Surge arrester gap assembly
First Claim
Patent Images
1. A spark gap assembly for a surge voltage arrester comprising:
- a single electrode having a flat projection surface thereon for defining an extended arcing surface and a pair of flat contact surfaces thereon, one of said contact surfaces, including high-electrical resistive means for limiting current flow to said one surface;
a double electrode structure having a first pair of opposing flat contact surfaces on one side and a second pair of flat opposing contact surfaces on another side thereof, a pair of flat projected surfaces for defining arcing surfaces, said first pair of contact surfaces being electrically coupled together; and
a disc of electrically insulating material separating said single electrode structure and said double electrode structure and providing arc quenching means therebetween said electrodes.
