Yuav ua li cas xaiv thyristor rau induction melting rauv?
Yuav ua li cas xaiv thyristor rau induction melting rauv?
Nyob rau hauv lub zog tsim txheej txheem ntawm lub induction melting rauv, yuav ua li cas xaiv qhov tsim nyog inverter thyristor raws li daim ntawv thov tiag tiag tuaj yeem ua raws li cov hauv qab no:
1. Xaiv lub sijhawm tawm raws li kev ua haujlwm zaus ntawm induction melting rauv fais fab mov:
a) KK-hom thyristor nrog lub sijhawm xaiv tawm ntawm 20µs-45µs ntawm qhov zaus ntawm 100HZ-500HZ.
b) KK-hom thyristor nrog lub sijhawm xaiv tawm ntawm 18µs-25µs ntawm qhov zaus ntawm 500HZ-1000HZ.
c) KK-hom thyristor nrog zaus ntawm 1000HZ-2500HZ thiab xaiv tawm lub sijhawm ntawm 12µs-18µs.
d) KKG hom thyristor nrog xaiv off-time ntawm 10µs-14µs ntawm zaus 2500Hz-4000Hz.
e) KA-type thyristor nrog zaus ntawm 4000HZ-8000HZ thiab xaiv lub sijhawm tig tawm ntawm 6µs-9µs.
2. Xaiv qhov hluav taws xob tiv taus thiab ntsuas tam sim no raws li lub zog tso tawm ntawm lub qhov cub induction melting:
Raws li qhov theoretical xam ntawm lub parallel choj inverter Circuit Court ntawm induction melting rauv, tam sim no ntws los ntawm txhua induction melting rauv thyristor yog 0.455 npaug ntawm tag nrho cov tam sim no. Xav tias muaj cov npoo txaus, qhov loj tib yam li qhov ntsuas tam sim no feem ntau yog xaiv. thyristor.
a) Lub thyristor nrog ib qho kev xaiv tam sim no ntawm 300A / 1400V nrog lub zog ntawm 50KW–100KW. (380V ua ntej voltage)
b) SCR nrog xaiv tam sim no ntawm 500A / 1400V nrog lub zog ntawm 100KW-250KW. (380V ua ntej voltage)
c) SCR nrog xaiv tam sim no ntawm 800A / 1600V nrog lub zog ntawm 350KW-400KW. (380V ua ntej voltage)
d) SCR nrog xaiv tam sim no ntawm 1500A / 1600V nrog lub zog ntawm 500KW-750KW. (380V ua ntej voltage)
e) SCR nrog ib qho kev xaiv tam sim no ntawm 1500A / 2500V nrog lub zog ntawm 800KW-1000KW. (660V ua ntej voltage)
f) SCR nrog xaiv tam sim no ntawm 2000A / 2500V nrog lub zog ntawm 1200KW-1600KW. (660V ua ntej voltage)
g) SCR ntawm kev xaiv tam sim no 2500A / 3000V nrog lub zog ntawm 1800KW-2500KW. (1250V theem-hauv voltage)
