Abstract
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.
