Abstract:
1. An interrupter unit for a high-voltage circuit breaker, comprising: two contact pieces which are arranged coaxially opposite in a longitudinal direction and form a switching gap; and a hollow channel which runs coaxially with respect to the contact pieces in a longitudinal direction and in whose interior a quenching gas flows along during a switching process in a first direction which continues from the switching gap, and on an outer circumference of the channel the quenching gas flows along in a second direction, which is in an opposite direction to the first direction, with at least a part of the interrupter unit being arranged in a supporting manner, coaxially with respect to the channel and surrounding it, and with the quenching gas flowing in the second direction being arranged radially thereto, including a mounting element, which, has a first section and a second section, which extends radially opposite the first section, with the second section being supported by the first section, and the at least one part of the interrupter unit being supported by the second section, and an outlet flow opening, which points in the first direction, for the quenching gas being formed between the two sections and in an area of the connection of the first and second section.
