Description

Technical Field

[0001] The present invention relates to the technical field of transformer safety protection, and in particular to an equipment intelligent operation analysis method and device based on a power generation operation management system. Background Art

[0002] Traditional shift handover management at thermal power plants remains largely handwritten and oral, resulting in low efficiency and prone to omissions. Shift handovers require the transmission of production information, which must be manually collected and recorded. This prevents automated integration of shift handover management information, leaving no trace at each point in the handover process, making it difficult to trace. There is no standardized process management to regulate the entire shift handover process, and there is no effective real-time monitoring method. Therefore, a search revealed a patent (Announcement No.: CN114007001B) that discloses a method and apparatus for monitoring equipment operation based on a power generation operation management system. The patent document describes a method for installing and removing a camera using a suction cup and an air intake structure provided on the cup, replacing traditional bolt-on methods. This makes camera installation and removal more convenient, reduces the workload of personnel, and allows for quick repair and replacement of damaged cameras, enabling more effective monitoring of equipment within the power generation operation management system.

[0003] While the aforementioned solution allows monitoring of equipment within the power generation operation and management system through monitoring devices, it lacks effective safety protection in the event of equipment failure. In actual power generation operation and management systems, the main display terminal is located near the monitoring system operator station, with terminal extensions configured at the plant and substation for synchronous display, facilitating operator monitoring and maintenance personnel's equipment analysis. The system's various screens should be highly integrated, displaying current alarm information in real time with audible alarms. Data acquisition devices monitor equipment operating data, allowing monitoring personnel to quickly access fault information upon an equipment failure alarm.

[0004] In the power generation operation and management system, even if the substation transformer monitors the equipment working data through the data acquisition device, the temperature change and the operation of the power can easily cause a fire. The transformer is in the air, and the fire extinguisher cannot block the combustion-supporting substance (oxygen) when extinguishing the fire, resulting in poor transformer fire extinguishing effect and insufficient safety performance.

[0005] In view of this, the present invention proposes an equipment intelligent operation analysis method and device based on a power generation operation management system. Summary of the Invention

[0023] Preferably, it is characterized in that the first through groove and the second through groove are staggered in the vertical and horizontal directions, and filter screens are fixedly connected inside the first through groove and the second through groove.

[0024] The equipment intelligent operation analysis method based on the power generation operation management system includes the following steps:

[0025] S1. Initially, the second offset pipe and the central axis of the first offset pipe coincide with each other, and the arc-shaped cover completely blocks and seals the spray micropores on its upper side. Then, the power is turned on, and the motor is started. The motor drives the impeller (not shown) inside the housing to rotate through its output shaft. Under the action of centrifugal force, the high-speed rotating impeller sucks the cooling water inside the cooling water tank through the water inlet end and discharges it into the water inlet pipe through the water outlet end. The cooling water is then transported to the winding pipe through the water inlet pipe, and heat is exchanged between the winding pipe and the outer wall of the transformer. The heat-exchanged water is then discharged into the spray mechanism through the drain pipe.

[0026] S2. The water discharged from the drainage pipe enters the Z-shaped water pipe, flows into the second staggered delivery pipe through the Z-shaped water pipe, and the second staggered delivery pipe flows into the first staggered pipe through the connecting hole, and finally returns to the cooling water tank, forming a cycle to achieve water cooling for the transformer;

[0027] S3. When the suction and drainage component is working, the first bevel gear and the second bevel gear are used to drive the second pulley located on the lower side to rotate. Under the action of the second transmission belt, the two second pulleys rotate synchronously. The second pulley drives the sleeve to rotate through the star shaft, and the sleeve drives the first gear to rotate through the second gear. The first gear drives the fan to rotate under the action of the first transmission belt and the two first pulleys, thereby sucking air from the inside of the protective frame to achieve air cooling for the transformer. In addition, since the first through slot and the second through slot are staggered in the vertical and horizontal directions, while achieving ventilation, it is very good to prevent external dust and water vapor from entering the interior of the protective frame.

