Definitions

  • the invention relates to a vacuum interrupter according to the preamble of claim 1.
  • a vacuum interrupter is known from US-A-3,231,704.
  • this document does not contain any information about the devices for fastening the tube.
  • an end plate is connected to the ceramic tube of the housing via a deformable ring.
  • the deformable ring has a solder flange and an adjacent cylinder jacket.
  • the cylinder jacket absorbs different shape changes due to heat fluctuations, while the solder flange follows the changes in the dimensions of the ceramic tube due to its small wall thickness.
  • the US-A-3 082 307 shows corrugated connection flanges for fastening ceramic tubes to a stud of a vacuum interrupter. This patent, however, contains no reference to an elastic connection between the stud and the housing.
  • rings the cross sections of which have curved profiles.
  • the rings are at least soldered onto the ceramic parts.
  • a holding device should at least optionally be attached to the side of the movable contact.
  • the rings are to be made so stable that they can absorb the entire switching pressure without the solder joints between the rings and the ceramic parts being torn open. For this reason alone, the design is not suitable for high inrush currents and the resulting high switching pressures (e.g. 5000N).
  • the object on which the present invention is based is to prevent the housing from being destroyed by the mechanical forces acting on the switch contacts during the switch-on process and caused by the switch-on current, even at very high switch-on current values.
  • the vacuum interrupter according to the invention is insensitive to longitudinal vibrations and bending vibrations which can occur as a result of a switching operation. It therefore requires considerably less effort to dampen the switch pole vibrations when installed in a circuit breaker. It can also be operated at higher inrush currents without being destroyed by the mechanical forces occurring at the switch poles.
  • the elastically deformable annular region is advantageously designed to be flat, it lying in a plane extending radially to the switching tube axis if the greatest possible mobility in both directions is desired. It can also enclose an angle of less than 90 ° with the second cylindrical region if the forces exerted on the flange by the vacuum are to be absorbed by the flange in the form of tensile stresses.
  • Figures 2 to 4 show two embodiments of an intermediate piece according to the invention in a sectional view.
  • a switching tube has contacts 10 ′ and 11 that are aligned with one another, of which the fixed contact 10 is fastened to a stud 9.
  • An intermediate piece 8 which carries a ceramic ring 7 and thus the entire housing of the vacuum interrupter, is fastened to the stud bolt via a housing ring 12.
  • the intermediate piece 8 is composed of a soldering flange 1, a cylindrical wall-shaped area 2, an elastically easily deformable annular area 3 and one cylindrical wall-shaped area 4 together.
  • the solder flange 1 is brazed to the metal end face 6 of the ceramic tube 7.
  • An AgCu eutectic advantageously serves as the solder.
  • the cylindrical wall-shaped area 2 is stiff due to its shape when the housing vibrates in or perpendicular to the direction of the housing axis, it does not take part in these vibrations noticeably, a disturbance of its lattice structure by the solder does not affect the life of the tube, even if this means at least in the Area adjacent to the solder flange where the material becomes brittle.
  • the elastic, easily deformable annular region 3 is free from such a disturbance of the lattice structure.
  • the adjoining cylindrical wall-shaped area 4 is welded to the housing ring 12. This means that there is no disruption to the lattice structure since, unlike soldering, no foreign metals are added during welding.
  • the welding is advantageously carried out only in the end region, the remaining, not welded part of the cylindrical wall-shaped region 4 results in a distance from the weld seam to the elastically deformable ring 3.
  • the movable contact 11 is connected to the housing in a vacuum-tight manner via a bolt 13 and a bellows 14.
  • the elastically easily deformable annular region 3 is flat as shown in FIG. 2 and lies in a plane extending radially to the axis of the switching tube. It therefore ensures particularly high mobility in the axial direction.
  • the elastically easily deformable annular region 5 forms an angle with the cylindrical region 4 at less than 90 °.
  • This embodiment partially absorbs the compressive force exerted on the housing as a result of the vacuum inside the tube as tensile stress. This embodiment enables a particularly thin wall thickness of the intermediate piece 8.
  • the curved region 6 has an arcuate cross section. This embodiment has proven to be particularly stable and advantageous with the vibrations that occur.
