[0032] In the present application, unless otherwise specified, the orientation words such as "up, down" are generally directed to the directions shown in the drawings, or are directed to the vertical, perpendicular or gravity directions; similarly, for the convenience of understanding and description, "left, right" are generally directed to the left and right shown in the drawings; "inner, outer" refer to the inner and outer relative to the contour of each component, but the above orientation words are not used to limit the present application.

[0033] In order to solve the problem that the busbar insulation method increases the labor intensity of workers in the prior art, the present application provides a busbar insulation device.

[0034] As Figures 1 to 4As shown, the busbar insulation device comprises an insulation assembly 10 and a bottom plate 20. The insulation assembly 10 comprises a base plate 11, two oppositely arranged insulation parts 12, an elastic part 13 and an operation part 14, at least part of each insulation part 12 movably penetrates in the base plate 11; the first end of each insulation part 12 is connected with the elastic part 13, the second ends of the two insulation parts 12 are oppositely arranged, and the operation part 14 is arranged on at least one insulation part 12 to adjust the distance between the second ends of the two insulation parts 12 through the operation part 14. Wherein, the busbar insulation device has a disassembly state and an insulation state, when the busbar insulation device is in the disassembly state, the bottom plate 20 and the second end of at least one insulation part 12 form a busbar disassembly opening; when the busbar insulation device is in the insulation state, the bottom plate 20 is connected with the second ends of the two insulation parts 12 to form a busbar installation space with the two insulation parts 12.

[0035] By applying the technical scheme of the embodiment, the busbar insulation device has a disassembly state and an insulation state, when insulation protection is needed for the busbar, the operation part 14 is operated to adjust the distance between the second ends of the two insulation parts 12 through the operation part 14, so that the bottom plate 20 and the second end of at least one insulation part 12 form a busbar disassembly opening, and the busbar can enter the busbar insulation device through the busbar disassembly opening, at this time, the busbar insulation device is in the disassembly state. After the busbar is installed in the busbar insulation device, the operation part 14 is loosened, so that the bottom plate 20 is connected with the second ends of the two insulation parts 12 and forms a busbar installation space with the two insulation parts 12, at this time, the busbar insulation device is in the insulation state.

[0036] Compared with the prior art of wrapping the line with insulating tape, plastic sleeve or insulating rubber tube, the busbar insulation device in the embodiment makes the installation and disassembly process of the busbar more convenient, improves the work efficiency in the occasion of maintaining or replacing the busbar, and further solves the problem of increasing the labor intensity of workers in the busbar insulation mode in the prior art.

[0037] As shown in the figure, Figure 3 The insulation assembly 10 is multiple, and the multiple insulation assemblies 10 are arranged at intervals along the extension direction of the busbar. The busbar insulation device further comprises an elastic structure 40, which is arranged between adjacent two insulation assemblies 10 and connected with the two insulation assemblies 10. Wherein, the extension direction of the elastic structure 40 is consistent with the extension direction of the busbar. In this way, the above-mentioned arrangement of the elastic structure 40 makes the busbar insulation device have good bending ability, which can better fit the curved busbar line. At the same time, the elastic structure 40 can play the role of shock absorption and vibration absorption, avoiding the damage of vibration to the busbar and the insulation device, prolonging the service life of the busbar insulation device, and being especially suitable for the environment in which the busbar needs to bear large mechanical stress in the power system.

[0038] As shown in the figure, Figure 2As shown, the substrate 11 comprises a substrate body 111 and a protruding portion 113. The substrate body 111 has a first mounting recess 112, and at least part of the insulating portion 12 is slidably arranged in the first mounting recess 112. The protruding portion 113 is arranged on one side of the substrate body 111 and has a second mounting recess 114, and the elastic portion 13 is arranged in the second mounting recess 114. In this way, the above arrangement ensures that the insulating portion 12 can slide relative to the substrate 11, so that the busbar insulation device can be freely switched between the insulation state and the disassembly state. At the same time, the above arrangement makes the structure of the substrate 11 simpler, easier to process and implement, and reduces the processing cost and difficulty of the busbar insulation device.

