The invention relates to a power circuit breaker that is suitable for switching electrical voltages. The power circuit breaker according to the invention comprises two main electrodes, to each of which a respective pole of the voltage to be switched can be connected. During the switching process, at least one of said main electrodes follows a switching path. The power circuit breaker is characterized in that secondary electrodes are additionally provided, which protrude into the vicinity of the switching path and are designed and arranged in such a way that arcs can be produced (a) between the main electrodes and the secondary electrodes and (b) between the individual secondary electrodes during the switching process. The power circuit breaker according to the invention can be advantageously used in vehicles and in ultra-high-voltage AC and HVDC (high-voltage direct current) transmission systems and causes arcs to be extinguished as early as possible during the switching process.
A power circuit breaker for switching electrical voltages, having a first electrode, which can be connected to a first pole (A) of the high voltage to be switched, and a second electrode, which can be connected to a second pole (B) of the voltage to be switched, with switching means being provided, which are suitable to move at least one of the electrodes along a switching path depending on the switching state and thereby to move the electrodes toward each other or away from each other, characterized in that at least one secondary electrode is present, which is situated in the vicinity of the switching path.
A power circuit breaker for switching electrical voltages, said power circuit breaker comprising a first electrode which is connected to a first pole of a high voltage that is to be switched, a second electrode which is connected to a second pole of a voltage to be switched, a switching device for moving at least one of the electrodes along a switching path that extends between the electrodes and depending on a switching state, said switching device for moving the electrodes toward each other or away from each other, and at least one secondary electrode which is situated in the vicinity of the switching path.
