- Connectable Disconnect the switch 1 Ob with grounding switch above and below the insulating cylinder 17 on each of the fourth module 31 and the fifth module 32.
- a bus bar 25 and a power cable bushing 8b are attached to the surface, each of which connects to a separate circuit. Further, no gas division spacer is interposed between the fourth module 31 and the fifth module 32, and the gas division spacer mounting hole is closed.
- the gas-insulated switchgear of the present invention unnecessary devices are eliminated from the basic type module, only a short-circuit conductor is used to connect between them, and the one whose opening is closed is connected via a gas-divided spacer. Since the required circuit configuration can be obtained, it is possible to easily cope with any circuit configuration, simplifying circuit planning and standardizing modules.
- the gas insulated switchgear in which the main circuit device is housed in a tank insulated with an insulating gas is a tank having almost the same size and shape.
- An insulating frame capable of supporting a circuit breaker including a vacuum valve and a disconnecting switch with a grounding switch are vertically stacked on each other, and at least one of the disconnecting switch and the movable shaft of the vacuum valve is connected to each other. It is characterized by having two switchgear modules. Therefore, a gas-insulated switchgear using a switch module can be obtained in which the sizes and shapes of the tanks of the modules are equal to each other, and which can correspond to several kinds of electric devices to be housed in the modules.
