[0039] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0041] As described above, the busbar system in the switchgear is the main way to introduce electric energy from the power supply system into equipment and loads. Multiple busbar units in the busbar system need to be connected as a whole through gaskets to avoid loose connection and affect the conductivity of the busbar system. Operators will adjust the busbar units of each phase busbar according to the usage of the switchgear. However, the gaskets cannot be adjusted correspondingly according to the adjustment of the phase busbar, and the gaskets are easy to fall off in the distribution cabinet. Embodiments of the present disclosure provide a busbar system 100 and a distribution cabinet to at least partially solve the above problems. Hereinafter, the principles of the present disclosure will be described in conjunction with Figures 1 to 11 Describe the principles of the present disclosure.

[0042] Figure 1 FIG. shows a schematic structural view of the main gasket 3 according to some embodiments of the present disclosure. Figure 2 FIG. shows a schematic structural view of the sub-gasket 4 according to some embodiments of the present disclosure. Figure 3 FIG. shows an installation schematic view of the fastener 5 and the mating member 6 according to some embodiments of the present disclosure. Figure 4 FIG. shows a schematic structural view of the busbar system 100 according to some embodiments of the present disclosure. As Figures 1 to 4 shown, the busbar system 100 described herein generally includes a mounting frame 1, a phase busbar 2, at least one main gasket 3, at least one sub-gasket 4, a fastener 5, and a mating member 6.

[0043] Referring to Figure 4 , in some embodiments, the mounting frame 1 includes multiple groups of mounting holes 11. Each group of mounting holes 11 includes multiple mounting holes 11, and the multiple mounting holes 11 include at least two rows arranged side by side along the first direction X and at least two columns arranged side by side along the second direction Y. The first direction X is perpendicular to the second direction Y. Each phase busbar 2 includes multiple busbar units 21, and the multiple busbar units 21 are arranged in some of the mounting holes 11 of the corresponding group of mounting holes 11.

[0044] Continuing to refer to Figures 1 to 4 , in some embodiments, at least one main gasket 3 is located between adjacent busbar units 21 in the second direction Y, and at least one main gasket 3 can contact the corresponding busbar unit 21. At least one sub-gasket 4 is coupled to at least one main gasket 3. Each sub-gasket 4 is disposed at a position corresponding to the mounting holes 11 in the corresponding group of mounting holes 11 that are not occupied by the multiple busbar units 21. That is, the sub-gasket 4 can at least partially overlap with the corresponding mounting holes 11.

[0045] It should be noted that, continuing to refer to Figures 3 to 4 , in some embodiments, each sub-gasket 4 can contact the adjacent busbar units 21 in the first direction X; or each sub-gasket 4 can be spaced apart from the adjacent busbar units 21 in the first direction X, which will not be elaborated here.

[0046] According to an embodiment of the present disclosure, when the busbar monomers 21 are not installed in some of the mounting holes 11 of a set of mounting holes 11, the combination form of the main gasket 3 and the sub-gasket 4 can be correspondingly adjusted according to the adjustment method of the phase busbar 2, so that the main gasket 3 and the sub-gasket 4 can be assembled in any combination according to actual requirements. In addition, since each main gasket 3 is located between adjacent busbar monomers 21 and the sub-gasket 4 is coupled to the corresponding main gasket 3, it is possible to effectively prevent the sub-gasket 4 from falling off the main gasket 3.

[0047] Return to reference Figures 1 to 4 , in some embodiments, each main gasket 3 may include a mating hole 32. Correspondingly, each sub-gasket 4 may include a mating groove 42, and the mating hole 32 may be aligned with the corresponding mating groove 42. The fitting 6 can pass through the corresponding mating hole 32 and the corresponding mating groove 42. A channel 101 is provided between adjacent rows of mounting holes 11 in the first direction X, and the fitting 6 can pass through the channel 101 to fasten the main gasket 3, the sub-gasket 4, and the phase busbar 2, thereby preventing the main gasket 3 and the sub-gasket 4 from falling off.

