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 a device thereof based on a power generation operation management system. Background Art

[0002] The traditional operation handover management of thermal power generation enterprises is still at the stage of handwriting and oral narration, which is inefficient and prone to omissions. The production information that needs to be conveyed during the handover needs to be collected and recorded manually. The information integration and summary of the handover management cannot be automatically realized. The nodes of the handover process are traceless and difficult to trace. There is no process management to regulate the entire handover behavior, and there is no effective real-time supervision method. For this reason, after searching, in the patent document of the equipment operation monitoring method and device based on the power generation operation management system disclosed in the existing patent (Announcement No.: CN114007001B), the camera is installed and disassembled by the suction cup and the air intake structure set on the suction cup, replacing the traditional bolt fixing method, making the installation and disassembly of the camera more convenient, reducing the labor burden of the staff, and also making the camera quickly repaired and replaced after damage, so that the equipment of the power generation operation management system can be more effectively monitored.

[0003] In the above scheme, although the equipment in the power generation operation and management system can be monitored by the monitoring device, it cannot be well protected when the equipment in the power generation operation and management system fails. In the actual power generation operation and management system, the main display terminal is arranged next to the monitoring system operator station, and the plant station is equipped with a terminal extension for synchronous display, which is convenient for the operator to monitor the panel and the maintenance personnel to analyze the equipment. The information on each screen of the system should be highly integrated, and the current alarm information should be displayed in real time, accompanied by an alarm sound prompt. The equipment working data is monitored through the data acquisition device. After the equipment failure alarm occurs, the monitoring personnel can quickly view the fault information.

[0004] In the power generation operation management system, even if the substation transformer monitors the equipment working data through the data acquisition device, the temperature change and the operation of electricity 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 a 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 vertical and horizontal directions, and filter nets 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 delivery pipe coincides with the central axis of the first offset pipe, and the arc-shaped cover completely blocks and seals the spray micropores located on its upper side. After that, 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 transported 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;

[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 of the transformer;

[0027] S3. When the water suction and drainage component is working, it will also use the first bevel gear to drive the second pulley located at 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. 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 to suck the air inside the protection frame to achieve air cooling of 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 protection frame.

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

[0029] S5. In addition, after the cross-section 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-section 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-section 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-section 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 erupt 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] 1. In the present invention, when no fire occurs, the second offset delivery pipe coincides with the central axis of the first offset 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 drainage pipe, and the water discharged from the drainage pipe enters the Z-shaped water pipe, flows into the second offset delivery pipe through the Z-shaped water pipe, and the second offset delivery pipe flows into the first offset pipe through the connecting hole, and finally returns to the cooling water tank, forming a cycle, so as to realize water cooling of the transformer;

[0032] 2. In the present invention, when the water suction and drainage component is working, it will also use the first bevel gear to drive the second pulley located at 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, and the air inside the protective frame is sucked to achieve air cooling of the transformer, further improving 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 is very good to prevent external dust and water vapor from entering the interior of the protective frame;

[0033] 3. In the present invention, when a fire occurs in the transformer, when the smoke sensor detects smoke, it controls the electric telescopic rod to retract, so that the electric telescopic rod pulls the cross-section plate through the connecting block, so that the cross-section plate penetrates the cavity and is inserted into the lap groove. With the cooperation of the spherical sealing gasket, the cavity is partitioned by the cross-section plate, so that the inside and outside of the protection frame are isolated, and oxygen is prevented from continuously flowing into the protection frame to cause a larger fire;

[0034] 4. In the present invention, after the cross-section plate is inserted into the lap 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-section 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-section 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-section 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 erupt through the spray micropores, and the fire is extinguished by water spray. The present invention has a simple structure, ingenious 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

[0059] 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 arranged 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, the outer wall of the shell 854 is fixedly connected with an inlet end 855 and an outlet end 853, the outlet end 853 is fixedly connected with the water inlet pipe 32, the inlet end 855 is fixedly connected with the cooling water tank 7, the outer wall of the output shaft of the motor 851 is fixedly sleeved with 852, one side of 852 is meshedly connected with a first bevel gear 856, and the first bevel gear 856 is fixedly connected to the second pulley 834 located on the lower side.

[0060] In this embodiment, initially, the second offset pipe 72 coincides with the central axis of the first offset pipe 71 (eg, Figure 5 As shown), the power supply 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 tube 3 through the water inlet pipe 32, and the winding tube 3 is used to exchange heat with the outer wall of the transformer 2.

In addition, since the first through groove 12 and the second through groove 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.

[0062] Example 2

[0063] See also Figure 1-Figure 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 a connecting block 51, and the cross-section plate 84 can be pushed and pulled laterally through the electric telescopic rod 5.

