Yadda za a zabi thyristor don induction narkewa?

A cikin tsarin ƙirar wutar lantarki na injin wutar lantarki, yadda za a zabi dace inverter thyristor bisa ga ainihin aikace-aikace iya bi wadannan ka’idoji:

1. Zaɓi lokacin kashewa bisa ga mitar aiki na induction narkewar wutar lantarki:

a) KK-type thyristor tare da zaɓin kashe lokaci na 20µs-45µs a mitar 100HZ-500HZ.

b) KK-type thyristor tare da zaɓin kashe lokaci na 18µs-25µs a mitar 500HZ-1000HZ.

c) KK-nau’in thyristor tare da mitar 1000HZ-2500HZ da zaɓin kashe lokaci na 12µs-18µs.

d) nau’in KKG thyristor tare da zaɓin kashe lokaci na 10µs-14µs a mitar 2500Hz-4000Hz.

e) KA-type thyristor tare da mitar 4000HZ-8000HZ da zaɓin lokacin kashewa na 6µs–9µs.

2. Zaɓi ƙarfin juriya da ƙididdigewa na halin yanzu bisa ga ƙarfin ƙarfin wutar lantarki na induction:

Dangane da lissafin ka’idar daidaitaccen gada inverter da’irar tanderun narkewa, halin yanzu da ke gudana ta kowace induction narkewa tanderu thyristor shine sau 0.455 na yanzu. Idan aka yi la’akari da cewa akwai isassun tazara, girman daidai yake da na halin yanzu ana zaɓin. thyristor.

a) Thyristor mai zaɓaɓɓen halin yanzu na 300A/1400V mai ƙarfin 50KW—-100KW. (380V gaban ƙarfin lantarki)

b) SCR tare da zaɓaɓɓen halin yanzu na 500A/1400V tare da ƙarfin 100KW—250KW. (380V gaban ƙarfin lantarki)

c) SCR tare da zaɓaɓɓen halin yanzu na 800A/1600V tare da ƙarfin 350KW–400KW. (380V gaban ƙarfin lantarki)

d) SCR tare da zaɓaɓɓen halin yanzu na 1500A/1600V tare da ƙarfin 500KW–750KW. (380V gaban ƙarfin lantarki)

e) SCR tare da zaɓaɓɓen halin yanzu na 1500A/2500V tare da ƙarfin 800KW-1000KW. (660V gaban ƙarfin lantarki)

f) SCR tare da zaɓaɓɓen halin yanzu na 2000A/2500V tare da ƙarfin 1200KW-1600KW. (660V gaban ƙarfin lantarki)

g) SCR na zaɓaɓɓen 2500A/3000V na yanzu tare da ƙarfin 1800KW-2500KW. (1250V lokaci-in ƙarfin lantarki)
