Arcing contact tip and method for producing such an arcing contact tip or a comparable component

摘要

The arc withstanding electrodes in an electric circuit breaker for switching high voltages attain greater mechanical strength and improved arc withstanding capabilities by forming the arc withstanding electrodes of a carbon-fiber-reinforced-graphite material which material is constituted of a graphite matrix which is reinforced by carbon fibers embedded therein. A method for forming the carbon-fiber-reinforced-graphite of the arc electrodes and for affixing the arc electrodes to a metal carrier therefor includes the steps of employing a high-temperature solder based on copper and/or silver, containing at least one carbide-forming element such as, for example, Cr.
