Description

Technical Field

[0001] This disclosure relates to the field of filtering equipment technology, and specifically to a static var generator that is easy to automate. Background Technology

[0002] In the power system field, SVG (Static Var Generator) is the core device for dynamic reactive power compensation. It typically adopts a multi-layer cascaded power module architecture design, which realizes topology functions through the layered arrangement of multiple circuit boards. In high-voltage and high-capacity scenarios, such devices need to meet complex circuit interconnection requirements. However, the traditional multi-layer cascaded structure has problems such as cumbersome assembly processes and low accuracy of manual positioning, resulting in low assembly efficiency of automated production lines. Moreover, interference in inter-layer signal transmission can easily cause control delays. Its production process involves multiple inefficient processes such as manual welding and layer alignment calibration.

[0003] In related technologies, to improve modularity, some SVG devices distribute functional components across different circuit boards, using connectors to achieve interlayer electrical connections. While this structure facilitates independent debugging of individual functional modules, the parallel or staggered arrangement of adjacent circuit boards can easily lead to assembly space conflicts. Furthermore, the lack of standardized assembly benchmarks within traditional housings makes it difficult for automated equipment to achieve precise gripping and positioning. Especially during large-scale mass production, deviations in component positions and differences in connection methods result in poor product consistency and high rework rates.

[0004] The multi-layered cascaded structure and non-standardized assembly design of existing SVG equipment result in poor adaptability to automated processing. On the one hand, the manual-driven circuit board alignment and soldering processes are difficult to meet the efficiency requirements of large-scale production. On the other hand, the lack of a unified benchmark for the layout of functional components on different circuit boards easily leads to signal crosstalk and structural interference, reducing the reliability of equipment operation. Especially with the demand for miniaturization and high consistency of SVG equipment in new energy power plants, the contradiction between the traditional multi-layered distributed structure and automated production is becoming increasingly prominent, urgently requiring an integrated structural design that facilitates automated processing. Summary of the Invention

[0005] The main objective of this disclosure is to provide a static var generator that is easy to automate, in order to solve the problems of cumbersome assembly processes, low accuracy of manual positioning, and poor adaptability to automated processing caused by multi-layer cascaded structures in related technologies.

[0006] To achieve the above objectives, this disclosure provides a static var generator that is easy to automate, comprising: The housing has an assembly cavity, and an assembly wall is provided inside the assembly cavity; At least two circuit boards are mounted on the mounting wall. Adjacent circuit boards are spaced apart or staggered. Different functional components are provided on different circuit boards. At least some circuit boards are electrically connected to each other. During the assembly of the static var generator, at least two circuit boards are assembled in the same process.

[0007] Specifically, the housing provides support and protection for the entire static var generator, while the mounting cavity provides a stable mounting space for the circuit boards. The mounting walls, located within the mounting cavity, provide precise positioning references for the circuit board installation. As functional components of the static var generator, at least two circuit boards can be installed, each mounted on the mounting walls. These circuit boards are spaced apart or staggered, ensuring both electrical isolation between them and a compact structural layout.

[0008] Different functional components are installed on different circuit boards, and these components work together to achieve the various performance indicators of the static var generator. At least some circuit boards are electrically connected to achieve signal transmission and interaction, ensuring the stable flow of signals inside the static var generator.

[0009] During the assembly of the static var generator, at least two circuit boards are assembled in the same process, which greatly improves production efficiency and reduces production costs.

[0010] By assembling multiple circuit boards in the same process, the production process is simplified, manual intervention and assembly time are reduced, and the consistency and reliability of the assembly are improved.

[0011] In some examples, the mounting wall is the bottom wall of the mounting cavity, and at least two circuit boards are included: The first circuit board is detachably connected to the bottom wall; The second circuit board is detachably connected to the bottom wall and the connection position is spaced apart from the second circuit board; The third circuit board is detachably connected to the bottom wall, either directly or indirectly, and is at least partially located between the first and second circuit boards.

[0012] This layout makes full use of the space within the assembly cavity, resulting in a more compact and orderly arrangement of the circuit boards. The first and second circuit boards can be arranged parallel to each other on the bottom wall, with sufficient electrical isolation between them ensured by spacing, preventing signal interference. The third circuit board is at least partially located between the first and second circuit boards. This staggered arrangement not only further improves space utilization but may also help optimize the electrical performance of the static var generator, such as reducing signal transmission paths and improving signal processing efficiency.

[0013] In some examples, the first circuit board is mounted in the region of the assembly cavity near the first side, the second circuit board is mounted in the region of the assembly cavity near the second side, and the third circuit board is mounted in the central region of the assembly cavity.

[0014] This disclosure mounts the first circuit board in the region of the assembly cavity near the first side and the second circuit board in the region of the second side, so that the two circuit boards are spatially separated from each other, effectively avoiding possible signal interference between them and ensuring the stable operation of their respective functional components.

[0015] In some examples, both the first and second circuit boards are fixedly connected to the bottom wall by fasteners, and the two sides of the third circuit board are respectively connected to the first and second circuit boards.

[0016] The first and second circuit boards of this disclosure are fixedly connected to the bottom wall by fasteners, such as screws and bolts. This connection method can provide stable support for the circuit boards and ensure that they will not be displaced due to vibration or other reasons during the operation of the static var generator, thereby ensuring the stable operation of the functional components on the circuit boards and maintaining the consistency of the performance parameters of the static var generator.

