Thyristor xaiv parameters rau 1000kw induction melting rauv

Cov kab hluav taws xob tsim tawm yog 380V, thiab cov ntaub ntawv hauv qab no tuaj yeem tau los ntawm kev suav:

DC voltage Ud = 1.35 × 380V = 510V

DC tam sim no ID = 1000000 ÷ 510 = 1960A

Qhov nruab nrab zaus voltage Us = 1.5 × Ud = 765V

Rated silicon rectifier tam sim no IKP = 0.38 × Id = 745A

Rated silicon rectifier voltage UV = 1.414 × UL = 1.414 × 510V = 721V

Inverter silicon ntsuas tam sim no Ikk = 0.45 × 19600 = 882A

Inverter silicon ntsuas voltage UV = 1.414 × Us = 1082V

SCR qauv xaiv qauv: xaiv Xiangfan Taiji SCR:

Vim tias nws tau txais 6-pulse ib leeg rectifier tso zis, lub rectifier SCR xaiv KP2000A / 1400V (tag nrho ntawm 6), uas yog, qhov ntsuas tam sim no yog 2000A thiab qhov ntsuas hluav taws xob yog 1400V. Piv nrog rau tus nqi theoretical, qhov voltage margin yog 1.94 npaug thiab qhov tam sim no margin yog 2.68 npaug.

Lub inverter thyristor xaiv KK2500A / 1600V (plaub nyob rau hauv tag nrho), uas yog, qhov ntsuas tam sim no yog 2500A, thiab qhov ntsuas hluav taws xob yog 1600V. Piv nrog rau tus nqi theoretical, qhov voltage margin yog 1.48 npaug, thiab cov paj tam sim no yog 2.83 npaug.
