Description

Technical Field

[0001] This invention relates to the field of compact design technology for plug-in current transformers, specifically to a compact design method for plug-in current transformers adaptable to multiple scenarios. Background Technology

[0002] Against the backdrop of miniaturization and modularization in power equipment, pluggable current transformers, as an important component of current detection and power equipment condition monitoring, are widely used in distribution cabinets, power metering devices, and various electrical equipment. As different installation environments place increasingly higher demands on equipment space, installation orientation, and maintenance methods, pluggable current transformers need to adapt to different installation spaces and methods. Traditional pluggable current transformers are typically designed structurally for a single installation scenario, with a relatively fixed internal structural layout and connection structure between the fixed and pluggable parts. This makes it difficult to simultaneously meet the structural dimensions and pluggable space requirements of different installation scenarios.

[0003] However, existing compact design methods for pluggable current transformers typically only reduce volume by shrinking the overall external dimensions or internal structural dimensions. They lack design approaches that analyze structural size constraints in different installation scenarios, making it difficult to tailor the compression and combination of fixed and pluggable parts according to different installation spaces. Furthermore, there is a lack of mechanisms for transferring and centrally arranging easily faulty detachable functional structures in the fixed parts, making it difficult to coordinate maintenance needs with structural compactness. In addition, existing structural designs do not adequately consider the rearrangement of internal structures, the position of pluggable connections, and the coordinated adjustment between connection structures. They also lack continuous analysis of changes in structural spacing and connection dimensions during plugging and unplugging, which can easily lead to structural interference or connection dimensions not meeting connection requirements. Consequently, they are difficult to adapt to different installation space orientations and installation methods in different installation scenarios. Therefore, there is a need to provide a compact design method and system for pluggable current transformers that is adaptable to multiple scenarios to solve the above problems. Summary of the Invention

[0004] To address the aforementioned technical problems, this paper provides a compact design method for pluggable current transformers that is adaptable to multiple scenarios. This technical solution solves the problem that existing compact design methods for pluggable current transformers, as mentioned in the background, typically only reduce the overall external dimensions or internal structural dimensions to achieve volume compression. They lack a design approach that combines structural dimension constraint analysis with different installation scenarios, making it difficult to selectively compress and combine fixed and pluggable parts according to different installation spaces. Furthermore, there is a lack of transfer and centralized arrangement mechanisms for easily faulty detachable functional structures in the fixed part, making it difficult to coordinate maintenance needs with structural compactness. In addition, existing structural designs lack sufficient rearrangement of internal structures, adjustment of pluggable connection positions and coordination between connection structures, and lack continuous analysis of changes in structural spacing and connection dimensions during plugging and unplugging. This can easily lead to structural interference or connection dimensions not meeting connection requirements, making it difficult to adapt to different installation space orientations and installation methods in different installation scenarios.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A compact design method for pluggable current transformers adaptable to multiple scenarios includes: Obtain multiple installation scenarios corresponding to pluggable current transformers, and determine the structural size limitations corresponding to different installation scenarios based on the installation space of each installation scenario; The pluggable current transformer is structurally disassembled to obtain a fixed part and a pluggable part. The fixed part and the pluggable part are compressed and combined to obtain a combined structure. The size is checked in combination with the structural size constraints to obtain an initial compact structure. The internal functional structures of the fixed part of the initial compact structure are screened, and the detachable functional structures that are prone to failure are transferred to the pluggable part. The spatial changes after the transfer of functional structures are determined, and a functional centralized structure is obtained. Based on the functional centralized structure, the internal structure of the fixed part and the pluggable part is rearranged, and the pluggable connection position and the connection structure between the fixed part and the pluggable part are adjusted to obtain a compact structure. Based on the compact structure, the structural dimensions between the fixed part and the pluggable part, as well as the connection dimensions between them, are checked, and the compact structure is adjusted to obtain the target compact structure. Based on the target compact structure, the installation position relationship between the fixed part and the pluggable part is determined, and combined with the installation methods corresponding to different installation scenarios, the compact design results of the pluggable current transformer under different installation scenarios are obtained.

[0006] Furthermore, a compact design system for pluggable current transformers adapted to multiple scenarios is proposed to realize the compact design method for pluggable current transformers as described above, including: The installation scenario module is used to acquire multiple installation scenarios corresponding to the pluggable current transformer, extract boundaries and analyze dimensions based on the installation space of each installation scenario, and determine the structural dimension limitations corresponding to different installation scenarios. The structural compression module is used to disassemble the pluggable current transformer to obtain a fixed part and a pluggable part. The module extracts the dimensions and analyzes the space occupation of the fixed part and the pluggable part, identifies the space redundancy position, and performs size reduction and position convergence to obtain an initial compact structure. The functional integration module is used to divide the internal structure and analyze the connection relationship of the fixed part of the initial compact structure, screen the detachable functional structures that are prone to failure and transfer them to the pluggable part, and collect the empty space and arrange the functional structures in a concentrated manner according to the spatial changes after the functional structure is transferred, so as to obtain the functional integration structure. The structural layout module is used to match the connection ends and analyze the connection paths of the internal structures in the fixed part and the pluggable part according to the functional centralized structure, move the position of the internal structure corresponding to the cross connection path, and determine the pluggable connection position and adjust the connection structure according to the connection end arrangement data to obtain a compact structure. The plug-in / plug-out adjustment module is used to determine multiple plug-in / plug-out positions of the pluggable part along the plug-in / plug-out direction according to the compact structure, calculate the structural spacing and connection dimension changes at each plug-in / plug-out position, and adjust the structural outline dimension and connection dimension according to the dimension interference position to obtain the target compact structure. The installation adapter module is used to determine the installation position relationship between the fixed part and the pluggable part according to the target compact structure, and to adjust the installation position and combine the installation structure according to the installation space direction and installation method corresponding to different installation scenarios, so as to obtain the compact design results of the pluggable current transformer under different installation scenarios.

[0007] Compared with the prior art, the beneficial effects of the present invention are: This solution proposes a compact design method for pluggable current transformers that adapts to multiple scenarios. By acquiring multiple installation scenarios corresponding to the pluggable current transformer, analyzing the installation space of each scenario, determining structural size constraints, and structurally disassembling and compressing the pluggable current transformer to form an initial compact structure, the structural compression process can be adjusted according to the space requirements of different installation scenarios, thereby improving the overall compactness of the pluggable current transformer structure and its adaptability to different installation spaces. This solution proposes a compact design method for pluggable current transformers that is adaptable to multiple scenarios. By screening the internal functional structures of the fixed part, the faulty detachable functional structures are transferred to the pluggable part. The spatial changes after the functional structure transfer are analyzed, the empty space in the fixed part is gathered, and the transferred functional structures are arranged in a centralized manner to form a functional centralized structure. This concentrates the faulty detachable functional structures in the pluggable part, while realizing the reuse of the internal space of the fixed part and improving the coordination between the compact design and the maintenance of the detachable functional structures. This solution proposes a compact design method for pluggable current transformers that is adaptable to multiple scenarios. By rearranging the internal structure of the fixed and pluggable parts, matching and analyzing the connection paths of the connection terminals, moving the internal structures with intersecting connection paths, determining the pluggable connection positions and adjusting the connection structures, a compact structure is formed. This coordinates the internal structure layout with the connection relationship between the fixed and pluggable parts, reduces the overlap of connection paths and unreasonable pluggable connection positions, and improves the layout rationality of the compact structure. This solution proposes a compact design method for pluggable current transformers that adapts to multiple scenarios. By determining multiple pluggable positions along the pluggable direction, the method calculates the changes in structural spacing and connection dimensions under different pluggable positions, identifies dimensional interference positions, and adjusts the structural outline and connection dimensions. Simultaneously, it adjusts the installation position relationships and installation structure combinations for different installation scenarios, forming a compact design result corresponding to different installation scenarios. This enables the compact structure to adapt to both the pluggable process and the installation requirements under different installation scenarios, thereby improving the multi-scenario adaptability of pluggable current transformers.

