Abstract
Description
Technical Field
[0001] This utility model relates to the field of power quality monitoring technology, and in particular to a multifunctional power monitoring device. Background Technology
[0002] Power systems contain numerous nonlinear, impulsive, and fluctuating loads, such as high-power frequency converters and drive devices, electrified railways, rectifier equipment in the electrochemical industry, induction heating furnaces, and electric arc furnaces. These loads cause waveform distortion (harmonics), voltage fluctuations, flicker, three-phase imbalance, and asymmetry in the power grid, resulting in a significant deterioration in power quality. Simultaneously, the widespread use of computer-based, microprocessor-controlled precision electronic instruments in national economic enterprises has led to increasing sensitivity to power quality and higher demands on power quality. Consequently, power quality issues and their solutions have gradually become a research hotspot. To improve power grid power quality, accurate detection and analysis of power quality are essential. This involves measuring the power quality level of the grid and analyzing and determining the causes of various power quality problems, providing a basis for power quality improvement. Currently, the main method for monitoring power quality both domestically and internationally is online monitoring.
[0003] Chinese Patent Publication No. CN221553624 U discloses a power quality monitoring device. By setting up a fixing component, it solves the problem of triangular support structures occupying a large amount of space inside the power cabinet, reducing the space utilization efficiency of the electrical cabinet. The base plate is fixedly installed inside the cabinet through the threaded holes of the fixing plate. The fixing plate is vertically set and has a small volume, thus occupying less space inside the cabinet and not compressing the space of other electrical components, improving the space utilization efficiency of the electrical cabinet. Thanks to the cooperation of T-shaped blocks and T-slots, the device is initially fixed, and it is easy to remove the device from the fixing component for maintenance and replacement. Through the setting of the limiting component, after the T-shaped block enters the T-slot, the vertical rod of the limiting component is inserted into the limiting hole in the T-shaped block to complete the fixing of the device. The overall integrity of the fixing component and the device is stronger, improving the stability between the device and the fixing component. Furthermore, the device will not slip when the mounting holes of the device are tightened in the next step, facilitating the next installation step.
[0004] The aforementioned technology has a closed structure, which makes inspection and maintenance inconvenient and makes it difficult to effectively dissipate heat from the internal circuit components. Although the button protection component can protect the buttons, the use of multiple buttons in the same row increases the risk of accidental activation. Therefore, this utility model discloses a multifunctional power monitoring device to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a multifunctional power monitoring device to solve the problems mentioned in the background art, such as the traditional power monitoring equipment having a closed structure, which makes inspection and maintenance inconvenient, makes it difficult to achieve effective heat dissipation of internal circuit components, and although the button protection component can protect the buttons, the use of multiple buttons in the same row increases the risk of accidental contact.
[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems:
[0007] A multifunctional power monitoring device includes a chassis with a multifunctional door hinged to one side. The upper part of the multifunctional door has a display window and multiple operation windows. Protective components are installed on the outer side of each operation window and on the multifunctional door. A brushless fan is fixedly embedded in the lower part of the multifunctional door. Multiple air vents are densely distributed on both sides of the chassis. Multiple wire grooves are opened on the front bottom of the chassis.

When the plastic cover is sleeved on the outer periphery of the column, the locking protrusion and the locking block are interference-fitted.
[0009] As a further embodiment of this utility model, the positioning component includes a sliding groove located on both sides of the groove and an elastic plate located on both sides of the baffle. A plurality of first convex circles are equidistantly arranged on the sliding groove, and a second convex circle is arranged on the side of the elastic plate away from the baffle. The second convex circle is limited within the gap between adjacent first convex circles.
[0010] As a further embodiment of this utility model, an arc-shaped groove is provided on one side of the baffle, and grooves are provided on both other sides of the baffle, with one side of the groove being fixed to the elastic plate.
[0011] As a further embodiment of this utility model, perforated mounting plates are fixed at all four corners of the chassis.

[0026] The present invention will be further described below with reference to the embodiments.
[0027] Please see Figure 1-6 This utility model provides a multifunctional power monitoring device, including a chassis 1, wherein a perforated mounting plate 13 is fixed at each of the four corners of the chassis 1;
[0028] Specifically, the perforated mounting plate 13 makes it easier to fix and install the chassis 1. The chassis 1 can be fixed to the wall or bracket with screws through the holes on the perforated mounting plate 13 to achieve stable installation.
[0029] Furthermore, a multi-functional door 2 is hinged to one side of the chassis 1. A display window 21 and multiple operation windows 22 are provided on the upper part of the multi-functional door 2. A display and multiple power monitoring elements are fixed inside the chassis 1 with screws. The display window 21 is positioned opposite to the display, and the operation windows 22 are positioned opposite to the buttons of the power monitoring elements.
[0030] Specifically, the display is located inside the chassis 1 and interacts with the outside through the display window 21. The display window 21 is designed to display power monitoring data, so that the operator can keep track of the working status and monitoring results of the power monitoring device in real time. The operator can control each power monitoring element by lifting the plastic cover 32 and pressing the control button of the power monitoring element.
