摘要： According to one embodiment, a Vacuum interrupter includes a pair of electrodes provided such that their electrode opposed surfaces face each other, and an undulating structure provided in at least one of the electrode opposed surfaces. The undulating structure includes one or more projections which project from the electrode opposed surface, and depressions provided so as to be adjacent to the projections, respectively. The projections and the depressions are alternately provided in a direction crossing the electrode opposed surface. In a conducting state in which the electrodes are in contact with each other, the projections are in contact with the opposite electrode opposed surface.

摘要： A vacuum valve includes: an insulation container; a fixed-side electrode including a fixed-side contact, a fixed-side longitudinal magnetic-field coil generating a magnetic field on a surface of the fixed-side contact in an axial direction, and a fixed-side spacer; and a movable-side electrode including a movable-side contact, a movable-side longitudinal magnetic-field coil generating a magnetic field on a surface of the movable-side contact in the axial direction, and a movable-side spacer. The fixed-side longitudinal magnetic-field coil and the movable-side longitudinal magnetic-field coil each include an outer ring portion having an arc shape and a power feeding portion protruding from an end of the outer ring portion. The fixed-side or movable-side contact is brazed to the power feeding portion. The fixed-side and movable-side spacers are made of a material with lower conductivity than materials of the fixed-side and movable-side longitudinal magnetic-field coils, or made of an insulator.

摘要： A shield element for a vacuum interrupter for installation between an electrically conductive wall element and an electrically insulating wall element of a vacuum interrupter includes a connection region, a shield inner region and a shield outer region. The shield outer region can be disposed outside of and the shield inner region can be disposed within the vacuum interrupter. The connection region has a first structure and a second structure which prevent the formation of mechanical stresses after soldering of the vacuum interrupter. A vacuum interrupter, a method for producing a shield element and a method for producing a vacuum interrupter are also provided.

摘要： A vacuum interrupter (1) is equipped with a vacuum container (2) and a fixed electrode (3) and a movable electrode (4), which are provided in the vacuum container (2). The vacuum container (2) is constructed by hermetically joining a fixed-side end plate (6) to one end portion of an insulating tube (5) and by hermetically joining a movable-side end plate (7) to the other end portion of the insulating tube (5). The insulating tube (5) is equipped at its end portion with a projection portion (5a) that projects in an axial direction of the insulating tube (5) along an outer periphery of the insulating tube (5). The insulating tube (5) is equipped at its end portion with an end plate joining portion (5b) that projects from a base end portion of the projection portion (5a) in an inner peripheral direction of the insulating tube (5). The end plate joining portion (5b) is equipped on its surface with a metallized layer (8) to which the fixed-side end plate (6) (or the movable-side end plate (7)) is joined by brazing. The metallized layer (8) is equipped with a joining portion (8a) that extends in a radial direction of the insulating tube (5), and an extension portion (8b) that extends in an axial direction of the insulating tube (5) from an end portion of the joining portion (8a) on an inner peripheral side of the insulating tube (5).

摘要： 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.

摘要： A gas-insulated switching device includes: a vacuum valve having a movable contact provided on one side of a movable conductor and a fixed contact provided to a fixed conductor; an insulation rod connected to another side of the movable conductor led out from the vacuum valve through a bellows; an operation rod connecting the insulation rod and an operation device; an airtight container in which the insulation rod, the other side of the movable conductor, and the operation rod are accommodated; and an intermediate pressure chamber formed by communication between internal spaces of the bellows and the airtight container. A sliding contact member is provided to the other side of the movable conductor. The sliding contact member is connected, via the airtight container, to a main circuit conductor. A communication portion provided between the airtight container and the sliding contact member allows communication inside the airtight container.

摘要： 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.

摘要： In an electric contact including a base material, high-melting-point substance particles, and an intermetallic compound, the intermetallic compound containing a MnX compound (X represents Te or Se) and a compound of a Mn—Cu solid-solution phase and X, is dispersed in the base material. If the Vickers hardness of the high-melting-point substance particles is higher than 0 Hv and lower than 200 Hv, the particle diameter of the high-melting-point substance particles is not smaller than 0.1 μm and not larger than 100 μm. If the Vickers hardness of the high-melting-point substance particles is 200 Hv or higher, the particle diameter is not smaller than 0.1 μm and not larger than 10 μm. The mass of X atoms is not lower than 1.5 mass % and not higher than 15 mass %. The atomic weight ratio Mn/(Mn+X) is not lower than 20 at % and not higher than 80 at %.
