Description

Technical Field

[0001] This utility model relates to the field of reactive power integrated measurement and control technology, and more specifically, to a low-voltage reactive power integrated measurement and control device. Background Technology

[0002] The low-voltage reactive power integrated measurement and control device is a piece of equipment used in low-voltage power systems. It is mainly used to monitor, measure and compensate reactive power in the system. Reactive power is a type of power generated in AC circuits. It together with active power constitutes the total power. The measurement and control device can monitor the three-phase voltage, current, power, power factor, harmonics and other operating data of the power grid in real time. It realizes human-machine interaction through an LCD screen. It can complete the comprehensive management of the entire low-voltage distribution line, including real-time monitoring, data analysis, report processing, etc., and monitor and display the operating status and switching status of intelligent capacitors.

[0003] Chinese Patent Publication No. CN216981526U discloses an intelligent measurement and control device for reactive power compensation. A rubber suction cup is fixedly installed on the rear side of the device, and a magnetic suction plate is fixedly installed on the inner wall of the heat dissipation cavity corresponding to the position of the rubber suction cup. An upper elastic strap and a lower elastic strap are provided in the rectangular groove of the outer ring of the device. The entire device can be fixed to the surface of an external machine by adsorption with the rubber suction cup, or it can be fixed to a suitable position on the external machine using the upper and lower elastic straps. This facilitates compatibility with various devices, has a wide range of applications, eliminates the need for individual customization, allows for mass production, and saves production time and costs.

[0004] The reactive power integrated measurement and control device needs to work continuously during use, and there are many electrical devices around it, which leads to high ambient temperature. The device in the above solution does not have a corresponding active heat dissipation function. When working in a hot environment for a long time, heat will easily accumulate inside, which will affect its performance and lifespan. At the same time, the continuous high temperature environment will easily cause the aging and damage of the equipment components, ultimately leading to equipment failure.

[0005] Therefore, it is necessary to provide a low-voltage reactive power integrated measurement and control device to solve the above problems. Utility Model Content

[0037] The reactive power integrated measurement and control device needs to work continuously during use. At the same time, there are many electrical devices around it, which leads to a high ambient temperature. Without corresponding active heat dissipation function, it is easy to accumulate heat inside the device when working in a hot environment for a long time, which will affect its performance and lifespan. In addition, the continuous high temperature environment can easily cause aging and damage to the device components, ultimately leading to equipment failure.

[0038] Based on this, it is possible to improve the lack of corresponding active heat dissipation functions in related technologies, which prevents the equipment from operating within a suitable temperature range and thus fails to improve the performance and stability of the equipment.

Multiple wiring interfaces 9 are installed at the bottom of the measurement and control device body 2. These wiring interfaces 9 are mainly used to connect to lines and intelligent capacitor devices, enabling them to provide data and communication connections to the measurement and control device body 2. The measurement and control device body 2 is... It mainly consists of sensors and measuring devices, a controller, a communication module, and a power supply module.

[0042] A heat dissipation hole 7 is provided on one side of the main body 2 of the measurement and control device. A heat dissipation component 6 is installed on the side away from the heat dissipation hole 7. A ventilation component 5 is installed at the outer end of the heat dissipation component 6. The heat dissipation component 6 mainly blows air into the main body 2 of the measurement and control device through the cooling fan 63, while the ventilation component 5 is mainly used to allow air to enter. The cooperation of the ventilation component 5 and the heat dissipation component 6 can achieve active heat dissipation, helping the equipment to work within a suitable temperature range, thereby improving the performance and stability of the equipment. An adjustment component 8 is installed at the outer end of the ventilation component 5. A ventilation hole 82 is opened on the rotating collar 81 to connect the inside of the ventilation component 5 with the outside. By adjusting the position between the connecting block 52 and the baffle 55, the air intake can be adjusted. By adjusting the air intake, the heat dissipation effect of the equipment can be controlled more precisely.

[0043] Optionally, in some embodiments, please refer to Figures 4-6 The ventilation assembly 5 also includes a connecting ring 51. The outer end of the connecting ring 51 is fixedly connected to the housing 61. A plurality of connecting blocks 52 are fixedly connected to the side of the connecting ring 51 away from the housing 61 in an annular and equidistant arrangement. A fixing plate 53 is fixedly connected to the outer end of the connecting block 52. The connecting block 52 is located between the connecting ring 51 and the fixing plate 53.

[0044] The outer end of the mounting plate 54 abuts against the fixing plate 53, and the side of the baffle 55 away from the mounting plate 54 is fixedly connected to the edge of the connecting ring 51.

