Claims

[Scope of Claim for Utility Model Registration] (1) Switching device components such as circuit breakers, disconnectors, and earthing switches are housed in an outer shell container filled with an insulating gas, and a frame that supports the outer shell container. In the cubicle-type gas-insulated switchgear in which a circuit breaker operator, a disconnector operator, and a grounding switch operator are arranged, there is provided an integrated mechanism case having a mechanism storage chamber communicating with the interior of the outer shell container. disposed within the pedestal, the one-piece mechanism case is fixed between the bottom plate of the outer shell container and the bottom of the pedestal so as to serve as a reinforcing structural member that supports part of the load of the outer shell container; A disconnector operating device and an earthing switch operating device are attached to the outside of the integrated mechanism case, and the operating force outputted by the disconnecting switch operating device and the earthing switch operating device is transmitted to the disconnecting switch and the earthing switch. A cubicle type gas insulated switchgear, characterized in that a part of the operating force transmission mechanism is disposed within the mechanism housing chamber. (2) The opening/closing device components are disposed in one gas space formed within the outer shell container, the mechanism case is formed in a box shape with one end open, and the one end is connected to the outer shell container. The cubicle type gas insulated switchgear according to claim 1, wherein the cubicle type gas insulated switchgear is connected by welding to a peripheral part of an opening formed in the bottom plate, and the other end of the mechanism case is fixed to the bottom part of the pedestal via a mounting means. . (3) The disconnector operating device and the grounding switch operating device are attached to one side wall of the mechanism case,
2. The cubicle-type gas insulated switchgear according to claim 1, wherein the other side wall opposite to the one side wall is provided with a window, and the window is hermetically closed by a removable lid member.
