As shown in FIG. 7, in order to charge the closing spring 1 with the vacuum interrupter open, the disk 3 attached to the output shaft of the motor 2 is rotated. Then, while one end is rotatably attached to the eccentric position of the disk 3 via the pin, the pin 4 fixed to the other end engages with the ratchet wheel 5, and a rod provided with a return spring 6 at an intermediate portion. 7 reciprocates vertically. Then, the ratchet wheel 5 is intermittently rotated in the direction of the arrow to accumulate the energizing spring 1, and the rotation of the cam shaft 8 in the opposite direction is prevented by the one-way clutch 9. When the charging is completed, the first roller 11 is supported by the lower end of the insertion hook 14 when the crank 10 occupies a position slightly advanced from the top dead center, and the limit switch 12 moved by the cam 13 detects this. Then, the rotation of the motor 2 is stopped. At this time, the input hook 14 is in contact with the stopper 16 by the action of the return spring 15.

Since the roller 11 is disengaged from the lower end of the insertion hook 14, the cam shaft 8 is vigorously rotated about half a turn in the same direction as that at the time of accumulation by the release of the injection spring 1. As a result, the input cam 18 pushes the second roller 19 downward, and the operation shaft 21 to which the lever 20 is attached rotates counterclockwise, so that the operation shaft 21 is attached to the lever 22 via the press-contact spring 25 and the insulating rod 26. The movable lead rod 23 rises, and the vacuum interrupter 24 is supplied as shown in FIG. Here, 27 is a fixed electrode, 2
8 is a movable electrode. At the same time as the closing operation is performed, the blocking spring 30 is charged via the lever 29, and the closed state is maintained. The holding of the closed state is performed by the third hook attached to the tip of the lever 33 with respect to the trip hook 32 which is rotatably supported by the cam shaft 8 and is urged by the return spring 31 to contact the stopper 36. This is performed by being supported by the lower end of the trip hook 32 when the three rollers 34 move downward and move upward.
