[0004] In actual use, air switches are installed in various locations. For example, in a 35-kilowatt substation, the voltage circuit generally has wiring from the small busbar to the terminal block, from the terminal block to the voltage air switch, and from the voltage air switch directly to the protection device. When the voltage is increased, the wires are always easy to fall off. When the distance from the air switch to the terminal block is very narrow, the wiring work of the staff is inconvenient.

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0036] Example 1

[0037] Reference Figures 1 to 10 , which is the first embodiment of the present invention, provides a voltage air switch adding tool that is easy to quickly install and remove, including:

[0038] The main body 100 includes an air switch 101 and a wiring component 102 adapted to be installed inside the air switch 101;

[0039] The auxiliary mechanism 200 includes a cable tie 201 wrapped around the outside of the air switch 101 , a connecting component 202 adapted to be installed inside the cable tie 201 , and a contact component 203 adapted to be installed inside the connecting component 202 .

[0040] Specifically, the wiring component 102 includes a threaded rod 102a threadedly connected to the inside of the air switch 101, and a wire pressing block 102b rotatably connected to the outside of the threaded rod 102a.

[0041] Furthermore, the terminal component 102 further includes a bolt head 102c fixedly connected to the outside of the threaded rod 102a, and a cross slot 102d formed inside the bolt head 102c.

[0042] Furthermore, the connecting component 202 includes a rotating cylinder 202a rotatably connected to the inside of the cable tie 201, and a limiting block 202b fixedly connected to the outside of the rotating cylinder 202a.

[0043] Preferably, the connecting component 202 further includes a cylinder 202c fixedly connected to the outside of the rotating cylinder 202a, and a hexagonal groove 202d provided inside the cylinder 202c.

[0044] It should be noted that the contact member 203 includes a square block 203a slidably connected to the inside of the rotating cylinder 202a, and a spring 203b disposed outside the square block 203a;

[0045] One end of the spring 203b is fixedly connected to the outside of the square block 203a, and the other end of the spring 203b is fixedly connected to the inside of the cylinder 202c.

[0046] In addition, the contact component 203 further includes a cylinder 203c fixedly connected to the bottom end of the square block 203a, and an auxiliary component 203d adapted to be installed on the outside of the cylinder 203c.

[0047] Furthermore, the auxiliary component 203d includes a contact plate 203d-1 fixedly connected to the outside of the cylinder 203c, and a cross protrusion 203d-2 fixedly connected to the outside of the contact plate 203d-1.

[0048] Furthermore, the auxiliary component 203d further includes a straight surface 203d-3 disposed on one side of the cross protrusion 203d-2, and a sloped surface 203d-4 disposed on the other side of the cross protrusion 203d-2.

[0049] The cable tie 201 is made of flexible material, and the connecting component 202 and the contact component 203 are made of conductive metal material.

[0050] When in use, the staff wraps the cable tie 201 around the outside of the air switch 101 and connects the ends. When installing the cable tie 201, it should be noted that the cross protrusion 203d-2 is aligned with the bolt head 102c, so as to ensure that the cross protrusion 203d-2 and the bolt head 102c are in contact with each other when the cable tie 201 is installed.

[0051] At this time, since the connecting component 202 and the contact component 203 are both made of conductive metal materials, the staff can directly install the wire on the outside of the cylinder 202c and connect the wire to the air switch 101.

[0052] This wiring method does not require inserting wires from the top or bottom of the air switch 101, but directly connects the wires outside the air switch 101, so wiring is very convenient in a narrow space.

[0053] Example 2

[0054] Reference Figure 1 to Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that a working process of an auxiliary mechanism 200 is provided.

[0055] After the cable tie 201 is installed, although the cross protrusion 203d-2 contacts the bolt head 102c, the cross protrusion 203d-2 may not be inserted into the cross groove 102d. If it fails to be inserted, the contact area between the cross protrusion 203d-2 and the bolt head 102c is small, the connection is unstable, and faults are likely to occur in the circuit.

[0056] To solve the above problem, the staff can use a hexagonal wrench to twist the cylinder 202c through the hexagonal groove 202d, so that the cylinder 202c drives the rotating cylinder 202a to rotate, and the rotating cylinder 202a then drives the cross protrusion 203d-2 to rotate through the square block 203a and the cylinder 203c.

[0057] When the cross protrusion 203d-2 rotates to align with the cross groove 102d, the cross protrusion 203d-2 is pushed by the spring 203b to be inserted into the cross groove 102d, thereby ensuring a stable connection.

[0058] Example 3

[0059] Reference Figures 1 to 10 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that other working processes of the auxiliary mechanism 200 are provided.