Detailed Implementation

[0009] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0010] Reference Figure 1 -Figure 4 As shown in the figure, a compact design method for pluggable current transformers adapted to multiple scenarios according to an embodiment of the present invention includes: Obtain multiple installation scenarios corresponding to pluggable current transformers, and determine the structural size limitations corresponding to different installation scenarios based on the installation space of each installation scenario; Specifically, before designing a compact plug-in current transformer, installation scenario information is collected based on the actual usage location and installation conditions. For example, for plug-in current transformers used inside switchgear, the installation location, surrounding equipment layout, available installation space, installation surface direction, and pluggable operation direction can be obtained from the switchgear's internal layout diagram, equipment installation diagram, and on-site measurement records. For switchgear of different models or structures, the lateral, longitudinal, and height spaces inside the corresponding cabinet are recorded, along with the spatial relationship between the fixed installation location and the pluggable operation side. For equipment already in operation, the actual installation dimensions and surrounding structural locations can be obtained from on-site survey records. For equipment not yet installed, the reserved installation space can be determined based on the equipment structure diagram and installation design drawings. Installation conditions with similar or identical installation locations, spaces, directions, and methods are grouped into the same installation scenario, while installation conditions with different installation space directions, locations, or methods are classified into different installation scenarios, thus forming scenario data corresponding to multiple installation scenarios. For example, the installation conditions of front insertion / removal inside the cabinet, side insertion / removal inside the cabinet, and installation restricted by the upper structure are respectively regarded as different installation scenarios. The installation space range, fixed position, insertion / removal direction and surrounding structure position corresponding to each installation scenario are recorded to provide scenario basis for subsequent determination of the structural size restrictions corresponding to each installation scenario.

[0011] The pluggable current transformer is structurally disassembled to obtain a fixed part and a pluggable part. The fixed part and the pluggable part are compressed and combined to obtain a combined structure. The size is checked in combination with the structural size constraints to obtain an initial compact structure. The internal functional structures of the fixed part of the initial compact structure are screened, and the detachable functional structures that are prone to failure are transferred to the pluggable part. The spatial changes after the transfer of functional structures are determined, and a functional centralized structure is obtained. Based on the functional centralized structure, the internal structure of the fixed part and the pluggable part is rearranged, and the pluggable connection position and the connection structure between the fixed part and the pluggable part are adjusted to obtain a compact structure. Based on the compact structure, the structural dimensions between the fixed part and the pluggable part, as well as the connection dimensions between them, are checked, and the compact structure is adjusted to obtain the target compact structure. Based on the target compact structure, the installation position relationship between the fixed part and the pluggable part is determined, and combined with the installation methods corresponding to different installation scenarios, the compact design results of the pluggable current transformer under different installation scenarios are obtained.

[0012] Furthermore, the pluggable current transformer is structurally disassembled to obtain a fixed part and a pluggable part. The fixed part and the pluggable part are then compressed and combined to obtain a combined structure. Dimensional verification is performed based on structural size constraints to obtain an initial compact structure, specifically including: Obtain the installation space dimensions corresponding to each installation scenario, and perform boundary extraction and dimension analysis on the installation space to determine the length, width, and height limits corresponding to each installation scenario, thereby obtaining the structural dimension limits; The connection method of the internal structure in the pluggable current transformer is identified, and the internal structure with fixed connection is divided into fixed part and the internal structure with detachable connection is divided into pluggable part. The dimensions of the fixed and pluggable parts are extracted, and the space occupancy relationship of each internal structure is analyzed to obtain structural space occupancy data; Specifically, when designing a compact plug-in current transformer for different installation scenarios, the first step is to obtain the actual available space dimensions for arranging the plug-in current transformer at each installation location. This is then combined with the distribution of surrounding cabinet structures, partitions, busbars, and adjacent equipment to determine the actual usable area of ​​the installation region. During processing, the starting and ending boundary positions of the installation region in the length, width, and height directions are determined. The structural positions that restrict the further arrangement of the plug-in current transformer in the corresponding directions are used as the spatial boundaries in those directions, thus creating corresponding spatial boundary data for each installation scenario. For example, when installing a pluggable current transformer inside a switch cabinet, the measured length, width, and height of the reserved area in the cabinet are 180mm, 120mm, and 150mm. However, a busbar is installed on one side in the width direction, and the actual usable distance from the outer side of the busbar to the other side of the cabinet is only 100mm. In this case, the side of the busbar closest to the installation area is taken as the limiting boundary in the width direction, and 100mm is taken as the actual usable space in that direction. If there is a partition above the installation area, and the lower surface of the partition is 130mm from the installation reference surface, then the lower surface of the partition is taken as the limiting boundary in the height direction, thus forming the corresponding length, width, and height space boundary data.

[0013] Subsequently, dimensional analysis was performed on the spatial boundary data corresponding to each installation scenario. The distances between relative boundaries in the length, width, and height directions were calculated respectively. Based on the actual available distances in each direction, the dimensional constraints of the plug-in current transformer in the corresponding directions were determined, forming length, width, and height constraints. These three dimensional constraints together constitute the structural dimensional constraints. For example, for the switchgear installation scenario mentioned above, if the distance between the two boundaries in the length direction is 180mm, the distance in the width direction is 100mm due to busbar constraints, and the distance in the height direction is 130mm due to partition constraints, then the length constraint for this installation scenario is determined to be 180mm, the width constraint to be 100mm, and the height constraint to be 130mm. When in another installation scenario the available distance in the length direction is 200mm, the available distance in the width direction is 140mm, but the available distance in the height direction is only 110mm due to the internal partitions, then 110mm is taken as the height dimensional constraint for this installation scenario. This allows the spatial constraints corresponding to different installation scenarios to participate in subsequent structural adjustments and dimensional verifications.

[0014] After determining the boundaries and dimensional limitations of the installation space, the connection methods of each component structure within the pluggable current transformer are identified, and the structure is classified based on the actual disassembly relationships of the internal structures during insertion, removal, maintenance, and repair. When an internal structure forms a fixed connection with an adjacent structure and maintains its original installation position when the pluggable part is inserted or removed, that internal structure is classified as a fixed part. When an internal structure can be disconnected from an adjacent structure and detaches from its original position during maintenance, replacement, or repair, that internal structure is classified as a pluggable part. For example, if the iron core and fixed support structure in a switchgear are fixed to the cabinet installation position with screws and remain stationary during insertion and removal, it is classified as a fixed part. If the winding assembly is connected to the fixed support structure through a detachable connection end and can detach from the fixed support structure with the pluggable part when removed, it is classified as a pluggable part.

[0015] When multiple internal structures are interconnected and participate in the insertion and removal process together, the division is determined based on their connection relationship. When multiple internal structures can be detached from the fixed part together, they are collectively classified as the pluggable part, so that the pluggable part corresponds to the range of structures that move synchronously during the actual insertion and removal process. For example, if the winding assembly, connecting terminals, and terminal supports in the pluggable part move together in the same direction during the removal process, then all three are classified as pluggable parts; the support base, which is fixedly connected to the cabinet and whose position does not change, is classified as the fixed part. This ensures that the internal structure division is consistent with the structural movement relationship during the actual insertion and removal process.

[0016] After dividing the fixed and pluggable parts, the dimensions of each internal structure in both parts are extracted to determine the actual dimensions, arrangement, and spacing of each internal structure in the length, width, and height directions. The overall outline of the two parts is then determined based on the actual connection and arrangement relationships between the internal structures, resulting in the dimensions of the fixed structure and the pluggable structure, respectively. During the dimension extraction process, the relative positions and spacing between the internal structures are preserved so that the resulting dimensional data reflects the overall spatial range of the two parts in their actual combined state. For example, if a winding fixing structure is installed above the support base in the fixed part, with a 10mm gap between them, this gap is simultaneously retained in the dimensions of the fixed structure. Similarly, when the winding assembly and connecting terminals in the pluggable part are arranged on the same side, the overall outline dimension in that direction is determined based on their actual arrangement, rather than simply superimposing the independent dimensions of the two structures.

[0017] Subsequently, the dimensions of the fixed and pluggable structures are spatially mapped according to the actual combination relationship between the fixed and pluggable parts. The actual occupied areas of each internal structure in the length, width, and height directions are determined, and the spatial relationships between different structures are identified. When two internal structures are arranged adjacently, their adjacency and relative spacing are recorded. When there is an area between two internal structures that is not occupied by other structures, the spatial range of this area is determined and associated with the adjacent internal structure. For positions where the fixed and pluggable parts are combined, the spatial occupied range and relative positional relationship of the two parts are retained. For example, if the support base and winding fixing structure in the fixed part are arranged sequentially along the length direction, and there is a 15mm unoccupied space between them, this area is recorded as a spatial interval. If the winding assembly, connecting terminals, and terminal supports in the pluggable part are concentrated on one side of the length direction, while the other side forms a 20mm unused area, this spatial range and its positional relationship with adjacent structures are recorded simultaneously. After the above size occupancy analysis, the actual occupied area, adjacent relationships and structural intervals of each internal structure are unified into structural space occupancy data, which provides a basis for subsequent identification of space redundancy locations and size reduction and position convergence.

