Description

Technical Field

[0001] The present invention relates to the technical field of monitoring equipment, and in particular to a partial discharge monitoring device with multiple monitoring functions. Background Art

[0002] Partial discharge monitoring equipment is a high-precision electronic device used to detect partial discharge (PD) in the insulation systems of power equipment (such as transformers, cables, and GIS). Essentially, it's an intelligent diagnostic system that integrates multiple sensors. It non-invasively captures, analyzes, and evaluates partial discharge (PD) signals in real time to prevent equipment failures caused by insulation degradation. Partial discharge (PD) is an early sign of insulation degradation in power equipment (such as transformers, GIS, and cables), potentially leading to equipment breakdown or even grid failure. PD monitoring, which assesses equipment health through real-time detection of discharge signals, is a core technology for condition-based maintenance (CMS) in smart grids.

[0003] During use, the rigid structural design of the partial discharge monitoring equipment prevents the sensors in the device from conforming to curved surfaces, resulting in low coupling efficiency, incomplete signal acquisition, and decreased sensitivity. In addition, existing partial discharge monitoring equipment can only adapt to the surfaces of objects of the same type and cannot take into account other types of objects, making the device less applicable. For example, a rectangular partial discharge monitoring device on a box cannot be applied to a tubular object, and a ring-shaped partial discharge monitoring device on a tubular object cannot be applied to a box. Summary of the Invention

Installed on a tubular object, during the rotation of disc one and disc two, due to the action of the limiting block two in the inner cavity of the positioning groove one and the limiting groove block in the inner cavity of the positioning groove two, the two monitoring components one move toward the side of the movable part while the inner cavity of the slide groove moves; due to the action of the limiting block one in the inner cavity of the positioning groove one, the two monitoring components two move toward the side away from the movable part while the inner cavity of the slide groove moves, so that the two monitoring components one and the two monitoring components two can adapt to the curved surface of the tubular object, thereby improving the coupling efficiency of the monitoring components one and two and the curved surface, thereby improving the sensitivity of monitoring.

This device is equipped with a rotatable T-shaped plate and a fixed component, so that the T-shaped plate can be installed on tubular objects of different diameters through the fixed component during the rotation process, thereby improving the applicability of the device; the initial adsorption force provided by the NdFeB magnet sheet is adsorbed on the tubular object, and then adsorbed on the surface of the tubular object through the suction cup.

[0026] 3. Through the cooperation between the monitoring components, movable components and T-shaped plates, the device can change the positions of monitoring component one and monitoring component two when the device is installed on the surface of different types of objects, so that monitoring component one and monitoring component two shrink to form focused monitoring. At the same time, monitoring component one and monitoring component two move, so that monitoring component one and monitoring component two fit the curved surface better to form an adaptive structure. During the rotation of the mounting plate, the connecting rod fixedly connected to the mounting plate rotates with disk one and disk two, so that monitoring component one and monitoring component two move in the inner cavity of the slide toward the center of the fixed block, so that monitoring component one and monitoring component two shrink toward the center of the fixed block, thereby reducing the monitoring range of monitoring component one and monitoring component two, so that monitoring component one and monitoring component two can face the center of the tubular object, so that the two monitoring components one move toward the side of the movable component while moving in the inner cavity of the slide, and the two monitoring components two move toward the side away from the movable component while moving in the inner cavity of the slide, so that monitoring component one and monitoring component two adapt to the tubular object, thereby improving the accuracy of monitoring.

[0049] The following, combined with the accompanying drawings, provides a clear and complete description of the technology in the embodiments of the present invention, a partial discharge monitoring device with multiple monitoring functions. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0050] Example 1: Figure 1-Figure 4 As shown, a partial discharge monitoring device with multiple monitoring functions includes a protective box 10, with an arc-shaped shell 11 in communication with the inner cavity of the protective box 10 fixed on both sides. Two symmetrical T-shaped plates 12 are rotatably installed in the inner cavity of the protective box 10. The T-shaped plates 12 are adapted to the arc-shaped shell 11. The length of the horizontal portion of the T-shaped plate 12 located in the inner cavity of the protective box 10 is the same as the length of the vertical portion of the T-shaped plate 12, and the length of the vertical portion of the T-shaped plate 12 is the same as the radius of the inner surface of the arc-shaped shell 11. When the T-shaped plate 12 is rotated 90 degrees, the arc-shaped shell 11 can still be sealed, thereby preventing impurities and dust from entering the inner cavity of the protective box 10.

