Abstract: The present invention relates to a device for interrupting non-short circuit currents only, and in particular relates to a disconnector, more particularly high voltage disconnector, or to an earthing switch, more particularly make-proof earthing switch, and further relates to a low voltage circuit breaker. The device comprises at least two contacts movable in relation to each other between a closed state and an open state and defining an arcing region, in which an arc is generated during a current interrupting operation and in which an arc-quenching medium comprising an organofluorine compound is present. According to the application, a counter-arcing component is allocated to the arcing region, the counter-arcing component being designed for counteracting the generation of an arc and/or being designed for supporting the extinction of an arc.

Abstract: A device or component thereof is provided for generation, transmission, distribution and/or use of electrical energy. In at least one insulation space formed within the device, there is a current-conducting component. The insulation space includes a dielectric insulation medium that surrounds the current-conducting component. This insulation medium includes a) at least one organofluorine compound selected from the group consisting of fluoroketones, fluoronitriles, and mixtures thereof and b) a carrier gas comprising at least one component selected from the group consisting of air, an air component, CO2, or a mixture of these components. The device includes at least one gas seal for sealing of the at least one insulation space from a further space. The gas seal includes butyl rubber as seal material.

Abstract: The present invention relates to a refill-container for replenishing and/or reconditioning an insulation fluid contained in an insulation space of an electrical apparatus. At least a portion of the interior of the refill-container defines a refill-fluid containment space, in which a refill-fluid comprising an organo-fluorine compound is contained. According to the invention, the refill-container further comprises an opening designed to be brought from a sealed state, in which the refill-fluid is hermetically contained in the refill-containment space, to an open state, in which the refill-fluid is allowed to flow through the opening out of the refill-containment space into the insulation space.
