という問題があった。[Problems to be Solved by the Invention] For example, when the switchgear component is housed in the outer shell container 2 in which SF6 gas is sealed, the total weight of the outer shell container 2 reaches several tons. Therefore, the cradle 1 is a very heavy outer shell container 2
It is required to have sufficient strength to support the.
Therefore, in order to reinforce the gantry 1, it has been proposed to dispose reinforcing beams inside the gantry 1. However, in the conventional cubicle type insulated switchgear, the mechanism case (1
0, 12, 15, 17), when the beam is actually provided, the beam interferes with the assembly, repair and operation of the plurality of operating devices. Therefore, conventionally, in order to obtain the strength required for the gantry 1, a thick pillar member or a thick wall member has been used as a pillar member and a wall member forming the gantry. Therefore, the gantry used in the conventional device has a problem that the weight is heavy and the manufacturing cost is high.

形且つ安価に製造することができる。[Operation] Conventionally, the overall strength of the gantry has been increased by increasing the strength of the members constituting the gantry. However, the inventor used a mechanical case arranged inside the gantry to improve the strength of the gantry. I thought to increase. Even when the mechanical case is used to reinforce the gantry, workability and economic efficiency deteriorate if the interior of the gantry becomes complicated or the gantry becomes large in size. Therefore, in the present invention, a collective type mechanical case is used for each of the disconnecting switch operating device and the grounding switch operating device. The collective type mechanical case has a considerably large size because it houses a part of the operating force transmission mechanism of each operating device. By fixing this large package type mechanical case between the bottom plate of the outer shell container and the bottom of the gantry, the mechanism case becomes a reinforcing structural member that supports a part of the load of the outer shell container. When the collective mechanism case is used as the reinforcing structure member in this way, a member which is lighter and cheaper than the conventional member can be used as a member (a pillar member, a wall member, etc.) constituting the gantry. Therefore, according to the present invention, the weight of the gantry can be made lighter than before, and the gantry can be manufactured in a small size and at a low cost.
