Description

Technical Field

[0001] The present invention relates to the field of main transformer monitoring, and in particular to a main transformer intelligent state monitoring device and method based on multi-source data. Background Art

[0002] The main transformer intelligent condition monitoring device of the gas turbine generator set is designed to monitor and evaluate the operating status of the main transformer in real time to ensure its safe and stable operation. The device collects transformer gas parameters in real time through sensors. These parameter data are then processed by an intelligent analysis system to identify potential faults or abnormal conditions.

[0003] A Chinese patent with publication number CN210514171U discloses a gas monitoring device, including a data acquisition instrument and a pump body, a condenser, a dehumidifier, a flow meter and a detector electrically connected to the data acquisition instrument respectively. By adopting a condenser arranged on the gas path, when the airflow to be monitored enters the gas path, the water vapor in the airflow can be condensed under the action of the condenser, and then further water can be removed. By adopting the dehumidifier, the water content of the airflow entering the detector is reduced, thereby improving the dryness and cleanliness of the airflow, so that the detector can monitor the airflow more accurately.

[0004] When the gas monitoring device of the above patent extracts gas, the installation position of the pump body inside the device is fixed, which causes the position of the air inlet of the device to be fixed. The installation orientation and installation position of the device need to compromise the connection of the air inlet, resulting in poor stability of the device after installation, and it cannot adapt to different installation positions and ensure the stability of the gas connection.

A filter screen bonded and fixed to the connecting plate is provided at the lower end between the two adjacent connecting plates, and a limiting plate in contact with the lower end of the connecting plate is provided on the outside of the first transmission pipe at one end facing the filter screen. The gas in the connecting pipe can be completely transmitted to the inside of the first transmission pipe due to the restriction of the limiting plate.

[0008] Preferably, the limiting sheet will contact the lower ends of the two connecting sheets at the same time. The wrapping of the connecting sheets and the protrusion of the limiting sheet can improve the stability of gas transmission and avoid the inability to monitor gas leakage.

[0009] Preferably, a buffer box is welded to the upper end of each of the two monitoring boxes, and one side of the two buffer boxes is sealedly connected to the upper end of the first diversion pipe through the second diversion pipe. The buffering of the buffer box can prevent excess gas from being unable to be transmitted normally and causing blockage inside the equipment.

[0010] Preferably, a second threaded rod is laterally arranged inside the monitoring box, a third threaded rod is laterally arranged inside the buffer box, and guide vanes are mirror-arranged on the outside of the third threaded rod and the second threaded rod, and adjustment of the position of the guide vanes can adjust the flow trajectory of the gas inside the equipment.

[0011] Preferably, one end of the hydrogen sensor is provided with a mounting plate rotatably connected to the upper and lower ends of the monitoring box via a connecting shaft, and the hydrogen sensor is fixed inside the device to contact the gas via the mounting plate.

[0012] Preferably, a sealing ring is arranged around the outside of the mounting plate, and a first threaded rod rotatably connected to the monitoring box is arranged through one of the diagonals of the sealing ring. The position of the sealing ring can be adjusted by rotating the first threaded rod, so that the hydrogen sensor can be exposed outside the equipment.

[0013] Preferably, the outer portion of the first threaded rod is threadably matched with the penetration position of the sealing ring.

[0014] The present invention provides another technical solution: a monitoring system of a main transformer intelligent status monitoring device based on multi-source data: the monitoring system includes a signal conversion module, a signal processing module, an analog-to-digital conversion module, a microprocessor control module, a data comparison module, a communication module, a calibration self-check module and a power management module, wherein:

[0015] Signal conversion module: used to convert chemical reactions into electrical signals, which is the primary conversion stage of signals; signal conditioning module, used to improve signal quality and prepare for subsequent digital processing;

[0016] Analog-to-digital conversion module: used to convert analog signals into digital signals to meet the needs of digital signal processing;

[0017] Microprocessor control module: used to perform data calculation and logic judgment, and is the intelligent center of the hydrogen sensor;

[0018] Data comparison module: used to compare the data calculated by two microprocessor control modules to determine whether they are close;

[0019] Communication module: used to achieve remote data transmission through wires for easy monitoring and control;

[0020] Calibration self-check module: used to maintain the accuracy and reliability of hydrogen sensors, and to detect and solve problems in a timely manner;

[0021] Power management module: used to ensure stable power supply for the sensor to avoid power fluctuations affecting performance.