[0018] Based on the structural space occupancy data, the space redundancy positions in the fixed and pluggable parts are identified, and the internal structures corresponding to the space redundancy positions are reduced in size and compacted in position to obtain the fixed and pluggable parts after structural compression. The relative positions between the fixed and pluggable parts after the structure is compressed are determined, and the structure is combined according to the determined relative positions to form the connection position between the fixed and pluggable parts, thus obtaining the combined structure. The overall dimensions of the composite structure are calculated to obtain the dimensions of the composite structure. The dimensions of the combined structure are checked against the structural size constraints, and the structural positions that do not meet the structural size constraints are corrected to obtain the initial compact structure.

[0019] Understandably, after the structural space occupancy data is generated, the internal structural space in the fixed and pluggable parts is analyzed. Combining the spacing between adjacent structures and the structural outline, areas not actually occupied by functional components, connecting structures, or installation structures are identified. Spacing areas that do not contribute to structural connections, functional layout, or pluggable movement are designated as spaces to be compressed; external extensions of the internal structure that do not participate in functional layout are designated as reducible structural areas. For example, if there is a 15mm gap between the support base and the winding fixing structure in the fixed part, and this area has no connecting ends or other structures, it is designated as a space redundancy location; if there is a 20mm extension outside the winding assembly in the pluggable part that does not participate in functional layout, this area is designated as a structural area that can be reduced in size. Further verification is performed based on the connection relationships of adjacent structures to confirm that compression will not change the connection position or enter the movement range of the pluggable part.

[0020] After determining the location of spatial redundancy, the dimensions of the relevant internal structures are reduced or their positions are tightened based on the location of the redundant space. When the redundant space is located between two internal structures, one of the structures is moved towards the adjacent structure while maintaining their original connection positions. When the redundant space is located in the extended area of ​​the structure's outer contour, the outer contour of the structure in the corresponding direction is reduced, while keeping the internal functional areas and connection positions unchanged. For example, the 15mm gap between the support base and the winding fixing structure is reduced to 5mm, retaining the adjustment result without structural overlap and while keeping the connection positions unchanged. For the 20mm extension area outside the winding assembly, its outer contour dimensions are reduced. After the adjustment is completed, the structural arrangement range of the two parts is redefined, resulting in the compressed fixed part and pluggable part.

[0021] Subsequently, the compressed fixed part and the pluggable part are aligned according to their actual insertion / removal relationship. The direction of movement of the pluggable part is determined, and the distance and placement of the two parts are adjusted based on the relative positions of each connection point, so that the connected structures correspond. For example, when the pluggable part is inserted into the fixed part horizontally, the corresponding connection terminals are aligned along the insertion direction; when there are multiple connection ends, the overall position of the pluggable part is adjusted so that each connection end can be aligned simultaneously. After the position alignment is completed, the two parts are combined to form a combined structure with corresponding connection positions.

[0022] After the combined structure is formed, the overall length, width, and height dimensions are determined based on the outermost structural positions of the fixed and pluggable parts in the combined state. These dimensions in each direction are then compared with the dimensional constraints of the corresponding installation scenario. When a dimension exceeds the limit in a certain direction, the internal structure forming the outermost boundary in that direction is located, and the adjustment position is determined based on the spatial relationship between this structure and adjacent structures. For example, if the width constraint of an installation scenario is 100mm, while the width of the combined structure is 108mm, then the width direction exceeds the limit by 8mm, and the internal structures forming the two side boundaries are examined. If one side has a 5mm structural extension area not involved in functional layout, and the other side has a 4mm retractable gap, then the outer contour is reduced and the position is retracted, respectively.

[0023] After adjustments are made, the dimensions of the combined structure in three directions are recalculated and compared again with the dimensional constraints of the corresponding installation scenario. If all three dimensions are within the constraints and the connection positions between the fixed and pluggable parts remain unchanged, the adjusted structural state is retained. If any dimensions still exceed the limits, the boundary structures in the corresponding directions are repositioned and adjusted. For example, after a 5mm reduction in the outer profile and a 3mm reduction in the structure width, the combined structure width is adjusted from 108mm to 100mm. The length and height directions are then checked to ensure they do not exceed the corresponding dimensional constraints. The adjusted fixed, pluggable, and connection positions are then retained to form the initial compact structure.

[0024] Furthermore, the internal functional structures of the fixed part of the initial compact structure are screened, and the easily faulty detachable functional structures are transferred to the pluggable part. The spatial changes after the functional structure transfer are determined, resulting in a functionally centralized structure, specifically including: The fixed part in the initial compact structure is divided into internal structural units to obtain multiple internal structural units. The connection ends of each internal structural unit are extracted, and the connection relationship between each internal structural unit and the adjacent internal structure is analyzed. The internal structural units that are only connected to the adjacent internal structure through detachable connection ends are identified as detachable functional structures. Fault records are extracted from the connecting ends and functional components in the detachable functional structure, and the connecting ends and functional components are marked according to the fault records to obtain the fault location corresponding to each detachable functional structure. Specifically, after the initial compact structure is formed, the actual arrangement of the functional structures within the fixed section is examined, and the fixed section is divided according to the installation positions, functional component distribution, and interconnections between the structures. During processing, functional areas are gradually identified from one side of the fixed section along the internal structural arrangement direction. When functional components within a certain area form a relatively complete structural combination and connect to adjacent structures through clearly defined connection points, that area is divided as an internal structural unit, and the corresponding structural boundary is determined. For cases where multiple functional components are tightly combined and jointly perform the same structural function, the relevant functional components are retained within the same internal structural unit. When adjacent functional structures can be relatively independently separated through connection points, they are distinguished according to the connection points, thus forming multiple internal structural units with clearly defined structural boundaries.

[0025] For example, within a fixed section, a support structure, a core structure, and a winding mounting structure are arranged sequentially along the installation direction. The core structure and the winding mounting structure have clearly defined connection points and each has its own independent component arrangement area. Therefore, the core structure and the winding mounting structure are divided into structural boundaries along the corresponding connection points, forming different internal structural units. If an internal structural unit contains multiple mutually fixed support and positioning components, and these components are always treated as a whole during maintenance, then the support and positioning components are grouped into the same internal structural unit. After division, each internal structural unit is numbered to facilitate subsequent identification of the connection relationships between them.

[0026] After the internal structural units are divided, the positions where each internal structural unit connects to adjacent internal structures are examined, and the corresponding connection ends are extracted from the actual connection locations. During processing, the areas connecting to other internal structures are examined along the structural boundary of each internal structural unit. When a location serves as an electrical, mechanical, or structural positioning point between two internal structures, that location is designated as the connection end of the corresponding internal structural unit, and the location of the connection end and the adjacent internal structures connected to it are recorded. If a single internal structural unit has multiple connection locations, each connection end is extracted separately, establishing a one-to-one correspondence between different connection ends and their corresponding connected objects.

[0027] For example, if one side of an internal structural unit is electrically connected to an adjacent winding structure via a terminal, and the other side is mechanically connected to a support structure via a screw connector, then the terminal location and the screw connection location are recorded as the two connection ends corresponding to the internal structural unit, and the connection objects corresponding to the two connection ends are also recorded. When another internal structural unit is connected to three adjacent structures at the same time, the three connection positions are extracted respectively, so that each connection end retains its own position and corresponding connection object, avoiding multiple connection positions being merged into one connection end.

[0028] After extracting the connection ends, the connection ends of each internal structural unit are traced to adjacent structures to examine the actual structural objects and connection methods connected to the corresponding connection ends. When a connection end forms a fixed connection with an adjacent internal structure, the connection relationship is recorded as a fixed connection relationship; when a connection end can be detached by releasing the connector or separating the connection structure, the corresponding relationship is recorded as a detachable connection relationship. Subsequently, all connection ends and corresponding connection objects of the same internal structural unit are summarized, so that each internal structural unit forms a complete connection relationship with adjacent internal structures; for cases where there are connections with multiple adjacent internal structures simultaneously, the connection relationships corresponding to each connection end are retained separately.

[0029] For example, if an internal structural unit is connected to an adjacent supporting structure by screws and to another adjacent structure by plug-in terminals, the fixed connection relationship corresponding to the screw connection and the detachable connection relationship corresponding to the plug-in terminals are recorded respectively. If the internal structural unit is also connected to the cabinet through another fixed support, the fixed connection relationship corresponding to that connection end is recorded, so that the internal structural unit forms connection relationship data containing multiple connection ends and corresponding connection objects.

[0030] After clarifying the connection relationships of each internal structural unit, all connection ends corresponding to the same internal structural unit are examined uniformly to determine whether there are any fixed connections that cannot be detached. If all connection ends are detachable, and the internal structural unit can be completely separated from adjacent internal structures after each connection end is removed, then the internal structural unit is identified as a detachable functional structure. If any connection end remains fixed, restricting the internal structural unit from being detached from the fixed portion, then the internal structural unit remains within the fixed portion. By simultaneously examining the connection methods of all connection ends, structures that can be completely detached from the fixed portion are identified.