[0031] Furthermore, a sealing strip 211 is provided inside the display window 21, and a limiting groove with the same thickness as the display window 21 is provided around the sealing strip 211;
[0032] Specifically, ensure that the sealing strip 211 is correctly installed inside the display window 21 and that the sealing strip 211 is in contact with the display to seal the contact surface, so that air does not leak out from the gap between the display window 21 and the display.
[0033] Furthermore, protective components 3 are installed on the outer side of the operation window 22 and on the multi-functional door 2. The protective components 3 include a column 31 fixed to the edge of the operation window 22, a plastic cover 32 hinged to the multi-functional door 2, and a locking block 33 fixedly connected to the multi-functional door 2. A sealing ring 34 is fixedly sleeved on the inner edge of the plastic cover 32. The plastic cover 32 and the locking block 33 are located on both sides of the column 31. A locking protrusion 321 is fixed on the edge of the plastic cover 32. When the plastic cover 32 is sleeved on the outer side of the column 31, the locking protrusion 321 and the locking block 33 are interference fit.
[0034] Specifically, the plastic cover 32 is hinged to the multi-functional door 2, allowing for easy opening and closing to protect the control buttons of the power monitoring element inside the operating window 22. The sealing ring 34 is fixedly fitted onto the inner edge of the plastic cover 32. When the plastic cover 32 is closed, the sealing ring 34 provides a sealing effect, preventing dust, moisture, or other impurities from entering the operating window 22 and protecting the control buttons from damage. Furthermore, the latch 321 and the latch block 33 are interference-fitted to ensure that the plastic cover 32 can be securely fixed to the column cylinder 31 in the closed state, preventing accidental opening and preventing damage to the control buttons from misoperation and environmental factors.
[0035] Furthermore, a brushless fan 4 is fixedly embedded in the lower part of the multi-functional door 2, wherein multiple air holes 11 are densely distributed on both sides of the chassis 1;
[0036] Specifically, the main function of the brushless fan 4 is to provide active cooling. Through the operation of the fan, the heat generated inside the chassis 1 can be effectively dissipated, keeping components such as the power monitoring element and the display at a suitable temperature, thereby improving the stability and lifespan of the entire power monitoring device. The densely packed air vents 11 on both sides of the chassis 1, combined with the brushless fan 4, form an effective airflow path. The design of the air vents 11 helps the fan draw in cool air and expel hot air from inside the chassis 1, achieving good heat exchange. Embedding the brushless fan 4 in the lower part of the multi-functional door 2 maximizes the use of the internal space of the chassis 1 while maintaining the compact design of the chassis, making the entire device look neat and fully functional.
[0037] Furthermore, a plurality of wire grooves 12 are provided on the bottom front side of the chassis 1, and a baffle 5 is embedded in each wire groove 12. An arc groove 51 is provided on one side of the baffle 5, and grooves 52 are provided on the other two sides of the baffle 5. One side of the groove 52 is fixed to the elastic plate 62.
[0038] Specifically, the arc groove 51 helps to bend and fix the cable, reducing damage to the cable. The elastic plate 62 is elastic and can retract into the groove 52 when it is pressed by an external force, so that the baffle 5 can slide in a straight line along the groove 61.
[0039] Furthermore, adjacent baffles 5 and wire grooves 12 are connected by positioning components 6. The positioning components 6 include sliding grooves 61 on both sides of wire grooves 12 and elastic plates 62 on both sides of baffles 5. Multiple first convex circles 611 are equidistantly arranged on the sliding grooves 61. A second convex circle 621 is arranged on the side of the elastic plate 62 away from the baffles 5. The second convex circle 621 is limited in the gap between adjacent first convex circles 611.
[0040] Specifically, the cooperation of the first convex circle 611 and the second convex circle 621 can be used to limit the movement range of the elastic plate 62, ensuring that the elastic plate 62 can fix the cable in the correct position. The baffle 5 can be firmly fixed in the wire groove 12 to prevent the cable from accidentally falling off or moving, thereby ensuring the stability and safety of the internal circuit of the power monitoring device.
[0041] Working principle: During use, the cable passes through the cable tray 12 and exits the chassis 1 to connect to the power transmission equipment. The baffle 5 is embedded in the cable tray 12, and the second convex circle 621 is limited in the gap between the adjacent first convex circle 611, which can prevent the baffle 5 from sliding in the opposite direction and play the role of clamping and limiting the cable, avoiding the messy cable arrangement. After closing the multi-function door 2, the display extends out of the display window 21, which makes it easy for the operator to grasp the power monitoring data. Lifting the plastic cover 32 and pressing the control button of the power monitoring element can control the opening and closing of each power monitoring element, avoiding the danger of accidental contact. At the same time, the brushless fan 4 is powered on and runs, which can draw cold air into the chassis 1. After heat exchange, the air is discharged outward from each air hole 11, which can reduce the operating heat of the display and power monitoring elements and avoid the risk of overheating.