[0017] In some examples, the two sides of the third circuit board are connected to the first and second circuit boards respectively by fasteners, and the connection points are spaced to increase the assembly spacing.

[0018] This design plays a significant role in ensuring the performance and stability of the static var generator.

[0019] The fastener connection ensures a secure connection between the third circuit board and the first and second circuit boards. Even when subjected to external factors such as vibration during the operation of the static var generator, it will not easily loosen or fall off, thus maintaining a stable electrical connection between the circuit boards and ensuring smooth signal transmission.

[0020] The addition of isolators at the connection points to increase assembly spacing can effectively achieve electrical isolation between circuit boards, prevent signals on different circuit boards from interfering with each other, and ensure the accuracy and purity of signal processing by the static var generator.

[0021] In some examples, the first circuit board is a capacitor circuit board, the second circuit board is a filter circuit board, and the third circuit board is an inverter circuit board, with the inverter circuit board positioned higher than the other two circuit boards.

[0022] This disclosure designs the first circuit board as a capacitor circuit board, whose core function is to provide stable and accurate capacitance parameters for the entire static var generator system, ensuring effective storage and release of electrical energy during signal processing and maintaining stable circuit operation. The capacitor circuit board can integrate various capacitor components of different specifications and capacitance values ​​as needed. These components are laid out and matched according to the required parameters to meet the operating requirements of the static var generator under different frequencies and signal strengths.

[0023] The second circuit board is a filter circuit board, which performs filtering on the input signal. Through a series of carefully designed filter circuits, such as low-pass filtering, high-pass filtering, and band-pass filtering, noise and interference components in the signal can be effectively removed, extracting the desired clean signal. The component layout and circuit design on the filter circuit board have been rigorously optimized to ensure efficient filtering under different operating environments, improving signal quality and reliability.

[0024] The third circuit board is set as an inverter circuit board, which can convert direct current to alternating current, or change the frequency, phase, and other parameters of alternating current. The inverter circuit board plays the role of signal conversion and amplification in the static var generator system, and can further process and enhance the filtered signal to meet the requirements of subsequent equipment or systems.

[0025] In some examples, the capacitor circuit board is provided with multiple capacitor structures and a fan mounting plate. The capacitor structures are used to provide electrical power, and the fan mounting plate is used to fix the fan. The inverter circuit board is equipped with a heat sink, which is compatible with the fan. The fan can drive airflow through the heat sink and complete the heat dissipation. The filter circuit board has multiple staggered parallel magnetic rings.

[0026] The capacitor circuit board contains multiple capacitor structures, which are electronic components for the storage and release of electrical energy in the static var generator (SVR). These capacitor structures can quickly store and release electrical energy according to the operating requirements of the SVR, providing reliable power support for the stable operation of the SVR.

[0027] The installation of the fan mounting plate provides a fixed foundation for the subsequent installation of the fan. As an important component of the heat dissipation system, the stability of the fan installation directly affects the heat dissipation effect.

[0028] By accurately fixing the fan to the capacitor circuit board using the fan mounting plate, it is possible to ensure stable operation of the fan during operation and provide continuous and effective heat dissipation for the static var generator.

[0029] The heatsink on the inverter circuit board is matched with the fan, and this design is the core of the cooling system. The heatsink is usually made of materials with good thermal conductivity, which can quickly conduct away the heat generated by the inverter circuit board during operation. The fan drives airflow through the heatsink, accelerating heat dissipation and forming an efficient cooling cycle. The interlaced parallel connection of multiple magnetic rings enhances the filtering effect and expands the filtering frequency band.

[0030] In some examples, the housing includes a bottom shell, a front panel, a rear panel, and a cover plate. The bottom shell is a U-shaped plate with a top opening and two side openings. The front panel and the rear panel are detachably connected to the two side openings, and the cover plate is detachably connected to the top opening. At least two of the bottom shell, front panel, rear panel, and cover plate have ventilation holes. Multiple connecting posts are located on the bottom shell corresponding to the bottom wall. The first, second, and third circuit boards are connected to the bottom shell via these connecting posts, which also increase the assembly clearance (improving heat dissipation). At least two of the bottom shell, front panel, rear panel, and cover plate have heat dissipation holes, forming a multi-directional heat dissipation channel. When the static var generator is working, the heat generated by the internal circuit board can be fully exchanged with the outside air through these heat dissipation holes.

[0031] For example, hot air can be exhausted from the heat dissipation holes on the bottom shell, while cooler outside air can enter from the heat dissipation holes on the front or rear panel, forming convection, accelerating heat dissipation, effectively reducing the internal temperature of the static var generator, and ensuring that each circuit board works stably in a suitable temperature environment.

[0032] The multiple connecting posts located on the bottom wall of the base shell not only connect the circuit boards but also play a crucial role in improving heat dissipation. The first, second, and third circuit boards are connected to the base shell via these connecting posts, creating a certain assembly gap between the circuit boards and the base shell. This gap allows for airflow, enabling air to move freely between the circuit boards and the base shell and carry away the heat generated by the circuit boards.

[0033] In some examples, the base includes a mounting base plate and protective side plates disposed on both sides of the mounting base plate, with at least two circuit boards directly or indirectly mounted on the mounting base plate.

[0034] The mounting base provides a stable foundation platform for the installation of the circuit board. Its flat surface and appropriate size design ensure the flatness and stability of the circuit board during installation.

[0035] During installation, the circuit board can be securely fixed to the mounting base plate using various connection methods, such as the aforementioned fasteners and fixtures, to prevent displacement due to vibration or other reasons during operation, thereby ensuring the stability of the static var generator's performance. The protective side plates located on both sides of the mounting base plate provide multifaceted protection.

