The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.
[0041] The present application discloses a transformer bushing oil level detection method, which includes some or all of the steps of the following embodiments; that is, the transformer bushing oil level detection method includes some or all of the following technical features. Considering that the regulation of drones or similar commissioning equipment is changing, in one embodiment of the present application, a transformer bushing oil level detection method includes the steps of: S200, transporting an infrared temperature measuring device to a machine; S300, using an infrared temperature measuring device at the machine to perform infrared temperature measurement on the bushing; S400, determining the bushing oil level according to the infrared temperature measurement result. The above transformer bushing oil level detection method cleverly designs the use of infrared temperature measurement to automatically detect the bushing oil level, which has the advantages of reliability and accuracy; the whole process can be automatically completed by a computer, and it is not easy to make mistakes or omissions, and there is no need for staff to climb up and down on site, which not only improves the detection efficiency, but also ensures the safety of staff and reduces work risks, and is also conducive to shortening the detection cycle, thereby improving the timeliness of discovering accidents and saving human resources.
[0042] The concept of this application is proposed mainly in consideration of two trends: one is the accelerated trend of replacing humans with machines, and the other is the changing trend of regulations on drones or similar operational equipment. In one embodiment of this application, a transformer bushing oil level detection method is as follows: Figure 1 As shown, it includes the steps of: S200, transporting the infrared temperature measuring device to the machine; S300, using the infrared temperature measuring device to perform infrared temperature measurement on the bushing at the machine; S400, determining the bushing oil level according to the infrared temperature measurement result. It can be understood that the infrared temperature measuring device performs infrared temperature measurement on the bushing, and the infrared temperature measurement result obtained reflects the temperature distribution inside the bushing. Since the temperature of the transformer oil inside the bushing is higher than that of other parts of the bushing, the bushing oil level can be intuitively reflected. The infrared temperature measurement result is more obvious in winter or cold areas.
[0043] In one embodiment, before step S200, the transformer bushing oil level detection method further includes step S100: pre-setting a machine near the bushing position. Figure 2As shown, it includes the steps of: S100, pre-setting a machine at a position adjacent to the casing; S200, transporting an infrared temperature measuring device to the machine; S300, using the infrared temperature measuring device at the machine to perform infrared temperature measurement on the casing; S400, determining the casing oil level according to the infrared temperature measurement result. In one embodiment, in step S100, the machine is provided with a guide positioning identification part. Furthermore, the guide positioning identification part is used to limit the parking position of the transport device of the infrared temperature measuring device. Such a design is conducive to accurately controlling the position of the transport device of the infrared temperature measuring device, thereby accurately controlling the position of the infrared temperature measuring device relative to the casing to be measured, thereby ensuring the accuracy of the measurement position and the validity of the measurement result.
[0044] In one of the embodiments, in step S200, the infrared temperature measuring device is transported to the machine; further, the machine is used to park the infrared temperature measuring device and its transport equipment, and the transport equipment includes but is not limited to drones. The infrared temperature measuring device is transported by air, which is particularly suitable for bushing oil level detection of large oil-immersed transformers. From the perspective of long-term use, the machine can be equipped with a solar charging module for charging drones and other operational equipment; but this has a slight safety hazard and is generally not recommended. From the perspective of safe use, the machine can be equipped with an elastic bracket or a temporary fixing structure for the drone and other operational equipment to fix the position for a period of time, thereby ensuring that the infrared temperature measuring device is located in a stable measurement environment. Furthermore, in one embodiment, the machine is provided with a temporary fixing structure, and the temporary fixing structure has an open state and a locked state. The temporary fixing structure is used to present the open state for parking the infrared temperature measuring device and its transporting device, and when the infrared temperature measuring device and its transporting device are parked or stopped, the temporary fixing structure changes from the open state to the locked state, and the infrared temperature measuring device and its transporting device are locked as a whole, so that the position of the infrared temperature measuring device and its transporting device is fixed, and the temporary fixing structure is used to change from the locked state to the open state under a preset trigger condition, so that the infrared temperature measuring device and its transporting device can leave the machine without hindrance. In one embodiment, the preset trigger condition includes timing, sensing the rotation of the rotor, and sensing that the top switch is in the abutment state. Such a design is conducive to providing a stable measurement environment for the infrared temperature measuring equipment, ensuring the accuracy of the measurement position and the validity of the measurement results. In addition, the aerial transportation method does not require the staff to climb up and down on site, which also ensures the safety of the staff and reduces the work risk. In conjunction with the embodiment in which the machine is provided with a guiding positioning identification part, it is also conducive to accurately controlling the position of the transport equipment of the infrared temperature measuring equipment, thereby accurately controlling the position of the infrared temperature measuring equipment relative to the sleeve to be measured, further ensuring the accuracy of the measurement position and the validity of the measurement results.
