Patent ID: 8149577

Claim:
A self-cooled thyristor device, comprising: a horizontal structure comprising vertical frames ( 1 ), wherein said frames are divided into upper and lower spaces by a crossbeam ( 2 ), and wherein said frames are supported by insulators ( 13 ); a cross plate ( 3 ) between said frames ( 1 ), wherein said cross plate ( 3 ) mounts a resistor ( 4 ), and wherein said resistor ( 4 ) connects with a high potential plate ( 8 ) and a capacitor ( 9 ) through two wires; a thyristor string ( 6 ) in said frame upper space, said thyristor string ( 6 ) comprising thyristors ( 61 ), and connecting with a cooler ( 62 ) thyristor-by-thyristor, wherein said thyristor string ( 6 ) is compressed tightly at two extremities by a press-fit mechanism ( 5 ), and said thyristor string crosses current transformers ( 7 ); one or more high potential plates ( 8 ) on both sides of said thyristors ( 61 ), wherein the number of said potential plates ( 8 ) is equal to that of said thyristors ( 61 ), and wherein one side of the high potential plates ( 8 ) links the frames ( 1 ), and said current transformers ( 7 ) connects with high potential plates ( 8 ); one or more capacitors ( 9 ) connected with the bottom plate of said frames ( 1 ) in the lower space; one or more and resistors ( 10 ) connected with the bottom plate of said frames ( 1 ) in the lower space; one or more optical fibers troughs ( 11 ) fixed at the upper space of said frames ( 1 ).
