Description

Technical Field

[0001] This invention relates to the field of power equipment, and more specifically to a three-phase imbalance regulation system. Background Technology

[0002] Three-phase load imbalance switching regulators (SPCs) are power quality management devices applied to the user side of low-voltage power distribution. They improve power quality and system efficiency by comprehensively compensating for three-phase current imbalance, reactive power, and harmonics. The device analyzes the unbalanced current components (positive sequence, negative sequence, and zero sequence) and reactive power demand in the power grid in real time based on control algorithms, and drives an inverter through power devices to generate corresponding offsetting currents, thereby achieving three-phase balance and reactive power compensation.

[0003] Currently, when installing such regulating devices in distribution cabinets, they are typically fixed directly to the mounting base or bracket. During wiring, due to the cabinet layout requiring short and neat wiring, operators often need to simultaneously perform multiple actions within a limited space, such as tightening cables, aligning terminals, and securing bolts. This process not only demands a high level of operator skill but is also prone to inefficiency, inconsistent wiring quality, and even safety hazards such as poor contact due to wiring difficulties.

[0004] Therefore, how to provide a three-phase imbalance adjustment system that is easy to wire and operate, can effectively reduce installation difficulty and improve installation efficiency has become a technical problem that needs to be solved. Summary of the Invention

[0005] This invention aims to address one of the technical problems in related technologies to a certain extent. To this end, this invention provides a three-phase imbalance adjustment system that reduces wiring difficulty and improves installation efficiency and ease of operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A three-phase imbalance regulation system, comprising: Base; Three-phase regulation module; A circumferential adjustment assembly includes a support turntable rotatably mounted on the base and a first locking component for locking the support turntable at different circumferential angles; A linear sliding assembly includes a guide rail fixedly mounted on the carrier turntable and a sliding mounting component that slides in cooperation with the guide rail; The three-phase adjustment module is mounted on the guide rail via the sliding mounting component, so that the three-phase adjustment module can move linearly along the guide rail and can rotate circumferentially relative to the base by the rotation of the bearing turntable.

[0007] In this application, the three-phase adjustment module is mounted on the guide rail via the sliding mounting component, enabling the three-phase adjustment module to move linearly along the guide rail fixed to the carrier turntable. Furthermore, by providing a circumferential adjustment component, the three-phase adjustment module can rotate horizontally relative to the base along with the carrier turntable. For example, after the three-phase adjustment module approaches the connecting wire via linear sliding, rotating the carrier turntable can adjust the orientation of the three-phase adjustment module's wiring port, aligning it with and bringing it close to the fixed connecting wire terminal. This combination of two degrees of freedom of movement gives the three-phase adjustment module the ability to actively adapt to the fixed wiring point, thereby changing the installation mode from "fixed equipment, forcefully pulling the connecting wire" to "moving the equipment, conforming to the connecting wire," eliminating the complex operations of pulling the wire, aligning the hole, holding the wire, and tightening simultaneously, thus improving installation efficiency and convenience.

[0008] Optionally, the first locking component includes a plurality of first sockets disposed on the base and fasteners disposed on the carrier turntable, wherein the fasteners can be selectively inserted into any of the first sockets to fix the angle of the carrier turntable.

[0009] The circumferential adjustment assembly also includes a first locking component for locking the carrier turntable at any desired rotation angle. Specifically, the base has multiple first insertion holes, and the carrier turntable has at least one threaded hole perpendicular to the turntable surface. Threaded fasteners such as bolts and studs are screwed into one of the threaded holes. When it is necessary to lock the angle of the three-phase adjustment module, the carrier turntable is rotated to the target position, and then the aforementioned fasteners are tightened towards the base. The end of the fastener is then screwed into one of the first insertion holes on the base that aligns with the threaded hole. The mechanical interference between the fastener end and the wall of the first insertion hole prevents the carrier turntable from continuing to rotate, thus achieving circumferential angle fixation and anti-rotation of the three-phase adjustment module fixed to the carrier turntable. In addition, to improve positioning reliability, a locking nut or elastic washer can be added to the threaded component to prevent it from loosening under vibration.

[0010] Optionally, the plurality of the first sockets are arranged in a circular array with the center of the base as the center.

[0011] With the axis of the rotating shaft as the center, multiple first insertion holes are machined on the base, evenly distributed along the circumference. These multiple first insertion holes together form an angle positioning plate. The first insertion holes, arranged in a circumferential array, provide multiple locking positions for the rotation of the turntable, improving the flexibility of the three-phase adjustment module.

