Ungakhetha kanjani i-inverter thyristor yesithando somlilo se-induction?
Ungakhetha kanjani i-inverter thyristor yesithando somlilo se-induction?
1) Khetha ngokuya ngobubanzi bemvamisa yokusebenza yesithando somlilo sokuncibilika;
Isikhathi esikhethiwe sokuvala imvamisa ngu-100HZ—500HZ ingu-20µs-45µs KK uhlobo lwe-thyristor.
Imvamisa ngu-500HZ—1000HZ, isikhathi sokuvala esikhethiwe ngu-18μs-25μs KK uhlobo lwe-thyristor.
I-thyristor yohlobo lwe-KK imvamisa yayo ingu-1000HZ—2500HZ futhi isikhathi sokuvala esikhethiwe ngu-12μs-18μs.
I-KKG yohlobo lwe-SCR enefrikhwensi ephakathi kuka-2500HZ—4000HZ futhi isikhathi sokuvala esikhethiwe ngu-10µs-14µs.
I-KA-type thyristor imvamisa yayo iphakathi kuka-4000HZ—8000HZ futhi isikhathi sokuvala esikhethiwe siphakathi kuka-6μs no-9μs.
2) Khetha ngokusho kwamandla okukhipha isithando somlilo sokuncibilika;
Ngokwezibalo zetiyetha zesekethe ye-inverter yebhuloho elihambisanayo, okwamanje okugeleza ku-thyristor ngayinye izikhathi eziphindwe kabili kunamanje. Uma kucatshangelwa ukuthi kunomkhawulo okwanele, i-thyristor enobukhulu obufanayo nesilinganiso samanje sivame ukukhethwa.
I-thyristor yamanje ekhethiwe engu-300A/1400V enamandla angu-50KW—-100KW. (380V isigaba-in voltage)
I-thyristor yamanje ekhethiwe engu-500A/1400V enamandla asuka ku-100KW kuya ku-250KW. (380V isigaba-in voltage)
I-thyristor yamanje ekhethiwe engu-800A/1600V enamandla asuka ku-350KW ukuya ku-400KW. (380V isigaba-in voltage)
I-thyristor yamanje ekhethiwe engu-1500A/1600V enamandla aphakathi kuka-500KW no-750KW. (380V isigaba-in voltage)
I-thyristor yamanje ekhethiwe engu-1500A/2500V enamandla angu-800KW-1000KW. (660V isigaba-in voltage)
I-thyristor yamanje ekhethiwe engu-2000A/2500V enamandla angu-1200KW-1600KW. (660V isigaba-in voltage)
I-thyristor yamanje ekhethiwe engu-2500A/3000V enamandla aphakathi kuka-1800KW no-2500KW. (1250V isigaba-in voltage)
