Definitions
- the invention relates to a high-frequency high-voltage current conductor device with an electrical conductor which is designed for operation with a high-frequency high voltage in relation to a gaseous environment and / or in relation to a mass body.
- High voltage means voltages at which an ionization of the gaseous environment on the electrical conductor or a contact device contacting it would set in. This voltage cannot be limited by a specific value, as it depends very strongly on the gaseous environment, for example on pressure, temperature, gas composition, and also on the geometry of the electrical conductor and the electrically conductive devices in contact with it, especially if these are designed in such a way that they lead to higher fields. These can be points, corners and / or edges, for example. Such electrically conductive devices with edges occur, for example, in fastening devices for the electrical conductor.
- ionization can occur, especially if the high field strength occurs in a gaseous environment, for example air.
- This phenomenon has long been known and, for example, in wikipedia.org, Paschen's law fhttps: //de.wikipe- dia.org/wiki/Paschen-Gesetz) or dielectric strength fhttos: //de.wikioedia.ora / wiki / Sleep tightness) is described.
- Paschen ionization occurs, for example in ambient air, from field strengths of typically 3 kV / mm. Paschen bases this on a homogeneous field. In reality, however, one often has other geometrical conditions.
- the field is often not homogeneous because the electrical conductor with a high voltage has a shape that can have corners and edges. Very high field strengths, often not easily determinable, occur at these. On the other hand, especially in the case of a high-frequency field, a very strong field can also occur against the environment.
- high frequency means frequencies greater than 1 MHz. Ionization occurs on conductors not only, but especially at such frequencies, even if the next reference potential body, ie electrically conductive body that is connected to reference ground, is very far away. This has to do with the fact that with such high-frequency vibrations, energy can also propagate in the gaseous environment without it is ionized. This creates a potential in the environment that is close to the ground reference. Discharges can occur at this ambient potential.
- the object of the present invention is to avoid such ionizations on the electrical conductor or on electrically conductive devices attached to it.
- a high-frequency high-voltage conductor device with an electrical conductor which is designed for operation with a high-frequency high voltage in relation to a gaseous environment and / or a mass body, the conductor touching an electrically conductive contact device at at least one point , which is arranged on an electrically insulating holder, wherein an electrically conductive Feldverottisan order is arranged on the electrically conductive contact device, which is electrically conductive to the contact device is the.
- the field distribution arrangement can be arranged at least partially in the interior of the holder.
- the electrical conductor can be arranged at a distance from the mass body.
- the electrical conductor can be arranged at least in sections in a gaseous environment, in particular without insulation. At least in sections, the electrical conductor with its electrically conductive material can therefore be exposed to a gas, in particular air.
- the electrically conductive field distribution arrangement can be arranged between the mass body and the electrically conductive contact device.
- the field strengths at the electrically conductive contact device can thus be reduced. This can reduce the risk of ionization.
- the electrically conductive field distribution arrangement can alternatively or additionally be arranged between the gaseous environment and the electrically conductive Kunststoffeinrich device.
- the field strengths at the electrically conductive contact device can thus be reduced. This can reduce the risk of ionization.
- high frequency is understood to mean frequencies> 1 MHz and ⁇ 500 MHz.
- high voltage is understood to be a voltage which is large enough to lead to an ionizing field strength on the high-frequency, high-voltage current conductor device. Since, as mentioned above, this voltage depends on a large number of environment variables, an exact value cannot be given. However, it can be said that with peak voltages> 1 kV these phenomena occur with a very high probability. For this reason, a device that is designed for such a voltage and / or in which such a high voltage develops during operation is considered a high-voltage conductor device for the purposes of this disclosure.
- This high voltage is measured against a reference potential, for example an earth.
- the power and amperage play a subordinate role for this invention.

- the field distribution arrangement can be designed to be planar, at least in sections, in particular completely. In this way, the device according to the invention can be constructed in a particularly space-saving manner.
- the field distribution arrangement can have an edge and / or tip with a thickness of ⁇ 0.25 mm, in particular a thickness of 35 ⁇ m.
- the edge and / or tip can preferably be arranged completely in the interior of the electrically insulating holder.
- a very high field strength of 2 kV / mm or greater can develop at the edge and / or tip. If the edge and / or tip is arranged in the interior of the electrically insulating holder, the electrically insulating holder can be designed in such a way that such a high field strength does not lead to flashovers.
- a high-frequency, high-voltage electrical conductor can be arranged in the vicinity of one or more mass bodies in a space-saving, stable and cost-effective and reliable manner and also easy to produce.

- the device can be designed so that it is located on the edge and / or tip of the contact device Form fields that are smaller than the ionization field strength, especially in a gaseous environment, especially air, smaller than 3 kV / mm. In this way, the risk of a rollover at the edge and / or the tip of the contact device can be reduced even with a very thin edge and / or tip.
