Description

Technical Field

[0001] The present application relates to the technical field of power capacitors, and in particular to a design method, device, equipment and storage medium for a power capacitor device. Background Art

[0002] In the high-voltage direct current transmission system, the converter station is the core station used to convert AC into DC or DC into AC, and meet the power system's requirements for safety, stability and power quality. The main equipment in the converter station includes: converter valves, converter transformers, control and regulation systems, filtering equipment, etc. The area occupied by the filtering equipment in the converter station is about one-third of the total area, and its location is close to the factory boundary wall, which has the highest contribution to the factory boundary noise. Among them, the noise pollution problem of power capacitor devices is more prominent.

[0003] In the prior art, the most commonly used noise suppression measure for power capacitor devices in current projects is to reduce the impact of factory boundary noise by installing sound barriers at the factory boundary. SoundPlan simulation based on the sound line method is usually used to calculate the suppression effect of the sound barrier. The specific method is to treat each power capacitor device as an upright line sound source based on the sound power measured in the laboratory of each capacitor, or the sound power estimated based on experience, and continuously adjust the height of the sound insulation wall until the factory boundary noise reaches the noise limit required by the environmental standards. Another noise reduction measure for power capacitor devices is to use sound barrier technology inside the device, specifically to install sound insulation panels on both sides of the same capacitor shelf and / or between two rows of capacitors with opposite bottom surfaces on the same shelf. The internal sound insulation measures increase the structural complexity of the power capacitor device.

[0004] However, it is difficult for both of the above-mentioned two existing technologies to accurately ensure that the factory boundary noise meets the noise reduction requirements, and installing a sound insulation barrier that is too high will also bring safety hazards in terms of wind resistance and earthquake resistance.

[0071] The following will explain in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems through embodiments and in combination with the accompanying drawings. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. It should be noted that the present application Figure 2-Figure 9 The design method of the power capacitor device provided in the embodiment can be executed by a computer device or a design device of the power capacitor device. The design device of the power capacitor device can become part or all of the computer device through software, hardware, or a combination of software and hardware. In the following method embodiments, the execution subject is taken as an example of a computer device.

[0072] In one embodiment, Figure 2 As shown, a design method for a power capacitor device is provided, and the method is applied to Figure 1 The computer device in the embodiment is used as an example to illustrate that the computer device obtains the size information of the capacitor and the arrangement parameters of the capacitor, determines the focus center and the focus radius of each layer of the capacitor group according to the size information of the capacitor and the preset sound wave parameters, determines the focus arc curve of each column of the capacitor group in each layer according to the focus center and the focus radius of each layer of the capacitor group, sets the position of the target sound point of each capacitor on the corresponding focus arc curve according to the arrangement parameters of the capacitor, and obtains the specific process of the simulation model of the power capacitor device, including the following steps:

[0073] S201. Acquire size information of capacitors and arrangement parameters of capacitors; the arrangement parameters include at least the number of layers of capacitors required for the power capacitor device, the number of columns of each layer, and the number of capacitors in each column; the capacitors include a target sounding point.

[0074] The size information of the capacitor refers to the physical size information of the capacitor, including the length, width and height of the capacitor, as well as the floor space and volume calculated based on the length, width and height; the arrangement parameters refer to the arrangement parameters according to the preset rules, which can be referred to Figure 3a , 3b In an electric capacitor device, a multilayer capacitor group is arranged, a plurality of columns of capacitor groups are arranged in each layer of capacitor group, and a plurality of capacitors are arranged in each column of capacitor group; each capacitor includes a main part that emits noise during operation, and the main part is used as a target sound point.

[0075] In this embodiment, the computer device can obtain the size information of the capacitor from the factory parameters corresponding to the capacitor, or scan the capacitor to obtain its size information; the computer device obtains the arrangement parameters of the power capacitor device, and can obtain the pre-set arrangement parameters, or obtain the corresponding arrangement parameters according to the on-site situation, which is not limited to this in this embodiment. In the power capacitor device, each capacitor will make noise when working, and the computer device sets the main sound-generating part as the target sound-generating point, which is used for the subsequent noise field regulation and arrangement steps.

[0076] S202, determining the focus center and focus radius of each layer of capacitor group according to the size information of the capacitor and the preset acoustic wave parameters.

