Kedu otu esi ahọrọ thyristor inverter maka ọkụ ọkụ induction?
How to choose inverter thyristor for induction ọkụ na-agbaze?
1) Họrọ dị ka usoro ugboro ole na-arụ ọrụ nke ọkụ ọkụ induction;
The frequency is 100HZ—500HZ and the selected turn-off time is 20µs-45µs KK type thyristor.
The frequency is 500HZ—1000HZ and the selected turn-off time is 18μs-25μs KK type thyristor.
The frequency is 1000HZ—2500HZ and the selected turn-off time is 12μs-18μs KK type thyristor.
KKG-type thyristor with a frequency of 2500HZ—4000HZ and a selected turn-off time of 10µs-14µs.
The frequency is 4000HZ—8000HZ, and the selected turn-off time is 6μs—9μs KA type SCR.
2) Họrọ dị ka mmepụta ike nke induction agbaze ọkụ;
According to the theoretical calculation of the parallel bridge inverter circuit, the current flowing through each thyristor is 0.455 times the total current. Considering that enough space is left, a thyristor with the same size as the rated current is usually selected.
