Definitions
- the invention relates to a vacuum interrupter chamber with an insulating ceramic wall, are arranged within the movable contact in vacuum and concentrically surrounded by a shield between the contact piece and switching chamber, according to the preamble of claim 1.
- Vacuum switching chambers are used in the low, medium and high voltage range. Within a vacuum are the contacts, the switching process itself takes place under a vacuum atmosphere. During the switching process, especially under short-circuit conditions, the goal is to extinguish the arc as quickly as possible. Said arc as such is a high-energy plasma stream of the evaporation processes generated within the vacuum interrupter chamber.
- no metallic layer formed inside on the ceramic wall material of the vacuum interrupter chamber thus reducing the insulation capacity of the unit shielding components of thinner-walled metallic materials are usually introduced within the vacuum interrupter chamber, in the vicinity of the contact gap between the contact pieces and the insulation are arranged.
- the required high erosion resistance can not be met by the screen materials commonly used in this form, or can only be achieved imperfectly.
- the invention is therefore based on the object, at the structurally resulting within the vacuum switching chamber edges or fillets of the subcomponents used to increase the dielectric strength. In the area of the contact pieces, the erosion resistance of the screen should be improved.
- edges or fillets of the screens should thus be coated with a material of high dielectric strength. This is achieved by a high electron work function and / or a mechanically high hardness. The dielectric strength of the arrangement or device, in particular on the screen edges, is increased. It can still be seen that on the so-called
- Middle screen a corresponding edge board is arranged, which is guided to the outside and a screen control, that is, a corresponding control of the center potential is possible.
- the layer on the components can be made relatively thin.
- Coatings may consist of the abovementioned elements, mixtures and / or alloys in said form, for example TiN, TiNMI 2 O 3 , TiCN, TiAIN, C at least partly in diamond structure or also in a mixture with tungsten, hard metal coatings of WC and the like cermet.
- These areas shown in the following drawing with XY consist of these mentioned material composites, wherein it is not excluded that these coatings can also be applied in the areas XXX and vice versa.
- the layer may also be formed by nanoparticles, which may have correspondingly optimal properties due to their structure.
- refractory or refractory metals are used on the surface of a component, which may be in the form of nanoparticles or as a layer, i. as a closed layer on the support, here the screen component partially or completely applied.
- the materials used include the elements: tungsten, chromium, molybdenum, vanadium, titanium, tantalum and carbon.
- the above-mentioned elements for the coating are selected for the areas denoted by XXX.
- the coatings may consist of mixtures and / or alloys in the stated form, for example TiN, TiNMI 2 O 3 , TiCN, TiAIN, C in diamond structure, hard metal coatings of WC, and cermets. These areas shown in the following drawing with XY consist of these material composites.
- the application of these particles or layers can take place via a chemical route.
- Another possibility for applying a layer to a component is the immersion / coating / spraying or a physical vapor deposition (PVD) or a chemical vapor deposition (CVD) process by sputtering / vapor deposition or chemical surface reaction.
- PVD physical vapor deposition
- CVD chemical vapor deposition
- the switching contacts 5 are arranged.
- a switching contact fixed 8 is about a bellows 3 this movably 1 arranged within the vacuum interrupter chamber.
- two movable contacts can be used, each contact piece is driven accordingly and guided over a metal bellows with a push rod to the outside.
- the two metallic conductors 1, 8 are electrically separated from each other by an insulator 6.
- the cover components 2 shown in this arrangement take over the connection between the insulator 6 and the bellows on one side and the conductor 8 on the other.
- shieldings 4, 7 are arranged here in this sectional view, essentially here a center screen 4 can be seen, which is placed in the area around the actual contact point.
- the center screen is coated with the corresponding material XXX or the material composite XY, in accordance with the above-mentioned materials or elements, alloys, etc.
- Umbrella can be prevented, and on the other hand, the dielectric strength of the device or device is increased in particular at the screen edges. It can also be seen that on the so-called center screen 4, a corresponding edge board is arranged, which is guided to the outside and a screen control, that is, a corresponding control of the center potential is possible.
