ABSTRACT:
A surge arrester with a parallel-connected improved spark gap structure has a flanged ring connected to one of the two electrodes of the surge arrester which forms the first electrode of the spark gap structure, an axially aligned insulator disc having recesses therein seated on the flanged ring, and an annular metal contact seated on the opposite side of the insulator ring forming the second electrode of the spark gap structure through the recesses in the insulating ring has the improvements of the metal contact forming the second electrode of the spark gap being an annular cup having a base seated against the insulator ring and a conical wall connected via contact springs with the other electrode of the surge arrester, and the base of the annular cup has projections in registry with the insulator ring recesses extending a distance therein such that the spark gap is formed between the flanged ring and the highest elevation of the projections. The spark gap serves as a back up to a fail-safe device which would normally permanently short the surge arrester to ground after an extended discharge, which spark gap is resistant to conductive deposits being formed thereon.
