Description

Technical Field

[0001] This invention belongs to the field of power distribution boxes, and in particular relates to an intelligent power distribution box with real-time monitoring function. Background Technology

[0002] With the rapid development of industrial automation, intelligent buildings, and data centers, the requirements for the reliability and stability of power supply systems are increasing. As the core equipment for power distribution and control, the distribution cabinet integrates various high-power heat-generating components such as circuit breakers, contactors, frequency converters, and smart meters. Traditional distribution cabinets suffer from significant heat dissipation problems during long-term operation, especially under conditions of heavy load or high ambient temperature, becoming a key bottleneck affecting equipment lifespan, operational safety, and energy efficiency.

[0003] Existing power distribution cabinet heat dissipation designs often suffer from the following significant defects: First, they generally rely on natural ventilation, resulting in chaotic airflow organization and an inability to provide differentiated and precise airflow to multiple independent zones within the cabinet (such as compartments for devices of different power levels). This leads to insufficient heat dissipation in high-heat-density areas, easily forming localized hot spots, accelerating the aging of insulation materials, causing component performance degradation, and even malfunctions. Second, when using natural ventilation for heat dissipation, moisture in the air can enter the cabinet. Moisture adhering to the surface of energized electrical components (such as circuit breakers and terminals) significantly reduces their insulation performance. This can easily cause arcing or short circuits between conductors at different potentials, leading to equipment malfunctions, damage, or even fires. Summary of the Invention

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0021] Please see Figure 1 and 6 As shown, this invention is an intelligent distribution box with real-time monitoring function, comprising a cabinet 2 and a top cover 1 installed on the top of the cabinet 2; the cabinet 2 is divided into four independent equipment chambers 20 by partitions 21 with openings, and a monitoring system is installed inside the cabinet 2. The monitoring system includes a main control unit, which is connected to an electrical parameter monitoring module, a multi-sensor module, an intelligent protection device, and a communication module; the electrical parameter monitoring module, the multi-sensor module, the intelligent protection device, and the communication module are respectively installed in the four equipment chambers 20; the main control module is configured to process the data collected by the electrical parameter monitoring module and the multi-sensor module, upload it to a remote management platform through the communication module, and control the intelligent protection device to operate according to a preset safety policy or instructions from the remote management platform, thereby realizing fault early warning, remote operation and maintenance, and precise protection.

[0022] As mentioned above, the electrical parameter monitoring module, multi-sensor module, intelligent protection device, and communication module installed in the equipment cavity 20 will generate heat during long-term operation. Therefore, heat dissipation needs to be considered in actual use to avoid the equipment cavity 20 being in a high-temperature state. Furthermore, since the heating effect of electrical components in each equipment cavity 20 is different, the heat dissipation performance required for each equipment cavity 20 is different in actual use. Each equipment cavity 20 with a high temperature needs better heat dissipation performance, while each equipment cavity 20 with a low temperature has lower requirements for heat dissipation performance.

[0023] In use, a fan 134 is installed in a main air duct 13 and connected to four branch air ducts 14 at the outlet end of the main air duct 13; each equipment cavity 20 has an air inlet hole on its side wall that connects to the outlet end of the branch air duct 14. In other words, in actual use, the fan 134 sends the ambient air into the corresponding equipment cavity 20 through the cooperation of the main air duct 13 and the branch air ducts 14 to complete the cooling.

