An enclosure of a circuit breaker that includes an interior region and a pass-through. The interior region can be sized to house a circuit interrupter and a dielectric insulating medium. The pass-through can include a pathway having a first open end and a second open end, the first and second open ends being in direct fluid communication with each other through the pathway. The first and second open ends can be secured to the enclosure such that the pass-through is integral to the enclosure, such as, for example, being part of a monolithic structure or constructed to form a unitary body. Additionally, the pathway may not be in direct fluid communication with the interior region of the enclosure. Further, the pass-through can be offset from, or extend directly into, the interior region of the enclosure.

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.

A gas insulation apparatus has a sealed container, an insulation gas, a high-voltage portion, and a removal material. The insulation gas has CO.sub.2 and O.sub.2 filling the sealed container as main components. The high-voltage portion is stored in the sealed container. The removal material reduces concentrations of HF, CO, and O.sub.3 in the insulation gas.

The present invention concerns a gas insulated circuit breaker system. The system comprises a base station, an insulating column, a transition elbow and an interrupting chamber. With the placement of motion transferring mechanisms in the base station and the transition elbow, the system allows the opening and closing of the integrated circuit breaker within the interrupting chamber in a compact and efficient configuration from a link to an external control module in the base station.

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.
