[0002] Combined high and low voltage distribution cabinets, also known as high and low voltage switchgear or high and low voltage electrical equipment, are an important part of modern power systems. They are widely used in industrial, commercial and civil buildings, not only to distribute electrical energy, but also to ensure the safe operation of power systems. High and low voltage distribution cabinets are mainly composed of high voltage distribution equipment and low voltage distribution equipment. In high and low voltage distribution cabinets, if there is an improper influence between the high voltage area and the low voltage area, electromagnetic interference may be generated, which will affect the normal operation of the equipment. Therefore, the research on the comprehensive protection of combined high and low voltage distribution cabinets based on the influence between the high and low voltage transformation areas of the target distribution cabinet is of great significance.

[0003] The existing combined high and low voltage distribution cabinet operation safety monitoring usually refers to the analysis of the output power parameters, ignoring the comprehensive analysis of the spacing between high and low voltage transformation areas, the quality of insulating partitions and the operation quality of transformers. This analysis method may lead to the failure to timely discover the discharge risk caused by unreasonable spacing, and cannot effectively monitor the leakage hazards caused by the quality problems of insulating partitions. It is also difficult to accurately grasp the impact of abnormal transformer operation status on the safe operation of the overall distribution cabinet, making the safety monitoring incomplete, unable to ensure the stable and reliable operation of high and low voltage distribution cabinets from multiple dimensions, and increasing the probability of potential safety accidents.

[0004] The existing combined high and low voltage distribution cabinet operation safety monitoring usually only involves the judgment of abnormal status, but ignores the further analysis of the specific abnormality. This analysis method makes it difficult for the staff to quickly determine whether the problem is in the circuit part, the equipment connection part or other specific areas, reducing the efficiency of troubleshooting. At the same time, due to the lack of understanding of the specific abnormality, it may lead to unnecessary comprehensive inspections, waste a lot of time and manpower costs, and seriously affect the safe and stable operation of the high and low voltage distribution cabinets and the reliability of the entire power system. Summary of the invention

[0005] In view of this, in order to solve the problems raised in the above background technology, a combined high and low voltage distribution cabinet comprehensive protection system and method are now proposed.

[0006] The purpose of the present invention can be achieved through the following technical solutions: The first aspect of the present invention proposes a combined high and low voltage distribution cabinet comprehensive protection system, including: an electrical component spacing analysis module, which is used to use a high-definition camera to collect the electrical component distribution image of the target distribution cabinet, and analyze the electrical component spacing evaluation between the high and low voltage transformation areas of the target distribution cabinet.

If so, further identify the specific anomaly direction.

[0011] The second aspect of the present invention proposes a combined high and low voltage distribution cabinet comprehensive protection method, including: S1, electrical component spacing analysis: using a high-definition camera to collect the electrical component distribution image of the target distribution cabinet, and analyzing the electrical component spacing evaluation between the high and low voltage transformation areas of the target distribution cabinet.

[0012] S2. Line layout spacing analysis: Use a high-definition camera to collect the line layout distribution image of the target distribution cabinet, and analyze the line layout spacing evaluation between the high and low voltage transformation areas of the target distribution cabinet.

[0015] S5. Identification of abnormalities in high and low voltage transformation areas: Based on the evaluation of the electrical component spacing between the high and low voltage transformation areas of the target distribution cabinet, the evaluation of the line layout spacing, the quality of the insulating partitions and the operating quality of the transformer, the impact index between the high and low voltage transformation areas of the target distribution cabinet is analyzed, and then it is determined whether there are abnormalities in the high and low voltage transformation areas of the target distribution cabinet. If so, the specific abnormality is further identified.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) When analyzing the impact index between the high and low voltage transformation areas of the target distribution cabinet, the present invention analyzes the distance between the high and low voltage transformation areas of the target distribution cabinet, the quality of the insulating partition and the operating quality of the transformer.

Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without paying creative work.

[0020] Figure 1It is a schematic diagram of the connection of each module of the system of the present invention.

