Description

Technical Field

[0001] This utility model belongs to the field of electronic equipment technology, and in particular relates to an insulating card plate assembly for 10kV equipment remote sensing. Background Technology

[0002] In power system operation and maintenance, insulation resistance testing of 10kV equipment is a crucial step in ensuring safe operation. Its purpose is to use a megohmmeter to test the insulation performance of the equipment and determine if there are potential hazards such as leakage or insulation aging. However, the current structural design of 10kV equipment (such as switches and switchgear) presents several practical challenges to the resistance testing operation:

[0003] 10kV equipment switchgear is typically a closed or semi-closed space with a compact internal structure. The gap between the lower contact box and the baffle is narrow. When performing insulation resistance tests, operators need to connect the test lead to the equipment test point and simultaneously fix the baffle to prevent it from shaking and interfering with the operation. In traditional operation, the operator needs to hold the baffle with one hand to maintain its position and operate the test lead with the other hand. This "two-handed" operation mode has significant drawbacks in confined spaces:

[0004] On the one hand, limited operating space restricts limb movement, making it easy for hands to come into accidental contact with live parts or metal casings of the equipment. This poses a high risk of electric shock, especially when the insulation performance of the equipment is not clearly defined. On the other hand, when the baffle lacks reliable fixation, it is prone to displacement due to external forces (such as operator hand tremors or slight equipment vibrations), which may lead to poor contact of the measuring line, affecting the accuracy of the test data, or even causing arc discharge, resulting in burns to personnel or damage to the equipment.

[0005] Furthermore, existing auxiliary tools are mostly general-purpose insulating baffles, not designed for the specific gap dimensions of 10kV equipment, resulting in the following problems: First, their simple structure makes them unable to form a stable engagement with the lower contact box and baffle of the equipment, still requiring manual assistance for fixation; second, the insulation performance of the materials is inconsistent, with some tools failing the insulation resistance test of a 2500V megohmmeter, making it difficult to meet the safety requirements of high-voltage equipment; third, installation and disassembly are cumbersome, with poor adaptability and low universality among different models of 10kV equipment, increasing the operational burden on maintenance personnel.

[0006] Based on this, the present invention provides a novel insulating card plate assembly for 10kV equipment remote sensing to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of this utility model is to provide an insulating clamp assembly for 10kV equipment testing. The insulating clamp assembly adopts a combination structure of insulating insert and insulating clamp. Through the matching and cooperation of the plug and the through hole and the limiting effect of the locking part, a stable mechanical connection is formed. It can be reliably locked between the lower contact box and the baffle of the switch during 10kV equipment testing, thus physically blocking the direct contact path between personnel and live parts, reducing safety risks such as arc burns, and maximizing the personal safety of operators.

[0013] The width of the engaging portion is greater than the width of the insert portion, and after the insert portion is inserted into the through hole, the engaging portion can engage with the outer periphery of the through hole.

[0014] Furthermore, the insulating insert is in the shape of a rectangular plate.

[0015] Furthermore, the through hole is a strip-shaped through hole.

[0016] Furthermore, the insertion part and the engaging part are an integral structure.

[0017] Furthermore, the end edge of the insertion portion away from the engaging portion is chamfered, and the chamfer is provided on at least one side of the end edge.

[0018] Furthermore, the chamfer is provided on both sides of the end edge.

[0019] Furthermore, the width of the engaging portion is smaller than the width of the insulating insert.

[0020] Furthermore, anti-slip textures are provided on both walls of the engaging part.

[0021] Furthermore, the insulating insert is made of glass fiber reinforced epoxy resin material.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] In this utility model, an insulating clamp assembly for 10kV equipment vibration testing is used by first inserting the insulating plate into the narrow gap between the lower contact box and the baffle of the 10kV switch.

Due to size limitations, the engaging part can engage with the outer periphery of the through hole, forming a limiting fit, thus achieving... Figure 3 The locking mechanism shown in the diagram secures the entire insulating card assembly.

[0025] This utility model adopts a combination structure of insulating plug and insulating clamp. Through the matching and cooperation of the plug part and the through hole and the limiting effect of the clamping part, a stable mechanical connection is formed. It can be reliably clamped between the lower contact box and the baffle when 10kV equipment is tested. It physically blocks the direct contact path between personnel and live parts, reduces the safety risks such as arc burns, and can protect the personal safety of operators to the greatest extent.

