Abstract

A switching arrangement has a first contact set and a second contact set which can be moved with respect to the first contact set, and an insulating nozzle arrangement. The insulating nozzle arrangement is supported on the first contact set which includes a first arcing contact piece. The first arcing contact piece can be moved with respect to the insulating nozzle arrangement.

Claims (20)

1. A switching arrangement, comprising:

a first contact set;

a second contact set movably mounted relative to said first contact set;

an insulating nozzle arrangement supported on said first contact set, said insulating nozzle arrangement having a main nozzle and an auxiliary nozzle commonly delimiting a nozzle channel, with said main nozzle and said auxiliary nozzle each delimiting a portion of said nozzle channel; and

said first contact set having an arcing contact piece movably mounted relative to said insulating nozzle arrangement enabling a relative movement between said first arcing contact piece and said insulating nozzle arrangement.

2. The switching arrangement according to claim 1 , wherein said insulating nozzle arrangement delimits a nozzle channel formed with a mouth opening arranged opposite a mouth opening of a channel of said arcing contact piece.

3. The switching device arrangement according to 2 , wherein said nozzle channel serves to convey a fluid medium, and fluid medium exiting from said mouth opening of said nozzle channel flows into said channel.

4. The switching device arrangement according to 2 , wherein said arcing contact piece has a contact socket and said channel is surrounded, at least in portions, by said contact socket of said arcing contact piece.

5. The switching device arrangement according to 1 , wherein said first contact set has a first nominal current contact piece carrying said insulating nozzle arrangement at least in part.

6. The switching device arrangement according to 5 , wherein said first arcing contact piece is surrounded at least in portions by said first nominal current contact piece.

7. The switching device arrangement according to 5 , wherein said first arcing contact piece and said first nominal current contact piece are movably mounted relative to one another.

8. The switching device arrangement according to 5 , wherein said second contact set has a second nominal current contact piece and a second arcing contact piece, and wherein each of said first and second arcing contact pieces are movable in relation to each of said first and second nominal current contact pieces in order to generate a relative movement therebetween.

9. The switching device arrangement according to 1 , wherein:

said first contact set has a first arcing piece and a first nominal current contact piece;

said second contact set has a second arcing contact piece and a second nominal current contact piece; and

each of said first and second arcing contact pieces and each of said first and second nominal current contact pieces perform switching movements driven by a common drive arrangement.

10. An actuation method for switching a switching arrangement having a first contact set with a first arcing contact piece, a second contact set that is movable relative to the first contact set, and an insulating nozzle arrangement supported on the first contact set, the method which comprises:

on occasion of a switch-on procedure, moving the first contact set and the second contact set towards one another, and thereby reducing a spacing distance of the first arcing contact piece from the insulating nozzle arrangement by moving the first arcing contact piece relative to the insulating nozzle arrangement.

11. The actuation method according to 10 , which comprises, for a switch-on procedure, following an initiation of a switching movement of the first contact set, moving the first arcing contact piece out from a field shadow of a first nominal current contact piece.

12. The actuation method according to 10 , which comprises, for a switch-off procedure, enlarging a distance between the first arcing contact piece and the insulating nozzle arrangement before a switching arc is extinguished.
