Unokukhetha njani inverter thyristor kwiziko lokunyibilikisa induction?
Unokukhetha njani inverter thyristor kwiziko lokunyibilikisa induction?
I-1) Khetha ngokuhambelana noluhlu lwe-frequency yokusebenza kwesithando sokunyibilikisa induction;
Ixesha elikhethiweyo lokucima le-frequency ngu-100HZ—500HZ yi-20µs-45µs KK uhlobo lwe-thyristor.
I-frequency yi-500HZ-1000HZ, ixesha elikhethiweyo lokucima i-18μs-25μs KK uhlobo lwe-thyristor.
I-KK-uhlobo lwe-thyristor oluqhelekileyo luyi-1000HZ-2500HZ kunye nexesha elikhethiweyo lokuvala li-12μs-18μs.
I-KKG yohlobo lwe-SCR ene-frequency phakathi kwe-2500HZ-4000HZ kunye nexesha elikhethiweyo lokucima yi-10µs-14µs.
I-KA-uhlobo lwe-thyristor oluqhelekileyo luphakathi kwe-4000HZ-8000HZ kunye nexesha elikhethiweyo lokuvala liphakathi kwe-6μs kunye ne-9μs.
2) Khetha ngokwamandla emveliso yesithando sokunyibilikisa induction;
Ngokobalo lwethiyori yesekethe ye-inverter yebhulorho ehambelanayo, i-current equkuqelayo kwi-thyristor nganye ngamaxesha akhoyo. Ukuqwalasela ukuba kukho i-margin eyaneleyo, i-thyristor enobungakanani obufanayo nomlinganiselo olinganisiweyo uhlala ukhethwa.
Ekhethiweyo yangoku 300A/1400V thyristor ngamandla 50KW—-100KW. (380V isigaba sombane)
Ekhethiweyo yangoku 500A/1400V thyristor ngamandla ukusuka 100KW ukuya 250KW. (380V isigaba sombane)
Ekhethiweyo yangoku 800A/1600V thyristor ngamandla ukusuka 350KW ukuya 400KW. (380V isigaba sombane)
Ekhethiweyo yangoku 1500A/1600V thyristor ngamandla phakathi 500KW kunye 750KW. (380V isigaba sombane)
Ekhethiweyo yangoku 1500A/2500V thyristor ngamandla 800KW-1000KW. (660V isigaba sombane)
Ekhethiweyo yangoku 2000A/2500V thyristor ngamandla 1200KW-1600KW. (660V isigaba sombane)
Ekhethiweyo yangoku 2500A/3000V thyristor ngamandla phakathi 1800KW kunye 2500KW. (1250V isigaba sombane)
