Definitions

  • the invention relates to an insulating material housing for accommodating and isolating stressed components in a one-piece and dimensionally stable sheathing which in a cross-sectional view extends circumferentially closed and is pierced by at least one through opening for receiving a connecting part which can be acted upon by voltage, ribs on the sheathing for increasing the Leakage current resistance are molded.
  • Such an insulating housing is known for example from DE 197 12 182 AI.
  • the insulating material housing disclosed there is made of cast resin and is provided for receiving and insulating a vacuum circuit breaker which is arranged in the interior of a tubular casing.
  • the casing projects above the vacuum circuit breaker with a hollow cylindrical collar section, in the side wall of which a through opening is provided for receiving a connecting part.
  • the connection part enables easy contacting of the vacuum circuit breaker with current conductors.
  • the collar section between its through-opening and a housing opening facing away from the vacuum circuit breaker has closed ribs which are molded around the outside of the collar section.
  • the known insulating material has the disadvantage that the ribs do not increase the tracking resistance.
  • a leakage current can rather go along the inside of the casing without detours via the outer ribs to earth poten- tial components flow.
  • the tracking resistance is thus determined by the length of the collar section.
  • the collar section In order to be able to meet the current leakage resistance requirements, the collar section must be made long enough. However, this leads to a space-consuming construction, which is usually undesirable.
  • DE 35 38 955 AI discloses an insulating material housing of a gas pressure switch, in which a tubular casing delimits a gas space for extinguishing an arc drawn between two switching contacts.
  • the tubular casing is provided with internal and external grooves, in the crossing points of which there are openings for the extinguishing gas.
  • the inner and outer grooves serve to mechanically stabilize the sheathing.
  • DE 39 23 205 discloses an electrical connection box with flat areas in which through openings and ribbed arches can be seen, which enclose through openings from several sides.
  • DE 195 03 347 AI describes a vacuum switch with a tubular casing that has closed inner ribs on its inside.
  • DE 31 45 391 C2 discloses a gas pressure switch with an insulating body, which is provided with circumferential gas guiding spaces and lamellae running in the longitudinal direction.
  • the object of the invention is to provide an insulating material housing of the type mentioned at the outset, which has a compact design and is simple and therefore inexpensive to produce.
  • the invention solves this problem in that the ribs are designed as rib arches, which enclose each passage opening from several sides.
  • the profiled area can therefore be limited to the area around the passage opening. Because each passage opening is delimited by ribbed arches from several sides, the leakage current is forced to flow over an area profiled by the ribs, the leakage path being increased according to the invention. It is by no means necessary for the costal arches to be closed and to run around the passage opening.
  • the costal arches can only limit the passage opening from three sides. In this case, however, it must be ensured that the path that the leakage current would have to take in order to bypass the costal arches is greater than the direct path to a component with different electrical potential.
  • the direct route could also be called a straight line.
  • the rib arches have rib sections on which the angles span each other, which are each between 0 and 180 degrees, for example between 60 and 120 degrees or preferably 90 degrees.
  • the casing consists of a dimensionally stable or rigid material. This excludes materials that give the sheathing such elasticity that it could be removed from an inner mold core after or during its completion while the material is stretching.
  • Epoxy resins such as cast resin or other thermosets or thermoplastics come into consideration as materials for the dimensionally stable insulating material housing.
  • the rib arches preferably have longitudinal ribs running in a longitudinal direction of the casing, which merge into at least one transverse rib running at right angles thereto and in the transverse direction of the casing.
  • the ribbed arches formed in this way are particularly easy to manufacture, as a result of which the costs of the insulating material housing are further reduced.
  • the costal arches are arranged inside the casing.
  • the transverse ribs are not closed circumferentially in a cross-sectional view of the casing.
  • a one-piece mold core used to form the inner ribs can therefore be used can be removed easily after the insulation housing has solidified.
  • the longitudinal ribs each have a longitudinal rib height such that, in a cross-sectional view of the casing, the longitudinal ribs and the transverse ribs bear against a common surface contour.
