Next, the above-described switch operation of the present invention will be described using FIGS. 5 to 7. The assembly sequence of one embodiment of the device.

As shown in Fig. 5, for example, the first operation lever member 6 and the second operation lever member 7 having the same structure are disposed so that the respective axial cylindrical portions 6A face the respective axial cylindrical portions 7A, and the state is as shown in Fig. 5 The first lever member 7 is reversed with respect to the first lever member 6.

Then, the second operation lever member 7 is moved toward the first operation lever member 6 side, and the convex portion 6g of the first operation lever member 6 and the concave portion 7f of the second operation lever member 7 are fitted in the direction of the arrow in Fig. 5 . At this time, the hole 7a of each of the tubular portion 7A of the second operating lever member 7 and the hole 6a of each of the cylindrical portions 6A of the first operating lever member 6 are aligned with each other in the second operating lever member 7 Each of the barrel portions 7A is fitted to each of the barrel portions 6A of the first operation lever member 6. Then, as shown in Fig. 6, the support shaft 8 is inserted into each of the holes 6a and 7a of the cylindrical portion 6A of the first operation lever member 6 and the cylindrical portion 7A of the second operation lever member 7. Thereby, the first operation lever member 6 and the second operation lever member 7 can be coupled to the support shaft 8 so as to be rotatable around the support shaft 8.

Next, as shown in Fig. 7, the shaft support portion 9 is attached to both ends of the support shaft 8, and after being placed in the casing 2 of the switch 1, the shaft support is supported from the outside of the casing 2 by bolts 10 as shown in Fig. 1. The portion 9 is fixed to the casing 2, and the first operation lever member 6 and the second operation lever member 7 can be installed in the casing 2.

Next, the operation of an embodiment of the above-described operation device in the configuration of the present embodiment will be described.

First, the rod portion 6C of the first operation lever member 6 installed in the casing 2 is connected to the operation lever 4A of the main circuit switch 4 by the pin shaft 11 as shown in Fig. 1 . Further, the rod portions 7C of the second operation lever member 7 are coupled to the operation lever 5A of the ground switch 5 by the pin shafts 12, respectively. Thereby, by the operation of the manipulator, the first operating lever member 6 of each phase and the second operating lever member 7 of each phase can be interlocked, and the main circuit breaker 4 and the grounding of the three phases together are grounded. The switch 5 is switched.

Fig. 8 is a view showing a state in which the main circuit switch 4 and the ground switch 5 of each phase are both in an open state. In this state, as shown in Fig. 4, the angle formed by the rod portion 6C of the first operation lever member 6 and the rod portion 7C of the second operation lever member 7 is approximately 180 degrees. The protruding portion 6i of the rotation preventing member 6E of the first operating lever member 6 is spaced apart from the outer circumference of the cylindrical portion 7A of the second operating lever member 7. Similarly, the protruding portion 7i of the rotation preventing member 7E of the second operating lever member 7 is spaced apart from the outer circumference of the cylindrical portion 6A of the first operating lever member 6.

Fig. 9 shows a case where the main circuit switch 4 of each phase is turned off and the ground switch 5 is turned on. In this state, the angle formed by the rod portion 6C of the first operation lever member 6 and the rod portion 7C of the second operation lever member 7 is 180 degrees or more. Since the rod portion 6C of the first operating lever member 6 and the operating lever 4A must be pushed down, the movable contact in the main circuit switch 4 is brought into contact with the fixed contact. In other words, the angle is determined by the gap between the movable contact and the fixed contact of the main circuit breaker 4, and specifically, it can be realized by the following configuration.

As shown in Fig. 9, when the rod portion 6C of the first operation lever member 6 is rotated in the counterclockwise direction, the front end portion of the projection portion 6ib of the rotation preventing member 6E of the first operation lever member 6 abuts against the second operation lever member. 7 is the outer circumference of the barrel portion 7A. As a result, the rotation preventing member 6E prevents the second operating lever member 7 that drives the grounding switch 5 from rotating in the clockwise direction. In the same manner, the front end of the projection portion 7i of the rotation preventing member 7E of the second operation lever member 7 abuts against the outer circumference of the cylindrical portion 6A of the first operation lever member 6, and the second operation lever member 7 that drives the grounding switch 5 is prevented from being turned toward Rotate clockwise. As a result, the input operation of the ground switch 5 is locked from this state.

