Description

Technical Field

[0001] This invention relates to the field of switchgear technology, and in particular to a high-reliability high-voltage switchgear. Background Technology

[0002] A switchgear is a complete set of electrical equipment used in power systems for centralized control, protection, and distribution of circuits. It integrates components such as circuit breakers, contactors, transformers, and protection devices. Its main functions are to realize circuit connection, disconnection, overload protection, short circuit protection, and leakage protection, while facilitating inspection and maintenance and ensuring safe, stable, and reliable power supply operation.

[0003] Chinese patent application number CN202511459107.7 discloses a high-efficiency heat dissipation switch cabinet, including: a main body and a first component installed thereon. The first component includes: a positioning shell that assists in the installation of subsequent components. The positioning shell has a through groove in the middle and side chambers at the four corners of the positioning shell cavity. A honeycomb plate A is slidably connected inside the positioning shell. By setting up a water collection cavity, rainwater is collected, which not only triggers moisture protection, but also, during rainless periods, the rainwater stored in the water collection cavity can cooperate with the heat dissipation fins and honeycomb plate A in the main body to form a heat exchange circuit. After the heat inside the main body rises, it comes into contact with the heat dissipation fins. The honeycomb plate A and honeycomb plate B above the main body use the high thermal conductivity of the honeycomb structure to transfer the heat absorbed by the fins to the rainwater. The heat is carried away by the natural evaporation of the rainwater. By utilizing the specific heat capacity of rainwater, the heat dissipation capacity is enhanced during rainless periods without consuming additional energy.

[0004] In operation, the aforementioned patent requires that the heat dissipation vents of the switch cabinet be closed during rainy weather to prevent rainwater from entering the cabinet. At this time, the heat generated inside the cabinet cannot be dissipated and will continue to accumulate, causing the internal temperature to rise continuously. As the temperature rises, the atomic movement inside the electrical components intensifies, causing frequent collisions with the transmission electrons, which hinders electron transmission and increases resistance. With the operating current of the equipment remaining constant, the greater the resistance, the more electrical energy is lost when the current passes through, thus forming a vicious cycle of higher temperature and higher power consumption, resulting in increased power loss of the switch cabinet during operation.

[0005] Therefore, we propose a high-reliability high-voltage switchgear. Summary of the Invention

[0006] The technical problem to be solved by the present invention is that the existing technology has the disadvantage that in order to prevent rainwater and moisture from entering, the heat dissipation vents need to be closed, which makes the heat inside the switch cabinet increasingly higher and higher, ultimately leading to increased power loss when the switch cabinet is working. To this end, we propose a high-reliability high-voltage switch cabinet.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: a high-reliability high-voltage switchgear, including a cabinet, a cooling component for diverting rainwater is fixedly installed on the upper surface of the cabinet, and collection frames are fixedly installed on both sides of the cooling component; The cooling assembly includes a distribution plate fixedly installed on the upper surface of the cabinet. A dehumidifier is installed inside the distribution plate. A distribution pipe is fixedly installed at both ends of the dehumidifier. There are two sets of distribution pipes. A water-cooled pipe is fixedly installed at one end of each of the two sets of distribution pipes. Three sets of water-cooled pipes are installed inside the cabinet. Two sets of dehumidifiers are connected to the collection frame. A connecting pipe is movably installed between the three sets of water-cooled pipes. A heat-absorbing pipe is fixedly installed on the surface of each set of water-cooled pipes. The heat-absorbing pipe is located inside the cabinet.

[0008] Furthermore, all water-cooling pipes are installed at an angle, fitting snugly against the inner wall of the cabinet, and are made of copper.

[0009] Furthermore, a suction pipe is fixedly installed on the lower surface of the dehumidifier. One end of the suction pipe is connected to the inside of the cabinet. The dehumidifier is located inside the distribution plate. The suction pipe can draw moisture from inside the cabinet. The drawn moisture then enters the dehumidifier for conversion, turning the moisture into water, which is then stored inside the dehumidifier.

[0010] Furthermore, a chamber is provided inside the diverter plate, the surface of the diverter plate is coated with a radiation cooling coating, the inner wall of the chamber is lined with polyurethane foam, and the dehumidifier is located inside the chamber.

