[0001] This invention belongs to the field of noise detection technology, and more specifically, relates to a method for detecting transformer noise. Background Technology

[0002] Numerous transformers exist in cities, providing ample electricity for residents' lives and work. However, while providing power, transformers also generate significant noise, impacting people's lives. Currently, the accuracy of transformer noise detection is low due to the large and irregular distribution of transformers. Summary of the Invention

[0003] The purpose of this invention is to provide a transformer noise detection method to solve the technical problem of low accuracy in transformer noise detection in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a transformer noise detection method, comprising:

[0005] Set multiple transformer locations as multiple detection points;

[0006] With each detection point as the center, multiple auxiliary distribution ring lines are set up around the corresponding detection points;

[0007] The radius of the multiple auxiliary distribution loops gradually increases from the inside to the outside, and each loop is centered at the detection point; the auxiliary distribution loops on any two adjacent detection points do not intersect.

[0008] Multiple first noise monitoring instruments are installed around the detection points on each auxiliary distribution ring line;

[0009] A second noise monitor is installed between the auxiliary ring distribution line outside one detection point and the auxiliary ring distribution line outside another detection point adjacent to the auxiliary ring distribution line. The second noise monitor is collinear with the two adjacent detection points.

[0010] A third noise monitor is installed at the center of the triangle formed by the three adjacent detection points;

[0011] Start the first noise monitoring device, the second noise monitoring device, and the third noise monitoring device;

[0012] Record the noise data from the first noise monitor, the second noise monitor, and the third noise monitor;

[0013] The first, second, and third noise monitors, whose noise data exceeds the environmental noise standard, are labeled noise monitors.

[0014] In one possible implementation, the spacing between the plurality of auxiliary distribution ring lines gradually increases from the inside out.

[0015] In one possible implementation, the number of the first noise monitors on each of the auxiliary distribution ring lines gradually increases from the inside out.

[0016] In one possible implementation, a plurality of the first noise monitoring instruments on each of the auxiliary distribution loops are evenly arranged around the detection point.

[0017] In one possible implementation, the median of the plurality of the marker noise monitors is calculated; and fault detection is performed on the marker noise monitors that are above one-third of the median of the noise data.

[0018] In one possible implementation, the area to be detected is divided into multiple equal-sized squares to form multiple first square regions; each first square region is equipped with at least one first noise monitoring instrument.

[0019] In one possible implementation, the area enclosed by the multiple outer auxiliary distribution ring lines has multiple of the first noise monitors.

[0020] In one possible implementation, the first noise monitor is positioned on the boundary line between two adjacent first square regions.

[0021] In one possible implementation, auxiliary noise monitors are provided on both sides of each of the marker noise monitors.

[0022] In one possible implementation, a fourth noise monitor is set on the straight line between the detection point and each of the marker noise monitors, and the fourth noise monitor is located on the side of the marker noise monitor away from the detection point.

[0023] The beneficial effects of the transformer noise detection method provided by this invention are as follows: Compared with the prior art, the transformer noise detection method of this invention, when monitoring transformer noise, first obtains the accurate locations of multiple transformers from the power supply unit, then uses multiple transformer locations within the entire detection area as detection points, and sets up a virtual auxiliary distribution loop line for each detection point. The outermost auxiliary distribution loop lines of each detection point cannot intersect. Then, multiple first noise monitoring instruments are installed on each auxiliary distribution loop line, with the multiple first noise monitoring instruments arranged around the detection point, so that the noise emitted by the transformer at the detection point can be monitored by the first noise monitoring instruments at each location, improving the accuracy of noise monitoring. Simultaneously, a second noise monitoring instrument is set between the auxiliary distribution loop lines outside two adjacent detection points, ensuring that the second noise monitoring instrument is collinear with the two adjacent detection points. Furthermore, a third noise monitoring instrument is set at the center of the triangle formed by the three adjacent detection points, so that the first noise monitoring instruments and the second noise monitoring instruments... A third noise monitoring device is deployed throughout the entire area to be monitored. Finally, the first, second, and third noise monitoring devices are activated to measure noise data at various locations. After recording the noise data, the data is analyzed. The noise monitoring devices whose data exceed the environmental noise standard are designated as "marked noise monitoring devices." Multiple noise data points from these marked noise monitoring devices are used to identify areas exceeding the noise standard, and noise reduction measures are applied to these areas. In this way, multiple layers of first noise monitoring devices are set up around the monitoring point, with multiple devices on each layer. Then, second and third noise monitoring devices are used to fill the area to be monitored, and the noise data is recorded to generate multiple marked noise monitoring devices to assess environmental noise, thus improving the accuracy of noise monitoring.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] Please see Figures 1 to 3 The transformer noise detection method provided by the present invention will now be described. A transformer noise detection method includes:

[0036] Set the locations of multiple transformers as multiple detection points 1;

[0037] With each detection point 1 as the center, multiple auxiliary distribution ring lines 11 are set up around the corresponding detection point 1;

[0038] The radius of the multiple auxiliary distribution loops 11 gradually increases from the inside to the outside, and all are centered at the detection point 1; the auxiliary distribution loops 11 on any two adjacent detection points 1 do not intersect;

[0039] Multiple first noise monitoring instruments 12 are installed on each auxiliary distribution ring line 11, arranged around the detection point 1;

[0040] A second noise monitor 13 is provided between the auxiliary ring distribution line outside a detection point 1 and the auxiliary ring distribution line outside another detection point 1 adjacent to the auxiliary ring distribution line. The second noise monitor 13 is collinear with the two adjacent detection points 1.

[0041] A third noise monitor 14 is installed at the center of the triangle formed by the three adjacent detection points 1;

[0042] Start the first noise monitor 12, the second noise monitor 13 and the third noise monitor 14;

[0043] Record the noise data from the first noise monitor 12, the second noise monitor 13, and the third noise monitor 14;

[0044] The first noise monitor 12, the second noise monitor 13, and the third noise monitor 14, whose noise data is greater than the environmental noise standard, are marked noise monitors.

[0045] The transformer noise detection method provided by this invention, compared with the prior art, firstly obtains the accurate locations of multiple transformers from the power supply unit when monitoring transformer noise. Then, multiple transformer locations within the entire area to be tested are designated as detection points 1, and a virtual auxiliary distribution loop line is set for each detection point 1. The outermost auxiliary distribution loop line 11 of each detection point 1 must not intersect. Multiple first noise monitoring instruments 12 are then installed on each auxiliary distribution loop line 11, with the instruments arranged around each detection point 1. This ensures that the noise emitted by the transformer at detection point 1 can be detected by the first noise monitoring instruments 12 at each location, improving the accuracy of noise monitoring. Simultaneously, a second noise monitoring instrument 13 is positioned between the auxiliary loop distribution lines outside two adjacent detection points 1, ensuring that the second noise monitoring instrument 13 is collinear with the two adjacent detection points 1. A third noise monitoring instrument 14 is positioned at the center of the triangle formed by the three adjacent detection points 1, so that the first noise monitoring instruments 12, second noise monitoring instruments 13, and third noise monitoring instruments 14 cover the entire area to be tested. The detection area is then assessed. Finally, the first noise monitor 12, the second noise monitor 13, and the third noise monitor 14 are activated. These monitors measure noise data at various locations and record the data. The noise data is then analyzed and identified. Monitors 12, 13, and 14 whose noise levels exceed the environmental noise standard are designated as "marked noise monitors." Multiple noise data points from these marked noise monitors are used to identify areas exceeding the noise standard, and noise reduction measures are applied to these areas. In this way, multiple layers of first noise monitors 12 are set up around detection point 1, with multiple monitors on each layer. Second noise monitors 13 and 14 are then used to fill the detection area, and the recorded noise data generates multiple marked noise monitors to assess environmental noise, thus improving the accuracy of noise monitoring.

[0046] Please see Figures 1 to 3 As a specific embodiment of the transformer noise detection method provided by the present invention, the spacing of multiple auxiliary distribution ring lines 11 gradually increases from the inside to the outside.

[0047] Because the noise is higher near detection point 1 and lower further away from detection point 1, multiple auxiliary distribution loop lines 11 are arranged around detection point 1 to increase the detection efficiency and detection range of the multiple first noise monitoring instruments 12.

