Abstract: Adapter (300) adapted to connect a gas source (100) to a gas-insulated switchgear (500), gas supply system (10) for a gas-insulated switchgear (500), and gas-insulated switchgear. The gas supply system (10) comprises: a gas source (100), an adapter (300), an inlet valve (200) connected to the gas source (100) and connectable to the adapter (300), and an outlet valve (400) connectable to the gas-insulated switchgear (500) and the adapter (300), wherein
the inlet valve (200) is adapted to open and/or close a first fluid connection (310) between the adapter (300) and the gas source (100),
the outlet valve (400) is adapted to open and/or close a second fluid connection (312) between the adapter (300) and the gas-insulated switchgear (500), and
the adapter (300) is configured to receive the inlet valve (200) and the outlet valve (400) so as to establish the first and second fluid connections (310, 312),
wherein
in a state where the inlet valve (200) is inserted into the adapter (300) to a penetration depth less than a first penetration depth (L1), the inlet valve (200) and the outlet valve (400) are adapted to close the first and second fluid connections (310, 312),
in a state where the inlet valve (200) is inserted into the adapter (300) to a penetration depth greater than a second penetration depth (L2), which is greater than the first penetration depth (L1), the inlet valve (200) and the outlet valve (400) are adapted to open the first and second fluid connections (310, 312), and
the first and second fluid connections (310, 312) are gas-tight with respect to the environment.
