Sidee loo doortaa thyristor foornada dhalaalka induction?
Sidee loo doortaa thyristor foornada dhalaalka induction?
Habka naqshadaynta awoodda ee foornada dhalinta dhalaalaysa, sida loo doorto thyristor inverter ku habboon si waafaqsan codsiga dhabta ah waxay raaci kartaa mabaadi’da soo socota:
1. Dooro wakhtiga fasaxa iyadoo loo eegayo inta jeer ee shaqada ee sahayda foornada dhalaalaysa ee induction:
a) Thyristor-nooca KK oo leh wakhti ka baxsan oo la doortay 20µs-45µs inta jeer ee 100HZ-500HZ.
b)Tyristor-nooca KK oo leh wakhti-ka-foono oo la doortay 18µs-25µs oo ah inta jeer ee 500HZ-1000HZ.
c)Tyristor-nooca KK oo leh inta jeer ee 1000HZ-2500HZ iyo wakhti-daaqsanaan la doortay oo ah 12µs-18µs.
d) Nooca KKG thyristor oo leh waqti-ka-baxsan oo la doortay 10µs-14µs inta jeer ee 2500Hz—4000Hz.
e) nooca KA-thyristor oo leh inta jeer ee 4000HZ-8000HZ iyo wakhtiga daminta ee la doortay ee 6µs–9µs.
2. Dooro danabka adkeysiga iyo hadda la qiimeeyay iyadoo loo eegayo tamarta foornada dhalaalaysa ee induction:
Marka loo eego xisaabinta aragtida ee wareegga isbarbardhigga buundada isbarbardhigga foornada dhalaalka induction, hadda qulqulaya mid kasta oo foornada dhalaalaysa ee thyristor waa 0.455 jeer wadarta hadda. Iyadoo la tixgelinayo in ay jirto margin ku filan, cabbir la mid ah kan hadda la qiimeeyay ayaa badanaa la doortaa. thyristor.
a) Thyristor leh hadda la doortay oo ah 300A/1400V oo leh awood 50KW—-100KW. (380V danab hore)
b) SCR oo leh hadda la doortay oo ah 500A/1400V oo leh awood 100KW—250KW. (380V danab hore)
c) SCR oo leh hadda la doortay oo ah 800A/1600V oo leh awood 350KW–400KW. (380V danab hore)
d) SCR oo leh hadda la doortay oo ah 1500A/1600V oo leh awood 500KW–750KW. (380V danab hore)
e) SCR oo leh hadda la doortay oo ah 1500A/2500V oo leh awood 800KW-1000KW ah. (660V danab hore)
f) SCR oo hadda la doortay oo ah 2000A/2500V oo leh awood 1200KW-1600KW. (660V danab hore)
g) SCR ee hadda la doortay 2500A/3000 oo leh awood 1800KW-2500KW. (1250V wejiga ku jira tamarta)
