[0033] In order to solve the problem of a large floor space occupied by a three-pole isolating switch in the prior art, the present application provides a linkage isolating switch.

[0034] Embodiment 1

[0035] like Figures 1 to 5 As shown, the linkage disconnector includes three isolation bodies 20, a power output device 30, a main transmission structure 40 and an auxiliary transmission assembly 50. Among them, the three isolation bodies 20 are arranged at intervals along the height direction, and each isolation body 20 includes a conductive structure group 21, a contact 22 and a contact finger 23. The conductive structure group 21 includes two conductive structures that rotate synchronously and in opposite directions. The contact 22 is arranged on one conductive structure, and the contact finger 23 is arranged on the other conductive structure. The power output device 30 is drivingly connected to the main transmission structure 40 to drive the main transmission structure 40 to rotate. The auxiliary transmission assembly 50 is arranged on the main transmission structure 40, and the main transmission structure 40 drives the two conductive structures of the conductive structure group 21 to rotate through the auxiliary transmission assembly 50, so that each isolation body 20 is in a closed state in which the two conductive structures rotate to insert the contact 22 into the contact finger 23 and an open state in which the two conductive structures rotate to separate the contact 22 and the contact finger 23.

[0036] By applying the technical solution of this embodiment, the three isolation bodies 20 are arranged at intervals along the height direction, that is, the three isolation bodies 20 are respectively located at different heights, thereby reducing the overall footprint of the linkage disconnector, solving the problem of the large footprint of the three-pole disconnector in the prior art, and improving the versatility of the linkage disconnector, so that its use place is not restricted. At the same time, when the three isolation bodies 20 are required to close or open the switch, the power output device 30 drives the main transmission structure 40 to rotate, so as to drive the auxiliary transmission assembly 50 to drive the two conductive structures of the conductive structure group 21 to rotate through the main transmission structure 40, so that the contact 22 is inserted into the contact finger 23 for closing or withdrawn from the contact finger 23 for opening, so as to ensure that the linkage disconnector can operate normally.

[0037] In this embodiment, each isolation body 20 includes a conductive structure group 21 .

[0038] like Figure 1As shown, the linkage disconnector further includes a bracket 10, and three isolation bodies 20 are arranged on the bracket 10 at intervals along the height direction of the bracket 10. The main transmission structure 40 is rod-shaped, and there are three auxiliary transmission assemblies 50. The three auxiliary transmission assemblies 50 are arranged at intervals along the extension direction of the main transmission structure 40, and the three auxiliary transmission assemblies 50 are arranged one by one with the three isolation bodies 20; wherein, the extension direction of the main transmission structure 40 is consistent with the height direction of the bracket 10. In this way, each auxiliary transmission assembly 50 drives the conductive structure group 21 of the corresponding isolation body 20 to move, on the one hand, it realizes the synchronous opening and closing movement of the three conductive structure groups 21 driven by one main transmission structure 40, reduces the number of transmission structures, and reduces the difficulty of disassembly and assembly of the linkage disconnector; on the other hand, it improves the movement stability and reliability of the three conductive structure groups 21, thereby improving the operation reliability of the linkage disconnector. At the same time, the above-mentioned setting makes the structure of the main transmission structure 40 simpler, easy to process and realize, and reduces the processing cost and processing difficulty of the main transmission structure 40.

[0039] In this embodiment, three auxiliary transmission assemblies 50 are arranged at intervals along the height direction of the bracket 10 .

[0040] like Figures 3 to 5 As shown, the two conductive structures include a first conductive structure 211 and a second conductive structure 212, and the auxiliary transmission assembly 50 includes a first crank arm 51, a first transmission structure 52 and a second transmission structure 53. The first end of the first crank arm 51 is connected to the main transmission structure 40, one side of the first transmission structure 52 is pivotally connected to the first conductive structure 211, and the other side of the first transmission structure 52 is pivotally connected to the second end of the first crank arm 51. One side of the second transmission structure 53 is pivotally connected to the first conductive structure 211, and the other side of the second transmission structure 53 is pivotally connected to the second conductive structure 212. In the horizontal direction, the first conductive structure 211 is located between the second conductive structure 212 and the main transmission structure 40. In this way, the above arrangement ensures that the auxiliary transmission assembly 50 can simultaneously drive the first conductive structure 211 and the second conductive structure 212 to rotate synchronously and in opposite directions, so as to realize the opening or closing of the isolation body 20. At the same time, the above arrangement makes the structure of the auxiliary transmission assembly 50 simpler, easier to process and realize, and reduces the processing cost and difficulty of the auxiliary transmission assembly 50.

