Abstract: The disclosure relates to an electrical switching device, which switches stroke-dependently, with extended switching hysteresis, including a switching element with a contact lever, the switching element cooperating with an actuating element movably guided in a holding device. The actuating element has a step-shaped portion for actuating the contact lever of the switching element and the actuating element has an opening in which an engagement element designed as a bolt or a pin engages when a switching action is initiated. The opening provided in the actuating element is formed as an elongated hole, in which the engagement element engages in order to achieve a switching stroke and a defined hysteresis is thus set depending on the design of the elongated hole.

Abstract: A hydraulic connecting bush for correcting hydraulic lines for hydraulic circuit-breaker drives, having a hollow cylindrical main body with at least two annular grooves, extending circumferentially on the main body outer cylindrical surface and having sealing rings inserted therein, the main body being made of a material having a first elasticity modulus. The bush may be configured for overlapping insertion in hydraulic lines to be connected, in contact with each other at end faces, the hydraulic lines being made of a material having a second elasticity modulus, a gap forming between, the main body and the hydraulic lines, such that if the first elasticity modulus is less than the second elasticity modulus, and an internal pressure is applied, the main body expands more than the hydraulic lines and closes the gap in the region of the sealing rings.

Abstract: A storage module for a hydraulic stored-energy spring mechanism for operating a high-voltage switch, for example a high-voltage circuit breaker, having a spring element which acts to store energy and having a fluid for transmitting the energy of the spring element, by a moving storage piston, to a piston rod for operating the high-voltage switch, wherein the storage piston projects into the housing which is filled with fluid and the housing forms a pressurized storage reservoir for the fluid. The pressurized storage reservoir is connected to a hydraulic system of the stored-energy spring mechanism by at least one channel element which projects into the pressurized storage reservoir and a pressurized channel which is connected to the channel element. The storage piston closes a subregion of the channel element starting from a specific piston stroke “s”.

Abstract: A hydraulic valve for connecting a first fluid-conducting pressure line to a second fluid-conducting pressure line in an actuator for activating a high- or medium-voltage circuit breaker includes a housing with a first channel inlet for attachment to the first pressure line, and with a second channel inlet for attachment to the second pressure line, and a cavity situated between the first and the second channel inlet. The hydraulic valve includes a sealing body which can move in the cavity and has a circumference which is greater, at least at one point, than the respective circumference of openings adjoining the cavity, of the first and the second channel inlets. The sealing body is geometrically matched to the cross-section of these openings to completely seal the openings when seated. First and second spring elements connected to the sealing body project into the cavity in the relaxed state.

Abstract: A differential cylinder for a hydromechanical drive for actuating an electrical switch, for example a high-voltage switch, is disclosed which includes a first pressure region for applying a working pressure, a second pressure region, and a piston which is capable of moving in a movement region and which is movable depending on a pressure difference between the first and second pressure region. A damping device is provided which, in the event of a movement of the piston in the direction of the second pressure region, provides damping with respect to the movement of the piston in a section of the movement region, wherein the damping is adjustable.

Abstract: A differential cylinder for a hydro-mechanical drive for actuating an electric switch, for example, a high-voltage switch, can include a first pressure area to be loaded with an operating pressure, a second pressure area, and a piston which can be moved in a movement range as a function of the pressure difference between the first and second pressure area. A damping device is provided which, during a movement of the piston in the direction of the second pressure area in one section of the movement range, provides damping against the movement of the piston, wherein the damping is adjustable.
