Abstract (en)
[origin: WO9740507A1] An interrupter unit of a high-voltage power circuit breaker has two arcing contact pieces (1, 2), between which an arc (4) is struck in the event of a break. An insulated nozzle (3) is provided for blowing the arc (4). The insulated nozzle (3) is screwed into a cylindrical component (5) of the interrupter unit with the aid of a screw thread. To secure the screw connection, a connection piece (7) is provided which can be screwed into or, alternatively, onto the insulated nozzle (3) and which has a knurl (10) that can be pressed into the insulated nozzle.
