摘要： The invention relates to a switchgear arrangement with a switch path (2), comprising an insulating material nozzle (7). The insulating material nozzle (7) at least partly encloses the switch path (2). A nozzle channel (8) for the insulating material nozzle (7) opens with a outlet opening (13) in a hot gas space (10). A deflector element (15a, 15b, 15c) is arranged within the hot gas space (10) which defines a deflector channel (14a, 14b, 14c). The deflector channel (14a, 14b, 14c) comprises a section which has an expanding cross-section in the stream direction of a switching gas in the hot gas space (10).