[0022] The method of the main transformer intelligent condition monitoring device based on multi-source data comprises the following steps:

[0023] For the connecting pipe closest to the exhaust position of the gas turbine generator set, both ends of the pipe are inserted into the connecting pipe and the exhaust position of the gas turbine generator set respectively;

[0024] Step 2: Manually move the monitoring box to rotate between the two housings so that the first transmission pipe is close to the connecting pipe connected to the pipeline in step 1;

[0025] Step 3: The gas in the connecting pipe is directly transmitted to the first transmission pipe through the connection plates on both sides of the connecting pipe and the restriction plates on both sides of the first transmission pipe;

[0026] Step 4: The gas in the first transmission pipe will be actively diverted by the two first diversion pipes, and after flowing into the monitoring box, it will contact the independent hydrogen sensor inside the monitoring box;

[0027] Step 5: After contacting the hydrogen sensor, it will be uniformly discharged from the second transmission pipe position.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The transmission ring of the present invention can directly adjust the directions of the first transmission pipe and the second transmission pipe by rotating between the two shells. The directions are adjusted to enable the overall equipment to rotate according to the gas discharge position after installation to complete adaptation and connection. During the rotation of the first transmission pipe, the gas of the gas turbine generator set is connected to the connecting pipe at the upper end between the two adjacent connecting plates, and the lower end between the two adjacent connecting plates will fit with the limiting plates at the upper and lower ends of the outside of the first transmission pipe, so that the connecting pipe close to the gas connection of the first transmission pipe can receive the gas discharged from the gas turbine generator set. The connection position of the gas transmission pipeline is not directly connected to the first transmission pipe, so as to avoid the shaking of the gas turbine generator set due to the connection of the gas transmission pipeline, which will cause the shaking of the first transmission pipe and the hydrogen sensor inside the monitoring box. Avoiding shaking can improve the accuracy of monitoring.

[0030] 2. The gas received by the first transmission tube of the present invention will be transmitted to the inside of the monitoring box through diversion, and will be monitored simultaneously by the hydrogen sensors between the two monitoring boxes, so as to improve the accuracy of data monitoring. If there are differences in the data, it is convenient for maintenance personnel to discover and correspondingly repair the hydrogen sensors that produce the differences. The buffer box equipped at the upper end of each monitoring box can temporarily supply gas flow and discharge when the hydrogen sensor at the lower end is repaired. When repairing the hydrogen sensor, after rotating the handle in the monitoring box corresponding to the hydrogen sensor, the handle can drive and adjust the position of the upper and lower second threaded rods distributed in a mirror image, so as to adjust the flow direction of the gas, and one of the hydrogen sensors can be repaired without interfering with the monitoring of the other hydrogen sensor.

DETAILED DESCRIPTION

[0042] The present invention is further described below in conjunction with specific embodiments.

[0043] Example 1

[0044] like Fig. 9 As shown, a main transformer intelligent state monitoring device based on multi-source data of this embodiment includes a monitoring system and a hydrogen sensor 27. After the main transformer intelligent state monitoring device is connected to the exhaust port position of the gas turbine generator set, the gas turbine generator set will be discharged during normal operation and actively transmitted to the vicinity of the hydrogen sensor 27, and the hydrogen sensor 27 will actively detect the gas and realize the detection;

[0045] In order to make the equipment adapt to gas turbine generator sets with different shapes and to adapt to the connection between exhaust ports with different orientations and the main transformer intelligent status monitoring device, such as Figure 1 , Figure 3 and Figure 5 As shown, two hydrogen sensors 27 are mirror-imaged, and monitoring boxes 11 are arranged outside the two hydrogen sensors 27. The hydrogen sensors 27 can be wrapped by the monitoring boxes 11, and it is also convenient to guide the transmitted gas. A transmission ring 13 is arranged around the outside of the two monitoring boxes 11, and the front and rear ends of the outside of the transmission ring 13 are provided with a shell 1 for wrapping and protection, and the shell 1 is rotatably connected to the front and rear ends of the transmission ring 13. The transmission ring 13 can be rotated between the two shells 1 to directly adjust the direction, and the rotation can also adjust the direction of the received gas:

