(5.)Scientific Research

          

           Prof. Dr. Zhiyuan Liu is one of the major contributors in the research field in transmission voltage level vacuum circuit breaker in China. His team developed the first 126kV/2500A/40kA single-break vacuum circuit breaker in China, which passed type test in 2013. The contribution is toward to reduce SF6 gas usage in high voltage switchgear. SF6 gas is a strong global warming effect gas pointed by Kyoto protocol. In the field of transmission voltage level vacuum circuit breaker, he held 128 Chinese patents and 2 US patents. He published 520 technical papers, mainly in the field of vacuum circuit breaker, including vacuum arc, vacuum insulation, operating mechanism ect.
