Definitions

  • the invention relates to a vacuum switching chamber and a method for producing the same according to the preamble of claims 1 and 3.
  • the vacuum switching chamber consists of a metallic body which is evacuated in the interior and in which the switching contacts are located.
  • Vacuum switch chambers of this type are usually introduced into epoxy resin or casting resin, or sheathed by the same. It should be noted that the coefficients of expansion and other temperature parameters of casting resin are different than those of the metal used in the vacuum interrupters. In operation, but also in the production of mechanical stress can therefore arise when pouring such vacuum interrupters by different thermal expansion coefficients that ensure no conclusive contact between the metal surface of the vacuum interrupter and the sprue.
  • padding coatings of the vacuum interrupters consist of an elastic material and surround the vacuum interrupter interlocking.
  • the vacuum interrupter chamber is then encapsulated with the already surrounding coating or sheathing made of elastic material with epoxy resin.
  • EP 0 866 481 A1 is the basic use of a cushion layer between the vacuum chamber and Epoxyinguss provided.
  • the materials mentioned there are cold shrink materials.
  • EP 0187 960 A1 is also known such a ring. Although no tools for applying the same are given, but no measures are taken in the subsequent hot casting process that the ring remains conclusive on the vacuum chamber even at high temperature.
  • the switching chamber would not be placed there and if the mechanical expansion means had been removed, then the diameter of the thus relaxed elastic tube would be smaller than the outer diameter of the vacuum chamber. Because of these known and already advantageously used in the prior art parameters, it comes to the above-described conclusive attachment to the surface.
  • the invention is therefore based on the object to improve a vacuum interrupter chamber of this type and a method for producing the same respectively the subsequent potting to the effect that the advantages described above used but the disadvantages are avoided.
  • the core of the device according to the invention relating to the vacuum interrupter chamber is that the vacuum interrupter chamber is further provided with a protective sheath made of an elastic or elastomeric or plastic material on the outer surface in preparation for the subsequent encapsulation, which is heat shrinkable on the surface without further mechanical aids the vacuum interrupter chamber is applied.
  • a protective sheath made of an elastic or elastomeric or plastic material on the outer surface in preparation for the subsequent encapsulation, which is heat shrinkable on the surface without further mechanical aids the vacuum interrupter chamber is applied.
  • the dimensioning of the tube respectively its final dimensioning after heat shrinkage is designed so that it rests tightly around the cylindrical outer surfaces, and also at the ends also around the edges to the surface of the vacuum interrupter chamber at least partially invests.
  • a tube made of heat-shrinkable tubing which has a larger circumference in its state than that of the switching chamber is pulled over and positioned thereacross, and subsequently shrunk onto the surface of the vacuum interrupter chamber by a heat-shrinking process.
  • the hose can thus easily pull on the vacuum interrupter chamber and then bring by a simple process step quickly and very efficiently in equally dense and consistent system to the surface of the vacuum interrupter chamber.
  • the casting in epoxy resin is the heat shrink material compared to the previously used in the prior art materials which consist of rubber or silicone rubber or the like is a temperature-stable material in its consistency.
  • the subsequent Epoxydharzverguss also happens at a temperature of at least 130 degrees.
  • the heat shrink tube according to the invention materially and in its consistency stable and the sprue caused as such no aging of the material.
  • Fig. 1 To shrink a vacuum chamber 1 with a heat shrink tube 2, the chamber is coated with the expanded tube in the manner described.
  • the expansion of the tube can be done beforehand and thus no otherwise necessary mechanical means are more necessary when coating the heat shrink tube on the vacuum chamber.
  • the shape of the expanded tube favors the automation of the manufacturing process much more than was possible with known methods.
  • FIG. 2 shows how after the heat treatment, the shrink tubing applies to the vacuum interrupter chamber.
  • the thus created and firmly wrapped by the shrunk-on heat shrink tube vacuum interrupter is now surrounded by an Epoxidharzverguss, or embedded in such, which is not shown here.
  • the casting is applied directly to the outer skin of the heat shrink tubing.
