Abstract
A gas insulated switchgear is configured including phase-A, phase-B, and phase-C breaker units. For example, the phase-A breaker unit includes breakers connected in series in a horizontal first direction, disconnectors annexed on the breaker, disconnectors annexed on a breaker, and disconnectors annexed on a breaker. The disconnector is connected to a main bus that extends in the first direction, and the disconnector is connected to a main bus that extends in the first direction. Each of the disconnectors on the breakers is arranged while a longitudinal direction thereof is set to a second direction orthogonal to the first direction so that a switching direction of the disconnector is equal to the second direction. Thereby, the length of the main buses can be shortened, and an interphase distance and a breaker-to-breaker distance can be reduced.
