Abstract
An indoor switchgear or controlgear arrangement with unmanned operation and maintenance, for use in low, medium, or high voltage, includes: an arrangement of switching devices in an inner housing, which is furthermore provided with an outer housing; and a robot system, acting mainly in the inner housing. At least the switching devices other than maintenance critical parts are withdrawable. The switchgear or controlgear is provided with interlocks in order to prevent a wrong sequence of operation and prevent access to potentially hazardeous compartments. Metallic segregation is provided internally in the inner housing in order to achieve a needed service continuty level.
