[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] An operating assembly for an outdoor AC high voltage disconnect switch, such as Figure 1-11 As shown, it includes a rod body 1, a connecting component 2 and an adsorption component 3, the adsorption component 3 is arranged on the disconnector, the connecting component 2 is arranged on the rod body 1, and the connecting component 2 is magnetically connected to the adsorption component 3;

[0032] Specifically, Figure 1-11 As shown, the connection assembly 2 includes a connection bracket 21, a connection slider 22 and a first magnet 23. A connection portion 211 is protruded on one side of the connection bracket 21, and the connection portion 211 is used to connect with the adsorption assembly 3. A slide groove 212 is provided on the connection bracket 21, and the connection slider 22 is pulled out and set in the slide groove 212; the first magnet 23 is fixed on the connection slider 22, and the connection slider 22 is connected to a traction rope (not shown). The staff drives the connection slider 22 to move along the slide groove 212 through the traction rope.

[0033] The adsorption assembly 3 includes a fixed bracket 31 and a second magnet 32. A groove 311 is provided on one side of the fixed bracket 31, and the second magnet 32 ​​is provided in the fixed bracket 31. The opposite surfaces of the first magnet 23 and the second magnet 32 ​​have opposite magnetic poles.

[0034] When in use, the adsorption component 3 is pre-fixed on the isolating switch to achieve the transformation of the existing isolating switch. When the isolating switch needs to be operated, the ground staff moves the connecting component 2 to the vicinity of the adsorption component 3 through the rod body 1. However, due to the extremely high operating distance, the rod body 1 will shake. The mutual attraction between the first magnet 23 and the second magnet 32 ​​is used to guide the connecting part 211 into the groove 311 to achieve the connection between the connecting component 2 and the adsorption component 3; and then the isolating switch is driven to open or close through the rod body 1. When the connecting component 2 is separated from the adsorption component 3, the connecting slider 22 is driven to move by the traction rope, so that the first magnet 23 and the second magnet 32 ​​are misaligned, and then the connecting slider 22 is driven away from the adsorption component 3 by the rod body 1 to complete the operation.

[0035] In this embodiment, if Figure 1-11 As shown, in order to ensure that the first magnet 23 is reliably installed in the connecting slider 22, the connecting slider 22 is composed of two plates, and a mounting position that cooperates with the first magnet 23 is recessed on the plate. After the first magnet 23 is embedded in the mounting position, the two plates are spliced ​​and connected by gluing or ultrasonic welding.

[0036] In one embodiment, if Figure 1-11 As shown, the slide groove 212 is a vertically penetrating structure, so that the traction rope can apply force to drive the connecting slider 22 to move downward.

[0037] In one embodiment, if Figure 1-11 As shown, the side wall of the connecting slider 22 is recessed with a mounting groove 221, and a spring 24 is arranged in the mounting groove 221. The spring 24 protrudes from the mounting groove 221, and the spring 24 acts on the side wall of the slide groove 212. Specifically, the spring 24 uses its own elasticity to act on the side wall of the slide groove 212 to increase the damping when the connecting slider 22 moves, so as to prevent the connecting slider 22 from accidentally sliding. At the same time, in accordance with the above-mentioned embodiment, the slide groove 212 is a through-structure from top to bottom, and the connecting slider 22 is inserted from the bottom of the slide groove 212 and protrudes from the upper opening of the slide groove 212. The protruding part of the spring 24 acts on the upper opening of the slide groove 212, which plays a role in temporarily fixing the connecting slider 22.

[0038] In the above embodiment, if Figure 1-11 As shown, the spring leaf 24 includes a continuously arranged riveted portion 241 , a first arc portion 242 and a second arc portion 243 , the riveted portion 241 is riveted in the mounting groove 221 , the first arc portion 242 acts on the slide groove 212 , and the second arc portion 243 acts on the bottom of the mounting groove 221 .