[0028] S4. When a fire occurs in the transformer, the smoke sensor detects smoke and controls the electric telescopic rod to retract, causing the electric telescopic rod to pull the cross-section plate through the connecting block, so that the cross-section plate passes through the cavity and is inserted into the overlap groove. With the cooperation of the spherical sealing gasket, the cross-section plate partitions the cavity, achieving isolation between the inside and outside of the protective frame, preventing oxygen from continuously entering the protective frame and causing a larger fire;

[0029] S5. In addition, after the cross-plate is inserted into the overlapping groove, the first offset pipe and the second offset delivery pipe are offset, the lower port of the second offset delivery pipe is blocked by the cross-plate, and the first gear and the second gear are offset and no longer meshed. Therefore, in the process of the suction and drainage component transporting the cooling water inside the cooling water tank to the inside of the winding pipe, the ventilation component stops working, and the movement of the cross-plate will drive the right-angle rod to move, and the right-angle rod pulls the arc cover plate through the connecting column, so that the arc cover plate and the spray micropore are offset. Since the lower port of the second offset delivery pipe is blocked by the cross-plate, more and more water enters the Z-shaped water pipe, and the water pressure gradually increases. The water accumulated inside the Z-shaped water pipe will be ejected through the spray micropores, and the fire is extinguished by water spray.

[0030] The working principle and beneficial effects of the present invention are:

[0031] In the present invention, when no fire occurs, the second staggered delivery pipe coincides with the central axis of the first staggered pipe, the arc-shaped cover plate completely blocks and seals the spray micropores located on its upper side, the suction and drainage component delivers cooling water to the winding pipe through the water inlet pipe, and the winding pipe is used to exchange heat with the outer wall of the transformer. The water after heat exchange is discharged into the spray mechanism through the drain pipe, and the water discharged from the drain pipe enters the Z-shaped water pipe, flows into the second staggered delivery pipe through the Z-shaped water pipe, and then flows into the first staggered delivery pipe through the connecting hole, and finally returns to the cooling water tank, forming a cycle to achieve water cooling of the transformer;

[0032] In the present invention, when the suction and drainage component is in operation, it also utilizes and drives the second pulley located on the lower side to rotate together with the first bevel gear. Under the action of the second transmission belt, the two second pulleys rotate synchronously. The second pulley drives the sleeve to rotate via the star shaft, and the sleeve drives the first gear to rotate via the second gear. The first gear, under the action of the first transmission belt and the two first pulleys, drives the fan to rotate, sucking air from the interior of the protective frame to achieve air cooling for the transformer and further improve the heat dissipation effect of the transformer. In addition, because the first through-slot and the second through-slot are staggered in the vertical and horizontal directions, while achieving ventilation, it effectively prevents external dust and water vapor from entering the interior of the protective frame.

[0033] In the present invention, when a fire occurs in the transformer, the smoke sensor detects smoke and controls the electric telescopic rod to retract, causing the electric telescopic rod to pull the cross-section plate through the connecting block, so that the cross-section plate passes through the cavity and is inserted into the overlap groove. With the cooperation of the spherical sealing gasket, the cross-section plate partitions the cavity, thereby isolating the inside and outside of the protective frame, preventing oxygen from continuously entering the protective frame and causing a larger fire.

[0034] In the present invention, after the cross-plate is inserted into the lap groove, the first offset pipe and the second offset delivery pipe are offset, the lower end of the second offset delivery pipe is blocked by the cross-plate, and the first gear and the second gear are offset and no longer meshed. Therefore, in the process of the suction and drainage component transporting the cooling water inside the cooling water tank to the inside of the winding pipe, the ventilation component stops working, and the movement of the cross-plate drives the right-angle rod to move, and the right-angle rod pulls the arc cover plate through the connecting column, so that the arc cover plate and the spray micropore are offset. Since the lower end of the second offset delivery pipe is blocked by the cross-plate, more and more water enters the Z-shaped water pipe, and the water pressure gradually increases. The water accumulated inside the Z-shaped water pipe will be ejected through the spray micropores, and the fire is extinguished by the water spray. The present invention has a simple structure, a clever design, and good linkage. It provides good safety protection for transformer equipment in the power generation operation management system and has high use value and application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Furthermore, the first linkage component 82 includes a hanging plate 825 fixed to the top of the protective frame 1 and a first shaft 823 fixed to the inner wall of the protective frame 1. The outer wall of the hanging plate 825 and the end of the first shaft 823 are both rotatably connected to a first pulley 821. A first transmission belt 824 is connected between the two first pulleys 821. The first pulley 821 located on the upper side is coaxially fixed with the fan 814, and the outer wall of the first pulley 821 located on the lower side is fixed to a first gear 822. The second linkage component 83 includes a bracket 836 and a second shaft 837 fixed on the inner wall of the protective frame 1. The bracket 836 extends to the inside of the mounting cavity 841, and a second pulley 834 is rotatably connected to the outer wall of the bracket 836 and the end of the second shaft 837.

