Induction inonyunguduka vira simba kuverenga

1. Parameter kuverenga ye thyristor

Simba resimbi pombi yekudziisa choto i1500KW, uye rakagadzirirwa rinopinda mutsetse voltage i500V. Mushure mekuverenga, iyo inotevera data inogona kuwanikwa.

DC voltage Ud=1.35×500=675V

DC current Id=1500000÷675=2200A

Yepakati frequency voltage US=1.5×Ud =1000V

Yakatemerwa nesilicon rectifier ikozvino IF=0.38×Id÷2÷0.85=491A

(Kupatsanurwa ne2 mune iri pamusoro fomula imhaka yekuti kune maviri seti eakafanana ekugadzirisa zvikamu)

Rated silicon rectifier voltage UV = 1.414 × UL = 1.414 × 500 = 707V

Inverter silicon yakayerwa ikozvino IF=Id/2=1100A

Inverter nesilicon rated voltage UV=1.414×US=1414V

2. Kusarudzwa kwechirongwa cheSCR modhi

Iyo rectifier SCR inosarudza KP1500A/2000V, kureva kuti, yakayerwa ikozvino i1500A, uye yakayerwa voltage i2000V. Kana ichienzaniswa neiyo theoretical value, iyo voltage margin ndeye 2.26 nguva, uye ikozvino margin ndeye 2.43 nguva.

Iyo inverter thyristor KK2500A/2000V yepakati frequency simba rekupa, kureva kuti, yakayerwa ikozvino ndeye 2500A, uye yakayerwa voltage ndeye 2000V. Uye zvakare, iyo inverter silicon yakabatana kune inverter bhiriji mune kaviri-silicon yakatevedzana yekubatanidza, kuitira kuti iyo chaiyo yakatarwa voltage ye thyristor pane yega inverter bhiriji ruoko i5000V. Kana ichienzaniswa neiyo theoretical value, iyo voltage margin ndeye 2.26 nguva, uye ikozvino margin ndeye 2.15 nguva.

3. KANA resonant capacitor cabinet

Iyo yepakati frequency resonant capacitors yeiyi seti ye capacitor makabati ese e electrothermal capacitors anogadzirwa neXin’anjiang Power Capacitor Factory, iyo modhi iRFM2 1.0 -2000-1.0S. Kugona kwayo i2000KVar, uye frequency yekushandisa ndeye 1000Hz.
