The aim of the invention is to provide a switch arrangement (1) of a d.c. voltage network having a plurality of d.c. voltage switches, which are each disposed in different branches (12, 13, 14, 15) of the d.c. voltage network and in the event of a fault are configured for isolating the faulty branch (12, 13, 14, 15) of the d.c. voltage network, wherein one of the d.c. voltage switches is a d.c. voltage power switch (7, 8, 17) which is configured for quickly switching off fault currents, wherein the energy flow can be quickly restored and at the same time the switch arrangement remains cost-effective. In order to achieve said aim, at least one second d.c. voltage switch is a d.c. voltage load switch (6, 9, 10, 11) which is configured for quickly switching off rated currents which are lower than the fault currents. |
