開閉装置。 A line-side device is connected to one of the outlets of a circuit breaker having at least two outlets, the first and second busbar switching disconnectors are connected horizontally and linearly to the other outlet, and The first and second busbar switching disconnectors are connected to phase-separated type first and second main busbars arranged horizontally below, respectively. The middle phase of the first main bus is arranged directly below the first bus switching disconnect switch, and the end phase of the first main bus is arranged vertically and horizontally, respectively. The middle phase of the second main busbar is arranged diagonally above the middle phase that does not overlap with the phase either laterally or in plan, and the middle phase of the second main busbar is arranged laterally at approximately the same height as the end phase of the first main busbar. The end phase of the second main bus bar is arranged so as to overlap with the second main bus bar.
A gas insulated switchgear which is arranged obliquely above the middle phase of the main bus bar, one end phase of which is located above one end phase of the first main bus bar so that they do not overlap in plane. .
