[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] like Figure 1 to Figure 4 As shown, this embodiment provides a busbar clamp, which includes a busbar clamp body 1 and a protruding structure 2. The busbar clamp body 1 is provided with a busbar through-hole 11, and a plurality of protruding structures 2 are arranged at intervals on the hole wall of the busbar through-hole 11 along the first direction X and / or the second direction Y. The busbar through-hole 11 is used for the busbar 3 to pass through, and the plurality of protruding structures 2 are used to abut against the busbar 3. The busbar clamp body 1 is an insulating member, and the first direction X and the second direction Y are perpendicular. When the busbar 3 is inserted into the busbar through-hole 11, the outer peripheral wall of the busbar 3 abuts against the protruding structure 2 in the busbar through-hole 11, which reduces the abutting area between the busbar 3 and the inner peripheral wall of the busbar through-hole 11, thereby facilitating the heat dissipation of the busbar 3.

[0036] Specifically, when the busbar is inserted into the busbar through-hole, the first direction X is consistent with the thickness direction of the busbar, and the second direction Y is consistent with the width direction of the busbar.

[0037] Optionally, a plurality of protruding structures 2 are detachably arranged on the two side walls of the busbar through hole 11 along the first direction X. In this embodiment, the protruding structures 2 are detachably connected, and then protruding structures 2 of different thicknesses can be selected according to the thickness of the busbar 3, so that the busbar clamp can be suitable for busbars 3 of different thickness specifications. Specifically, the protruding structures 2 are made of insulating material.

[0038] Optionally, the two side walls of the busbar through hole 11 along the first direction X are respectively provided with limiting holes at intervals; the raised structure 2 includes an adjusting column 21 and a raised platform 22, one end of the adjusting column 21 is connected to the raised platform 22, and the other end of the adjusting column 21 is inserted into a plurality of limiting holes correspondingly one by one, and the adjusting column 21 is screwed with the limiting holes. In this embodiment, since the raised structure 2 is provided on the two side walls of the busbar through hole 11 along the first direction X, the relative position of the adjusting column 21 along the axial direction of the limiting hole and the busbar clamp body 1 can be adjusted, thereby adjusting the spacing of the raised structure 2 on the two side walls of the busbar through hole 11 along the first direction X to adapt to the installation and fixation of busbars 3 of different thicknesses. Specifically, the limiting hole can be a threaded hole, and the adjusting column 21 can be a stud, and the relative position of the raised platform 22 and the busbar clamp body 1 can be adjusted by screwing the adjusting column 21 in the adjusting hole. Specifically, the raised platform 22 may be made of insulating rubber material, which can increase the pressure and friction of the raised platform 22 on the busbar 3. In other embodiments, the raised platform 22 may also be made of insulating hard plastic material.

[0039] Optionally, a groove 23 is formed on one side of the raised platform 22 away from the adjusting column 21. In this embodiment, the groove 23 can reduce the contact area between the raised platform 22 and the busbar 3, thereby facilitating heat dissipation of the busbar 3.

[0040] Optionally, convex ribs 12 are respectively provided on the two side walls of the busbar through-hole 11 along the second direction Y. In this embodiment, after the busbar 3 is passed through the busbar through-hole 11, the two side walls of the busbar 3 along the second direction Y are respectively abutted against the two convex ribs 12, thereby avoiding the two side walls of the busbar through-hole 11 along the second direction Y from being fitted with the two side walls of the second direction Y, further reducing the abutment area between the busbar 3 and the inner wall of the busbar through-hole 11, thereby facilitating the heat dissipation of the busbar 3.

[0041] In addition, the size of the busbar through hole 11 along the first direction X and the size along the second direction Y are applicable to busbars of various specifications, such as busbar 3 with a thickness of 3mm, 4mm, 5mm, 6mm, 8mm, etc. Since the cost of the busbar 3 is relatively high, according to cost calculation, under the condition of equal current carrying capacity and ensuring the temperature rise of the busbar 3, a busbar 3 with a small thickness and a small width is selected, which can reduce the conductor cross-sectional area, save conductor materials, and reduce costs. For example: the original 125*5 busbar 3 can be replaced with a 120*4 busbar 3, saving 23% of materials.

[0042] Optionally, the two side walls of the busbar clamp body 1 along the third direction Z are respectively provided with protrusions 13, and the two ends of the busbar through-hole 11 pass through the protrusions 13, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other. In this embodiment, after the busbar 3 is passed through the busbar through-hole 11, the third direction Z is consistent with the length direction of the busbar 3. The above arrangement can extend the length of the busbar through-hole 11 along the length direction of the busbar 3, thereby improving the stability of supporting the busbar 3. Specifically, a protrusion 13 is provided near each busbar through-hole 11, and the protrusion 13 is rectangular.

[0043] Optionally, four groups of busbar through-holes 11 are provided, each group is provided with at least one busbar through-hole 11, and the four groups of busbar through-holes 11 are arranged in a rectangular array. In this embodiment, the installation arrangement of the busbar 3 adopts a rectangular arrangement, which reduces the space occupied by the busbar 3 in the cabinet depth compared to a single row arrangement. In other embodiments, when the busbar 3 is a three-phase busbar, three groups of busbar through-holes 11 are provided, and the connection lines of the three groups of busbar through-holes 11 are triangular.

[0044] Optionally, an inclined guide surface structure is provided at the opening where the busbar through hole 11 intersects with the outer surface of the busbar clamp body 1. In this embodiment, the inclined guide surface structure guides the busbar 3 and facilitates the insertion of the busbar 3 into the busbar through hole 11.

[0045] Optionally, a plurality of weight-reducing holes are provided on the busbar clamp body 1 , and this arrangement can reduce the overall weight of the busbar clamp body 1 .

In this embodiment, the plugging of the positioning protrusion 14 and the positioning groove 41 can realize the rapid positioning of the busbar clamp body 1 and the mounting beam 4. Specifically, the busbar clamp body 1 and the mounting beam 4 are fixedly connected by bolts, wherein the side wall of the busbar clamp body 1 opposite to the mounting beam 4 is pre-embedded with a threaded insert, and the bolt passes through the mounting beam 4 and is screwed with the threaded insert.

[0047] Optionally, the two side walls of the busbar clamp body 1 along the third direction Z are respectively provided with support parts 15, and the two support parts 15 are respectively in contact with the mounting beam 4. In this embodiment, the two support parts 15 can improve the stability of the relative fixation between the busbar clamp body 1 and the mounting beam 4, and the busbar 3 with larger electric power can be placed in the busbar through-hole 11 close to the mounting beam 4, so that the whole system has better stability.

[0048] Optionally, the busbar system further includes a support column 5, which is detachably connected to the mounting crossbeam 4, which is detachably connected to a side wall of the busbar clamp body 1 along the second direction Y, and which is detachably connected to a side wall of the busbar clamp body 1 along the first direction X.
