Abstract
The present invention relates to a self-cooled thyistor device for ultra-high voltage fault current limiter. a self-cooled thyristor valve, it adopts horizontal structure consisted by frames, frames is divided into upper and below two spaces by crossbeams, the bottom of frames is supported by insulators. There is a cross plate between two vertical said frames, the cross plate mounts resistors connect with a high potential plate and capacitor through two wires. There is a thyistor string in said frame upper space, which is constituted of thyistors and cooler series. The thyistor string is compressed tightly by press-fit mechanism, thyistor string crosses current transformers. There are high potential plates on both sides of the thyistor, the number of the potential plates is equal to that of thyistor. One side of the high potential plates links frames, said current transformers connects with high potential plates. There are capacitors and resistors connected with the bottom plate of said frames in the below space. The small and well-structured invention meets the requirement of the energy on continuous trigger condition, improves the global reliability of thyristor valve.
