要約(英語): Differences between domestic standard JEM and foreign national standards ANSI, GB for medium-voltage switchgear were investigated and summarized in this study. Medium-voltage switchgear for rated voltage above 1kV and up to and including 84kV has been widely applied to electric power company, general industry, and electric railway over 50 years. Main circuit insulation is mainly air insulation type. Recently, SF6 gas, solid, or vacuum insulation types were developed. Interruption media of circuit breaker were changed from air or oil to vacuum. Applications of medium-voltage switchgear were expanded to ships, on/off-shore renewable energy plants. In this paper, recent technology trends were reviewed for corresponding to special specifications and results of performed questioner survey were shown for domestic application of medium-voltage switchgear in Japan.
