[0002] An electrical control cabinet is a set of switchgear, measuring instruments, protective devices, and auxiliary equipment assembled in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, facilitate maintenance, and not endanger personnel or surrounding equipment. During normal operation, circuits can be connected or disconnected using manual or automatic switches. Electrical control cabinets are generally equipped with grounding copper busbars to achieve the effect of wiring connection.

[0003] Currently, common grounding copper busbar connection structures for electrical cabinets mostly use fixed-length copper busbars, which are connected to the equipment inside the cabinet and the external grounding system through bolts, welding, or other methods. However, fixed-length grounding copper busbars have limitations. In actual production and installation, different specifications and models of electrical cabinets, as well as differences in the layout of equipment inside the cabinet, require different lengths of grounding copper busbars. In some special application scenarios, such as when it is necessary to temporarily adjust the grounding system layout or to cope with sudden equipment installation needs, fixed-length grounding copper busbars cannot quickly meet the actual needs, seriously affecting the installation and maintenance efficiency of the electrical system. Therefore, this utility model proposes a novel solution. Utility Model Content

[0028] Please see Figure 1-4 This utility model provides a technical solution: an optimized connection structure for grounding copper busbars in an electrical cabinet, including a first grounding copper busbar 1, a second grounding copper busbar 2 slidably sleeved on the surface of the first grounding copper busbar 1, the second grounding copper busbar 2 having a square tubular structure, an adjustment component, the adjustment component being disposed on the second grounding copper busbar 2, the adjustment component including a second mounting bolt 12, the second mounting bolt 12 being disposed inside the second grounding copper busbar 2, a plurality of first mounting holes 5 being opened on the surface of the first grounding copper busbar 1, a second mounting hole 6 being opened on the front surface of the second grounding copper busbar 2, a third mounting hole 7 being opened on the rear surface of the second grounding copper busbar 2, the second mounting bolt 12 being disposed inside the second mounting holes 6 and the third mounting holes 7 on the surface of the second grounding copper busbar 2, a connecting ring 13 being fixedly connected to the surface of the second mounting bolt 12, the connecting ring 13 being snapped into the third mounting hole 7, the first grounding copper busbar 1 and the second grounding copper busbar 2 being fixed by the second mounting bolt 12 and the connecting ring 13, and the second mounting bolt 12 penetrating through the corresponding first mounting hole 5 on the surface of the first grounding copper busbar 1.

[0029] A first mounting bolt 9 is provided inside the first mounting hole 5 on the surface of the first grounding copper busbar 1. A washer 10 and a first grounding wire 11 are sleeved on the surface of the first mounting bolt 9. The first grounding wire 11 is fixed to the first grounding copper busbar 1 by the first mounting bolt 9. There are multiple first mounting bolts 9, washer 10 and first grounding wire 11 on their surfaces.

[0030] There are two second grounding copper busbars 2, which are symmetrically arranged on the left and right sides of the first grounding copper busbar 1. There are multiple second mounting bolts 12 and connecting rings 13. The surfaces of the multiple second mounting bolts 12 are also fitted with washers 10 and first grounding wires 11.

[0031] A second grounding wire 14 is sleeved on the surface of the second mounting bolt 12 near the first grounding copper busbar 1. The second grounding wire 14 and multiple first grounding wires 11 are fixed to the second grounding copper busbar 2 by the second mounting bolt 12.

[0032] The lower ends of the two second grounding copper busbars 2 are fixedly connected to the first copper busbar connecting plate 3 and the second copper busbar connecting plate 4. The surfaces of the first copper busbar connecting plate 3 and the second copper busbar connecting plate 4 are provided with multiple fourth mounting holes 8.

[0033] When using this device, the length of the grounding copper busbar needs to be adjusted to adapt to the layout of the equipment inside the electrical cabinet when facing different specifications of electrical cabinets. Since the surface of the first grounding copper busbar 1 is slidably fitted with the second grounding copper busbar 2, which has a square tubular structure, and there is an adjustment component on each of the left and right sides of the first grounding copper busbar 1, the second mounting bolt 12 in the adjustment component is set inside the second grounding copper busbar 2, passes through the second mounting hole 6 and the corresponding first mounting hole 5, and the connecting ring 13 fixed on its surface is engaged with the third mounting hole 7. When the second mounting bolt 12 is separated from the second grounding copper busbar 2, the second grounding copper busbar 2 can slide along the first grounding copper busbar 1. After selecting a suitable first mounting hole 5, tighten the second mounting bolt 12, and use the engagement of the connecting ring 13 with the third mounting hole 7 to fix the first and second grounding copper busbars, so as to realize the flexible adjustment of the length of the grounding copper busbar.

[0034] Electrical equipment is connected to a grounding copper busbar via a first grounding wire 11. The surface of the first grounding copper busbar 1 has multiple first mounting holes 5, and each first mounting hole 5 is fitted with a first mounting bolt 9. The first mounting bolt 9 passes through the washer 10 and the first grounding wire 11 in sequence and is then tightened to fix the first grounding wire 11 onto the first grounding copper busbar 1, thus achieving the grounding connection of the electrical equipment. At the same time, the second grounding copper busbar 2 also has multiple second mounting bolts 12, and its surface is also fitted with washer 10 and the first grounding wire 11, further increasing the number of electrical equipment that can be connected and ensuring the reliability of grounding.

[0035] When an electrical appliance leaks current, the current is conducted through the first grounding wire 11. One end of the first grounding wire 11 is connected to the electrical appliance, and the other end is fixed to the first grounding copper busbar 1 by the first mounting bolt 9. The current is conducted from the first grounding copper busbar 1 to the second grounding copper busbar 2 because the first and second grounding copper busbars are fixedly connected by the second mounting bolt 12 and the connecting ring 13. Then, the current is conducted through the second grounding copper busbar 2 to the second grounding wire 14. One end of the second grounding wire 14 is fixed to the second grounding copper busbar 2 by the second mounting bolt 12, and the other end is connected to the ground, ultimately leading the current to the ground and protecting the safety of personnel and equipment.

[0036] By setting up two second grounding wires 14, the resistance values ​​of the first grounding copper busbar 1 and the second grounding copper busbar 2 are reduced, further increasing safety.

[0037] The first copper busbar connecting plate 3 and the second copper busbar connecting plate 4 are fixedly connected to the lower ends of the two second grounding copper busbars 2, and the multiple fourth mounting holes 8 opened on their surfaces provide the possibility of extended installation of the grounding copper busbars; by installing bolts and other connecting parts in the fourth mounting holes 8, the grounding copper busbars can be more securely connected to other components of the electrical cabinet, enhancing the stability of the grounding system, or connecting other auxiliary grounding devices to optimize the grounding effect.