[0051] Then, if Figure 5 As shown, the two T-shaped plates 12 have mounting grooves 13 on the sides of their horizontal portions that are away from each other. A clamping column 14 is fixed in the inner cavity of the mounting groove 13. The rotation center of the clamping column 14 is the rotation center of the T-shaped plate 12. The rotation axis of the T-shaped plate 12 is located at the intersection of its vertical portion and horizontal portion, so that the length of the vertical portion of the T-shaped plate 12 is the same as the length of the horizontal portion on the side where the clamping column 14 is located.

[0052] Among them, a control processing component 15 is fixed to the side wall of the inner cavity of the protective box 10. The control processing component 15 includes a control component, a signal processing component and a power supply, etc., which are used to transmit signals and control the use of sensors, all of which are existing technologies;

[0053] Then, if Figure 3 As shown, the horizontal parts of the two T-shaped plates 12 are each provided with a fixing component 20, and the fixing component 20 is fixed to the side of the horizontal part of the T-shaped plate 12 away from the protective box 10. The fixing component 20 is used to fix the device on the surface of the monitored object. It can be a box or a tube, and can adapt to the surface of complex objects. Two symmetrical movable components 30 are fixed in the inner cavity of the protective box 10. The movable component 30 is the middle matching transmission component. A monitoring component 40 adapted to the movable component 30 is fixed on one side of the protective box 10. The monitoring component 40 includes a sensor for monitoring, and the position of the sensor can adapt to complex surfaces.

[0054] Further, if Figure 6As shown, the movable component 30 includes two arc-shaped slot blocks 31 fixed to the top and bottom walls of the inner cavity of the protective box 10. The two arc-shaped slot blocks 31 are respectively fixed to the top and bottom walls of the inner cavity of the protective box 10 and are located on the same vertical line. A connecting shaft 32 slides together in the inner cavities of the two arc-shaped slot blocks 31. A movable plate 33 is fixed to the outer surface of the connecting shaft 32. A slot 34 that cooperates with the clamping column 14 is provided on one side of the movable plate 33. The clamping column 14 can enter the inner cavity of the slot 34. By rotating the T-shaped plate 12, the clamping column 14 enters the inner cavity of the slot 34, so that the connecting shaft 32 slides with the movable plate 33 along the inner cavity of the arc-shaped slot block 31.

[0055] Next, a fixed column 36 is fixed to one side of the movable plate 33, and a rotating plate 35 is movably mounted on the surface of the fixed column 36. During the movement of the movable plate 33, the fixed column 36 moves toward the fixed component 20 and away from the monitoring component 40 at the same time, so that the fixed column 36 and the rotating plate 35 change from being tilted to being vertical, and the rotating plate 35 slides on the fixed column 36.

[0056] In addition, the fixed columns 36 on the two movable plates 33 are installed at different positions to adapt to the components on the monitoring component 40, so that the rotating plates 35 on the two fixed columns 36 are installed one above the other. When the two movable plates 33 move, the two rotating plates 35 rotate with the monitoring component 40.

[0057] Among them, such as Figure 7 As shown, the center of the opening position of the slot 34 is on the same line as the center of the rotation axis of the T-shaped plate 12, and the rotation center of the clamping column 14 is on the same line as the center of the rotation axis of the T-shaped plate 12, so that during the rotation of the T-shaped plate 12, the clamping column 14 can enter the inner cavity of the slot 34, thereby moving with the movable plate 33.

[0058] Further, if Figures 8-10 As shown, the monitoring component 40 includes a fixed frame 48 fixed to the protective box 10. The fixed frame 48 is used to protect the internal sensor. A corrugated plate 49 is fixedly installed on one side of the fixed frame 48. The corrugated plate 49 is made of a flexible material. Firstly, it can buffer the impact generated when the device is adsorbed on the surface of the box. Secondly, it can increase the surface area of ​​the device installed on the tubular object and fit the surface of the monitoring target.

[0059] Among them, a fixed block 44 is fixed to the inner cavity of the fixed frame 48, and four annular array slide grooves 441 are opened on the fixed block 44. The inner cavities of the four slide grooves 441 are respectively provided with a group of monitoring components 1 45 and a group of monitoring components 2 47. The monitoring component 1 45 is in the vertical direction, and the monitoring component 2 47 is in the horizontal direction. The monitoring component 1 45 and the monitoring component 2 47 include a sensor body, a movable column and a connecting column. The movable column is located in the inner cavity of the slide groove 441 and slides. The connecting column is fixed on the movable column for installing the sensor body. A spring is fixed on the movable column of the monitoring component 2 47 for resetting the compressed monitoring component 2 47. The sensors on the monitoring component 1 45 and the monitoring component 2 47 have different functions, so that the device has multiple monitoring functions. The monitoring component 1 45 and the monitoring component 2 47 are distributed perpendicular to each other.