[0026] Meanwhile, its snap-fit ​​design allows for quick installation and disassembly by a single person without the need for additional tools, solving the coordination problem of "holding the baffle with one hand and operating the measuring line with the other" in traditional operations, thus reducing the difficulty of operation and physical exertion.

[0033] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] The following is in conjunction with the appendix Figure 1 To be continued Figure 3 The present invention will be described in detail with reference to specific embodiments:

[0035] like Figures 1 to 3 As shown, this utility model provides an insulating card plate assembly for 10kV equipment vibration testing, which includes:

[0036] An insulating insert plate 1, wherein a through hole 10 is provided on the insulating insert plate 1;

[0037] Insulating plate 2, the insulating plate 2 includes a connected plug-in part 20 and a locking part 21;

[0038] The size of the plug-in part 20 is adapted to the size of the through hole 10, and the plug-in part 20 can be inserted into the through hole 10 to achieve plug-in cooperation between the two.

[0039] The width of the engaging part 21 is greater than the width of the inserting part 20, and after the inserting part 20 is inserted into the through hole 10, the engaging part 21 can engage with the outer periphery of the through hole 10 to form a limiting fit.

[0040] In this utility model, the insulating clamp assembly for 10kV equipment vibration testing is used by first inserting the insulating plate 1 into the narrow gap between the lower contact box and the baffle of the 10kV switch. Then, the insertion part 20 of the insulating clamp 2 is inserted into the through hole 10 of the insulating plate 1. Due to size limitations, the engaging part 21 engages with the outer periphery of the through hole 10, forming a limiting fit, thus achieving the desired effect. Figure 3 The locking mechanism shown in the diagram secures the entire insulating card assembly.

[0041] This invention employs a combination structure of an insulating insert plate 1 and an insulating clamp plate 2. A stable mechanical connection is formed through the fitting and engagement of the insert portion 20 and the through hole 10, and the limiting effect of the locking portion 21. This allows for reliable locking between the lower contact box and the baffle during 10kV equipment insulation testing, physically blocking direct contact between personnel and live parts, reducing safety risks such as arc burns, and maximizing operator safety. Simultaneously, its locking design enables quick installation and disassembly by a single person without additional tools, solving the coordination problem of "one hand holding the baffle and the other operating the testing line" in traditional operations, reducing operational difficulty and physical exertion. Furthermore, the component is made from only two insulating plates through simple processes such as drilling and cutting, resulting in low cost and reusability, reducing equipment maintenance and replacement costs. In addition, this insulating clamp plate assembly has a standardized structure, establishing a fixed operating procedure for protective measures, reducing the impact of human factors, facilitating its promotion across substations and among operators, and improving the standardization level of 10kV equipment insulation testing operations.

[0042] It should be noted that the insulating card assembly of this utility model has been widely used in relevant operations at Hangqiao Substation and Guoke Substation. After repeated verification, it can effectively improve personnel safety and eliminate safety hazards during various switching operations, and can fully meet daily operational needs.

[0043] Furthermore, in some specific embodiments, the insulating insert 1 is designed as a rectangular plate. Correspondingly, the through hole 10 is designed as a strip-shaped through hole. The elongated design of the strip-shaped through hole provides clearer guidance for the insertion of the plug part 20, reduces alignment deviation during the insertion process, and can reduce the difficulty of operation and improve installation efficiency, especially in scenarios with poor lighting or limited operating space.

[0044] In this embodiment, the method for manufacturing the insulating insert 1 is as follows:

[0045] Select an insulating board with a length of 15cm, a width of 15cm, and a thickness of 0.5cm. Make a through hole with a length of 8cm and a width of 1cm at the middle position, 1cm away from the edge, to complete the fabrication of insulating insert 1. The structure is simple and easy to manufacture.