[0041] Specifically, the first transmission structure 52 drives the first conductive structure 211 to rotate, and the second transmission structure 53 drives the second conductive structure 212 to rotate. During the rotation of the main transmission structure 40, the first crank 51 rotates synchronously with the main transmission structure 40 to drive the first conductive structure 211 to rotate through the first transmission structure 52. At the same time, the first conductive structure 211 drives the second conductive structure 212 to rotate through the second transmission structure 53 to achieve the opening or closing of the isolation body 20.

[0042] like Figure 1 and Figure 3 As shown, each isolation body 20 also includes a base 24, and the conductive structure group 21 is rotatably arranged on the base 24; the bracket 10 includes three cantilever beams 11. Among them, the three cantilever beams 11 are arranged at intervals along the height direction, and the three cantilever beams 11 are arranged one-to-one with the three isolation bodies 20, and the base 24 of each isolation body 20 is arranged on the cantilever beam 11 corresponding thereto. In this way, the above arrangement ensures that the three isolation bodies 20 are arranged at intervals along the height direction of the bracket 10 to reduce the overall floor space; on the other hand, the structure of the bracket 10 is simpler, easy to process and realize, and the processing cost and difficulty of the bracket 10 are reduced.

[0043] In this embodiment, the cantilever beam 11 extends in the horizontal direction.

[0044] like Figure 3 As shown, the extension direction of the first crank arm 51 is perpendicular to the extension direction of the main transmission structure 40, and the first transmission structure 52 includes a first connecting shaft 521 and a first transmission rod 522. The first connecting shaft 521 is arranged on the second end of the first crank arm 51, the first end of the first transmission rod 522 is connected to the first connecting shaft 521 and is spaced apart from the first crank arm 51 along the extension direction of the first connecting shaft 521, and the second end of the first transmission rod 522 is pivotally connected to the first conductive structure 211. Among them, the extension direction of the first connecting shaft 521 is perpendicular to the extension direction of the first crank arm 51. Optionally, the first angle is 90°. Optionally, the second angle is 90°. In this way, the two ends of the first transmission rod 522 are connected to the first conductive structure 211 and the first connecting shaft 521 respectively, the first connecting shaft 521 and the main transmission structure 40 extend in the same direction, and along the extending direction of the first connecting shaft 521, the first transmission rod 522 and the first crank arm 51 are spaced apart on the first connecting shaft 521, further avoiding the first transmission rod 522 from interfering with the first crank arm 51 during the movement process, thereby affecting the normal movement of the first transmission rod 522 and the first conductive structure 211. At the same time, the above arrangement makes the structure of the auxiliary first transmission structure 52 simpler, easier to process and realize, and reduces the processing cost and difficulty of the linkage disconnector.

[0045] In this embodiment, the first transmission rod 522 is located above the first crank arm 51 with a preset space between the two to avoid motion interference between the two.

[0046] Optionally, the incoming busbar 25 and the outgoing busbar 26 of each isolated body 20 are located on the same side or different sides of the conductive structure group 21. In this way, the above arrangement makes the busbar incoming and outgoing modes of each isolated body 20 more diverse to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff.

[0047] In this embodiment, the incoming busbar 25 and the outgoing busbar 26 of each isolation body 20 are located on the same side of the conductive structure group 21 to achieve a U-shaped busbar connection.

[0048] In this embodiment, the power output device 30 is located below all the isolation bodies 20. In this way, the above-mentioned position setting facilitates the staff to operate the power output device 30, improves the user experience, and reduces the difficulty of operation.

[0049] like Figure 2 and Figure 3 As shown, the first conductive structure 211 includes a first conductive body 2111 and a first connecting portion 2112 disposed on the first conductive body 2111, and the first transmission structure 52 also includes a second connecting shaft 523. The second connecting shaft 523 is penetrated through the first connecting portion 2112, and the second end of the first transmission rod 522 is pivotally connected to the second connecting shaft 523. In this way, the above arrangement ensures that the first transmission rod 522 can drive the first conductive structure 211 to rotate, thereby improving the transmission reliability of the first transmission rod 522.

