Latest Patents

Muller's latest patents include "Contact pieces for vacuum switchgear" and "Method for the manufacture of contact pieces for vacuum switchgear." The first patent addresses the design of contact pieces that utilize a base material with additives of readily vaporizable components. This design aims to produce a sufficiently conductive switch path during the switch-off process, ensuring overvoltage-free switching behavior. The additives are concentrated in a firmly adhering layer that covers the switching surface of the contact piece. Various manufacturing methods are proposed, including direct fusing of the additives, fusing separate applications in different forms, or vapor deposition on the contact piece body.

The second patent focuses on a method for producing copper-chromium fusion alloys as contact material. This method ensures a chromium content of at least 25% and at most 60% by mass, resulting in a homogeneous macrostructure without lattice defects. The process involves superheating the starting material to at least 2000 degrees Celsius, followed by controlled cooling to prevent primary chromium precipitation or segregation. These innovations are particularly relevant for vacuum power switches that handle breaking currents exceeding 10kA.