  • the longitudinal ribs and the transverse ribs thus jointly delimit a cavity through which electrical components can be inserted into or removed from the insulating material housing.
  • the longitudinal ribs and the transverse ribs are thus arranged in a quasi-alignment with one another and lie together on the contour of the usable cavity. In other words, the creepage distance in the longitudinal and transverse directions is optimized for a usable cavity, since ribs with a lower rib height than are necessary to insert the previously defined component are avoided.
  • the common surface contour is advantageously a circular contour. This allows, for example, the insertion or execution of a cylindrical vacuum switch into the insulating material housing.
  • FIG. 1 shows an exemplary embodiment of the insulating material housing according to the invention in a longitudinally sectioned view
  • Figure 2 shows the insulating housing according to Figure 1 in a cross-sectional view along the line II and
  • FIG. 3 shows the insulating material housing according to FIG. 1 in another longitudinal section.
  • Figure 1 shows an embodiment of the insulating material housing 1 according to the invention in a longitudinal section.
  • the insulating housing 1 has a sheathing 2 consisting of cast resin and outer ribs 3 as well as inner ribs 4, which are each molded onto the sheathing 2.
  • the insulating material housing is thus formed in one piece.
  • a cylindrical vacuum circuit breaker 5 can be seen in the insulating material housing, elastic material being provided between the casing 2 and the vacuum circuit breaker 5 to compensate for temperature-dependent volume fluctuations of the vacuum circuit breaker 5 during operation.
  • the vacuum circuit breaker 5 has in its interior a fixed contact and a related movably guided moving contact.
  • a switching rod 7 which is firmly connected to the moving contact, can be seen, via which a drive movement of a not shown
  • connection part 9 is arranged in a through opening 10 of the casing 2 and has a threaded connection opening 11, by means of which the attachment of a connection lead, not shown, is made possible.
  • the insulating material housing is tubular or hollow-cylindrical, the inner ribs 4 having longitudinal ribs 12 extending in the longitudinal direction of the casing 2 as well as transverse ribs 13 running at right angles thereto, the longitudinal ribs 12 at transition points 14 into the Pass over the transverse ribs 13.
  • ribbed arches are formed which surround the passage opening 10 from three sides. A potential leakage current from the connecting part 9 on its way to the free opening 15 of the casing 2 is thus forced to flow over the costal arches.
  • a crawl along the first longitudinal rib 12, which is closest to the through opening 10, then in the transverse direction past the two other longitudinal ribs 12, and finally via the non-profiled or rib-free area to the free opening 15 would be longer than the direct path from the connecting part 9 over the transverse ribs 13 down to the free opening 15.
  • the tracking resistance thus remains determined by the depth of the profiling of the inner ribs 4 or the outer ribs 3.
  • FIG. 2 shows the circuit breaker according to FIG. 1 in a cross-sectional view cut along line II. Only inner ribs 4 can be seen in this illustration. As can be clearly seen, the individual longitudinal ribs 12 have different rib heights, so that in this cross-sectional view they lie with the transverse ribs 13 on a common surface contour, which here is a partial circle. gen. In other words, the longitudinal ribs 12 are arranged in alignment with the transverse ribs 13. The partial circle delimited by the longitudinal ribs 12 and the transverse ribs 13 is a semicircle which is complementary to a semicircle which is delimited by the inner surface of the casing 2. Both semicircles form the overall circle 16 indicated in FIG. 2.
  • the total circle 16 represents the cross-sectional area of a cavity, which is cylindrical in shape and whose radial diameter is larger than the outside diameter of the vacuum circuit breaker 5, so that the vacuum circuit breaker 5 can be replaced even after commissioning without destroying the casing 2 or the insulating material housing 1 is.
  • the leakage current was thus optimized for a given cavity.
  • FIG. 3 shows a further longitudinally sectioned view of the insulating material housing according to FIG. 1, in which the multi-sided limitation of the passage opening 10 by the rib arches, that is to say by the longitudinal ribs 12 and the transverse ribs 13, is illustrated once again.
