Description
Technical Field
[0001] The present invention relates to the technical field of ring main unit cabinets, and particularly to a primary-secondary integrated ring main unit cabinet. Background Art
[0002] The primary-secondary integrated complete set of ring main unit cabinets is an important part of modern power distribution systems. It integrates traditional primary equipment and intelligent secondary equipment, and achieves a perfect integration of the two through advanced technical means. Such ring main unit cabinets play a key role in improving the power supply reliability of the power grid, reducing power outage time, and optimizing the operation of the power grid.
[0003] In terms of structure, the primary-secondary integrated ring main unit cabinet takes the primary-secondary integrated ring main unit cabinet as the core, supplemented by key components such as high-voltage incoming line cabinets and low-voltage incoming line cabinets, to construct an efficient and stable power distribution system. Since the ring main unit cabinet is wrapped by the ring main unit cabinet from the outside, during heat dissipation, under the action of the cooling fans, the outside air first enters the ring main unit cabinet, then enters the ring main unit cabinet, and then is discharged from the inside of the ring main unit cabinet to the inside of the ring main unit cabinet, and then is discharged from the ring main unit cabinet to the outside, forming a heat dissipation cycle. This structural design itself has an impact on the heat dissipation efficiency;
[0004] In addition to the above factors, most existing cabinet-type power equipment uses cooling fans for heat dissipation. The purpose is to exchange the high-temperature gas inside the cabinet with the low-temperature gas outside, so as to cool the inside of the cabinet. However, nowadays, in most regions of our country, the temperature in summer exceeds 30 degrees, and the surface temperature even reaches 50 degrees or higher. The heat dissipation windows of the ring main unit cabinet are generally set at a position relatively close to the ground. Therefore, during the heat dissipation cycle, the situation where the air exchanged from the outside is hotter than the air inside the cabinet body may occur, resulting in too high a temperature inside the cabinet body and easily damaging the components inside the ring main unit cabinet. Summary of the Invention
[0005] The purpose of the present invention is to propose a primary-secondary integrated ring main unit cabinet to solve the problem that the traditional heat dissipation method cannot normally dissipate heat inside the ring main unit cabinet when the outside temperature is too high.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] A primary-secondary integrated ring main unit cabinet, including a cabinet body and a cabinet door hinged to the front end of the cabinet body, further including heat dissipation components arranged on both sides of the cabinet body. The heat dissipation components include heat dissipation windows arranged on both sides of the cabinet body. Both sides inside the cabinet body are movably connected with cooling fans, and a temperature reduction component for dissipating heat inside the cabinet body is arranged below the cooling fans inside the cabinet body;
[0008] The cooling component includes a telescopic component movably connected to the outside of the output shaft of the cooling fan. A gap is left at the rear end inside the box body for use as a heat dissipation channel, and a water tank is movably connected to the bottom of the gap. One side of the top of the water tank is movably connected to a pressing nozzle, and an atomizing spray hole is opened at the rear end of the top of the pressing nozzle.
[0009] As a further description of the above technical solution:
[0010] The telescopic component includes a sleeve movably sleeved on the outside of the output shaft of the cooling fan. A telescopic spring is fixedly connected between the inside of the sleeve and the output shaft of the cooling fan. An eccentric wheel is fixedly sleeved on the outside of the sleeve, and the inside of the sleeve is filled with petroleum wax.
[0011] As a further description of the above technical solution:
[0012] The eccentric wheel is composed of a fixed part and a movable part. The fixed part is fixedly sleeved on the outside of the sleeve. A spring hinge is movably connected between the fixed part and the movable part on the side close to the cooling fan, and the elastic force of the spring hinge is greater than the gravity of the movable part.
[0013] As a further description of the above technical solution:
[0014] The heat dissipation window is composed of a frame body and louvers. There are multiple louvers and they are distributed in a vertical linear array inside the frame body. A rotating shaft is movably connected between the louvers and the frame body.
[0015] As a further description of the above technical solution:
[0016] An adjusting component is provided between the heat dissipation window and the telescopic component. The adjusting component includes a rack rotatably connected to the side of the sleeve close to the heat dissipation window. A gear is fixedly connected to the rear part of the rotating shaft. A tooth chain is meshed between multiple gears. Tooth grooves meshed with the gears are opened inside the tooth chain, and teeth meshed with the rack are provided on the outside of the tooth chain. The rack slides through to the inside of the frame body and is limited by the frame body.