[0031] For example, if an internal structural unit has two connection ends, one of which is connected to an adjacent structure via a plug-in terminal and the other is connected to a supporting structure via a detachable fastener, and the internal structural unit can be completely removed from the fixed part after the two connection ends are disconnected, then it is identified as a detachable functional structure. If another internal structural unit has three connection ends, two of which are detachable, but the third connection end is fixedly connected to the cabinet via a fixed connector, and it still cannot be detached from the fixed part after the other two connection ends are disconnected, then it is not identified as a detachable functional structure, but remains in the fixed part.

[0032] After the detachable functional structure is determined, historical fault records related to this structure are compiled. Based on the fault object, location, and handling information recorded in the fault records, the corresponding connection end or functional component where the fault occurred is located. During processing, fault records are first filtered according to the detachable functional structure's number. Then, the fault object is read and matched with the connection end and functional component within the detachable functional structure. When a fault record corresponds to a connection end, the location of that connection end is marked as the fault location; when it corresponds to a functional component, the location of that functional component is marked as the fault location. If multiple fault records exist for the same location, all records are retained for subsequent statistics on the number of fault occurrences at that location.

[0033] For example, a detachable functional structure numbered F03 contains two connection ends and one functional component. If three historical maintenance records show a contact abnormality at one of the connection ends, these three records are mapped to the location of that connection end. Similarly, two records show a malfunction in the functional component, which are also mapped to the location of that functional component. For other faulty objects recorded in maintenance records, they are mapped according to their names and actual installation locations within the detachable functional structure. Once the locations of multiple historical fault records are mapped, the locations of faulty records in each connection end and functional component are summarized to form the corresponding fault locations for each detachable functional structure.

[0034] Based on the fault location, the number of faults corresponding to each fault location is counted, and the number of faults in the same detachable functional structure is summarized. Detachable functional structures whose number of faults reaches the preset fault screening threshold are identified as detachable functional structures prone to failure. The detachable functional structure that is prone to failure is removed from the fixed part and transferred to the pluggable part. The space occupancy of the fixed part and the pluggable part after the transfer is calculated and compared with the space occupancy data before the transfer to obtain the space change data. Based on spatial change data, the empty space formed after the functional structure in the fixed part is transferred is gathered together, and the transferred functional structures in the pluggable part are centrally arranged to obtain a functional centralized structure.

[0035] Specifically, after mapping each fault location, the number of fault records for different fault locations is accumulated, and the corresponding times for each fault location belonging to the same detachable functional structure are summarized to form the fault occurrence count for each detachable functional structure. For example, in a certain detachable functional structure, if the fault location corresponding to the plug terminal experiences 3 faults and the fault location corresponding to the winding component experiences 2 faults, then the fault occurrence count for this detachable functional structure is 5. After completing the count statistics for all detachable functional structures, each detachable functional structure is arranged from low to high fault occurrence count, and the average fault occurrence count for all detachable functional structures is calculated. Then, the fault screening threshold is determined by combining the number of structures above the average and the change in fault occurrence count. When the fault occurrence count of a certain detachable functional structure reaches twice or more of the average, the corresponding count can be used as the fault screening threshold to distinguish between frequent fault structures and low-frequency fault structures; alternatively, based on the change in fault occurrence count after arrangement, the location where there is a significant jump in the number of fault occurrences between the high-fault-count structure and the previous structure can be used as the screening location, and the higher fault occurrence count can be used as the fault screening threshold. For example, if a statistical analysis shows that the failure frequencies of five detachable functional structures are 1, 2, 2, 5, and 6, respectively, with an average failure frequency of 3.2, then the screening threshold can be determined by combining the average value and the jumps in the failure frequency. This method ensures that the failure screening threshold is determined by the statistical results of actual failure records, rather than by directly assigning a fixed value.

[0036] When the number of failures corresponding to a certain detachable functional structure reaches the failure screening threshold, it is identified as a detachable functional structure prone to failure; structures that do not reach the threshold are retained in the fixed part, so that subsequent structures are transferred to functional structures with more frequent failures.

[0037] After identifying the detachable functional structures prone to failure, the detachable connections between these structures and the fixed parts are sequentially released to separate the detachable functional structures from adjacent internal structures. Once all connections have been released, the functional structure is removed from its original installation position, maintaining the relative positions of its connection ends and functional components. For example, if a detachable functional structure is connected to the fixed part via two plug-in terminals, the connections of the two plug-in terminals are released, and the functional structure is moved away from the fixed part to prevent it from remaining connected to it.

[0038] After the functional structure is removed from the fixed part, the arrangement of each structure inside the pluggable part is examined, and an installation area sufficient to accommodate the transferred functional structure is determined. Subsequently, the detached, fault-prone functional structure is moved to its corresponding installation area, aligning its connection end with the corresponding connection position in the pluggable part, and its position is adjusted according to the internal arrangement direction of the pluggable part. For example, if the original fault-prone functional structure was located at the bottom of the fixed part, while the terminal support structure in the pluggable part was located near the pluggable side, the fault-prone functional structure is moved to an adjacent position to the terminal support structure, allowing it to move synchronously with the pluggable part along the pluggable direction. This forms the fixed part and pluggable part after the structure transfer.

[0039] After the functional structure is transferred, the actual occupied area of ​​each internal structure in the fixed and pluggable parts is re-examined. The outermost position in each direction is determined and the overall occupied size is calculated. This is then compared with the space occupancy data before the functional structure transfer to obtain the boundary changes of the two parts in each direction. For example, before a faulty functional structure is moved, the space occupancy range in the length direction of the fixed part is 0-160mm, and after the move, it becomes 0-120mm. This indicates that the fixed part has reduced its space occupancy by 40mm in that direction. After the transfer to the pluggable part, the corresponding range of the pluggable part increases from 0-90mm to 0-130mm, indicating an increase of 40mm in space occupancy in that direction. By comparing the space ranges before and after the transfer, the free space created by the fixed part and the newly added space occupancy position of the pluggable part are obtained.

[0040] After determining the spatial change location, the empty area created by the removal of functional structures in the fixed section is reorganized. The internal structures surrounding the empty area are brought closer to that area according to their original arrangement, and their positions are adjusted in conjunction with the connection relationships of adjacent structures to avoid altering the original connection relationships due to the relocation. For example, if the removal of a faulty functional structure in the fixed section creates a 30mm empty length area, and there was originally a 10mm gap between the adjacent support structure and the terminal structure, the adjacent structures are moved towards the empty area to reduce the gap between the two structures, thus completing the relocation while maintaining the corresponding relationship of the connection ends.

[0041] Simultaneously, the fault-prone functional structures transferred to the pluggable section are rearranged, aligning their positions with the existing related internal structures in the pluggable section and adjusting their arrangement according to connection relationships. For cases where multiple transferred functional structures are located in different positions, functional structures with adjacent connections or interrelated maintenance operations are grouped together in the same area. For example, if two connection terminals in the pluggable section are located on opposite sides, and the transferred fault-prone functional structure needs to connect to both terminals, then this functional structure is moved between the two terminals to shorten the connection path and reduce the dispersed arrangement of internal structures. After the position adjustment, the arrangement range of each internal structure in the fixed and pluggable sections is redefined, consolidating the empty space created by the fixed section and centralizing the fault-prone functional structures in the pluggable section, thus obtaining a centralized functional structure.

[0042] Furthermore, based on the functionally centralized structure, the internal structures of the fixed and pluggable parts are rearranged, and adjustments are made to the pluggable connection positions and the connection structure between the fixed and pluggable parts to obtain a compact structure, specifically including: The connection ends of the fixed and pluggable parts in the functional centralized structure are identified, and the corresponding connection ends are matched according to the connection type to obtain the connection end correspondence. Based on the corresponding relationship between the connection ends, connect the corresponding connection ends and form a connection path according to the straight position relationship between the connection ends. Combine the signal isolation safety distance corresponding to the signal type transmitted by each connection path, check and correct the spacing between the connection paths, and obtain the connection path data corresponding to each connection end. The positional relationships of the connection path data are compared, and the connection paths with overlapping areas are identified as cross connection paths, thus obtaining the cross connection path data; Understandably, after the functional centralized structure is formed, the connection ends of each internal structure in the fixed and pluggable parts are first identified, and the corresponding connection end data is determined according to the actual connection positions between the internal structures. During processing, the actual connection positions are checked along the structural boundaries of each internal structure. When a certain position serves as an electrical connection, signal transmission, or structural connection between two internal structures, that position is identified as the connection end of the corresponding internal structure, and the location of the connection end, the connection type, and the corresponding internal structure are recorded. If there are multiple connection positions for the same internal structure, they are identified separately, so that different connection ends can be associated with their corresponding internal structures.

