Abstract

PURPOSE: To completely protect the gas gap of an opened circuit breaker from plasma cloud by separating an outside chamber from a chamber of inside arc contacts by a shielding cylinder, when a short-circuit current is interrupted, so as to be situated at the outside of a switching section at all positions and processes. CONSTITUTION: When a short-circuit current is interrupted, a shielding cylinder 21 completely separates the outside chamber 19 of outside contact pieces 4, 5 from the chamber of inside arc contacts 12, 13. Further, the repelling force between soft iron rings 23, 26 on the occurrence of a short circuit drastically accelerates the movable soft iron ring 23, together with the shielding cylinder to follow an insulating material nozzle 11 which is moved so as to separate. The shielding cylinder 21 moves and is brought into contact with an elastic cushion 27, arranged in the stepped part of the nozzle 11. Thus, the chamber filled with arc plasma is surrounded by the shielding cylinder 21 and separated from the outside chamber 19, for housing a cold gas which is not contaminated.