[0045] In one embodiment, in step S200, the infrared temperature measuring device is regularly transported to the machine. In one embodiment, in step S200, the infrared temperature measuring device is regularly transported to the machine by drone. In one embodiment, in step S200, the infrared temperature measuring device is regularly transported to the machine by drone. In one embodiment of the present application, a transformer bushing oil level detection method is as follows Figure 3 As shown, it includes the following steps: S100, pre-setting a machine near the bushing position; S200, transporting the infrared temperature measuring device to the machine by drone; S300, using the infrared temperature measuring device to perform infrared temperature measurement on the bushing at the machine; S400, determining the bushing oil level according to the infrared temperature measurement result. In one embodiment of the present application, a transformer bushing oil level detection method is as follows Figure 4 As shown, it includes the following steps: S100, pre-setting a machine near the casing position; S200, regularly transporting the infrared temperature measuring equipment to the machine by drone; S300, using the infrared temperature measuring equipment to perform infrared temperature measurement on the casing at the machine; S400, determining the casing oil level according to the infrared temperature measurement result. Furthermore, the timing includes daily, every two days, every three days, every week, every ten days, every half month and every month. Such a design is conducive to improving detection efficiency and shortening the detection cycle, thereby improving the timeliness of discovering accidents, which is difficult to achieve with traditional manual inspection methods.
[0046] In one embodiment, after step S200 and before step S300, the transformer bushing oil level detection method further includes step S301: adjusting the position of the infrared temperature measuring device at the machine according to the reference identification portion. Furthermore, the reference identification portion is used to limit the position of the infrared temperature measuring device relative to the top or bottom of the bushing to be measured. At this time, since the height of the infrared temperature measuring device is certain, the parking position of the transport device of the infrared temperature measuring device is limited by the guide positioning identification portion, which can ensure that the measuring orientation of the infrared temperature measuring device is facing the bushing, thereby facilitating the validity of the infrared temperature measurement results. In one embodiment of the present application, a transformer bushing oil level detection method is as follows: Figure 5 As shown, it includes the following steps: S100, pre-setting a machine near the position of the casing; S200, transporting the infrared temperature measuring device to the machine by drone; step S301, adjusting the position of the infrared temperature measuring device at the machine according to the reference mark; S300, using the infrared temperature measuring device at the machine to perform infrared temperature measurement on the casing; S400, determining the casing oil level according to the infrared temperature measurement result. Such a design further standardizes the measurement position of the infrared temperature measuring device, ensures the consistency of the corresponding positions of multiple temperature measurements, and thus ensures the validity and comparability of multiple temperature measurement results.
