Abstract: The operating method uses a current rail coupler (S2) between each 2 current rails (I,II) for the electrical switchgear, which is normally held in the closed position for providing an electrical connection between the current rails and which is opened during switching operation of the switchgear, or in response to a fault. The current rail coupler may be opened after opening a current rail switch (S1) ,inserted in one of the current rails between an energy supply block (EB) and an energy transfer block (TB). An Independent claim for an electrical switchgear is also included.

Abstract: The spacers (5) are electrically conductive and contact adjacent sensor sections (2). The voltage sensor (1) high tension section is qualified for open air use. This derives from the high tension dielectric and protective screen (against weather) surrounding the assembly of sensor- and spacer sections. The sensor is made of individual sections, and a continuous sensor fiber (4a). In each section, a given length of optical fiber is fastened to the body (3) such that its length is varied only by E-field components parallel to the sensor axis. The amplification factor of each section is proportional to its length, in correspondence with the piezoelectrically-induced length variation of the fiber. Sensor sections and spacers are cylindrical and aligned along the sensor axis. Between sensors and spacers, there are conductive flexible holders (6). The holders include inner- and control electrodes, with spring sections. Inner electrodes bond and interlock with the end surfaces of sensor elements. Control electrodes are fastened onto the inner electrodes. Spring sections connect the inner electrodes to adjacent spacer sections. The dielectric is an elastomer or insulating fluid. The protecting screen is an elastomer with additional support insulator. The silicone body may have an additional fiberglass-reinforced plastic insulating rod. A version using a dielectric of transformer- or silicone oil is also described. The connection contacts (1a) of the high tension section comprise flanges, a hanger and a corona- and/or voltage control ring. An earthing and anchoring cable is included.

Abstract: Die Messeinrichtung ist für den Einsatz in isoliergasgefüllten, metallgekapselten gasisolierten Schaltanlagen vorgesehen. Sie weist mindestens einen mit einer optischen Glasfaser versehenen, entlang einer zentralen Achse (25) erstreckten Quarzkörper (34) als Sensor auf.
Es soll eine faseroptische Messeinrichtung geschaffen werden, die in ein vergleichsweise einfach ausgebildetes, kompaktes und kostengünstiges Gefäss eingebaut ist. Dies wird dadurch erreicht, dass der Sensor in einem separaten Volumen (40) im Innern der Schaltanlage angeordnet ist, welches von einem unteren Endflansch (28) und einem oberen Endflansch (30) und einem mit diesen druckdicht verbundenen Isolierrohr (29) begrenzt wird, dass der untere Endflansch (28) elektrisch leitend mit einem mit Hochspannung beaufschlagten Aktivteil (22) der Schaltanlage und mit der unteren Stirnseite des Quarzkörpers verbunden ist, und dass der obere Endflansch (30) elektrisch leitend mit der geerdeten Kapselung (21) der Schaltanlage und mit der oberen Stirnseite des Quarzkörpers verbunden ist.
