Ukuchithwa kwesithando somlilo ukubala amandla

1. Ukubalwa kweParameter ye-thyristor

Amandla ombhobho wensimbi wokufudumeza isithando somlilo yi-1500KW, kwaye i-voltage yombane ongenayo eyilelwe yi-500V. Emva kokubala, le datha ilandelayo inokufumaneka.

Umbane weDC Ud=1.35×500=675V

DC yangoku Id=1500000÷675=2200A

Amandla ombane aphakathi e-US=1.5×Ud =1000V

I-silicon ehlaziyiweyo yangoku IF=0.38×Id÷2÷0.85=491A

(Ukwahlulahlulwa ngo-2 kule fomula ingasentla kungenxa yokuba kukho iiseti ezimbini zamalungu afanayo okulungisa)

Umgangatho wombane wokulungisa isilicon UV=1.414×UL=1.414×500=707V

I-silicon yokuguqula umlinganiselo wangoku IF=Id/2=1100A

I-silicon yokuguqula umlinganiselo wombane UV=1.414×US=1414V

2. Iskimu sokukhetha imodeli ye-SCR

I-Rectifier SCR ikhetha i-KP1500A / 2000V, oko kukuthi, i-current rated yi-1500A, kunye ne-voltage elinganisiweyo yi-2000V. Xa kuthelekiswa nexabiso lethiyori, umda we-voltage ngamaxesha angama-2.26, kwaye umda wangoku ungamaxesha angama-2.43.

I-inverter thyristor KK2500A / 2000V ye-intermediate frequency power supply, oko kukuthi, i-current rated yi-2500A, kunye ne-voltage elinganisiweyo yi-2000V. Ukongeza, i-silicon ye-inverter iqhagamshelwe kwibhulorho ye-inverter kuqhagamshelo lwe-silicon ephindwe kabini, ukuze i-voltage eyiyo yokulinganisa ye-thyristor kwingalo yebhulorho ye-inverter yi-5000V. Xa kuthelekiswa nexabiso lethiyori, umda we-voltage ngamaxesha angama-2.26, kwaye umda wangoku ungamaxesha angama-2.15.

3. UKUBA ikhabhinethi ye-resonant capacitor

I-intermediate frequency resonant capacitors yale seti yeekhabhathi ze-capacitor zonke ii-electrothermal capacitors eziveliswe yi-Xin’anjiang Power Capacitor Factory, imodeli yi-RFM2 1.0 -2000-1.0S. Umthamo wayo ngu-2000KVar, kwaye i-frequency yokusebenza yi-1000Hz.

4. Amandla eziko lokunyibilikisa induction ibalwa njenge pw=DC voltage×DC yangoku.