[0046] Furthermore, in some specific embodiments, the plug-in part 20 and the engaging part 21 can be an integral structure or separate structures, such as snap-fit ​​connections or plug-in connections, to achieve the connection between the two. However, preferably, as in this embodiment, the plug-in part 20 and the engaging part 21 are an integral structure. In this embodiment, the processing of the insulating card plate 2 can be completed by cutting, eliminating the need for separate processing, assembly, and quality inspection of components required for separate structures, greatly simplifying the production process and reducing processing time and labor costs. At the same time, it reduces the material consumption of connecting components (such as snap-fit ​​assemblies), which can significantly improve economic efficiency in mass production. In addition, the connecting parts of separate structures (such as snap-fit ​​gaps and plug-in interfaces) may form small gaps due to insufficient assembly precision, which can easily accumulate dust, moisture, and other impurities during long-term use, affecting the overall insulation performance. The integral structure does not have such gaps, the continuity of the insulating material is better, and it can maintain a stable insulation resistance. When tested with a 2500V megohmmeter, it can ensure that the insulation performance meets the standards and meets the insulation protection requirements of 10kV high-voltage equipment.

[0047] Furthermore, in some specific embodiments, the end edge of the plug-in portion 20 away from the engaging portion 21 is formed with a chamfer 22, and the chamfer 22 is disposed on at least one side of the end edge. When the plug-in portion 20 is inserted into the through hole of the insulating insert plate 1, the chamfer structure can play a guiding role, facilitating insertion.

[0048] More preferably, the chamfer 22 is provided on both sides of the end edge. The chamfer on both sides forms a smooth transition slope, which can guide the insertion part 20 to quickly align with the through hole 10, reducing jamming caused by alignment deviation. Especially in operating environments such as 10kV equipment switch bays where space is limited and visibility is restricted, it can reduce the difficulty of alignment during insertion, allowing operators to complete the insertion smoothly without precise alignment, greatly improving installation efficiency. In addition, the chamfer can eliminate sharp edges, avoiding scratches to personnel during operation, and at the same time preventing damage to the insulation layer or contact box surface of the equipment during insertion, protecting the integrity of the original structure of the equipment, and indirectly improving the safety factor during operation.

[0049] Furthermore, in some specific embodiments, the width of the engaging portion 21 is smaller than the width of the insulating insert 1. This smaller width prevents the engaging portion 21 from extending beyond the edge of the insulating insert 1 during installation or use, and also improves the overall aesthetics of the assembly.

[0050] Furthermore, in some specific embodiments, anti-slip textures 23 are provided on both walls of the insertion portion 20. The anti-slip textures 23 increase the friction between the hand and the walls of the insertion portion 20, preventing slippage when inserting or removing the insulating clip 2 or adjusting the component position. This ensures stable force application by the operator and reduces operational errors caused by hand slippage, making it particularly suitable for situations where hands are sweaty or when wearing insulating gloves. It should be noted that the specific structure of the anti-slip textures 23 is not limited in this invention and can be designed and selected by those skilled in the art based on actual conditions.

[0051] In this embodiment, the method for manufacturing the insulating card plate 2 is as follows:

[0052] A rectangular insulating board with a length of 12cm and a width of 13cm can be selected and cut to form a rectangular engaging portion 21. The engaging portion 21 has dimensions of 12cm in length and 1cm in width. Next, the plug-in portion 20 is cut into a rectangle with a length of 7cm and a width of 12cm. Finally, a chamfer 22 is cut to form a trapezoidal structure at the end of the plug-in portion 20 away from the engaging portion 21. The trapezoid has dimensions of 3.5cm for the short side, 7cm for the long side, and 3cm for the height. This completes the fabrication of the insulating card 2. The structure is simple and easy to manufacture.

[0053] Furthermore, in some specific embodiments, the insulating insert 1 and the insulating clip 2 are made of glass fiber reinforced epoxy resin. Glass fiber reinforced epoxy resin itself has extremely high insulation resistance, and after testing with a 2500V megohmmeter, it stably meets the insulation requirements of 10kV equipment, effectively blocking the current path between the live conductor and the operator, eliminating the risk of electric shock at the material level. It has excellent arc resistance and corona resistance, and can resist instantaneous electric field interference during high-voltage equipment testing, avoiding safety accidents caused by material insulation failure. At the same time, compared with traditional metals or other insulating materials, glass fiber reinforced epoxy resin has a lower density, making the overall weight of the insulating insert and insulating clip lighter. Moreover, it has good processing performance, and can be precisely manufactured into rectangular plate-shaped and strip-shaped through holes, as well as the insertion part 20 and the locking part 21, through conventional processes such as cutting and drilling, ensuring the dimensional accuracy and structural adaptability of the components.

[0054] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
