Definitions
- the invention relates to a vacuum interrupter with shielding, according to the preamble of patent claim 1.
- the invention relates to vacuum interrupters for medium-voltage switching devices. It is known to equip vacuum interrupters with a burn-off-resistant screen for a large number of short-circuit current cutouts with a compact design.
- the vacuum interrupters are used in low, medium and high voltage technology.
- the said shields for vacuum interrupters are predominantly made of copper and / or stainless steel.
- the compact design of the vacuum interrupter has a high thermal load on the shielding surrounding the switching system. The load results from the plasma radiation from the metal vapor arc and, in the case of a grinding arc, through direct contact with the shield.
- the shielding surrounding the contact system is reinforced by the use of a copper-chrome cylinder tube section (composite material - copper-chrome). Shields made of the composite material CuCr with chromium concentrations greater than 15% by weight are known. Furthermore, for reasons of cost, efforts are being made to dispense with an additional screen made of CuCr.
- Another method is plasma spraying, i.e. a thermal process for applying a copper chrome layer.
- the plasma spraying is advantageously carried out in an inert gas atmosphere due to the strong gettering effect of the chromium.
- an increased gas content in the sprayed-on layer is inevitable
- MLC vacuum interrupter contact piece
- the invention is therefore based on the object of increasing the number of possible short-circuit current switch-offs.
- the object is achieved by a vacuum interrupter of the generic type according to the invention by the characterizing features of claim 1.
- a ready-to-install screen made of a low-alloy copper material, e.g. Copper made with chrome and / or zircon.
- the chromium concentration is in the range between> 0 and 5% by weight.
- the screen is preferably made from a commercially available alloy CuCrZr (2.1293) with the composition Cr 0.8, Zr 0.08 and the rest copper.
- the entire screen consists of a low-alloy and therefore erosion-resistant alloy, which consists of copper with a chromium and / or zicon addition between 0 and 10% by weight.
- the screen consists of a CuCrZr alloy with the composition Cr 0.8 Zr 0.08 and the rest copper or a CuCrAgFeTiSi alloy.
- the screen can subsequently be manufactured using a standard shaping process (e.g. deep drawing). This allows an additional operation, e.g. avoid the creation of an erosion-resistant and additional screen part or an additional coating of a component.
- a standard shaping process e.g. deep drawing
- the shielding of the vacuum interrupter chamber is made only in part from the alloy.
- a screen coating is additionally provided in which further elements can be alloyed or contained in the copper, namely tungsten and / or molybdenum and / or platinum and / or zirconium and / or yttrium and / or palladium and / or silver.
- the figure shows a screen part that surrounds a contact system.
- the shield component 10 can, as shown, be part of a shield or as
