Description

Technical Field

[0001] This invention relates to the field of power quality monitoring technology, specifically to a power quality monitoring device for ultra-high voltage power transmission. Background Technology

[0002] The ultra-high voltage power quality monitoring device is a device used to monitor the power quality of ultra-high voltage lines. This device is an important piece of equipment to ensure the safe and stable operation of the ultra-high voltage power grid. Its design and implementation need to meet a series of basic requirements and have functions such as real-time monitoring, data analysis, fault early warning and diagnosis.

[0003] Current ultra-high voltage (UHV) power quality monitoring devices are typically installed at the connection points of UHV transmission lines in power plants and substations, i.e., in outdoor equipment areas. In dusty weather, if not cleaned regularly, dust accumulates on the surface of these devices, affecting heat dissipation and ventilation, and even blocking ventilation openings or heat dissipation holes. This blockage leads to the accumulation of dust and dirt inside the equipment, which can cause electrical faults. For example, dust adhering to circuit boards can cause short circuits or poor contact. Furthermore, excessively high temperatures accelerate the aging of internal components, increasing the risk of failure and causing overheating, which in turn affects the operation of mechanical parts and degrades performance.

[0004] Meanwhile, most current ultra-high voltage (UHV) power quality monitoring devices are located in power plants and substations. Due to the large size and weight of these devices, specific tools and equipment are required for installation and dismantling. Strict installation accuracy requirements and system integration must also be considered, making the installation and dismantling of power quality monitoring devices overly complex. In high-voltage environments, any delays or complex installation and dismantling processes increase the risk of electric shock to operators. Furthermore, in substations, the transmission and distribution of electrical energy must maintain continuity and stability. If the installation and dismantling of power quality monitoring devices takes too long, it will interrupt grid monitoring, affecting real-time understanding of grid status and thus adversely impacting the stable operation of the grid.

[0005] Therefore, a power quality monitoring device for ultra-high voltage power transmission was proposed to solve the above problems. Summary of the Invention

[0006] In view of this, the technical problem to be solved by the present invention is to provide a power quality monitoring device for ultra-high voltage power transmission, so as to solve the problems of filter clogging and inability to quickly install and disassemble existing power quality monitoring devices.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a power quality monitoring device for ultra-high voltage power transmission, comprising a carrier plate, wherein the number of carrier plates is set to two, and a monitoring device body is fixedly connected between the two carrier plates.

[0011] Preferably, a rubber ring is fixedly connected to the side of the monitoring device body away from the cooling fan, a rotating bracket is fixedly connected to the end of the drive shaft away from the cooling fan, pushing blocks are evenly fixedly connected to the rotating bracket, a filter plate is fixedly connected to the inner wall of the rubber ring, a support frame is fixedly connected to the side of the filter plate near the rotating bracket, and fixed wheels are evenly fixedly connected to the support frame.

[0012] Preferably, a fixing frame is fixedly connected to the outer surface of the monitoring device body on the side away from the cooling fan, and an auxiliary spring is fixedly connected between the fixing frame and the center of the filter plate.

[0013] Preferably, the convenient installation mechanism includes two locking platforms, which are fixedly connected to the surface of the carrier plate. Each locking platform has a sliding groove inside, and an adjustment platform is slidably connected to the inner wall of the sliding groove. The adjustment platform has an inclined hole. Each locking platform has a pull-out block slidably connected to the inner wall of the two locking platforms. The pull-out block is fixedly connected to the monitoring device body. A locking post is fixedly connected to the side of the pull-out block near the adjustment platform. The locking post is slidably connected to the inclined hole. Each pull-out block has a handrail fixedly connected to the side away from the locking post.

[0014] Preferably, guide rails are symmetrically fixedly connected to the upper surface of the locking platform on the same side, a sliding ring is slidably connected between the two guide rails, a baffle is fixedly connected between the two guide rails, a locking spring is fixedly connected to the side of the baffle near the sliding ring, and the side of the locking spring away from the baffle is fixedly connected to the sliding ring.

[0015] Preferably, guide rails are symmetrically fixedly connected to the upper surface of the pull-out block on the same side, a pressing block is slidably connected between the two guide rails, a snap-fit ​​block is fixedly connected to the inner wall of the sliding ring, and a right-angle rack is fixedly connected to the side of the adjustment table near the spring.

