Definitions
- the invention relates to an arc extinguishing device for a switching device with a fixed and a movable contact point and with an arc chamber surrounding it, which is designed as a package of U-shaped stamped quenching plates, the quenching plates being kept at a distance at their ends facing away from the contact points and are held together to form an assembly.
- a generic arc extinguishing device is disclosed in EP 0 556 109 B1.
- This switching or protective device an arc arises at the opening contact points when the electrical current is switched off.
- This arc causes wear at the contact points, i.e. a contact erosion, and delays the activation of the circuit, since the current continues to flow until the arc extinguishes.
- the electrical switching device is equipped with the arc extinguishing device. This consists of an arc chamber, baffles and various components, which also perform fluidic tasks.
- the arc chamber is here a package of U-shaped die-cut quenching plates, which are arranged in parallel and kept at a distance. Baffles are arranged at the upper and lower ends of the arc chamber, the fixed contact point being connected to the upper baffle.
- the arc extinguishing device described above functions in such a way that an arc arises between the contact parts which are moving away from one another when the contact point is opened. This is due to electromagnetic Forces moved outward in the direction of the arc chamber.
- the arc base points migrate away from the contact points along the baffles electrically connected to the circuit.
- the arc When the arc has reached the quenching plates, it is divided into partial arcs and cooled by the quenching plates, which leads to the extinction of the partial arcs and to the stopping of the current flow.
- the invention is therefore based on the object of improving an arc extinguishing device of the type mentioned above in such a way that even delicate designs of the extinguishing plates can be installed and fixed in a functionally reliable manner without additional expenditure.
- spacing means are provided which keep the legs or feet of the extinguishing plates in the region of the contact points at a distance.
- FIG. 1 shows an arc extinguishing device according to the invention with a cut-out switching chamber insert
- FIG. 2 shows the arc extinguishing device according to FIG. 1 with fastening of the extinguishing plates on the switching chamber insert.
- FIG. 1 shows an arc extinguishing device of a switching device, which here essentially consists of an arc chamber 1 made up of a plurality of U-shaped die-cut extinguishing plates 2 which are assembled into a package.
- the legs or feet 3 of the quenching plates 2 surround a fixed 4 and a movable contact point 5 of the switching device.
- the two contact points 4 and 5 lie in an interior formed and shielded by the switching chamber insert 6.
- the feet or legs 3 are separated from the contact points 4 and 5 by walls 8 of the switching chamber insert.
- an insulating strip 7 is folded, which keeps the quenching plates 2 at a distance and at the same time holds them together to form an assembly.
