Kodi mungasankhire bwanji inverter thyristor pa ng’anjo yosungunuka?
How to choose inverter thyristor for ng’anjo yosungunula induction?
1) Sankhani molingana ndi kuchuluka kwa magwiridwe antchito a ng’anjo yosungunuka;
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) Sankhani molingana ndi mphamvu yotulutsa ng’anjo yosungunula induction;
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.
The osankhidwa panopa 300A/1400V thyristor ndi mphamvu pakati 50KW ndi 100KW. (380V gawo-in voteji)
The osankhidwa panopa 500A/1400V thyristor ndi mphamvu ya 100KW-250KW. (Voliti ya 380V gawo-in)
The osankhidwa panopa 800A/1600V thyristor ndi mphamvu kuyambira 350KW kuti 400KW. (380V gawo-in voteji)
The osankhidwa panopa 1500A/1600V thyristor ndi mphamvu pakati 500KW ndi 750KW. (380V gawo-in voteji)
The osankhidwa panopa 1500A/2500V thyristor ndi mphamvu pakati 800KW ndi 1000KW. (660V gawo-in voteji)
The osankhidwa panopa 2000A/2500V thyristor ndi mphamvu ya 1200KW-1600KW. (Voliti ya 660V gawo-in)
The osankhidwa panopa 2500A/3000V thyristor ndi mphamvu pakati 1800KW ndi 2500KW. (1250V gawo-in voteji)