[0077] Among them, the preset sound wave parameters may include a preset sound wave wavelength and the location information of a preset noise-sensitive area, and may also include the noise frequency of the noise emitted when the power capacitor device is in operation. Generally, the sound wave wavelength is determined by the sound speed and the frequency; the focusing center of each layer of capacitor group refers to the center of the same arc where each capacitor in each column of capacitor group is located, and the distance between the bottom center of each capacitor and the focusing center is the focusing radius.

[0078] In this embodiment, the sound speed is a determined value of 340m / s. Generally, the noise frequency range of the power capacitor device is 100-5000Hz. The computer device can obtain the sound wave wavelength of the power capacitor device by calculation. According to the sound wave wavelength and the size information of each capacitor, the computer device can determine the focusing center and focusing radius of each layer of capacitor group by calculation, or analyze and determine the focusing center and focusing radius of each layer of capacitor group from the expert experience system, but this is not limited to this in this embodiment.

[0079] S203, determining the focusing arc curve of each column of capacitor groups in each layer according to the focusing center and focusing radius of each layer of capacitor groups.

[0080] Among them, you can refer to Figure 3c The focusing arc curve refers to the same arc curve where each column of capacitor groups is located, which is determined by the focusing center and focusing radius of each layer of capacitor groups.

[0081] In this embodiment, after obtaining the focusing center and focusing radius of each column of capacitor groups, the computer device can obtain the focusing arc curve of each column of capacitor groups through numerical calculation, and can also obtain the focusing arc curve of each column of capacitor groups through pixel drawing, but this is not limited to this in this embodiment.

[0082] S204. According to the arrangement parameters of the capacitors, the position of the target sound emission point of each capacitor is set on the corresponding focusing arc curve to obtain a simulation model of the power capacitor device.

[0083] Among them, the target sound point of each capacitor is the main part that emits noise when each capacitor is in operation. The target sound point can be located at the center of the bottom of the capacitor, or at the position where the center of gravity of the capacitor is located, that is, the center of the space of each capacitor. The computer equipment arranges each column of capacitor groups on the focusing arc curve according to the position of the target sound point to obtain a simulation model of the power capacitor device that conforms to the preset.

[0084] In this embodiment, the computer device can use the center position of the bottom of the capacitor as the target sound point, arrange the center position of the bottom of each capacitor on the focusing arc curve, and can also use the position where the center of gravity of the capacitor is located as the target sound point, and arrange the position of the center of gravity of the capacitor perpendicular to the ground on the focusing arc curve to obtain a simulation model of the power capacitor device. Furthermore, the sound path difference from the target sound point of the capacitor to the center of the focal circle is 0. In order to achieve the focusing of the noise sound wave, the sound path difference from the center of the focal circle to each capacitor must be equal to kλ (k=0,1,2…), λ is the wavelength of the sound wave. In order to achieve the focusing effect of all frequency noises at the same time, kλ=0, that is, the center of the bottom surface of the capacitor is on the same arc, which is not limited to this in this embodiment.

[0085] In the design method of the above-mentioned power capacitor device, the computer device obtains the size information of the capacitor and the arrangement parameters of the capacitor, determines the focus center and focus radius of each layer of capacitor group according to the size information of the capacitor and the preset sound wave parameters, determines the focus arc curve of each column of capacitor group in each layer according to the focus center and focus radius of each layer of capacitor group, and finally sets the position of the target sound point of each capacitor on the corresponding focus arc curve according to the arrangement parameters of the capacitor to obtain the simulation model of the power capacitor device. In the present application, by determining the focus center and focus radius of each layer of capacitor group according to the size information of the capacitor and the preset sound wave parameters, the focus arc curve of each column of capacitor group in each layer is determined, and the position of the target sound point of each capacitor is set on the corresponding focus arc curve. When the capacitor is running and emitting noise, the effective regulation of the noise sound field of each capacitor is realized, the directionality of the sound field of the power capacitor device is enhanced, and the noise reduction requirements of noise-sensitive areas are met.

[0086] In one embodiment, the position of the target sound emission point of each capacitor is set on the corresponding focus arc curve, including:

[0087] The positions of the target sound emission points of each capacitor are set at equal intervals on the corresponding focusing arc curve; the size information of each capacitor is the same.