[0060] During the process of rotating the cylinder 202c to make the cross protrusion 203d-2 fit into the cross groove 102d, it is difficult for the staff to judge whether the cross protrusion 203d-2 fits into the cross groove 102d due to the obstruction of vision.

[0061] At this time, when the staff rotates the cylinder 202c, its rotation direction is Figure 7 ~Attached Fig.10 When the threaded rod 102a is rotated in this direction, the threaded rod 102a moves toward the adjacent Figure 7 ~Attached Fig.10 Move in the direction indicated by the arrow.

[0062] When the bolt head 102c is in the Fig. 9 When the bolt head 102c is in the position shown in FIG. 1 , the bolt head 102c cannot continue to descend, that is, the bolt head 102c cannot continue to move along the attached Figure 7 ~Attached Fig.10 When rotating in the direction shown, the staff continues to twist the cylinder 202c. Since the bolt head 102c cannot continue to rotate, the inclined surface 203d-4 on the outside of the cross protrusion 203d-2 will be squeezed against the side of the cross groove 102d. Under the action of the squeezing force, the cross protrusion 203d-2 will move up.

[0063] When the cross protrusion 203d-2 moves up to the adjacent Fig.10When the cross protrusion 203d-2 is in the position shown, the cross protrusion 203d-2 is completely disengaged from the cross groove 102d. When the cross protrusion 203d-2 continues to rotate until it is aligned with the cross groove 102d, the cross protrusion 203d-2 will be stuck into the cross groove 102d under the elastic force of the spring 203b. Therefore, when the staff continues to rotate the cylinder 202c, the cross protrusion will repeatedly go in and out of the cross groove 102d. Every time the cross protrusion 203d-2 is stuck into the cross groove 102d under the elastic force of the spring 203b, the contact plate 203d-1 will collide with the bolt head 102c once, thereby making a metal collision sound. When the staff hears the metal collision sound when rotating the cylinder 202c, they can know that the cross protrusion 203d-2 has been stuck into the cross groove 102d and can stop rotating.

[0064] It is worth noting that before the cable tie 201 is installed, the position of the bolt head 102c is uncertain, and not all bolt heads 102c are in the adjacent Fig. 9 As shown in the position, therefore, when the bolt head 102c is located near Figure 7 When the air switch 101 is in the position shown, two situations may occur. In the first situation, the friction between the threaded rod 102a and the air switch 101 is relatively large. In the second situation, the friction between the threaded rod 102a and the air switch 101 is relatively small.

[0065] When the first situation occurs, when the staff rotates the cylinder 202c, the friction between the threaded rod 102a and the air switch 101 is large, so the threaded rod 102a is difficult to rotate, and the outer inclined surface 203d-4 of the cross protrusion 203d-2 will be squeezed with the side of the cross groove 102d. Under the action of the squeezing force, the cross protrusion 203d-2 will move up to the adjacent Figure 8 As shown in the position, after the cross protrusion 203d-2 is aligned with the cross groove 102d, the contact plate 203d-1 will collide with the bolt head 102c, and when the staff hears a metal collision sound, the rotation can be stopped.

[0066] When the second situation occurs, when the staff rotates the cylinder 202c, the threaded rod 102a is easily rotated due to the small friction between the threaded rod 102a and the air switch 101. When the cross protrusion 203d-2 rotates, when the cross protrusion 203d-2 rotates to align with the cross groove 102d, the cross protrusion 203d-2 will be stuck in the cross groove 102d. Continuing to rotate the cross protrusion 203d-2 will cause the cross protrusion 203d-2 to drive the threaded rod 102a to rotate synchronously. Rotate until the threaded rod 102a rotates to the point where it can no longer be driven by the cross protrusion 203d-2, and then continue to rotate the cylinder 202c, which will cause the outer inclined surface 203d-4 of the cross protrusion 203d-2 and the side of the cross groove 102d to squeeze each other. Under the action of the squeezing force, the cross protrusion 203d-2 will move up, so that after the cross protrusion 203d-2 is aligned with the cross groove 102d, the contact plate 203d-1 will collide with the bolt head 102c, and when the staff hears a metal collision sound, they can stop rotating.

[0067] Based on the above situations, the staff only needs to rotate the cylinder 202c to simply determine whether the cross protrusion 203d-2 is stuck in the cross groove 102d, which is simple and convenient to operate.

[0068] In summary, through the cooperation of various components, it is possible to achieve the connection method from the upper and lower ends of the air switch 101 to the outside of the air switch 101 by connecting a metal component to the outside of the bolt head 102c. In a narrow environment, this wiring method is simple and convenient, and by twisting the cylinder 202c, the contact component 203 and the wiring component 102 can be more tightly connected, and whether the connection is tight can be easily judged based on the metal collision. The operation process is simple, which reduces the burden on the staff.
