Induction incibilikisa isithando somlilo ukubala amandla

1. Ipharamitha ukubala thyristor

Amandla esithandweni sokushisa ipayipi lensimbi ngu-1500KW, futhi ulayini ongenayo oklanyelwe ugesi ungu-500V. Ngemva kokubala, idatha elandelayo ingatholwa.

I-DC voltage Ud=1.35×500=675V

I-DC yamanje Id=1500000÷675=2200A

I-voltage yefrikhwensi emaphakathi US=1.5×Ud =1000V

Isilinganiso samanje se-silicon rectifier IF=0.38×Id÷2÷0.85=491A

(Ukuhlukaniswa ngo-2 kufomula engenhla kungenxa yokuthi kukhona amasethi amabili ezingxenye ezifanayo zokulungisa)

Isilinganiso se-silicon rectifier voltage UV=1.414×UL=1.414×500=707V

I-silicon ye-inverter ilinganiselwe manje IF=Id/2=1100A

I-silicon eguquguqukayo elinganiselwe i-voltage UV=1.414×US=1414V

2. Isikimu sokukhetha semodeli ye-SCR

I-Rectifier SCR ikhetha i-KP1500A/2000V, okungukuthi, yamanje elinganiselwe ngu-1500A, futhi i-voltage elinganiselwe ingu-2000V. Uma kuqhathaniswa nenani le-theoretical, i-voltage margin iyizikhathi ezingu-2.26, kanti umkhawulo wamanje uyizikhathi ezingu-2.43.

I-inverter thyristor KK2500A/2000V yomthombo wamandla wefrikhwensi ephakathi, okungukuthi, yamanje elinganiselwe ngu-2500A, futhi i-voltage elinganiselwe ingu-2000V. Ngaphezu kwalokho, i-silicon inverter ixhunywe ebhulohweni le-inverter ekuxhumekeni kochungechunge lwe-silicon kabili, ukuze i-voltage elinganiselwe yangempela ye-thyristor engalweni ngayinye yebhuloho le-inverter ibe ngu-5000V. Uma kuqhathaniswa nenani le-theoretical, i-voltage margin iyizikhathi ezingu-2.26, kanti umkhawulo wamanje uyizikhathi ezingu-2.15.

3. IF resonant capacitor cabinet

I-intermediate frequency resonant capacitor yale sethi yamakhabethe e-capacitor wonke ama-electrothermal capacitor akhiqizwa i-Xin’anjiang Power Capacitor Factory, imodeli i-RFM2 1.0 -2000-1.0S. Umthamo wayo ngu-2000KVar, futhi imvamisa yokusebenza ingu-1000Hz.

4. Amandla esithando somlilo esincibilikayo abalwa njenge-pw=DC voltage×DC yamanje
