    摘要: A vacuum power circuit breaker having a vacuum-bulb interrupter unit comprising a vacuum bulb consisting of a cylindrical insulating envelope and end plates attached to the axial ends of the insulating envelope, stationary and movable electrode rods projecting into the vacuum bulb through the end plates, and metallic bellows assemblies connecting the stationary and movable electrode rods to the associated end plates of the vacuum bulb. Not only the movable electrode rod but the stationary electrode rod is thus axially movable relative to the vacuum bulb so that an impact applied to the stationary electrode rod when the movable electrode rod is connected to the stationary electrode rod is absorbed by the stationary electrode rod itself. The stationary electrode rod is held fixed independently of the vacuum bulb to prevent the electrode rod from being moved away from the movable electrode rod when the latter is moved and connected to the former. Means are provided for the purpose of preventing relative rotation between the electrode rods and the vacuum bulb so that the bellows assemblies are protected from being distorted when the stationary electrode rod is fixed to a stationary member.

    摘要: An operating device for effecting opening and closing operation of a vacuum interrupter with an electromagnet incorporated therein comprises a supporting resin block (4) for supporting a vacuum interrupter, a first pair of poles (47a) and a second pair of poles (47b), both extending along the outer circumferential surface of the supporting resin block (4), the length of the first pair being longer than that of the second pair. The operating device further comprises a mounting plate (49) of magnetic material directly connected to the first pair and connected to the second pair through connecting rod means, and an electromagnet (52, 56) fastened to the mounting plate (49), supported by the first and second pairs and connecting rod means (57). Thus, the supporting arrangement for supporting a vacuum interrupter not only serves as a mechanically supporting member, but also does a magnetic path defining member.

A vacuum power interrupting device comprises a disk-shaped resin supporting block 4 in which the vacuum interrupter is molded. A stationary electrode 23 is connected to a stationary contact rod 20 disposed within the vacuum interrupter. A tubular insulating barrier is integrally formed with the supporting block so as to surround the stationary electrode. The vacuum power interrupting device further comprises an electromagnet supported by a plurality of supporting poles 47a, 47b extending along the outer circumferential surface of the supporting block, and an adsorbed member 44 of a magnetic material responsive to the electromagnet and supported by an insulating rod 43 connected to the movable contact rod.

    摘要: An evacuated envelope includes a cylindrical housing made of a metallic material, disc-shaped upper and lower end plates made of ceramic and stationary and movable contact rods. The envelope of the vacuum interrupter is manufactured by brazing the end plates to the housing by using a sealing member made of a hermetically deformable metallic material which deforms by thermal stress generated during a cooling process after hermetic brazing. Sealing means of the envelope is provided with surface-to-surface sealing between the seal member and the cylindrical metallic housing or the disc-shaped end plate in order to enhance the sealing performance. The envelope is hermetically sealed by deforming the sealing member after brazing the sealing member to the housing in order to further enhance the sealing performance. The sealing member further comprises a stress absorbing means provided with a curved portion for absorbing thermal and mechanical stress.

    摘要: The invention provides a vacuum interrupter in which an evacuated envelope includes a cylindrical housing made of a metallic material, disc-shaped upper and lower end plates made of inorganic insulating material and stationary and movable contact rods. The envelope of the vacuum interrupter is manufactured by brazing the end plates to the housing by using a sealing member made of a plastically deformable metallic material which is deformed by thermal stress generated during a cooling process after hermetic brazing. The coefficient of the housing differs from that of the upper and lower end plates. According to the present invention, the sealing performance can be enhanced, even when the thermal coefficient of the housing differs from those of the end plates, since the sealing member is used.
