Sidee loo doortaa inverter thyristor foornada dhalaalka induction?
Sidee loo doortaa inverter thyristor foornada dhalaalka induction?
1) Dooro iyadoo loo eegayo kala duwanaanta soo noqnoqda hawlgalka ee foornada dhalaalidda induction;
Waqtiga la doortay ee daminta inta jeer waa 100HZ-500HZ waa 20µs-45µs KK nooca thyristor.
Inta jeer waa 500HZ-1000HZ, wakhtiga daminta la doortay waa 18μs-25μs KK nooca thyristor.
KK-nooca thyristor oo soo noqnoqda waa 1000HZ-2500HZ iyo wakhtiga daminta la doortay waa 12μs-18μs.
Nooca KKG SCR oo leh inta u dhaxaysa 2500HZ-4000HZ iyo wakhtiga daminta la doortay waa 10µs-14µs.
Ka-nooca thyristor oo soo noqnoqda u dhexeeya 4000HZ-8000HZ iyo wakhtiga daminta la doortay waa inta u dhaxaysa 6μs iyo 9μs.
2) Dooro iyadoo loo eegayo awoodda wax soo saarka foornada dhalaalka induction;
Marka loo eego xisaabinta aragtida ee wareegga isbarbardhigga buundada, hadda socodka dhex mara thyristor kasta waa jeer wadarta hadda. Iyadoo la tixgelinayo in uu jiro margin ku filan, thyristor leh cabbir la mid ah kan hadda la qiimeeyay ayaa badanaa la doortaa.
Thyristor 300A/1400V ee hadda la doortay oo leh awood 50KW—-100KW. (380V wejiga ku jira tamarta)
Thyristor 500A/1400V ee hadda la doortay oo leh awood 100KW ilaa 250KW (380V wejiga ku jira tamarta)
Thyristor 800A/1600V ee hadda la doortay oo leh awood u dhaxaysa 350KW ilaa 400KW. (380V wejiga ku jira tamarta)
Thyristor 1500A/1600V ee hadda la doortay oo leh awood u dhaxaysa 500KW iyo 750KW. (380V wejiga ku jira tamarta)
Thyristor 1500A/2500V ee hadda la doortay oo leh awood 800KW-1000KW (660V wejiga ku jira tamarta)
Thyristor 2000A/2500V ee hadda la doortay oo leh awood 1200KW-1600KW (660V wejiga ku jira tamarta)
Thyristor 2500A/3000V ee hadda la doortay oo leh awood u dhaxaysa 1800KW iyo 2500KW. (1250V wejiga ku jira tamarta)
