Mabda’a shaqada iyo shaqada ugu weyn ee thyristor

1. Mabda’a shaqada ee thyristor waa:

1. Si thyristor -ka loo shido, mid waa in la adeegsadaa danab hore oo u dhexeeya anode A iyo cathode K, kan kalena waa in la geliyo danab kiciya togan oo u dhexeeya korantada koontaroolka G iyo cathode K. Ka dib marka thyristor -ka la shido, sii daayo badhanka badhanka, ka saar danab kiciyaha, oo wali ilaali xaaladda.

2. Si kastaba ha ahaatee, haddii danab gadaal loo mariyo anode ama koontaroolka korontada, thyristor -ka lama furi karo. Shaqada tiirka koontaroolka ayaa ah in la shido thyristor -ka iyadoo la adeegsanayo garaaca garaaca wadnaha, laakiin lama damin karo. Damiinta thyristor -ka ayaa jari kara korontada anode (beddel S ee Jaantuska 3) ama ka dhigi kara anode hadda mid ka yar qiimaha ugu yar ee lagu ilaalinayo habsami u socodka (oo loo yaqaanno joogtaynta hadda jirta). Haddii danab AC ah ama danab garaacaya DC la mariyo inta u dhexeysa anode iyo kaatoodhka thyristor, thyristor -gu iskiis ayuu damin doonaa marka danabku eber dhaafo.

2. Hawlaha thyristor ee wareegga waa sida soo socota:

1. Beddel/hagaajiye.

2. Cadaadiska hagaaji.

3. Beddelidda inta jeer.

4. Beddel.

Mid ka mid ah shaqooyinka ugu muhiimsan ee SCR waa xasilinta hadda. Thyristors -ka ayaa si weyn loogu adeegsadaa koontaroolka otomaatiga ah, beeraha korontada, korontada warshadaha iyo qalabka guryaha. Thyristor -ku waa cunsur beddela oo firfircoon. Sida caadiga ah waxaa lagu hayaa xaalad aan dhaafin ilaa ay ka kiciso signalada kontoroolka oo yar ama “la shido” si ay uga gudubto. Mar haddii la shido, way sii jiri doontaa xitaa haddii calaamadda kicinta la laabo. Xaaladda kanaalka, si loo gooyo, danab gadaal ayaa lagu dabaqi karaa inta u dhexeysa anode iyo cathode ama kan hadda maraya thyristor diode ayaa hoos loogu dhigi karaa qiimo go’an.
