Definitions

  • the invention relates to a vacuum interrupter according to the preamble of claim 1.
  • a vacuum interrupter is known from US Pat. No. 3,231,704.
  • the elastic 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.
  • US-PS 3082307 corrugated connection flanges can be found for fastening ceramic tubes to a stud bolt of a vacuum interrupter.
  • this patent does not contain any reference to an elastic connection between the stud and the housing.
  • the object on which the present invention is based is to increase the inrush current of a vacuum interrupter according to the preamble of claim 1.
  • 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.
  • the elastically deformable ring is advantageously designed to be flat if the greatest possible mobility in both directions is desired. It can also have the shape of a truncated cone, the smaller surface of which advantageously faces the soldering flange when through the vacuum forces exerted on the flange are to be absorbed by the flange in the form of stresses
  • Fig. 1 shows a switching tube according to the invention in a partially cut and broken view.
  • FIGS. 2 and 3 show two embodiments of a flange according to the invention.
  • a switching tube has contacts 10 and 11 which are aligned with one another, of which the fixed contact is fastened to a stud 9.
  • an elastic flange 8 is attached via a housing ring 12, which carries a ceramic ring 7 and thus the entire housing of the vacuum interrupter.
  • the elastic flange 8 is composed of a solder flange 1, a cylinder wall 2, an elastically easily deformable ring 3 and a cylindrical part 4.
  • the solder flange 1 is brazed to the metallized end face 6 of the ceramic tube 7.
  • An Agcu eutectic advantageously serves as the solder.
  • the cylinder wall 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 appreciably, 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 , which is adjacent to the solder flange, embrittlement of the material occurs.
  • the elastic, easily deformable ring 3 is free from such a disturbance of the lattice structure.
  • the adjoining cylindrical Tei1 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 fed in during welding will.
  • the weld is advantageously carried out only in the forehead area, the remaining, not welded part of the ring also gives a distance from the elastically deformable ring.
  • the movable contact 11 is connected to the housing in a vacuum-tight manner via a bolt 13 and a bellows 12.
  • the elastically easily deformable ring 3 is flat according to FIG. 2. It therefore ensures a particularly high degree of mobility in the axial directions.
  • the elastically easily deformable ring 5 is frustoconical, the smaller cut surface of the truncated cone facing the solder flange 1.
  • This embodiment 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 flange 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.
