Abstract: A quenching chamber in medium-voltage switch disconnectors includes a body made of a gassing material that is of a solid shape similar to a rectangular prism. The chamber includes an arcing knife channel and an arc chamber hollowed in the body and is fitted with an arcing contact unit located in a socket. The arc chamber extends directly along the arcing knife channel from a back wall of the chamber and is connected with the inside of the arcing knife channel through a gap that forms a flat funnel. The height of the funnel decreases with an increase in the distance to the arcing knife channel. The width of the gap is less than the width of the arcing knife channel measured in a plane perpendicular to the side walls of the body.

Abstract: A circuit protection device is provided for use with a circuit that includes at least one pair of conductors. The protection device is configured to generate an arc. The protection device includes at least a pair of electrode assemblies electrically coupled to the at least one pair of conductors and a conductor base to support the pair of electrode assemblies. The protection device includes a cover coupled to the conductor base and defining at least one isolation chamber, wherein the electrode assemblies are disposed within the isolation chamber. The protection device includes a containment shield moveably coupled to the cover. The containment shield defines a containment chamber configured to contain charged particles produced by the arc. The containment shield is operative to move relative to the cover in response to a change in pressure produced by the arc within the containment chamber. An isolation assembly is coupled to at least one of the cover and the containment shield and configured to prevent the cover from contacting the containment shield.