[0047] In one of the embodiments, in step S300, an infrared temperature measuring device is used at a machine to perform infrared temperature measurement on the bushing; infrared temperature measurement of the bushing using an infrared temperature measuring device can be performed in a conventional manner, and the focus of the present application is that a machine is provided on the oil tank, and infrared temperature measurement is performed at the machine, and this temperature measurement is achieved in an unmanned automated manner. In one of the embodiments, in step S400, the bushing oil level is determined based on the infrared temperature measurement result. In one of the embodiments, in step S300, the infrared temperature measurement result is fed back to a remote server in real time by wireless transmission; and, in step S400, the remote server determines the bushing oil level in real time based on the infrared temperature measurement result. In one embodiment of the present application, a method for detecting the oil level of a transformer bushing is as follows: Figure 6 As shown, it includes the following steps: S100, pre-setting a machine near the casing; S200, transporting the infrared temperature measuring device to the machine; S300, using the infrared temperature measuring device at the machine to measure the casing temperature in infrared, and feeding back the infrared temperature measuring result to the remote server in real time by wireless transmission; S400, the remote server determines the casing oil level in real time according to the infrared temperature measuring result. Such a design is conducive to quickly discovering problems, and is also conducive to cooperating with the subsequent embodiment of taking images around the casing to determine the severity of the problem so as to deal with it in time.
[0048] After the casing oil position is determined according to the infrared temperature measurement result, it can be determined whether the casing oil level is abnormal. For example, when the casing oil level is determined in real time according to the infrared temperature measurement result, it can be determined whether the casing oil level is abnormal. In one embodiment, after step S400, the transformer casing oil level detection method also includes the following steps: S410, when it is determined that the casing oil level is abnormal, a camera device is used to take an image of the surrounding area of the casing; S420, a maintenance requirement is sent and the image capture result is synchronously transmitted. In one embodiment of the present application, a transformer casing oil level detection method is as follows: Figure 7As shown, it includes the following steps: S100, pre-setting a machine at a position adjacent to the casing; S200, transporting an infrared temperature measuring device to the machine; S300, using an infrared temperature measuring device at the machine to perform infrared temperature measurement on the casing, and feeding back the infrared temperature measurement result to a remote server in real time by wireless transmission; S400, the remote server determines the casing oil level in real time according to the infrared temperature measurement result; S410, when it is determined that the casing oil level is abnormal, using a camera to take images of the casing periphery; S420, sending a maintenance request, and synchronously transmitting the image capture result. Further, in step S410, a camera is used at the machine or at a position adjacent to the machine to capture images of the casing periphery. Further, with the casing central axis or close to the central axis as the center, within a radius of 0.5 meters to 1 meter around the casing, the casing periphery is rotated around the casing for one circle to continuously capture images, so as to obtain a comprehensive image capture result of a certain radius around the casing. Such a design can timely determine whether the casing oil level is abnormal. Once an abnormality occurs, more on-site information can be immediately obtained so that the background can make an accurate judgment and take reasonable countermeasures.
[0049] In the above embodiment, step S410 is preferably implemented in conjunction with an embodiment in which a remote server determines the bushing oil level in real time based on infrared temperature measurement results, so that when a problem occurs, it can be discovered in time and more surrounding information can be obtained in time for the background to determine the severity of the problem. In one embodiment, step S420 also includes the step of assigning an emergency level to the maintenance requirement based on the imaging result. In one embodiment of the present application, a transformer bushing oil level detection method is as follows: Figure 8 As shown, it includes the following steps: S100, pre-setting a machine near the casing position; S200, transporting the infrared temperature measuring device to the machine; S300, using the infrared temperature measuring device at the machine to measure the casing by infrared temperature, and feeding back the infrared temperature measurement result to the remote server in real time by wireless transmission; S400, the remote server determines the casing oil level in real time according to the infrared temperature measurement result; S410, when it is judged that the casing oil level is abnormal, using a camera to take pictures of the casing periphery; S420, sending a maintenance demand, synchronously transmitting the image taking result, and assigning an emergency processing level to the maintenance demand according to the image taking result. Such a design clarifies the priority level of the accident situation, is conducive to the reasonable allocation of human resources, and timely adopts reasonable maintenance measures in a reasonable order; especially for emergency treatment after large-scale accidents, it has a good expected effect.
