置は、クラッチレバ−の切替えによって。This invention was made in order to prevent such dangerous operation. The purpose of this invention is to obtain an operating device incorporating a so-called danger prevention mechanism that prevents the required operation from being performed unless the user performs the necessary operations. The 8-point disconnector operation device for insulated switchgear separates the operating points for human, cut operation, and cut-to-ground operation, and is also useful when moving from an important operation to a cut-to-ground operation, or from a cut-to-ground operation to an entry operation. In some cases, the above operation cannot be performed unless the clutch lever is first switched.0 [Function] The eight-point disconnector operating device for a gas-insulated switchgear according to the present invention is configured to operate by switching the clutch lever.

As shown in FIG. 8, the operation of the on/off operation actuator 10 is transmitted to the operating mechanism lever 5 via the lever 11 and linkage, causing it to rotate by this amount. This rotational movement is transmitted to the shaft-directly connected lever 4 via the clutch lever 6 connected with the switching pin 7.9, rotates the operating shaft 3, and performs the important operation of the eight-point street device 2. Next, for the cutting/grounding operation, as shown in FIGS. 4 and 5, the clutch lever 6 is pulled out and the switching pin 8 is inserted into the pin hole 4a of the shaft-directly connected lever 4, thereby connecting the operating mechanism lever 5. The shaft-directly connected lever 4 is separated. At this point, move the clutch lever 6 to the fifth position.
When rotated as shown in the figure, the disconnection/grounding operation of the 8-point disconnector 2 is interrupted. In the above embodiment, the clutch lever 6
A switching pin 7.8.9 is provided protrudingly on the lever 5 for the operation mechanism.
2 and 4 are shown in which the pin holes 5a and 4a are provided in the shaft-directly connected lever 4, but on the contrary, a switching pin is provided protruding from the operating mechanism lever 5 and the shaft-directly connected lever 4, and the clutch lever 6 is
[Effects of the Invention] As described above, according to the present invention, the operating points for the cutting operation and the cutting operation are separated, and the cutting operation for the above operations is separated. Since the structure requires a switching operation using a clutch lever, erroneous operation can be completely prevented.