[0036] In some examples, the multiple connecting posts include a first connecting post for connecting a first circuit board, a second connecting post for connecting a second circuit board, and a third connecting post for connecting a third circuit board; Alternatively, the multiple connecting posts include a first connecting post for connecting a first circuit board, a second connecting post for connecting a second circuit board, and a third circuit board staggered above the first and second circuit boards, with isolation components for connecting to the third circuit board respectively provided on the first and second circuit boards.

[0037] When a design with multiple connecting posts is used, including a first connecting post for connecting a first circuit board, a second connecting post for connecting a second circuit board, and a third connecting post for connecting a third circuit board, each circuit board has a dedicated corresponding connecting post for connection. This one-to-one correspondence makes the connection more precise and reliable.

[0038] If a design is adopted that uses multiple connecting posts, including a first connecting post for connecting a first circuit board and a second connecting post for connecting a second circuit board, and a third circuit board is staggered above the first and second circuit boards, and the first and second circuit boards are respectively provided with isolation components for connecting to the third circuit board, then this design has unique advantages.

[0039] In the filter static var generator provided in this embodiment, which is easy to automate, at least two circuit boards are assembled in the same process. By distributing different functional components on circuit boards that are spaced apart or staggered and making electrical connections, the production process is simplified. This achieves the technical effects of reducing manual intervention, shortening assembly time, and improving assembly consistency and reliability. It also solves the technical problems of low production efficiency, high labor costs and large assembly errors caused by traditional step-by-step assembly processes. Attached Figure Description

[0049] This disclosed static var generator (SVA) is a specialized device for dynamic reactive power compensation in power systems, primarily used to achieve rapid reactive power regulation and stable grid voltage control. It provides an efficient and reliable reactive power support solution for scenarios such as new energy grid integration and high-voltage transmission. The SVA adopts a modular integrated structure and standardized interface design, enabling it to adapt to the high-speed assembly process of automated production lines, ensuring consistency and processing efficiency in mass production.

[0050] In the research and development and large-scale production of power equipment, static var generators (SVAs) that are easy to automate can be used to perform dynamic compensation performance testing on key components such as grid connection modules. These SVAs need to have standardized structures and interface compatibility to meet the rapid assembly requirements of automated production lines. For high-voltage, high-capacity SVAs, the compactness of the topology, the control response speed, and the consistency of manufacturing processes all significantly affect the operational stability and production efficiency of the power grid system. In existing technologies, traditional SVAs often employ multi-layer cascaded structures and discrete power device welding processes. Their manufacturing process relies on manual positioning and welding, making them suitable for small-batch customized production. However, in large-scale manufacturing, they suffer from complex processes, poor consistency, and high production costs, making it difficult to improve product yield and production efficiency. Therefore, there is a need to provide a new SVA that is easy to automate.

[0051] This disclosure provides a static var generator (SVA) that is easy to automate. The SVA provided in this disclosure is specifically designed for dynamic compensation in high-voltage power systems. It adopts a modular integrated structure and a standardized interface system, resulting in a compact and stable structure with high consistency in performance parameters. It is suitable for quantitative testing of key compensation performance parameters such as response time and harmonic distortion rate of critical components such as grid access modules.

[0052] To facilitate the description of the structure of the static var generator (SVR) designed for automated manufacturing, unless otherwise specified, this manual describes the structure of the equipment with the power output direction perpendicular to the generator when it is naturally placed. The "inner side" refers to the surface that directly contacts the power cabinet, located on the side of the SVR closest to the cabinet for automated manufacturing. Furthermore, the terms "front," "back," "left," "right," "top," and "bottom" in this manual are defined based on the orientation of the SVR in its standard installation state.

[0053] refer to Figures 1 to 3 In some examples, the static var generator (SVM) designed for automated manufacturing includes a housing 100 and at least two circuit boards. The housing 100 has an assembly cavity 150 with an assembly wall inside. At least two circuit boards are mounted on the assembly wall, with adjacent circuit boards spaced apart or staggered. Different functional components are provided on different circuit boards, and at least some circuit boards are electrically connected to each other. During the assembly of the SVM, at least two circuit boards are assembled in the same process.

[0054] Specifically, the housing 100 provides support and protection for the entire static var generator, while the mounting cavity 150 provides a stable mounting space for the circuit boards. The mounting wall, located within the mounting cavity 150, provides a precise positioning reference for the circuit board installation. As a functional component of the static var generator, at least two circuit boards can be installed, each mounted on the mounting wall. These circuit boards are spaced apart or staggered, ensuring electrical isolation between them while achieving a compact structural layout.

[0055] Different functional components are installed on different circuit boards, and these components work together to achieve the various performance indicators of the static var generator. At least some circuit boards are electrically connected to achieve signal transmission and interaction, ensuring the stable flow of signals inside the static var generator.

[0056] During the assembly of the static var generator, at least two circuit boards are assembled in the same process, which greatly improves production efficiency and reduces production costs.

[0057] By assembling multiple circuit boards in the same process, the production flow is simplified, manual intervention and assembly time are reduced, and assembly consistency and reliability are improved. This design enables the static var generator to better adapt to the high-speed assembly requirements of automated production lines, thereby meeting the requirements of large-scale production.

