[0001] The utility model relates to the field of busbar systems, in particular to a single-phase stacked busbar system. Background Art

[0002] A single-phase busbar usually has three wires, one end of the first line is the main line input end, and the other end is the main line output end, one end of the second line is a bypass, one end is an input end, and the other end is an output end; one end of the third line is the main line output end, and the other end is the main line input end; the main line input end and the main line output end of the first and third lines are usually assembled on the same side; it is usually used in electrical equipment such as switch cabinets, electrical cabinets, and USP cabinets; single-phase busbars usually use exposed copper bars. In order to avoid short circuits caused by mutual contact between the three wires, air insulation is usually used for isolation, that is, the output busbar, the output busbar, and the bypass busbar are isolated from each other.

[0003] At present, the three lines of a single-phase busbar are usually arranged in the height direction, and the space for installing the single-phase busbar in electrical equipment such as switch cabinets, electrical cabinets, and USP cabinets is narrow, that is, the height dimension is small; and the air insulation method requires a sufficient distance between the busbars to prevent high voltage and high current from breaking through the air; this results in the reserved installation space of some electrical equipment being unable to meet the installation of the one-way busbar; and it is not convenient for assemblers to install the single-phase busbar in a small space. Utility Model Content

[0004] The purpose of the utility model is to provide a single-phase stacked busbar system to address the above-mentioned problems, in which the three lines in a single-phase busbar are stacked together, making installation more convenient without the need to install each group of busbars separately; at the same time, the purpose of minimizing the height space occupied is achieved.

[0008] Furthermore, the top plate and the two side plates are detachably connected via bolts.

[0009] Furthermore, two ends of the single-phase busbar are overlapping portions, and the overlapping portions are located outside the insulating sleeve.

[0010] Furthermore, the geometric shape of the single busbars is a U-shape having a bottom edge and two side arms, the single busbars abut against each other in the height direction, the side arms are distributed along the horizontal direction, and the width of the bottom edges is different.

[0011] Furthermore, the bottom edges are all located inside the shell, and the side arms are all extended out of the shell.

[0012] Furthermore, the bottom width of the single-phase busbars decreases gradually, and the busbars are arranged in sequence from top to bottom and from outside to inside of the U-shaped structure in height.

[0013] Furthermore, a support frame is provided inside each of the single-phase busbars, and the support frame is fixed inside the outer shell.

[0014] Furthermore, the support frame is detachably connected to the outer shell by bolts.

[0015] Furthermore, both ends of the single-phase busbar are provided with limiting members, and the limiting members are fixed in the shell.

[0025] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0026] Any feature disclosed in this specification, unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0027] Example 1

[0028] like Figure 1-Figure 3 As shown, a single-phase stacked busbar system includes a housing 1 and a single-phase busbar 2 assembled in the housing 1. The housing 1 stacks the single-phase busbar 2 to form a complete module, which can be pre-assembled and installed in electrical equipment to achieve modular installation, making the installation of the single-line busbar more convenient, without the need to install three lines one by one on the electrical equipment, thereby improving installation efficiency.

[0029] In this embodiment, as described in the background technology, the single-phase busbar 2 is a general term for three wires, which include three wires. The three wires of the single-phase busbar 2 are all covered with insulating sleeves 5, that is, each wire is covered with an insulating sleeve 5, and the three wires are isolated from each other by the insulating sleeves 5, changing the conventional air insulation method so that the single-phase busbars 2 can be abutted against each other through the insulating sleeves 5, thereby effectively reducing the space required for air insulation, and then reducing the space reserved for the installation of the single-phase busbar 2 by the electrical equipment, thereby achieving the purpose of reducing the volume of the electrical equipment and increasing applicability.

[0030] Example 2

[0031] Based on Example 1, a specific implementation method that can be implemented is further proposed.

