The short-circuit current will trigger the operation of the circuit breaker or fuse, causing the line to disconnect, thereby causing a power outage. At the same time, the high current and high temperature generated by the short circuit may damage the equipment in the low-voltage distribution box, such as circuit breakers, contactors, terminal blocks, etc.

[0004] (2) Safety risks: Short circuit accidents may cause sparks and arc discharges, increasing the risk of electric shock to workers.

For those skilled in the art of the present application, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0041] In view of the aforementioned shortcomings of the existing technology, the applicant, drawing upon years of extensive practical experience and expertise in the design and manufacture of such products, combined with the application of academic theory, has actively engaged in research and innovation, hoping to create a technology that can address these shortcomings. Through continuous research and design, and through repeated trial production and refinement, the present invention has been developed, which possesses truly practical value.

[0042] Please refer to Figure 1 The embodiment of the present invention provides a novel low-voltage substation overhead busbar protection and isolation device. This device has a unique and rational structural design. Specifically, it includes several carefully crafted insulating baffles 1. These insulating baffles 1 do not exist in isolation, but are detachably connected in sequence through a specific connection method. This detachable connection design is not arbitrary, but is carefully considered to meet the installation, disassembly, and maintenance requirements in different practical scenarios, providing great convenience for subsequent operation and maintenance work.

[0043] A closer look at the internal structure of each insulating baffle 1 reveals a more sophisticated split-type design. Each insulating baffle 1 is cleverly composed of a removably connected upper portion 101 and lower portion 102. This split-type design is significant in several ways. Firstly, it simplifies processing and quality control during the manufacturing process. Secondly, during installation and use, it allows for flexible disassembly and assembly based on actual needs, significantly improving operational convenience and flexibility.

[0044] Crucially, both the upper and lower halves 101, 102, have been meticulously designed, each featuring a precisely defined semicircular hole. When properly connected and assembled, the two semicircular holes perfectly align to form a complete, perfectly defined circular hole. The precise size and shape of this circular hole, precisely calculated and designed, ensures the smooth passage of the overhead busbar. This design not only ensures the secure passage of the overhead busbar through the device, but also establishes a stable and reliable connection between the entire protective isolation device and the overhead busbar.

[0045] The novel low-voltage substation overhead busbar protection and isolation device proposed in the embodiment of the present invention adopts a structure of several detachably connected insulating baffles 1, and further subdivides each insulating baffle 1 into a detachable upper half 101 and a lower half 102, thereby forming a full-circular hole for the overhead busbar to pass through. This series of ingenious designs has significant technical advantages and practical value. In actual application, the device can form a solid and effective physical barrier, effectively preventing all kinds of small animals from climbing along the overhead busbar and entering the low-voltage substation. Once small animals cannot enter the low-voltage substation, the possibility of them contacting live parts and grounded parts is fundamentally avoided, thereby greatly reducing the incidence of short-circuit faults caused by small animals. Short-circuit faults are a common and serious problem in power systems. Once they occur, they often cause damage to electrical equipment and interruption of power supply, bringing great inconvenience and loss to production and life. The application of this device can significantly reduce the risk of electrical failures and power outages, reduce the expensive repair costs and replacement costs caused by equipment damage, and thus effectively reduce economic losses.

[0046] At the same time, the structural design of the new protective isolation device fully considers various needs in practical applications, and has the outstanding characteristics of simple structure and easy installation. Its simple structure allows workers to complete the installation task quickly and accurately without complicated operating procedures and professional skills during the installation process. Moreover, in daily maintenance and replacement work, due to the detachable nature of the device, workers can easily inspect, repair and replace various components, which greatly shortens maintenance time and improves work efficiency. This convenient maintenance and replacement method further ensures the safety and reliability of the low-voltage substation during long-term operation, and provides a strong guarantee for the stable operation of the power system. In summary, the new low-voltage substation overhead busbar protective isolation device provided by the embodiment of the present invention has important innovative value and practical significance both at the technical level and the application level.

[0047] Please refer again Figure 1 In one implementation of this embodiment, the connection design of the insulating baffles 1 is highly scientific and reasonable. Specifically, between each two adjacent insulating baffles 1, a locking structure 2 is innovatively used to achieve a detachable connection.

[0048] The design of this locking mechanism 2 contains many subtle details. From the perspective of connection stability, the locking mechanism 2 has been carefully designed and optimized. Its unique shape and interlocking method ensure that the two adjacent insulating baffles 1 form a tight and stable whole after connection. In the actual operating environment of the low-voltage substation, it is subject to various external forces such as wind and equipment vibration. The locking mechanism 2 can effectively resist the interference of these external forces, ensuring that the connection between the insulating baffles 1 will not easily loosen or fall off, thereby providing a solid guarantee for the stability of the entire protective isolation device.