[0088] The equal spacing can be for the sides of each capacitor, and the spacing between the sides of each capacitor is the same; it can also be for the bottom center of each capacitor, and the spacing between the bottom centers of each container is the same, and the bottom center is the target sound point position. The size information of each capacitor in the same power capacitor device is the same. In general power capacitor devices, the size information of each capacitor is the same, and it has the characteristics of a repeated array.

[0089] In this embodiment, each capacitor in the power capacitor device has the characteristics of a repeated array, which means that the size information of the capacitors in the power capacitor device is the same, and the arrangement spacing is also the same. For example, the computer device can set the side spacing of the capacitor to 70mm, and then set it on the corresponding focusing arc curve; it can also set the center spacing of the bottom of each container to 70mm, and then set it on the corresponding focusing arc curve. This embodiment is not limited to this.

[0090] In this embodiment, the computer device arranges each capacitor at equal intervals on the corresponding focusing arc curve to meet the characteristic that the capacitors in the power capacitor device are arranged in a repeated array, and the equal interval arrangement standardizes the arrangement distance of each capacitor.

[0091] In one embodiment, the acoustic wave parameters include a preset acoustic wave wavelength and location information of a preset noise-sensitive area; Figure 4 As shown, step 202 "determining the focus center and focus radius corresponding to the arrangement area of ​​each layer of capacitor group according to the size information of the capacitor and the preset acoustic wave parameters" includes:

[0092] S301. Determine the center of a focal circle according to the position information of a preset noise-sensitive area; the sound path difference from the target sound emission point of the capacitor to the center of the focal circle is 0.

[0093] The preset location information of the noise-sensitive area refers to the noise-sensitive area and the non-noise-sensitive area determined according to the location information of the power capacitor device, which can be referred to Figure 5 Area 001 is a noise-sensitive area, and area 002 is a non-noise-sensitive area. Noise-sensitive areas generally include residential areas, campuses, shopping malls and other areas with a large number of residents outside the factory boundary where the power capacitor device is located; non-noise-sensitive areas include areas within the factory boundary where the power capacitor device is located, or fields, wastelands and other areas with a small number of residents outside the factory boundary where the power capacitor device is located.

[0094] In this embodiment, the computer device determines the position of the focus center according to the position information of the noise sensitive area of ​​the preset power capacitor device. For example, if the noise sensitive area is located on the right side of the power capacitor device, the position of the focus center is set on the left side of the power capacitor device, wherein the right side and the left side are relative directions. In other words, the determined area where the focus center is located is a non-noise sensitive area, that is, a direction area away from the noise sensitive area, which is not limited to this in this embodiment.

[0095] S302, determining a focusing radius according to the focusing center, size information of the capacitor, and a preset sound wave wavelength.

[0096] In this embodiment, after obtaining the focal center of each column of capacitor groups, the size information of the capacitors, and the preset acoustic wavelength, the computer device can calculate and determine the focal radius of each column of capacitor groups through the functional relationship between the above parameters, or analyze and determine the focal radius of each column of capacitor groups from an expert experience system. Preferably, the value range of the focal radius is 1 to 10 meters. This embodiment is not limited to this.

[0097] In this embodiment, the computer device determines the center of the focusing circle according to the position information of the preset noise-sensitive area, determines the focusing radius according to the center of the focusing circle, the size information of the capacitor, and the preset sound wave wavelength, and sets the focusing direction of the noise field of the capacitor in a direction away from the noise-sensitive area, which is conducive to weakening the noise field in the noise-sensitive area.

[0098] Taking the above-mentioned capacitor banks including two columns as an example, you can refer to Figure 6 , the arrangement of the first column capacitor group and the second column capacitor group is described. In one embodiment, reference may be made to Figure 6a , 6b , 6c, the opening direction of the focusing arc curve of the first column of capacitor groups is the same as the opening direction of the focusing arc curve of the second column of capacitor groups; or, the opening direction of the focusing arc curve of the first column of capacitor groups is different from the opening direction of the focusing arc curve of the second column of capacitor groups.

[0099] Among them, the opening direction of the focusing arc curve of the first column of capacitor groups is the same as the opening direction of the focusing arc curve of the second column of capacitor groups, and may include the opening directions of the focusing arc curves of the two columns of capacitor groups are both to the left or to the right. It should be noted that left or right is only a relative positional relationship, and does not indicate or imply that it must have a specific orientation, or be designed in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0100] Optionally, the opening direction of the focusing arc curve of the first column of capacitor groups is different from the opening direction of the focusing arc curve of the second column of capacitor groups, and may include: the opening direction of the focusing arc curve of the first column of capacitor groups is opposite to the opening direction of the focusing arc curve of the second column of capacitor groups; or, the opening direction of the focusing arc curve of the first column of capacitor groups is opposite to the opening direction of the focusing arc curve of the second column of capacitor groups.

