Abstract
The invention disclosed a vacuum type electric circuit interrupter comprising a highly evacuated envelope which includes at least one metallic tube made of the magnetic material or the ferromagnetic material, a pair of relatively movable contacts disposed within said envelope in a location and means for eliminating the magnetodistortion of said metallic tube. This means comprises a magnetic flux generating member for supplying the magnetic flux to said metallic tube. The noise generated from the vacuum circuit interrupter is, accordingly, eliminated by means of a magnetic field applying member for applying previously the magnetic field to said metallic tube or by increasing the magnetic reluctance of the metallic tube.
