Abstract
An electrode structure for a vacuum circuit breaker having a pair of separable spiral-formed electrodes includes an electrode rod, a contact fixed to the electrode rod, and a plurality of arc runners extending outward from the electrode rod in the radial direction thereof in a spiral fashion, each of the arc runners having an arc runner surface which are separated from adjacent ones by first channels. Each of the arc runner surfaces of the arc runners is provided with at least one second channel. The second channel is formed separately from the first channels so as to draw a leg of an electric arc on the first channels to the second channel.
