Imingcele yokukhetha i-Thyristor ka-1000kw ukuchithwa kwesithando somlilo

I-voltage yomugqa ongenayo eklanyelwe ingu-380V, futhi idatha elandelayo ingatholwa ngokubala:

I-DC voltage Ud=1.35×380V=510V

I-DC yamanje Id=1000000÷510=1960A

I-voltage yefrikhwensi emaphakathi Us=1.5×Ud =765V

Isilungisi se-silicon esilinganiselwe samanje se-IKP=0.38×Id=745A

Isilinganiso se-silicon rectifier voltage UV=1.414×UL=1.414×510V=721V

I-silicon eguqulayo ilinganiselwe i-Ikk yamanje = 0.45×19600=882A

Isiguquli se-silicon esikalwe nge-voltage UV=1.414×Us=1082V

Isikimu sokukhetha imodeli ye-SCR: khetha i-Xiangfan Taiji SCR:

Ngenxa yokuthi yamukela okukhiphayo kwesilungisisi esisodwa esingu-6, i-SCR elungisayo ikhetha i-KP2000A/1400V (inani eliyi-6), okungukuthi, okwamanje okulinganiselwe ngu-2000A kanye ne-voltage elinganiselwe ngu-1400V. Uma kuqhathaniswa nenani le-theoretical, i-voltage margin iyizikhathi ezingu-1.94 kanti umkhawulo wamanje uyizikhathi ezingu-2.68.

I-inverter thyristor ikhetha i-KK2500A/1600V (ezine sezizonke), okungukuthi, isilinganiso samanje singu-2500A, kanti i-voltage elinganiselwe yi-1600V. Uma kuqhathaniswa nenani le-theoretical, i-voltage margin iyizikhathi ezingu-1.48, kanti umkhawulo wamanje uyizikhathi ezingu-2.83.
