    摘要: A gas-insulated switchgear is miniaturized and bus-bars connected to bushings are simplified in configuration. A distance L between outer peripheries of a first vacuum interrupter 12 and a second vacuum interrupter 13 is established to be smaller than an external diameter D of the vacuum interrupters 12 to 14, and insulating barriers 28 to 30 are installed between the first vacuum interrupter 12 and the second vacuum interrupter 13, between the first vacuum interrupter 12 and a hermetically sealed container 11, between the second vacuum interrupter 13 and the hermetically sealed container 11, and between the first and second vacuum interrupters 12 and 13 and the third vacuum interrupter 14.