[0011] Furthermore, a filter plate is movably installed inside the collection frame, a guide rod is fixedly installed at the bottom of the collection frame, a drain port is opened on the lower surface of the collection frame, an isolation plate is movably installed on the inner wall of the drain port, a drain pipe is fixedly installed on the lower surface of the drain port, the drain pipe is connected to a water cooling pipe, a plate groove is opened on the inner wall of the collection frame, two sets of plate grooves are provided, an inner groove is opened inside the collection frame, and a trigger component for opening and closing the isolation plate is movably installed inside the inner groove.

[0012] Furthermore, the triggering component includes a linkage component that is movably disposed inside the inner groove for adapting to the flipping. A sliding plate is movably disposed at one end of the linkage component, and a top plate is movably disposed at the other end of the sliding plate. A protruding post is fixedly installed on both the top plate and one end of the linkage component. The filter plate is located between the two sets of protruding posts. A baffle is fixedly installed on the outer surface of the protruding post, and the protruding post is slidably connected to the plate groove.

[0013] Furthermore, magnetic plates A and B are fixedly installed on the inner wall of the inner tank, and magnetic plate C is fixedly installed on the outer surface of the slide plate. Magnetic plate C is attracted to magnetic plates A and B. When the top plate is in a horizontal state, magnetic plate C is attracted to magnetic plate A, keeping the top plate in a horizontal state.

[0014] Furthermore, the linkage component includes a central rod disposed inside the inner groove, a central plate fixedly disposed on the outer surface of the central rod, limit grooves opened at both ends of the central plate, a telescopic rod fixedly installed on the inner wall of the limit groove, a limit plate fixedly installed at one end of the telescopic rod, and a movable plate fixedly installed at one end of the limit plate.

[0015] Furthermore, a long rod is fixedly installed inside the isolation plate, and a belt is fitted on the outer surface of the long rod and the central rod. The isolation plate is movably connected to the drain port through the long rod.

[0016] Furthermore, a cabinet door is hinged to one side of the cabinet body, and a heat dissipation vent is opened inside the cabinet door. An electric plate is movably installed inside the heat dissipation vent. A rectangular groove is opened inside the cabinet body, which is adapted to the heat absorption pipe. A raindrop sensor is installed on one side of the cabinet body, and the raindrop sensor is located above the cabinet door.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention proposes a high-reliability high-voltage switchgear. When it rains, the electric plate inside the cabinet's heat dissipation vents closes to prevent rainwater from entering. The diversion plate diverts the rainwater, and the collection frame begins collecting it. The filter plate inside the collection frame isolates impurities in the rainwater. As the rainwater accumulates, the filter plate floats up and triggers a triggering component. The linkage component drives the isolation plate to flip, allowing the rainwater to enter the water-cooling pipes through the drain pipe. The connecting pipe fills all three sets of water-cooling pipes with rainwater, allowing the rainwater inside the water-cooling pipes to continuously carry away heat from the cabinet, preventing temperature rise. The heat-absorbing pipes directly absorb heat from the cabinet, further reducing the internal temperature and preventing electrical components from overheating and increasing resistance. Simultaneously, the dehumidifier draws moisture from the cabinet through the suction pipe and converts it into water, which is then supplied to the water-cooling pipes through the diversion pipe. The radiative cooling coating on the surface of the diversion plate reflects sunlight, and the polyurethane foam on the inner wall of the chamber locks in the cold temperature, enabling the device to continuously supply water for cooling even on non-rainy days. This avoids the problems of temperature rise, increased resistance, and increased power consumption from the source, improving the overall energy-saving effect of the switchgear.