[0016] As a preferred embodiment, a detection method for a power quality monitoring device used in ultra-high voltage power transmission is proposed, characterized in that:

[0017] Step 1: Device Installation and Configuration

[0018] First, install an ultra-high voltage power quality monitoring device and configure it according to actual needs to ensure that the monitoring device can accurately monitor key power quality parameters in the power grid.

[0019] Step Two: Online Real-Time Monitoring

[0020] After the device is installed, online real-time monitoring begins. During this stage, attention is paid to the frequency, voltage, and current parameters of the power grid, as well as existing harmonic and flicker issues.

[0021] Step 3: Data Analysis and Reporting

[0022] The data from online real-time monitoring is collected and analyzed. By analyzing the data, the power quality of the power grid can be assessed, potential problems can be identified, and corresponding improvement measures can be proposed. Finally, a power quality monitoring report is generated based on the analysis results, providing decision support for the operation and maintenance of the power grid.

[0023] Compared with the prior art, the present invention provides a power quality monitoring device for ultra-high voltage power transmission, which has the following beneficial effects:

[0024] 1. By sliding between the fixed wheel and the push block, and with the spring force exerted on the filter screen, the filter screen is continuously shaken. This greatly enhances the self-cleaning ability of the filter screen, effectively preventing the accumulation of dust and other contaminants. Through continuous shaking, the filter screen can shake off the attached dust particles, maintain its ventilation performance, and ensure that the inside of the equipment is not affected by external pollution, thereby maintaining the normal operation and accuracy of the equipment. Secondly, the self-shaking filter screen not only extends the service life of the filter screen itself, but also indirectly improves the durability of the entire equipment. Due to the reduction of dust accumulation, the filter screen is prevented from being easily clogged. In addition, the automatically cleaning filter screen reduces the need for manual intervention, making the maintenance of the equipment simpler and more efficient.

[0025] 2. The filter screen shaking mechanism also plays a key role in improving the heat dissipation efficiency of the equipment. In high-pressure environments, the heat dissipation performance of the equipment is crucial. By preventing dust from clogging the heat dissipation holes and ventilation channels, the self-shaking filter screen ensures the effective dissipation of heat inside the equipment, preventing overheating. Good ventilation and heat dissipation are key to the long-term stable operation of the equipment. The self-shaking filter screen helps reduce the risk of equipment damage due to overheating by maintaining ventilation performance, thereby extending the service life of the equipment.

[0026] 3. Through the insertion between the inclined hole and the snap-fit ​​post, the staff can quickly complete the fixed installation and disassembly of the monitoring device body by pushing the handle. The convenient installation mechanism helps to reduce safety risks. Working in a high-voltage environment is inherently dangerous. If the installation and disassembly process is cumbersome and complicated, it will not only increase the workload of the operators, but also increase the risk of safety accidents such as electric shock. The convenient installation mechanism can reduce the exposure time of the operators in the high-voltage environment, thereby reducing safety risks. In addition, the convenient installation mechanism can respond more flexibly to the changing needs of the power grid, improving the stability of the power grid and the quality of power supply.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0043] Example 1

[0044] Please refer to Figures 2 to 4 As shown:

[0045] To address the problems mentioned in the technical solutions, this application provides a power quality monitoring device for ultra-high voltage power transmission, including a carrier plate 1. The number of carrier plates 1 is set to two, and a monitoring device body 2 is fixedly connected between the two carrier plates 1. A control panel 21 is installed on the monitoring device body 2. The power quality monitoring device for ultra-high voltage power transmission includes a filter screen shaking mechanism and a convenient installation mechanism. The convenient installation mechanism is symmetrically arranged on both sides of the upper end of the monitoring device body 2, and the filter screen shaking mechanism is located below the convenient installation mechanism.

[0046] The filter screen shaking mechanism is used to maintain good ventilation of the filter screen;

[0047] The convenient installation mechanism is designed to facilitate the quick installation and removal of the monitoring device body 2 by staff.

