Embodiment 1
[0023] figure 1 is a top view of the electromagnetic operating device of the present invention, figure 2 is the front view including the electromagnetic manipulator and controller, Figure 3A , Figure 3B is a side view including the main shaft and the three-phase connecting shaft.
[0024] Such as figure 1 As shown, the vacuum valves 1 of each phase are respectively connected to the electromagnetic operator 4 through the main shaft 2 . The main shafts 2 freely start to move in each phase, and are connected by a three-phase connection shaft 3 as described later, so that synchronization among the main shafts 2 is obtained.
[0025] Such as figure 2 As shown, the electromagnetic operating device is accommodated in a box-shaped multi-segment frame body 8, controllers such as a control board 81 and a capacitor 82 are accommodated in the upper segment 8-1, and the electromagnetic operator 4 is accommodated in the middle segment 8-2. . As shown in the figure, the upper sect...
Embodiment 2
[0039] A second embodiment of the present invention will be described below. Figure 5 , Image 6 It is an embodiment in which the three-phase connection shaft 3 is arranged on the upper part of the electromagnetic operator 4 .
[0040] The three-phase connection shaft 3 is arranged on the upper side of the electromagnetic operator 4 , and the main shaft 2 is arranged on the lower side of the electromagnetic operator 4 . The connection of the two axes is performed by the rod 44 of the electromagnetic operator 4 . That is, since the rod 44 is connected to the vane 45 of the main shaft 2 via the fulcrum 46 , the movement of the rod 44 can be transmitted to the vane 47 of the upper three-phase connection shaft 3 . Thus, the three-phase connection shaft 3 can achieve synchronization among the respective main shafts 2 .
Embodiment 3
[0042] A third embodiment of the present invention will be described below. Figure 7 This is an example in which the three-phase connection shaft 3 is arranged on the vacuum valve 1 side. The difference from the first embodiment is that the three-phase connecting shaft 3 is arranged on the lower part of the main shaft 2 on the side of the vacuum valve 1 . The connecting portion 7 is provided between the vane 45' on the vacuum valve 1 side of the main shaft 2 and the vane 47 of the three-phase connecting shaft 3. The linked action is the same as in the first embodiment.
[0043]The three embodiments described above should be appropriately selected according to the configuration of the electromagnetic operation device. For the first and third embodiments, the main shaft and the three-phase connection shaft are arranged in the same frame area, so it is easy to assemble or Adjustment. On the other hand, the second embodiment has a structure that does not require a connecting p...