[0060] Next, the monitoring component 40 also includes a mounting plate 41 connected to the rotating plate 35. Two sides of the mounting plate 41 are rotatably connected to a rotating plate 35. The two rotating plates 35 are respectively located on the upper and lower sides of the mounting plate 41. A connecting rod 42 is fixed to one side of the mounting plate 41. The connecting rod 42 rotates through the protective box 10 and is connected to the protective box 10 through a torsion spring. Under the action of the torsion spring, the mounting plate 41 is in a vertical state under normal conditions. A disk 1 43 and a disk 2 46 are fixed to the outer surface of the connecting rod 42. The disk 1 43 and the disk 2 46 cooperate with the monitoring component 1 45 and the monitoring component 2 47 to control the expansion and contraction of the monitoring component 1 45 and the monitoring component 2 47, and at the same time move the monitoring component 1 45 and the monitoring component 2 47.

[0061] Among them, such as Figure 11 As shown, four second latching grooves 461 are formed on one side of the second disk 46. The four second latching grooves 461 correspond to the two first monitoring components 45 and the two second disks 46, respectively. Two of the second latching grooves 461 have fixed inner cavities containing limit blocks 462 that match the first monitoring components 45. The limit blocks 462 are fixed inner cavities of the two second latching grooves 461 in the two vertical directions. The thickness of the limit blocks 462 gradually decreases from the side closest to the center of the circle outward, so that the first monitoring component 45 gradually moves toward the movable component 30 during the rotation of the second disk 46.

[0062] Next, four positioning grooves 1 431 are opened on one side of the disk 1 43, and the four positioning grooves 1 431 correspond to the two monitoring components 1 45 and the two disks 2 46 respectively. The inner cavities of the two positioning grooves 1 431 are fixed with limit blocks 1 432 adapted to the monitoring component 2 47, and the thickness of the limit block 1 432 gradually becomes thinner from the side close to the center of the circle to the outside, and the corresponding inner cavity of the positioning groove 2 461 is flat, so that during the rotation of the disk 1 43, the monitoring component 2 47 moves to the side away from the movable part 30, so that the spring on the monitoring component 2 47 is compressed, and the inner cavities of the other two positioning grooves 1 431 are fixed with limit blocks 2 433 adapted to the monitoring component 1 45, and the thickness of the limit block 2 433 gradually becomes thicker from the side close to the center of the circle to the outside, just corresponding to the limit groove block 462, so that the monitoring component 1 45 moves toward the side of the movable part 30 during the contraction process;

[0063] Through the action of the rotating plate 35, the mounting plate 41 rotates with the connecting rod 42. At the same time, the disc 1 43 and the disc 2 46 rotate, so that the two monitoring components 2 47 move away from the movable part 30, and the two monitoring components 1 45 move toward the movable part 30, so that the two monitoring components 1 45 and the two monitoring components 2 47 can adaptively fit the tubular surface.

[0064] Embodiment 2: This embodiment further defines the fixing component 20 on the basis of embodiment 1, so as to achieve the purpose of making the device applicable to different complex surfaces.

[0065] Specifically, such as Figure 12 and Figure 13 As shown, the fixing component 20 includes two support plates 21, which are respectively fixed to both sides of the horizontal portion of the T-shaped plate 12. An arc block 22 is rotatably mounted between the two support plates 21 via a torsion spring, so that the arc block 22 has a certain amount of movable space, which can better fit the surface of the tubular target. Two groups of NdFeB magnet pieces 23 are provided through grooves provided on the inner surface of the arc block 22. Grooves are provided on both sides of the inner surface of the arc block 22. The inner cavity of the groove is rotatably connected to the NdFeB magnet piece 23 via a torsion spring. The NdFeB magnet piece 23 can be adsorbed on the surface of the switch cabinet and is suitable for the target of the box.

[0066] Next, the fixing component 20 also includes a connecting box 24 fixed on the T-shaped plate 12. A transmission pipeline is installed in the inner cavity of the connecting box 24. A micro air pump 25 is fixed on one side of the connecting box 24. The output end of the micro air pump 25 is connected to the transmission pipeline in the connecting box 24. A plurality of suction cups 26 are fixed on the inner surface of the arc block 22. The connecting box 24 and the plurality of suction cups 26 are connected by an air pipe. The suction cups 26 are connected to the transmission pipeline in the connecting box 24 through the air pipe, so that the suction cups 26 can be adsorbed on the pipeline or on the surface of the box.