[0101] In this embodiment, the computer device can set the focusing arc curves of each column of capacitor groups in the power capacitor device according to the structural stability, floor space and location information of the noise-sensitive area of ​​the power capacitor device. For example, the power capacitor device includes two columns of capacitor groups. If the noise-sensitive area of ​​the power capacitor device is located in the vicinity of the right side of the device, the opening directions of the focusing arc curves of the two columns of capacitor groups in the power capacitor device are set to the left; if the noise-sensitive area of ​​the power capacitor device is not located in the vicinity of the device, in order to make the structure of the device more stable, the opening directions of the focusing arc curves of the two columns of capacitor groups in the power capacitor device are set to be opposite or back-to-back. Similarly, it should be noted that left or right is only a relative positional relationship, and does not indicate or imply that a specific orientation or a design must be performed in a specific orientation. Therefore, it cannot be understood as a limitation on the present application, and the present embodiment is not limited to this.

[0102] In this embodiment, the computer equipment can flexibly set the opening direction of the focusing arc curve of the two columns of capacitor groups in the power capacitor device according to the actual situation of the power capacitor device, such as structural stability, floor space and noise-sensitive areas, thereby meeting more structural requirements while meeting noise reduction requirements.

[0103] In one embodiment, Figure 7 As shown, after step 204 of "obtaining a simulation model of the power capacitor device", the method further includes:

[0104] S401. Obtain a simulation diagram of the sound pressure distribution of the power capacitor device.

[0105] Among them, the sound pressure distribution simulation diagram is a simulation model of the power capacitor device. When the power capacitor device is simulated in operation, the sound field pressure distribution diagram of the power capacitor device is obtained. Furthermore, the sound field directivity diagram of the power capacitor device can also be obtained based on the sound field pressure distribution diagram.

[0106] In this embodiment, the computer device simulates the noise emitted when simulating the operation of the simulation model of the power capacitor device, and obtains the sound field pressure distribution diagram for the power capacitor device. From the distribution diagram, the pressure changes of the sound field of the power capacitor device in various directions can be obtained, and the main focusing direction of the sound field of the power capacitor device can also be obtained. This embodiment is not limited to this; for example, the sound field directivity diagram of the power capacitor device is used for illustration, where the 0° direction is the direction facing the wide side of the capacitor. Reference Figure 8a , 8b , 8c, 8d, Figure 8a The directivity diagram of the noise field focus of the above-mentioned power capacitor device when the noise frequency is 500Hz; Figure 8b It is a directivity diagram of the noise field focusing of the power capacitor device in the prior art when the noise frequency is 500Hz; Figure 8c The directivity diagram of the noise field focus of the above-mentioned power capacitor device when it is running at a noise frequency of 1000 Hz; Figure 8d This is a directivity diagram of the noise field focus of the power capacitor device in the prior art when the noise frequency is 1000Hz. The center of the bottom surface of the capacitor in the above power capacitor device is located on a focusing arc with a radius of 2m, and the side spacing of the capacitor unit is set to 70mm; at the same time, the side spacing of the bottom surface of the capacitor unit in the prior art is also set to 70mm. The sound field calculation measurement point is a rectangular plane parallel to the ground with the center of the entire capacitor device as the center. From Figure 8a and 8b It can be seen that when the noise frequency is 500Hz, the above power capacitor device reduces the noise in the direction of the wide side by 5dB compared with the power capacitor device in the prior art; wherein the wide side can be regarded as a horizontal side and is also a noise-sensitive area. Figure 8c and 8d It can be seen that when the noise frequency is 1000 Hz, the noise of the power capacitor device described above is reduced by 6 dB in the direction opposite to the wide side surface compared with the power capacitor device in the prior art.

[0107] S402: Verify, based on the sound pressure distribution simulation diagram, whether the sound field intensity of the target area in the sound field focusing result of the power capacitor device meets a preset sound field intensity value.

