On June 9, 2020, the 535kV DC circuit breaker jointly developed by Tsinghua University and Beijing Power Equipment Group (BPEG) finished the artificial short circuit test successfully. This testing witnessed the domestic innovative DC switching technology and key indicators reached the international leading level.

At the beginning of 2018, our company, Beijing Xinchuang Chunshu Rectifier Co., Ltd. officially began to develop the coupling negative pressure device for 500kV HVDC circuit breaker and purchased related equipment. The coupling negative pressure device for HVDC circuit breaker developed by our company has been successfully applied to the 535kV DC circuit breaker in the converter station of Zhangbei Ruozhi Project, which is the first in China and the leading level in the world.
