[0048] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description.

Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0051] Please also read Figures 1 to 3 The high-voltage disconnector provided by the utility model is now described. The high-voltage disconnector comprises a base 10, an active insulator 20, a driven insulator 30, a first connecting rod 40 and a transmission mechanism. The base 10 is suitable for being installed on the cross arm of a pole; the active insulator 20 is connected to the base 10 and rotates with the base 10; a first contact is provided on the active insulator 20; the driven insulator 30 is arranged at intervals on one side of the active insulator 20, connected to the base 10, and rotates with the base 10; a second contact is provided on the driven insulator 30; the two ends of the first connecting rod 40 are respectively rotated with the active insulator 20 and the driven insulator 30, so that when the active insulator 20 and the driven insulator 30 rotate, they rotate synchronously in opposite directions, so that the first contact and the second contact are in contact or disconnected; the transmission mechanism is arranged on one side of the base 10, the power output end of the transmission mechanism is connected to the active insulator 20, and the power input end is suitable for being connected to the driving mechanism; and the power input end is spaced a preset distance from the base 10.

[0052] It should be noted that the preset distance is a distance set according to construction specifications. After ensuring that the power output end of the transmission mechanism is spaced a preset distance from the base 10, the portion of the driving mechanism connected to the power output end of the transmission mechanism that is connected to the cable can be placed directly above the main cable trench. In this way, there is no need to dig a branch cable trench leading to the driving mechanism.

[0053] The beneficial effect of the high-voltage disconnector provided by the utility model is that: compared with the prior art, the high-voltage disconnector provided by the utility model transmits the power of the driving mechanism through the transmission mechanism to drive the active insulator 20 and the driven insulator 30 to rotate, and the power input end of the transmission mechanism is spaced apart from the base 10 by a preset distance, so that the driving mechanism and the disconnector are installed in a staggered manner, so that the part of the driving mechanism connected to the cable is also spaced apart from the base 10 by a certain distance on the ground projection and coincides with the main cable trench, so that the cables in the main cable trench can be directly connected to the driving mechanism without the need to dig a branch cable trench leading to the driving mechanism, which greatly reduces the workload and improves the construction efficiency.

[0054] like Figure 1 and Figure 2 As shown, in a specific implementation manner of the high-voltage disconnector provided by an embodiment of the utility model, the transmission mechanism includes a mounting plate 51, a receiving shaft 52, a crank 54 and a second connecting rod 55. The mounting plate 51 is arranged on one side of the base 10 and is connected to the base 10; the receiving shaft 52 is rotatably connected to the mounting plate 51 and has the freedom to rotate around its own axis. The axis of the receiving shaft 52 is spaced a preset distance from the base 10 and is used to be coaxially connected to the transmission shaft of the driving mechanism; the crank 54 is connected to the receiving shaft 52, one end of which is connected to the receiving shaft 52, and the other end is provided with a first rotating shaft; one end of the second connecting rod 55 is rotatably connected to the first rotating shaft on the crank 54, and the other end is rotatably connected to the active insulator 20.

[0055] When the receiving shaft 52 rotates by a preset angle, the active insulator 20 is driven to rotate by 90°.

[0056] It should be noted that, when working, the transmission shaft of the driving mechanism is connected to the receiving shaft 52, driving the receiving shaft 52 to rotate, and the receiving shaft 52 drives the crank 54 to rotate a certain angle. During this process, the active insulator 20 is driven to rotate 90° through the second connecting rod 55, and the active insulator 20 drives the driven insulator 30 to rotate 90° in the opposite direction synchronously through the first connecting rod 40, so that the first contact and the second contact are in contact or separated.

[0057] Specifically, Figure 1 and Figure 2 As shown, in a specific implementation of the high-voltage disconnector provided in an embodiment of the utility model, the preset angle is 180° to facilitate the regulation of the action of the driving mechanism.

[0058] like Figure 1 and Figure 2As shown, in a specific implementation of the high-voltage disconnector provided in an embodiment of the utility model, two long holes are provided on the crank 54 along the length direction, and the extension direction of the long hole is parallel to the length direction of the crank 54. Two adjusting bolts 53 are provided on the top of the receiving shaft 52. The two adjusting bolts 53 pass through the two long holes respectively and are connected to the receiving shaft 52 to fix the crank 54 on the receiving shaft 52. The adjusting bolts 53 have the freedom to move in the long hole along the long extension direction.

