Abstract:
In a gas circuit breaker, arc-extinguishing gas is filled in a container. A movable portion housed in the container includes a movable arc contact. The movable portion includes a pressure accumulator that increases pressure of an arc-extinguishing gas. An opposing portion housed in the container includes an opposing arc contact, an exhaust pipe, and a shielding portion. The shielding portion includes a first shielding wall intersecting with an axial direction of the pipe and a second shielding wall having a cylindrical shape extending from the first shielding wall toward the movable portion along the axial direction of the pipe. The second shielding wall includes through-holes. Lengths of the respective through-holes along the axial direction are from 18 millimeter's to 55 millimeters inclusive. An arc-extinguishing gas whose pressure has been increased in the pressure accumulator flows into a space to extinguish arc discharge, and flows into the second shielding wall.

Claim (Index 2):
The gas circuit breaker according to  claim 1 , wherein\n the second shielding wall is provided with the n through-holes (n is a natural number of 3 or more) with a space therebetween along the axial direction, a ratio of an opening area of the through-hole closest to the first shielding wall, of the n through-holes, to a total of respective opening areas of the n through-holes is 0.45\u00d73/n\u00b10.05, a ratio of an opening area of the through-hole closest to the opposing arc contact, of the n through-holes, to the total of respective opening areas is 0.32\u00d73/n\u00b10.05, and a ratio of an opening area of the through-hole provided between the through-hole closest to the first shielding wall and the through-hole closest to the opposing arc contact, of the n through-holes, to the total of respective opening areas is (1\u22122.31/n)/(n\u22122)\u00b10.05.
