Abstract
An electrode assembly for use in a vacuum interrupter is made by joining a first side of a substantially disk-shaped structure to an end of a substantially cylindrical coil segment, and joining an electrical contact to a second side of the disk-shaped structure. The disk-shaped structure has a higher resistivity than a resistivity of the coil segment.

A method for making an electrode assembly for use in a vacuum interrupter, the method comprising:
- forming an end portion at a perimeter of a substantially cylindrical coil segment;
- joining a first side of a substantially disk-shaped structure to the end portion of the substantially cylindrical coil segment by contacting a contiguous surface at the end portion of the substantially cylindrical coil segment directly to the first side of the disk-shaped structure such that the first side of the disk-shaped structure is flush with the contiguous surface of the substantially cylindrical coil segment end, the disk-shaped structure having a higher volume resistivity than a volume resistivity of the substantially cylindrical coil segment;
- and
- joining an electrical contact a second side of the disk-shaped structure such that, once joined, the electrical contact and the disk shape structure share an outer periphery and substantially all of a current that flows between the substantially cylindrical coil segment and the electrical contact flows through the end portion.

A method for making an electrode assembly for use in a vacuum interrupter, the method comprising:
- joining a first side of a substantially disk-shaped structure to an end portion of a substantially cylindrical coil segment, the disk-shaped structure having an outer diameter that is substantially equal to the outer diameter of the substantially cylindrical coil segment, the disk-shaped structure having a higher volume resistivity than a volume resistivity of the substantially cylindrical coil segment;
- and
- joining an electrical contact to a second side of the disk-shaped structure, the electrical contact having an outer diameter substantially equal to the outer diameters of the substantially cylindrical coil segment and the disk-shaped structure, such that substantially all current between the coil segment and the electrical contact travels through the end portion of the substantially cylindrical coil segment.