[0021] Figure 2 It is a schematic diagram of the implementation steps of the method of the present invention. DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 As shown, the first aspect of the present invention provides a combined high and low voltage distribution cabinet comprehensive protection system, including an electrical component spacing analysis module, a line layout spacing analysis module, an insulating partition quality analysis module, a transformer operation quality analysis module and a high and low voltage transformation area abnormality identification module, wherein the electrical component spacing analysis module, the line layout spacing analysis module, the insulating partition quality analysis module, and the transformer operation quality analysis module are all connected to the high and low voltage transformation area abnormality identification module.

[0024] The electrical component spacing analysis module is used to use a high-definition camera to collect the electrical component distribution image of the target distribution cabinet, and analyze the electrical component spacing evaluation between the high and low voltage transformation areas of the target distribution cabinet.

[0025] It should be noted that the distance between electrical components of the target distribution cabinet between the high and low voltage transformation areas affects the operation of the target distribution cabinet: reasonable electrical component distance can prevent different components from interfering with each other during operation. If the distance is too small, it may lead to enhanced electromagnetic interference, degrade the performance of the components, cause malfunctions, signal distortion and other problems, and affect the normal control and monitoring functions of the distribution cabinet. At the same time, too small a distance may also increase the risk of short circuits between components, causing electrical accidents and threatening the safety of equipment and personnel. Properly increasing the distance can improve the stability and reliability of the distribution cabinet operation, ensure the normal service life of electrical components, and ensure that the target distribution cabinet operates safely and efficiently during the high and low voltage transformation process.

[0026] In a preferred embodiment of the present invention, the analysis of the evaluation of the electrical component spacing between the high and low voltage transformation areas of the target distribution cabinet requires the construction of an electrical component spacing evaluation index between the high and low voltage transformation areas of the target distribution cabinet, and the specific analysis method is as follows: extract the electrical component distribution image of the target distribution cabinet collected by a high-definition camera, and then use image processing software to obtain the center point position of each electrical component, recorded as the monitoring position of each electrical component, obtain the distance from the monitoring position of each electrical component to the insulating partition between the high and low voltage transformation areas of the target distribution cabinet, and record it as the monitoring distance of each electrical component.

[0027] The electrical components are classified according to their locations to obtain the electrical components in the high-voltage area and the electrical components in the low-voltage area of ​​the target distribution cabinet. Then, the monitoring distances of the electrical components in the high-voltage area of ​​the target distribution cabinet are averaged and calculated to obtain the monitoring distance of the high-voltage area of ​​the target distribution cabinet, which is recorded as , the monitoring distance of the electrical components in each low-voltage area of ​​the target distribution cabinet is calculated by averaging to obtain the monitoring distance of the low-voltage area of ​​the target distribution cabinet, which is recorded as .

[0028] Using the formula The electrical component spacing evaluation index between the high and low voltage transformation areas of the target distribution cabinet is obtained by analysis ,in Indicates the preset reference high voltage area monitoring distance. Indicates the preset reference low-pressure area monitoring distance. Indicates the permissible difference between the preset high-voltage area monitoring distance and the reference high-voltage area monitoring distance. Indicates the allowable difference between the preset low-pressure area monitoring distance and the reference low-pressure area monitoring distance.

[0029] It should be noted that the pre-set reference high-voltage area monitoring distance and reference low-voltage area monitoring distance are set based on the following: the insulation strength of the insulating materials used in the high and low voltage distribution cabinets determines the setting of the monitoring distance. If the insulating material has good performance and can withstand a higher electric field strength, the monitoring distance can be relatively small; otherwise, the monitoring distance needs to be increased to ensure safety.

[0030] The line layout spacing analysis module is used to use a high-definition camera to collect the line layout distribution image of the target distribution cabinet, and analyze the line layout spacing evaluation between the high and low voltage transformation areas of the target distribution cabinet.

