Imilinganiselo yokukhetha i-Thyristor ye-1000kw ukuchithwa kwesithando somlilo

Umbane womgca ongenayo oyilelweyo yi-380V, kwaye le datha ilandelayo inokufunyanwa ngokubala:

Umbane weDC Ud=1.35×380V=510V

DC yangoku Id=1000000÷510=1960A

Amandla ombane aphakathi Us=1.5×Ud =765V

I-silicon ehlaziyiweyo yangoku i-IKP=0.38×Id=745A

Umlinganiselo wombane wokulungisa isilicon UV=1.414×UL=1.414×510V=721V

I-silicon yokuguqula imilinganiselo yangoku i-Ikk=0.45×19600=882A

I-silicon yokuguqula umlinganiselo wombane UV=1.414×Us=1082V

Iskimu sokukhetha imodeli ye-SCR: khetha i-Xianfan Taiji SCR:

Ngenxa yokuba ithatha i-6-pulse single rectifier output, i-SCR yokuhlaziya ikhetha i-KP2000A / 1400V (i-6 iyonke), oko kukuthi, i-current rated yi-2000A kunye ne-voltage elinganisiweyo yi-1400V. Xa kuthelekiswa nexabiso lethiyori, umda we-voltage ngamaxesha angama-1.94 kwaye umda wangoku ungamaxesha angama-2.68.

I-inverter thyristor ikhetha i-KK2500A / 1600V (ezine zizonke), oko kukuthi, i-current rated yi-2500A, kunye ne-voltage elinganisiweyo yi-1600V. Xa kuthelekiswa nexabiso lethiyori, umda we-voltage ngamaxesha angama-1.48, kwaye umda wangoku ungamaxesha angama-2.83.
