Amadivayisi we-Power Electronics We-Induction Heating
Ukushisa kwe-induction kusetshenziselwa ukuncibilikisa insimbi, ukulondolozwa kokushisa, ukumomotheka, ukuwelda, ukucima, ukufuthelana, i-diathermy, ukuhlanzwa kwensimbi ewuketshezi, ukwelashwa kokushisa, ukugoba ipayipi nokukhula kwe-crystal. Ukunikezwa kwamandla we-induction kuqukethe isekethe lokulungisa, isekethe ye-inverter, isifunda sokulayisha, isifunda sokulawula nokuvikela.
Itheknoloji yokuphakelwa kwamandla okuvama okuphakathi kokushisa kwe-induction ubuchwepheshe obulungisa imvamisa yamandla eshintshashintshayo yamanje (50Hz) ukuhambisa amandla bese iguqula ibe imvamisa emaphakathi (400Hz ~ 200kHz) ngamadivayisi we-semiconductor wamandla afana ne-thyristor, MOSFET noma i-IGBT. Ubuchwepheshe bufaka ezindleleni zokulawula eziguquguqukayo, amandla amakhulu wokukhipha, nokusebenza kahle kuneyunithi, futhi kulula ukushintsha imvamisa ngokuya ngemfuneko yokushisa.
Isilungisi semishini yokuhambisa ugesi emincane naphakathi samukela ukulungiswa kwezigaba ezintathu kwe-thyristor. Okokusebenza kwamandla kagesi aphezulu, ukulungiswa kwe-12-pulse thyristor kuzosetshenziswa ukwenza ngcono izinga lamandla kagesi kanye nokunciphisa i-harmonic yamanje. Iyunithi yamandla we-inverter yakhiwe ngamandla we-high-voltage high-current switch switch thyristor parallel bese uchungechunge luxhunywe ukubona amandla aphezulu aphumayo.
Inverter nesekethe resonant zingahlukaniswa zibe izinhlobo ezimbili ngokuya izakhiwo kwesakhiwo: 1) parallel uhlobo isoni, 2) uchungechunge uhlobo resonant.
Uhlobo lwe-resonant olufanayo: i-high-voltage high-current water-cooled thyristor (SCR) esetshenziselwa ukwakha iyunithi yamandla we-inverter yamanje, futhi ukukhishwa kwamandla okuphezulu kutholwa yi-superristation yama-thyristors. Isifunda esi-resonant ngokuvamile sisebenzisa isakhiwo se-resonance esiphelele, futhi sikhetha i-double-voltage noma i-transformer mode ukukhuphula i-voltage ku-inductor ngokuya ngemfuneko ehlukile, ikakhulukazi esetshenziswa kunqubo yokwelashwa kokushisa.
Uhlobo lwe-resonant series: i-thyristor (i-high-voltage high-current water-cooled thyristor (i-SCR) ne-diode esheshayo isetshenziselwa ukwakha iyunithi yamandla we-inverter yamandla kagesi, futhi ukukhishwa kwamandla okuphezulu kutholwa yi-superristation yama-thyristors. Isifunda se-resonance sisebenzisa isakhiwo se-resonance yochungechunge, futhi isiguquli samukelwa ukufanisa imfuneko yomthwalo. Ngaphezu kwezinzuzo zamandla aphezulu ku-Grid-side, ububanzi bokulungiswa kwamandla, ukusebenza kahle kokushisa okuphezulu kanye nezinga eliphezulu lokuphumelela, sekuyasetshenziswa kabanzi eminyakeni yamanje futhi kusetshenziswa kakhulu kwinqubo yokuncibilika.
Ngemuva kokuthuthuka kwenqubo yokukhiqiza, iRunau eyenziwe nge-switch switch thyristor isebenzisa imisebe ye-neutron nezinye izinqubo ukuqhubeka nokunciphisa isikhathi sokucisha futhi amandla kagesi ayathuthukiswa ngenxa yalokho.
Ukunikezwa kwamandla we-induction heat frequency medium supply isebenzisa i-thyristor njengoba idivaysi enkulu yamandla ihlanganise zonke izinkambu ngemvamisa yokusebenza engaphansi kwe-8kHz. Amandla wokukhipha ahlukaniswe ngama-50, 160, 250, 500, 1000, 2000, 2500, 3000kW, 5000KW, 10000KW imvamisa yokusebenza ingu-200Hz, 400Hz, 1kHz, 2.5kHz, 4kHz, 8kHz. Amathani ayi-10, amathani ayi-12, amathani angama-20 okuncibilika kwensimbi nokubhuka okushisayo, okokusebenza kwamandla amakhulu amandla kagesi aphakathi nendawo. Manje amandla okuphuma aphezulu afika kuma-20000KW we-40Ton. Futhi i-thyristor ingukhiye wokuguqula amandla nengxenye yokuguqula okufanele isetshenziswe.
