停止し、第２図の状態となる。Further, the driven body 21 is connected to the switch operating section 2 as shown in FIG.
Position detection switches 27 to 30 each having a limit switch as an example for detecting the position of the switch actuation part 26 are arranged at four locations in the moving direction of the driven body 21 of the base 8 corresponding to the switch actuation part 26. It is set up. The position detection switches 2730 at both ends detect the position at which the switch actuation section 26 is moved in the opposite direction, and the position detection switches 28 and 29 detect the position at which the switch operation section 26 that has moved in the opposite direction is stopped. That is, when the motor 15 rotates in the direction R in the state shown in FIG. 2, the screw shaft 16 rotates and the driven body 21 moves in the direction 15 rotates in the opposite direction to the direction S, the screw shaft 16 rotates in the opposite direction, the driven body 21 moves in the opposite direction Y, and the switch actuating part 2
6 presses the position detection switch 28 and stops. Furthermore, when the motor 15 is rotated in the direction S from this stop position, the driven body 21 moves in the direction Y and presses the position detection switch 30.
As a result, the motor 15 rotates in the opposite direction in the direction R, the screw shaft 16 rotates in the direction R, the driven body 21 moves in the direction The state shown in Figure 2 will be obtained.

。In addition, the switch actuator 26 presses the position detection switch 27 from the position detection switch 29 through the position detection switch 28 in the ON operation, and then reverses and presses the position detection switch 2nd.
The contact point of the position detection switch 28 is configured not to operate during the process of moving to. This can be achieved, for example, by a circuit configuration, by using a switch that turns on when pressed twice, or by providing a directional pressing part that applies a pressing force only when moving the switch actuating part 26 in one direction. . The same applies to the position detection switch 29 which is pressed twice when the switch operating section 26 is turned off.

The plate-shaped portion is connected to the driven body 21 at 7 and has a protrusion 33 for guiding the operating member at the center of the upper surface 22 of the plate-like portion on which the operating member 2 is placed. Further, a recess 23 is formed at one end in a direction perpendicular to the moving direction, which is the operating direction of the handle 4, and the drive unit 1 is formed in the recess 23.
A power supply switch 25 is provided to control the power supply 24 of the third embodiment, and safety is ensured during maintenance and inspection by operating the @'II switch 25.

している。The operating member 2 has an operating section 20 for operating the handle 4 and is connected to the movable body 17 of the drive section 13 . The operating member 2 of the embodiment is formed of a rectangular plate placed on the upper surface 22 of the movable body 17, and has a hole 34 into which a protrusion 33 is fitted so as to be slidable in a direction perpendicular to the operating direction of the handle 4. 2
0 is formed at one end. By using a notch as an embodiment, this operating section 20 enables movement in a direction perpendicular to the operating direction of the operating member 2, and also enables the operating section 20 to be engaged with and detached from the handle 4. Since it is exposed, it also serves as a viewing part for checking the operating state of the handle 4. In this way, the operability of the circuit breaker 3 is maintained by making the operating member 2 movable in a detachable manner from the handle 4, and making it possible to directly manually operate the handle 4 of the circuit breaker 3.

、誤操作を防止している。In addition, by using the operation unit 20 as a visual part for visually checking the operating state of the circuit breaker 3 in the operating member 2, the operating state of the circuit breaker 3 can be easily determined visually. Furthermore, the operating section 20 has a cutout width that allows the handle 4 to be freely moved from the on position to the trip display position without moving the operating member 2, thereby facilitating trip display. I make it visible. Furthermore, by moving the operating member 2 and disengaging it from the handle 4, the operating member 2 pushes the power switch 25 to disconnect 1ii524 of the drive unit 13, thereby eliminating the possibility that the operating member 2 will operate during manual operation. This prevents misoperation.

FIG. 1 (Al) The operating portion 20 of the operating member 2 is released from the engagement with the handle 4 by manually pushing the operating portion 20 of the operating member 2 toward the main body 1 side and moving the hole 34 of the operating member 2 relative to the protrusion 33. In this state, the handle 4 can be directly operated manually, and the power switch 25 is turned off by the operating member 2, so the drive unit 13 is not operated by a remote signal.

を有するのでハンドル４はオフ方向には押されない。FIG. 1 (bl) shows a state in which the operating member 2 is pulled out in the direction of the arrow and the operating portion 20 of the operating member 2 is engaged with the handle 4, the handle 4 is in the on position, and the space inside the operating portion 20 is shown. 4 (al).At this time, since the operating member 2 is away from the power switch 25, power is supplied to the control circuit shown in FIG. 5, and the drive unit 13 becomes operable. When the on switch 45 is closed, a remote signal for turning on the handle 4 is input to the control circuit of the drive unit 13, and the rotation of the motor 15 in the direction R causes the screw shaft 16 to be turned on.
The movement of the protrusion 33 of the moving body 17 in the direction The state shown in FIG. 1 (101 and FIG. 4) is reached. Furthermore, since the switch actuator 26 is in the state where the position detection switch 27 is pressed, the motor 15 rotates in the reverse direction,
As the moving body 17 moves in the opposite direction, the operating member 2
similarly moves in the opposite direction, and stops when the switch operating portion 26 hits the position detection switch 28, resulting in a telO-shaped snoring in FIG. 4 (arrow in FIG. 1 101).
The distance from bl to fc in the same figure is set equal to the range of movement from the on position of the handle 4 to the trip display position, and the operating section 20 of the operating member 2 is set to move within the range from the on position of the handle 4 to the trip display position. Since the handle 4 has a width corresponding to the distance, the handle 4 is not pushed in the off direction.

When an overcurrent or the like flows in this electrical circuit, the circuit breaker 3 displays a trip indication, and therefore the handle 4 moves from the on position to the trip indication position.
The operating member 2 does not move, but moves only as shown by the arrow in FIG. 1+di or the imaginary line in FIG. 4 (C1).Resetting after tripping is performed by moving the handle 4 to the OFF side.
