摘要： A vacuum circuit interrupter includes an evacuated envelope composed of a plastically deformable metallic cylinder and first and second insulating disks closing the opposite ends of the cylinder. Stationary and movable conductive rods project coaxially through the first and second disks respectively. Stationary and movable electrodes are connected to the stationary and movable rods in such a manner as to engage with each other when the movable rod moves toward the stationary rod and disengage with each other when the movable rod moves away from the stationary rod. A bellows surrounds the movable rod inside the envelope and is fixed at its one end to the movable rod and at its other end to the second disk in such a manner as to provide a seal about the movable rod to allow for movement thereof without impairing the vacuum inside the envelope. A first conductive shield surrounds the stationary rod inside the envelope. The first shield is fixed to the first disk in such a manner as to be isolated electrically from the stationary rod and the metallic cylinder. A second conductive shield surrounds the bellows. The second shield is fixed to the second disk in such a manner as to be isolated electrically from the movable rod and the metallic cylinder.

摘要： A vacuum circuit interrupter includes a cylinder made of a metal relatively easy to deform plastically, and first and second insulating disks closing the ends of the metallic cylinder to form therewith an evacuated envelope. A stationary rod enters the envelope through the first disk in such a manner as to provide a seal therewith. A movable conductive rod movably enters the envelope through the second disk. A bellows is fixed at its one end to the movable rod and at its other end to the second disk in such a manner as to provide a seal about the movable rod to allow for movement thereof without impairing the vacuum inside the envelope. Stationary and movable electrodes are connected to the stationary and movable rods respectively in such a manner as to engage and disengage with each other according to the movement of the movable rod.

摘要： A vacuum interrupter for electric power having a vacuum vessel into which a pair of electrode holders each having an electrode contact brazed to the end thereof are in contact with each other when the device is closed and are separated from each other when the device is open. The vacuum vessel comprises: (a) an insulating envelope made of ceramic or crystallized glass having a metallized layer at each end thereof; (b) a first metallic end plate made of copper to the periphery of which one metallized layer of the insulating envelope is brazed; (c) a second metallic end plate made of copper to the periphery of which the other metallized layer of the insulating envelope is brazed; (d) an arc shielding member located within the insulating envelope so as to surround the pair of electrode contacts and be brazed to the second metallic end plate at one end thereof; and (e) a bellows located within the arc shielding member brazed to the electrode holder at one end thereof and to the second metallic end plate at the other end thereof. Both the first and second metallic end plates are made of copper, and are annealed during the brazing operation so that they are easily deformed plastically, whereby thermal stress generated between the end plates and the insulating envelope is absorbed into these plastically deformable end plates and the insulating envelope and brazed joints are not destroyed.