[0032] A feasible implementation manner is that the housing 1 is provided with a mounting hole 13 for mounting on an electrical device, so as to facilitate installation of the entire system in the electrical device; specifically, the housing 1 is fixed in the electrical device by passing the screw rod of the bolt through the mounting hole 13 and then tightening it with a nut; the single-line busbar is installed in the housing 1, that is, the single-phase busbar 2 is assembled in the electrical device.

[0033] A feasible implementation manner, the housing 1 is composed of three U-shaped plates, which are actually sheet metal parts formed by die-casting, and have a bottom surface and side edges. One of the three U-shaped plates serves as a top plate 12, and the remaining two serve as side plates 11; the mounting holes 13 are arranged on the sides of the side plates 11, so as to facilitate the installation of the housing 1 on the electrical equipment without position interference.

[0034] It should be noted that the housing 1 is composed of three sides, which can not only ensure the air circulation in the housing 1 but also isolate dust from falling into the interior of the housing 1 .

[0035] In a feasible implementation, the top plate 12 and the two side plates 11 are detachably connected by bolts, that is, the side of the top plate 12 and the bottom surface of the side plate 11 are both provided with connection holes, and the screw rods of the bolts pass through the corresponding connection holes and are then engaged by nuts to achieve detachable connection. The detachable connection between the top plate 12 and the two side plates 11 makes the housing 1 detachable, which is convenient for replacing the single busbar 2 installed in the housing 1, and recycling the housing 1.

[0036] A feasible implementation manner, the two ends of the single-phase busbar 2 are overlapping parts 23, the middle part of the single-phase busbar 2 is located in the outer shell 1, and the overlapping part 23 is located outside the outer shell 1, so that the single-phase busbar 2 can be overlapped with other busbars of the electrical equipment; the overlapping part 23 is located outside the insulating sleeve 5 to prevent the insulating sleeve 5 from closing the overlapping part 23 and affecting the overlapping work; overlapping holes are provided at the overlapping part 23 to facilitate the overlapping of the single-phase busbar 2.

[0037] Example 3

[0038] Based on any one of the implementations in Examples 1-2, a feasible implementation is further proposed.

[0039] In a feasible implementation manner, the geometric shape of each line of the single-phase busbar 2 is a U-shape having a bottom edge 21 and two side arms 22, which can be formed by stamping a copper busbar; the single-phase busbars 2 abut against each other in the height direction, saving the layout space in the height direction; the side arms 22 are distributed along the horizontal direction, and the widths of the bottom edges 21 are different, avoiding spatial position interference between the overlapping parts 23 when overlapping.

[0040] Furthermore, the bottom edges 21 are all located inside the housing 1 , and the side arms 22 are all extended out of the housing 1 from the bottom of the housing 1 .

[0041] Furthermore, the width of the bottom edge 21 of the single busbar 2 decreases gradually, and is arranged in sequence from top to bottom in height and from the outside to the inside of the U-shaped structure; that is, the first line has the largest width; the second line has a medium width and is located inside the first line; and the third line has the smallest width and is located inside the second line.

[0042] A feasible implementation manner is that a support frame 4 is provided inside the single-phase busbar 2, and the support frame 4 corresponds to supporting the three wires in the single-phase busbar 2, limiting the height position of the single-phase busbar 2 in the outer shell 1, and ensuring the stability of the position of the three wires of the single-phase busbar 2; the support frame 4 is fixed in the outer shell 1.

[0043] Furthermore, the support frame 4 is detachably connected to the housing 1 by bolts, so as to facilitate the disassembly and installation of the single-phase busbar 2 .

[0044] In a feasible implementation manner, both ends of the single-phase busbar 2 are provided with limit members 3, and the limit members 3 are fixed in the housing 1. The limit members 3 limit the left and right positions of the single-phase busbar 2 to prevent the single-phase busbar 2 from moving left and right.

[0045] Furthermore, the stopper 3 is detachably connected to the housing 1 via bolts, so as to facilitate the disassembly and installation of the single-phase busbar 2 .

[0046] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