[0049] From the perspective of detachability, the design of the locking structure 2 fully considers the actual needs of installation, maintenance and replacement. When the insulating baffle 1 needs to be installed, the staff can easily connect the two adjacent insulating baffles 1 together quickly and accurately through the locking structure 2, without the need to use complex tools or perform tedious operations, which greatly improves the installation efficiency. In the subsequent maintenance and replacement process, when a certain insulating baffle 1 needs to be inspected, repaired or replaced, it is only necessary to unlock the locking structure 2 through simple operations, separate the adjacent insulating baffles 1, and then perform the corresponding processing on the target insulating baffle 1. After the processing is completed, it is reconnected through the locking structure 2. The whole process is convenient and fast, greatly saving time and labor costs.

[0050] Furthermore, the upper and lower halves 101 and 102 of each insulating barrier 1 are also detachably connected using a locking mechanism 2. This design also offers significant advantages. During the manufacturing process, separating the insulating barrier 1 into the upper and lower halves 101 and 102 and connecting them via the locking mechanism 2 reduces production complexity and costs. Separately producing the upper and lower halves 101 and 102 makes it easier to control precision and quality compared to producing them as a whole, and each halves can be designed and optimized separately to meet specific needs.

[0051] In actual use, when installing or repairing the overhead busbar, workers can easily open the upper portion 101 by undoing the locking structure 2 between the upper and lower portions 101, exposing the overhead busbar and facilitating related operations. Once the operation is complete, the upper portion 101 is securely connected to the lower portion 102 via the locking structure 2, restoring the integrity of the protective isolation device. This design not only ensures the protective isolation device's effective barrier function against small animals, but also greatly facilitates the operation and maintenance of the power system.

[0052] To sum up, in this implementation of the present embodiment, whether it is the connection between adjacent insulating baffles 1 or the connection between the upper and lower halves of each insulating baffle 1, a locking structure 2 is used to achieve a detachable connection. This design fully reflects the perfect combination of innovation and practicality, and provides strong support for the stable operation and convenient maintenance of the new low-voltage substation overhead busbar protection isolation device.

[0053] Please refer to Figure 2 In one implementation of this embodiment, a more refined and targeted optimization design is performed on the insulating baffle 1. Specifically, barb structures 3 are specially added to the surface and edge of the insulating baffle 1.

[0054] The design of this barb structure 3 is not random, but has been rigorously considered and demonstrated. From a functional point of view, the barb structure 3 has a unique protective effect. In the actual operating environment of the low-voltage substation, small animals often try to climb along the overhead busbar to enter the substation, and the insulating baffle 1 is a key component to prevent small animals from entering. The added barb structure 3 is like building a "spike defense line" on the insulating baffle 1. When small animals come into contact with the insulating baffle 1, the barb structure 3 will cause obstruction and discomfort to their bodies. During the climbing process, once the body parts of small animals touch these sharp barbs, they will find it difficult to continue climbing due to pain and discomfort, and may even actively give up climbing behavior, thereby effectively preventing small animals from going further into the low-voltage substation along the insulating baffle 1.

[0055] From a structural design perspective, the barb structure 3 is tightly integrated with the surface and edges of the insulating barrier 1, forming an organic whole. This integration not only ensures the stability of the barb structure 3, preventing it from falling off or damaging during long-term use, but also prevents it from negatively impacting the overall structure and performance of the insulating barrier 1. This ensures that the insulating barrier 1 maintains excellent insulation performance, preventing safety hazards such as leakage during power system operation.

[0056] Furthermore, the material of the barb structure 3 has been carefully selected, typically made of a material with a certain strength and toughness. This material not only ensures that the barb structure 3 will not easily bend or break when touched by small animals, thereby maintaining its protective function, but also can adapt to different environmental conditions, such as temperature and humidity changes, to a certain extent, ensuring that it can maintain stable performance in various harsh environments.

[0057] In summary, the addition of barbed structures 3 to the surface and edges of the insulating barrier 1 in this embodiment is a highly innovative and practical design. It further enhances the insulating barrier 1's ability to protect against small animals, effectively reducing the risk of small animals entering the low-voltage substation and causing short-circuit failures, thus providing a more reliable guarantee for the safe and stable operation of the low-voltage substation.

[0058] In one implementation of this embodiment, the insulating baffle 1 is carefully designed and optimized from multiple key aspects to ensure that it can perform excellent performance in the overhead busbar protection and isolation scenario in the low-voltage substation area.