[0059] It should be noted that by loosening the adjusting bolt 53, moving the crank 54 along the length direction of the crank 54, and then tightening the adjusting bolt 53, the distance between the connection position of the crank 54 and the second connecting rod 55 and the receiving shaft 52 can be adjusted, thereby adjusting the relationship between the rotation angle of the receiving shaft 52 and the rotation angle of the active insulator 20.

[0060] like Figure 1 and Figure 3 As shown, in a specific implementation manner of the high-voltage disconnector provided in an embodiment of the utility model, the first connecting rod 40 and the second connecting rod 55 each include two screws 41 and a threaded sleeve 42, the two screws 41 are coaxial and spaced apart, and nuts 43 are provided on the screws 41, and the threads on the two screws 41 have opposite rotation directions; the threaded sleeve 42 is provided between the nuts 43 on the two screws 41 and is threadably matched with the two screws 41.

[0061] It should be noted that by rotating the two nuts 43 to keep them away from the threaded sleeve 42, and then rotating the threaded sleeve 42 forward or reversely, the total length of the first connecting rod 40 or the second connecting rod 55 can be adjusted. Then, by rotating the two nuts 43 in the reverse direction to make them press against both ends of the threaded sleeve 42, the threaded sleeve 42 can be locked to prevent the threaded sleeve 42 from rotating, thereby locking the total length of the first connecting rod 40 or the second connecting rod 55.

[0062] like Figure 1 and Figure 3 As shown, in a specific implementation of the high-voltage disconnector provided in an embodiment of the utility model, the threaded sleeve 42 is a polygonal columnar structure.

[0063] like Figure 1 and Figure 2 As shown, in a specific implementation of the high-voltage disconnector provided in an embodiment of the utility model, the first contact includes a first mounting seat 21 and two conductive clamping plates 22, the first mounting seat 21 is connected to the active insulator 20; the two conductive clamping plates 22 are parallel and spaced apart, one end of the two conductive clamping plates 22 is connected to the first mounting seat 21, and the other ends of the two conductive clamping plates 22 are opened outward in a V shape.

[0064] The second contact includes a second mounting seat 31 and a conductive plate 32 . The second mounting seat 31 is connected to the driven insulator 30 . One end of the conductive plate 32 is connected to the second mounting seat 31 , and the other end is a conductive column 33 . The conductive column 33 is suitable for being placed between the two conductive clamping plates 22 and in contact with the two conductive clamping plates 22 .

[0065] The first mounting seat 21 is electrically connected to the conductive clamping plate 22 , and the second mounting seat 31 is electrically connected to the conductive plate 32 .

[0066] It should be noted that the other ends of the two conductive clamping plates 22 are opened outward in a V-shape, so that the conductive pillar 33 on the second contact can enter between the two conductive clamping plates 22 .

[0067] like Figure 1 and Figure 2 As shown, in a specific implementation manner of the high-voltage disconnector provided in an embodiment of the utility model, the first contact also includes a fixed block 23 and two V-shaped plates 24, the fixed block 23 is arranged on two conductive clamping plate 22 brackets and is connected to the conductive clamping plate 22; the two V-shaped plates 24 are respectively arranged on the outer sides of the two conductive clamping plates 22, and one end is fixed to the position of the fixed block 23 on the conductive clamping plate 22 by fastening bolts, and the fastening bolts pass through the V-shaped plate 24 and the conductive clamping plate 22 and are connected to the fixed block 23; the other end of the V-shaped plate 24 abuts against the conductive clamping plate 22 on the side of the fixed block 23 facing the second contact, and squeezes the conductive clamping plate 22 inward.

[0068] It should be noted that the two V-shaped plates 24 squeeze the two conductive clamps 22 to bend inward, so that the conductive pillars 33 on the conductive plate 32 enter between the two conductive clamps 22. There is a certain pressure between the conductive clamps 22 and the conductive pillars 33 to avoid virtual connection and ensure a good conductive effect.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
