It is. Therefore, for example, when a disconnector is installed on the primary side of a transformer and used for switching the exciting current of the transformer, the current switching capability may be insufficient. In order for both the disconnecting switch and the earthing switch to have a sufficient current switching capability, a high-speed operation of several meters per second is required, and there is a problem that the required high-speed operation cannot be obtained with the conventional device. An object of the present invention is to provide an inexpensive switchgear operating device that can achieve a high-speed opening / closing operation, has a simple configuration, and is inexpensive.

As a result, the sub shaft 41 rotates at high speed in the clockwise direction after leaving the sub hoisting clutch 45, the sub drive lever 50 rotates at high speed in the clockwise direction via the sub drive clutch 51, and the main lever 13 rotates at high speed in the counterclockwise direction. , The pin 54 is in the final lower position 21
, The center pin 17 moves to the ground switch on position 22, and the connecting device 16 moves at high speed, and operates at a high speed from the off state to the ground switch on state. The sub-drive lever 51 is stopped at a predetermined position by a stopper (not shown) during high-speed rotation. Next, from the state where the grounding switch is turned on to the state where the grounding switch is turned off, the lower motor 10 rotates at a high speed by the reverse rotation of the above operation.

ができ、しかも構成が簡単で安価である。[Effects of the Invention] Since the present invention is configured as described above, the following effects can be obtained. The rotation of the nut by the rotation of the operating shaft for the disconnector or the earthing switch rotates the hoisting lever rotatable on the main shaft or the sub shaft, and the rotation is transmitted to the main shaft or the sub shaft via the clutch, and the main shaft or the sub shaft is rotated. Rotation of the spring compresses the spring via the spring lever, and the spring expands rapidly by passing the dead center of the spring lever to rapidly rotate the main shaft or the sub shaft, and the rapid rotation of the main shaft or the sub shaft is performed via the drive lever. A connecting device transmitted to the main lever and connected to the central portion of the main lever rapidly opens and closes, and can perform a required high-speed opening and closing operation, and is simple and inexpensive in configuration.