[0050] For inspection and management of a large number of transformers, in one embodiment, after step S400, the transformer bushing oil level detection method further includes step S500: determining the next machine position according to a preset sequence, using the next machine position as the transport destination, and returning to step S200. Fig. 9As shown, it includes the following steps: S200, transporting the infrared temperature measuring device to the machine; S300, using the infrared temperature measuring device to perform infrared temperature measurement on the bushing at the machine; S400, determining the bushing oil level according to the infrared temperature measurement result; S500, determining the next machine position according to a preset sequence, using the next machine position as the transport destination, and returning to execute step S200. In one embodiment of the present application, a transformer bushing oil level detection method is as follows Fig.10 As shown, it includes the steps: S100, pre-setting a machine at a position adjacent to the bushing; S200, transporting an infrared temperature measuring device to the machine; S300, using an infrared temperature measuring device at the machine to perform infrared temperature measurement on the bushing; S400, determining the bushing oil level according to the infrared temperature measurement result; S500, determining the next machine position according to a preset order, using the next machine position as the transportation destination, and returning to execute step S200. The rest of the embodiments are similar and will not be described in detail. Such a design proposes an implementation method for large-scale inspections, such as using drones or similar operational equipment to inspect one by one along the inspection path, automatically detecting the bushing oil level of the transformer, and even automatically determining whether the bushing oil level of the transformer is normal; in practice, a midway charging point can be set up to charge the drone to ensure that it completes the large-scale inspection work, which greatly solves the manpower problem and improves efficiency; in practice, drones can also be used to perform other inspections or tests under the premise of safe operation.
[0051] From the perspective of a closed loop, in one embodiment, after step S400 and before step S500, the transformer bushing oil level detection method further includes step S501: determining whether there is a bushing to be detected, if yes, executing subsequent steps, otherwise transporting the infrared temperature measuring device to the starting position; in one embodiment of the present application, a transformer bushing oil level detection method is as follows Fig.11 As shown, it includes the following steps: S100, pre-setting a machine near the position of the casing; S200, transporting the infrared temperature measuring device to the machine; S300, using the infrared temperature measuring device to perform infrared temperature measurement on the casing at the machine; S400, determining the casing oil level according to the infrared temperature measurement result; S501, judging whether there is a casing to be tested, if yes, executing the subsequent steps, otherwise transporting the infrared temperature measuring device to the starting position; S500, determining the next machine position according to the preset sequence, using the next machine position as the transportation destination, and returning to step S200. This design forms a closed loop, so that the infrared temperature measuring device can return home after completing the infrared temperature measurement of all casings, that is, automatically return home.
[0052] From the perspective of handling emergency situations, in one embodiment, after step S400 and before step S500, the transformer bushing oil level detection method further includes step S502: when it is determined that the priority machine position is received, the priority machine position is used as the delivery destination, and the execution returns to step S200; that is, it is determined whether the priority machine position is received, if so, the priority machine position is used as the delivery destination, and the execution returns to step S200; otherwise, the subsequent steps are continued. In one embodiment of the present application, a transformer bushing oil level detection method is as follows: Fig.12 As shown, it includes the following steps: S100, pre-setting a machine at a position adjacent to the casing; S200, transporting an infrared temperature measuring device to the machine; S300, using an infrared temperature measuring device to perform infrared temperature measurement on the casing at the machine; S400, determining the casing oil level according to the infrared temperature measurement result; S502: when it is determined that a priority machine position is received, the priority machine position is used as the delivery destination, and the execution of step S200 is returned; S500, determining the next machine position according to a preset sequence, using the next machine position as the delivery destination, and returning to the execution of step S200. This design is mainly to consider the sudden emergency during the inspection in sequence. At this time, after completing the infrared temperature measurement of the current casing, the infrared temperature measuring device can be directly transported to the priority machine position to handle the sudden emergency as soon as possible, perform infrared temperature measurement and determine the casing oil level.
[0053] In one embodiment, after step S400, the transformer bushing oil level detection method further includes step S600: outputting the infrared temperature measurement result, the bushing oil level and / or the imaging result.
