The operating direction is designed so that the state changes from the off state to the on state.

作に関連して断路器も切から入状態に移行する。First, to shift from the off state shown in FIG. 3 to the on state shown in FIG. 4, the second operating shaft 11 is rotated counterclockwise by a manual operating device or an electric operating device (not shown). In accordance with this operation, the spring lever 13 stores energy while accumulating the spring member 14 while rotating counterclockwise.
The second long hole link 21 pivotally connected to the link lever 20 moves to the left as viewed in the figure, but since the pin 16 can move inside the long hole 24, the main lever 15 is stationary. Further, the spring lever 13 is rotated, and the dead center 2
When the number exceeds 2, the stored energy is released to rotate vigorously, and the spring lever 13 hits the stopper 23 and stops. On the other hand, the end of the elongated hole 24 comes into contact with the pin 16 and vigorously rotates the main lever 15 in the clockwise direction to reach the entering position. In connection with this operation, the disconnector also shifts from the OFF state to the ON state.

The first operation shaft 10 is rotated counterclockwise by a manual operation device (not shown) or the like. Then, the spring lever 12 accumulates the spring member 14 while rotating counterclockwise,
The first long link 18 pivotally connected to the first link lever 17 moves rightward in the figure, but the main lever 15 is stationary because the pin 16 can move inside the long hole 19. Further, the spring lever 12 is rotated and the dead center 2
When the value exceeds 5, the stored energy is released to vigorously rotate, and the spring lever 12 hits the stopper 26 and stops. On the other hand, the end of the elongated hole 19 comes into contact with the pin 16 and vigorously rotates the main lever 15 counterclockwise to reach the ground contact position. In conjunction with this operation, the disconnector also shifts from off to ground.
【００１７】なお、接地状態から切状態に移行させる操

のなす角度が平行に近くなるように配置してある。In the conventional switch operating mechanism as described above, the angle formed by the slots 19 and 24 between the two first slot links 18 and the second link 21 is reduced. The closer to parallel, the smaller the mutual frictional force between the first long hole link 18 and the second long hole link 21 during the operation of the mechanism, so that a smooth operation can be obtained.
The long hole link 18 and the second long hole link 21 are arranged so that the angle formed by the long holes is almost parallel.

くなるという問題があった。Therefore, the angle between the line connecting the main shaft 9 and the first operation shaft 10 and the line connecting the first operation shaft 10 and the second operation shaft 11 is an obtuse angle (about 130 degrees), The distance between the main shaft 9 and the second operation shaft 11 is significantly longer than the distance between the main shaft 9 and the first operation shaft 10. For this reason, the entire length of the second elongated hole link 21 is increased, and there is a problem that the useless space is large and the volume is large as a whole structure, so that the production cost is increased.

た。Further, the second long hole link 21 is connected to the spring member 1.
Therefore, the first operating shaft 10 and the second operating shaft 11 are respectively provided with a spring lever and a first link lever, or a spring lever and a second link lever.
There was a problem that one lever was required and the number of members increased.

ク調整も困難であるという問題があった。Furthermore, since the operating angle of each lever and link becomes oblique and the number of members that operate vertically or in parallel is small in the entire mechanism, it is difficult to determine the angle of each member from the viewpoint of mechanical design, and it is difficult to assemble. In this case, there is a problem that it is difficult to adjust the stroke of the elongated link or the like.

The number of parts and the volume of the mounting space are reduced, and the size can be reduced. Also, all design and manufacturing problems caused by the large number of levers and links are eliminated.

る。Conventionally, in the case of electric operation, an operation motor is provided for each of the first and second operation shafts, and the spring members are charged each time the motor rotates in the normal and reverse directions. However, a special shaft joint that transmits torque at the time of energy storage and slides at the time of energy release is required, but in the case of the present invention, only an electric motor for energy storage of a spring member is required, and a special shaft installation is unnecessary. And the cost can be reduced.

の可能性も少ない。Whether to switch on / off with the first terminal or on / off with the third terminal can be easily selected by turning the switching lever. Is performed by removing the on / off position holding hooks arranged symmetrically about the line connecting the switching lever and the main shaft, so that both the on / off operation with the first terminal and the on / off operation with the third terminal are performed. The operation is exactly the same, and the configuration is simple, so there is little possibility of failure.

することができる。Further, unlike the conventional operating mechanism in which the spring member is energized to perform the on / off operation, the spring member is previously energized and the hook is removed by the electromagnet to perform the on / off operation. Thus, the operation time from when the switch closing or opening operation signal is received until the ON / OFF operation is completed can be greatly reduced.
