    摘要： An arc plate for a circuit breaker arc chute assembly includes first and second portions coupled to opposing sidewalls of the arc chute assembly, first and second ends, and a throat portion between the first and second portions and including an aperture. The aperture extends from the first end toward the second end and includes an end section, an intermediate neck section adjacent the end section, and an interior section adjacent the intermediate neck section and distal from the end section. The end section has a first width and attracts and directs an arc toward the intermediate neck section. The intermediate neck section tapers from the first width of the end section to a second width, further attracting the arc and directing it into the interior section. The interior section includes a taper and turns with respect to the intermediate neck section, in order to attract and retain the arc.

    摘要： A gassing insulator for the arc chute assembly of a circuit breaker includes a number of insulating members. The arc chute assembly includes first and second opposing sidewalls, and arc plates having first and second ends and first and second legs. Each insulating member includes a first side coupled to one of the first and second opposing sidewalls of the arc chute assembly, a second side disposed generally opposite the first side, a first end disposed at or about the first ends of the arc plates, and a second end disposed distal from the first end of the insulating member and extending toward the second ends of the arc plates. The first side of the insulating member overlays at least one of the first and second legs of the arc plates, in order to electrically insulate them. An arc chute assembly and an electrical switching apparatus are also disclosed.

    摘要： A switching device includes a contact system having a movable contact to be moved along a movement direction, a stationary contact and an improved arc quenching device with a configuration for generating a magnetic field formed in a plane perpendicular to the movement direction and an electrode configuration having a first electrode conductively connected to the movable contact and a second electrode conductively connected to the stationary contact. The first electrode and the second electrode are disposed in such a way that an electric field can be generated between the first electrode and the second electrode perpendicularly to the direction of movement and perpendicularly to the magnetic field.

    摘要： The present invention relates to an arc extinguishing chamber of an electrical circuit breaker, comprising an arc-forming chamber enclosing a fixed contact (2) and a moving contact (1), which, at the time of their separation, form an arc between them, said forming chamber communicating with the input of a second so-called arc-quenching chamber comprising a stack of separators (4) extending parallel to one another, this moving contact (1) extending substantially at right angles to the plane of the separators, so as to pull an arc between the contacts upon their separation, the initial direction of which is substantially parallel to said separators, these separators having, on the side of the moving contact, an opening intended to facilitate the insertion of the arc, said circuit breaker comprising a magnetic release situated on the side of the fixed and moving contacts and a switching horn situated on the opposite side.This arc extinguishing chamber is characterized in that the form of the separators (4) 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 (5).
