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

[0034] like Figures 1 to 4As shown, the busbar insulation device includes an insulation assembly 10 and a bottom plate 20. The insulation assembly 10 includes a base plate 11, two insulating parts 12 arranged opposite to each other, an elastic part 13 and an operating part 14. At least part of each insulating part 12 can be movably inserted into the base plate 11; the first end of each insulating part 12 is connected to the elastic part 13, the second ends of the two insulating parts 12 are arranged opposite to each other, and the operating part 14 is arranged on at least one insulating part 12 to adjust the distance between the second ends of the two insulating parts 12 through the operating part 14. The busbar insulation device has a disassembly state and an insulation state. When the busbar insulation device is in the disassembly state, a busbar disassembly port is formed between the bottom plate 20 and the second end of at least one insulating part 12; when the busbar insulation device is in the insulation state, the bottom plate 20 is connected to the second ends of the two insulating parts 12 to form a busbar installation space around the two insulating parts 12.

[0035] By applying the technical solution of this embodiment, the busbar insulation device has a disassembly state and an insulation state. When the busbar needs to be insulated, the operating part 14 is operated to adjust the distance between the second ends of the two insulation parts 12 through the operating part 14, so that a busbar disassembly port is formed between the bottom plate 20 and the second end of at least one insulation part 12, and the busbar can enter the busbar insulation device through the busbar disassembly port. At this time, the busbar insulation device is in a disassembly state. After the busbar is installed in the busbar insulation device, the operating part 14 is released so that the bottom plate 20 is connected to the second ends of the two insulation parts 12 and surrounds the two insulation parts 12 to form a busbar installation space. At this time, the busbar insulation device is in an insulation state.

[0036] Compared with the prior art of wrapping the line with insulating tape, plastic sleeve or insulating hose, the busbar insulation device in this embodiment makes the installation and disassembly process of the busbar more convenient, improves the work efficiency in the maintenance or replacement of the busbar, and thus solves the problem that the busbar insulation method in the prior art increases the labor intensity of the staff.

[0037] like Figure 3 As shown, there are multiple insulating components 10, and the multiple insulating components 10 are arranged at intervals along the extension direction of the busbar. The busbar insulation device also includes an elastic structure 40, which is arranged between two adjacent insulating components 10 and connected to both insulating components 10. Among them, the expansion and contraction direction of the elastic structure 40 is consistent with the extension direction of the busbar. In this way, the above-mentioned setting of the elastic structure 40 enables the busbar insulation device to have good bending ability and can better fit the curved busbar line. At the same time, the elastic structure 40 can play a role in shock absorption and vibration absorption, avoiding damage to the busbar and the insulation device caused by vibration, and extending the service life of the busbar insulation device. It is particularly suitable for environments where the busbar in the power system needs to withstand greater mechanical stress.

[0038] like Figure 2As shown, the substrate 11 includes a substrate body 111 and a convex portion 113. The substrate body 111 has a first mounting recess 112, and at least part of the insulating portion 12 is slidably inserted into the first mounting recess 112. The convex 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 switch freely 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 realize, and reduces the processing cost and difficulty of the busbar insulation device.

[0039] Specifically, when the busbar needs to be insulated, it is only necessary to pull the operating part 14 to move the insulating part 12 toward the side of the protrusion 113, thereby increasing the distance between the second ends of the two insulating parts 12, so that a busbar disassembly port is formed between the bottom plate 20 and the second end of at least one insulating part 12, so that the busbar insulation device can be directly buckled on the outside of the line through the busbar disassembly port, and the installation is simple and convenient.

[0040] like Figure 2 As shown, each insulating part 12 includes 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 part 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 part 12. The center line of the arc-shaped strip 121 is coaxially arranged with the center axis of the arc-shaped insulating plate 122. In this way, the above arrangement makes the structure of the insulating part 12 simpler, easier to process and realize, reduces the processing cost and difficulty of the insulating part 12, and further reduces the overall processing cost of the busbar insulating device.

[0041] In this embodiment, the arc-shaped insulating plate 122 is arranged below the arc-shaped bar 121, and a busbar disassembly opening is formed between the lower ends of the two arc-shaped insulating plates 122. During installation, there is no need to find and organize the head of the line. Only the operating part 14 needs to be turned. When the arc-shaped bar 121 moves toward the inside of the convex part 113, the arc-shaped insulating plate 122 will be driven to move upward, thereby enlarging the busbar disassembly opening, making it convenient to directly buckle the busbar insulation device on the outside of the line through the busbar disassembly opening, and the installation is simple and convenient.

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

[0043] like Figure 2As shown, the second mounting recess 114 is a first arc-shaped groove, and the insulating assembly 10 further includes a first limiting portion 15 and a second limiting portion 16. Among them, the first limiting portion 15 is arranged in the first arc-shaped groove. The second limiting portion 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 groove, so that the first limiting portion 15 and the second limiting portion 16 are limited and matched. In this way, the above-mentioned limiting cooperation ensures the stability of the insulating portion 12 during operation, avoids damage to the busbar insulation device caused by improper operation, is suitable for various power equipment that requires frequent operation, such as switch cabinets, distribution boxes, etc., can significantly improve the safety and efficiency of operation, and reduce the equipment failure rate caused by operational errors.

