Definitions
- the invention relates to an insulating component of a high-voltage switching device, in particular for use in gas-insulated systems.
- Such a component is known for example from DE-PS 26 26 855.
- Such insulating material components are used, for example, in electrical high-voltage switches, in particular in high-voltage circuit breakers, as spacers or as nozzles for guiding insulating gas.
- encapsulated high-voltage switchgear such components are used, for example, as supports for busbar conductors or as bushings.
- a weakly conductive fabric for dissipating surface charges is embedded in the area of the surface of the component.
- the present invention is based on the object of creating an insulating component of the type mentioned at the outset which can withstand high dielectric loads with little production outlay.
- the surface of the component has sharp-edged grooves or webs with a profile depth of at least 100 ⁇ m at least in a region that is particularly stressed in terms of dielectric.
- An advantageous embodiment of the invention provides that at least one region of the surface that is particularly stressed by dielectric has a profile depth of at least 200 ⁇ m.
- this has sharp-edged elevations or recesses in the area of its surface due to the surface structure.
- This structure leads to an improved dielectric strength, in that high electrical field strengths arise at the tips and edges, which lead to the emission of surface charges and thus limit the potential of surface charges.
- An advantageous embodiment of the invention provides that the grooves or webs are produced by machining.
- the component can be reworked, for example by casting, sintering or extrusion, in the region which is particularly stressed by dielectric, by milling or turning.
- a depth of the grooves of more than 200 ⁇ m has proven to be particularly advantageous.
- the grooves can advantageously be arranged concentrically to one another or in the form of a spiral.
- the grooves or webs can advantageously be rectangular or sawtooth-shaped in cross section. Such a profile is easy to turn or mill.
- the invention also relates to a method for producing an insulating component for high-voltage devices, in which the component, after being formed, is provided with grooves by machining or at least in a region which is subject to particularly high dielectric stress, or is machined so that there are webs stay.
- the component it is also conceivable for the component to be produced in a casting process and for the casting mold to have grooves or webs in the region which is particularly stressed in dielectric terms and which produce corresponding complementary structures on the surface of the component.
- An insulating component is often present after shaping with a uniform surface quality and can then be reworked in the regions of its surface which are particularly stressed by the method according to the invention.
- an area of the surface to be provided with unevenness using an embossing tool.
- FIG. 1 shows schematically in longitudinal section an isolator nozzle circuit breaker with an isolator nozzle made of PTFE
- FIG. 2 shows a plan view of the isolator nozzle
- FIG. 3 shows schematically in longitudinal section a double nozzle circuit breaker with a compression cylinder made of an insulating material.
- the figure shows a circuit breaker in the ON state.
- the insulating nozzle 9 which is made of PTFE, also runs off the fixed arcing contact 2.
- the insulating material nozzle 9 is connected to the compression cylinder 5 in the area of the continuous current contact 3.
- the end face 10 of the insulating material nozzle is subjected to a particularly high dielectric stress due to the electrical field between the arcing contact pieces 1, 2.
- essentially concentric grooves for example, by turning the end face a spiral groove
- a width and depth of approximately 1 mm are introduced by machining, an approximately 1 mm wide web with a rectangular cross section being arranged between the grooves .
- An arrangement according to the invention proves to be dielectrically safer than a component correspondingly equipped with a surface quality that is continuously better due to production.
- FIG. 3 shows a double nozzle switch with two fixed nozzle-shaped contact pieces 13, 14, which are conductively connected to one another by a bridging switch piece 15 in the on state.
- a compression device is provided for an extinguishing gas, consisting of a stationary compression piston 16 and a movable compression cylinder 17.
- the compression cylinder In the switched-off state, the compression cylinder is withdrawn to such an extent that its bottom 18 is located in the separating distance between the fixed contact pieces 13, 14 and is exposed there to the electric field.
- the bottom 18 has, on its side facing the switching path in the switched-off state, a cross-sectionally sawtooth-shaped structure which enables surface layers to be removed.
