Even if it is attempted, the movable member 6B cannot be moved because the link 8 is taut. Therefore, it is not possible to directly switch from the closed state of the disconnector to the grounded state. Similarly, it is not possible to directly switch from the grounded state to the closed state. Therefore, the interlock between the disconnector section and the grounding switch section can be automatically achieved.

It is possible to obtain an operating device that respectively operates the disconnecting switch part and the grounding switch part of the three-position disconnecting switch. Moreover, since the axial direction of the first and second screw rods, which are the drive shafts, and the axial direction of the output rod 13 are substantially the same, the widthwise dimension of the operating device can be reduced.

持するようにすればよい。In the above-mentioned embodiment, the 3-position disconnector is operated, but it is also possible to operate the 2-position switch which only opens and closes. For example, when operating only the disconnector portion of the above-mentioned three-position disconnector, the screw rod 2B is replaced with the fixing member 20B as shown in FIG. 4 (A), and the end of the link 8 opposite to the screw rod 2A is replaced. The part may be rotatably supported by the fixing member 20B.
Alternatively, when operating only the grounding switch part of the above-mentioned three-position disconnector, as shown in FIG. 4 (B), the screw rod 2A is replaced with the fixing member 20A, and the screw rod 2B of the link 8 is opposite to the screw rod 2A. The end on the side may be rotatably supported by the fixing member 20A.

することができる。In particular, according to the second aspect of the invention, the output rod can be displaced to three positions, so that the three-position disconnector can be operated. In this case, since the input part of the driving force for operating the disconnecting switch part and the input part of the driving force for operating the grounding switch part are independent, the operation of the disconnecting switch and the grounding switch It is not necessary to provide a clutch mechanism for switching between the operation and the operation, and the structure can be simplified.

Therefore, both the disconnecting switch and the grounding switch can be operated electrically or manually, or one and the other of the disconnecting switch and the grounding switch can be operated electrically and manually, respectively. There is an advantage that can have.
