METHOD FOR MAKING CONTACTS OF VACUUM ARC-EXTINGUISHING CHAMBER Russian patent published in 2003 - IPC

Abstract RU 2200210 C2

FIELD: electrical engineering, namely processes for making contacts of vacuum arc-extinguishing chamber. SUBSTANCE: method comprises steps of preliminarily preparing powder mixture consisting at least of two powder components - electrically conducting and heat resistant; placing blank of material with high electrical conductance in vacuum chamber and applying coating of powder mixture by electron beam welding. EFFECT: enhanced quality of contacts due to using of finely dispersed and gas-free contact material. 1 tbl