[0058] Furthermore, the design of the housing 100 also fully considers the needs of automated processing. The housing 100 includes a bottom shell 110, a front panel 120, a rear panel 130, and a cover plate 140. These components are connected together in a detachable manner, facilitating the assembly and disassembly of the static var generator. At the same time, the heat dissipation holes 160 and the connecting posts 170 on the bottom shell 110 not only improve the heat dissipation capacity of the static var generator but also provide stable support and positioning for the installation of the circuit board.

[0059] In practical applications, this type of static var generator (SVR) that facilitates automated manufacturing demonstrates significant advantages. Its modular integrated structure and standardized interface design allow the SVR to easily adapt to various automated production lines, enabling high-speed and efficient assembly processes. Furthermore, due to its compact and stable structure and high consistency in performance parameters, the SVR ensures that mass-produced products possess excellent signal processing performance, providing strong support for optimizing the performance of communication systems.

[0060] refer to Figures 1 to 3 In some examples, the mounting wall is the bottom wall of the mounting cavity 150, and at least two circuit boards include: The first circuit board 210 is detachably connected to the bottom wall; The second circuit board 230 is detachably connected to the bottom wall and the connection position is spaced apart from the second circuit board 230; The third circuit board 220 is detachably connected to the bottom wall, either directly or indirectly, and the third circuit board 220 is at least partially located between the first circuit board 210 and the second circuit board 230.

[0061] This layout makes full use of the space within the assembly cavity 150, resulting in a more compact and orderly arrangement of the circuit boards. Specifically, the first circuit board 210 and the second circuit board 230 can be arranged parallel to each other on the bottom wall, with sufficient electrical isolation between them ensured through spacing, thus avoiding signal interference. The third circuit board 220 is at least partially located between the first circuit board 210 and the second circuit board 230. This staggered arrangement not only further improves space utilization but may also help optimize the electrical performance of the static var generator, such as reducing signal transmission paths and improving signal processing efficiency.

[0062] In actual assembly, the first circuit board 210, the second circuit board 230, and the third circuit board 220 are all detachably connected to the bottom wall. This design makes the assembly and maintenance of the static var generator more convenient. When a circuit board needs to be replaced or repaired, it can simply be removed from the bottom wall without disassembling the entire static var generator, greatly improving maintenance efficiency.

[0063] Furthermore, this static var generator, which is easy to automate, also has good scalability. Depending on actual needs, more circuit boards can be added within the assembly cavity 150 to achieve more complex signal processing functions. At the same time, because the circuit boards are connected using standardized interfaces, the newly added circuit boards can be easily compatible and integrated with existing circuit boards without requiring large-scale modifications to the overall structure.

[0064] The static var generator disclosed herein, which is easy to automate, achieves advantages such as compact structure, stable performance, and ease of assembly and maintenance through ingenious circuit board layout and detachable connection method, providing strong support for signal processing of high-frequency communication equipment.

[0065] Furthermore, in actual assembly scenarios, the assembly process for the static var generator structure containing the first, second, and third circuit boards 220 has clear steps and key points.

[0066] Step S100: Place the bottom shell 110 on a suitable assembly platform, ensuring it is in a horizontal and stable state. Since the bottom shell 110 has multiple connecting posts 170 at its bottom wall position, these connecting posts 170 provide a precise positioning reference for the subsequent installation of the circuit board.

[0067] Step S200: Install the first circuit board 210. The operator aligns the first circuit board 210 with the corresponding connecting post 170 on the bottom wall and secures it detachably to the bottom wall using screws. During installation, a professional torque wrench or screwdriver must be used to tighten the screws to the specified torque value to ensure the stability of the first circuit board 210 installation and to avoid damaging the circuit board or connecting post 170 due to excessive torque.

[0068] Step S300: After completing the installation of the first circuit board 210, assemble the second circuit board 230. The second circuit board 230 is also detachably fixed to the bottom wall using screw connections. However, it is important to note that the connection position of the second circuit board 230 should be spaced apart from that of the first circuit board 210 to ensure sufficient electrical isolation and prevent signal interference. When installing the second circuit board 230, carefully adjust its position to maintain a suitable distance from the first circuit board 210, and tighten the screws again using a torque wrench to the specified torque.

[0069] Step S400: Install the third circuit board 220. The third circuit board 220 is directly or indirectly detachably connected to the bottom wall and is at least partially located between the first circuit board 210 and the second circuit board 230. If the third circuit board 220 is directly connected to the bottom wall, the operation method is similar to that of the first and second circuit boards 230, and it is fixed to the corresponding connecting post 170 on the bottom wall with screws. If the third circuit board 220 is indirectly connected to the bottom wall, for example, through a connecting bracket, the connecting bracket must be installed on the bottom wall first, and then the third circuit board 220 is installed on the connecting bracket. Similarly, the stability and positional accuracy of the installation must be ensured. When installing the third circuit board 220, electrical isolation and structural fit between it and the first and second circuit boards 230 must be ensured to avoid problems such as short circuits or collisions.

[0070] Step S500: After all three circuit boards are installed, perform electrical connections between them. For cases where at least some circuit boards require electrical connections, signal transmission and interaction can be achieved through soldering or plugging (using ribbon cables if necessary). For example, if an electrical connection is required between the first circuit board 210 and the third circuit board 220, soldering can be performed at the corresponding pads or interfaces, or suitable connectors can be used for plugging. During the electrical connection process, ensure the quality of soldering or the secure insertion of connectors to prevent problems such as cold solder joints or poor contact, ensuring stable signal flow within the static var generator.

