Abstract

A connecting sleeve generally used for a bus bar connection is produced from an insulating elastic material, often an elastomer material, having insulati ng properties which are deteriorated by partial discharges and decrease over th e operating time of the switchboard system. According to the invention, so- called partial discharge measuring methods must be carried out, inter alia also in the UHF range (UHF: ultra high frequency), in order to identify damaging effects on the insulating material in time. For the reliable and simple detection of the measuring signals, the connecting sleeve (M) has an outer, electroconductive surface (OA) which is earthed, and an inner, electroconductive surface (OI) to which the voltage potential of the bus bar (S) is applied, in addition to a coupling electrode (KE) which is integrated into the insulating material (I).

Claims (7)

1. Connecting sleeve (M) for a bus bar connection (SK) that is used to connect two switchboard sections (F1, F2) of a gas-insulated switchboard system, in which the connecting sleeve (M) is a an insulating, elastic material (I) that is in the form of a tube, characterized in that the connecting sleeve (M) has an outer, electrically conductive surface (OA) that is grounded, and an inner, electrically conductive surface (OI) to which the voltage potential of the bus bar (S) is applied; and in that the connecting sleeve (M) has a coupling electrode (KE) that is imbedded in the insulating material (I).
2. Connecting sleeve (M) as defined in Claim 1, characterized in that the coupling electrode (KE) has a sensor surface that is tangential to the outer surface (OA).
3. Connecting sleeve as defined in Claim 1 or Claim 2, characterized in that the coupling electrode (KE) is so imbedded in the insulating material (I) that the coupling electrode (KE) is electrically insulated from the inner surface (OI) and from the outer surface (OA), the coupling electrode (KE) having an edge area (R) that overlaps the outer surface (OA), at least in part.
4. Connecting sleeve (M) as defined in Claim 1, characterized in that the coupling electrode (KE) is connected to a plug connector (S1) that is positioned in an opening (A) that is surrounded by the insulating material (I).
5. Connecting sleeve (M) as defined in Claim 4, characterized in that the plug connector (S1) can be connected to a mating element (S2); and in that the opening (A) is matched to the outer shape of this counter element (S2) so a to form a dust-proof plug-type connection.
6. Bus bar connection (SK) with a connecting sleeve (M) to connect two switchboard sections (F1, F2) of a gas-insulated switchboard system, in which the connecting sleeve (M) is of an insulating, elastic material (I) and is in the form of a tube, characterized in that the connecting sleeve (M) has an outer, electrically conductive surface (OA) that is grounded, and an inner, electrically conductive surface (OI) to which the voltage potential of the bus bar (S) is applied; and in that the connecting sleeve (M) has a coupling electrode (KE) that is imbedded in the insulating material (I).
7. Gas-insulated switchboard system, in particular a gas-insulated medium-voltage switchboard system, with at least two switchboard sections (F1, F2) that are connected to one another through a bus bar connection (SK) that incorporates a connecting sleeve (M), the connecting sleeve (M) being of an insulating, elastic material (I) and being in the form of a tube, characterized in that the connecting sleeve (M) has an outer, electrically conductive surface (OA) that is grounded, and an inner, electrically conductive surface (OI) to which the voltage potential of the bus bar (S) is applied; and in that the connecting sleeve (M) has a coupling electrode (KE) that is imbedded in the insulating material (I).
