<p>PURPOSE:To reduce the installation area for a gas-insulated switchgear in which a switchgear for bus sections device between double bus-bar devices in a connectable state. CONSTITUTION:The title gas-insulated switchgear is composed of a first switchgear 11 for bus sections which divides first and third main bus-bars 1 and 3 in a connectable state, and a second switchgear 12 for bus sections which divides second and fourth main bus-bars 2 and 4 in a connectable state, and the first and fourth main bus-bars 1 and 4 are arranged on a first horizontal plane. And the second main bus-bar 2 penetrates the first switchgear 11 for bus sections, and is arranged on a second horizontal plane higher than the first one. And the third main bus-bar 3 is arranged on a third horizontal plane higher than the second one at a part where the second switchgear 12 for bus sections is arranged, and arranged falling up to the second horizontal plane at a part where the second switchgear 12 for bus-bars is got over.</p> |