[0064] Specifically, the spray mechanism 6 includes a Z-shaped water pipe 63 fixedly connected to the drain pipe 31, one end of the Z-shaped water pipe 63 is fixedly connected to the second offset delivery pipe 72, and two limiting slide grooves 67 are symmetrically opened on the lower outer wall of the horizontal pipe of the Z-shaped water pipe 63. A plurality of arc-shaped cover plates 62 are slidably 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.

[0065] Furthermore, a lap groove 15 for inserting the cross-section plate 84 is formed on the inner wall of one side of the cavity 11, and a sliding cavity for sliding the cross-section plate 84 is formed 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.

[0066] In this embodiment, when a fire occurs in the transformer 2, when the smoke sensor 4 detects smoke, it will control 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 overlap groove 15. With the cooperation of the spherical sealing gasket 16, the cavity 11 is partitioned by the cross-section plate 84 to achieve isolation between the inside and outside of the protective frame 1, thereby preventing oxygen from continuously flowing into the inside of the protective frame 1 and causing a larger fire.

[0067] 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 port 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 meshed. 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 tube 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 port 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 in the Z-shaped water pipe 63 will erupt through the spray micropore 66, and the fire is extinguished by water spray.

[0068] In addition, it is worth noting that the present invention is to further monitor and protect the transformer in the power generation operation management system to improve its safety performance in operation. In the actual power generation operation management system, the operation of the remaining equipment in the power generation operation management system can also be monitored, and the switch quantity and analog quantity can be logically judged and the comprehensive alarm point output after delay can be pushed through the human-machine interface and APP, and the alarm statistical report is recorded in the database. The logical judgment process can be edited online through the human-machine interface, and the staff can modify the judgment logic according to actual needs. Logical judgment may include over-limit alarm, abnormal temperature rise alarm, over-limit alarm of action times, operating time alarm, abnormal warning of oil pump\water pump rotation times, oil pump\water pump efficiency decline, abnormal oil pressure decline alarm and field signal false alarm judgment and other comprehensive alarm contents. For example, for: over-limit alarm: when one or several conditions are met, the timing starts, and the over-limit alarm is triggered after the specified time is exceeded (the specific process is the prior art, which will not be elaborated here).

[0069] Example 1: When the temperature analog value of the first coil of the transformer A phase is greater than 50℃ and the delay is 2s, or the temperature analog value of the second coil of the transformer A phase is greater than 50℃ and the delay is 2s, the comprehensive alarm point outputs the transformer A phase high temperature alarm and records it.

[0070] 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.

[0071] Example 3: The unit is in power generation state, and the flow meter analog value is less than 10m 3 / s and delay 2s, output the low flow abnormal alarm at the comprehensive alarm point.

[0072] In the present invention, on the basis of 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 well controlled in time.

[0073] Working principle and use process: Initially, the second offset pipe 72 coincides with the central axis of the first offset pipe 71 (such as 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. The high-speed rotating impeller, under the action of centrifugal force, 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 transported to the winding pipe 3 through the water inlet pipe 32, and the winding pipe 3 is used to exchange heat with 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;

[0074] When the suction and drainage component 85 is working, it will also use 852 and the first 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, so as to suck the air inside the protective frame 1 and realize air cooling of the transformer 2. In addition, since the first through groove 12 and the second through groove 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.

[0075] 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 lap groove 15. With the cooperation of the spherical sealing gasket 16, the cavity 11 is partitioned by the cross-section plate 84, so that the inside and outside of the protection frame 1 are isolated, and oxygen is prevented from continuously flowing into the protection frame 1 to cause a larger fire;

[0076] 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, 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 meshed. 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 tube 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 in the Z-shaped water pipe 63 will erupt 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 a device intelligent operation analysis device based on a power generation operation management system as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Initially, the second offset delivery pipe (72) and the central axis of the first offset pipe (71) are coincident, and the arc-shaped cover plate (62) completely blocks and seals the spray micropores (66) located on the upper side thereof. Then, the power supply 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 drainage pipe (31); S2, water discharged from the drainage pipe (31) enters the Z-shaped water pipe (63), flows into the second offset delivery pipe (72) through the Z-shaped water pipe (63), and the second offset delivery 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, thereby achieving water cooling of the transformer (2); S3. When the suction and drainage component (85) is working, it also uses (852) and the first bevel gear (856) to drive the second pulley (834) located at 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). Under the action of the first transmission belt (824) and the two first pulleys (821), the first gear (822) drives the fan (814) to rotate, so as to suck the air inside the protection frame (1) and realize air cooling of the transformer (2). In addition, since the first through groove (12) and the second through groove (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 protection 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 lap groove (15). With the cooperation of the spherical sealing gasket (16), the cavity (11) is partitioned by the cross-section plate (84), so that the inside and outside of the protection frame (1) are isolated, so as to prevent oxygen from continuously flowing into the protection 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-shaped cover plate (62) through the connecting column (64), so that the arc-shaped cover plate (62) and the spray micro-hole (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 in the Z-shaped water pipe (63) will be sprayed through the spray micro-hole (66), and the fire is extinguished by water spray.
