Description

Technical Field

[0001] This invention relates to the field of controller technology, and in particular to an automatic reactive power compensation controller. Background Technology

[0002] In modern power systems, with the widespread application of industrial automation equipment, nonlinear loads, and new energy power generation, the reactive power demand in the power grid is becoming increasingly complex and volatile. The rational allocation and compensation of reactive power is crucial for maintaining voltage stability in the power system, reducing line losses, improving power transmission efficiency, and ensuring power quality. If reactive power is unbalanced, it will not only lead to a decrease in the utilization rate of power equipment and an increase in line losses, but may also cause serious problems such as voltage collapse, affecting the safe and stable operation of the entire power grid. Therefore, an automatic compensation controller is needed to maintain the stability of the power grid during operation.

[0003] For example, a reactive power automatic compensation controller proposed in application number 202421095902.3 includes a base and a top cover. Connecting seats are fixedly connected to both sides of the rear end face of the base, and first fixing seats are fixedly connected to both sides of the front end face of the base. A rotating seat is fixedly connected to the rear end face of the top cover at a position opposite to the connecting seats, and a second fixing seat is fixedly connected to the front end face of the top cover at a position opposite to the first fixing seats. The rotating seat is rotatably connected within the connecting seats. A locking device secures the base and the top cover together. In summary, by setting the rotating seat and connecting seats, the rotating seat is rotatably connected to the connecting seats. When separating the shell and the cover, the cover can be flipped using the shell as a fulcrum. Furthermore, the locking device between the first and second fixing seats secures the shell and the cover together, facilitating easy assembly and disassembly.

[0004] In traditional power control systems, reactive power compensation controllers are typically fixedly installed inside electrical cabinets. However, since the controllers and wiring lines are located in different areas of the cabinet, maintenance personnel find it difficult to visually determine the corresponding connection relationships between the lines and the controller ports during inspection and maintenance. This layout makes it impossible to quickly locate and confirm the line connection status, requiring a significant amount of time to trace the line routes and connection points, which significantly reduces maintenance efficiency. Furthermore, the complex and intertwined lines can easily lead to misjudgments during maintenance, potentially causing secondary faults or safety hazards, which greatly restricts the efficient operation and stable maintenance of the power system. Summary of the Invention

[0005] This invention relates to an automatic reactive power compensation controller, which has a docking housing and an external wiring bracket. Through the integrated design of the docking housing and the external wiring bracket, the main body's connection lines are centrally led to the external wiring block, so that the external wiring block and the external lines are in the same area. During maintenance, the staff can intuitively locate the line connection points. Combined with the visible connection structure of the locking plug and the locking groove, the connection status between the docking housing and the inner block can be quickly determined. This avoids the tedious process of sorting out the lines under the traditional decentralized layout, greatly shortens the maintenance time, and reduces the risk of secondary faults caused by line misjudgment.

[0006] This invention provides an automatic reactive power compensation controller, specifically comprising: a main body; a docking plate fixedly connected to the rear side of the main body; an inner block fixedly connected to the docking plate; four sets of circumferentially distributed locking grooves on the outer wall of the inner block; two sets of docking slots on the inner block; connecting plugs fixedly connected to the interior of the two sets of docking slots; a docking cover fixedly fitted over the inner block; a docking groove for fitting over the inner block inside the docking cover; two sets of mating plates fixedly connected inside the docking cover; telescopic grooves formed inside the four sets of rectangular protrusions of the docking grooves; adjusting rods connected to the interior of the four sets of telescopic grooves through circular through holes; locking blocks slidably connected to the interior of the four sets of telescopic grooves; two sets of external wiring brackets fixedly connected to the exterior of the docking cover; external wiring strips fixedly connected to the ends of the two sets of external wiring brackets; and constraint frames provided between the two sets of external wiring strips.

[0007] Preferably, the main body has internal control circuitry; a control panel is fixedly connected to the front of the main body; and the control panel is electrically connected to the internal control circuitry of the main body.

