Ingqiqo eqhelekileyo ye ukufudumeza iziko

1. Ukunikezelwa kwamandla kwesithando sokufudumala kwe-induction i-current-phase alternating current, i-frequency yi-50Hz, kunye ne-voltage ye-line engenayo yi-380V. Kwiziko zokufudumeza zamandla aphezulu, amandla ombane anokuba yi-660V, 750V, 950V, njl.

2. I-furnace yokufudumeza i-induction inikwe amandla yi-transformer, enokuthi ihlulwe ibe yintlobo ezimbini: i-transformers eyomileyo kunye ne-oil-cooled transformers ngokweendlela ezahlukeneyo zokupholisa. Kwi ukufudumeza iziko kwishishini, sicebisa ii-oyile ezipholileyo zokulungisa iziguquli.

3. Ngaphantsi kwe-voltage elinganisiweyo okanye umthwalo olinganisiweyo, amandla okukhutshwa kwesithando sokufudumala kwesithando somlilo singalungiswa kakuhle kwaye ngokuqhubekayo, kwaye uluhlu lohlengahlengiso luyi-5% -100% yamandla alinganisiweyo;

4. Ikhabhinethi yokunikezelwa kwamandla okuguqulwa kwamaza ombane yesithando sokufudumala sokufudumala siyinxalenye ephambili, ehlanganiswe ngamacandelo amabini: i-rectifier / inverter. Umsebenzi wenxalenye yokuhlaziya yinkqubo yokuguqula i-50HZ yangoku eguqukayo ibe yi-pulsating yangoku. Ngokutsho kwenani le-pulses yokulungiswa, inokwahlulwa ibe yi-6-pulse rectification, i-12-pulse rectification, kunye ne-24-pulse rectification. Emva kokulungiswa, i-reactor egudileyo iya kudibaniswa ngokulandelelana kunye nepali echanekileyo. Umsebenzi wecandelo le-inverter kukuguqula umbane othe ngqo owenziwe ngokulungiswa kwi-intermediate frequency alternating current kwaye unikeze amandla kwi-coil induction.

5. Xa i-voltage ye-output ye-oven induction yokufudumala idlula amaxesha angama-1.1-1.2 ombane ophezulu wokukhupha okanye idlula ixabiso lokumisela umbane, inkqubo yokukhusela i-overvoltage iya kwenza ukuba isixhobo siyeke ukusebenza ngokuzenzekelayo kwaye sikhuphe isignali ye-alamu – khanyisa Ukukhanya kwesalathisi esiphezulu kwibhokisi yesixhobo.

6. Ikhabhinethi ye-capacitor yesithando sokufudumala sokufudumala sisixhobo esinika imbuyekezo yamandla asebenzayo kwi-coil induction. Inokuqondwa ngokulula ukuba inani le-capacitance lichaphazela ngokuthe ngqo amandla ezixhobo. I-parallel resonance induction i-furnace yokufudumala inohlobo olulodwa kuphela lwe-resonance capacitor (i-capacitor yokufudumeza yombane), ngelixa i-series resonance induction i-furnace ine-filter capacitor ngaphezu kwe-resonance capacitor (i-capacitor yokufudumala yombane).

7. Xa ibhuloho ye-inverter yesithando sokufudumala somlilo idibaniswe ngokuthe ngqo kunye ne-short-circuited, inkqubo yokukhusela iya kwenza ngokukhawuleza ukumisa isixhobo ngokuzenzekelayo, kwaye ithumele isignali yokubonisa i-overcurrent – khanyisa ukukhanya kwe-overcurrent indicator kwibhokisi yesixhobo.

8. Xa uxinzelelo olusebenzayo lwenkqubo yokupholisa amanzi yesithando sokufudumala se-induction iphantsi kunexabiso elithile, izixhobo zokufudumeza induction, ukucima izixhobo zokunyanga ubushushu, kunye nokucima kunye nomgca wokuvelisa ubushushu bokushisa kunokumisa ngokuzenzekelayo kwaye kukhanyise uxinzelelo lwamanzi. isalathisi kwindawo yolawulo.

9. Isixhobo sokuguqula rhoqo se ukufudumeza iziko ithatha i-thyristor SCR, eyona nxalenye yecandelo lonikezelo lwamandla. Ukusebenza kwe-thyristor ekhethiweyo kuya kuchaphazela ngokuthe ngqo ukusebenza kwezixhobo. Ulwahlulo oluqhelekileyo lwethyristor,

1) KP uhlobo thyristor eqhelekileyo, esetyenziswa ngokubanzi ukulungisa;

2) KK chwetheza i-thyristor ekhawulezayo, esetyenziswa ngokubanzi kwi-inverter;

1. Uhlobo lwe-KF lwe-asymmetric thyristor luhlobo olutsha lwe-thyristor oluphuhliswe kwiminyaka yakutshanje, olusetyenziswa kwizixhobo ze-inverter series.