[0024] Since ambient air generally contains a certain amount of moisture and is affected by ambient temperature, when both the ambient temperature and humidity are high, simply introducing ambient air into the cabinet will not only fail to achieve good cooling, but will also introduce ambient moisture into the cabinet. Based on this, the present invention forms a condensing chamber 10 inside the top cover 1. The condensing chamber 10 is equipped with an evaporator 11 of a refrigeration system. In addition to the evaporator 11, the refrigeration system also includes a compressor, condenser, etc. An air inlet 14 is opened on the side wall of the condensing chamber 10, and an exhaust structure 5 is installed inside the condensing chamber 10. The exhaust end of the exhaust structure 5 is connected to the main air duct 13. When the fan 134 is started, the fan 134 acts as a power source, and the ambient air enters the condensing chamber 10 through the air inlet 14. Under the action of the evaporator 11, the ambient air is cooled and moisture is extracted. The cooled ambient air is then sent into the corresponding equipment cavity 20 through the cooperation of the main air duct 13 and the branch air duct 14 to complete the cooling. The extracted moisture remains in the condensing chamber 10.

[0025] The multi-sensor module includes multiple temperature sensors and a leakage current detection sensor. The temperature sensors are used to detect the temperature within each equipment cavity 20 of the enclosure. The electrical parameter monitoring module also includes a harmonic analysis unit for monitoring the harmonic content and distortion rate in the power grid, and a high-precision voltage / current sensor for real-time acquisition of voltage, current, power, and power factor in the power distribution circuit. The communication module supports multi-mode communication, including at least two of 4G / 5G cellular networks, Ethernet, and LoRa wireless communication. The intelligent protection device includes a programmable intelligent circuit breaker and / or a residual current operated protector with communication function, whose protection threshold can be remotely set and adjusted through the main control module or remote management platform.

[0026] In use, to adjust the airflow into each equipment cavity 20 based on the monitored temperature, thereby achieving roughly the same heat dissipation effect across multiple equipment cavities 20 at different temperatures and ensuring that the temperature within each equipment cavity 20 meets specifications; based on this, if Figure 8The main air duct 13 provided by the present invention includes a gradually expanding shell 132. An air inlet pipe 131 and an end plate 133 are respectively installed at the narrow end and the wide end of the shell 132. Multiple exhaust pipes 135 are connected to the end plate 133, and each exhaust pipe 135 is connected to a branch air duct 14. A fan 134 is installed inside the air inlet pipe 131 as a power source for air supply. The low-temperature dry air after cooling and dehumidification is transported to each independent equipment cavity 20 in the cabinet 2 through the main air duct 13 and the branch air duct 14 under the drive of the fan 134. A sealing plate 1361 is provided in the shell 132 at the end of each exhaust pipe 135 to seal the end of the exhaust pipe 135. During use, the air volume is adjusted by controlling the distance between the sealing plate 1361 and the end face of the exhaust pipe 135. When the sealing plate 1361 and the exhaust pipe 135 are reduced, the air volume entering the exhaust pipe 135 decreases. The use of a gradually expanding shell 132 design can effectively reduce airflow speed, convert dynamic pressure into static pressure, and make the airflow more smoothly distributed to each exhaust pipe 135. This helps to reduce airflow resistance loss and noise, and ensures that each branch duct 14 can obtain relatively uniform air pressure.

[0027] In other words, based on the above, to facilitate adjustment of the distance between the sealing plate 1361 and the exhaust pipe 135, a first guide frame 1351 is fixed to the inner wall of the exhaust pipe 135. A first movable rod 136 is installed through the first guide frame 1351. The top of the first movable rod 136 is connected to the sealing plate 1361, which can seal the end of the exhaust pipe 135. The top of the sealing plate 1361 is connected to the connecting rod 1362. The inner wall of the shell 132 located directly above any exhaust pipe 135 is connected to an inverted cylinder 137 through a connecting column. A first electromagnet 138 is installed on the inner bottom side of the cylinder 137. The end of the connecting rod 1362 is connected to a piston 1363 that slides along the inner wall of the cylinder 137. A first magnet is installed inside the piston 1363. During use, the first electromagnet 138 is energized and its magnetic strength is controlled according to the temperature inside the equipment cavity 20. The magnetic strength of the first electromagnet 138 is then adjusted by the repulsive force between the first magnet and the first electromagnet 138. When the first electromagnet 138 is energized, the piston 1363 is driven to slide along the inner wall of the cylinder 137 under the combined action of the magnetic field and air pressure, thereby adjusting the distance between the sealing plate 1361 and the exhaust pipe 135.