[0071] Step S600: After completing the circuit board installation and electrical connections, assemble the remaining parts of the housing 100. The front panel 120 and rear panel 130 are detachably connected to the two side openings of the bottom housing 110, respectively. The connection can be made using screws or snap-fit ​​connections, ensuring a tight fit and improving the overall sealing and protection level of the static var generator. Then, the cover plate 140 is detachably connected to the top opening of the bottom housing 110, completing the enclosure of the housing 100. During assembly, pay attention to the fitting accuracy between components to avoid excessive gaps or improper installation.

[0072] Step S700: Conduct a comprehensive inspection and testing of the assembled Static Var Generator (SVA). Check the correct installation positions of each circuit board, the firmness of electrical connections, and the tightness of the housing assembly. Simultaneously, use professional testing equipment to test various performance indicators of the SVA, such as insertion loss, out-of-band rejection, and other key filtering performance parameters, to ensure that the SVA meets design requirements and usage standards. If any problems are found during the inspection and testing process, rework and repair must be carried out promptly until all performance indicators of the SVA meet the qualification standards.

[0073] refer to Figures 1 to 3 In some examples, the first circuit board 210 is mounted in the region of the assembly cavity 150 near the first side, the second circuit board 230 is mounted in the region of the assembly cavity 150 near the second side, and the third circuit board 220 is mounted in the central region of the assembly cavity 150.

[0074] In this disclosure, the first circuit board 210 is installed in the region of the assembly cavity 150 near the first side, and the second circuit board 230 is installed in the region near the second side, so that the two circuit boards are spatially separated from each other, effectively avoiding possible signal interference between them and ensuring the stable operation of their respective functional components.

[0075] The third circuit board 220 is installed in the middle area of ​​the assembly cavity 150. On the one hand, it can make full use of the space inside the housing 100 to achieve a compact structural layout and reduce the overall volume of the static var generator; on the other hand, this layout is conducive to signal transmission and interaction between the circuit boards.

[0076] The third circuit board 220 in the middle position can be easily electrically connected to the first and second circuit boards 230 on both sides, ensuring that the signal can flow smoothly between the circuit boards and work together to achieve the various performance indicators of the static var generator.

[0077] In practical applications, this layout also facilitates heat dissipation for the static var generator. Because the three circuit boards are relatively evenly distributed within the assembly cavity 150, heat will not be excessively concentrated in any one area. The first and second circuit boards 230 are located on the sides, and the heat they generate can dissipate into the surrounding space; the third circuit board 220 is located in the center, and its heat can also be dissipated through heat exchange with the surrounding air and conduction through contact with the housing 100.

[0078] Meanwhile, in order to further improve the heat dissipation effect, heat dissipation structures such as heat dissipation holes 160 can be set on the housing 100 to accelerate the heat dissipation and ensure that the static var generator maintains stable performance parameters during long-term operation.

[0079] In addition, this layout also facilitates the assembly and maintenance of the static var generator.

[0080] During the assembly process, operators can install the first, second, and third circuit boards 220 in sequence from both sides to the middle. The installation position of each circuit board is clear, and the operating space is relatively independent, which reduces the assembly difficulty and improves the assembly efficiency.

[0081] During maintenance, if it is necessary to inspect or replace a certain circuit board, the corresponding part of the housing 100 can be easily opened to operate on the circuit board without causing excessive interference to other circuit boards.

[0082] refer to Figures 1 to 3 In some examples, the first circuit board 210 and the second circuit board 230 are both fixedly connected to the bottom wall by fasteners, and the two sides of the third circuit board 220 are respectively connected to the first circuit board 210 and the second circuit board 230.

[0083] The first circuit board 210 and the second circuit board 230 of this disclosure are fixedly connected to the bottom wall by fasteners, such as screws and bolts. This connection method can provide stable support for the circuit board and ensure that it will not be displaced due to vibration or other reasons during the operation of the static var generator, thereby ensuring the stable operation of the functional components on the circuit board and maintaining the consistency of the performance parameters of the static var generator.

[0084] For example, in some high-frequency communication equipment applications, static var generators need to work stably for a long time. A solid connection can prevent signal processing abnormalities caused by loose circuit boards and ensure communication quality.

[0085] The third circuit board 220 is connected to the first circuit board 210 and the second circuit board 230 on both sides respectively. This connection method not only realizes the electrical connection between the circuit boards, but also plays a role in structural support.

[0086] In terms of electrical connections, it enables signals to be transmitted and interact smoothly between the three circuit boards, working together to complete the signal processing function of the static var generator.

[0087] For example, the first circuit board 210 provides stable power to the capacitor circuit board, the second circuit board 230 performs signal filtering, and the third circuit board 220 realizes signal inversion and amplification. The three circuit boards work closely together through this connection method to achieve the various performance indicators of the static var generator.

[0088] In terms of structural support, the third circuit board 220 is connected between the first and second circuit boards 230, which enhances the structural stability of the entire circuit board assembly and improves the overall vibration and impact resistance of the static var generator.

[0089] Meanwhile, this connection method also offers certain conveniences during assembly. When installing the third circuit board 220, the first and second circuit boards 230 can be used as positioning references to quickly and accurately determine its installation position, thereby improving assembly efficiency.

[0090] Furthermore, during subsequent maintenance and repair, if it is necessary to replace or repair the third circuit board 220, it is only necessary to disconnect it from the first and second circuit boards 230. The operation is relatively simple and will not cause too much impact on other circuit boards.