[0058] In addition, the suction and drainage component 85 includes a motor 851 and a shell 854 fixedly installed at the bottom of the protective frame 1. An impeller is provided inside the shell 854. The output shaft on the motor 851 rotates and extends to the inside of the shell 854 and is fixedly connected to the impeller.

[0059] In this embodiment, initially, the second offset pipe 72 coincides with the center axis of the first offset pipe 71 (e.g., Figure 5 As shown), power is turned on and the motor 851 is started. The motor 851 drives the impeller (not shown) inside the housing 854 to rotate through its output shaft. Under the action of centrifugal force, the high-speed rotating impeller sucks the cooling water inside the cooling water tank 7 through the water inlet end 855 and discharges the cooling water into the water inlet pipe 32 through the water outlet end 853.

Example

[0061] See also Figures 1-8 The equipment intelligent operation analysis method and device based on the power generation operation management system include all the contents of Example 1. In addition, an electric telescopic rod 5 electrically connected to the smoke sensor 4 is fixedly installed on the inner wall of the protective frame 1. One end of the electric telescopic rod 5 is fixedly connected to the cross-section plate 84 through the connecting block 51.

A plurality of arc-shaped cover plates 62 are slidingly sleeved on the two limiting slide grooves 67. The outer wall of the Z-shaped water pipe 63 on the upper side of each arc-shaped cover plate 62 is evenly opened with spray micropores 66. The bottom ends of the arc-shaped cover plates 62 in the same row are fixedly connected to a right-angle rod 65 through a connecting column 64. The right-angle rod 65 is fixedly connected to the top of the cross-plate 84, and the Z-shaped water pipe 63 is fixedly installed on the inner wall of the protective frame 1 through a fixed limiting frame 61.

[0063] Furthermore, a lap groove 15 for inserting the cross-section plate 84 is opened on the inner wall of one side of the cavity 11, and a sliding cavity for sliding the cross-section plate 84 is opened inside the protective frame 1, and a spherical sealing gasket 16 is embedded in the lap groove 15 and the inner wall of the sliding cavity.

[0064] In this embodiment, when a fire occurs in the transformer 2, the smoke sensor 4 detects smoke and controls the electric telescopic rod 5 to retract, so that the electric telescopic rod 5 pulls the cross-plate 84 through the connecting block 51, so that the cross-plate 84 passes through the cavity 11 and is inserted into the overlap groove 15. With the cooperation of the spherical sealing gasket 16, the cavity 11 is partitioned by the cross-plate 84, thereby achieving isolation between the inside and outside of the protective frame 1, thereby preventing oxygen from continuously flowing into the protective frame 1 and causing a larger fire.

[0065] In this embodiment, after the cross-plate 84 is inserted into the overlap groove 15, the first offset pipe 71 and the second offset delivery pipe 72 are offset, the lower end of the second offset delivery pipe 72 is blocked by the cross-plate 84, and the first gear 822 and the second gear 831 are offset and no longer mesh. Therefore, in the process of the suction and drainage component 85 transporting the cooling water inside the cooling water tank 7 to the inside of the winding pipe 3, the ventilation component 81 stops working, and the movement of the cross-plate 84 will drive the right-angle rod 65 to move, and the right-angle rod 65 pulls the arc cover plate 62 through the connecting column 64, so that the arc cover plate 62 and the spray micropore 66 are offset. Since the lower end of the second offset delivery pipe 72 is blocked by the cross-plate 84, more and more water enters the Z-shaped water pipe 63, and the water pressure gradually increases. The water accumulated inside the Z-shaped water pipe 63 will be ejected through the spray micropore 66, and the fire is extinguished by water spray.