[0048] The spacing between the multiple auxiliary distribution ring lines 11 arranged outward from the detection point 1 gradually increases, so that the detection range of the multiple first noise monitoring instruments 12 is wider and the number of first noise monitoring instruments 12 used is smaller.

[0049] Please see Figure 1 and Figure 2 As a specific implementation of the transformer noise detection method provided by the present invention, the number of first noise monitoring instruments 12 on each auxiliary distribution ring line 11 gradually increases from the inside to the outside.

[0050] That is, the number of first noise monitoring instruments 12 on the innermost auxiliary distribution ring line 11 is relatively small, ranging from 3 to 6, or can be increased or decreased according to actual needs.

[0051] The inner diameter of the multiple auxiliary distribution ring lines 11 around the detection point 1 gradually increases. In order to make the monitoring range of each auxiliary distribution ring line 11 more accurate, the number of multiple first noise monitoring instruments 12 on the multiple auxiliary distribution ring lines 11 set outward from the detection point 1 gradually increases.

[0052] The number of first noise monitoring devices 12 on the outermost auxiliary distribution ring line 11 reaches the maximum, at 64-72.

[0053] Please see Figure 2 and Figure 3 As a specific embodiment of the transformer noise detection method provided by the present invention, multiple first noise monitoring instruments 12 on each auxiliary distribution ring line 11 are evenly arranged around the detection point 1.

[0054] Multiple first noise monitoring instruments 12, set on each auxiliary distribution ring line 11, are evenly arranged around the detection point 1 to improve the monitoring effect.

[0055] When arranging multiple first noise monitoring instruments 12, if an obstacle is encountered that affects the placement of the first noise monitoring instruments 12, the instruments should be selectively installed according to the positions of two adjacent first noise monitoring instruments 12, so as to make the detection range of multiple first noise monitoring instruments 12 as uniform as possible.

[0056] Please see Figure 1 As a specific implementation of the transformer noise detection method provided by the present invention, the median of multiple marked noise monitoring instruments is calculated; and fault detection is performed on marked noise monitoring instruments that are higher than one-third of the median of the noise data.

[0057] After organizing and statistically analyzing the noise data from each marker noise monitor, the median of the noise data from multiple marker noise monitors was calculated.

[0058] Furthermore, noise monitors with noise data greater than one-third of the median were identified and subjected to fault detection to avoid inaccurate monitoring due to mechanical failure.

[0059] Please see Figure 1 As a specific implementation of the transformer noise detection method provided by the present invention, the area to be detected is divided into multiple equal-sized squares to form multiple first square areas 15; each first square area 15 is provided with at least one first noise monitoring instrument 12.

[0060] The area to be tested is divided into squares to form multiple relatively standard first-direction areas, which facilitates more accurate and complete monitoring of the entire area to be tested.

[0061] At least one first noise monitor 12 is installed in each first square area 15 to conduct more detailed monitoring in addition to the monitoring of each auxiliary distribution ring line 11.

[0062] After the first noise monitoring device 12 on the auxiliary distribution loop line 11 occupies a first square area 15, other first noise monitoring devices 12 can be selectively placed in the first square area 15.

[0063] Specifically, if the first noise monitoring instrument 12 on the auxiliary distribution ring line 11 occupies the edge position of a first square area 15, then other first noise monitoring instruments 12 can be placed at the center and other edge positions in the first square area 15.

[0064] Specifically, if the first noise monitoring instrument 12 on the auxiliary distribution ring line 11 occupies the center position of a first square area 15, other first noise monitoring instruments 12 can be placed around the perimeter of the first square area 15.

[0065] Please see Figure 1 As a specific embodiment of the transformer noise detection method provided by the present invention, the area enclosed by multiple outer auxiliary distribution ring lines 11 has multiple first noise monitoring instruments 12.

[0066] Considering cost and installation reasons, the adjacent outermost auxiliary distribution ring lines 11 do not intersect, which can easily lead to large areas that cannot be accurately monitored, resulting in the failure of noise monitoring in the entire area to be monitored.

[0067] Therefore, multiple first noise monitoring instruments 12 are set in the area between the multiple outermost auxiliary distribution ring lines 11 to monitor the noise data at various points in the area, so as to achieve the purpose of accurate and error-free monitoring.

