An enclosure for a circuit breaker that includes a particle trap that is integrated into at least one foot of the enclosure. The enclosure can be configured to house a circuit interrupter and seal a dielectric insulating medium within an interior region of the enclosure. The particle trap can include an opening that extends through at least an inner side of a wall of the enclosure and into an adjacent foot such that the opening is in fluid communication with the interior region of the enclosure. Additionally, the opening of the particle trap can radially extend within both the wall of the enclosure and the foot between a first side and a second side of the particle trap.

There is a gas circuit breaker that can reduce deterioration in insulation performance and current breaking performance due to unnecessary gas generated from arc-extinguishing gas sprayed to an arc. The gas circuit breaker includes a sealed container 8 in which the arc-extinguishing gas is enclosed, a first fixed contactor portion 2 fixed to the sealed container 8, a second fixed contactor portion 4 fixed to the sealed container 8, and a movable contactor portion 3 which moves between the first fixed contactor portion 2 and the second fixed contactor portion 4, to conduct and break current between the first fixed contactor portion 2 and the second fixed contactor portion 4, in which an arc generated between a fixed arc contactor 21 provided to the first fixed contactor portion 2 and a movable arc contactor 31 provided to the movable contactor portion 3 at a time of current breaking action is extinguished by spraying the arc-extinguishing gas, the gas circuit breaker includes a gas chamber 5 configured to accumulate the unnecessary gas generated from the arc-extinguishing gas sprayed to the arc, the sealed container 8 is formed by joining ends of the two hollow truncated cone portions 82 and 83, each having a large opening diameter, with the cylindrical portion 82 therebetween, and the gas chamber 5 is formed inside the cylindrical portion 81 forming the sealed container 8.

A method monitors gases produced in an insulating medium circuit. The insulating medium circuit is in contact with a transition resistor of an on-load tap-changer. The method includes: ascertaining a time profile of a resistor temperature of the transition resistor during a loading time period; and determining at least one characteristic value for characterizing the gases produced based upon the time profile of the resistor temperature.
