Abstract:
A polarity-independent switching device for carrying and disconnecting high DC currents has a gastight, encapsulated, electrically insulating housing which can be filled with an insulating gas, and at least one pair of contacts disposed in the housing and made up of a fixed contact and a mobile contact. The two contacts are in contact with each other in a switched-on state of the switching device and are not in contact in a switch-off state of the switching device. An arc driver arrangement is included which generates a magnetic field at least in the region of the pair of contacts, as well as a first arc routing arrangement with which an arc produced between the contacts is guided in a first current direction to a quenching area arranged at a distance from the contacts.
