| 摘要 |
The invention relates to an electric direct current network (1, 20) for surface and submarine water vessels and for offshore units, comprising at least one direct current source (21), in particular a battery and/or a fuel cell installation, at least one electric consumer (22), e.g. an electric drive motor or a border network, and at least one cut-off device (23) for cutting off the direct current flowing in the network (1). The cut-off device (23) comprises a vacuum switch (24) arranged in the network (1, 20) and a commutation device (25) enabling an electric arc that is produced when the switch (24) is opened to be cut off by the current flowing through the switch (24). The usability of the water vessel, in particular submarine vessels and offshore units, can be increased as the commutation device (25) is embodied in such a manner that electric arcs produced from the switch currents with a different direction can be cut off by said commutation device. |
