Definitions

  • the invention relates to an insulating part for a high-voltage electrical device, in particular for a high-voltage circuit breaker.
  • An insulating part is for example from the patent DE 198 26 202 C2 known.
  • these areas of the finished insulating part are irradiated with beta or gamma radiation.
  • Treatment with high-energy radiation influences the particle bonds of the insulating material.
  • embrittlement of the material occurs by breaking up the particle bonds.
  • the mechanical strength is reduced.
  • the thus treated Isolierstoffmaschine are to be generously dimensioned accordingly.
  • the invention has for its object to make an insulating part of the type mentioned in such a way that the insulating part has an improved mechanical strength.
  • an insulating part of the type mentioned in the present invention the insulating material first made of a granules partial volumes and second made of a granules partial volumes, wherein the granules for the production of the first partial volumes by treatment, an increased electrical conductivity over the granules for the production of the second partial volumes and wherein the insulating part at least partially consists of a mixture of the treated and untreated granules.
  • a mixture of treated and untreated partial volumes makes it possible, depending on the mixing ratio of the volumes to one another, to achieve increased stability with respect to untreated material as changed electrical conductivity.
  • Treatment can be done by different methods.
  • a further advantageous embodiment may provide that the mixture is at least partially located on the surface of the insulating part.
  • a mixture is understood here to be the statistical distribution of different partial volumes within a total volume. The properties of the interconnecting partial volumes are not changed by the connection.
  • An arrangement of the mixture along the surface of the insulating material causes a particularly simple and direct influence on the electrical properties of the insulating part. It can also be provided that the entire Isolierstoffteil of a homogeneous mixture of treated and untreated partial volumes is formed. An arrangement of the mixture only in certain surface areas of the insulating part allows targeted control of the electrical behavior. For example, specific leakage current paths for deriving surface charges can be specifically designed on the insulating part.
  • the Kriechstrompfade can also enforce the interior of the insulating part and lead, for example, to electrodes.
  • the treated sub-volumes are embedded in the untreated sub-volumes.
  • Embedding the treated partial volumes in the untreated partial volumes makes it possible to produce insulating parts which, given a high mechanical strength, have favorable properties with regard to a changed electrical resistance, in particular on the surfaces of the insulating material part.
  • the untreated partial volumes are provided to ensure sufficient insulation resistance and mechanical strength of the insulating part.
  • the treated sub-volumes affect these properties only selectively and do not lead to a substantial weakening of the insulating part in terms of mechanical and dielectric properties.
  • the degree of embedding can be easily influenced.
  • a proportion of treated partial volumes which is reduced compared to untreated partial volumes results in sufficient embedding if the proportions are mixed. For a large proportion of treated partial volumes, for example, they should be well mixed in to ensure adequate embedding.
  • the proportion of treated partial volumes in the total volume of the Mixture may for example be 10, 20, 30, 40 or 50%.
  • the partial volumes consist of PTFE.
  • Polytetrafluoroethylene has a very high insulating capacity. Disadvantage of the very high insulation is that accumulate on the surface of a PTFE insulating material electrical charges, but these can not drain sufficiently due to the insulating power. This creates so vulnerable areas with an increased electric field strength, which can cause the occurrence of electrical flashovers or partial discharges.
  • Isolierstoffieri which are formed from PTFE and consist of treated and untreated sub-volumes, the risk of the occurrence of vulnerable areas is reduced.
  • Another object of the invention is to provide a simple and inexpensive method for producing an above-mentioned insulating part for a high-voltage electrical device.
  • the object is achieved in that treated partial volumes are mixed with untreated partial volumes and for the production of a Isolierstoffmaschines a shaping of the mixture takes place.
  • the mixture is sintered.
  • the partial volumes are in granular form.
  • the plurality of individual partial volumes or granules are to be connected by the sintering method in a suitable manner.
  • the insulating material nozzle 1 is used in high-voltage circuit breakers to influence the burning and extinguishing a switching arc and to direct the outflow of switching gases.
  • the insulating material nozzle 1 has a main body which has a continuous channel 2.
  • the main body is made of an insulating material, for example polytetrafluoroethylene (PTFE).
  • PTFE polytetrafluoroethylene
  • the channel 2 is designed substantially cylindrical at one of its ends. At the other end, the channel 2 widens funnel-shaped.
  • the surface of the insulating material is the first partially formed from a mixture of a first sub-volume 3 ( ⁇ ) and a second sub-volume 4 (O).
  • the first partial volume 3 is formed from a multiplicity of partial volumes (granules) which were exposed to high-energy radiation, for example alpha, beta or gamma radiation.
  • the second sub-volume 4 is untreated and also formed from a plurality of sub-volumes.
  • the treated partial volumes of the first partial volume 3 are embedded in the partial volumes of the second partial volume 4. That is, the partial volumes of the second sub-volume 4 are present in a larger amount than the sub-volumes of the first sub-volume 3.
  • other surface areas of the insulating material 1 with a mixture of treated sub-volumes and untreated sub-volumes can be formed.
  • the further surface areas may be arranged, for example, on the front side or on the shell side on the insulating material nozzle. In addition, it can furthermore be provided to produce the entire insulating material nozzle 1 from a mixture of treated and untreated partial volumes.
  • a method for producing an insulating nozzle, which consists entirely of a mixture of treated and untreated partial volumes, is in the FIG. 2 shown schematically.
  • the first sub-volume 3 is passed from a first collecting container 5 a coming past a beam gun 6 and irradiated with gamma radiation. By varying the time duration or the intensity of the radiation, the electrical properties can be influenced to a different extent.
  • the second subvolume 4 is supplied from a second sump 5b as well as the treated first subvolume 3 to a mixing device 7. In the mixing device 7, the required amounts of treated and untreated Partial volumes mixed together.
  • the mixture thus formed is connected in a mold 8, for example by a pressing process to form a shaped body.
  • the solid shaped body can be sintered to a solid shaped body.
  • an insulating nozzle formed from a first partial volume 3 and a second partial volume 4 is manufactured.
  • the Isolierstoffdüse can now be installed or subjected to further processing steps.