[0048] The filter shaking mechanism includes a cooling fan 301, which is installed on the inner wall of the monitoring device body 2. A support rod 302 is fixedly connected to the inner wall of the monitoring device body 2. A drive shaft 303 is fixedly connected to the output shaft of the external motor of the cooling fan 301. The drive shaft 303 is rotatably connected to the support rod 302. A rotating bracket 304 is fixedly connected to the end of the drive shaft 303 away from the cooling fan 301.

[0049] A rubber ring 305 is fixedly connected to the side of the monitoring device body 2 away from the cooling fan 301. A rotating bracket 304 is fixedly connected to the end of the drive shaft 303 away from the cooling fan 301. Push blocks 306 are evenly fixedly connected to the rotating bracket 304. A filter plate 307 is fixedly connected to the inner wall of the rubber ring 305. A support frame 308 is fixedly connected to the side of the filter plate 307 near the rotating bracket 304. Fixed wheels 311 are evenly fixedly connected to the support frame 308.

[0050] A mounting bracket 309 is fixedly connected to the outer surface of the monitoring device body 2 on the side away from the cooling fan 301. An auxiliary spring 310 is fixedly connected between the mounting bracket 309 and the center of the filter plate 307.

[0051] Among them: the rubber ring 305 is made of rubber and has tear resistance and electrical insulation, as well as wear resistance and drought resistance. One side of the push block 306 is an inclined surface. During the process of the fixed wheel 311 sliding from the lower end of the inclined surface of the push block 306 to the upper end of the inclined surface, the fixed wheel 311 pushes the filter plate 307 to move away from the rotating bracket 304.

[0052] In existing technologies, the filters in power quality monitoring devices do not have a self-shaking function. Dust in the air can clog the device's ventilation openings or heat dissipation holes, leading to the accumulation of dust and dirt inside the device. These contaminants can cause electrical faults. In addition, excessively high temperatures accelerate the aging of internal components, increasing the risk of failure and causing the device to overheat, which in turn affects the operation of mechanical parts and reduces performance. Compared with existing technologies, the implementation of this embodiment, through the filter shaking mechanism, continuously shakes the filter plate 307 to shake off attached dust particles, maintain its ventilation performance, ensure that the device is not affected by external pollution, reduce dust accumulation, prevent the filter plate 307 from clogging easily, and prevent overheating. This not only maintains the stable operation of the device but also improves its overall performance.

[0053] Further examples: Please refer to Figures 5 to 8 As shown:

[0054] The convenient installation mechanism includes two locking platforms 401, which are fixedly connected to the surface of the carrier plate 1. Each locking platform 401 has a sliding groove inside, and an adjustment platform 402 is slidably connected to the inner wall of the sliding groove. An inclined hole 405 is provided on the adjustment platform 402. Each locking platform 401 has a pull block 403 slidably connected to the inner wall of the two locking platforms 401. The pull block 403 is fixedly connected to the monitoring device body 2. A locking post 404 is fixedly connected to the side of the pull block 403 closest to the adjustment platform 402. The locking post 404 is slidably connected to the inclined hole 405. Each pull block 403 has a handrail 413 fixedly connected to the side away from the locking post 404.

[0055] On the same side of the snap-fit ​​platform 401, guide rails 406 are symmetrically fixedly connected to the upper surface. A sliding ring 408 is slidably connected between the two guide rails 406. A baffle 407 is fixedly connected between the two guide rails 406. A snap-fit ​​spring 409 is fixedly connected to the side of the baffle 407 near the sliding ring 408. The side of the snap-fit ​​spring 409 away from the baffle 407 is fixedly connected to the sliding ring 408.

[0056] Guide rails 414 are symmetrically fixedly connected to the upper surface of the pull-out block 403 on the same side. A pressing block 410 is slidably connected between the two guide rails 414. A snap-fit ​​block 412 is fixedly connected to the inner wall of the sliding ring 408. A right-angle rack 411 is fixedly connected to the side of the adjustment table 402 near the spring 409.

[0057] Wherein: the height of the upper and lower ends of the inner wall of the locking platform 401 is adapted to the height of the pull block 403, the inclined surface of the right angle rack 411 is adapted to the inclined surface of the locking block 412, the right angle rack 411 and the locking block 412 are locked together, the inclined hole 405 is inclined, the inclined hole 405 can convert the lateral force of the locking post 404 into the longitudinal force, and the inclined hole 405 moves upward during the process of the locking post 404 entering the inclined hole 405.

