Summary:In an insulated type switchgear device in which a pair of arc electrodes (4) and (5) are separably disposed in an opposing manner in a vacuum tube (30) and a movable conductor (3) extending from a back face of a movable arc electrode (5) to an outside from the vacuum tube (30) and the pair of arc electrodes (4) and (5) are designed to be separated through a rotation of the movable conductor (3) around a predetermined main axis (15), the movable arc electrode (5) is structured in such a manner that an electrode center of the movable arc electrode (5), when the movable arc electrode (5) is brought into its circuit breaking position (Y2), is to be located near a center axis of the stationary arc electrode (4), thereby the center of the movable arc electrode (5) is offset from the center axis of the stationary arc electrode (4) when the pair of arc electrodes (4) and (5) are brought into their circuit making position (Y1), whereby an insulation type switchgear device is provided which suppresses a possible offsetting of arc electrodes at circuit breaking position thereof, improves circuit breaking performance thereof and permits a down sizing thereof.