[0031] It should be noted that the line layout spacing between the high and low voltage transformation areas of the target distribution cabinet affects the operating quality of the target distribution cabinet: if the line layout spacing is too small, it is easy to lead to enhanced electromagnetic interference between the lines. Different lines in the high and low voltage areas will generate electromagnetic fields when working. Insufficient spacing will cause these electromagnetic fields to affect each other, which may cause signal distortion, malfunction and other problems, seriously affecting the control accuracy and stability of the distribution cabinet. Reasonable line layout spacing can effectively improve the operating quality of the target distribution cabinet. Appropriate spacing can reduce electromagnetic interference and ensure accurate signal transmission and normal operation of equipment.

[0032] In a preferred embodiment of the present invention, the analysis of the evaluation of the line layout spacing between the high and low voltage transformation areas of the target distribution cabinet requires the construction of an evaluation index for the line layout spacing between the high and low voltage transformation areas of the target distribution cabinet, and the specific analysis method is as follows: extracting the line layout distribution image of the target distribution cabinet using a high-definition camera, using image processing software to obtain each monitoring line parallel to the insulating partition between the high and low voltage transformation areas of the target distribution cabinet, obtaining the monitoring line distance between each monitoring line and the insulating partition, and obtaining the length of each monitoring line.

[0033] It should be noted that when evaluating and analyzing the line layout spacing between the high and low voltage transformation areas of the target distribution cabinet, the reason for selecting the lines parallel to the insulating partitions between the high and low voltage transformation areas of the target distribution cabinet for analysis is: the insulating partitions play a key isolation role between the high and low voltage areas, preventing electrical accidents such as leakage and short circuits between the high and low voltage areas. The distance between the lines parallel to the insulating partitions is most closely related to the insulating partitions. Analyzing them can directly evaluate whether the spacing between the lines and key isolation components is reasonable. If the spacing between these lines and the insulating partitions is too small, it may increase the electric field stress on the insulating partitions, reduce their insulation performance, and thus increase the risk of electrical accidents. On the contrary, a reasonable spacing can ensure that the insulating partitions fully play their isolation role and improve the safety of the distribution cabinet.

[0034] The monitoring lines are classified according to their locations to obtain the monitoring lines of each high-voltage area and each low-voltage area of ​​the target distribution cabinet. The monitoring line distances corresponding to the monitoring lines in each high-voltage area are averaged and calculated to obtain the monitoring line distance in the high-voltage area, which is recorded as , and the monitoring line lengths corresponding to each high-voltage area monitoring line are accumulated and calculated to obtain the high-voltage area monitoring line length, which is recorded as .

[0035] Similarly, the low-voltage area monitoring line distance and the low-voltage area monitoring line length can be obtained, which are recorded as , .

[0036] It needs to be supplemented that the specific analysis method of the low-pressure area monitoring line distance and the low-pressure area monitoring line length is: the monitoring line distance corresponding to each low-pressure area monitoring line is averaged to obtain the low-pressure area monitoring line distance, and the monitoring line length corresponding to each low-pressure area monitoring line is cumulatively calculated to obtain the low-pressure area monitoring line length.

[0037] Using the formula The line layout spacing evaluation index between the high and low voltage transformation areas of the target distribution cabinet is obtained by analysis ,in Indicates the preset reference high voltage area monitoring line distance, Indicates the preset reference low-voltage area monitoring line distance, Indicates the length of the insulating partition between the high-voltage and low-voltage areas of the target distribution cabinet.

[0038] It should be noted that the reference high-voltage area monitoring line distance and the reference low-voltage area monitoring line distance are set based on the following: 1. Different voltage levels have different requirements for monitoring line distances. Generally speaking, the higher the voltage, the greater the required monitoring distance. This is because high voltage will produce a stronger electric field, and a greater distance is required to prevent the electric field from causing harm to the surrounding environment and personnel. For example, the monitoring line distance in the high-voltage area is usually much larger than that in the low-voltage area to adapt to the safety risks brought by high voltage. 2. The performance of the insulating material used in the target distribution cabinet will also affect the setting of the monitoring line distance. If the insulating material has high insulation strength and can withstand large electric field stress, the monitoring distance can be relatively small. On the contrary, if the performance of the insulating material is poor, the monitoring distance needs to be increased to ensure safety. In addition, the aging and wear of the insulating material will also affect its insulation performance, and regular inspection and maintenance are required to ensure the rationality of the monitoring distance.