[0046] Among them, a first shunt pipe 8 is extended on one side of the two monitoring boxes 11, and one side of the two first shunt pipes 8 is connected by a first transmission pipe 5, and the first transmission pipe 5 penetrates and extends to the inner and outer ends of the transmission ring 13. The exhaust position of the gas turbine generator set transmits the gas to the position of the first transmission pipe 5, so that the gas can be diverted and contact the hydrogen sensor 27 at the same time;

[0047] like Figure 1 , Figure 2 and Figure 4 As shown, connecting pieces 2 are evenly distributed around the two shells 1, nine connecting pieces 2 are arranged around, and the nine connecting pieces 2 are Y-shaped. A connecting pipe 3 is arranged at the upper end between two adjacent connecting pieces 2, and the connecting pipe 3, the connecting piece 2 and the shell 1 are an integrated structure. The exhaust position of the gas turbine generator set can be connected to the connecting pipe 3 at the most convenient connection position, and the direction of the first transmission pipe 5 can be adjusted by rotating it later;

[0048] Among them, a filter screen 7 for filtering large particles is provided at the lower end between two adjacent connecting sheets 2, and the two ends of the filter screen 7 are respectively bonded and fixed to the connecting sheets 2 in contact with each other by glue. When the gas flows into the first transmission pipe 5 through the connecting pipe 3, it will pass through the filter screen 7 and be filtered by the filter screen 7;

[0049] In addition, in order to ensure that the gas can be stably transmitted from the connecting pipe 3 at the connection position to the first transmission pipe 5, a limiting plate 6 is provided at one end of the first transmission pipe 5 facing the filter screen 7, and the limiting plate 6 is in contact with the lower end of the Y-shaped connecting plate 2. Figure 3 and Figure 4 As shown, the limiting sheet 6 will contact the lower ends of the two connecting sheets 2 at the same time. By the limiting sheet 6 contacting the lower ends of the two connecting sheets 2, the gas transmitted by the connecting tube 3 between the two contacting connecting sheets 2 can only be transmitted toward the inside of the first transmission tube 5. The protrusion of the limiting sheet 6 and the shape of the connecting sheet 2 improve the stability of gas transmission, and also facilitate the rotation of the first transmission tube 5 and the arbitrary connection of the connecting tube 3.

[0050] In order to facilitate the device to independently replace one of the hydrogen sensors 27 during the gas detection process without affecting the monitoring of the other hydrogen sensor 27, as shown in FIG. Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the upper ends of the two monitoring boxes 11 are each welded with a buffer box 10, and one side of the two buffer boxes 10 is respectively sealed and connected to the upper end of the first shunt pipe 8 through the second shunt pipe 9. When the hydrogen sensor 27 inside the monitoring box 11 is inspected and repaired, the gas is temporarily discharged from the buffer box 10 through the diversion of the second shunt pipe 9 to avoid the continuous gas flow affecting the inspection and repair of the hydrogen sensor 27;

[0051] Among them, a second threaded rod 21 is transversely arranged inside the monitoring box 11, a second bevel gear 24 is arranged at one end of the second threaded rod 21, and the second bevel gear 24 is welded and fixed to the second threaded rod 21, a third threaded rod 22 is transversely arranged inside the buffer box 10, a first bevel gear 23 is arranged at one end of the third threaded rod 22, and the first bevel gear 23 is welded and fixed to the third threaded rod 22, such as Figure 5 , Figure 6 and Figure 7 As shown, the third threaded rod 22 and the second threaded rod 21 are both provided with guide vanes 20 on the outside, and the two guide vanes 20 are distributed in a mirror image, when one guide vane 20 is away from the first manifold 8, the other guide vane 20 will be close to the second manifold 9, on the contrary, when one guide vane 20 is close to the first manifold 8, the other guide vane 20 will be away from the second manifold 9, and the gas flow trajectory can be adjusted by adjusting the position of the guide vane 20;

[0052] In addition, the guide vane 20 is connected to the third bevel gear 26 through a transmission assembly. Through the transmission of the transmission assembly, the third threaded rod 22 and the second threaded rod 21 can be rotated simultaneously, and the position of the corresponding guide vane 20 can be adjusted at the same time. Figure 5 and Figure 7 As shown, the transmission assembly is composed of two transmission rods 25, two third bevel gears 26, a handle 14, a transmission block 15 and a synchronous belt 16. The two third bevel gears 26 are respectively located on one side of the second bevel gear 24 and the first bevel gear 23, and the third bevel gears 26 are respectively meshed and connected with the second bevel gear 24 and the first bevel gear 23. The transmission rod 25 and the third bevel gear 26 are an integrated structure. By twisting the transmission rod 25, the correspondingly connected third threaded rod 22 and the second threaded rod 21 can be driven to rotate;

