwa ibe ziindidi ezimbini ngokweempawu zesakhiwo: 1) uhlobo lwe-resonant parallel, 2) uhlobo lwe-resonant series.
Uhlobo lwe-resonant oluhambelanayo: i-high-voltage high-current water-cooled thyristor (SCR) isetyenziselwa ukwenza iyunithi yamandla e-inverter yangoku, kunye nokukhutshwa kwamandla aphezulu kufezekiswa yi-superposition of thyristors.Isekethe ye-resonant ngokuqhelekileyo isebenzisa isakhiwo esipheleleyo se-resonance parallel, iphinda ikhethe i-double-voltage okanye imo ye-transformer ukunyusa i-voltage kwi-inductor ngokweemfuno ezahlukeneyo, ezisetyenziswa ikakhulu kwinkqubo yokufudumala.
Uhlobo lwe-resonant Series: i-high-voltage high-current water-cooled thyristor (SCR) kunye ne-diode ekhawulezayo isetyenziselwa ukwenza i-voltage-type inverter power unit, kunye nemveliso yamandla aphezulu ifunyenwe yi-superposition ye-thyristors.Isekethe ye-resonance isebenzisa uchungechunge lwe-resonance structure, kwaye i-transformer yamkelwa ukuba ihambelane nemfuno yomthwalo.Ukongeza kuncedo lwamandla aphezulu kwicala leGridi, uluhlu olubanzi lohlengahlengiso lwamandla, ukusebenza kakuhle kokufudumeza kunye nezinga eliphezulu lempumelelo yokuqalisa, iye yasetyenziswa ngokubanzi nangakumbi kwiminyaka yangoku kwaye isetyenziswa ikakhulu kwinkqubo yokunyibilika.
Emva kokuphuculwa kwenkqubo yokuvelisa, i-Runau eyenziwe ngokukhawuleza i-thyristor yokutshintsha isebenzisa i-neutron radiation kunye nezinye iinkqubo zokunciphisa ngakumbi ixesha lokucima kwaye umthamo wamandla uphuculwe ngenxa yoko.
Ukufudumeza okuphakathi konikezelo lwamandla ombane kuthatha i-thyristor njengoko isixhobo samandla esiphambili sigubungele onke amasimi ngokusebenza rhoqo ngaphantsi kwe-8kHz.Umthamo wamandla ophumayo wahlulwe ube ngama-50, 160, 250, 500, 1000, 2000, 2500, 3000kW, 5000KW, 10000KW frequency yokusebenza yi-200Hz, 400Hz, 1kHz, 2.4kHz, 2.4kHz, 2.4kHz.Iitoni ezili-10, iitoni ezili-12, iitoni ezingama-20 zokunyibilika kwentsimbi kunye nokugcinwa kwe-thermal, izixhobo eziphambili zamandla kunikezelo lwamandla oluphakathi.Ngoku awona mandla emveliso aphezulu afika kwi-20000KW ye-40Ton.Kwaye i-thyristor yeyona nto iphambili yokuguqulwa kwamandla kunye necandelo lokuguqula eliza kusetyenziswa.
