The technological advancement for larger capacities of vacuum circuit breakers in recent years has truly been prominent. Based on data of a series of in-house tests made so far and on performance in the field, Toshiba Corporation has developed a metal-clad switchgear with vacuum circuit breakers for nuclear power plants. Metal-clad switchgears for nuclear power plants are strongly required to have high reliability and large capacities. This paper describes results of a series of reliability tests made on the vacuum circuit breaker and resistance to earthquakes of the metal-clad switchgear required for use in a nuclear power plant.