[0012] Optionally, the sliding mounting component includes a slider fixedly connected to the three-phase adjustment module and a second locking component for locking the slider at different linear positions on the guide rail.

[0013] The sliding mounting component in the linear sliding assembly specifically includes a slider rigidly connected to the back of the three-phase adjustment module. The slider is configured to slide against a guide rail fixed to the support turntable, allowing the three-phase adjustment module to gain linear freedom of movement along the axial direction of the guide rail. Furthermore, a locking mechanism can fix the slider (along with the three-phase adjustment module it is fixed to) to the desired position on the guide rail, thereby achieving module positioning.

[0014] Optionally, the second locking component includes a plurality of second sockets and a pin disposed on the guide slide rail. The slider is provided with a through hole, and the pin can pass through the through hole and be inserted into any of the second sockets to fix the position of the slider.

[0015] The top surface of the guide rail has multiple second insertion holes evenly spaced along its length. After the three-phase adjustment module is pushed to slide along the guide rail to a suitable linear position, the operator inserts a pin (either a cylindrical pin or a cotter pin) vertically. This pin passes sequentially through the through hole on the slider and the corresponding second insertion hole on the guide rail, thus mechanically restricting the relative sliding between the slider and the rail, locking the three-phase adjustment module in the linear position.

[0016] Optionally, the slider has a C-shaped cross-section to form a cavity with an opening on one side inside, the cavity being used to engage the guide rail; elastic locking blocks protruding toward each other into the cavity are provided on opposite sides of the opening.

[0017] The slider's cross-section is designed in a C-shape, forming an internal cavity with an opening on one side. The contour dimensions of this cavity match the cross-sectional contour of the guide rail, allowing the guide rail to engage with the opening and enabling the slider to slide smoothly in a straight line. Additionally, elastic blocks made of polyurethane or rubber are provided on the inner walls of both sides of the cavity opening.

[0018] Optionally, the opposing end faces of the two elastic blocks are both constructed as guide ramps, and the two guide ramps form a trapezoidal guide opening for guiding the guide rail.

[0019] The opposing surfaces of the two elastic blocks are machined into guide bevels, which together form a trapezoidal guide opening that is narrow at the entrance and wide inside. During installation, the slider is aligned with the guide rail, and the guide opening guides the guide rail to open the elastic blocks and slide them into the cavity. The rebound force generated by the elastic blocks provides clamping force to the guide rail, reducing wobbling.

[0020] Optionally, a water-blocking structure is fixedly installed on the bearing turntable above the three-phase adjustment module.

[0021] By installing a water-blocking structure above the three-phase regulating module, falling liquids (such as condensation or accidental splashes) can be intercepted, preventing direct contact between the liquid and the live parts of the three-phase regulating module, thus preventing short circuits, corrosion, or insulation failures. Therefore, the water-blocking structure improves the applicability of the entire regulating system in humid, condensation-prone, or accidental water-spraying environments.

[0022] Optionally, the water-blocking structure includes a horizontally extending transverse plate, an inclined plate extending downward from the end of the transverse plate, and a water guide groove connected to the bottom of the inclined plate.

[0023] The water-blocking structure consists of a horizontally extending transverse plate for shielding, a guide plate extending downward at a certain angle from the end of the transverse plate, and a U-shaped water guide channel connected to the bottom of the guide plate for collecting water. It can guide water droplets or condensation that may fall from above the three-phase regulating module to the water guide channel, preventing them from dripping directly onto the electrical components below. Specifically, a hose can be connected to the end of the water guide channel to guide the water to the designated drainage position of the cabinet.

[0024] Optionally, the carrier turntable is further provided with a wire clamp for fixing the connecting wire and an operating handle for rotating the carrier turntable, the operating handle being vertically mounted on the carrier turntable.

[0025] For ease of operation, a vertically welded operating handle is installed on the turntable, allowing installers to easily adjust its angle. Multiple plastic wire clips are also installed at intervals along the edge of the turntable for neatly bundling and securing the connecting wires after wiring is completed, keeping the cabinet tidy.

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain the present invention and should not be construed as limiting the invention.