[0043] After the connection ends are identified, they are classified and matched according to the actual connection type used. When two connection ends have the same connection method and their structures can be interconnected, they are identified as corresponding connection ends. For multiple connection ends of the same type, they are distinguished based on the connection relationship and actual position of each connection end within its internal structure to avoid incorrectly connecting mismatched connection ends of the same type. This establishes a correspondence between the connection ends of the fixed and pluggable parts. For example, when the fixed and pluggable parts each have multiple connection ends of the same type, after classifying the types, the specific correspondence is further determined according to the connection position and adjacent internal structures.

[0044] After the correspondence between the connection ends is determined, each set of corresponding connection ends is connected according to the correspondence, and the straight line direction between the two connection ends is taken as the arrangement direction of the corresponding connection. The spatial position traversed between the connection ends is determined as the initial connection path corresponding to that set of connection ends. Other corresponding connection ends are processed in the same way, so that each set of corresponding connection ends between the fixed part and the pluggable part forms a corresponding connection path.

[0045] Different connection paths may transmit different signal types; therefore, signal isolation safety distances are determined according to the signal types corresponding to each connection path. The signal isolation safety distance represents the minimum spatial distance that must be maintained between different signal connection paths. Its value is determined according to the isolation requirements of the corresponding signal type and serves as a spacing limit when adjusting the position of the connection path. Subsequently, the actual distances between adjacent connection paths are compared. When the actual distance reaches the corresponding safety distance, the current path position remains unchanged; when the actual distance is less than the safety distance, the spatial positions of one or more connection paths are adjusted to meet the corresponding spacing requirements, while ensuring that the start and end positions of the connection paths are connected to their corresponding connection ends. This forms connection path data that meets the spacing requirements.

[0046] Subsequently, the adjusted connection paths are compared in terms of their positional relationships to check if they traverse the same areas. When two connection paths overlap in the same spatial location, or when parts of the path simultaneously occupy the same structural space, the corresponding area is identified as an overlapping area, and the connection path passing through this area is identified as a cross connection path. Connection paths that are only adjacent at the ends but do not occupy the same spatial area are not treated as cross connection paths. For example, when two sets of connection paths pass through the same internal area during the connection process, this shared area is marked as an overlapping area, and the two overlapping connection paths are recorded. After completing the path comparison, the connection paths with overlapping areas are extracted to form cross connection path data, providing a basis for subsequent processing to eliminate connection path overlaps by adjusting the positions of the corresponding internal structures.

[0047] Based on the cross-connection path data, the internal structures corresponding to the cross-connection paths are moved to ensure that the corresponding connection paths do not form overlapping areas, thus obtaining the rearranged internal structure position data. Based on the rearranged internal structure position data, the positions of the connection ends that are connected to the fixed part and the pluggable part are matched to obtain the connection end arrangement data. Based on the connection end arrangement data, the insertion and removal directions of the corresponding connection ends are analyzed, and the insertion and removal connection positions between the fixed part and the pluggable part are determined according to the insertion and removal directions. The connection structure corresponding to the insertion and removal connection positions is adjusted to obtain the connection structure adjustment data. Based on the connection structure adjustment data, the fixed part and the pluggable part are structurally combined to obtain a compact structure.

[0048] Specifically, after determining the cross-connection paths, first examine the internal structures at both ends of each cross-connection path, and determine the internal structures that need to be repositioned based on the overlapping areas of the paths. During processing, record the starting and ending connection ends and the overlapping areas of the cross-connection paths, and determine the internal structure of the fixed or pluggable part to which each connection end belongs. When multiple internal structures' connection paths simultaneously pass through the same overlapping area, prioritize the internal structure with relatively fewer connections and larger surrounding adjustment space as the moving object, while maintaining its main connection relationships with other internal structures unchanged.

[0049] After identifying the object to be moved, check its current position and the area occupied by surrounding structures, and adjust the position of the internal structure along the direction where there is available space. During the movement, simultaneously check the position changes of the corresponding connection ends and redetermine the connection paths between this internal structure and adjacent internal structures. When the connection paths that originally intersected no longer pass through the same spatial area, stop adjusting the position; if some paths still overlap, continue adjusting the corresponding internal structure or select another internal structure to move together, until there are no longer overlapping areas between the intersecting connection paths, and record the adjusted internal structure position and connection end position changes to form the rearranged internal structure position data.

[0050] For example, in a pluggable current transformer, the fixed part contains a fixed support structure and a primary conductive connection structure, while the pluggable part contains a winding assembly and a secondary wiring structure. The two sets of connection paths spatially overlap in the internal region between the fixed support structure and the winding assembly. If the fixed support structure has numerous fixed connections to other structures, and there is still usable space around the secondary wiring structure, the secondary wiring structure is moved and its position is adjusted away from the primary conductive connection structure. Simultaneously, the connection path between the secondary wiring structure and the winding assembly is redefined. When the two sets of connection paths no longer traverse the same spatial region, the adjusted position of the secondary wiring structure is retained. If path overlap still exists, the position of the secondary wiring structure is adjusted, or the position of the winding assembly is adjusted in conjunction with the adjustment, until the path overlap is eliminated.

[0051] After rearranging the internal structures, continue to examine the connection points that maintain the connection relationship between the fixed and pluggable parts, and align them according to the readjusted actual positions. During processing, read the positions of the corresponding connection points of the fixed and pluggable parts in the length, width, and height directions, and arrange the paired connection points according to the connection relationship, ensuring that each pair of corresponding connection points maintains its positional correspondence. When multiple connection points are distributed in the same area, distinguish them based on the arrangement order of their corresponding internal structures to avoid misalignment or overlapping connections.

[0052] For example, in the aforementioned pluggable current transformer, the fixed part is provided with a first primary connection terminal and a second primary connection terminal, while the pluggable part is provided with corresponding first pluggable connection terminals and second pluggable connection terminals. After rearrangement, the positions of each connection terminal in the length and width directions are read respectively. When the first primary connection terminal is located to the left of the second primary connection terminal, the first pluggable connection terminal is arranged to the left of the second pluggable connection terminal to keep the arrangement order of the two sets of connection terminals consistent. If misalignment occurs after rearrangement, the positions of the corresponding internal structures are adjusted to make the two sets of connection terminals correspond in position, and the arrangement order of the connection terminals, the spacing between adjacent connection terminals, and the corresponding relationship are recorded to form connection terminal arrangement data.

[0053] After determining the arrangement of the connection ends, the directions in which the fixed and pluggable parts can be relatively separated are analyzed, and the insertion / removal direction of the pluggable part is determined based on the arrangement of the corresponding connection ends. During processing, the direction in which the pluggable part can move is determined from the relative positions of the two parts, and the relative position changes of each corresponding connection end during movement are observed. When the pluggable part moves in a certain direction, if each corresponding connection end can gradually approach and complete the connection, or if separation is not obstructed by the surrounding internal structure, then that direction is determined as the insertion / removal direction. For cases with multiple possible directions of movement, the separation paths of the connection ends in each direction and the positions of the surrounding structures are compared, and the direction that maintains the correspondence of the connection ends and is not obstructed by the structure is selected as the insertion / removal direction.

[0054] For example, in a switchgear installation scenario, the fixed part is installed inside the cabinet, and the pluggable part is located in front of the fixed part, with two connecting ends on the fixed part facing the pluggable part. The movement of the pluggable part is simulated in the horizontal, vertical, and diagonal directions. When the pluggable part moves horizontally, both connecting ends can simultaneously approach their corresponding connecting ends without colliding with the fixed support structure or cabinet partitions. However, when moving vertically, it is restricted by the upper partition. Therefore, the horizontal direction is determined as the pluggable direction in this installation scenario.

[0055] After determining the insertion / removal direction, the areas where the corresponding connection ends between the fixed and pluggable parts are located are defined as the insertion / removal connection positions, and the connection structures corresponding to these positions are adjusted according to the determined insertion / removal direction. The connection structure is positioned between the fixed and pluggable parts, allowing the corresponding connection ends to connect or separate during insertion and removal. During adjustment, the installation position and arrangement direction of the connection structure are redefined based on the arrangement of each connection end, ensuring that the connection direction aligns with the movement direction of the pluggable part. When the connection structures obstruct each other or cannot simultaneously correspond to the connection ends during insertion / removal, the relative positions and adjacent spacing of the connection structures are adjusted so that each connection end can enter or leave its corresponding connection position.