[0028] To facilitate the delivery of cool air to both sides of the cabinet 2 and to facilitate the arrangement of the main air duct 13 and branch air duct 14, a mezzanine is provided inside the side panels on both sides of the cabinet 2; a set of main air duct 13 and branch air duct 14 are installed in each of the two mezzanines; at the same time, air inlets 14 are opened on the opposite side walls of the condensation chamber 10; at this time, in order to facilitate the control of the ambient air being cooled and then delivered into the cabinet; such as Figure 9The provided exhaust structure 5 includes a horizontal pipe 5 horizontally arranged on the bottom side of the condensing chamber 10. The two ends of the horizontal pipe 5 are respectively connected to the air inlet pipes 131 of the two main air ducts 13. A convex pipe 51 is arranged in the middle of the top side of the horizontal pipe 5. The top side of the horizontal pipe 5 located around the convex pipe 51 is connected to a support column 52. The end of the support column 52 is connected to a waterproof cover 53. The waterproof cover 53 covers the top of the convex pipe 51. The waterproof cover 53 is arranged to prevent water droplets on the evaporator 11 from dripping into the convex pipe 51. The exhaust structure 5 is located directly below the evaporator 11. The convex pipe 51 is located in the lower middle section of the condensing chamber 10. At this time, the ambient air entering the condensing chamber 10 through the air inlet 14 converges from both sides to the middle. The convergence process is cooled by the action of the evaporator 11.

[0029] In actual use, with long-term use, the condensation chamber 10 will accumulate a large amount of condensate. If this condensate is not drained in time, it may overflow. A downwardly recessed water storage chamber 12 is provided at both ends of the bottom of the condensation chamber 10. The height of the inner bottom side of the condensation chamber 10 gradually decreases from the middle to the sides, which facilitates the collection of condensate by the water storage chambers 12 on both sides. The bottom side of the water storage chamber 12 is connected to a flexible tube.

[0030] To improve the heat dissipation effect inside the cabinet 2, the present invention installs a water-cooling mechanism 3 on the outer wall of the cabinet 2. The water-cooling mechanism 3 is in close contact with the outer wall of the cabinet 2. The drain pipe 121 at the bottom of the water storage chamber 12 is connected to the water-cooling mechanism 3 installed on the outer wall of the cabinet 2 through a flexible hose. The water-cooling mechanism 3 provides auxiliary heat dissipation for the cabinet, thereby improving the overall heat dissipation efficiency and realizing the recycling of energy.

[0031] Specifically, such as Figure 10-12 The water-cooling mechanism 3 consists of a U-shaped enclosure 31, a U-shaped side panel 32, and the outer wall of the cabinet 2, forming a water storage tank 33 and an installation cavity. A water-absorbing plate 35 is installed inside the installation cavity, flush against the wall of the cabinet 2, with its bottom immersed in the water storage tank 33. A rectangular groove 351 is formed on the top of the water-absorbing plate 35. A water-filling box 36 is fixed to the top of the U-shaped enclosure 31, with a water inlet connector 37 connected to the top of the water-filling box 36. Multiple water outlet pipes 360 extend into the rectangular groove 351 from the bottom of the water-filling box 36. Through capillary action, condensate is continuously absorbed onto the entire water-absorbing plate 35, keeping it moist. The moist water-absorbing plate 35 comes into contact with the air, and the moisture on its surface continuously evaporates. During evaporation, the water absorbs a large amount of heat, which comes directly from the cabinet 2 wall in close contact with the water-absorbing plate 35, effectively reducing the surface temperature of the cabinet 2 and achieving auxiliary heat dissipation for the interior.