[0044] In this embodiment, the arc strip 121 and the first arc groove are limited by the first limiting portion 15 and the second limiting portion 16 to improve the assembly stability between the insulating portion 12 and the substrate 11 and prevent the two from detaching from each other while ensuring that they can move relative to each other.

[0045] Optionally, the operating portion 14 is an annular handle, which is arranged on the arc strip 121 and outside the first mounting recess 112. The first mounting recess 112 is a second arc groove or an arc hole, and the center line of the second arc groove or the arc hole is coaxially arranged with the center line of the first arc groove, so that the busbar insulation device can be switched between the disassembly state and the insulation state by moving the annular handle in a direction close to the first arc groove. In this way, the above arrangement makes the structure of the operating portion 14 and the first mounting recess 112 simpler, easier to process and realize, and reduces the processing cost and difficulty of the operating portion 14.

[0046] like Figure 3 and Figure 4 As shown, the busbar insulation device also includes an insulation plate group 30 arranged between two adjacent insulation components 10, and the insulation plate group 30 includes two first insulation plates 31, a plurality of second insulation plates 32 and a plurality of insulation columns 33. Among them, each first insulation plate 31 is connected to the substrate 11 of each insulation component 10. The plurality of second insulation plates 32 are located between the two first insulation plates 31. At least one insulation column 33 is arranged between the first insulation plate 31 and the second insulation plate 32, and at least another insulation column 33 is arranged between two adjacent second insulation plates 32. In this way, the above-mentioned arrangement of the insulation 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, can effectively prevent electrical short circuits, improve the operational safety of the power system, and reduce maintenance costs.

[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] like Figure 1 As shown, the busbar insulation device also includes 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 group 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; or, the part of the shielding plate 50 that shields the insulating part 12 is adapted to the outer surface of the insulating part 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, can effectively protect the power equipment from the influence of the external environment, prolong its service life, and reduce maintenance costs.

[0052] Optionally, the elastic structure 40 includes a plurality of first elastic rings 41 and a plurality of second elastic rings 42, each two adjacent first elastic rings 41 are connected by a second elastic ring 42, and each two adjacent 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 arrangement makes the elastic structure 40 a pleated structure with crests and troughs, the first elastic ring 41 forms the trough, the second elastic ring 42 forms the crest, and the crests and troughs are arranged alternately, so that the elastic structure 40 has a greater extension and contraction ability, can extend or contract automatically according to the bending degree of the substrate 11, and has a better protection ability.

[0053] Optionally, the elastic part 13 is a spring; and / or, a slider 60 is provided on the second end of each insulating part 12, and the bottom plate 20 has a slide groove; when the busbar insulation device is in an insulating state, the slider 60 extends into the slide groove and stops with the slide groove; the slider 60 is made of rubber or silicone, and the bottom plate 20 is made of rubber or silicone. In this way, the above arrangement makes the structure of the elastic part 13 simpler, easier to process and realize, and reduces the processing cost and difficulty of the busbar insulation device. At the same time, the above arrangement makes the disassembly and assembly of each insulating part 12 and the bottom plate 20 easier and simpler, and reduces the difficulty of disassembly and assembly of the two.

[0054] In this embodiment, the slider 60 and the base plate 20 are both supported by rubber and have a certain friction force. Therefore, when the base plate 20 is inserted between the sliders 60, it will not fall off. This design can also make the base plate 20 fit the curvature of the circuit well.

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

[0056] When in use, first pull the operating part 14 upward, the operating part 14 drives the pair of arc strips 121 to move into the convex part 113, and then drives the pair of arc insulating plates 122 to move upward. The pair of arc insulating plates 122 will increase the space of the busbar disassembly port during the movement, and then it can be buckled outside the line. By analogy, the entire insulating assembly 10 can be buckled outside the line. Among them, the insulating assembly 10 is connected with the insulating plate group 30, so that the busbar insulating device has good bending performance, can fit the curvature of the line, and can be quickly installed while playing a good protective effect.

[0057] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0058] The busbar insulation device includes an insulation component and a base plate.

At least part of each insulating part can be movably inserted into the base plate. The first end of each insulating part is connected to the elastic part, the second ends of the two insulating parts are arranged opposite to each other, and the operating part is arranged on at least one insulating part so as to adjust the distance between the second ends of the two insulating parts through the operating part. In this way, the busbar insulation device has a disassembly state and an insulation state. When the busbar needs to be insulated and protected, the operating part is operated to adjust the distance between the second ends of the two insulating parts through the operating part so that a busbar disassembly port is formed between the base plate and the second end of at least one insulating part. The busbar can enter the busbar insulation device through the busbar disassembly port. At this time, the busbar insulation device is in a disassembly state. After the busbar is installed in the busbar insulation device, the operating part is released so that the base plate is connected to the second ends of the two insulating parts and surrounds the two insulating parts to form a busbar installation space. At this time, the busbar insulation device is in an insulation state.
