The disclosure relates to an electrical switching device, e.g., a high-voltage switch, with a mantle-side electrical connection. According to the disclosure, an encapsulated angle disconnector is fitted between the mantle-side electrical connection and the outdoor bushing or an outgoing cable, by means of which angle disconnector the electrical connection is deflected in the disconnector plane, e.g., toward the vertical in the operating position of the switching device. Exemplary embodiments relate, inter alia, to: a horizontal electrical connection and a, 90&#xb0; disconnector; an additional tilting angle (&#x3b2;) of the angle disconnector about the disconnector input axis; a plurality of mantle-side horizontal electrical connections with associated angle disconnectors, which are tilted away from one another.

High-voltage circuit breaker and switch arrangement

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.
