Abstract

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.

First claim

1 . A gas insulated switching apparatus that includes a switch that is a disconnector, a grounding switch, or a disconnector including a grounding switch in an integrated fashion, and an operating device for the switch, wherein
the operating device comprises:
a drive unit that includes a forwardly and reversely rotatable motor serving as a drive source for driving a movable contactor of the switch, a power source that supplies electric power to the motor, and a first pulley that rotates with rotation of the motor;
a Geneva mechanism that includes a second pulley that rotates with rotation of the first pulley, and a driven wheel that is intermittently driven while the second pulley rotates to drive the movable contactor, the Geneva mechanism being attached to the switch disconnected from the drive unit; and
a flexible rotational force transmission member that is stretched between the first pulley and the second pulley to transmit a rotational force of the motor from the first pulley to the second pulley, wherein
the second pulley includes a projection on one end surface in an axial direction, the driven wheel has a groove with which the projection is engaged, and the groove is V-shaped.

2 . The gas insulated switching apparatus according to claim 1 , wherein the rotational force transmission member is a wire.

3 . (canceled)

4 . (canceled)

5 . The gas insulated switching apparatus according to claim 1 , wherein
the gas insulated switching apparatus includes
a plurality of the switches, and
a plurality of the operating devices, number of which is same as the switches, and
the drive units of the operating devices are housed in a same box.

6 . The gas insulated switching apparatus according to claim 1 , wherein a movement path of the rotational force transmission member between the drive unit and the Geneva mechanism is bent.

7 . A switch that includes a main body of the switch that is a disconnector, a grounding switch, or a disconnector including a grounding switch in an integrated fashion, and an operating device for the switch, wherein the operating device comprises:
a drive unit that includes a forwardly and reversely rotatable motor serving as a
drive source for driving a movable contactor of the switch, a power source that supplies electric power to the motor, and a first pulley that rotates with rotation of the motor;
a Geneva mechanism that includes a second pulley that rotates with rotation of the first pulley, and a driven wheel that is intermittently driven while the second pulley rotates to drive the movable contactor, the Geneva mechanism being attached to the switch disconnected from the drive unit; and
a flexible rotational force transmission member that is stretched between the first pulley and the second pulley to transmit a rotational force of the motor from the first pulley to the second pulley, wherein
the second pulley includes a projection on one end surface in an axial direction, the driven wheel has a groove with which the projection is engaged, and the groove is V-shaped.
