| 摘要 |
The present invention relates to a switching device (1) for interrupting a current flowing through a first electric circuit (10) at a current zero-crossing comprising an arc extinguishing chamber having at least two splitters (30, 31) for splitting an arc into partial arcs, wherein the arc is formed upon an interruption and the partial arcs forms a first alternative current path in parallel or series with the current path of the first electric circuit (10), characterized in that the switching device (1) further comprises a second electric circuit (20) including an impedance unit (50) being configured to connect to the at least two splitters (30, 31) such that, upon an interruption, it forms a second alternative current path in parallel with the first alternative current path. |