[0020] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0021] According to one embodiment of the present invention, Figure 1 as well as Figures 9-11 A high-reliability high-voltage switchgear includes a cabinet 1, a cooling component 3 for diverting rainwater is fixedly installed on the upper surface of the cabinet 1, and collection frames 2 are fixedly installed on both sides of the cooling component 3. The cooling component 3 includes a distribution plate 31 fixedly installed on the upper surface of the cabinet 1. A dehumidifier 32 is installed inside the distribution plate 31. Two distribution pipes 34 are fixedly installed at both ends of the dehumidifier 32. Two sets of distribution pipes 34 are provided, and a water-cooled pipe 35 is fixedly installed at one end of each set. Three sets of water-cooled pipes 35 are installed inside the cabinet 1. Two sets of dehumidifiers 32 are connected to the collection frame 2. A connecting pipe 36 is movably installed between the three sets of water-cooled pipes 35. A heat-absorbing pipe 37 is fixedly installed on the surface of each set of water-cooled pipes 35. The heat-absorbing pipe 37 is located inside the cabinet 1. To prevent rainwater from entering the cabinet 1 during rainy days, the cabinet 1 will close the openings originally used for heat dissipation. At this time, the heat inside the cabinet 1 will be effectively dissipated. The water is discharged through the water-cooling pipe 35, which allows the water inside the water-cooling pipe 35 to cool the outer shell of the cabinet 1. Since two sets of water-cooling pipes 35 are connected to the collection frame 2, the collection frame 2 will collect rainwater on rainy days and transport the rainwater to the inside of the water-cooling pipes 35 to cool the cabinet 1. The heat-absorbing pipe 37 located inside the cabinet 1 will directly absorb the heat inside the cabinet 1, thereby cooling the inside of the cabinet 1. The connecting pipe 36 allows each set of water-cooling pipes 35 to be filled with water. The rainwater poured in during rain allows the water inside the water-cooling pipes 35 to flow, further improving the heat absorption effect of the water-cooling pipes 35 and the heat-absorbing pipes 37, thus improving the heat dissipation effect of the cabinet 1.

[0022] The present invention will be further described below with reference to embodiments.

[0023] Please see Figures 1-11 All water-cooling pipes 35 are set at an angle and are in contact with the inner wall of the cabinet 1. The water-cooling pipes 35 are made of copper. The angled setting of the water-cooling pipes 35 allows the water inside the water-cooling pipes 35 to have the characteristics of flow, so that the high temperature boundary layer at the pipe wall is continuously eroded and destroyed, and low temperature cooling water is continuously introduced to participate in heat exchange, thereby greatly improving the heat absorption efficiency and heat dissipation effect. Furthermore, the fact that the water-cooling pipes 35 are made of copper can further improve the heat absorption efficiency, thereby reducing the heat inside the cabinet 1.

[0024] A suction pipe 33 is fixedly installed on the lower surface of the dehumidifier 32. One end of the suction pipe 33 is connected to the inside of the cabinet 1. The dehumidifier 32 is located inside the diversion plate 31. The suction pipe 33 can suck up the moisture inside the cabinet 1. Then the sucked moisture enters the dehumidifier 32 for conversion, turning the moisture into water and storing it inside the dehumidifier 32. When the water inside the dehumidifier 32 reaches the threshold, the dehumidifier 32 will transport the water to the water-cooling pipe 35 through the diversion pipe 34. When the environment is normal and the temperature inside the cabinet 1 gradually rises, the water inside the dehumidifier 32 will also be transported to the water-cooling pipe 35 through the diversion pipe 34 by the built-in water pump.

[0025] The diffuser plate 31 has a chamber 38 inside. The surface of the diffuser plate 31 is coated with a radiant cooling coating. The inner wall of the chamber 38 is lined with polyurethane foam. The dehumidifier 32 is located inside the chamber 38. The radiant cooling coating on the surface of the diffuser plate 31 allows the cabinet 1 to reflect sunlight in normal weather, which lowers the temperature inside the chamber 38. The polyurethane foam on the inner wall of the chamber 38 locks in the cold temperature inside the chamber 38. As a result of this double protection, the water in the water tank inside the dehumidifier 32 will be stored for a longer time, allowing the water inside the dehumidifier 32 to cool the cabinet 1 using the water-cooling pipe 35 even on non-rainy days.