[0039] The insulating partition quality analysis module is used to use a high-definition camera to collect the apparent quality image of the insulating partition between the high and low voltage transformation areas of the target distribution cabinet, and analyze the quality of the insulating partition between the high and low voltage transformation areas of the target distribution cabinet.

[0040] In a preferred embodiment of the present invention, the analysis of the quality of the insulating partitions between the high and low voltage transformation areas of the target distribution cabinet requires the construction of a quality index for the insulating partitions between the high and low voltage transformation areas of the target distribution cabinet, and the specific analysis method is as follows: extract the apparent quality image of the insulating partitions between the high and low voltage transformation areas of the target distribution cabinet collected by a high-definition camera, and then use image processing software to locate the damaged positions of the insulating partitions, obtain the damaged area of ​​each damaged position, and then perform cumulative calculation to obtain the damaged area of ​​the insulating partitions, and obtain the insulating partition area.

[0041] The difference between the insulating partition area corresponding to the insulating partition between the high and low transformer areas of the target distribution cabinet and the damaged area is calculated to obtain the undamaged area, and then the ratio is calculated with the area of ​​the insulating partition to obtain the insulating partition quality index between the high and low transformer areas of the target distribution cabinet.

[0042] The transformer operation quality analysis module is used to test each transformer of the target distribution cabinet to obtain the electromagnetic leakage impact data of the target distribution cabinet, wherein the electromagnetic leakage impact data includes core quality data and winding quality data, wherein the core quality data specifically includes core volume, core magnetic permeability and monomer spacing, and the winding quality data specifically includes the number of winding turns and the winding geometric center offset distance, so as to analyze the transformer operation quality of the target distribution cabinet.

[0043] It should be noted that the reasons for selecting core volume, core magnetic permeability and monomer spacing as core quality data are: 1. The core volume determines the size of the magnetic flux it can carry to a certain extent. A larger core volume can usually accommodate more magnetic lines of force, thereby providing a stronger magnetic field in electromagnetic equipment, which has a direct impact on the performance of the equipment. 2. Core magnetic permeability is an important parameter for measuring the magnetic conductivity of the core. A core with high magnetic permeability can more effectively concentrate and conduct magnetic fields, reduce magnetic leakage and energy loss. In electromagnetic equipment, such as transformers and inductors, the magnetic permeability of the core directly determines the performance indicators of the equipment, such as efficiency and power factor. 3. In some electromagnetic equipment composed of multiple core monomers, the reasonable setting of the monomer spacing can prevent the core from magnetic saturation. If the monomer spacing is too small, the magnetic fields between adjacent core monomers interfere with each other, which is easy to cause magnetic saturation and a sharp drop in the magnetic conductivity of the core. By controlling the monomer spacing, the magnetic field distribution can be optimized and the working efficiency and stability of the core can be improved.

[0044] It should be supplemented that the core volume can be obtained using a three-dimensional scanning device, the core magnetic permeability can be obtained using a magnetic permeability detection device, and the monomer spacing is obtained by using a three-dimensional scanning device to obtain the distance between the center points of each adjacent core monomer, and then performing mean calculation to obtain it.

[0045] It should be noted that the reasons for selecting the number of winding turns and the offset distance of the winding geometric center as the winding quality data are: 1. The number of winding turns will change the strength and distribution of the magnetic field. The appropriate number of turns can generate the required magnetic field strength to ensure that the equipment operates within the normal working range. At the same time, changes in the number of turns may also cause magnetic field inhomogeneity, which in turn affects the efficiency and stability of the equipment. By monitoring the number of winding turns, abnormalities in the magnetic field distribution can be discovered in time and corresponding adjustment measures can be taken. 2. The offset distance of the winding geometric center will affect the symmetry of the magnetic field. If the geometric center of the winding is offset, it will lead to uneven distribution of the magnetic field, which may cause local overheating, imbalance of electromagnetic force and other problems, thereby affecting the performance and life of the equipment. By monitoring the offset distance of the winding geometric center, this asymmetry can be discovered and corrected in time to ensure the uniformity and stability of the magnetic field.

