<p>A switching network has at least four nodes which can be connected in each case via three interruptable current branches to other ones of the nodes. These nodes can be connected in at least two partial rings. In order to retain the redundancy of such a system in the case of an expansion to more than four nodes with negligible equipment expenditure and, at the same time, little space requirement, the partial rings are constructed in such a manner that they do not have a common node in a preferred embodiment. In this arrangement, each node of a first one of the two partial rings can be connected to a node of a second one of the two partial rings and, conversely, each node of this partial ring can be connected to a node of the first partial ring. The switching network can be advantageously used, in particular, in high-voltage supply systems.</p> |