[0056] For example, when two connecting ends on the fixed part are spaced horizontally apart, and two corresponding connecting ends on the pluggable part are also arranged horizontally, the two connecting structures are respectively placed between the corresponding connecting ends, and the connection direction is consistent with the horizontal insertion direction. If the distance between the two connecting structures is too small, causing one connecting structure to be interfered with by the other during insertion, then while keeping the corresponding relationship of the connecting ends unchanged, one of the connecting structures is moved perpendicular to the insertion direction, and the distance between the two connecting structures is redefined so that the two connecting structures can respectively connect with the corresponding connecting ends.

[0057] After adjusting the position and orientation of the connection structures, re-examine the connection relationship between the fixed and pluggable parts, confirming that each connection structure corresponds to its respective connection end. Record the installation position, connection direction, and adjacent arrangement of the adjusted connection structures to form connection structure adjustment data. Subsequently, based on the connection structure adjustment data, redetermine the relative installation positions of the fixed and pluggable parts, and move both parts to their corresponding combination positions, so that each adjusted connection structure is connected to its corresponding connection end.

[0058] After the fixed and pluggable parts are combined, the arrangement of the internal structures of the two parts and the connection positions between them are uniformly organized, so that the rearranged internal structure, the arrangement of the connection ends, and the adjusted connection structure form a continuous structural arrangement. When the fixed and pluggable parts remain combined, each corresponding connection end can be connected through the adjusted connection structure, and there is no longer any overlap between the connection paths. Then, the current combined structure is determined to be a compact structure, providing a structural basis for subsequent verification of the structural dimensions and connection dimensions of the fixed part, pluggable part, and connection structure during the insertion and removal process.

[0059] Furthermore, based on the compact structure, the structural dimensions between the fixed and pluggable parts, as well as the connection dimensions between them, are checked, and the compact structure is adjusted to obtain the target compact structure, specifically including: The dimensions of the fixed part, the pluggable part, and the connection structure between them in the compact structure are extracted to obtain the structural dimensions of the fixed part, the structural dimensions of the pluggable part, and the connection dimensions. Based on the connection position and connection size between the fixed part and the pluggable part, the range of movement of the pluggable part along the insertion and removal direction is determined, and the range of movement is divided into multiple insertion and removal positions. Based on multiple insertion and removal positions, the structural spacing between the fixed part and the pluggable part and the change in connection dimensions between the connecting structures are calculated at each insertion and removal position to obtain the spacing data and the change in connection dimensions during the insertion and removal process. By comparing the spacing data and connection dimension change data during the insertion and removal process, the insertion and removal positions where structural interference occurs between the fixed part and the pluggable part, as well as the insertion and removal positions where the connection dimensions do not meet the connection requirements, are determined as the dimension interference positions. Understandably, after the compact structure is formed, the dimensions of the fixed part, the pluggable part, and the connecting structure between the two parts are first read. During processing, the structural outlines of the fixed part and the pluggable part are determined separately, and the distances between their outermost boundaries are extracted along the length, width, and height directions to obtain the structural dimensions of the fixed part and the pluggable part. For the connecting structure, the positions where the connections are formed are examined, and the length, width, height, and spacing between adjacent connection positions of the connecting structure are extracted. The relative positional relationship between the connecting structure and the fixed and pluggable parts is recorded.

[0060] The dimensions of the fixed part represent the actual space occupied by the fixed part in its assembled state. The dimensions of the pluggable part represent the structural range formed when the pluggable part moves to different pluggable positions. The connection dimensions represent the dimensional relationships required between the connection positions of the connection structure in the connected state. For cases with multiple connection structures, the dimensions of each connection structure are extracted and recorded according to the correspondence between the connection ends. For example, when multiple connection structures arranged in the same direction are set between the fixed part and the pluggable part, in addition to extracting the outer dimensions of each connection structure itself, the center distance between adjacent connection structures and the relative distance between each connection structure and its corresponding connection end are also recorded to reflect changes in local connection positions.

[0061] After determining the dimensions of each part, the path for the pluggable part to move from the connected state to the fully separated state is determined according to the insertion and removal direction defined in the compact structure. The fixed part is held in its current position, and the starting point of the movement is determined along the insertion and removal direction, using the position of the pluggable part in its initial connected position as the starting point. When the corresponding connection ends are completely separated and the pluggable part is no longer connected to the fixed part, the distance between the starting and ending positions is determined as the movement range of the pluggable part.

[0062] Once the movement range is determined, it is divided into multiple consecutive position intervals according to the insertion and removal direction. Within each interval, a corresponding position is selected as the insertion and removal position. Starting from the initial connection position, these positions are arranged sequentially along the insertion and removal direction, so that each position reflects the different structural states of the pluggable part, from complete connection to gradual separation and finally complete detachment. The insertion and removal positions can be evenly divided according to the movement range or based on the dimensional changes of the connected structures. When the relative distance between connected structures changes rapidly within a certain area, additional insertion and removal positions are added to that area to refine the recording of dimensional changes.

[0063] After multiple insertion / removal positions are established, the pluggable portion is moved sequentially to each position. The nearest structural boundary between the fixed portion and the pluggable portion is then observed, and the minimum distance between the two structural boundaries is calculated as the structural spacing corresponding to the current insertion / removal position. In cases where multiple adjacent structural regions exist, the structural spacing between each adjacent region is calculated, and the minimum structural spacing is used as reference data to determine whether structural interference exists at the current insertion / removal position.

[0064] Simultaneously, the relative positions of each connecting structure after the pluggable part is moved are recalculated. The spacing, alignment, and relative offset of the corresponding connecting ends during the movement are examined and compared with the connection dimensions recorded in the initial connection state to obtain the connection dimension changes corresponding to each plugging / unplugging position. For connecting structures that need to maintain mutual correspondence, the lateral offset, longitudinal spacing, and positional changes in the plugging / unplugging direction between the connecting ends are recorded after movement. The structural spacing corresponding to each plugging / unplugging position is summarized according to the plugging / unplugging sequence to form plugging / unplugging process spacing data. Simultaneously, the connection dimension changes at each position are recorded to form connection dimension change data. For example, when the pluggable part gradually moves outward from the initial connection position along the plugging / unplugging direction, the initial connection position, intermediate movement position, and completely separated position can be set sequentially. The structural boundary spacing and the separation state of the connecting structures are then examined to obtain continuous dimension change data from the connection state to the separation state.

[0065] After the data on spacing and connection dimension changes during the insertion and removal process are generated, the data corresponding to each insertion and removal position are compared to check whether the minimum structural spacing between the fixed part and the pluggable part is less than zero or whether the two structural boundaries spatially overlap. When the two structural boundaries overlap at the same insertion and removal position, or when the structural range of the pluggable part enters the structural occupancy range of the fixed part, the insertion and removal position is determined as the location of structural interference; for cases where the structural spacing is small but the two structures still maintain independent space, the corresponding structural spacing data is retained.

[0066] Subsequently, the changes in connection dimensions between the connection structures at each insertion and removal position were examined, and a judgment was made based on the positional relationships required for the connection to form a connection. When the relative spacing, alignment, or offset range between the corresponding connection ends exceeds the allowable connection range of the connection structure, causing the connection ends to be unable to complete insertion, connection, or separation in their original positions, the insertion and removal position is determined as a position where the connection dimensions do not meet the connection requirements. The connection requirements are determined based on the dimensions of the connection structure itself and the dimensional range required for the connection ends to form a stable connection. That is, the relative dimensions of each connection end in the normal connection state are recorded when the compact structure is formed, and the allowable dimensional change range is determined by combining the allowable movement range of the connection ends during insertion and removal.

[0067] After determining the structural spacing and connection dimensions, the insertion / removal locations where structural interference occurs and those where connection dimensions do not meet the requirements are summarized. If the same insertion / removal location has both overlapping structural boundaries and abnormal connection dimensions, it is recorded as the same location requiring adjustment. If different insertion / removal locations exhibit the same problem, the corresponding location and problem type are retained separately, forming a dimensional interference location. By continuously checking different insertion / removal locations within the entire movement range, the specific locations where structural interference or abnormal connection dimensions occur during the actual insertion / removal process of the compact structure are determined, providing a locational basis for subsequent identification of structural locations requiring adjustment and dimensional adjustments.

[0068] Based on the dimensional interference position, extract the structural boundaries of the fixed part and the pluggable part and the dimensional boundaries of the connecting structure at the corresponding insertion and removal position, identify the structural boundaries where structural interference and connection dimensional abnormalities occur, and obtain the position of the structure to be adjusted. Based on the location of the structure to be adjusted, the corresponding structural interference dimensions and the dimensional deviations of the connecting structures are calculated. The corresponding structural outline dimensions and connecting dimensions are then adjusted according to the structural interference dimensions and dimensional deviations to obtain the adjusted structural dimension data. Based on the adjusted structural dimensions, the fixed parts, pluggable parts, and connecting structures are updated, and the structural and connecting dimensions are checked to obtain the target compact structure.