[0017] As a further description of the above technical solution:
[0018] A replenishing component is provided at the rear end of the box body. The replenishing component includes a water storage tank fixedly connected to the rear end of the box body. A filter screen is movably connected to the top of the water storage tank. A water guide pipe is fixedly communicated between the bottom of the water storage tank and the water tank, and a one-way valve is provided inside the water guide pipe.
[0019] As a further description of the above technical solution:
[0020] A drainage eaves is fixedly connected to the top of the box body, and a cabinet body is provided inside the box body.
[0021] As a further description of the above technical solution:
[0022] The water tank is in a C shape to wrap the cabinet body, and the distance that the drainage eaves extend out of the box body is less than the width of the reservoir.
[0023] As a further description of the above technical solution:
[0024] On both inner sides of the box body, shielding components are provided. The shielding components are composed of three baffles, and through holes are staggeredly arranged on the baffles.
[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:
[0026] Utilizing the high-temperature effect, when the petroleum wax inside the sleeve melts and changes from solid state to liquid state, its volume increases, thereby pushing the sleeve to slide along the surface of the output shaft of the cooling fan. And during the sliding process, the telescopic spring is pulled to stretch. After the sleeve moves, the eccentric wheel outside it will synchronously move above the pressing nozzle. At this time, the rotation of the cooling fan drives the rotation of its output shaft, and the rotation of the output shaft drives the synchronous rotation of the sleeve and the eccentric wheel. Since the bottom of the eccentric wheel is located below the pressing nozzle when the eccentric wheel is vertically downward, the pressing nozzle is intermittently pressed as the eccentric wheel rotates, so that the water inside the water tank is sprayed upward from the atomizing nozzle holes under the action of the pressing nozzle. The sprayed water is in an atomized state and can be instantly evaporated under the high-temperature effect. A large amount of heat is absorbed during the evaporation process of the water, thereby effectively dissipating heat and cooling the inside of the box body. At the same time, it can be reset after the temperature drops and will not perform the water spraying and cooling operation at low temperature, avoiding damage to the electrical components inside the box body caused by the inability of the atomized water sprayed at low temperature to evaporate.

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
[0049] As Figures 1-5 and Figure 10 with Figure 11 shown, a primary-secondary integrated ring main cabinet provided by the present invention includes a cabinet body 10 and a cabinet door 20 hinged to the front end of the cabinet body 10. A drainage eaves 80 is fixedly connected to the top of the cabinet body 10. A cabinet 90 is provided inside the cabinet body 10. The cabinet also includes heat dissipation components 30 arranged on both sides of the cabinet body 10. The heat dissipation components 30 include heat dissipation windows 31 arranged on both sides of the cabinet body 10. Heat dissipation fans 32 are movably connected to both sides inside the cabinet body 10. And a temperature reduction component 50 for dissipating heat inside the cabinet body 10 is provided below the heat dissipation fans 32 inside the cabinet body 10;
[0050] The temperature reduction component 50 includes a telescopic component 54 movably connected to the outside of the output shaft of the heat dissipation fan 32. A gap is left at the rear end inside the cabinet body 10 for use as a heat dissipation channel. And a water tank 51 is movably connected to the bottom of the gap. One side of the top of the water tank 51 is movably connected to a pressing nozzle 52. And an atomizing spray hole 53 is opened at the rear end of the top of the pressing nozzle 52;
[0051] The telescopic component 54 includes a sleeve 541 movably sleeved on the outside of the output shaft of the heat dissipation fan 32. A telescopic spring 543 is fixedly connected between the inside of the sleeve 541 and the output shaft of the heat dissipation fan 32. An eccentric wheel 542 is fixedly sleeved on the outside of the sleeve 541. The inside of the sleeve 541 is filled with petroleum wax;
[0052] The eccentric wheel 542 is composed of a fixed part 5421 and a movable part 5422. The fixed part 5421 is fixedly sleeved on the outside of the sleeve 541. A spring hinge 5423 is movably connected between the fixed part 5421 and the movable part 5422 on the side close to the heat dissipation fan 32. The elastic force of the spring hinge 5423 is greater than the gravity of the movable part 5422;
[0053] Blocking components 40 are provided on both sides inside the cabinet body 10. The blocking components 40 are composed of three baffles 41. And through holes 42 are staggeredly opened on the baffles 41.
