要約(英語): The high-voltage switchgear is installed in the electric power system to realize a stable electric supply. SF6 gas insulation enabled the switchgear to be compact, and its economics and reliability have been improved. Recently, as actions to prevent climate change and realize the sustainable society, reduction of environmental burdens and increase of renewable energy resources are major issue even on the high-voltage switchgear. For prevention of climate change, Alternative technology for SF6 which is one of the global warming gases is vigorously being developed. Vacuum circuit breaker is one of the solutions and technology of vacuum insulation and interruption for high voltage level are introduced. However, extra-high-voltage level, still some breakthroughs are desired and seven requirements for SF6 alternative technology are proposed from a working group in Japan. Moreover, for large penetration of renewable energy, the high-voltage direct-current circuit breakers are developing globally. Verification tests are in progress for proposed pure mechanical type dc circuit breaker with vacuum interrupting technology and hybrid type one with solid-state and mechanical switches.
