Description

Technical Field

[0001] This invention relates to the field of transformer heat dissipation technology, specifically a water spray auxiliary heat dissipation system for main transformer heat sinks. Background Technology

[0002] Substation main transformers often use oil-immersed self-cooled transformers. During peak summer seasons, due to high temperatures and the surge in residential cooling loads, full load conditions frequently occur. During full load periods, the upper oil temperature of the main transformer exceeds 85°C. Overheating of the main transformer leads to oil aging, reduced winding insulation, and affects the transformer's lifespan. To ensure safe power supply during peak summer seasons, emergency cooling measures are required, such as blowing air in front of the radiator to cool it. However, this method is slow, resulting in prolonged overheating of the main transformer and ineffective heat dissipation, failing to achieve intelligent, automatic, and rapid cooling.

[0029] 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.

[0030] Please see Figure 1-6 This invention provides a technical solution: a water spray auxiliary heat dissipation system for main transformer heat sinks, comprising a spray cooling system. The spray equipment includes a housing 1, a fixing component 3 on the side of the housing 1, and a rainwater collection component 4 on the top of the housing 1. The rainwater collection component 4 includes a collection funnel 41 for collecting rainwater and a rotating cover 42 to prevent evaporation. A spray component 5 is provided on one side of the rainwater collection component 4. The spray component 5 includes a primary water pump 51, which is bolted to the top of the collection funnel 41. A spray pipe 52 is fixedly connected to the output end of the primary water pump 51. Multiple atomizing nozzles 53 are fixedly connected to the side. A cooling mechanism 6 is set inside the housing 1. The cooling mechanism 6 includes a cooling box 61, which is fixedly connected inside the housing 1. A semiconductor cooling chip 62 is installed on the outside of the cooling box 61 by bolts. Multiple metal cooling plates 63 are set inside the cooling box 61. The metal cooling plates 63 are connected to the cooling end of the semiconductor cooling chip 62. A circulating water purification component 7 is set below the cooling mechanism 6. The circulating water purification component 7 includes an oil scraper 77 and a water storage tank 73. An oil suction nozzle 76 is installed at the bottom of the oil scraper 77 for drawing oil away and collecting it.

[0031] It should be noted that the second water pump 610 draws water from the collection tank 45 into the cooling tank 61, and from the top of the cooling tank 61 into the top metal cooling plate 63. The semiconductor cooling chip 62 cools the metal cooling plate 63. The water moves down to the next layer through the fixed partition 65 and the movable partition 66. During this process, the water is cooled. Then the first water pump 51 sprays the cooled water onto the transformer heat sink through the spray pipe 52 and the atomizing nozzle 53 to cool it down. When the temperature reaches the rated threshold, the cooling is stopped.

[0032] like Figure 3 , 45. Three metal cooling plates 63 are provided. Each metal cooling plate 63 has two fixed meshes 65 bolted to its top. The two fixed meshes 65 are slidably connected to movable meshes 66 on their adjacent sides. A crossbar 67 is welded between two adjacent movable meshes 66. A connecting rod 68 is welded between the upper and lower crossbars 67. The connecting rod 68 is slidably connected to the metal cooling plate 63. A second water pump 610 is bolted to the top of the inner wall of the cooling box 61. An electric telescopic rod 64 is bolted to the bottom of the cooling box 61. The output end of the electric telescopic rod 64 extends into the interior of the cooling box 61 and is fixed to the bottom crossbar 67. Each end of the metal cooling plate 63 has a drain hole 69. The drain holes 69 of the upper and lower atomizing nozzles 53 are staggered. The input end of the first water pump 51 is connected to the bottom of the cooling box 61.

[0033] It should be noted that both the fixed partition 65 and the movable partition 66 of the present invention are provided with through holes. When the two are at the same height, the through holes are connected, and water can quickly pass through the fixed partition 65 and the movable partition 66. When the water temperature is high and the cooling time of the water needs to be increased, the electric telescopic rod 64 drives the connecting rod 68 to rise and fall through the connecting rod 68, and the crossbar 67 drives the movable partition 66 to rise. At this time, the through holes between the fixed partition 65 and the movable partition 66 are misaligned and mutually blocked. At this time, the fixed partition 65 and the movable partition 66 form a water-blocking plate structure, thereby blocking the flow rate of water and allowing the water to stay in the cooling tank 61 for a longer period of time. The semiconductor cooling chip 62 transfers the low temperature to the water through the metal cold conduction plate 63, so that it is cooled quickly.