Further, even when the main circuit switch 4 of each phase is in the open state and the ground switch 5 is in the OFF state, the tip end of the protrusion 6i of the rotation preventing member 6E of the first operation lever member 6 is abutted against the second operation lever. The outer circumference of the cylindrical portion 7A of the member 7. As a result, the rotation preventing member 6E blocks the rotation of the first operating lever member 6 that drives the main circuit breaker 4. In the same manner, the front end of the projection portion 7i of the rotation preventing member 7E of the second operation lever member 7 abuts against the outer circumference of the cylindrical portion 6A of the first operation lever member 6, and the first operation lever member that drives the main circuit breaker 4 is prevented from being driven. 6 Rotation in the direction of the counterclock. As a result, the input operation of the main circuit breaker 4 is locked from this state.

Here, the relationship between the length of the projection portion 6i of the rotation preventing member 6E and the rotation angle of the first operation lever member 6 will be described in detail using FIG.

Fig. 10 is a side view showing the axial direction of the switch operating device of Fig. 8 in a solid line, and the axial direction side view of the switch operating device of Fig. 9 is indicated by a dotted line. In Fig. 10, 1 is the length of the rod portion 6C, and shows the length between the center of the coupling hole 6B and the hole 6a. θ is a rotation angle of the first operation lever member 6, and shows a rotation angle from the center perpendicular of the hole 6a when the tip end of the projection 6i abuts against the outer circumference of the cylindrical portion 7A of the second operation lever member 7. x is the moving distance of the first operating lever member 6 in the vertical direction, and shows the gap length corresponding to the movable contact and the fixed contact constituting the switch 4.

In the operation of the rotation preventing member shown in Fig. 10, the rotational angle θ and the distance x between the upper and lower directions of the rod member 6 form a rotation preventing member in accordance with the following relational expression.

x=1×tanθ ...(1)

In other words, x is determined based on the gap between the movable contact of the switch 4 and the fixed contact in use, and the rotational angle θ is determined from the length 1 of the rod portion 6C of the first operating lever member 6. Therefore, when the first operation lever member 6 is rotated only by the rotation angle θ, the length of the outer circumference of the shaft portion 7A of the second operation lever member 7 may be formed such that the tip end of the projection portion 6i of the rotation preventing member 6E abuts. Further, in Fig. 10, although only the rotation preventing member 6E of the first operation lever member 6 is displayed, the rotation preventing member 7E for the second operation lever member 7 is also formed in the same relationship.

As described above, the rotation angles of the rod portions 6C and 7C of the respective operation lever members 6 and 7 must be changed in accordance with the gap between the movable contact and the fixed contact of each of the switches 4 and 5, but according to the present embodiment, By adjusting the lengths of the projections 6i, 7i in the respective rotation preventing members 6E, 7E, the angle of rotation of the rod portions 6C, 7C can be easily changed.

According to an embodiment of the above-described switch operating device of the present invention, the first operating lever member 6 of the movable contact of the three-phase main circuit switch 4 is operated together, and the movable contact of the grounding switch 5 is operated together. The base end portions of the second operation lever members 7 are disposed to intersect each other, and the base end portions of the respective operation lever members 6 and 7 are rotatably supported by one common support shaft 8 and are blocked by one of the operation lever members. The other rotation preventing member 6E, 7E for rotating the operating lever member can simplify the locking mechanism of the switch. The result is that it is possible to provide a switch operating device that reduces the number of components.

Further, since the lengths of the tongue portions 6i and 7i in the respective rotation preventing members 6E and 7E are adjusted, the angle of rotation of the rod portions 6C and 7C can be easily changed. Therefore, it is possible to correspond to a switch having various types of contact gaps. This result is a switch operating device that can provide a manufacturing cost and a reduced number of parts.

Further, since the first operation lever member 6 and the second operation lever member 7 have the same structure, they can be manufactured by the same casting model, so that the manufacturing cost and the number of parts can be reduced.

Further, since the first operation lever member 6 and the second operation lever member 7 are integrally molded by the cast material, since the deformation is small, the assembly property is good.