[0030] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this patent. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0031] Example: This embodiment provides a three-phase imbalance adjustment system, such as Figures 1 to 3 As shown, it includes: Base 1; Three-phase regulation module 7; A circumferential adjustment assembly includes a support turntable 2 rotatably mounted on a base 1 and a first locking component for locking the support turntable 2 at different circumferential angles; A linear sliding assembly includes a guide rail 5 fixedly mounted on a support turntable 2 and a sliding mounting component that slides in cooperation with the guide rail 5; The three-phase adjustment module 7 is mounted on the guide rail 5 via a sliding mounting component, so that the three-phase adjustment module 7 can move linearly along the guide rail 5 and can rotate circumferentially relative to the base 1 by rotating the bearing turntable 2.

[0032] In this embodiment, a three-phase imbalance adjustment system for use in a low-voltage distribution cabinet is provided to solve the problem of difficult installation and wiring of the three-phase adjustment module 7 due to the short length of the pre-arranged connecting wires 9 in the distribution cabinet. Specifically, the base 1 can be fixedly connected to the mounting base plate or frame of the distribution cabinet through the mounting holes provided on its bottom, using bolts, screws, and other connecting parts, to provide a stable installation foundation for the entire system. In other embodiments, the base 1 can also be placed directly on the mounting base plate of the distribution cabinet without fixing it, so as to improve the overall flexibility of the three-phase imbalance adjustment system. A circumferential adjustment component is set above the base 1. The circumferential adjustment component includes a bearing turntable 2, which can be directly fitted onto the vertical rotating shaft 11 fixedly installed at the center of the base 1 through the shaft hole opened in its center. In addition, a retaining spring or washer can be set at the top of the rotating shaft 11 for axial limiting, so that the bearing turntable 2 can smoothly rotate around the rotating shaft 11 in the horizontal plane. A linear sliding component is fixedly set on the upper surface of the bearing turntable 2. The linear sliding assembly includes two parallel guide rails 5, each equipped with a sliding mounting component. The back frame of the three-phase adjustment module 7 can be rigidly connected to the sliding mounting component via bolts or clips. Therefore, the load of the three-phase adjustment module 7 is transferred to the guide rails 5 through the sliding mounting component, then to the load-bearing turntable 2, and finally to the base 1.

[0033] In addition, to accommodate different types of distribution cabinets or different installation space requirements, the connection between the base 1 and the load-bearing turntable 2 can be designed to be adjustable. For example, the rotating shaft 11 can be designed as a column with external threads, and then combined with adjusting washers of different thicknesses, or the rotating shaft 11 can be directly constructed as a telescopic sleeve rod, thereby achieving the purpose of adjusting the overall installation height of the load-bearing turntable 2 and enhancing the versatility of the three-phase imbalance adjustment system.

[0034] It should be noted that in this embodiment, connecting wire 9 refers to a cable or copper busbar leading from the upstream power switch (or busbar) inside the distribution cabinet, used to provide operating power to the three-phase regulating module 7. To ensure neatness, safety, and compliance with electrical installation standards within the distribution cabinet, connecting wire 9 is pre-cut to a suitable length during wiring, with terminals crimped at both ends. One end of connecting wire 9 is secured to the switch or busbar on the power supply side, and the other end (free end) is connected to the corresponding power input terminal (pencil) of the three-phase regulating module 7. It is precisely because of this fixed length characteristic of connecting wire 9 that its free end has a limited range of motion, causing the installation difficulties described in the background art; that is, the operator needs to pull this rigid short wire forcefully to align its terminals with the wiring holes on the three-phase regulating module 7. In other embodiments, connecting wire 9 can also be other cables that need to be fixedly connected to the three-phase regulating module 7, such as the signal sampling line, communication line, or grounding wire of the three-phase regulating module 7. When the end positions of these cables are fixed and the reserved length is limited, the system's adjustment function can facilitate the connection.

[0035] Specifically, the three-phase regulating module 7 in this application refers to a power quality management device used for dynamically managing three-phase current imbalance and also having reactive power compensation functions. In this application, this module is used as a fully functional single device. To achieve its power quality management function, the three-phase regulating module 7 at least includes common features such as an input power interface for connecting the power cable from the power grid (used to connect the aforementioned connecting line 9 in this embodiment) and an output management interface for injecting the compensation current generated by the three-phase regulating module 7 into the power grid. The three-phase regulating module 7 should also include a housing for fixed connection with a sliding mounting component. The core of this application is to provide a position adjustment system for the aforementioned three-phase regulating module 7 to solve problems such as difficult installation positioning and laborious wiring operations caused by the short reserved length of the connecting line 9 (especially the input power line) in the distribution cabinet and the large weight of the module itself. By enabling the three-phase regulating module 7 to have adjustment capabilities in both circumferential rotation and linear sliding, installers can easily align and secure its input power interface with the fixed short cable terminal, improving installation efficiency and reliability. Therefore, any device possessing the aforementioned general characteristics, capable of performing three-phase imbalance management and reactive power compensation functions, and requiring similar installation and wiring scenarios, falls under the category of the three-phase regulation module 7 in this application. Furthermore, this invention does not impose any limitations or improvements on its internal topology, specific control algorithms, or auxiliary circuits, and therefore will not elaborate further.