[0091] To further optimize this connection method, a buffer structure can be provided at the connection between the third circuit board 220 and the first and second circuit boards 230.

[0092] For example, by using buffering elements such as rubber pads and springs, when the static var generator is subjected to external impact or vibration, the buffering structure can absorb some of the energy, reduce the impact force on the circuit board, protect the functional components on the circuit board from damage, and extend the service life of the static var generator.

[0093] In addition, materials with good electrical conductivity can be used in the connection parts to ensure the reliability of the electrical connection, reduce signal transmission losses, and improve the performance of the static var generator.

[0094] In some examples, the two sides of the third circuit board 220 are connected to the first circuit board 210 and the second circuit board 230 respectively by fasteners, and the connection position is increased by the isolation member 240 to increase the assembly spacing.

[0095] This design plays a significant role in ensuring the performance and stability of the static var generator.

[0096] The fastener connection ensures a secure connection between the third circuit board 220 and the first and second circuit boards 230. Even when subjected to external factors such as vibration during the operation of the static var generator, it will not easily loosen or fall off, thus maintaining a stable electrical connection between the circuit boards and ensuring smooth signal transmission.

[0097] The addition of isolators 240 at the connection point increases the assembly spacing, which effectively achieves electrical isolation between circuit boards, prevents signals on different circuit boards from interfering with each other, and ensures the accuracy and purity of the static var generator's signal processing.

[0098] For example, in some communication systems with extremely high signal quality requirements, this electrical isolation can prevent data transmission errors caused by signal interference and improve communication reliability.

[0099] On the other hand, increasing the assembly spacing also provides better conditions for heat dissipation of the circuit board.

[0100] When the static var generator operates for a long time, each circuit board will generate heat. Sufficient spacing facilitates air circulation, accelerates heat dissipation, and prevents the circuit board temperature from becoming too high due to heat accumulation, which would affect its performance and lifespan.

[0101] At the same time, this design also makes the assembly process convenient.

[0102] During installation, the isolator 240 can serve as a clear positioning marker, helping operators to quickly and accurately determine the connection position between the third circuit board 220 and the first and second circuit boards 230, thereby improving assembly efficiency and accuracy.

[0103] Moreover, the larger assembly spacing makes it easier for operators to inspect, replace or repair the circuit boards during subsequent maintenance and repair work, reducing operational difficulties caused by limited space and lowering maintenance costs.

[0104] refer to Figures 1 to 3 In some examples, the first circuit board 210 is a capacitor circuit board, the second circuit board 230 is a filter circuit board, and the third circuit board 220 is an inverter circuit board, with the inverter circuit board positioned higher than the other two circuit boards.

[0105] This disclosure designs the first circuit board 210 as a capacitor circuit board, whose core function is to provide stable and accurate capacitance parameters for the entire static var generator system, ensuring effective storage and release of electrical energy during signal processing and maintaining stable circuit operation. The capacitor circuit board can integrate various capacitor components of different specifications and capacitance values ​​as needed. These components are laid out and matched according to the required parameters to meet the operating requirements of the static var generator under different frequencies and signal strengths.

[0106] The second circuit board 230 is a filter circuit board, which performs filtering processing on the input signal. Through a series of carefully designed filter circuits, such as low-pass filtering, high-pass filtering, and band-pass filtering, noise and interference components in the signal can be effectively removed, extracting the desired clean signal. The component layout and circuit design on the filter circuit board have been rigorously optimized to ensure efficient filtering effects under different operating environments, improving signal quality and reliability.

[0107] The third circuit board 220 is configured as an inverter circuit board, capable of converting direct current (DC) to alternating current (AC), or transforming parameters such as frequency and phase of AC. In the static var generator (SVM) system, the inverter circuit board plays a role in signal conversion and amplification, further processing and enhancing the filtered signal to meet the requirements of subsequent equipment or systems.

[0108] Placing the inverter circuit board higher than the other two circuit boards offers several advantages.

[0109] The elevated position allows the inverter circuit board to fully utilize the upper space inside the housing 100, creating a staggered layout with the other two circuit boards. This avoids mutual obstruction and interference between the circuit boards, improving overall space utilization. This layout also facilitates heat dissipation between the circuit boards. Since the inverter circuit board generates heat during operation, placing it at a higher position allows for upward heat dissipation, creating better convection with the surrounding air and accelerating heat removal. Simultaneously, maintaining a certain height difference with the other two circuit boards prevents heat accumulation between them, helping to maintain the temperature stability of the entire static var generator system and ensuring its reliability.

[0110] The higher position of the inverter circuit board does not affect its signal transmission and interaction with the other two circuit boards. Through proper circuit design and connection methods, such as using flexible circuit boards or ribbon cables, smooth signal flow between the three circuit boards can be ensured. Furthermore, the higher position provides more operating space for electrical connections, facilitating wiring connections and debugging by operators, and improving assembly and maintenance efficiency.

[0111] In practical applications, this design, which involves specific layout and functional settings for capacitor circuit boards, filter circuit boards, and inverter circuit boards, enables the static var generator (SVA) system to achieve a complete process from signal storage and filtering to signal conversion and amplification. The various circuit boards collaborate closely to achieve the SVA's performance targets, providing a stable and reliable signal processing solution for fields such as high-frequency communication equipment and power electronic equipment. Furthermore, this design facilitates further optimization and upgrades of the SVA; for example, the specifications and parameters of the circuit boards can be adjusted according to actual needs, or other functional circuit boards can be added to meet the requirements of different application scenarios.

