A coupling switching arrangement for longitudinal coupling, cross-coupling and transverse coupling of double busbar systems in electrical switching devices has, as an isolating switch, a combination of two single- and two three-stage switches whose rotation point contacts are connected to one another via a circuit breaker and, in the presence of a back-up supply, additionally two two-stage switches which are connected with their rotation point contacts and one of their two isolating point contacts into the isolated connecting line between the isolating point contacts of the two three-stage switches and the busbar line respectively allocated thereto, and their other isolating point contacts are connected to one another and the back-up current source. <IMAGE> |
