ABSTRACT:
The disclosed electrode assembly used with vacuum circuit interrupters has a disc-shaped electrode including four coil sections defined by four short radial slots extending radially inward at equal angular intervals from its periphery, four circumferential slots extending in a common circumferential direction from the inner ends of the radial slots and terminating short of the adjacent radial slots to define base ends of the coil sections between the ends of the circumferential slots, and a short-circuiting member including a connecting ring connected to an extremity of an electrode rod, and four L-shaped radial arms extending radially outward at equal angular intervals from the connecting ring and perpendicularly to the longitudinal axis of the ring with their free ends connected to the end portions of the coil sections remote from the base ends. The circumferential slots may have a radial slot extending radially inward toward the center of the electrode.