[0108] Among them, the target area can be a noise-sensitive area, which generally includes residential areas, campuses, shopping malls and other areas with a large number of residents outside the factory boundary where the power capacitor device is located; the preset sound field intensity value is the sound field intensity value of the pre-set noise-sensitive area.

[0109] In this embodiment, the computer device can obtain the values ​​of a limited number of sound pressure points in a preset coordinate range in the sound pressure distribution diagram according to the sound pressure distribution diagram and the sound field directivity diagram of the power capacitor device obtained by simulation through a sampling method, and use them to calculate the sound field intensity value of the target area; it can also obtain the values ​​of all sound pressure points in the noise-sensitive area corresponding to the sound pressure distribution diagram, and use them to calculate the sound field intensity value of the target area, but this embodiment is not limited to this. The sound field intensity of the target area is obtained by calculation and used to compare with the sound field intensity value of the pre-set noise-sensitive area. Optionally, the sound field calculation measurement point is the center of the capacitor device as a whole, but this embodiment is not limited to this.

[0110] S403. If not, obtain adjustment parameters for adjusting the arrangement of each capacitor according to the sound pressure distribution simulation diagram; the adjustment parameters are used to readjust the arrangement of the capacitors.

[0111] The adjustment parameters refer to parameter information required for adjusting the arrangement of each capacitor, which may include a focusing radius to be adjusted, a focusing center to be adjusted, or a focusing arc curve to be adjusted.

[0112] In this embodiment, if the sound field intensity value of the target area calculated by the computer device does not meet the sound field intensity value of the pre-set noise-sensitive area, the computer device sets the adjustment parameters for adjusting the arrangement of each capacitor according to the distribution of the sound pressure of the target area in the sound pressure distribution simulation diagram; for example, the computer device can set the adjustment parameter to extend the focusing radius by 2 adjustment units in the direction away from the noise-sensitive area according to the distribution of the sound pressure in the target area, and the adjustment unit can be set to 0.5m / adjustment unit; or the adjustment parameter can be set to adjust the center of the focusing circle by 2 moving units in the direction away from the noise-sensitive area, which is not limited to this in this embodiment.

[0113] In this embodiment, the computer equipment simulates the simulation model of the power capacitor device to obtain the sound pressure distribution diagram and the sound field directivity diagram, and verifies whether the sound field intensity in the target area meets the preset sound field intensity based on the sound pressure distribution diagram. If not, the arrangement of each capacitor is adjusted so that the arrangement of each capacitor can obtain the most optimized arrangement.

[0114] S404: Analyze the difference data between the preset sound field intensity value and the sound field intensity of the target area in the sound field focusing result of the power capacitor device according to the sound pressure distribution simulation diagram.

[0115] The difference data may be an adjustment length of a focusing radius, an adjustment displacement of a focusing center, or an adjustment parameter of a focusing arc.

[0116] In this embodiment, the computer device determines that the sound field intensity of the target area does not meet the preset sound field intensity value, analyzes the sound pressure distribution diagram, and obtains the adjustment parameter, which includes the difference data. For example, the computer device sets the adjustment unit to 0.5m / adjustment unit. When the adjustment parameter is the focus radius to be adjusted, the difference data can be the focus radius extended by 2 adjustment units, indicating that the focus radius to be adjusted is increased by 1m away from the noise-sensitive area; when the adjustment parameter is the focus center to be adjusted, the difference data can be the focus center moved by 1 adjustment unit, indicating that the focus radius to be adjusted is moved 0.5m away from the noise-sensitive area, which is not limited to this in this embodiment.

[0117] S405. Determine the focus radius to be adjusted according to the difference data; the focus radius to be adjusted is used to adjust the distance from the position of the target sounding point of each column of capacitor groups to the center of the focus circle.

[0118] In this embodiment, according to the above difference data, the computer device can determine the adjustment method and adjustment result of the focus radius to be adjusted, and according to the adjusted focus radius, the distance from the position of the target sound emission point of each column of capacitor groups to the center of the focus circle is increased. For example, the difference data can be that the focus radius is extended by 2 adjustment units, indicating that the focus radius to be adjusted is increased by 1m away from the noise sensitive area, and at this time, the distance from the position of the target sound emission point of each column of capacitor groups to the center of the focus circle is increased by 1m, and this embodiment is not limited to this.