[0039] Specifically, when it is necessary to insulate and protect the busbar, the operating portion 14 is simply pulled to move the insulating portion 12 towards the protruding portion 113, thereby increasing the distance between the second ends of the two insulating portions 12, so that the busbar disassembly opening is formed between the bottom plate 20 and the second end of at least one insulating portion 12, and the busbar insulation device can be directly buckled outside the circuit through the busbar disassembly opening, which is simple and convenient to install.

[0040] As shown, Figure 2 Each insulating portion 12 comprises an arc-shaped strip 121 and an arc-shaped insulating plate 122. The first end of the arc-shaped strip 121 is connected to the end of the elastic portion 13. The second end of the arc-shaped strip 121 is connected to the first end of the arc-shaped insulating plate 122, and the second end of the arc-shaped insulating plate 122 forms the second end of the insulating portion 12. The center line of the arc-shaped strip 121 is coaxially arranged with the central axis of the arc-shaped insulating plate 122. In this way, the above arrangement makes the structure of the insulating portion 12 simpler, easier to process and implement, and reduces the processing cost and difficulty of the insulating portion 12, thereby reducing the overall processing cost of the busbar insulation device.

[0041] In the present embodiment, the arc-shaped insulating plate 122 is arranged below the arc-shaped strip 121, and the busbar disassembly opening is formed between the lower ends of the two arc-shaped insulating plates 122. When installing, there is no need to find and arrange the head of the circuit. The arc-shaped strip 121 is simply pulled to move towards the inside of the protruding portion 113, which will drive the arc-shaped insulating plate 122 to move upwards, thereby increasing the busbar disassembly opening, and the busbar insulation device can be directly buckled outside the circuit through the busbar disassembly opening, which is simple and convenient to install.

[0042] Specifically, the center line of the arc-shaped strip 121 is coaxially arranged with the central axis of the arc-shaped insulating plate 122, which can ensure the centration of the busbar during installation, avoid the decline of insulation performance due to improper installation, effectively ensure the normal operation of the power equipment, and avoid electrical faults.

[0043] As shown, Figure 2As shown, the second mounting recess 114 is a first arc-shaped slot, and the insulating assembly 10 further comprises a first limiting part 15 and a second limiting part 16. The first limiting part 15 is arranged in the first arc-shaped slot. The second limiting part 16 is arranged on the first end of the arc-shaped strip 121, and the first end of the arc-shaped strip 121 extends into the first arc-shaped slot, so that the first limiting part 15 and the second limiting part 16 are limited and matched. In this way, the above-mentioned limiting and matching ensures the stability of the insulating part 12 during operation, avoids damage to the busbar insulation device caused by improper operation, and is suitable for various power equipment that needs to be frequently operated, such as switch cabinets, distribution boxes, etc., which can significantly improve the safety and efficiency of operation and reduce the failure rate of equipment caused by operation errors.

[0044] In this embodiment, the arc-shaped strip 121 and the first arc-shaped slot are limited and matched by the first limiting part 15 and the second limiting part 16, so as to improve the assembly stability between the insulating part 12 and the base plate 11, and prevent them from being separated from each other on the premise that they can move relative to each other.

[0045] Optionally, the operating part 14 is a ring-shaped handle arranged on the arc-shaped strip 121 and located outside the first mounting recess 112. The first mounting recess 112 is a second arc-shaped slot or an arc-shaped hole, and the center line of the second arc-shaped slot or the arc-shaped hole is coaxially arranged with the center line of the first arc-shaped slot, so as to switch the busbar insulation device between the disassembled state and the insulated state by moving the ring-shaped handle in the direction close to the first arc-shaped slot. In this way, the above-mentioned arrangement makes the structure of the operating part 14 and the first mounting recess 112 simpler, easier to process and implement, and reduces the processing cost and difficulty of the operating part 14.

