Technical Field

[0001] This utility model relates to the field of switchgear technology, specifically to a grounding anti-interference device for high and low voltage switchgear. Background Technology

[0002] High and low voltage switchgear is a key device in power systems used for power distribution, control and protection. It is a complete set of power distribution equipment assembled with primary equipment (such as circuit breakers and disconnectors) and secondary equipment (such as relays and instruments) according to a certain circuit scheme, and is used to control, protect and monitor power lines and equipment.

[0003] The existing grounding copper busbars inside high and low voltage switchgear need to be moved during installation to avoid affecting the installation of internal components. Moving the busbars requires disassembly and reassembly, which is cumbersome and requires manual tightening or loosening of bolts. This is especially inconvenient and time-consuming in narrow spaces. Therefore, there is a need to provide a grounding copper busbar that can be quickly replaced and disassembled to improve the convenience of disassembly and reassembly. Utility Model Content

[0004] The purpose of this utility model is to provide a grounding anti-interference device for high and low voltage switchgear to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0006] Switch cabinet and cabinet door, wherein the cabinet door is hinged to one side of the switch cabinet;

[0007] The mounting assembly includes mounting rods, sliding grooves, fixing holes, and grounding copper busbars. The mounting rods are fixed to both sides of the bottom surface inside the switch cabinet. The sliding grooves are opened in the center of the mounting rods. Eleven fixing holes are opened at equal intervals on one side of the outer surface of the mounting rods. The grounding copper busbars are placed on the upper surfaces of the two mounting rods.

[0008] Furthermore, a bolt passes through the middle of the grounding copper busbar, and a connecting wire passes through the bolt.

[0009] Furthermore, sliders are fixed on both sides of the lower surface of the grounding copper busbar, and the sliders slide through the groove.

[0010] Furthermore, a mounting hole is provided on one side of the outer surface of the slider, and a spring is fixed inside the mounting hole.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this utility model is a grounding anti-interference device for high and low voltage switchgear, comprising:

[0028] Switch cabinet 11, cabinet door 12, the cabinet door 12 is hinged to one side of switch cabinet 11;

[0029] The mounting assembly includes a mounting rod 21, a slide groove 22, fixing holes 23, and a grounding copper busbar 24. The mounting rod 21 is fixed on both sides of the bottom surface inside the switch cabinet 11. The slide groove 22 is opened in the center of the mounting rod 21. Eleven fixing holes 23 are opened at equal intervals on one side of the outer surface of the mounting rod 21. The grounding copper busbar 24 is placed on the upper surface of the two mounting rods 21.

[0030] Switchgear 11 serves as the main support for power equipment, used for installing and protecting the equipment. The switchgear 11 described in this article is the same model as the anti-interference device for a high and low voltage switchgear in patent number CN218005603U, and the internal components are installed in the same positions. The mounting rod 21 serves as the support track for the grounding copper busbar 24, and the slide groove 22 provides a guide channel for the slider 25, restricting the movement trajectory of the grounding copper busbar 24 and preventing its lateral deviation. The fixing hole 23 serves as the locking target for the locking post 28, used to fix the final position of the grounding copper busbar 24. The grounding copper busbar 24 serves as the grounding conductor of switchgear 11, conducting the leakage current from the equipment casing, frame, and other parts to the ground, ensuring personal safety and stable equipment operation.

[0031] A bolt passes through the middle of the grounding copper busbar 24, and a connecting wire 29 passes through the bolt. Slider 25 is fixed on both sides of the lower surface of the grounding copper busbar 24, and the sliding of the slider 25 passes through the slide groove 22. A mounting hole 26 is opened on one side of the outer surface of the slider 25. A spring 27 is fixed inside the mounting hole 26. A locking post 28 is fixed at the end of the spring 27, and the locking post 28 is located in the mounting hole 26. The end of the locking post 28 extends into the corresponding fixing hole 23.

[0032] The slider 25 is embedded in the groove 22 of the mounting rod 21, serving as the sliding carrier of the grounding copper busbar 24. The mounting hole 26 accommodates the spring 27 and the locking post 28, providing installation space and movement guidance for both. The spring 27 stores elastic potential energy, providing a pushing force to the locking post 28 in the direction of the fixing hole 23 to achieve automatic locking. The locking post 28, as the core component of the locking mechanism, restricts the movement of the grounding copper busbar 24 after being inserted into the fixing hole 23, thus fixing its position. The connecting wire 29 is connected to the internal components of the switch cabinet 11.

[0033] Working principle:

[0034] When the position of the grounding copper busbar 24 needs to be changed, the operator only needs to press the locking post 28 inward, so that the spring 27 is compressed in the mounting hole 26, and the locking post 28 is removed from the fixing hole 23. Then, push the grounding copper busbar 24 to adjust its position. When the grounding copper busbar 24 moves to the appropriate position, under the elastic force of the spring 27, the spring 27 will quickly restore its deformation, causing the locking post 28 to lock into the corresponding fixing hole 23, so that the position of the grounding copper busbar 24 can be quickly adjusted.

[0035] This step simply requires pressing the locking pin 28 to release the fixing hole 23, eliminating the need for tools and significantly reducing disassembly and assembly time. It can be completed by a single person, reducing reliance on professional tools and making it especially suitable for confined spaces.

[0036] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0037] The fastening assembly includes a fixing bracket 31, a threaded hole 32, a threaded rod 33, and a bearing 34. The fixing bracket 31 is fixed to the upper surface of the grounding copper busbar 24, and the threaded hole 32 is opened in the middle of the fixing bracket 31. The threaded rod 33 is threaded through the threaded hole 32. The bearing 34 is rotatably mounted on the lower end of the threaded rod 33. A fixing plate 35 is fixed to the lower surface of the bearing 34, and a circular hole 36 is opened on the outer surface of the fixing plate 35, through which a bolt passes.

[0038] The fixing bracket 31 provides support for the threaded hole 32 and the threaded rod 33. The threaded hole 32 maintains the pressed position of the fixing plate 35 through the self-locking effect of the thread, preventing loosening. The threaded hole 32 pushes the fixing plate 35 down or up through rotational movement, realizing the clamping or release of the connecting line 29. The bearing 34 allows the threaded rod 33 to maintain stable rotation when subjected to axial force, preventing tilting or jamming. The pressing or lifting action is realized through the linkage between the bearing 34 and the threaded rod 33.

[0039] Working principle:

[0040] When the connecting wire 29 is connected to the grounding copper busbar 24, simply rotate the threaded rod 33. The threaded rod 33 rotates in the threaded hole 32 and rotates synchronously in the bearing 34, which drives the fixing plate 35 to move downward. The fixing plate 35 presses the connecting wire 29 tightly onto the grounding copper busbar 24. With just one adjustment, all the connecting wires 29 can be pressed tightly.

[0041] This step allows for simultaneous clamping of multiple lines through single-point adjustment, improving maintenance efficiency. Rotating a single threaded rod 33 is sufficient to clamp all connecting lines 29 simultaneously, eliminating the need to tighten bolts or screws one by one, thus significantly improving efficiency.

[0042] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