[0066] Furthermore, it is worth noting that the present invention provides further monitoring and protection for transformers within a power generation operation and management system, improving operational safety. In practical applications, the system can also monitor the operation of other equipment within the system. It can perform logical judgment on both digital and analog inputs, output a delayed, integrated alarm point, push alarm messages via a human-machine interface (HMI) and app, and record the information in a database to generate alarm statistics. The logical judgment process can be edited online through the HMI, allowing staff to modify the judgment logic based on actual needs. The logical judgment can include comprehensive alarms such as over-limit alarms, abnormal temperature rise alarms, over-limit actuation alarms, operating time alarms, abnormal oil / water pump rotation times, decreased oil / water pump efficiency, abnormal oil pressure drop alarms, and false alarm detection for field signals. For example, for an over-limit alarm, a timer begins when one or more conditions are met, and an over-limit alarm is triggered after a specified time has elapsed. (The specific process is conventional and will not be elaborated upon here.)

[0067] Example 1: If the temperature analog value of the first coil of transformer phase A is greater than 50°C with a delay of 2s, or the temperature analog value of the second coil of transformer phase A is greater than 50°C with a delay of 2s, the integrated alarm point will output the transformer phase A high temperature alarm and record it.

[0068] Example 2: When the oil level analog value is less than 300mm, the oil level at the output comprehensive alarm point is lower than the limit.

[0069] Example 3: When the unit is in power generation mode, the flow meter analog value is less than 10m³ / s with a delay of 2s, and a low flow abnormality alarm is output at the integrated alarm point.

[0070] In the present invention, based on the existing transformer over-limit alarm, the technical solutions of embodiment 1 and embodiment 2 are used to further improve the heat dissipation function of the transformer in the power generation operation management system, and after the alarm signal is issued, once a fire occurs, the fire can be controlled in a timely manner.

[0071] Working principle and use process: Initially, the second offset pipe 72 and the first offset pipe 71 are aligned with each other (e.g. Figure 5As shown), the arc-shaped cover plate 62 completely blocks and seals the spray micropores 66 located on its upper side. After that, the power is turned on and the motor 851 is started. The motor 851 drives the impeller (not shown) inside the housing 854 to rotate through its output shaft. Under the action of centrifugal force, the high-speed rotating impeller sucks the cooling water inside the cooling water tank 7 through the water inlet end 855 and discharges it into the water inlet pipe 32 through the water outlet end 853. The cooling water is then transported to the winding pipe 3 through the water inlet pipe 32, and heat is exchanged between the winding pipe 3 and the outer wall of the transformer 2. The water after heat exchange is discharged into the spray mechanism 6 through the drain pipe 31. The water discharged from the drain pipe 31 enters the Z-shaped water pipe 63, flows into the second offset pipe 72 through the Z-shaped water pipe 63, and the second offset pipe 72 flows into the first offset pipe 71 through the connecting hole 842, and finally returns to the cooling water tank 7, forming a cycle to achieve water cooling of the transformer 2.

[0072] When the suction and drainage component 85 is working, it will also use the first bevel gear 852 and the second bevel gear 856 to drive the second pulley 834 located on the lower side to rotate. Under the action of the second transmission belt 835, the two second pulleys 834 rotate synchronously, and the second pulley 834 drives the sleeve 832 to rotate through the star shaft 833. The sleeve 832 drives the first gear 822 to rotate through the second gear 831. The first gear 822 drives the fan 814 to rotate under the action of the first transmission belt 824 and the two first pulleys 821 to suck the air inside the protective frame 1 to achieve air cooling of the transformer 2. In addition, since the first through slot 12 and the second through slot 14 are staggered in the vertical and horizontal directions, while achieving ventilation, it is well prevented from external dust and water vapor from entering the interior of the protective frame 1.

[0073] When a fire occurs in the transformer 2, the smoke sensor 4 detects smoke and controls the electric telescopic rod 5 to retract, causing the electric telescopic rod 5 to pull the cross-section plate 84 through the connecting block 51, so that the cross-section plate 84 passes through the cavity 11 and is inserted into the overlap groove 15. With the cooperation of the spherical sealing gasket 16, the cross-section plate 84 separates the cavity 11, thereby isolating the inside and outside of the protective frame 1 and preventing oxygen from continuously entering the protective frame 1 and causing a larger fire.