[0036] The first locking component includes a plurality of first sockets 12 disposed on the base 1 and a fastener 3 disposed on the carrier turntable 2. The fastener 3 can be selectively inserted into any of the first sockets 12 to fix the angle of the carrier turntable 2.

[0037] In this embodiment, the circumferential adjustment assembly further includes a first locking component for locking the carrier turntable 2 at any desired rotation angle. Specifically, the base 1 has multiple first insertion holes 12, and the carrier turntable 2 has at least one threaded hole perpendicular to the turntable surface. Threaded fasteners 3, such as bolts or studs, are screwed into one of the threaded holes. When it is necessary to lock the angle of the three-phase adjustment module 7, the carrier turntable 2 is rotated to the target position, and then the aforementioned fastener 3 is tightened towards the base 1. The end of the fastener 3 is then screwed into one of the first insertion holes 12 on the base 1 that aligns with the threaded hole. The mechanical interference between the end of the fastener 3 and the wall of the first insertion hole 12 prevents the carrier turntable 2 from continuing to rotate, thus achieving circumferential angle fixation and anti-rotation of the three-phase adjustment module 7 fixed to the carrier turntable 2. In addition, to improve positioning reliability, a locking nut or elastic washer can be added to the threaded component to prevent it from loosening under vibration.

[0038] Multiple first sockets 12 are arranged in a circular array with the center of the base 1 as the center.

[0039] In this embodiment, with the axis of the rotating shaft 11 as the center, a plurality of first insertion holes 12 are machined on the base 1, which are evenly distributed along the circumference. The plurality of first insertion holes 12 together constitute an angle positioning disk. The first insertion holes 12, which are arranged in a circumferential array, provide multiple locking positions for the rotation of the turntable 2, thereby improving the flexibility of the three-phase adjustment module 7.

[0040] The sliding mounting component includes a slider 13 fixedly connected to the three-phase adjustment module 7 and a second locking component for locking the slider 13 at different linear positions on the guide rail 5.

[0041] In this embodiment, the sliding mounting component in the linear sliding assembly specifically includes a slider 13 rigidly connected to the back of the three-phase adjustment module 7. The slider 13 is configured to form a sliding engagement with the guide rail 5 fixed on the support turntable 2, allowing the three-phase adjustment module 7 to obtain linear movement freedom along the axial direction of the guide rail. In addition, the slider 13 (along with the three-phase adjustment module 7 to which it is fixed) can be fixed at the desired position on the guide rail 5 by the action of the locking mechanism, thereby realizing module positioning.

[0042] The second locking component includes a plurality of second insertion holes 15 and a pin 10 disposed on the guide slide rail 5. The slider 13 is provided with a through hole 14, and the pin 10 can pass through the through hole 14 and be inserted into any of the second insertion holes 15 to fix the position of the slider 13.

[0043] In this embodiment, a plurality of second insertion holes 15 are equidistantly arranged on the top surface of the guide rail 5 along its length. After the three-phase adjustment module 7 is pushed to slide along the guide rail 5 to a suitable straight position, the operator inserts a pin 10 (which can be a cylindrical pin or a cotter pin) vertically. The pin 10 passes sequentially through the through hole 14 on the slider 13 and the corresponding second insertion hole 15 on the guide rail 5, thereby mechanically restricting the relative sliding between the slider 13 and the rail, and locking the three-phase adjustment module 7 in the straight position.

[0044] like Figure 5 and Figure 6 As shown, the cross-section of the slider 13 is C-shaped to form a cavity with an opening on one side inside, which is used to engage the guide rail 5; elastic locking blocks 16 protruding towards each other into the cavity are provided on opposite sides of the opening.

