Zusammenfassung:	A gas-insulated switching apparatus (101) of a three-phase-isolated type includes: two first main buses (11a) and (21a) extending in parallel at an identical height; a first connection bus (31a) interconnecting the first main buses (11a) and (21a); a first divergence bus (41a) diverging downward from the first connection bus (31a); and a first circuit breaker (53) connected to the first divergence bus (41a), wherein a connection portion (60) between the first connection bus (31a) and the first divergence bus (41a) is disposed at a position lower than the height at which the first main buses (11a) and (21a) extend, and a grounding switch (52a) is disposed above the connection portion (60) between the first connection bus (31a) and the first divergence bus (41a).
