Abstract
In a hybrid type gas insulation switch gear apparatus, an enclosure includes a cylindrical branched portion branched from a cylindrical body so as to be inclined obliquely upward. An insulating gas is sealed therein. Insulating enclosures are mounted to the enclosure and the cylindrical branched portion, a disconnecting switch is arranged within the enclosure and electrically connected to the bushing. A circuit breaker is arranged within the insulating enclosure and electrically connected in series to the disconnecting switch. A current transformer is arranged on the cylindrical branched portion. A connecting conductor is arranged in between the circuit breaker and the disconnecting switch and an earth switch mounted to the enclosure, and an insulating member for supporting a primary electrode and the bushing conductor on the enclosure.