[0112] refer to Figures 1 to 3 In some examples, the capacitor circuit board is provided with multiple capacitor structures 211 and a fan mounting plate 212. The capacitor structures 211 are used to provide electrical energy, and the fan mounting plate 212 is used to fix the fan. The inverter circuit board is provided with a heat sink 231, which is adapted to the fan. The fan can drive airflow through the heat sink 231 and complete the heat dissipation. The filter circuit board is provided with multiple staggered parallel magnetic rings 221.

[0113] Multiple capacitor structures 211 are installed on the capacitor circuit board. These capacitor structures 211 are electronic components for the storage and release of electrical energy in the static var generator. These capacitor structures 211 can quickly store and release electrical energy according to the working requirements of the static var generator, providing reliable power support for the stable operation of the static var generator.

[0114] The fan mounting plate 212 provides a fixed foundation for the subsequent installation of the fan. As an important part of the heat dissipation system, the stability of the fan installation directly affects the heat dissipation effect.

[0115] By accurately fixing the fan to the capacitor circuit board using the fan mounting plate 212, it is possible to ensure that the fan operates stably during operation and provide continuous and effective heat dissipation for the static var generator.

[0116] The heat sink 231 on the inverter circuit board is matched with the fan, and this design is the core of the heat dissipation system. The heat sink 231 is usually made of a material with good thermal conductivity, which can quickly conduct away the heat generated during the operation of the inverter circuit board. The fan drives airflow through the heat sink 231, accelerating the dissipation of heat and forming an efficient heat dissipation cycle.

[0117] When the static var generator is working, the inverter circuit board generates a lot of heat. The heat sink 231 quickly absorbs the heat and conducts it to the surface. The airflow blown out by the fan carries away the heat from the surface of the heat sink 231, thereby effectively reducing the temperature of the inverter circuit board and ensuring its stable performance.

[0118] Multiple interleaved parallel magnetic rings 221 are set on the filter circuit board, which is the key structure for realizing the filtering function.

[0119] The magnetic ring 221 has unique electromagnetic properties and can filter the passing signals.

[0120] The interleaved parallel connection of multiple magnetic rings 221 can enhance the filtering effect and expand the filtering frequency band.

[0121] Signals of different frequencies will be impeded and attenuated to varying degrees when passing through these magnetic rings 221, thereby filtering out or retaining signals of specific frequencies, ensuring that the static var generator outputs signals that meet the requirements, improving the quality and purity of the signal, and meeting the stringent signal processing requirements of different application scenarios.

[0122] refer to Figures 1 to 3 In some examples, housing 100 includes a bottom shell 110, a front panel 120, a rear panel 130, and a cover plate 140. The bottom shell 110 is a U-shaped plate with a top opening and two side openings. The front panel 120 and the rear panel 130 are detachably connected to the two side openings, respectively, and the cover plate 140 is detachably connected to the top opening. At least two of the bottom shell 110, front panel 120, rear panel 130 and cover plate 140 are provided with heat dissipation holes 160. The bottom shell 110 is provided with multiple connecting posts 170 at the position corresponding to the bottom wall. The first circuit board 210, the second circuit board 230 and the third circuit board 220 are respectively connected to the bottom shell 110 through the connecting posts 170, and the assembly gap is increased through the connecting posts 170.

[0123] At least two of the bottom shell 110, front panel 120, rear panel 130, and cover plate 140 have heat dissipation holes 160, forming a multi-directional heat dissipation channel. When the static var generator is working, the heat generated by the internal circuit board can be fully exchanged with the outside air through these heat dissipation holes 160.

[0124] For example, hot air can be exhausted from the heat dissipation holes 160 of the bottom shell 110, while cooler outside air can enter from the heat dissipation holes 160 of the front panel 120 or the rear panel 130, forming convection, accelerating heat dissipation, effectively reducing the internal temperature of the static var generator, and ensuring that each circuit board works stably in a suitable temperature environment.

[0125] The multiple connecting posts 170 located on the bottom wall of the base shell 110 not only connect the circuit boards but also play a crucial role in improving heat dissipation. The first circuit board 210, the second circuit board 230, and the third circuit board 220 are connected to the base shell 110 via these connecting posts 170, creating a certain assembly gap between the circuit boards and the base shell 110. This gap provides space for airflow, allowing air to flow freely between the circuit boards and the base shell 110, carrying away the heat generated by the circuit boards.

[0126] Moreover, this assembly gap can prevent the circuit board from directly contacting the bottom shell 110, reduce the impact of heat conduction on the circuit board, and further improve the heat dissipation effect.

[0127] Furthermore, this heat dissipation design takes into account the heat dissipation requirements of the static var generator under different operating environments. In some high-temperature, high-load operating scenarios, the heat dissipation holes 160 and the assembly gap can quickly and effectively dissipate heat, preventing the static var generator from experiencing performance degradation or damage due to overheating. In environments with relatively low heat dissipation requirements, this design can also ensure that the static var generator maintains stable performance during long-term operation, extending its service life.

[0128] Meanwhile, this heat dissipation design also has a certain degree of flexibility and scalability. If the heat dissipation effect is found to be unsatisfactory in actual applications, the heat dissipation performance can be further optimized by increasing the number of heat dissipation holes 160, expanding the area of ​​heat dissipation holes 160, or adjusting the height of connecting posts 170, so as to meet the needs of different users.

[0129] In some examples, the base 110 includes a mounting base plate 111 and protective side plates 112 disposed on both sides of the mounting base plate 111, and at least two circuit boards are directly or indirectly mounted on the mounting base plate 111.