[0069] Specifically, after determining the dimensional interference positions, the actual spatial range of the fixed part, pluggable part, and connecting structure is redefined according to the corresponding insertion and removal positions. The pluggable part is moved to the corresponding position, and the outermost structural contours of the fixed part and pluggable part are read to form the structural boundary. For the connecting structure, the position of the connecting end where the connection dimension is abnormal and the dimensional range of the connecting structure are read to form the dimensional boundary of the connecting structure. Subsequently, the positions of each structural boundary are matched to determine the specific areas where spatial overlap, insufficient spacing, and connection dimension abnormalities occur, and the positions of the structures to be adjusted are formed according to their respective structural records.

[0070] During the specific identification process, the structural boundaries of the fixed and pluggable parts are examined along the insertion / removal direction. When the two structural boundaries intersect, contact each other, or fail to maintain a normal structural spacing, the corresponding area is marked as a structural interference area. For connecting structures, areas with abnormal connection dimensions are determined based on the relative distance between the connecting ends, their alignment, and the connection direction. For insertion / removal positions where both structural interference and abnormal connection dimensions exist, the structural areas corresponding to the two types of abnormalities are associated, allowing subsequent adjustments to consider the mutual influence between the structural outline and the connection position. For example, when the pluggable part moves to a certain intermediate insertion / removal position, its side structural outline overlaps with the adjacent internal structure of the fixed part by 5mm; the overlapping structural boundary area is then identified as the structural position to be adjusted. When the actual distance between a connecting end and its corresponding connecting end is 8mm, while the minimum required connection distance is 10mm, the connecting end and its corresponding connecting structure are identified as the structural position to be adjusted.

[0071] After determining the location of the structure to be adjusted, the structural interference dimensions and connection dimension deviations are calculated. For areas where structural boundaries overlap, the maximum dimension of the overlapping area in the corresponding direction is calculated. For areas where there is no overlap but the spacing is insufficient, the difference between the actual spacing and the required structural spacing is calculated, and the resulting value is taken as the structural interference dimension. For example, if the fixed part sidewall structure and the pluggable part side structure overlap by 5mm in the width direction, then 5mm is determined as the structural interference dimension; if the actual spacing is 3mm, and the minimum structural spacing to be maintained is 5mm, then 2mm is taken as the structural interference dimension to be eliminated. For abnormal connection dimensions, the connection end spacing, positional offset, and connection structure dimensions at the current pluggable position are compared with the dimension range corresponding to the normal connection state, and the difference between the actual dimension and the allowable range is calculated to form the dimension deviation.

[0072] After determining the structural interference dimensions and dimensional deviations, the corresponding structural outlines and connection dimensions are adjusted. For structural interference areas, the outward extension dimensions of the corresponding structural boundary are reduced according to the structural interference dimensions, or the structural boundary is moved away from the interference area. For areas with abnormal connection dimensions, the relative distance between the connection ends, the installation position of the connection structure, or the dimensions of the connection structure itself are adjusted according to the dimensional deviations to bring the adjusted dimensions back into the required range. When two types of abnormalities exist at the same location, the structural outline that has a greater impact on the overall space occupation is adjusted first, and then the position and dimensions of the connection structure are corrected to avoid the connection structure re-entering the interference area after adjustment. During the adjustment process, the original connection relationships are maintained, and the adjustment results of the fixed parts, pluggable parts, and connection structures are recorded separately to form the adjusted structural dimension data.

[0073] After obtaining the adjusted structural dimensions, the original dimensional parameters are replaced with the adjusted ones, and the structural boundaries and internal structural arrangement of the fixed and pluggable parts are redefined. Simultaneously, the installation positions of the connecting structures and the relative positions of the connecting ends are updated. Subsequently, the parts are recombined according to the original connection relationships, so that the adjusted structural boundaries, internal structures, and connecting structures form a new structural relationship, resulting in the adjusted compact structure.

[0074] After the adjusted compact structure is formed, the structural dimensional relationship between the fixed part and the pluggable part is re-examined along the insertion and removal direction, and the changes in connection dimensions of each connection structure under different connection states and insertion and removal positions are reviewed. The insertion and removal positions of the pluggable part within the range of movement are redefined, and each connection between the fixed part and the pluggable part is checked to see if there is still overlap of structural boundaries, insufficient spatial spacing, or abnormal connection dimensions. The verification results are then compared with the dimensional interference positions before adjustment to confirm whether the original abnormalities have been eliminated.

[0075] Subsequently, the actual dimensions of each connection end and connection structure are verified. When there is no structural interference between the fixed part and the pluggable part at each insertion and removal position, and each connection structure meets the connection requirements during the corresponding insertion and removal process, the current adjusted structural state is determined as the target compact structure; if there are still structural interference positions or abnormal connection dimensions, the position of the structure to be adjusted is re-determined, and the size adjustment and structural update are continued in the aforementioned manner until all structural dimensions and connection dimensions are verified.

[0076] Furthermore, based on the target compact structure, the installation position relationship between the fixed part and the pluggable part is determined. Combined with the installation methods corresponding to different installation scenarios, the compact design results for the pluggable current transformer under different installation scenarios are obtained, specifically including: The mounting surfaces and connection positions of the fixed and pluggable parts in the target compact structure are identified, the relative positions of the fixed and pluggable parts are determined, and the mounting position relationship is obtained. Based on the installation location relationship, the installation space direction corresponding to different installation scenarios is identified, and the installation location relationship is matched with the installation space direction to obtain the installation matching data corresponding to each installation scenario; Based on the installation matching data, the mounting surface orientation of the fixed part and the insertion / removal direction of the pluggable part are adjusted to the installation space direction of the corresponding installation scenario to obtain the installation direction data corresponding to each installation scenario. Based on the installation direction data, determine the range of movement of the pluggable part along the pluggable direction, and compare the range of movement with the available space in the corresponding installation scenario to obtain the pluggable space adaptation result. Based on the adaptation results of the pluggable space, the relative installation position between the fixed part and the pluggable part is adjusted to obtain the installation position adjustment data corresponding to each installation scenario; Based on the installation location adjustment data and the installation methods corresponding to each installation scenario, the installation structure of the fixed part and the pluggable part is combined to obtain the compact design results of the pluggable current transformer under different installation scenarios.

[0077] Specifically, after determining the target compact structure, the installation structures of the fixed and pluggable parts are identified separately, and the structural relationships between the two parts and their external installation positions and interconnections are examined. Along the outer structure of the fixed part, structural surfaces that can be fixed to the mounting carrier are identified. Surfaces with mounting holes, mounting grooves, positioning structures, or other fixing structures are designated as the mounting surfaces of the fixed part, and their spatial position, orientation, and corresponding installation structures are recorded. Simultaneously, the areas connecting the fixed and pluggable parts are examined, and the positions of each connection end and connection structure are recorded. Subsequently, the same process is applied to the pluggable part, identifying its connection positions to the fixed part and the structural direction of movement during insertion and removal. The arrangement order and spatial coordinates of each connection position are recorded, forming installation structure data for both the fixed and pluggable parts. For example, if the bottom of the fixed part has two mounting holes for fixing to the cabinet mounting bracket, the corresponding surface is designated as the mounting surface, and the distance between the two mounting holes and their position relative to the outer contour of the fixed part are recorded.

[0078] After the installation structure data for both parts are generated, the mounting surfaces of the fixed part and the connection positions of the pluggable part are mapped to each other, and the relative installation relationship is determined according to the actual structural positions of the two parts in their normal combined state. Using the mounting surface of the fixed part as a positional reference, the direction and distance of the pluggable part's connection position relative to the mounting surface of the fixed part are read. Then, the corresponding connection positions in the fixed part are mapped one-to-one with the connection positions in the pluggable part to determine the mounting side of the pluggable part relative to the fixed part and the direction of insertion / removal. For cases with multiple mounting surfaces or multiple connection positions, the corresponding relationships are recorded separately. For example, if the mounting surface of the fixed part is located inside the lower part of the switch cabinet, the two connection ends are located 50mm above the mounting surface, and the corresponding connection end on the pluggable part is located outside the connection end of the fixed part, then the pluggable part is determined to be inserted horizontally from the outside of the cabinet towards the fixed part, and this horizontal direction is defined as the relative installation direction.

