    摘要: The disclosed concept pertains to vacuum interrupters and arc-resistant shields. The arc-resistant shields are positioned in between a ceramic insulator. Each end of the arc-resistant shield is hermetically sealed to the ceramic insulator. The arc-resistant shield includes an outer surface and an inner surface. The inner surface includes an arc-resistant material. Disposed within the arc-resistant shield is a pair of electrode assemblies which are separable to establish arcing. In certain embodiments, the arc-resistant material is copper-chromium alloy.

    摘要: The disclosed concept pertains to alloy compositions, methods and arc-resistant shields composed of the alloy compositions. The arc-resistant shields are positioned in vacuum interrupter chambers and demonstrate resistance to arc damage and ability to hold off high voltages after arcing, while providing a lower cost alternative to traditional alloy compositions used for producing arc-resistant shields. In certain embodiments, the alloy compositions include copper and/or an element chemically compatible to copper and another component, such as but not limited to, iron, stainless steel, niobium, molybdenum, vanadium, tungsten carbide, chromium carbide, vanadium carbide and chromium, and alloys and mixtures thereof.
