Momwe mungasankhire thyristor kwa ng’anjo yosungunuka?

Mu mphamvu yokonza ndondomeko ya chowotcha kutentha, momwe mungasankhire yoyenera inverter thyristor malinga ndi ntchito yeniyeni ingatsatire mfundo zotsatirazi:

1. Sankhani nthawi yopuma molingana ndi kuchuluka kwa ntchito yamagetsi osungunula ng’anjo:

a) Thyristor yamtundu wa KK yokhala ndi nthawi yosankhidwa ya 20µs-45µs pafupipafupi 100HZ—500HZ.

b) Thyristor yamtundu wa KK yokhala ndi nthawi yosankhidwa ya 18µs-25µs pafupipafupi 500HZ—1000HZ.

c) Thyristor yamtundu wa KK yokhala ndi ma frequency a 1000HZ—2500HZ ndi nthawi yosankhidwa ya 12µs-18µs.

d) KKG lembani thyristor yokhala ndi nthawi yosankhidwa ya 10µs-14µs pafupipafupi 2500Hz—4000Hz.

e) thyristor yamtundu wa KA yokhala ndi mafupipafupi a 4000HZ—8000HZ ndi nthawi yozimitsa yosankhidwa ya 6µs–9µs.

2. Sankhani voliyumu yoyimilira ndikuvotera panopa malinga ndi mphamvu ya ng’anjo yosungunula induction:

Malinga ndi mawerengedwe ongoyerekeza a parallel mlatho inverter dera la induction kusungunula ng’anjo, panopa kuyenda mu induction iliyonse kusungunula ng’anjo thyristor ndi 0.455 nthawi zonse panopa. Poganizira kuti pali malire okwanira, kukula kofanana ndi komweku komweko kumasankhidwa nthawi zambiri. thyristor.

a) Thyristor yokhala ndi magetsi osankhidwa a 300A/1400V okhala ndi mphamvu ya 50KW—-100KW. (380V patsogolo voteji)

b) SCR yokhala ndi mphamvu yosankhidwa ya 500A/1400V yokhala ndi mphamvu ya 100KW—250KW. (380V patsogolo voteji)

c) SCR yokhala ndi 800A/1600V yosankhidwa ndi mphamvu ya 350KW-400KW. (380V patsogolo voteji)

d) SCR yokhala ndi 1500A/1600V yosankhidwa ndi mphamvu ya 500KW-750KW. (380V patsogolo voteji)

e) SCR yokhala ndi magetsi osankhidwa a 1500A/2500V okhala ndi mphamvu ya 800KW-1000KW. (660V patsogolo voteji)

f) SCR yokhala ndi 2000A/2500V yosankhidwa ndi mphamvu ya 1200KW-1600KW. (660V patsogolo voteji)

g) SCR ya osankhidwa panopa 2500A/3000V ndi mphamvu ya 1800KW-2500KW. (1250V gawo-in voteji)
