Abstract (en)
[origin: WO2021018426A1] The invention relates to an interrupter unit comprising a vacuum interrupter (4) and an insulating housing (6), wherein the insulating housing (6) has an inner surface (8) and the vacuum interrupter (4) is bordered at least partially by an electrically insulating structure material (22), which has an outer surface (10), and the insulating housing (6) at least partially surrounds the vacuum interrupter (4), wherein, in a ready-for-operation state of the interrupter unit (2), the inner surface (10) of the insulating housing (6) and the outer surface (10) of the vacuum interrupter (4) are separated by an adhesion layer (12), characterised in that both the inner surface (8) and the outer surface (10) are provided at least partially with an electrically conductive layer (14, 16), such that, in a boundary region (18) between the vacuum interrupter (4) and the insulating housing (6), there is the following layer sequence directed radially outwards from a switch axis (20): structure material (22) of the vacuum interrupter; outer surface (10) of the structure material (22); conductive layer (16) on the outer surface (10) of the structure material (22); adhesion layer (12); conductive layer (14) on the insulating housing (6); inner surface of insulating housing (8); and volume material (24) of the insulating housing (6).