[0034] like Figure 1 The fixing component 3 includes a limiting slide rail 31, which is welded to the outside of the housing 1. Two clamping plates 32 are symmetrically slidably connected to the outside of the limiting slide rail 31. A bidirectional lead screw 33 is rotatably connected to the outside of the housing 1, and the bidirectional lead screw 33 is threadedly connected to the two clamping plates 32.

[0035] It should be noted that the housing 1 can be installed near the transformer. By rotating the bidirectional lead screw 33, the clamping plate 32 moves towards the center under the action of the symmetrical thread of the bidirectional lead screw 33. The housing 1 is fixedly installed on the designated mounting beam by the clamping of the two clamping plates 32.

[0036] like Figure 1 , 23, 4, The collecting funnel 41 is welded to the top of the collecting funnel 41. The rotating cover plate 42 is rotatably connected to both ends of the top of the collecting funnel 41. A support spring 43 is installed between the rotating cover plate 42 and the inner wall of the collecting funnel 41. Electromagnets 44 are bolted to the bottom of the rotating cover plate 42 and the side of the collecting funnel 41. When the two corresponding electromagnets 44 are energized, their magnetic poles are opposite. A collection box 45 is provided inside the housing 1 and below the collecting funnel 41. The input end of the second water pump 610 is connected to the collection box 45 through a water pipe.

[0037] It should be noted that when rain is detected, the electromagnets 44 are energized simultaneously. The magnetic poles of the corresponding electromagnets 44 are opposite when energized, and the attraction they generate is greater than the elastic force of the supporting spring 43. Under the action of this attraction, the rotating cover 42 is pulled into the collection funnel 41, causing its movable end to tilt downward. At this time, rainwater enters the collection box 45 through the collection funnel 41 for collection. When the rain ends, the electromagnets 44 are de-energized. Under the action of the elastic force of the supporting spring 43, the rotating cover 42 is pushed off. In this way, the two rotating covers 42 cover the collection funnel 41, preventing the entry of garbage and reducing the evaporation of water.

[0038] like Figure 3 , 4 6. The circulating water purification component 7 also includes a settling tank 72, which is bolted to the inner wall of the housing 1. A recovery tank 71 is welded to the outer side of the housing 1. The recovery tank 71 is connected to the settling tank 72 via a water pipe. A water storage tank 73 is fixedly connected to the bottom of the settling tank 72. A third water pump 74 is bolted to the inside of the housing 1. The output end of the third water pump 74 is connected to the collection tank 45 via a water pipe. The input of the third water pump 74 is connected to the water storage tank 73 via a water pipe. An oil scraper 77 is fixedly connected to the inner wall of the recovery tank 71. A fourth water pump 75 is fixedly connected to one side of the top of the oil scraper 77. The input end of the fourth water pump 75 is connected to the oil suction nozzle 76 via a pipe. The output end of the fourth water pump 75 is fixedly connected to an oil collection tank 78. The oil collection tank 78 is fixed to the inner wall of the housing 1.

[0039] It should be noted that the water sprayed by this invention flows down the transformer heat sink to the recycling tank 71 below. During this process, the water contains dust and oil stains. The water enters the settling tank 72 through the recycling tank 71 for settling. When the water level is higher than the edge of the settling tank 72, it flows through the settling tank 72 to the water storage tank 73. During this process, the oil stains float on the water surface due to density. The oil scraper 77 blocks the oil stains. The No. 4 water pump 75 generates an upward suction force through the oil suction nozzle 76. Under the action of suction force, the oil stains are drawn into the oil collection tank 78. The clean water flows to the water storage tank 73 and is sent to the collection tank 45 by the No. 3 water pump 74 for cooling and use.