[0059] In terms of material selection:

[0060] The insulating baffle 1 is made of high-quality materials with flame retardant and weather-resistant properties. Specifically, these materials include one or more of epoxy resin, polycarbonate or silicone rubber. Epoxy resin has excellent insulation properties, mechanical strength and good chemical stability, and can effectively resist the erosion of chemical substances in the external environment. At the same time, its flame retardant properties can greatly reduce the risk of fire and maintain structural integrity even in high temperature environments. Polycarbonate is known for its high strength, high transparency and excellent impact resistance. It can maintain good physical properties under complex climatic conditions, such as strong winds and heavy rains, and provide reliable structural support for the insulating baffle 1. Silicone rubber has excellent high and low temperature resistance, flexibility and electrical insulation properties, can work normally in a very wide temperature range, and can effectively prevent the occurrence of leakage. By selecting one or more combinations of these materials, the insulating baffle 1 can adapt to various harsh natural environments and complex electrical working conditions, ensuring long-term stable operation.

[0061] In terms of full circle hole design:

[0062] A flexible buffer layer is specially provided on the inner wall of the circular hole. This design is based on the meticulous protection of the overhead busbar. During the operation of the power system, the overhead busbar may produce slight vibrations or displacements due to various factors. Without the protection of the flexible buffer layer, frequent friction and collisions will occur between the busbar surface and the inner wall of the circular hole. In the long run, it will cause wear on the busbar surface, thereby affecting its electrical performance and service life. The flexible buffer layer has excellent elasticity and shock absorption properties. It can effectively absorb the energy generated by busbar vibration and reduce the friction between the busbar and the inner wall of the circular hole, thereby preventing wear on the busbar surface and ensuring the stability and safety of power transmission.

[0063] In terms of external surface marking:

[0064] To significantly enhance the visibility of the insulation barrier 1 at night or in low-visibility environments, a reflective coating or warning signs are carefully applied to its exterior. The reflective coating produces a strong reflection when exposed to light, making the insulation barrier 1 clearly visible in the dark, alerting workers to its presence and preventing accidental collisions. Warning signs, with their striking colors and specific patterns, convey danger or caution, further enhancing their safety warning function. Whether conducting nighttime inspections or operating in inclement weather, these signs provide clear visual guidance for workers, ensuring safe and orderly work.

[0065] In terms of edge drainage design:

[0066] Considering the potential adverse effects of rainwater on the insulating baffle 1, a clever gutter structure has been designed along its edges. During rainfall, rainwater tends to accumulate at the edges of the insulating baffle 1. Prolonged accumulation not only increases the weight of the insulating baffle 1 and affects its structural stability, but can also cause water to seep into the interior, compromising its electrical performance. The gutter structure quickly directs accumulated rainwater away, preventing it from stagnating at the edges. This effectively prevents various issues caused by rainwater accumulation and ensures the proper functioning of the insulating baffle 1 in humid environments.

[0067] In terms of edge reinforcement design:

[0068] A reinforcing rib structure is added to the edge of the insulating baffle 1. The reinforcing rib structure is a common and effective design method for enhancing structural strength. By providing reinforcing ribs at the edge, the bending resistance and impact resistance of the edge of the insulating baffle 1 can be significantly improved, making it less likely to deform or be damaged when subjected to external forces. In the actual operation of the low-voltage substation, the insulating baffle 1 may be affected by various external forces such as wind and collisions. The reinforcing rib structure can effectively enhance its structural stability, extend its service life, and ensure the continued effectiveness of the protective isolation function.

[0069] In terms of anti-slip surface design:

[0070] To facilitate installation and removal, the surface of the insulating barrier 1 is provided with an anti-slip texture. When installing or removing the insulating barrier 1, workers need to directly contact the surface with their hands. If the surface is too smooth, hands can easily slip, increasing the difficulty and safety risks of operation. The anti-slip texture increases the friction between the hand and the surface of the insulating barrier 1, allowing workers to hold the insulating barrier 1 more firmly during operation, improving accuracy and safety, and reducing accidents caused by operational errors.

[0071] In terms of color warning design:

[0072] The insulating barrier 1 is set to one of yellow, red, or orange, which are highly visually recognizable and alerting. In power work environments, yellow typically represents attention and warning, red symbolizes danger and prohibition, and orange also has a strong warning effect. Selecting these colors for the insulating barrier 1 can attract the attention of workers from a distance, reminding them that a protective isolation device is present and requires careful operation, thereby further enhancing the visual warning effect and effectively preventing safety accidents caused by negligence.

[0073] To sum up, this implementation method in this embodiment has comprehensively improved the performance and safety of the insulating baffle 1 through careful consideration and optimization of materials, structural design, identification settings, etc., providing strong guarantee for the reliable protection of the overhead busbar in the low-voltage substation area.

[0074] Although the terms "insulating baffle" and "locking structure" are frequently used in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.

[0075] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application.