[0053] A transmission block 15 is disposed at one end of one transmission rod 25, and a handle 14 is disposed at one end of the other transmission rod 25. The handle 14 and the transmission block 15 are connected to each other through a synchronous belt 16. Through the transmission of the synchronous belt 16 and the extension of the transmission block 15, the lateral position of the guide plate 20 can be adjusted by twisting the handle 14.

[0054] like Figure 6 As shown, the upper and lower ends of the two guide plates 20 are respectively penetrated by fixing rods, and the fixing rods are slidably connected to the inside of the guide plates 20. The third threaded rod 22 and the second threaded rod 21 are restricted by the fixing rods so that after the rotation, the guide plates 20 are transformed from rotational motion to lateral linear motion;

[0055] In order to efficiently expose the hydrogen sensor 27 to the outside of the monitoring box 11 for inspection and replacement, Figure 8 and Fig. 9As shown, a mounting plate 17 is installed at one end of the hydrogen sensor 27, and the upper and lower ends of the mounting plate 17 are rotatably connected to the upper and lower ends of the monitoring box 11 through a connecting shaft 28. In the absence of restrictions, the mounting plate 17 is moved so that the hydrogen sensor 27 can be exposed by rotating around the connecting shaft 28 as the center of the circle;

[0056] The other sides of the two buffer boxes 10 and the two monitoring boxes 11 are sealed and connected by the second transmission pipe 12. The gas flowing into the buffer box 10 and the monitoring box 11 will be uniformly discharged from the second transmission pipe 12 after being monitored. The angle between the center of the second transmission pipe 12 and the first transmission pipe 5 is 180 degrees, so as to prevent the gas discharged from the second transmission pipe 12 from being transmitted to the inside of the first transmission pipe 5.

[0057] Example 2

[0058] In order to avoid the gap between the mounting plate 17 and the monitoring box 11 causing the gas to leak out, Figure 8 As shown, a sealing ring 19 is arranged around the outside of the mounting plate 17, and a first threaded rod 18 is arranged diagonally through one of the sealing rings 19, and one end of the first threaded rod 18 is rotatably connected to the outer wall of the monitoring box 11, and the outside of the first threaded rod 18 is threadedly matched with the position where the sealing ring 19 penetrates, and the rotation of the first threaded rod 18 can drive the sealing ring 19 to move, so that the sealing ring 19 is closely attached to the monitoring box 11 and covers the gap between the mounting plate 17 and the monitoring box 11, and the covering of the sealing ring 19 can prevent the mounting plate 17 from rotating at will, thereby improving the stability of the installation of the hydrogen sensor 27;

[0059] Example 3

[0060] In order to facilitate the protection of the sealing ring 19 and the hydrogen sensor 27, as Figure 2 As shown, a rotatable and detachable cover plate 4 is provided at one end of the outer shell 1, and the inner part of the cover plate 4 is threadedly matched with the outer end of the outer shell 1. After the cover plate 4 is rotated, the position of the sealing ring 19 can be directly exposed.

[0061] Among them, detachable brackets are arranged at the four corners of the outside of the cover plate 4, and the main transformer intelligent status monitoring device can be fixed after the screws pass through the brackets and are embedded in the outer wall of the gas turbine generator set.

[0062] To further understand the content of the present invention, please refer to Fig.10 , this embodiment provides the following technical solutions:

