Abstract

The invention provides a gas insulated switchgear, and a method for detecting are damage in part used in a gas insulated switchgear, which detect directly when an electric contact or a peripheral part reaches an initially set wear limit. An insulating nozzle of a circuit beaker contains a making substance that releases a gaseous substance inside a circuit breaker gas container as a result of wear by an arc. For ensuring heat resistance and insulation properties, the insulating nozzle is ordinarily formed of the ordinarily used fluororesin having uniformly mixed therein, as the marking substance, a chlorine-containing resin which has excellent heat resistance and insulation properties such as polyvinylidene chloride.
