A vacuum interrupter includes a housing having at least one annular ceramic insulating element which forms a vacuum chamber. A contact system has two contacts which are movable relative to one another. A capacitive element has two electrodes and a dielectric material disposed between the electrodes. The capacitive element is form-lockingly mounted on the insulating element and has a capacitance between 400 pF and 4000 pF. A high-voltage switching assembly including the vacuum interrupter is also provided.

A method for producing a solid-insulated circuit-breaker pole includes forming a pole shell housing with an elastic layer that is integrally joined to the pole shell housing; and mounting a vacuum fault interrupter into the pole shell housing provided with the elastic layer. Also disclosed is a solid-insulated circuit-breaker pole.

A bi-stable mechanism for a vacuum interrupter. The bi-stable mechanism includes an actuator; and a cam pivotable by the actuator, the cam moving a moveable contact. Wherein a bellows assembly is positioned above a vacuum bottle and coupled to a housing. The bellows assembly includes an outer cylindrical shell surrounding an opening spring, a spring plate, a contact spring, and a bellows. The bellows assembly reciprocates the moveable contact to prevent arcing between a pair of contacts and biasing the pair of contacts apart from each other.

A pole part for medium voltage switchgear includes: a vacuum interrupter embedded in an insulating housing including at least one of epoxy, a bulk moulded component, or a thermoplastic or plastic material, a bottom part of the insulating housing including a mechanical fixation device for fixing the pole part on a support element. The bottom part of the pole part includes a casted on or moulded on axial externally or internally threaded section that includes an insulating material.

A circuit interrupting device including a vacuum interrupter, a separable ceramic capacitor, and an insulating housing. The vacuum interrupter includes a vacuum bottle and first and second contacts disposed within the vacuum bottle. The second contact is movable relative to the first contact between a closed position and an open position. The separable ceramic capacitor is electrically connected in parallel with the vacuum interrupter provided over an outer surface of the vacuum bottle. The insulating housing encloses the separable ceramic capacitor and the vacuum interrupter.

A vacuum interrupter for interrupting a voltage. The vacuum interrupter including a vacuum bottle, a hi-stable mechanism, and a bellows assembly. The vacuum bottle having axially separable contacts, wherein at least one of the contacts is a moveable contact. The bi-stable mechanism including an actuator, and a cam pivotable by the actuator, the cam moving the moveable contact. The bellows assembly reciprocating the moveable contact to prevent arcing between the contacts. The bellows assembly including a spring biasing the contacts apart from each other.

A switching apparatus includes: a body including: a sidewall that extends from a first end to a second end, the sidewall defining an interior space; and a plurality of electrically insulating sheds that extend radially outward from an exterior surface of the sidewall; a circuit interrupter in the interior space of the body; a first terminal electrically connected to the circuit interrupter;

and a second terminal electrically connected to the circuit interrupter. The switching apparatus is configured to be mechanically connected to at least two different types of mounting structures.

An electrical switching device includes a kinematic chain, a first encapsulation housing, a movable switching contact piece and a fixed switching contact piece. The movable switching contact piece is movable by the kinematic chain which penetrates the first encapsulation housing in a fluid-tight manner. The kinematic chain penetrates the first encapsulation housing in a linearly movable manner.

A vacuum interrupter tube contains at least one insulating body, a fixed contact, a fixed contact flange, a moving contact having a longitudinal axis, a moving contact flange, and a bellows. The fixed contact is stationarily arranged in the fixed contact flange. The moving contact is moveably guided and the moving contact is moveably secured to the moving contact flange by the bellows. The bellows is secured to the moving contact flange by a first bellows end and the bellows is secured to the moving contact by a second bellows end. Therein the vacuum interrupter tube is protected against the deformation of at least one of the fixed contact flange and the moving contact flange due to an ambient pressure of the vacuum interrupter tube of over two bar by a stiffened fixed contact flange and/or a stiffened moving contact flange.

A reinforcement structure for a vacuum interrupter is disclosed. For example, in some implementations, a vacuum interrupter includes a first electrical contact; a second electrical contact; a vessel that encloses the first electrical contact and the second electrical contact in an evacuated space, the vessel including an endcap; and a reinforcement structure at an exterior surface of the endcap, the reinforcement structure including a first side, a second side, and an opening that passes through the reinforcement structure from the first side to the second side. The exterior surface of the endcap includes a recessed region, and at least a portion of the opening is positioned over the recessed region.