[0046] It should be added that the method for obtaining the winding geometric center offset distance is: using a three-dimensional scanning device to obtain the geometric center of the high-voltage winding and the geometric center of the low-voltage winding corresponding to each winding, obtaining the distance between the collective center of the high-voltage winding and the geometric center of the low-voltage winding corresponding to each winding, and then performing a mean calculation to obtain the winding geometric center offset distance.

[0047] In a preferred embodiment of the present invention, the analysis of the transformer operation quality of the target distribution cabinet requires the construction of the transformer operation quality index of the target distribution cabinet, and the specific analysis method is as follows: extract the core volume, core magnetic permeability and monomer spacing of the target distribution cabinet, respectively recorded as , , , and then analyze the core quality index of the target distribution cabinet .

[0048] Extract the number of winding turns and the winding geometric center offset distance of the target distribution cabinet, which are recorded as , , and then analyze the winding quality index of the target distribution cabinet .

[0049] The core quality index and winding quality index of the target distribution cabinet are summed up according to the weights to obtain the transformer operation quality index of the target distribution cabinet.

[0050] It should be noted that the weights of the core quality index and the winding quality index of the target distribution cabinet are set based on the following: the core quality and the winding quality have different degrees of influence on the performance of the target distribution cabinet. If the core plays a key role in the functional realization of the distribution cabinet, for example, in a transformer, the magnetic conductivity of the core directly determines the transmission efficiency and stability of electric energy, then the core quality index may be given a higher weight. On the contrary, if the winding has a more significant impact on the performance of the distribution cabinet, such as in determining the accuracy of the output voltage, load capacity, etc., then the weight of the winding quality index may be increased accordingly.

[0051] Exemplarily, the weights of the core quality index and the winding quality index are .

[0052] In a preferred embodiment of the present invention, the specific method of analyzing the core quality index of the target distribution cabinet is as follows: extracting the core volume of the target distribution cabinet , core magnetic permeability and cell spacing , using the formula Analyze and obtain the core quality index of the target distribution cabinet ,in , , They represent the preset reference core volume, reference core magnetic permeability and reference monomer spacing respectively. , , They respectively represent the preset allowable core volume difference, the allowable reference core magnetic permeability difference and the allowable reference monomer spacing difference.

[0053] It should be added that the specific method of analyzing the winding quality index of the target distribution cabinet is: extracting the number of winding turns of the target distribution cabinet and winding geometric center offset distance , using the formula Analyze and obtain the winding quality index of the target distribution cabinet ,in , They represent the preset number of reference winding turns and the offset distance of the reference winding geometric center, respectively. , They respectively represent the preset allowable winding turns difference and the allowable winding geometric center offset distance difference.

[0054] The high and low voltage transformation area abnormality identification module is used to analyze the influence index between the high and low voltage transformation areas of the target distribution cabinet based on the electrical component spacing evaluation, line layout spacing evaluation, insulation partition quality and transformer operation quality between the high and low voltage transformation areas of the target distribution cabinet, and then determine whether there is an abnormality in the high and low voltage transformation areas of the target distribution cabinet, and if so, further identify the specific abnormality direction.

[0055] In a preferred embodiment of the present invention, the specific analysis method of analyzing the influence index between the high and low voltage transformation areas of the target distribution cabinet is as follows: extract the electrical component spacing evaluation index and the line layout spacing evaluation index between the high and low voltage transformation areas of the target distribution cabinet, and then sum them up according to the weight to obtain the spacing evaluation index between the high and low voltage transformation areas of the target distribution cabinet.

[0056] It should be noted that the weights of the electrical component spacing evaluation index and the line layout spacing evaluation index between the high and low transformer areas of the target distribution cabinet are set based on the following: the electrical component spacing and the line layout spacing will affect the performance stability of the target distribution cabinet. For example, inappropriate component spacing may affect the heat dissipation of the components, causing the component temperature to rise, performance degradation or even damage, thereby affecting the overall performance of the distribution cabinet. Unreasonable line layout spacing may affect the quality of signal transmission, leading to control signal distortion, inaccurate monitoring data and other problems. The weight of the corresponding evaluation index is determined by analyzing which spacing problem has a more significant impact on the performance stability of the equipment.

