Definitions
- the invention relates to an insulating material part for an electrical high-voltage device, in particular for a high-voltage circuit breaker, the insulating material part having at least a partial volume whose conductivity has been changed by a treatment, and to a method for producing such an insulating material part - les.
- An insulating material part is known, for example, from patent specification DE 198 26 202 C2.
- these areas of the finished insulating part are irradiated with beta or gamma radiation.
- the treatment with high-energy radiation influences the particle bonds of the insulating material.
- the material becomes brittle as a result of breaking the particle bonds. This reduces the mechanical strength.
- the insulating material parts treated in this way must be dimensioned accordingly generously.
- the object of the invention is to design an insulating material part with at least one treated partial volume in such a way that the insulating material part has improved mechanical strength.
- the object is achieved according to the invention in the case of an insulating material part of the type mentioned at the outset in that the insulating material part at least partially consists of a mixture of treated partial volumes and untreated partial volumes.
- 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 an electrical conductivity that is different from that of untreated material.
- Treatment can be carried out using various methods. It is thus possible to treat partial volumes mechanically, chemically or, for example, with high-energy radiation such as alpha, beta or gamma radiation.
- a further advantageous embodiment can provide that the mixture lies at least partially on the surface of the insulating part.
- a mixture is understood here to mean the statistical distribution of different partial volumes within a total volume. The properties of the interconnecting partial volumes are not changed by the connection.
- Influencing the electrical properties of the insulating part It can also be provided that the entire insulating material part is treated from a homogeneous mixture and untreated partial volumes is formed. An arrangement of the mixture only in certain surface areas of the insulating part allows a targeted control of the electrical behavior. For example, certain leakage current paths for deriving surface charges can be specifically constructed on the insulating part. The leakage current paths can also penetrate the interior of the insulating part and, for example, lead to electrodes.
- the treated partial volumes are embedded in the untreated partial volumes.
- Embedding the treated partial volumes in the untreated partial volumes makes it possible to manufacture insulating material parts which, with 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 strength and mechanical strength of the insulating material part.
- the treated partial volumes only influence these properties selectively and do not lead to a substantial weakening of the insulating material part with regard to mechanical and dielectric properties.
- the degree of embedding can be easily influenced by choosing the mixing ratio of untreated and treated partial volumes. A reduced proportion of treated partial volumes compared to untreated partial volumes results in sufficient embedding when the proportions are mixed. With a big one
- Proportion of treated partial volumes must be mixed in well, for example, to ensure adequate embedding.
- the share of treated partial volumes in the total volume of the Mixtures can be, for example, 10, 20, 30, 40 or 50%.
- the partial volumes consist of PTFE.
- Polytetrafluoroethylene has a very high insulating capacity.
- the disadvantage of the very high insulating capacity is that electrical charges collect on the surface of a PTFE insulating material part, but due to the insulating capacity they cannot flow away to a sufficient extent. This creates endangered areas with an increased electrical field strength, which can cause electrical flashovers or partial discharges to occur.
- Another object of the invention is to provide a simple and inexpensive method for producing an above-mentioned insulating part for an electrical high-voltage device.
- the object is achieved in that treated partial volumes are mixed with untreated partial volumes and the mixture is shaped to produce an insulating part.
- the mixture is sintered.
- the partial volumes are often in granular form.
- the large number of individual partial volumes or granules can be connected in a suitable manner by the sintering process.
- Figure 2 is a schematic representation of a method for producing an insulating nozzle.
- An insulating material nozzle 1 shown in FIG. 1 is used in high-voltage circuit breakers in order to influence the burning and extinguishing of a switching arc and to direct the outflow of switching gases.
- the insulating material nozzle 1 has a base body which has a continuous channel 2.
- the base body is made of an insulating material, for example polytetrafluoroethylene (PTFE).
- the channel 2 is essentially cylindrical in shape at one of its ends. At the other end, channel 2 widens in a funnel shape.
- the surface of the insulating material nozzle 1 is at the funnel-shaped end of the channel 2 partially formed from a mixture of a first partial volume 3 ( ⁇ g>) and a second partial volume 4 (O).
- the first partial volume 3 is formed from a large number of partial volumes (granules) which have been exposed to high-energy radiation, for example alpha, beta or gamma radiation.
- the second partial volume 4 is untreated and is also formed from a large number of partial volumes.
- the treated partial volumes of the first partial volume 3 are embedded in the partial volumes of the second partial volume 4. This means that the partial volumes of the second partial volume 4 are present in a larger amount than the partial volumes of the first partial volume 3.
- further surface areas of the insulating material nozzle 1 can also be formed with a mixture of treated partial volumes and untreated partial volumes.
- the further surface areas can be arranged, for example, on the end face or on the shell side of the insulating material nozzle.
- a method for producing an insulating material nozzle which consists entirely of a mixture of treated and untreated partial volumes, is shown schematically in FIG.
- the first partial volume 3 is guided past a radiation cannon 6 and irradiated with gamma radiation.
- the electrical properties can be influenced to a different extent by varying the duration or the intensity of the radiation.
- the second partial volume 4 coming from a second collecting container 5b, is fed to a mixing device 7, as is the treated first partial volume 3. In the mixing device 7, the required amounts of treated and unhindered mixed partial volumes mixed together.
- an insulating material nozzle is made up of a first partial volume 3 and a second partial volume 4. The insulating material nozzle can now be installed or subjected to further processing steps.
- This process can also be used to produce insulating bodies which only partially have a mixture of treated and untreated partial volumes.
