METHOD FOR PRODUCING AN ARC-EROSION RESISTANT COATING AND CORRESPONDING SHIELD FOR VACUUM ARCING CHAMBERS

摘要

A method for producing an arc-erosion resistant coating provides a substrate material with an arc-erosion resistant layer by a cold-gas spraying method. The method can be used for producing an arc-erosion resistant coating in inner regions of vacuum interrupter chambers that are exposed to electric arcs. An exemplary vacuum interrupter chamber with a shield coated inside is disclosed for medium-voltage switchgear.