[0026] A filter plate 21 is movably installed inside the collection frame 2. A guide rod 22 is fixedly installed at the bottom of the collection frame 2. A drain port 23 is opened on the lower surface of the collection frame 2. An isolation plate 24 is movably installed on the inner wall of the drain port 23. A drain pipe 25 is fixedly installed on the lower surface of the drain port 23 and is connected to a water cooling pipe 35. A plate groove 26 is opened on the inner wall of the collection frame 2. Two sets of plate grooves 26 are provided. An inner groove 27 is opened inside the collection frame 2. A trigger component 28 for opening and closing the isolation plate 24 is movably installed inside the inner groove 27. Impurities in the rainwater can be isolated by the filter plate 21, and the collection frame 2 can continuously collect rainwater on rainy days. Furthermore, by setting up the isolation plate 24 and the drain pipe 25, when the rainwater is collected to a certain extent, the isolation plate 24 can be flipped over, allowing the rainwater to enter the water cooling pipe 35 through the drain pipe 25. When the rainwater passes through the filter plate 21, the filter plate 21 will float up due to its plastic material. Since the filter plate 21 isolates impurities on its upper surface, the impurities will remain on the surface of the filter plate 21 due to the collection frame 2 before the filter plate 21 floats to its highest point. When the filter plate 21 floats to its highest point, the water source diverted by the diversion plate 31 and the falling rainwater will wash away the impurities on the surface of the filter plate 21 and discharge them into the collection frame 2.

[0027] Triggering component 28 includes a linkage component 281 movably disposed inside the inner groove 27 for adapting to rotation. A sliding plate 282 is movably disposed at one end of the linkage component 281, and a top plate 283 is movably disposed at the other end of the sliding plate 282. Both the top plate 283 and one end of the linkage component 281 are fixedly mounted with protrusions 285. A filter plate 21 is located between the two sets of protrusions 285. A baffle 286 is fixedly mounted on the outer surface of the protrusions 285. The protrusions 285 are slidably connected to the plate groove 26. When the filter plate 21 floats due to water inflow, as more water accumulates, when the filter plate 21 reaches the highest point of the collection frame 2, it contacts the protrusion 285 at one end of the baffle 286, thus lifting it and tilting the top plate 283. Due to the movable connection between the sliding plate 282 and the top plate 283, and the movable connection between the linkage component 281 and the sliding plate 282, one end of the top plate 283 lowers, and the sliding plate 285 tilts. When plate 282 descends, one end of linkage component 281 also descends. At this time, the isolation plate 24 connected to trigger component 28 will flip along with linkage component 281, thereby draining the water into the water cooling pipe 35 through drain pipe 25. At this time, slide plate 282 will be restricted by the inner groove 27, keeping top plate 283 and linkage component 281 in an inclined state. When the rain stops, filter plate 21 will also descend due to the drop in water level, but isolation plate 24 will remain in the same inclined state as linkage component 281, allowing the water inside collection frame 2 to drain completely. When the water inside collection frame 2 drains, filter plate 21 will contact the protrusion 285 at one end of linkage component 281, thereby pressing the protrusion 285 at one end of linkage component 281, causing linkage component 281 to return to a horizontal state, closing isolation plate 24, and resetting top plate 283.

[0028] Magnetic plates A271 and B272 are fixedly installed on the inner wall of the inner groove 27, and magnetic plate C284 is fixedly installed on the outer surface of the slide plate 282. Magnetic plate C284 is magnetically attracted to magnetic plates A271 and B272. When the top plate 283 is in a horizontal state, magnetic plates C284 and A271 are magnetically attracted, keeping the top plate 283 in a horizontal state. When the filter plate 21 rises and presses against the protrusion 285 at one end of the top plate 283, the slide plate 282 will be driven down by the top plate 283, causing magnetic plates C284 and B272 to be magnetically attracted, keeping the top plate 283 and the linkage component 281 in an inclined state. When the filter plate 21 descends, the isolation plate 24 can still remain in an open state.

[0029] The linkage component 281 includes a central rod 2811 disposed inside the inner groove 27. A central plate 2812 is fixedly disposed on the outer surface of the central rod 2811. Limiting grooves 2813 are opened at both ends of the central plate 2812. A telescopic rod 2814 is fixedly installed on the inner wall of the limiting groove 2813. A limiting plate 2815 is fixedly installed at one end of the telescopic rod 2814. A movable plate 2816 is fixedly installed at one end of the limiting plate 2815. With the setting of the telescopic rod 2814, the telescopic rod 2814 can move with the movable plate 2816 when the linkage component 281 or the top plate 283 is flipped, to compensate for the length lost due to the flipping, so that the slide plate 282 can be raised and lowered smoothly.

[0030] A long rod 241 is fixedly installed inside the isolation plate 24. A belt 287 is fitted on the outer surface of the long rod 241 and the center rod 2811. The isolation plate 24 is movably connected to the drain port 23 through the long rod 241. With the belt 287, the linkage component 281 can be rotated, which will also cause the isolation plate 24 to rotate, thereby opening the drain port 23 and allowing rainwater to enter the water cooling pipe 35.

