| description | The utility model relates to a breaker arc extinguishing mechanism which takes sulfur hexafluoride as the insulation and arc extinguishing media; the sulfur hexafluoride breaker arc extinguishing mechanism includes an arc extinguishing cover, a connection screw, an insulator which is arranged between the arc extinguishing cover and the connection screw, a resin shell body and an arc extinguishing coil in the shell body; a movable contact drills through the arc extinguishing cover to electrically connect with a static contact finger switch of the connection screw for cooperation of the connection; an arc extinguishing chamber seal cover is arranged in the arc extinguishing cover; the movable contact is drilled through from an axial through hole which is arranged in the center of the seal cover; between the two a gas flow gap is arranged. The utility model integrates the rotating arc and self-extinguish arc extinguishing mechanisms organically, thus to realize the technical aim of normal breaking of the larger breaking current, in addition, the utility model has high work reliability and simple structure. |