[0058] In the prior art, due to the high-voltage environment, the installation or dismantling of the monitoring device body 2 is time-consuming. Moreover, in substations, the transmission and distribution of electrical energy must maintain continuity and stability. If the installation and dismantling process of the monitoring device body 2 takes too long, it will interrupt the monitoring of the power grid, affecting the real-time grasp of the power grid status, and thus adversely affecting the stable operation of the power grid. Compared with the prior art, the implementation of this embodiment can reduce the exposure time of operators in the high-voltage environment through the convenient installation mechanism, thereby reducing safety risks. In addition, the convenient installation mechanism can more flexibly respond to the changing needs of the power grid, improving the stability of the power grid and the quality of power supply.

[0059] Example 2

[0060] Step 1: Device Installation and Configuration

[0061] First, install an ultra-high voltage power quality monitoring device and configure it according to actual needs to ensure that the monitoring device body 2 can accurately monitor key power quality parameters in the power grid.

[0062] Step Two: Online Real-Time Monitoring

[0063] After the device is installed, online real-time monitoring begins. During this stage, attention is paid to the frequency, voltage, and current parameters of the power grid, as well as existing harmonics and flicker issues.

[0064] Step 3: Data Analysis and Reporting

[0065] The data from online real-time monitoring is collected and analyzed. By analyzing the data, the power quality of the power grid can be assessed, potential problems can be identified, and corresponding improvement measures can be proposed. Finally, a power quality monitoring report is generated based on the analysis results, providing decision support for the operation and maintenance of the power grid.

[0066] The working principle of all the content in the above embodiments is as follows:

[0067] In the initial state: the fixed wheel 311 intersects the inclined surface of the push block 306 at the end away from the rotating bracket 304, the auxiliary spring 310 is in an elastic contraction state, the adjustment table 402 and the pull block 403 are close to each other, and the operator holds the handle 413 with his thumb in contact with the pressing block 410.

[0068] The following describes the working process of the filter screen shaking mechanism continuously shaking the filter screen plate 307:

[0069] When the power quality monitoring device is monitoring the voltage, current, frequency, etc. of the power grid in real time, the cooling fan 301 rotates to cool the power quality monitoring device. The transmission shaft 303, which is fixedly connected to the output shaft of the external motor of the cooling fan 301, drives the rotating bracket 304 to rotate. Since the fixed wheel 311 is initially located on the inclined surface of the push block 306 away from the rotating bracket 304, the filter plate 307 is in a compressed state relative to the auxiliary spring 310. When the fixed wheel 311 moves away from the push block 306 away from the rotating bracket 304... After the end surface slides, the elastic force of the auxiliary spring 310 will push the filter plate 307 towards the rotating bracket 304. Then, the fixed wheel 311 will slide with the rotating bracket 304, and the rotating bracket 304 will continue to rotate with the cooling fan 301. Subsequently, as the fixed wheel 311 slides from the end of the inclined surface of the push block 306 near the rotating bracket 304 to the end away from the rotating bracket 304, since one side of the push block 306 is an inclined surface, there is a height difference between the push block 306 and the rotating bracket 304. Therefore, the fixed wheel 311 pushes the filter plate 307 to move away from the rotating bracket 304. At this time, the auxiliary spring 310 is elastically compressed by the movement of the filter plate 307. When the rotating bracket 304 rotates to the point where the pushing block 306 does not coincide with the relative position of the fixed wheel 311, the fixed wheel 311 moves towards the rotating bracket 304 under the elastic extension of the auxiliary spring 310. This process repeats itself. At the same time, since the monitoring device body 2 and the filter plate 307 are fixedly connected by a rubber ring 305, the filter plate 307 will reciprocate under the action of the rubber material of the rubber ring 305. That is, the filter plate 307 can shake off the attached dust particles, reduce the accumulation of dust, avoid the filter plate 307 from being easily blocked, and maintain its ventilation performance, ensuring that the inside of the equipment is not affected by external pollution, thereby maintaining the normal operation and accuracy of the equipment. At the same time, the self-shaking filter plate 307 ensures the effective dissipation of heat inside the equipment and prevents overheating problems, which plays a key role in high-pressure environments.

