- the invention has for its object to provide an improved interrupter unit for a circuit breaker.
- An interrupter unit of the invention for a Leis ⁇ tung switch comprises two electrically conductive arcing contact pieces, an insulating nozzle, a heating volume, a separator housing, a cold gas duct and a hot-gas duct.
- the arcing contact pieces are along a contact gap between a see-off position in which the arcing contact pieces are separated by the switching path, and a closed position in which the arcing contact pieces are in galvanic contact with each other, relatively movable.
- the insulating nozzle surrounds the switching path at least partially.
- the separating housing divides the heating volume into a cold gas and a hot gas region and has at least one connecting opening connecting the cold gas region to the hot gas region.
- the cold gas passage extends through a nozzle channel end portion of the nozzle channel and is connected to the cold gas portion of the heating volume.
- the hot gas channel runs through the nozzle channel end section of the nozzle channel and is connected to the hot gas region of the heating volume.

Under a ⁇ OFF operation, a movement of the arcing contact pieces of the closed to the open position is in this case understood to.
- the hot gas channel allows the conduction of insulating gas between the arc chamber, in which the arc burns in the nozzle channel, and the heating volume.
- heated and expanding iso- liergas passed into the heating volume and increases the pressure in the heating volume.
- An embodiment of the invention provides that a first arcing contact piece has a contact end with a contact opening, in which the second arcing contact piece is retracted in the closed position, and that the hot gas channel surrounds the contact end of the first arcing contact piece, while the cold gas channel surrounds the hot gas channel. Because the hot gas channel is the contact end of the first arcing contact piece
- the hot gas channel Surrounds arcing contact and the cold gas channel surrounds the hot ⁇ gas channel, the hot gas channel is released at a separation of the arcing contact pieces rather than the Kaltgasbe ⁇ rich.
- pressure is built up in the heating volume via the hot gas duct at a time at which the cold gas duct is not yet released. Due to the delayed release of the cold gas channel is achieved that at this time, the pressure difference between the arc chamber and the heating volume is lower, whereby only a little hot gas passes through the cold gas duct into the heating volume.

From- Guiding the channel partition as part of the separating housing made ⁇ light a one-piece design of the separating housing and the channel partition and thereby simplifies the manufacture and assembly of the separating housing and the channel partition.
- the training takes into account the channel partition as a facing the switching path housing end of the separator housing such that along the switching path is no sufficient space for receiving the separation housing available as relatively moving in the ⁇ sem area of the interrupter unit blocks the Lichtbogennapstü- each other.
- the funnel-like design of the separating housing allows a suitable distribution of the heating volume in a cold gas region and a hot gas region and the formation of the cold gas channel and the hot gas channel through the separating housing.

- Another embodiment of the invention provides a compression volume, which is separated by a wall from the compression Schuvolu ⁇ men.
- the compression wall is coupled to an arcing contact piece such that it reduces the compression volume upon relative movement of the arcing contacts from the on position to the off position.
- the compression element at least one Kompressi ⁇ onswandö réelle, which is 29los- sen by a spill valve when the pressure in the heating volume is greater than the pressure in the compression volume.
- the compression Onsvolumen by the spill valve advantageously strigos ⁇ sen, so that no insulating gas escapes pressure-reducing from the Schuvolu ⁇ men in the compression volume.
- the overflow valve closes at least one connection opening between the cold gas region and the hot gas region of the heating volume when the pressure in the heating volume is less than the pressure in the compression volume.
- This further embodiment of the invention uses the overflow valve not only for closing the compression volume at high pressures in the heating volume, but also for at least partially closing the hot gas region at low pressures in the hot gas region.
- a further embodiment of the invention provides that the cold gas duct projects further into the nozzle channel than the hot gas channel.
- This embodiment of the invention also causes the hot gas channel to be released in the event of a separation of the arcing contact pieces, rather than the cold gas region having the advantages already mentioned above.

- the valve position of the spill valve 41 depends on the pressure difference between a pressure in the compression volume 28 and a pressure in the hot gas area 32. When the pressure in the compression volume 28 is smaller than the pressure in the hot gas area 32, the spill valve 41 assumes the first valve position. When the pressure in the compression volume 28 is greater than the pressure in the hot gas region 32, the spill valve 41 assumes the second valve position.
