Description

Technical Field

[0001] This utility model relates to the field of discharge detection, and in particular to a partial discharge detection device for photovoltaic power plants. Background Technology

[0002] Currently, with the development of renewable energy, the application of photovoltaic power stations is becoming increasingly widespread in my country. In the operation of photovoltaic power stations, in order to ensure the safe and stable operation of the equipment, partial discharge detection has become an essential part. Partial discharge refers to the phenomenon of breakdown in some areas of the insulation system of electrical equipment. It is one of the important indicators for assessing the insulation status of high-voltage power equipment.

[0003] However, when performing partial discharge detection, it is usually necessary to manually clamp the clamp of the detection device at close range to the target position. Since the electrical equipment in photovoltaic power stations is often in a high voltage state, this poses a risk of electric shock to the operator when performing the detection. Especially when the operating space is narrow and the environment is complex, it is not only difficult to approach the detection point with the clamp by hand, but also increases the safety hazard.

[0004] Therefore, it is necessary to provide a partial discharge detection device for photovoltaic power plants to solve the above-mentioned technical problems. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] This application provides a partial discharge detection device for photovoltaic power plants, which solves the problem in related technologies where, when performing partial discharge detection, it is usually necessary to manually clamp the clamp of the detection device at close range to the target position. Since the electrical equipment in photovoltaic power plants is often in a high voltage state, this poses a risk of electric shock to the operator when performing the detection.

[0028] Please see Figures 1-6 A partial discharge detection device for photovoltaic power plants, comprising:

[0029] Device body 1;

[0030] The remote clamping assembly consists of two sets. Each set includes a retractable sleeve 2, a first spring 3, a connecting line 4, a first control handle 5, a second control handle 6, a sleeve 7, a second spring 9, a clamp 18, and a fourth spring 19. The sleeve 7 is fixedly connected to the surface of the main body 1 of the device. The connecting line 4 is slidably connected to the inner wall of the sleeve 7. The second control handle 6 is fixedly connected to the circumferential surface of the sleeve 7. The first control handle 5 slides on the circumferential surface of the connecting line 4. The second spring 9 is sleeved on the circumferential surface of the connecting line 4, and its upper end is fixedly connected to the surface of the first control handle 5. The first spring 3 is sleeved on the circumferential surface of the connecting line 4, and its lower end is fixedly connected to the surface of the first control handle 5. The retractable sleeve 2 is sleeved on the circumferential surface of the first spring 3, and its lower end is fixedly connected to the upper end of the first spring 3. The clamp 18 is fixedly connected to the upper end of the connecting line 4. Both ends of the fourth spring 19 are fixedly connected to the surface of the clamp 18.

[0031] The disassembly assembly is provided in two sets, and the two sets of disassembly assemblies are respectively installed in the two sleeves 7;

[0032] A storage component is disposed on one side of the main body 1 of the device;

[0033] In this implementation process, the device achieves remote operation through a remote clamping component. During operation, the thumb grips the second control handle 6, while the index and middle fingers simultaneously press the first control handle 5. At this time, the first control handle 5 moves downward against the elastic force of the second spring 9, causing the first spring 3 fixed on its surface to move downward synchronously. The retractable sleeve 2 moves down and releases the constraint of the clamp 18. The fourth spring 19 opens the clamp to the open state, facilitating quick clamping of the target position. After releasing the control handle, the second spring 9 pushes the first control handle 5 back to its original position, and the retractable sleeve 2 moves up to abut against the clamp 18, closing and fixing it. This allows for remote clamping at the target position. The first spring 3 adopts a dense, fine spring design, which ensures that the connecting wire 4 maintains rigidity during lifting while avoiding excessively stiff springs that affect storage flexibility. The remote clamping component enables remote operation, effectively solving the problem of electric shock risk caused by proximity to high-voltage equipment when using traditional handheld clamps for testing.

[0034] The first control handle 5 has anti-slip grooves 15 on its surface, which increase friction and improve operational stability. Under high pressure, the operator can firmly grip the control handle even when wearing insulated gloves, avoiding misoperation due to slipperiness or excessive force, thereby reducing the risk of clamp failure or accidental loosening of the clamp 18 and further ensuring the safety of the testing process.

