ABSTRACT:
The switchgear assembly has a polyphase design and has a gas-filled, modular encapsulation for each phase. Provided as the modules are at least one busbar, which is guided predominantly horizontally, a circuit breaker and two combined disconnecting-earthing switches having a disconnection and grounding function. A first one of the combined disconnecting-earthing switches supports a section of the busbar and is connected between the busbar and a first current terminal of the circuit breaker. The second combined disconnecting-earthing switch is connected between an outgoing feeder or a further busbar of the assembly and the second current terminal of the circuit breaker. The combined disconnecting-earthing switches are aligned such that two drive apparatuses, which are provided for their actuation, point in the same, predominantly horizontal direction.