[0032] The water-absorbing plate 35 includes a metal mesh in the middle, with water-absorbing layers on both sides of the metal mesh; the water-absorbing layers are made of sponge or cotton cloth; the bottom side of the water injection box 36 has a cloth layer 361, a filler layer 362 and a porous pressure plate 363 arranged from bottom to top; the filler layer 362 is an ion exchange resin filler layer, which can remove calcium and magnesium ions in the water, prevent scale and blockage on the water-absorbing plate 35, and affect the water absorption of the water-absorbing plate 35 and thus affect the heat dissipation effect of the water-absorbing plate 35; the cloth layer 361 can reduce the flow rate of water through the outlet pipe 360, and prevent splashing caused by high-speed flow from the outlet pipe 360.

[0033] In actual operation, in order to facilitate the control of water outflow from the water storage chamber 12, the water is controlled to flow into the corresponding water cooling mechanism 3 according to demand; such as Figure 5-7 The bottom side of the water storage chamber 12 of this invention is connected to a drain pipe 121. A second guide frame 122 is fixed to the inner wall of the drain pipe 121. A second movable rod 171 is inserted through the second guide frame 122. The top of the second movable rod 171 is connected to a sealing plate 137 that can seal the end of the drain pipe 121. A support plate 15 is provided on the inner wall of the condensation chamber 10 located directly above the water storage chamber 12. The support plate 15 is installed below the air inlet 14. A side mounting plate 151 is provided on the upper surface of the support plate 15. A horizontal telescopic member 152 is installed on one side of the mounting plate 151. The end of the telescopic member 152 is connected to a vertical rod 153. The end of the vertical rod 153 is connected to a second magnetic block 16. A third magnetic block is embedded in 137, and the third magnetic block and the second magnetic block 16 attract each other; a rectangular hole 154 is opened on the support plate 15 for the vertical rod 153 to pass through and to match its movement path. A triangular sealing fin 155 is provided on the adjacent side walls of the rectangular hole 154; when it is necessary to control the water in the water storage chamber 12 to flow into the corresponding water cooling mechanism 3, the telescopic member 152 is controlled to extend and retract, driving the second magnetic block 16 to move directly above the corresponding third magnetic block. At this time, under the attraction of the third magnetic block and the second magnetic block 16, the sealing plate 137 moves upward until it detaches from the bottom side of the water storage chamber 12, thus opening the drainage passage. At this time, the water in the water storage chamber 12 flows into the corresponding water cooling mechanism 3.

[0034] When the vertical rod 153 moves horizontally under the drive of the telescopic member 152, the hypotenuse of the triangle can form a line contact or narrow surface contact with the surface of the vertical rod 153; this design allows the sealing fins 155 to undergo elastic deformation and fit tightly against the surface of the vertical rod 153, preventing the ambient air entering the condensation chamber 10 through the air inlet 14 from passing through the rectangular hole 154.

[0035] like Figure 1-2To facilitate the hoisting of cabinet 2, a hanging mechanism 4 is fixed on both sides of the top of cabinet 2. The hanging mechanism 4 includes a "Z"-shaped connecting plate 41 welded and fixed to the end face of the top cover 1. The connecting plate 41 has a rectangular opening 44 that coincides with the air inlet 14. The top of the connecting plate 41 is provided with a hanging hole 42 and a hanging ring 45. An L-shaped side reinforcing plate 43 is provided on the outside of the connecting plate 41. The side reinforcing plate 43 is perpendicular to the connecting plate 41. The hanging hole 42 and the hanging ring 45 are designed to facilitate hoisting and handling.