[0067] It should be noted that the NdFeB magnet sheet 23, micro air pump 25, suction cup 26 and wave sheet 49 in the present invention are all prior art, and their installation and control methods are also conventional designs, which will not be elaborated in detail in the present invention.

[0068] Working Principle of the Present Invention: This device is a partial discharge monitoring device with multiple monitoring functions. Through the coordination between the T-shaped plate 12, the fixed component 20, the movable component 30, and the monitoring component 40, the device can be installed on the surface of a box or a tubular object, improving the device's applicability. Furthermore, the monitoring component 40 enables the sensors on the monitoring component 1 45 and the monitoring component 2 47 to conform to the curved surface, improving coupling efficiency, thereby achieving complete signal acquisition and increasing sensitivity.

[0069] The device is mounted on the box, and the NdFeB magnets 23 provided on the inner surfaces of the two arc-shaped blocks 22 are adsorbed on the surface of the box to provide initial adsorption force. Then, by activating the micro air pump 25, the suction cups 26 on the inner surfaces of the arc-shaped blocks 22 are adsorbed on the surface of the box to mount the device on the box. At the same time, since the wave sheet 49 is wavy in shape, the wave sheet 49 can extend during the squeezing process, so that the sensors on the monitoring component 1 45 and the monitoring component 2 47 are attached to the wave sheet 49 and fit into the box, thereby improving the coupling efficiency of the device.

[0070] The device is mounted on a tubular object. By rotating the two T-shaped plates 12, the two arc-shaped blocks 22 move toward the surface of the tubular object. The NdFeB magnets 23 on the inner surfaces of the arc-shaped blocks 22 provide an initial adsorption force, allowing the device to be adsorbed on the surface of the tubular object. The suction cups 26 are then used to adsorb on the surface of the tubular object, allowing the device to be mounted on the tubular object. During the rotation of the T-shaped plates 12, the fixing components 20 allow the device to be mounted on tubular objects of different diameters, thereby improving the applicability of the device.

[0071] like Figure 14 and Figure 15 As shown, during the rotation of the T-shaped plate 12, the clamping column 14 on the T-shaped plate 12 engages with the clamping groove 34 on the same side, so that the movable plate 33 slides with the connecting shaft 32 in the inner cavity of the arc-shaped groove block 31. At the same time, the rotating plate 35 rotates along with the movement of the fixed column 36, so that the rotating plate 35 rotates to a horizontal state, and finally the mounting plate 41 rotates from a vertical state to a horizontal state.

[0072] During the rotation of the mounting plate 41, the connecting rod 42 fixedly connected to the mounting plate 41 rotates with the disc 1 43 and the disc 2 46, thereby causing the monitoring component 1 45 and the monitoring component 2 47 to move in the inner cavity of the chute 441 toward the center of the fixed block 44, causing the monitoring component 1 45 and the monitoring component 2 47 to shrink toward the center of the fixed block 44, thereby reducing the monitoring range of the monitoring component 1 45 and the monitoring component 2 47, allowing the monitoring component 1 45 and the monitoring component 2 47 to align with the center of the tubular object, adapt to the tubular object, and improve the accuracy of monitoring;

[0073] In addition, if Figure 16 and Figure 17 As shown, during the rotation of disk 1 43 and disk 2 46, due to the action of the limiting block 2 433 in the inner cavity of the positioning groove 1 431 and the limiting groove block 462 in the inner cavity of the positioning groove 2 461, the two monitoring components 1 45 move toward the side of the movable part 30 while moving in the inner cavity of the slide groove 441. Due to the action of the limiting block 1 432 in the inner cavity of the positioning groove 1 431, the two monitoring components 2 47 move toward the side away from the movable part 30 while moving in the inner cavity of the slide groove 441, so that the two monitoring components 1 45 and the two monitoring components 2 47 can adapt to the curved surface of the tubular object, thereby improving the coupling efficiency between the monitoring components 1 45 and the monitoring components 2 47 and the curved surface, thereby improving the monitoring sensitivity.

[0074] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art, within the technical scope disclosed by the present invention, who can make equivalent replacements or changes to a partial discharge monitoring device with multiple monitoring functions and its inventive concept according to the technology of the present invention, should be covered by the scope of protection of the present invention.