[0039] In one embodiment, if Figure 1-11 As shown, a third magnet 25 is also provided on the connecting slider 22, and the third magnet 25 has the same magnetic pole as the second magnet 32 ​​on the opposite surface. When it is necessary to connect the connecting component 2 with the adsorption component 3, the connecting slider 22 is adjusted so that the first magnet 23 corresponds to the position of the connecting portion 211, and then the attraction between the first magnet 23 and the second magnet 32 ​​is used to insert the connecting portion 211 into the groove 311; when the connecting component 2 is separated from the adsorption component 3, the connecting slider 22 is moved so that the third magnet 25 corresponds to the position of the connecting portion 211, and the force of the opposite repulsion between the third magnet 25 and the second magnet 32 ​​is used to apply an axial thrust to the connecting component 2 away from the adsorption component 3, so as to facilitate the separation of the connecting component 2 from the adsorption component 3. Among them, when separating two magnets that are attracted to each other, pushing one magnet along its radial direction can facilitate the separation of the two magnets.

[0040] In one embodiment, if Figure 1-11 As shown, a connecting shaft 11 is provided at one end of the rod body 1, and a connecting groove 12 matched with the connecting shaft 11 is provided at the other end. The connecting shaft 11 of one rod body 1 and the connecting groove 12 of another rod body 1 are fixed by a latch (not shown). Through the above structure, the rod body 1 can be quickly connected, and the length of the rod body 1 can be adjusted according to actual use requirements. At the same time, the adjacent rod bodies 1 can be prevented from rotating along the axis through the latch connection.

[0041] In the above embodiment, if Figure 1-11 As shown, the connecting bracket 21 is provided with a fixing portion 213 that cooperates with the connecting shaft, and the connecting shaft 11 is fixed to the fixing portion 213 by a latch. Of course, the connection method between the rod body 1 and the connecting bracket 21 is not limited to the above structure, and a rod body 1 can also be fixed to the connecting bracket 21 by welding.

[0042] In one embodiment, if Figure 1-11As shown, the connecting portion 211 is a truncated cone structure, and the inner wall of the groove 311 is an inclined surface. When the isolating switch is driven to open or close, the operating ring 9 of the isolating switch needs to be driven to move downward or upward. By matching the connecting portion 211 with the inner wall of the groove 311 through the inclined surface, the connecting portion 211 and the groove 311 can be reliably connected through the decomposition of force. Among them, the opening of the groove 311 is larger than the connecting portion 211, so that the connecting portion 211 can be inserted into the groove 311. In addition, because the size of the groove 311 is larger than the size of the connecting portion 211, the connecting portion 211 and the groove 311 are floatingly connected; and when the first magnet 23 and the second magnet 32 ​​are misaligned, the mutual attraction will be greatly reduced, and it is impossible to ensure that the connecting portion 211 and the groove 311 are connected to each other; therefore, by setting the connecting portion 211 as a truncated cone structure and setting the inner wall of the groove 311 as an inclined surface, it is ensured that even if the first magnet 23 and the second magnet 32 ​​are misaligned, the connecting portion 211 and the groove 311 are still connected together.

[0043] In one embodiment, if Figure 1-11 As shown, the fixed bracket 31 includes a first side plate 312 and a second side plate 313, the groove 311 is arranged on the first side plate 312, the second side plate 313 is arranged with a mounting cavity 314, the side wall of the mounting cavity 314 is radially protruding inwardly with a connecting rib 315 connected to the second magnet 32, and the first side plate 312 and the second side plate 313 are connected and fixed to the operating ring 9 of the isolating switch.

[0044] In the above embodiment, if Figure 1-11 As shown, ventilation holes 316 are provided on the first side plate 312 and the second side plate 313. Since the isolating switch generates heat when working, in order to ensure that the magnet can work effectively, the magnet is ventilated by providing the connecting ribs 315 and the ventilation holes 316 to increase the service life of the magnet.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. If the present invention is modified or replaced by equivalents without departing from the spirit and scope of the present invention, they should all be included in the protection scope of the claims of the present invention.
