ABSTRACT:
A dielectric gas produced at the time of current interruption is exhausted into an exhaust structure 1 through an opening 8 formed on a fixed-side support member 6 combined with a fixed arcing contact 4. The exhaust structure 1 has an enlarged portion with a gas flow cross section formed at least before a position at 1/2 of the overall length of the exhaust structure 1 that is uniformly enlarged toward the rear of the exhaust structure 1 with respect to the joint between the exhaust tube 1 and the fixed-side support member 6. As a result, the gas is immediately exhausted into the exhaust structure 1 and the interelectrode insulation recovery performance is ensured.