[0008] Preferably, a digital display component is fixedly connected to the control panel; the digital display component is electrically connected to the control circuit inside the main body; a control button is fixedly connected to the control panel; the control button is electrically connected to the control circuit inside the main body; and a rear connection slot is provided on the rear side of the main body.

[0009] Preferably, the mating plate has a protrusion fixedly attached for insertion into the rear groove; the mating plate has internal connecting lines; the connecting lines of the mating plate are electrically connected to the control lines inside the main body; and rectangular slots are respectively connected to the inner sides of the four sets of locking grooves.

[0010] Preferably, the connecting plugs are electrically connected to the connecting lines inside the mating plate; four sets of rectangular protrusions distributed in a circle are fixed to the inner wall of the mating groove, and the four sets of rectangular protrusions of the mating groove are respectively inserted into the corresponding locking grooves.

[0011] Preferably, the two sets of mating inserts are respectively inserted into corresponding docking slots; the two sets of mating inserts are provided with docking holes; the two sets of mating inserts are respectively connected to corresponding connectors through docking holes; the four sets of telescopic grooves are rectangular grooves, and the inner side of the four sets of telescopic grooves is respectively connected with a rectangular through hole; the outer side of the four sets of telescopic grooves is respectively connected with a circular through hole.

[0012] Preferably, the four sets of adjusting rods are configured as threaded rod-shaped structures, and the outer side of the four sets of adjusting rods is configured as a rotating head; the four sets of locking blocks are respectively provided with threaded grooves for cooperating with the adjusting rods, and the four sets of locking blocks are respectively threadedly connected to the corresponding adjusting rods; the four sets of locking blocks are respectively inserted into the corresponding locking grooves.

[0013] Preferably, the two sets of external connectors are electrically connected to their corresponding mating plugs.

[0014] Preferably, an L-shaped frame for constraining two sets of external wiring frames is fixedly connected to the constraint frame; two sets of external fixing frames are fixedly connected to the outer wall of the constraint frame.

[0015] The reactive power automatic compensation controller provided by this invention has the following beneficial effects:

[0016] In this invention, the integrated design of the docking cover and the external terminal block concentrates the main body's connection lines to the external terminal block, placing the external terminal block and the external lines in the same area. During maintenance, staff can intuitively locate the line connection points and, combined with the visible connection structure of the locking plug and locking groove, quickly determine the connection status between the docking cover and the inner block. This avoids the tedious process of tidying up the lines under the traditional dispersed layout, significantly shortens maintenance time, and reduces the risk of secondary faults caused by line misjudgment.

[0017] In addition, the inner block and the docking cover adopt a double locking structure: the rectangular protrusion on the inner wall of the docking groove is initially positioned with the locking groove, and the locking plug is driven by the adjusting rod to insert into the rectangular slot inside the locking groove to form a mechanical fastening. At the same time, the docking hole of the connecting plug and the mating plate fits tightly to ensure stable electrical connection. This design effectively resists the influence of external forces such as vibration and line pulling in the electrical cabinet, prevents loosening of the connection, and ensures the continuous and reliable operation of the reactive power compensation function.

[0018] In addition, the controller highly integrates internal control circuits, display and operation modules (control panel, digital display component, control buttons) and external wiring components. The rear connection slot and the protruding design of the docking plate on the back of the main body enable modular assembly, which is convenient for disassembly and maintenance. The electrical connection between the mating plate inside the docking housing and the external wiring frame provides an interface for future functional expansion, which can flexibly adapt to different specifications of external equipment or upgrade and transformation needs, thereby improving the versatility of the equipment.

At this time, the inner block 7 on the rear side of the main body 1 is fixed in place with the docking plate 6, and the connecting plug 10 on the inner block 7 is connected to the internal control lines of the main body 1 via the connecting lines of the docking plate 6, preparing for subsequent external wiring.