[0045] In this design, the ventilation component 5 is mainly installed on the outer end of the heat dissipation component 6. The housing 61 is fixed to the outer end of the measurement and control device body 2, and the interior of the housing 61 is connected to the interior of the measurement and control device body 2. An air inlet is also provided on the other side of the housing 61, making both sides of the housing 61 interconnected. Inside the housing 61, a mounting frame 62 is fixed, and a cooling fan 63 is installed inside the mounting frame 62. The cooling fan 63 mainly consists of fan blades and a motor. By rotating, it draws external air into the measurement and control device body 2, and then the air is discharged through the heat dissipation hole 7, actively cooling the interior of the measurement and control device body 2. The connecting ring 5... 1 is fixed to the outside of the housing 61. A ring of connecting blocks 52 is provided between the connecting ring 51 and the fixing plate 53, distributed along the edge, so that ventilation is possible. An installation plate 54 is provided at the outer end of the fixing plate 53. Four arc-shaped baffles 55 are fixed at the outer end of the installation plate 54, so that the baffles 55 can fit tightly with the connecting blocks 52. The outer end of the baffles 55 is fixedly connected to the edge of the connecting ring 51, thereby blocking the gap between the connecting blocks 52 and forming a fixed ventilation channel for use with the adjustment component 8 to adjust the air volume. At the same time, filters can also be used in the gaps between the multiple baffles 55 to reduce dust from entering the interior of the measurement and control device body 2.

[0046] Optionally, in some embodiments, please refer to Figures 5-7 The adjusting component 8 includes a rotating collar 81, which is sleeved around the baffle 55. The rotating collar 81 is located between the mounting plate 54 and the connecting ring 51, and the two sides of the rotating collar 81 are rotatably connected to the outer ends of the mounting plate 54 and the connecting ring 51, respectively.

[0047] The outer end of the rotating collar 81 has multiple ventilation holes 82, the number of which corresponds to the number of baffles 55. The outer end of the rotating collar 81 is fixedly connected to a mounting block 83, and the outer end of the mounting block 83 is fixedly connected to a movable block 84.

[0048] The adjustment component 8 also includes a limiting block 86. A telescopic spring 85 is provided inside the movable block 84. The limiting block 86 is slidably connected to the inner side wall of the movable block 84. One end of the telescopic spring 85 is fixedly connected to the limiting block 86. Multiple limiting grooves 56 are provided at the outer end of the mounting plate 54 in an annular and equidistant arrangement. The limiting block 86 abuts against the limiting grooves 56.

[0049] The adjusting component 8 in this solution mainly covers the air inlet of the ventilation component 5, limiting the air intake by adjusting the covering area. Since the connecting ring 51 and the mounting plate 54 have the same diameter and are both larger than the fixed plate 53, the rotating collar 81 will be locked between the mounting plate 54 and the connecting ring 51, fitting around the baffle 55. Four ventilation holes 82 are provided on the rotating collar 81. By rotating the rotating collar 81, when the ventilation holes 82 coincide with the gaps between the two baffles 55, the passage can be fully opened; otherwise, the air intake can be reduced. A mounting block 83 is fixed to the outer end of the rotating collar 81, and a movable block 84 is fixed on the mounting block 83. The movable block 84 is equipped with a telescopic spring 85 and a limiting block 86. The telescopic spring 85 pushes the limiting block 86 outward by its own force. Since a limiting groove 56 is opened at the edge of the mounting plate 54, when the limiting block 86 is pushed outward by the force of the telescopic spring 85, the limiting block 86 can abut against the limiting groove 56, thereby achieving the function of limiting the rotating collar 81 and preventing it from rotating on its own after the position is adjusted.

[0050] Working principle: When using this device, the relevant parameters can be viewed and set by using the button 4 on the top cover plate 1 and the display screen 3. A heat dissipation hole 7 is provided on one side of the main body 2 of the measurement and control device, and a heat dissipation component 6 is installed on the side away from the heat dissipation hole 7. A cooling fan 63 is installed inside the mounting frame 62. By rotating, external air can be drawn into the main body 2 of the measurement and control device, and then the air will be discharged from the heat dissipation hole 7, thus actively dissipating and cooling the inside of the main body 2 of the measurement and control device. The connecting ring 51 is fixed to the outside of the housing 61, and the outer end of the baffle 55 is fixedly connected to the edge of the connecting ring 51, thereby blocking the gap between the connecting blocks 52 and forming a fixed ventilation channel. The rotating collar 81 is fitted around the baffle 55. By rotating the rotating collar 81, when the ventilation hole 82 coincides with the gap between the two baffles 55, the channel can be fully opened; otherwise, the air intake can be reduced.

[0051] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
