Break-away element for electrical capacitor

In an electrical capacitor having a housing, an improved over-pressure break-away element composed of a malleably deformed wire having a rated break location with a smooth surface and a gradual continuous transition from a cross section of said wire to a cross section of said break location.

A method for manufacturing a break-away element of an electrical capacitor, comprising the steps of: introducing a malleably deformable break-away wire of a first cross section between turning rollers whose spacing corresponds to a desired remaining cross section of a rated break location, and compressing said breakaway wire between said turning rollers to achieve a portion of said wire with a gradual continuous transition of cross section to a second cross section corresponding to said cross section of said rated break location, said portion of said wire having a uniformly reduced smooth surface.

A method of manufacturing a break-away element for an electrical capacitor, comprising the steps of: conduct a break-away wire of a first cross section through closing grinding wheels to form a break-away region of a reduced second cross section and transition regions on either side of said break-away region with smooth surfaces and a gradual continuous change in cross section between said first and second cross section.

A break-away element for an electrical capacitor, comprising: a malleably deformable wire of a first cross section; a break location at a location along said wire, said break location being of a second cross section that is smaller than said first cross section; and at least one transition region between said wire of said first cross section and said break location of said second cross section, at least one transition region being of continuously gradually changing cross section and having a uniformly reduced smooth surface.
