摘要： A gas-insulated switching apparatus of a three-phase-isolated type includes: two first main buses and extending in parallel at an identical height; a first connection bus interconnecting the first main buses; a first divergence bus diverging downward from the first connection bus; and a first circuit breaker connected to the first divergence bus, wherein a connection portion between the first connection bus and the first divergence bus is disposed at a position lower than the height at which the first main buses extend, and a grounding switch is disposed above the connection portion between the first connection bus and the first divergence bus.