[0045] In this embodiment, the cross-section of the slider 13 is designed to be C-shaped, forming a cavity with an opening on one side. The contour dimensions of this cavity match the cross-sectional contour of the guide rail 5, allowing the guide rail 5 to be inserted into the opening and enabling the slider 13 to slide smoothly in a straight line. In addition, elastic blocks 16 made of polyurethane or rubber material are provided on the inner walls on both sides of the cavity opening.

[0046] The opposing end faces of the two elastic blocks 16 are both constructed as guide slopes, and the two guide slopes form a trapezoidal guide opening for guiding the guide slide rail 5.

[0047] In this embodiment, the opposing surfaces of the two elastic blocks 16 are machined into guide slopes, forming a trapezoidal guide opening with a narrow entrance and a wide interior. During installation, the slider 13 is aligned with the guide rail 5, and the guide opening guides the guide rail 5 to open the elastic blocks 16 and slide them into the cavity. The rebound force generated by the elastic blocks 16 provides clamping force to the guide rail 5, reducing shaking. The front ends of both elastic blocks 16 are provided with chamfers 17, which serve a guiding function.

[0048] like Figure 1 As shown, a water-blocking structure 4 is fixedly installed on the bearing turntable 2 above the three-phase adjustment module 7.

[0049] In this embodiment, by providing a water-blocking structure 4 above the three-phase regulating module 7, falling liquids (such as condensate or accidental splashes) can be intercepted, preventing the liquid from directly contacting the live parts of the three-phase regulating module 7 and preventing short circuits, corrosion, or insulation failures in the three-phase regulating module 7. Therefore, the water-blocking structure 4 improves the applicability of the entire regulating system in humid, condensation-prone, or accidental water-spraying environments.

[0050] like Figure 4As shown, the water-blocking structure 4 includes a horizontally extending transverse plate 41, an inclined plate 42 extending downward from the end of the transverse plate 41, and a water guide groove 43 connected to the bottom of the inclined plate 42.

[0051] In this embodiment, the water-blocking structure 4 is formed by sequentially connecting a horizontal plate 41 extending horizontally for shielding, a guide plate 42 extending downward from the end of the horizontal plate 41 at a certain angle, and a U-shaped water guide channel 43 connected to the bottom of the guide plate 42 for collecting water flow. This guides water droplets or condensation that may drip from above the three-phase regulating module 7 to the water guide channel 43, preventing them from dripping directly onto the electrical components below. Specifically, a hose can be connected to the end of the water guide channel 43 to guide the water to the designated drainage position of the cabinet.

[0052] The carrier turntable 2 is also equipped with a wire clamp 8 for fixing the connecting wire 9 and an operating handle 6 for rotating the carrier turntable 2. The operating handle 6 is vertically installed on the carrier turntable 2.

[0053] In this embodiment, for ease of operation, an operating handle 6 is vertically welded onto the turntable 2, allowing installers to easily adjust the angle of the turntable 2. Multiple plastic wire clips 8 are also installed at intervals along the edge of the turntable 2 for orderly bundling and securing of the connecting wires 9 after wiring is completed, keeping the cabinet tidy. Alternatively, the operating handle 6 can be designed to be foldable to save space when not in operation. Alternatively, the operating handle 6 can also be fixed to the turntable 2 with bolts.

[0054] During installation, the operator aligns the opening of the slider 13 (whose cross-section is C-shaped) with the guide rail 5 and applies vertical pressure to engage the slider 13 onto the rail. During this process, the guide ramp at the opening of the slider 13 automatically guides and centers the slider, while the elastic block 16 (such as a rubber block) inside the opening undergoes elastic deformation to allow the rail to be smoothly inserted. After the rail is in place, the restoring force of the elastic block 16 provides the initial clamping force, thus connecting the three-phase adjustment module 7 to the linear sliding assembly. To facilitate connecting the power input terminal of the three-phase adjustment module 7 to the pre-installed connection line 9 inside the cabinet, firstly, according to the actual outgoing direction of the connection line 9, slide the three-phase adjustment module 7 linearly along the guide rail 5, bringing it approximately close to that side. Next, release the first locking component (pull the bolt out of the first insertion hole 12 of the base 1), allowing the rotating platform 2 to rotate freely. By operating the operating handle 6, which is vertically mounted on the carrier turntable 2, the carrier turntable 2 can be driven to rotate with minimal effort, thereby bringing the wiring port of the three-phase adjustment module 7 close to the end of the fixed connecting wire 9.

[0055] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
