摘要： A switch unit for a voltage circuit breaker comprising a first switch contact 202a; a second switch contact 202b is movable between first position and a second position, wherein the second switch contact is separated from the first switch contact; a positioning element to position an arc chute 100 on the switch unit 200, wherein the arc chute 100 comprises a plurality of substantially parallel metal plates 104, 104a, 104b,
… , 104n, 108, 108a, 108b,
… , 108n, the positioning element being arranged such that an arc, which is created between the first switch contact 202a and the second switch contact 202b, is guided into the arc chute in an arc displacement direction A in order to be extinguished; and at least one gas emitting element 220a, 220b comprising a gas emitting layer having a layer surface 221a, 221b facing the first switch contact and the second switch contact. The gas emitting element is arranged at a distance to the first switch contact and the second switch contact, such that at an interruption operation of the circuit breaker at its nominal current an arc between the first switch contact and the second switch contact vaporizes a portion of the gas emitting layer.

摘要： An arrangement in an electrical switching device for protection against electrical arcs comprises a tripping mechanism, a stationary contact carrier, a movable contact carrier, an exhaust vent, an arc runner, and an arc extinguishing barrier. The stationary contact carrier has a stationary contact mounted thereon, and the movable contact carrier has a movable contact mounted thereon. In response to an overcurrent condition, the tripping mechanism causes the movable contact carrier to rotate from a closed position to an open position, thereby generating an electrical arc. In the closed position the movable contact abuts the stationary contact, and in the open position the movable contact is separated from the stationary contact. The arc extinguishing barrier is composed of an outgassing material and is located between the stationary contact and a portion of the tripping mechanism. The stationary contact is located generally between the portion of the tripping mechanism and the arc runner such that the arc runner draws the electrical arc away from the portion of the tripping mechanism. The exhaust vent is located generally in line with the initial direction of movement of the movable contact when the movable contact carrier begins rotating from the closed position to the open position.

摘要： Es wird eine Flachlöschkammer 36 für einen Lasttrennschalter 10 mit schwenkbar gelagertem Schleppmesser 30 beschrieben. Diese besteht aus einem einen Schleppmesserkontakt 38 aufnehmenden Flachgehäuse, das seitliche Löschplatten 42 umfaßt, die aus Löschgas abgebendem Material bestehen und zwischen sich einen Löschspalt definieren. Der Löschspalt ist durch einen sich über einen Schleppmesserschwenkbereich erstreckenden, in der Schwenkebene des Schleppmessers 30 betrachtet schmalen Löschkanal 34 gebildet, wobei die Löschplatten 42 vorzugsweise durch mehrere, insbesondere entlang des schmalen Löschkanals 34 vorgesehene Verbindungselemente 52 so abgestützt und/oder fixiert sind, daß der Querschnitt des Löschkanals 34 unabhängig von dem jeweiligen Abschaltstrom und dem jeweiligen Gasdruck in dem Flachgehäuse zumindest im wesentlichen gleich bleibt.

摘要： A switch comprising a switch case, contacts adapted to be opened and closed, an arc extinguishing chamber disposed in the vicinity of the contacts, and an arc extinguishing material capable of reducing the amount of metal particles and free carbons to be scattered from components disposed within the switch by an arc generated when the contacts are opened or closed or capable of insulating the metal particles and the free carbons to convert into an insulator, thereby inhibiting a decrease in arc resistance expected to occur upon the generation and extinction of the arc and a decrease in insulation resistance expected to occur within and around the arc extinguishing chamber and at inner wall surfaces of the switch case upon and after the extinction of the arc. The switch according to the present invention is applicable to a switch expected to generate an arc upon interruption of electric current flowing therethrough such as a circuit breaker, current-limiting device or electromagnetic contactor and is capable of immediately extinguishing the arc and inhibiting the decrease in insulation resistance within and around the arc extinguishing chamber and at inner wall surfaces of the switch case.

摘要： This invention relates to an arc chamber (10) constituted by shaped blades (11) made of metal material. Such blades are positioned side by side to, in a sub parallel arrangement and are joined with one another by means (12) of a non-conductive material. One of said metal blades is in contact with an element made of an organic-based material, capable of releasing a gas when it is struck by the electric arc.
