Claim Text:
1. A switchgear, comprising: a plurality of switch units each including a fixed electrode and a movable electrode disposed opposite to the fixed electrode, the movable electrode being closed or opened with respect to the fixed electrode; an operating device configured to operate the movable electrode being closed or opened with respect to the fixed electrode of each of the switch units; and a conductor configured to electrically connect the switch units to each other, wherein the operating device is configured of one motive gear and two follower gears that intermittently operate with each other, wherein the motive gear has cogs around a portion of the circumference of the motive gear, wherein each of the two follower gears has cogs around a portion of the circumference of the follower gear, wherein the motive gear is driven by power of a motor transmitted via a power transmission mechanism, and a drive force of the motive gear is transmitted to a follower gear through engagement of the cogs of the motive gear with the cogs of a follower gear, and the drive force transmitted to each of the follower gears is transmitted to the respective movable electrodes via respective operating rods, which are connected to each of the respective follower gears, wherein in a condition that the cogs of the motive gear do not engage with the cogs of a follower gear, a state of the follower gear is fixed, wherein in a condition that the motive gear shifts from an initial position to a final position, the cogs of one of the two follower gears engages with the cogs of the motive gear, and the cogs of the other of the two follower gears engages with the cogs of the motive gear asynchronously with respect to the engagement of the cogs of the one following gear, thereby the switch units are driven while a time delay is produced.