[0068] If the positions of the multiple rearranged first noise monitoring instruments 12 conflict with those of the second noise monitoring instruments 13, then the first noise monitoring instruments 12 will not be placed at that location.

[0069] When the positions of the multiple rearranged first noise monitoring instruments 12 are close to those of the first noise monitoring instruments 12 on the auxiliary distribution ring line 11, then the first noise monitoring instruments 12 are also arranged at that location to avoid any monitoring omissions.

[0070] Preferably, a plurality of first noise monitors 12 are evenly arranged in the area between the plurality of outermost auxiliary distribution ring lines 11.

[0071] Multiple first noise monitors 12 are arranged in an arc shape in the area between multiple outermost auxiliary distribution ring lines 11, and the arc line intersects the auxiliary distribution ring line 11 perpendicularly.

[0072] Please see Figure 1 As a specific embodiment of the transformer noise detection method provided by the present invention, a first noise monitoring instrument 12 is set on the boundary line of two adjacent first square regions 15.

[0073] Multiple first square regions 15 are formed, and a first noise monitoring instrument 12 is set in each first square region 15. This method results in a vacuum zone with a certain distance between two adjacent square regions.

[0074] No first noise monitoring instrument 12 is installed in this vacuum zone, but this part of the vacuum zone is far away from the corresponding first square areas 15, so it does not have much impact on the noise monitoring in the first square areas 15.

[0075] Therefore, a first noise monitor 12 is set at the junction of two adjacent first square areas 15, and the data of the first noise monitor 12 in this part is recorded and observed independently.

[0076] Furthermore, it does not participate in the median calculation of the entire area to be tested, which ensures the accuracy of noise monitoring in the area to be tested and avoids the omission or neglect of noise sources.

[0077] Please see Figure 1 and Figure 4 As a specific embodiment of the transformer noise detection method provided by the present invention, auxiliary noise monitoring instruments 16 are set on both sides of each marked noise monitoring instrument.

[0078] Considering factors such as cost and installation, the multiple first noise monitoring instruments 12 on the same auxiliary distribution loop line 11 are spaced far apart, making it impossible to achieve accurate monitoring and resulting in missed detections.

[0079] Therefore, after some of the first noise monitoring instruments 12 are recorded as marked noise monitoring instruments, this area needs to be monitored in a focused manner.

[0080] By placing auxiliary noise monitoring devices 16 on both sides of the marked noise monitoring device, the range of noise monitoring is increased.

[0081] Multiple auxiliary noise monitors 16 are set up, with the corresponding marker noise monitor as the center and the multiple auxiliary noise monitors 16 arranged around the marker noise monitor.

[0082] Please see Figure 1 and Figure 4 As a specific embodiment of the transformer noise detection method provided by the present invention, a fourth noise monitor 17 is set on the straight line between the detection point 1 and each marked noise monitor. The fourth noise monitor 17 is located on the side of the marked noise monitor away from the detection point 1.

[0083] Some of the first noise monitoring devices 12, the second noise monitoring device 13, and the third noise monitoring device 14 are identified as marked noise monitoring devices, and therefore there are areas around these marked noise monitoring devices where the noise level is higher than the environmental noise standard.

[0084] Therefore, in order to more accurately assess the impact of transformer noise on the living environment, a virtual line is drawn through detection point 1 and a marked noise monitor is placed, and a fourth noise monitor 17 is set on the virtual line. The fourth noise monitor 17 is located on the side of the marked noise monitor away from detection point 1, so as to achieve monitoring of a more distant area around the marked noise monitor.

[0085] In this method, there is no need to perform secondary monitoring on the side of the noise monitor closest to detection point 1. Simply setting up a fourth noise monitor 17 improves the accuracy of noise monitoring.

[0086] A fifth noise monitor can be installed on both sides of the fourth noise monitor 17 to monitor both sides of the fourth noise monitor 17, so as to achieve key monitoring of key monitoring areas and avoid missing areas.

[0087] The fourth noise monitor 17 and two fifth noise monitors are located on an arc with the detection point 1 as the center.

[0088] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