[0048] It should be noted that the number of the mating holes 32 and the fittings 6 is related to the number of rows of each set of mounting holes 11. For example, refer to Figure 3 , in some embodiments, when each set of mounting holes 11 includes three rows, the mating holes 32 and the fittings 6 are each provided in pairs.

[0049] Continue to refer to Figure 3 , in some embodiments, the end of each main gasket 3 may be correspondingly arranged with the mounting holes 11 in the outer row in the first direction X of a corresponding set of mounting holes 11. It can be understood that when each set of mounting holes 11 includes two rows, both rows of each set of mounting holes 11 can be regarded as the outer rows.

[0050] During the process of arranging the busbar monomers 21, generally, the busbar monomers 21 are preferably arranged in the mounting holes 11 in the middle row, and the busbar monomers 21 are not arranged in the mounting holes 11 in the relatively outer rows. Therefore, it is necessary to arrange the sub-gaskets 4 at positions corresponding to the mounting holes 11 in the outer rows. In addition, the sub-gaskets 4 at positions corresponding to the mounting holes 11 in the outer rows are prone to fall off due to weak support. Based on this, continue to refer to Figure 1 , Figure 2 and Figure 4, Further, each main gasket 3 may include a pair of first connection structures 31. The pair of first connection structures 31 are each adjacent to an end of the corresponding main gasket 3 in the first direction X. Correspondingly, each sub-gasket 4 may include a second connection structure 41. The pair of first connection structures 31 can each be aligned with the corresponding second connection structure 41 to dispose the corresponding sub-gasket 4 on at least one side of each main gasket 3. Thus, the main gasket 3 can be firmly connected to the corresponding sub-gasket 4.

[0051] In summary, since the end of each main gasket 3 is correspondingly arranged with the mounting holes 11 in the corresponding outer row, and the pair of first connection structures 31 are each adjacent to the end of the corresponding main gasket 3 in the first direction X; therefore, in the case where the busbar monomer 21 is not arranged in the mounting holes 11 in the outer row, the sub-gasket 4 can be arranged at the position corresponding to the unoccupied mounting holes 11, thereby avoiding the problem of virtual connection.

[0052] The first connection structure 31 and the second connection structure 41 according to the embodiments of the present disclosure can be various types of connection structures that are currently known or will be available in the future, and the embodiments of the present disclosure do not limit this. For example, continuing to refer to Figures 1 to 4 , in some embodiments, the pair of first connection structures 31 may each include a first connection hole 311. The second connection structure 41 may include a second connection hole 411 that is aligned with the corresponding first connection hole 311. The fastener 5 can cooperate with the first connection hole 311 and the second connection hole 411 to realize the connection between the main gasket 3 and the sub-gasket 4.

[0053] The fastener 5 according to the embodiments of the present disclosure can be various types of fasteners 5 that are currently known or will be available in the future, and the embodiments of the present disclosure do not limit this. For example, referring to Figure 3 , in some embodiments, the fastener 5 can be a countersunk head screw. One end of the fastener 5 can be located in the second connection hole 411, and the other end of the fastener 5 can be located in the corresponding first connection hole 311 or the corresponding second connection hole 411. It can be understood that since both ends of the fastener 5 are located in the corresponding holes, the fastener 5 cannot interfere with the phase busbar 2.

[0054] Hereinafter, the busbar system 100 of the present disclosure will be exemplarily described mainly in the case where each group of mounting holes 11 includes three rows arranged side by side in the first direction X. The cases where each group of mounting holes 11 includes two rows, four rows or more are similar and will not be elaborated here.

At least one main gasket 3 may include a first main gasket 33. The first main gasket 33 is located between adjacent busbar monomers 21 in the second direction Y, and the first main gasket 33 may be in contact with the busbar monomers 21 on both of its sides. The ends of the first main gasket 33 may be correspondingly arranged with the mounting holes 11 in the outer row.