[0079] After clarifying the installation location relationships, continue to examine the actual installation space in different installation scenarios, and determine the corresponding installation space direction for each scenario based on the installation carrier, opening location, and the extension direction of available space. Examine the direction of the fixed installation location and the surrounding structural boundaries within the installation space. When a certain direction has continuous available space and can meet the movement requirements of the pluggable parts, determine that direction as the installation space direction for the corresponding installation scenario. For example, if there is a 300mm continuous opening space on the front of the switch cabinet, while the space on the top and sides of the cabinet is smaller, then the horizontal direction of the opening is determined as the primary installation space direction; if in another installation scenario, the side of the switch cabinet has a continuous 250mm available space, then the lateral horizontal direction is determined as the corresponding installation space direction.

[0080] Subsequently, the established installation position relationship between the fixed and pluggable parts is mapped to the installation space orientation in different installation scenarios to check whether the orientation of the fixed part's mounting surface and the insertion / removal direction of the pluggable part are consistent with the corresponding installation space. When the current installation position relationship is consistent with the installation space orientation, the relative orientation between the two parts is retained; when the mounting surface orientation or insertion / removal direction is inconsistent with the installation space orientation, the structural position and adjustment direction that need to be adjusted are determined. For scenarios where the installation space orientation changes, the overall orientation of the fixed and pluggable parts is adjusted so that the mounting surface of the fixed part faces the corresponding installation carrier, and the insertion / removal direction of the pluggable part is consistent with the direction allowed to move in the installation space, while maintaining the original connection end correspondence between the two parts, thus forming installation direction data corresponding to each installation scenario. For example, the original design of the compact structure was that the fixed part was mounted with its mounting surface facing down and the pluggable part was plugged in and out horizontally. When installed in a switch cabinet with limited lateral space, the overall structure was adjusted 90° around the corresponding mounting axis so that the mounting surface of the fixed part faced the side of the cabinet and the pluggable part was adjusted to be plugged in and out vertically. Then, it was checked whether the connection ends on the two parts could still correspond to each other.

[0081] After adjusting the installation direction, determine the range of movement required for the pluggable part to move from the connected state to the fully disconnected state, and determine the area occupied by this range in the actual installation space according to the plugging / unplugging direction in the corresponding installation scenario. Starting from the initial connected position of the pluggable part, extend along the determined plugging / unplugging direction to the fully disconnected position, and define the distance between the starting position and the ending position as the pluggable / unplugging movement range. Check whether there are any limiting structures such as mounting brackets, shell boundaries, or adjacent equipment within this range. For example, if the pluggable part needs to move 120mm along the plugging / unplugging direction to move from the fully inserted position to the fully disconnected position, then the pluggable / unplugging movement range is defined as the distance from the initial position to the position after moving 120mm, and check whether there are any cabinet side panels or mounting brackets within this range.

[0082] The movement range of the pluggable part is compared with the available space in the corresponding installation scenario. When the available space can completely cover the space traversed by the pluggable part from the initial connection position to the fully separated position, the current installation direction is determined to meet the pluggable space requirements. When the available space is less than the required movement range, or there is an obstructing structure within the movement range, the current installation direction is determined to not meet the pluggable space requirements. For cases of insufficient local space, the location and direction of the insufficient space are recorded to form the pluggable space adaptation result. For example, if the pluggable part requires a movement distance of 120mm to completely detach from the fixed part, but a certain installation scenario only has 100mm of continuous available space along the pluggable direction, then the installation scenario is determined to have a 20mm space deficiency. If there is also a mounting bracket protruding 10mm inward within this range, the location and direction of the mounting bracket are recorded simultaneously.

[0083] After the insertion / removal space adaptation result is obtained, the relative installation positions between the fixed and pluggable parts are further adjusted for installation scenarios with insufficient space or obstructed movement. Based on the location of insufficient space, the possible adjustment directions between the two parts are determined, while maintaining the connection between the mounting surface of the fixed part and the corresponding mounting carrier. The connection position of the pluggable part is moved towards the side with more available space, or the relative orientation between the fixed and pluggable parts is adjusted so that the movement range of the pluggable part avoids the restrictive structure. After each position adjustment, the movement range of the pluggable part is re-determined and compared again with the available space in the installation scenario until the movement range falls within continuous available space. For example, if the pluggable part requires a 120mm movement distance to completely separate, but there is a mounting bracket behind it resulting in only 100mm of actual space, the pluggable part is moved 15mm away from the mounting bracket relative to the fixed part, and the insertion / removal movement range is recalculated. If the adjusted movement range falls entirely within the available space, the position adjustment result is retained.

[0084] For installation scenarios where the insertion and removal space already meets the requirements, the relative installation positions between the fixed part and the pluggable part remain unchanged, and the corresponding positional relationship is recorded. For structures that meet the insertion and removal space requirements after position adjustment, the adjusted mounting surface position, pluggable part connection position, and insertion / removal direction are recorded to form installation position adjustment data corresponding to each installation scenario.

[0085] After adjusting the installation positions for each installation scenario, the fixed and pluggable parts are structurally combined according to the installation method used in that scenario. Based on the actual orientation and installation position of the mounting surface in different installation scenarios, the fixed part is placed in the corresponding installation position. Then, the combination position of the pluggable part relative to the fixed part is determined according to the installation position adjustment data, ensuring that the connection structure between the two parts corresponds to the insertion / removal direction. When different installation methods are used, only the fixed position between the overall structure and the installation space is adjusted, while maintaining the established connection relationship between the fixed and pluggable parts. For example, in one installation scenario using a bottom-mounted method, the fixed part is bolted to the cabinet bracket through the bottom mounting holes; in another installation scenario using a side-mounted method, the mounting structure on the side of the fixed part corresponds to the side mounting bracket of the cabinet, and the pluggable part is arranged according to the determined insertion / removal direction.

[0086] After assembling the fixed and pluggable parts, retain the mounting surface orientation of the fixed part, the insertion and removal direction of the pluggable part, the relative installation positions of the two parts, and the corresponding installation methods for different installation scenarios. Re-examine the insertion and removal process of the pluggable part in the actual space after installation. During inspection, move the pluggable part from a fully connected position to a fully separated position to check for interference with the mounting carrier, mounting bracket, or surrounding structures during the movement. Simultaneously, confirm that each connection structure can complete the connection and separation according to the corresponding relationship.

[0087] If structural installation can be completed in all installation scenarios, and the pluggable part can be inserted and removed when moving in a defined direction, then the corresponding structural state is determined as the compact design result for each installation scenario. If any installation scenario still has insufficient space, structural obstruction, or mismatched connection positions, then the limiting positions of that scenario are redefined, and the relative installation positions of the fixed part and the pluggable part are adjusted until the installation space and pluggable process verification for all installation scenarios are completed. For example, in the first installation scenario, the fixed part adopts a bottom installation method, and the pluggable part moves horizontally with a continuous pluggable space of more than 120mm; in the second installation scenario, the fixed part adopts a side installation method, and the pluggable part moves vertically with a continuous pluggable space of 130mm. The installation surface, installation position, and pluggable direction corresponding to the two installation scenarios are retained respectively, forming a compact design result that adapts to different installation spaces.

[0088] Furthermore, a compact design system for pluggable current transformers adapted to multiple scenarios is proposed to achieve the compact design method for pluggable current transformers as described above, including: The installation scenario module is used to obtain multiple installation scenarios corresponding to pluggable current transformers.

The plug-in / plug-out adjustment module is used to determine multiple plug-in / plug-out positions of the pluggable parts along the plug-in / plug-out direction according to the compact structure, calculate the changes in structural spacing and connection dimensions at each plug-in / plug-out position, and adjust the structural outline dimensions and connection dimensions according to the dimensional interference position to obtain the target compact structure. The installation adapter module is used to determine the installation position relationship between the fixed part and the pluggable part according to the target compact structure. The installation position is adjusted and the installation structure is combined according to the installation space direction and installation method corresponding to different installation scenarios, so as to obtain the compact design results of the pluggable current transformer under different installation scenarios.

The structural assembly unit is used to combine the fixed and pluggable parts of the compressed structure, and to check the dimensions of the combined structure against the structural dimension constraints. The structural positions that do not meet the structural dimension constraints are corrected to obtain the initial compact structure.

[0090] Furthermore, the functional modules include: The internal structure partitioning unit is used to partition the fixed part in the initial compact structure into internal structures and extract the connection ends of each internal structure unit to obtain the connection end data corresponding to each internal structure unit.

A functional structure centralization unit is used to detach easily malfunctioning detachable functional structures from the fixed part and transfer them to the pluggable part. The empty space in the fixed part is gathered according to the spatial changes after the transfer, and the transferred functional structures are centrally arranged to obtain a functional centralization structure.

[0091] Furthermore, the plug-in adjustment module includes: The dimension extraction unit is used to extract the dimensions of the fixed part, the pluggable part and the connection structure between them in the compact structure, and obtain the structural dimensions of the fixed part, the structural dimensions of the pluggable part and the connection dimensions.
