A connecting sleeve generally used for a bus bar connection is produced from an insulating elastic material, often an elastomer material, having insulating properties which are deteriorated by partial discharges and decrease over the 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).
Connecting sleeve for a bus bar connection that is used to connect two switchboard sections of a gas-insulated switchboard system, in which the connecting sleeve is an insulating, elastic material (that is in the form of a tube, characterized in that the connecting sleeve has an outer, electrically conductive surface that is grounded, and an inner, electrically conductive surface to which the voltage potential of the bus bar is applied;
Bus bar connection with a connecting sleeve to connect two switchboard sections of a gas-insulated switchboard system, in which the connecting sleeve is of an insulating, elastic material and is in the form of a tube, wherein the connecting sleeve has an outer, electrically conductive surface that is grounded, and an inner, electrically conductive surface to which the voltage potential of the bus bar is applied;
Gas-insulated switchboard system, in particular a gas-insulated medium-voltage switchboard system, with at least two switchboard sections that are connected to one another through a bus bar connection that incorporates a connecting sleeve, the connecting sleeve being of an insulating, elastic material and being in the form of a tube, wherein the connecting sleeve has an outer, electrically conductive surface that is grounded, and an inner, electrically conductive surface to which the voltage potential of the bus bar is applied;
