Litekanyetso tsa khetho ea Thyristor bakeng sa 1000kw ho qhibiliha ha sebōpi

Mohala o hlophisitsoeng oa mohala o kenang ke 380V, ‘me lintlha tse latelang li ka fumanoa ka lipalo:

DC voltage Ud=1.35×380V=510V

DC jwale Id=1000000÷510=1960A

Maqhubu a mahareng a maqhubu Us=1.5×Ud =765V

Rectifier ea silicon e lekantsoe hajoale IKP=0.38×Id=745A

E lekantsoe matla a ho lokisa silicon UV=1.414×UL=1.414×510V=721V

Inverter silicon rated hajwale Ikk=0.45×19600=882A

Inverter silicon rated voltage UV=1.414×Us=1082V

Leano la khetho ea mohlala oa SCR: khetha Xiangfan Taiji SCR:

Hobane e amohela tlhahiso ea 6-pulse single rectifier, SCR ea rectifier e khetha KP2000A/1400V (kakaretso ea 6), ke hore, ea hajoale e lekantsoeng ke 2000A mme motlakase o lekantsoeng ke 1400V. Ha ho bapisoa le boleng ba theory, margin ea voltage ke makhetlo a 1.94 ‘me moeli oa hona joale ke makhetlo a 2.68.

Inverter thyristor e khetha KK2500A / 1600V (tse ‘nè ka kakaretso), ke hore, hona joale e lekantsoeng ke 2500A,’ me motlakase o lekantsoeng ke 1600V. Ha ho bapisoa le boleng ba theory, margin ea voltage ke makhetlo a 1.48, ‘me moeli oa hona joale ke makhetlo a 2.83.