[0035] Specifically, in this embodiment, each set of disassembly components includes a limiting block 11, a stop plate 12, a limiting groove 13, and a third spring 14. The limiting block 11 is fixedly connected to the surface of the connecting line 4, the limiting groove 13 is opened in the inner wall of the sleeve 7, the lower end of the third spring 14 is fixedly connected to the inner wall of the sleeve 7, the stop plate 12 is fixedly connected to the upper end of the third spring 14, and the limiting block 11 is slidably connected to the inner wall of the limiting groove 13.

[0036] When it is necessary to assemble or disassemble the connecting cable 4, the disassembly assembly achieves quick assembly or disassembly of the connecting cable 4 through the linkage of the limiting block 11, the limiting groove 13, and the third spring 14. During operation, insert the connecting cable 4 into the sleeve 7, manually overcome the elastic force of the third spring 14 to press down on the abutment plate 12, causing the limiting block 11 to slide into the opening position of the J-shaped slot in the limiting groove 13. After rotating the connecting cable 4, release it, and the third spring 14 pushes the abutment plate 12 back to its original position, allowing the limiting block 11 to lock into the limiting groove 13. This design avoids the accidental detachment of traditional direct-insertion connecting cables due to external impact. At the same time, the rotation unlocking method is simple to operate, requires no tools, and significantly improves the maintenance efficiency and on-site adaptability of the equipment.

[0037] Specifically, in this embodiment, the storage component includes a storage box 8, a sealing plate 10, a pusher 16, and a pusher 16. The storage box 8 is fixedly connected to the surface of the device body 1, the sliding groove 17 is formed on the surface of the storage box 8, the sealing plate 10 is slidably connected to the inner wall of the sliding groove 17, and the pusher 16 is fixedly connected to the surface of the sealing plate 10.

[0038] The storage component enables convenient storage of the clip 18 through the cooperation of the sliding sealing plate 10 and the push block 16. The sealing plate 10 slides into the sliding groove 17 of the storage box 8, and the push block 16 serves as an operating handle. The storage box can be opened or closed by sliding the sealing plate 10. The clip 18 can be folded and stored in the box to avoid collision damage during carrying. This design not only saves space, but also prevents the clip from getting damp or accumulating dust through the closed structure, thus extending its service life. At the same time, the sliding operation is simple and suitable for testing scenarios with frequent disassembly and assembly.

[0039] Specifically, in this embodiment, the surface of the main body 1 of the device is fixedly connected with anti-slip texture 20;

[0040] The anti-slip texture 20 on the surface of the main body 1 enhances the fit with the operator's palm through its concave-convex texture design. Especially in the complex environment of outdoor photovoltaic power stations, such as slippery ground and strong winds and sand, it can effectively prevent the equipment from slipping and ensure the stability of the equipment during the testing process. In addition, the anti-slip texture 20 also optimizes the grip of the equipment and reduces fatigue caused by long-term operation.

[0041] Specifically, in this embodiment, both shrink sleeves 2 are made of silicone rubber;

[0042] The shrink sleeve 2 is made of silicone rubber, which has excellent insulation and weather resistance. When clamping high-voltage equipment, it can effectively block current and avoid the risk of electric shock to the operator. The flexibility of silicone rubber makes it less prone to breakage during compression and rebound, and its smooth surface reduces friction loss with the clamp 18, extending its service life. At the same time, its compressibility makes it easy to fold the clamp 18 and store it in the storage box 8, which can meet the testing needs of the narrow space of the photovoltaic power station.

[0043] The working principle of the partial discharge detection device for photovoltaic power plants provided by this utility model is as follows: This device achieves safe detection of high-voltage equipment through a remote clamping component. The operator presses the first control handle 5 and the second control handle 6, and uses the elastic transmission of the spring to remotely open and precisely close the clamp 18, avoiding direct contact with the high-voltage equipment and thus reducing the risk of electric shock. The clamp 18 is opened by the fourth spring 19 and is protected by the insulation of the silicone rubber shrink sleeve 2, ensuring the safety of the clamping process. The disassembly component enhances the stability of the connecting wire 4 and prevents accidental detachment through the rotational locking design of the J-shaped limiting groove 13 and the limiting block 11. The anti-slip texture 20 of the device body 1 and the anti-slip groove 15 of the control handle further improve the operational stability. At the same time, the storage component realizes the folding and storage of the clamp, taking into account both portability and practicality. The overall design, through the combination of mechanical linkage and insulation protection, solves the high-risk problem of close-range detection by traditional handheld clamps 18, and significantly improves the efficiency and safety of partial discharge detection in photovoltaic power plants.
