摘要： In an insulated type switchgear device in which a pair of arc electrodes are separably disposed in an opposing manner in a vacuum tube, and having a movable conductor extending from a back face of a movable one of the arc electrodes to the outside of the vacuum tube, the pair of arc electrodes are designed to be separated through a rotation of the movable conductor around a predetermined main axis. The movable arc electrode is structured in such a manner that an electrode center of the movable arc electrode, when the movable arc electrode is brought into its circuit breaking position, is to be located near a center axis of the stationary arc electrode, whereby the center of the movable arc electrode is offset from the center axis of the stationary arc electrode when the pair of arc electrodes are brought into their circuit making position, and whereby an insulation type switchgear device is provided which suppresses a possible offsetting of arc electrodes at a circuit breaking position thereof, improves circuit breaking performance thereof, and permits downsizing thereof.

摘要： A transformer apparatus whose transformer and a plurality of circuit-breakers are individually accommodated in a plurality of different casings. The casings are stacked one above each other in a plurality of stages with gaps between two subsequent casings and between the casing in the lowermost stage and the floor surface on which the apparatus is mounted. When a specific casing among the plurality of casings which is in an intermediate stage is to be dismounted, support columns are disposed on the outside of the specific casing with their respective ends inserted into the relevant gaps in such a manner that the support columns support the upper subsequent casing, thereby enabling the intermediate casing to be dismounted and remounted.