[0130] The mounting base plate 111 provides a stable foundation platform for the installation of the circuit board. Its flat surface and appropriate size design ensure the flatness and stability of the circuit board during installation.

[0131] During installation, the circuit board can be firmly fixed to the mounting base plate 111 using various connection methods, such as the aforementioned fasteners and fixtures, to prevent displacement due to vibration or other reasons during operation, thereby ensuring the stability of the static var generator's performance.

[0132] The protective side plates 112 installed on both sides of the assembly base plate 111 provide multi-faceted protection.

[0133] On the one hand, the protective side plate 112 can prevent external objects from directly colliding with the circuit board, avoiding damage to the components on the circuit board due to external impact. For example, in some complex working environments, various debris may be splashed, and the protective side plate 112 can effectively block these debris and protect the safety of the circuit board.

[0134] On the other hand, the protective side plate 112 also provides electromagnetic shielding to a certain extent. During the operation of the static var generator, the circuit board generates electromagnetic signals. If these electromagnetic signals leak into the outside world, they may interfere with surrounding electronic equipment; at the same time, external electromagnetic interference may also affect the normal operation of the static var generator. The protective side plate 112 can reduce the leakage of electromagnetic signals and the entry of external electromagnetic interference, providing a relatively stable electromagnetic environment for the circuit board, thereby improving the anti-interference capability and operational reliability of the static var generator.

[0135] Moreover, this bottom shell 110 structure also offers certain conveniences during assembly.

[0136] When installing the circuit board, the operator can first place the circuit board on the assembly base plate 111 for initial positioning, and then use the protective side plate 112 as an auxiliary positioning to quickly and accurately complete the installation of the circuit board.

[0137] In subsequent maintenance and repair work, the protective side plate 112 can also be easily disassembled, providing operators with sufficient operating space to facilitate the inspection, replacement or repair of the circuit board, thereby improving maintenance efficiency and reducing maintenance costs.

[0138] In some examples, the plurality of connecting posts 170 include a first connecting post 170 for connecting a first circuit board 210, a second connecting post 170 for connecting a second circuit board 230, and a third connecting post 170 for connecting a third circuit board 220. Alternatively, the plurality of connecting posts 170 may include a first connecting post 170 for connecting the first circuit board 210 and a second connecting post 170 for connecting the second circuit board 230, and a third circuit board 220 may be alternately arranged above the first circuit board 210 and the second circuit board 230, and the first circuit board 210 and the second circuit board 230 may be respectively provided with a separator 240 connected to the third circuit board 220.

[0139] When multiple connecting posts 170 are used, including a first connecting post 170 for connecting the first circuit board 210, a second connecting post 170 for connecting the second circuit board 230, and a third connecting post 170 for connecting the third circuit board 220, each circuit board has a dedicated corresponding connecting post 170 for connection. This one-to-one correspondence makes the connection more precise and reliable.

[0140] During assembly, operators can clearly identify the circuit board corresponding to each connecting post 170. Following the predetermined assembly sequence and requirements, the first circuit board 210 is accurately installed on the first connecting post 170, the second circuit board 230 on the second connecting post 170, and the third circuit board 220 on the third connecting post 170. This effectively avoids installation errors and improves assembly accuracy and efficiency. Furthermore, this independent connection method allows each circuit board to withstand external forces or vibrations relatively independently, reducing the impact of vibration or loosening of one circuit board on other circuit boards, thereby improving the stability and reliability of the entire static var generator structure.

[0141] Meanwhile, in subsequent maintenance and repair work, if a circuit board has a problem, only the corresponding connecting post 170 of the circuit board needs to be operated to disassemble and replace the circuit board, which will not interfere with the connection of other circuit boards, thus reducing the difficulty and cost of maintenance.

[0142] If a design is adopted in which multiple connecting posts 170 are used, including a first connecting post 170 for connecting the first circuit board 210 and a second connecting post 170 for connecting the second circuit board 230, and a third circuit board 220 is staggered above the first circuit board 210 and the second circuit board 230, and the first circuit board 210 and the second circuit board 230 are respectively provided with isolation members 240 connected to the third circuit board 220, then there are unique advantages.

[0143] The third circuit board 220 is staggered at the top, achieving a layered layout of the circuit boards. This layered structure not only facilitates electrical isolation and reduces electromagnetic interference between different circuit boards, but also provides better conditions for heat dissipation. The principle of hot air rising makes it easier for the heat generated by the third circuit board 220 to dissipate upwards, while the heat generated by the first circuit board 210 and the second circuit board 230 can also circulate better within their respective spaces.

[0144] The spacers 240 provided on the first circuit board 210 and the second circuit board 230 serve a positioning and support function when connected to the third circuit board 220. During assembly, the spacers 240 help operators quickly and accurately determine the installation position of the third circuit board 220, improving assembly efficiency.

[0145] Furthermore, the isolation component 240 can increase the assembly spacing between the third circuit board 220 and the first and second circuit boards 230, which provides space for air circulation and further enhances the heat dissipation effect.

[0146] During maintenance and repair, the larger assembly spacing makes it easier for operators to inspect, replace or repair the third circuit board 220, and also facilitates related operations on the first circuit board 210 and the second circuit board 230, thus improving the maintainability of the entire static var generator.

[0147] Although embodiments of the present disclosure have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present disclosure, and such modifications and variations all fall within the scope defined by the appended claims.