[0031] A cabinet door 11 is hinged to one side of the cabinet body 1. A heat dissipation vent 12 is opened inside the cabinet door 11. An electric plate 13 is movably installed inside the heat dissipation vent 12. A rectangular groove 14 is opened inside the cabinet body 1. The rectangular groove 14 is adapted to the heat absorption pipe 37. A raindrop sensor 15 is installed on one side of the cabinet body 1. The raindrop sensor 15 is located above the cabinet door. The installation of the heat dissipation vent 12 can ensure the daily heat dissipation of the cabinet body 1. The installation of the electric plate 13 can ensure that rainwater will not enter the cabinet body 1 when it rains.

[0032] Working principle: When it rains in the external environment, the rain sensor 15 detects the rain and causes the electric plate 13 inside the heat dissipation vent 12 on the cabinet door 11 to close, preventing rainwater from entering the cabinet 1. Then, the cooling component 3 on the upper surface of the cabinet 1 starts to work, and the diversion plate 31 diverts the falling rainwater. The collection frames 2 on both sides of the cooling component 3 simultaneously start to collect the diverted rainwater. Then, the filter plate 21 inside the collection frame 2 isolates impurities in the rainwater. During this process, when the filter plate 21 has not floated to the highest point, the blocked impurities... The impurities will remain firmly on the surface of the filter plate 21, preventing them from entering the subsequent pipelines and causing blockages. As rainwater continuously flows in, the plastic filter plate 21 is lifted by the rainwater. Subsequently, when the filter plate 21 floats to the highest point of the collection frame 2, it will contact the protrusion 285 in the trigger component 28, causing the top plate 283 to tilt. Since the slide plate 282, the top plate 283, and the linkage component 281 are all movably connected, the lowering of one end of the top plate 283 will cause the slide plate 282 to fall, which in turn will cause one end of the linkage component 281 to fall as well. At the same time, the linkage component... 281, via the belt 287 on the outer surface of the long rod 241 on the central rod 2811 and the baffle plate 24, causes the baffle plate 24 to flip and open the drain port 23. Rainwater enters the water-cooling pipe 35 through the drain pipe 25. At this time, the rainwater diverted by the diverting plate 31 and the falling rainwater will jointly flush the surface of the filter plate 21 that floats to the highest point, washing away the previously retained impurities and draining them into the collection frame 2, preventing the accumulation of impurities from affecting rainwater collection and subsequent cooling effect. Then, the connecting pipe 36 between the three sets of water-cooling pipes 35 allows each set of water-cooling pipes 35 to be evenly cooled. The water-cooled pipes 35, filled with rainwater and fitted to the inner wall of the cabinet 1, keep the internal temperature of the cabinet 1 within a low range. This prevents the temperature from rising, which could intensify atomic movement and obstruct electron transport within the electrical components, thus preventing increased resistance. Simultaneously, the heat-absorbing pipes 37 on the surface of the water-cooled pipes 35 are embedded in the rectangular grooves 14 of the cabinet 1, directly absorbing heat from inside the cabinet 1 and further reducing the internal temperature. This ensures that the electrical components maintain a stable operating temperature, preventing resistance from increasing due to overheating, and allowing for smoother current transmission, thereby reducing unnecessary energy loss. When it rains outside, moisture will be present inside cabinet 1. At this time, the dehumidifier 32 in chamber 38 will draw out the moisture inside cabinet 1 through suction pipe 33 and convert it into water, which will be stored inside the dehumidifier 32. When it stops raining outside, the radiation cooling coating on the surface of the distribution plate 31 will reflect sunlight, and the polyurethane foam will maintain the low temperature inside chamber 38, allowing the rainwater inside the dehumidifier 32 to be stored for a longer time at a low temperature. On non-rainy days, the water inside the dehumidifier 32 will enter the water cooling pipe 35 to cooperate with the heat dissipation vent 12 to further improve the heat dissipation inside cabinet 1, continuously maintain the low temperature environment inside cabinet 1, and avoid the problem of increased power consumption due to increased temperature and resistance. While improving the heat dissipation effect of the switch cabinet, it can achieve stable and energy-saving operation.