[0070] Please refer to the above work process. Figures 2 to 4 .

[0071] The following is a description of the disassembly and installation process of the monitoring device body 2 using the convenient installation mechanism:

[0072] When disassembling the monitoring device body 2, the operator needs to hold the handle 413 while pressing the pressing block 410 with their thumb. This causes the pressing block 410 to push the sliding ring 408, which slides away from the locking spring 409 in the guide rail 406. At this time, the locking spring 409, which is fixedly connected to the sliding ring 408, is compressed, and the locking block 412, which is fixedly connected to the sliding ring 408, slides away from the pressing block 410 until the locking block 412 is released from the locking state with the right-angle rack 411. Then, while pressing the pressing block 410 with their thumb, the operator holds and pulls the handle 413 away from the adjustment platform 402. This releases the locking state between the right-angle rack 411 and the locking block 412. This causes the locking post 404, which is fixedly connected to the pull block 403, to move away from the adjustment platform 402. At the same time, the locking post 404 and the tilting hole 405 are tilted. The locking post 404 pushes the adjustment platform 402 with the help of the tilting hole 405. This causes the adjustment platform 402 to slide down in the groove of the locking platform 401 until the locking post 404 is pulled out from the tilting hole 405. The lower surface of the adjustment platform 402 contacts the lower surface of the inner wall of the locking platform 401. The tilting hole 405 releases the fixing of the locking post 404. Since the pull block 403 is fixedly connected to the monitoring device body 2, the release of the locking post 404 by the tilting hole 405 means the release of the fixing of the monitoring device body 2, that is, the disassembly of the monitoring device body 2 is completed.

[0073] Furthermore, when the staff needs to install the monitoring device body 2, the adjustment platform 402 is in contact with the bottom of the inner wall of the locking platform 401. The staff only needs to hold and push the handle 413 towards the locking platform 401. The end of the locking post 404 away from the pull block 403 will enter the inclined hole 405. As the locking post 404 continues to enter the inclined hole 405, the inclined surface will convert the lateral force into the longitudinal force, that is, the adjustment platform 402 will move upward. The inclined surface of the right-angle rack 411 fixedly connected to the adjustment platform 402 will first fit against the inclined surface of the locking block 412. As the platform 402 continues to rise, the right-angle rack 411 also rises. The interaction between the right-angle rack 411 and the inclined surface of the locking block 412 causes the rack 411 to push the locking block 412. The sliding ring 408, fixedly connected to the locking block 412, moves away from the pressing block 410, compressing the locking spring 409 until it returns to its initial state, where the surfaces of the adjusting platform 402 and the pull-out block 403 are in contact. The locking block 412 and the right-angle rack 411 continue to be locked, thus fixing the adjusting platform 402 and preventing it from moving up or down. At this time, the locking post 404 is located in the inclined hole. In part 405, due to the inclined surface, the inclined hole 405 restricts the lateral movement of the pull-out block 403. The height of the upper and lower ends of the inner wall of the locking platform 401 is matched with the height of the pull-out block 403, thus allowing the pull-out block 403 to be fixed, which in turn fixes the monitoring device body 2. Therefore, in summary, the operator only needs to hold the handle 413 while pressing the pressing block 410 with their thumb, pulling the handle 413 away from the locking platform 401 to separate the pull-out block 403 from the locking platform 401, enabling disassembly. Alternatively, the operator can hold the handle 413 and push it towards the locking platform 401 to pull out the pull-out block 403. Installation is completed when block 403 overlaps with the card slot 401. The convenient installation mechanism allows for quick installation and disassembly of the monitoring device body 2. This mechanism helps reduce safety risks, as working in a high-voltage environment inherently carries certain dangers. If the installation and disassembly process is cumbersome and complex, it will not only increase the workload of operators but also increase the risk of electric shock and other safety accidents. The convenient installation mechanism can reduce the exposure time of operators in a high-voltage environment, thereby reducing safety risks. In addition, the convenient installation mechanism can more flexibly respond to changes in the power grid, improving the stability of the power grid and the quality of power supply.