[0057] Exemplarily, the weights of the electrical component spacing evaluation index and the line layout spacing evaluation index between the high and low transformer areas of the target distribution cabinet are: .

[0058] It should be noted that the present invention comprehensively considers the influence of the electrical component spacing and the line layout spacing when analyzing the spacing evaluation between the high and low transformer areas of the target distribution cabinet. This analysis method can ensure that different electrical components will not interfere with each other due to too small spacing during operation, avoids problems such as malfunction, performance degradation, or even damage caused by interference, and ensures the normal operation and service life of the electrical components. On the other hand, considering the line layout spacing can effectively prevent safety hazards such as short circuits and leakages between lines due to unreasonable spacing, and ensure the stability and reliability of power transmission. This comprehensive analysis method comprehensively evaluates the spacing between the high and low transformer areas, and provides a more scientific and accurate basis for the safe and stable operation of the target distribution cabinet.

[0059] Using the formula The influence index between the high and low voltage transformer areas of the target distribution cabinet is obtained by analysis. ,in Indicates the spacing evaluation index between the high and low voltage transformation areas of the target distribution cabinet.

[0060] It should be noted that the present invention analyzes the distance between the high and low voltage transformation areas of the target distribution cabinet, the quality of the insulating partitions and the operating quality of the transformer when analyzing the impact index between the high and low voltage transformation areas of the target distribution cabinet. This analysis method can comprehensively and accurately evaluate the impact between the high and low voltage transformation areas of the target distribution cabinet, and provide a strong guarantee for the safe operation of the distribution cabinet.

[0061] In a preferred embodiment of the present invention, the specific analysis method for determining whether there are abnormalities in the high and low voltage transformation areas of the target distribution cabinet is as follows: extracting the influence index between the high and low voltage transformation areas of the target distribution cabinet, and then comparing it with the pre-set influence index threshold between the high and low voltage transformation areas; if the influence index between the high and low voltage transformation areas of the target distribution cabinet is greater than the influence index threshold between the high and low voltage transformation areas, it is determined that the target distribution cabinet has abnormalities in the high and low voltage transformation areas; otherwise, it is determined that the target distribution cabinet does not have abnormalities in the high and low voltage transformation areas.

[0062] In a preferred embodiment of the present invention, the specific method of identifying specific abnormalities is as follows: extracting the spacing evaluation index between the high and low transformer areas of the target distribution cabinet, the insulation partition quality index between the high and low transformer areas of the target distribution cabinet, and the transformer operation quality index of the target distribution cabinet, and then comparing them with the pre-set spacing evaluation index threshold, insulation partition quality index threshold, and transformer operation quality index threshold, respectively.

[0063] If the spacing evaluation index between the high and low transformer areas of the target distribution cabinet is less than the spacing evaluation index threshold, the specific abnormality is identified as spacing abnormality.

[0064] If the quality index of the insulating partition between the high and low voltage transformation areas of the target distribution cabinet is less than the insulating partition quality index threshold, the specific abnormality is identified as the insulating partition quality abnormality.

[0065] If the transformer operation quality index of the target distribution cabinet is less than the transformer operation quality index threshold, the specific abnormality is identified as abnormal transformer operation quality.

[0066] It should be noted that the specific abnormality may be one or more of abnormal spacing, abnormal insulation partition quality, and abnormal transformer operation quality.

[0067] It should be noted that the present invention further identifies the abnormal direction when judging that there is an abnormality. This analysis method can quickly determine the specific source of the problem after the abnormality is found, avoiding the waste of time and manpower caused by blind investigation. Whether it is a circuit failure, equipment damage or other specific problems, they can be accurately located, making repair and maintenance work more targeted and efficient. It greatly improves the efficiency of troubleshooting, can handle problems in a timely and accurate manner in emergency situations, prevents small problems from turning into major failures, effectively guarantees the safe and stable operation of the target distribution cabinet, and also improves the reliability and stability of the entire power system.