[0050] like Figure 3 As shown, the second transmission structure 53 includes a third connecting shaft 531 and a second transmission rod 532. The third connecting shaft 531 is arranged on the first connecting portion 2112 and is spaced apart from the second connecting shaft 523. The first end of the second transmission rod 532 is connected to the third connecting shaft 531, and the second end of the second transmission rod 532 is pivotally connected to the second conductive structure 212. In this way, the above arrangement ensures that the first conductive structure 211 and the second conductive structure 212 rotate synchronously and in opposite directions, so as to realize the opening and closing functions of the isolation body 20.

[0051] like Figure 2 and Figure 3As shown, the second conductive structure 212 includes a second conductive body 2121 and a second connecting portion 2122 disposed on the second conductive body 2121, and the second transmission structure 53 also includes a fourth connecting shaft 533, the fourth connecting shaft 533 is penetrated on the second connecting portion 2122, and the second end of the second transmission rod 532 is pivotally connected to the fourth connecting shaft 533. Among them, the first connection position of the second transmission rod 532 and the third connecting shaft 531 and the second connection position of the second transmission rod 532 and the fourth connecting shaft 533 are located at the same height. In this way, the above arrangement ensures that the second transmission rod 532 can drive the second conductive structure 212 to rotate, thereby improving the transmission reliability of the second transmission rod 532.

[0052] In this embodiment, the extension direction of the first transmission rod 522 and the extension direction of the second transmission rod 532 are both parallel to the horizontal plane and have a height difference. In this way, during the rotation of the main transmission structure 40, the above arrangement avoids motion interference between the first transmission rod 522 and the second transmission rod 532 to affect the transmission reliability and stability of the auxiliary transmission assembly 50.

[0053] like Figure 3 and Figure 5 As shown, each isolation body 20 also includes two insulators 27, and the two insulators 27 are arranged one by one with the two conductive structures. Each conductive structure is installed on the base 24 through the corresponding insulator 27. The terminal 213 of each conductive structure is a plate-type reverse L-shaped aluminum casting, and the conductive arm 214 of each conductive structure is a groove-shaped aluminum, and the contact bracket 215 and the contact finger bracket 216 are special-shaped aluminum. The contact 22 is a round-edged copper busbar, the contact finger 23 is a self-supporting copper material, and the spring sheet 217 is a stainless steel plate

[0054] Optionally, the contact 22 and the contact finger 23 are separable conductive parts, and the conductive surface at the contact point between the two is graphene-plated with silver or conventionally plated with silver.

[0055] Optionally, the insulators 27 are made of ceramic, silica gel, or glass, with two insulators per pole and six in total for three poles.

[0056] Optionally, the power output device 30 is a manually operable electric mechanism.

[0057] Embodiment 2

[0058] The linkage disconnector in the second embodiment is different from that in the first embodiment in that the incoming busbar and the outgoing busbar are arranged at different positions.

[0059] like Figure 6 As shown, the incoming busbar 25 and the outgoing busbar 26 of each isolation body 20 are located on different sides of the conductive structure group 21 to achieve an N-shaped busbar connection mode.

[0060] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0061] The linkage disconnector includes three isolation bodies, a power output device, a main transmission structure and an auxiliary transmission assembly. The three isolation bodies are arranged at intervals along the height direction, and each isolation body includes a conductive structure group, a contact and a contact finger. The conductive structure group includes two conductive structures that rotate synchronously and in opposite directions. The contact is arranged on one conductive structure, and the contact finger is arranged on the other conductive structure. The power output device is connected to the main transmission structure to drive the main transmission structure to rotate. The auxiliary transmission assembly is arranged on the main transmission structure, and the main transmission structure drives the two conductive structures of the conductive structure group to rotate through the auxiliary transmission assembly, so that each isolation body is in a closed state in which the two conductive structures rotate to insert the contact into the contact finger and an open state in which the two conductive structures rotate to separate the contact and the contact finger. In this way, the three isolation bodies are arranged at intervals along the height direction, that is, the three isolation bodies are respectively located at different heights, thereby reducing the overall footprint of the linkage disconnector, solving the problem of a large footprint of the three-pole disconnector in the prior art, improving the versatility of the linkage disconnector, and making its use place unrestricted.