[0119] In this embodiment, the computer equipment optimizes and adjusts the simulation model of the power capacitor device according to the adjustment parameters, and adjusts the sound field intensity of the target area to whether it meets the preset sound field intensity, so that the arrangement of each capacitor is optimized and the noise-sensitive area obtains the maximum noise reduction.

[0121] In addition, an embodiment of the present application provides a power capacitor device 800, and the power capacitor device 800 is described in detail through several embodiments below. It should be noted that since the power capacitor device 800 is similar to the steps involved in each embodiment of the design method of the power capacitor device provided above, the contents of some embodiments of the power capacitor device 800 can refer to the description of each embodiment of the design method of the power capacitor device provided above, and this embodiment will not be repeated.

[0122] See above Figure 3a , 3b , as shown in 3c, Figure 3a is the front view of the power capacitor device, Figure 3b is a side view of the power capacitor device, Figure 3c The schematic diagram of the arrangement of a layer of capacitor groups is shown in FIG. 8 . The structure of the power capacitor device includes a multilayer capacitor group 801, each layer of capacitor group 801 includes a plurality of column capacitor groups 802; each column capacitor group includes a plurality of capacitors 803. Each capacitor 803 includes a target sounding point 804; the position of the target sounding point 804 is located at the bottom center of each capacitor; the bottom center is the position of the intersection of the bottom diagonal of each capacitor; the positions of the target sounding points 804 of the plurality of capacitors 803 in the column capacitor group 802 are all located on a focusing arc curve 805; the focusing center 806 and the focusing radius 807 corresponding to the focusing arc curve 805 are obtained according to the size information of the capacitor and the preset sound wave parameters; the preset sound wave parameters include the preset sound wave wavelength and the preset position information of the noise sensitive area. Optionally, the size information of each capacitor 803 in the same power capacitor device is the same.

[0123] In this embodiment, the size information of the capacitor 803 refers to the physical size information of the capacitor 803, including the length, width and height of the capacitor, and the floor area and volume calculated based on the length, width and height; in a power capacitor device 800, each capacitor 803 has the same size information, and each capacitor 803 includes a target sounding point 804, which is used to arrange each column of capacitor groups 802 on a focusing arc curve 805 with the same focusing radius 807. The focusing center 806 of each column of capacitor groups 802 refers to the center of the same arc where each capacitor in each column of capacitor groups is located, and the position of the focusing center is determined by the position information of the noise sensitive area of ​​the preset power capacitor device. The bottom center of each capacitor, that is, the distance between the target sounding point 804 and the focusing center 806 is the focusing radius 807. Preferably, the focusing radius 807 ranges from 1 to 10 meters. In this embodiment, since the position of the target sound point 804 of each capacitor is set on the corresponding focusing arc curve 805, when the capacitor 803 is working and emitting noise, the effective regulation of the noise field of each capacitor is achieved, the directionality of the sound field of the power capacitor device is enhanced, and the noise reduction requirements of noise-sensitive areas are met.

[0124] In one embodiment, the sound path difference from the target sound emission point of the capacitor to the center of the focal circle is 0.

[0125] In order to achieve the focusing of the noise sound wave, the acoustic path difference from the focusing center 806 to each column of capacitor groups 802 must be equal to kλ (k=0, 1, 2...), where λ is the wavelength of the sound wave. In order to achieve the focusing effect of all frequency noises at the same time, kλ=0 is required, that is, the capacitor target sound point 804 is on the same focusing arc curve 807.

[0126] In one embodiment, the plurality of capacitors 803 in the column capacitor group 802 are distributed at equal intervals on the corresponding focus arc curve 805 .

[0127] The equidistant distribution may be that the bottom center of each capacitor, i.e., the target sounding point 804, is spaced the same from the bottom center of each capacitor. Optionally, the equidistant distribution may also include that the distances between adjacent sides of adjacent capacitors 803 are equal, or other equidistant arrangement methods. In this embodiment, the plurality of capacitors 803 in the column capacitor group 802 are distributed on the corresponding focusing arc curve 805 at equidistant intervals.

[0128] In this embodiment, the capacitors are arranged at equal intervals on the corresponding focusing arc curve, which satisfies the characteristic that the capacitors in the power capacitor device are arranged in a repeated array, and at the same time standardizes the arrangement of the arrangement distances of the capacitors.