[0063] The monitoring system of the main transformer intelligent condition monitoring device based on multi-source data includes a signal conversion module, a signal ordering module, an analog-to-digital conversion module, a microprocessor control module, a data comparison module, a communication module, a calibration self-test module and a power management module. Among them, the signal conversion module generates an electrical signal when hydrogen reacts with the material inside the sensor, which is used to convert the chemical reaction into an electrical signal and is the primary conversion stage of the signal; the signal ordering module is used to improve the signal quality. The original electrical signal needs to be amplified, filtered or isolated to improve the signal quality and reliability and prepare for subsequent digital processing; the analog-to-digital conversion module is used to convert the analog signal into a digital signal to meet the needs of digital signal processing. The sensor outputs an analog signal, and the analog-to-digital conversion module The block converts these signals into digital signals to facilitate subsequent processing by a digital signal processor or microcontroller; the microprocessor control module is used to perform data calculations and logical judgments, process the converted digital signals, perform data calculations, and make corresponding control decisions based on preset thresholds. It is the intelligent center of the hydrogen sensor 27; the data comparison module is used to compare the data calculated by the two microprocessor control modules to determine whether they are close; the communication module, the hydrogen sensor is usually equipped with a communication interface for remote transmission of data through wires, which is convenient for monitoring and control; the calibration self-test module is used to maintain the accuracy and reliability of the hydrogen sensor 27, and to detect and solve problems in a timely manner; the power management module is used to ensure stable power supply to the sensor to avoid power fluctuations affecting performance.

[0064] The method of the main transformer intelligent condition monitoring device based on multi-source data comprises the following steps:

[0065] Step 1: Rotate and install the bracket to the outer surface of the shell 1. The screws penetrate the shell 1 and are embedded in the installation position to fix the shell 1 and the internal structure. Connect the nearest connecting pipe 3 to the exhaust position of the gas turbine generator set. Insert the two ends of the pipe into the connecting pipe 3 and the exhaust position of the gas turbine generator set respectively.

[0066] Step 2: After rotating the cover plate 4 and exposing the position of the internal monitoring box 11, manually move the monitoring box 11 so that the monitoring box 11 rotates between the two housings 1 under the support of the external transmission ring 13. During the rotation, adjust the first transmission tube 5 and the second transmission tube 12 so that the first transmission tube 5 is close to the connecting tube 3 connected with the pipeline in the connection step 1;

[0067] Step 3: The gas in the connecting pipe 3 is directly transmitted to the first transmission pipe 5 through the restriction of the connecting pieces 2 on both sides of the connecting pipe 3 and the restriction pieces 6 on both sides of the first transmission pipe 5;

[0068] Step 4: The gas in the first transmission pipe 5 will be actively diverted by the two first diverter pipes 8, diverted and flowed toward the two monitoring boxes 11 distributed in mirror image, and after flowing into the monitoring box 11, it will contact the independent hydrogen sensor 27 inside the monitoring box 11;

[0069] Step 5: After contacting the hydrogen sensor 27, the gas will be uniformly discharged from the position of the second transmission pipe 12. The gas at the position of the second transmission pipe 12 will pass through the nearby connecting pipe 3 and be discharged to the outside of the device.

[0070] Working principle: For the connection pipe 3 closest to the exhaust position of the gas turbine generator set, rotate the first transmission pipe 5 so that it faces the connected connection pipe 3. The gas can flow toward the first transmission pipe 5 due to the restriction of the restriction plate 6 and the connection plate 2. The gas inside the first transmission pipe 5 is diverted by the first diversion pipe 8 and transmitted to the corresponding monitoring box 11. After contacting the hydrogen sensor 27 inside the monitoring box 11, the hydrogen sensor 27 generates a signal, which is captured by the signal conversion module and converted into an electrical signal. The signal conditioning circuit processes these signals, and the analog-to-digital conversion module converts the analog signal into a digital signal. The microprocessor control module calculates the hydrogen concentration based on these digital signals. After comparison by the data comparison module, the data is sent to the set position through the communication module. , where the power management module provides stable energy support for all these operations, and the calibration self-test module ensures the long-term stable operation of the sensor. After the data comparison module detects that the data is abnormal, when the abnormal hydrogen sensor 27 is repaired, the handle 14 corresponding to one side of the abnormal hydrogen sensor 27 is rotated, and the handle 14 drives the transmission block 15 to rotate together through the synchronous belt 16. The two transmission blocks 15 will respectively drive the third threaded rod 22 and the second threaded rod 21 to rotate through the transmission rod 25 at one end and the third bevel gear 26, adjust the position of each guide plate 20, so that the gas of the hydrogen sensor 27 at the maintenance position flows toward the buffer box 10, rotate the first threaded rod 18 and adjust the fit of the sealing ring 19, rotate the mounting plate 17, and expose the hydrogen sensor 27.