[0046] As shown in Figure 3 and Figure 4 The busbar insulation device further comprises an insulating plate group 30 arranged between two adjacent insulating assemblies 10, and the insulating plate group 30 comprises two first insulating plates 31, a plurality of second insulating plates 32, and a plurality of insulating columns 33. Each first insulating plate 31 is connected with the base plate 11 of each insulating assembly 10. The plurality of second insulating plates 32 are located between the two first insulating plates 31. At least one insulating column 33 is arranged between the first insulating plate 31 and the second insulating plate 32, and at least another insulating column 33 is arranged between two adjacent second insulating plates 32. In this way, the above-mentioned arrangement of the insulating plate group 30 improves the overall insulation reliability and structural stability of the busbar insulation device.

[0047] Specifically, the above-mentioned arrangement of the insulating plate group 30 further enhances the insulation performance of the busbar, effectively prevents electrical short circuit, improves the operation safety of the power system, and reduces the maintenance cost.

[0048] Optionally, the first insulating plate 31 is made of rubber or silicone.

[0049] Optionally, the second insulating plate 32 is made of rubber or silicone.

[0050] Optionally, the insulating column 33 is made of rubber or silicone.

[0051] As shown in Figure 1 The busbar insulation device further comprises an insulating tape 70 and a shielding plate 50. One end of the insulating tape 70 is bonded to the insulating assembly 10 and the insulating plate set 30. The other end of the insulating tape 70 is bonded to the shielding plate 50. The shielding plate 50 is made of a flexible material. Alternatively, the shielding plate 50 is adapted to the outer surface of the insulating portion 12. In this way, the above-mentioned arrangement not only enhances the insulation effect of the busbar insulation device, but also prevents dust and foreign matter from entering, effectively protects the power equipment from the external environment, prolongs the service life, and reduces the maintenance cost.

[0052] Optionally, the elastic structure 40 comprises a plurality of first elastic rings 41 and a plurality of second elastic rings 42. Each adjacent two first elastic rings 41 are connected by a second elastic ring 42, and each adjacent two second elastic rings 42 are connected by a first elastic ring 41. The inner diameter of the first elastic ring 41 is smaller than the inner diameter of the second elastic ring 42. In this way, the above-mentioned arrangement makes the elastic structure 40 have a corrugated structure with wave crests and wave troughs. The first elastic ring 41 forms the wave trough, and the second elastic ring 42 forms the wave crest. The wave crests and wave troughs are arranged alternately, so that the elastic structure 40 has greater extension and contraction ability, can extend or contract automatically with the bending degree of the substrate 11, and has better protection ability.

[0053] Optionally, the elastic portion 13 is a spring; and / or, each insulating portion 12 is provided with a sliding block 60, and the bottom plate 20 is provided with a sliding groove. When the busbar insulation device is in an insulating state, the sliding block 60 extends into the sliding groove and is limited and stopped by the sliding groove. The sliding block 60 is made of rubber or silicone, and the bottom plate 20 is made of rubber or silicone. In this way, the above-mentioned arrangement makes the structure of the elastic portion 13 simpler, easier to process and implement, and reduces the processing cost and difficulty of the busbar insulation device. At the same time, the above-mentioned arrangement makes the disassembly of each insulating portion 12 and the bottom plate 20 easier and simpler, and reduces the disassembly difficulty of the two.

[0054] In this embodiment, the sliding block 60 and the bottom plate 20 are both supported by rubber and have a certain friction. Therefore, when the bottom plate 20 is inserted between the sliding blocks 60, it will not fall off. The design at this position also enables the bottom plate 20 to well fit the bending degree of the line.

[0055] In this embodiment, the working principle of the busbar insulation device is as follows:

[0056] In use, first pull up the operation part 14, the operation part 14 drives the pair of arc-shaped strips 121 to move into the convex part 113, and further drives the pair of arc-shaped insulating plates 122 to move upwards, the pair of arc-shaped insulating plates 122 will increase the space of the busbar dismounting port during the movement, and further can be buckled outside the circuit, and by analogy, the whole insulating assembly 10 can be buckled outside the circuit. The insulating assembly 10 is connected with the insulating plate group 30, so that the busbar insulating device has good bending performance, can be attached to the bending degree of the circuit, and can play a good protection effect while being quickly installed.