[0129] In one embodiment, Figure 6As shown, if each layer of capacitor group 801 includes a first column capacitor group 8011 and a second column capacitor group 8012;

[0130] Alternatively, if Figure 6a As shown, the opening direction of the focusing arc curve 8051 of the first column of capacitor groups 8011 is the same as the opening direction of the focusing arc curve 8052 of the second column of capacitor groups 8012 .

[0131] The opening direction of the focusing arc curve 8051 of the first column of capacitor groups 8011 is the same as the opening direction of the focusing arc curve 8051 of the second column of capacitor groups 8012, and the opening directions of the focusing arc curves of the two columns of capacitor groups are both to the left or to the right, such as Figure 6a As shown, it should be noted that left or right is only a relative positional relationship, and does not indicate or imply that a specific orientation or design must be performed in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0132] Optionally, the opening direction of the focusing arc curve 8051 of the first column capacitor group 8011 is different from the opening direction of the focusing arc curve 8052 of the second column capacitor group 8012, which may include: Figure 6b As shown, the opening direction of the focusing arc curve 8051 of the first column capacitor group 8011 is opposite to the opening direction of the focusing arc curve 8052 of the second column capacitor group 8012, or, as shown in FIG. Figure 6c As shown, the opening direction of the focusing arc curve 8051 of the first column of capacitor groups 8011 is opposite to the opening direction of the focusing arc curve 8052 of the second column of capacitor groups 8012. This embodiment is not limited to this.

[0133] In this embodiment, the opening directions of the focusing arc curves of the two columns of capacitor groups in the power capacitor device can be flexibly set, thereby meeting more structural requirements while meeting the noise reduction requirements.

[0134] In one embodiment, the preset sound wave parameters include preset sound wave wavelength and preset location information of the noise sensitive area.

[0135] The preset location information of the noise-sensitive area refers to the noise-sensitive area and the non-noise-sensitive area determined according to the location information of the power capacitor device. Figure 5 , area 001 is a noise-sensitive area, and area 002 is a non-noise-sensitive area. Noise-sensitive areas generally include residential areas, campuses, shopping malls and other areas with a large number of residents outside the factory boundary where the power capacitor device is located; non-noise-sensitive areas include areas within the factory boundary where the power capacitor device is located, or fields, wastelands and other areas with few residents outside the factory boundary where the power capacitor device is located. The preset sound wave wavelength is determined by the sound speed and frequency.

[0136] In this embodiment, if the noise sensitive area is located on the right side of the power capacitor device, the focus center is located on the left side of the power capacitor device, wherein the right side and the left side are relative directions. In other words, the determined area where the focus center is located is a non-noise sensitive area, i.e., a direction area away from the noise sensitive area. Generally, the sound speed is a determined value of 340 m / s, the noise frequency of the power capacitor device is 100-5000 Hz, and the sound wave wavelength is determined by the sound speed and the noise frequency, which is not limited to this in this embodiment.

[0137] In one embodiment, as shown in FIG9 , each capacitor 803 includes a target sound emission point 804, and the position of the target sound emission point is located at the bottom center 8040 of each capacitor. Further, the bottom center 8040 is the position of the intersection of two diagonal lines 8041 and 8042 at the bottom of each capacitor.

[0138] The bottom of each capacitor 803 may be in a rectangular shape or a square shape.

[0139] In this embodiment, the intersection of the two diagonal lines 8041 and 8042 at the bottom of each capacitor 803 is the main sound-emitting part when each capacitor 803 is in operation, so the position of the intersection is set as the target sound-emitting point 804 of each capacitor 803, but this is not limited to the present embodiment.

[0140] The structure of the above-mentioned power capacitor device includes a multilayer capacitor group 801, each layer of capacitor group 801 includes a plurality of column capacitor groups 802, each column capacitor group 802 includes a plurality of capacitors 803, each capacitor 803 includes a target sounding point 804, and the positions of the target sounding points 804 of the plurality of capacitors 803 in the column capacitor group 802 are all located on a focusing arc curve 805. By utilizing the characteristics of the repeated sound source array of the capacitor 803 unit in the power capacitor device 800, the position of the target sounding point 804 of each capacitor is set on the corresponding focusing arc curve 805, when the capacitor 803 is working and emitting noise, the effective regulation of the noise sound field of each capacitor is realized, the directionality of the sound field of the power capacitor device is enhanced, and the noise reduction requirements of noise-sensitive areas are met.
