摘要： The present disclosure relates to an arc extinguishing chamber of an electrical circuit breaker, including an arc-forming chamber enclosing a fixed contact and a moving contact, which, at the time of their separation, form an arc between them, said forming chamber communicating with the input of an arc-quenching chamber comprising a stack of separators extending parallel to one another, and including a magnetic release situated on the side of the fixed and moving contacts and a switching horn situated on the opposite side, where the form of the separators varies progressively from one separator to the next, or by groups of identical separators from one group to another, or a mixture of both, in such a way that this form changes from the V having the largest opening surface area to the V having the smallest opening surface area, in the direction from the magnetic release to the switching horn.

摘要： A circuit interrupter having a compact design. According to some implementations, the circuit interrupter includes a conductor from a terminal to a contact having a portion that is angled with respect to the housing sides. This allows a fastener sleeve used to secure the device housing to be positioned closer to the center of mass of the housing, reducing the area of the housing. In some implementations, an arc splitter is provided which includes conductive plates that are angled with respect to the housing sides, allowing the area of the housing to be reduced. In some implementations, a terminal is designed to accommodate a connection without being doubled back, reducing the clearance required for the terminal and the overall area of the circuit interrupter.

摘要： A switching device suitable for DC operation includes at least one pair of contacts having a first contact and a second contact, wherein at least one of the two contacts is mobile and the two contacts are in contact with one another in a switched-on state of the switching device and are not in contact with one another in a switched-off state of the switching device, further having an arc driver arrangement for generating a magnetic field and an arc guiding arrangement for guiding an arc, which is produced between the contacts, to a quenching device. The problem of quenching arcs independently of the current direction in just one individual quenching apparatus in each case is solved with a substantially homogeneous magnetic field which is generated by permanent magnets.

摘要： 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.