[0074] In addition, after the cross-plate 84 is inserted into the overlap groove 15, the first offset pipe 71 and the second offset delivery pipe 72 are offset, and the lower end of the second offset delivery pipe 72 is blocked by the cross-plate 84, and the first gear 822 and the second gear 831 are offset and no longer mesh. Therefore, in the process of the suction and drainage component 85 transporting the cooling water inside the cooling water tank 7 to the inside of the winding pipe 3, the ventilation component 81 stops working, and the movement of the cross-plate 84 will drive the right-angle rod 65 to move, and the right-angle rod 65 pulls the arc cover plate 62 through the connecting column 64, so that the arc cover plate 62 and the spray micropore 66 are offset. Since the lower end of the second offset delivery pipe 72 is blocked by the cross-plate 84, more and more water enters the Z-shaped water pipe 63, and the water pressure gradually increases. The water accumulated inside the Z-shaped water pipe 63 will be ejected through the spray micropore 66, and the fire is extinguished by water spray.

Needless to say, the content protected by the present invention does not involve improvements to software and methods.

10. A method for analyzing equipment intelligent operation based on a power generation operation management system, using the device intelligent operation analysis device based on a power generation operation management system as claimed in any one of claims 8 or 9, characterized in that: The following steps are involved: S1. Initially, the second offset delivery pipe (72) coincides with the central axis of the first offset pipe (71), and the arc-shaped cover plate (62) completely blocks and seals the spray micropores (66) located on its upper side. After that, the power is turned on and the motor (851) is started. The motor (851) drives the impeller (not shown) inside the housing (854) to rotate through its output shaft. Under the action of centrifugal force, the high-speed rotating impeller sucks the cooling water inside the cooling water tank (7) through the water inlet end (855) and discharges the cooling water into the water inlet pipe (32) through the water outlet end (853). The cooling water is transported to the winding pipe (3) through the water inlet pipe (32), and heat exchange is performed between the winding pipe (3) and the outer wall of the transformer (2). The water after heat exchange is discharged into the spray mechanism (6) through the drain pipe (31); S2, the water discharged from the drainage pipe (31) enters the Z-shaped water pipe (63), flows into the interior of the second offset delivery pipe (72) through the Z-shaped water pipe (63), and the second offset delivery pipe (72) flows into the interior of the first offset pipe (71) through the connecting hole (842), and finally returns to the interior of the cooling water tank (7), forming a cycle, thereby achieving water cooling of the transformer (2); S3, when the suction and drainage component (85) is working, it also uses the first bevel gear (852) and the second bevel gear (856) to drive the second pulley (834) located on the lower side to rotate. Under the action of the second transmission belt (835), the two second pulleys (834) rotate synchronously. The second pulley (834) drives the sleeve (832) to rotate through the star shaft (833). The sleeve (832) drives the first gear (822) to rotate through the second gear (831). The first gear (822) drives the fan (814) to rotate under the action of the first transmission belt (824) and the two first pulleys (821), sucking the air inside the protective frame (1) to achieve air cooling for the transformer (2). In addition, since the first through slot (12) and the second through slot (14) are staggered in the vertical and horizontal directions, while achieving ventilation, it is very good to prevent external dust and water vapor from entering the interior of the protective frame (1); S4. When the transformer (2) catches fire, the smoke sensor (4) detects smoke and controls the electric telescopic rod (5) to retract, so that the electric telescopic rod (5) pulls the cross-section plate (84) through the connecting block (51), so that the cross-section plate (84) passes through the cavity (11) and is inserted into the inside of the lap groove (15). With the cooperation of the spherical sealing gasket (16), the cavity (11) is separated by the cross-section plate (84), so as to achieve the isolation between the inside and outside of the protective frame (1), and prevent oxygen from continuously flowing into the inside of the protective frame (1) and causing a larger fire; S5. In addition, after the cross-section plate (84) is inserted into the overlap groove (15), the first offset pipe (71) and the second offset delivery pipe (72) are offset, the lower end of the second offset delivery pipe (72) is blocked by the cross-section plate (84), and the first gear (822) and the second gear (831) are offset and no longer meshed. Therefore, when the suction and drainage component (85) transports the cooling water inside the cooling water tank (7) to the inside of the winding pipe (3), the ventilation component (81) stops working, and the cross-section plate (84) is blocked. 4) will drive the right-angle rod (65) to move, and the right-angle rod (65) will pull the arc cover plate (62) through the connecting column (64), so that the arc cover plate (62) and the spray microhole (66) are misaligned. Since the lower end of the second misaligned delivery pipe (72) is blocked by the cross-section plate (84), more and more water enters the Z-shaped water pipe (63), and the water pressure gradually increases. The water accumulated inside the Z-shaped water pipe (63) will be ejected through the spray microhole (66), and the fire is extinguished by water spray.
