An operating device for a disconnector includes a drive unit, a Geneva mechanism, and a wire. The drive unit includes a forwardly and reversely rotatable motor serving as a drive source for driving a movable contactor of the disconnector, a power source supplying power to the motor, and a first pulley connected to a rotary shaft of the motor, and is disposed apart from the disconnector. The Geneva mechanism includes a second pulley that rotates in the same direction as the first pulley with the rotation of the first pulley, and a driven wheel that is intermittently driven while the second pulley rotates and that is provided with a rotary shaft connected to the movable contactor, and is attached to the disconnector apart from the drive unit. Further, as a flexible rotational force transmission member, a wire is stretched between the second pulley and the first pulley.

Gas insulated switching apparatus and switch

A current switch includes a blade-shaped movable contact that extends in a radial direction from a rotation center, and that reciprocates such that a free end of the movable contact draws a rotation locus, a fixed contact that includes a plurality of pairs of energizing contacts that come into and out of contact with the movable contact, a movable arcing contact that is provided on the movable contact, fixed arcing contacts that are provided on a pair of energizing contacts, and a pair of permanent magnets that are arranged within the pair of energizing contacts adjacent to the fixed arcing contacts.