[0036] To filter the ambient air entering the condenser chamber 10 from the air inlet 14, a filter assembly 6 is detachably installed at the air inlet 14. Before the ambient air is drawn in and flows through the evaporator 11 of the refrigeration system for cooling and dehumidification, the filter assembly 6 first filters the air. This effectively blocks larger particulate pollutants such as dust, catkins, and insects from entering the system. This primary filtration is crucial; it prevents dust accumulation on the surface of the evaporator 11 from affecting heat exchange efficiency, and also prevents impurities from entering the subsequent main air duct 13, branch air duct 14, and the equipment cavity 20 inside the cabinet 2, thereby protecting precision electrical components and ensuring the long-term stable and efficient operation of the entire heat dissipation and monitoring system.

[0037] When used for a long time, such as Figure 3-4 The filter assembly 6 accumulates a lot of dust. To facilitate the removal and cleaning of the filter, and because the side reinforcing plate 43 obstructs the air inlet 14, the presence of the side reinforcing plate 43 interferes with the installation and disassembly of the traditional integrated filter assembly 6. The filter assembly 6 provided by the present invention includes a first side panel 60 and a second side panel 61 arranged opposite to each other. An upper support beam 62 and a lower support beam 63 are connected between the first side panel 60 and the second side panel 61. Multiple filter units 64 are detachably installed in the space formed by the first side panel 60, the second side panel 61, the upper support beam 62 and the lower support beam 63. The second side panel 61 is arranged on the side closer to the first side panel 60. A rectangular channel has a movable side plate 65 connected to its bottom side via an elastic telescopic sleeve. A locking bolt 66 is threaded onto the second side plate 61. The top and bottom of the filter unit 64 are respectively provided with a first sliding groove 642 and a second sliding groove 641. The distance from the bottom side of the first sliding groove 642 to the bottom side of the filter unit 64 is L1, and the distance between the upper support beam 62 and the lower support beam 63 is L1+L2. The distance from the bottom side of the second sliding groove 641 to the bottom top of the filter unit 64 is L3. Therefore, L1+L2 is between L1 and L3, and L3>L1. The filter unit 64 adopts a detachable modular design and is installed between the upper support beam 62 and the lower support beam 63. When the filter becomes clogged with dust due to long-term use, maintenance personnel can easily remove it for cleaning or replacement, ensuring continuous filtration effect and making maintenance simple and quick.

[0038] The assembly process of filter assembly 6 includes: aligning the top groove 642 of filter unit 64 with the upper support beam 62 and the bottom groove 641 with the lower support beam 63, and then pushing them in; after all filter units 64 are placed, loosening the locking bolt 66, at which point the movable side plate 65 located in the rectangular groove of the second side panel 61 will naturally move towards the first side panel 60 under the action of the elastic telescopic sleeve rod on its back, thereby pressing the filter unit 64 on this side, and tightening the locking bolt 66 threaded on the second side panel 61. The end of the locking bolt 66 will press against the movable side plate 65, further pressing it, thereby firmly fixing all filter units 64 within the frame.

[0039] The overall process of heat dissipation in the power distribution cabinet of this invention includes: Ambient air enters through the air inlets 14 on both sides of the condenser chamber 10, and first passes through the filter assembly 6 to filter dust and impurities; then, the air flows through the evaporator 11 of the refrigeration system, is forced to cool down and release moisture, forming low-temperature dry air. Low-temperature dry air is collected by the exhaust structure 5 located directly below the evaporator and, driven by the fan 134, is precisely delivered into each independent equipment cavity 20 inside the cabinet 2 through the main air duct 13 and the branch air duct 14 to efficiently dissipate heat from the internal electrical components; the air volume can be intelligently adjusted according to the temperature feedback of each equipment cavity.

[0040] The condensate generated during the cooling and dehumidification process flows into the water storage chamber 12 along the inclined surface of the condensation chamber 10. This condensate is guided to the water cooling mechanism 3 installed close to the outer wall of the cabinet 2 through a controllable drainage mechanism. The water cooling mechanism uses the capillary action of the water absorption plate 35 to keep it moist, and the surface water evaporates to absorb the heat of the cabinet, thereby achieving auxiliary heat dissipation for the cabinet 2.
