MANUFACTURING METHOD OF VACUUM ARC-EXTINGUISHING CHAMBERS (VEC) Russian patent published in 2014 - IPC B23K1/08 B23K31/02 H01H33/66 

Abstract RU 2532627 C2

FIELD: metallurgy.

SUBSTANCE: invention can be used at manufacture of vacuum arc-extinguishing chambers (VEC) for vacuum circuit breakers for the rated voltage of 110 kV and higher. Assembly of portions pre-soldered with the first solder metal and having one or more non-soldered seams between them is performed. The second solder metal is laid with lower fusion temperature than that of the first solder metal. Sealing of the VEC made in a vacuum furnace is performed. Gas is pumped out of the furnace volume with additional exposure at the temperature of not more than 100°C with duration that is sufficient for removal of gas from inner volume of the VEC being made through unsoldered seams. Heating is performed to the degassing temperature of VEC portions at the rate chosen from a condition providing the pressure inside VEC of not more than 10-2 Pa with exposure at the same temperature. Short-time heating and exposure is performed at fusion temperature of the second solder metal. After heating is completed, seams are sealed. The method involves non-stem pumping-out and sealing.

EFFECT: method provides for a possibility of group treatment of vacuum arc-extinguishing chambers of a large size and combination of assembly, pumping-out and sealing operations.