[0054] Specifically, first, the functions of the primary side and the secondary side of the main transformer are integrated into one device to form a primary-secondary integrated ring main unit. Then, with the primary-secondary integrated ring main unit as the core, key components such as high-voltage incoming switchgear and low-voltage incoming switchgear are supplemented to form a cabinet body 90, constructing an efficient and stable power distribution system. And this power distribution system is placed in a box body 10 to form a primary-secondary integrated ring main box. A hinged door 20 is provided at the front end of the box body 10 for opening the box body 10 to operate and maintain the power distribution system. Heat dissipation components 30 are arranged on both sides of the box body 10 for dissipating heat from the inside of the box body 10. In order to utilize the principle of natural convection, improve the heat dissipation efficiency and reduce the condensate generated due to temperature difference, generally the heat dissipation components 30 of power distribution equipment are arranged at the bottom. Also, in high-temperature weather in summer, the surface temperature often reaches fifty degrees or even higher. Therefore, the traditional heat dissipation method cannot effectively dissipate heat and cool down the inside of the ring main box;
[0055] Based on this, at normal temperature, the cooling fan 32 works, sucking the outside air flow into the inside of the box body 10 through the heat dissipation window 31 on one side of the ring main box, dissipating heat with the high-temperature gas generated inside the box body 10 during operation, and then discharging it to the outside through the other side of the ring main box, thus completing the heat dissipation and cooling operation of the inside of the ring main box. When the outside temperature rises and cannot effectively cool down the inside of the ring main box, at this time, under the action of high temperature, the petroleum wax inside the sleeve 541 melts. When the petroleum wax changes from solid state to liquid state, its volume increases, thus pushing the sleeve 541 to slide along the surface of the output shaft of the cooling fan 32, and stretching the telescopic spring 543 during the sliding process. After the sleeve 541 moves, the eccentric wheel 542 outside it will synchronously move above the pressing nozzle 52. At this time, the rotation of the cooling fan 32 drives the rotation of its output shaft, and the rotation of the output shaft drives the synchronous rotation of the sleeve 541 and the eccentric wheel 542. Since the bottom of the eccentric wheel 542 is below the pressing nozzle 52 when the eccentric wheel 542 is vertically downward, the pressing nozzle 52 is intermittently pressed as the eccentric wheel 542 rotates, so that the water inside the water tank 51 is sprayed upward from the atomizing spray holes 53 under the action of the pressing nozzle 52. The sprayed water is in a misty state and can be instantly evaporated under the action of high temperature. A large amount of heat will be absorbed during the evaporation process of the water, thus effectively dissipating heat and cooling down the inside of the box body 10. It should be noted that the pressing nozzle 52 belongs to the prior art, and its structure and principle are common knowledge in this field, so it will not be elaborated in detail here. In addition, a telescopic rod is provided between the sleeve 541 and the output shaft of the cooling fan 32. One of the purposes is to limit the telescopic spring 543 and at the same time realize the fixation of the torsional direction between the sleeve 541 and the output shaft of the cooling fan 32 to ensure that the sleeve 541 can rotate synchronously with the output shaft of the cooling fan 32;
[0056] In addition, the eccentric wheel 542 is designed to consist of a fixed part 5421 and a movable part 5422, which are connected by a spring hinge 5423. During the movement of the sleeve 541, when the eccentric wheel 542 contacts the pressing nozzle 52 in the vertically downward process, under the reaction force exerted by the pressing nozzle 52 on the eccentric wheel 542, the movable part 5422 of the eccentric wheel 542 will rotate away from the pressing nozzle 52 with the spring hinge 5423 as the pivot point until the eccentric wheel 542 follows the sleeve 541 to move to directly above the pressing nozzle 52. Then, under the elastic recovery effect of the spring hinge 5423, the movable part 5422 of the eccentric wheel 542 rotates back to the initial state;
[0057] After that, the atomized water sprays out and follows the outside air to pass through the gap at the rear of the box body 10 and is discharged from the heat dissipation window 31 on the other side of the box body 10. It should be noted that the electrical components inside the box body 10 are all arranged inside the cabinet body 90, and the side surface of the cabinet body 90 is in a closed state. Therefore, the atomized water sprayed out will not damage the electrical components inside the cabinet body 90 from the side of the cabinet body 90. However, considering that a heat dissipation area is provided at the rear end of the cabinet body 90, in order to prevent the atomized water from not evaporating in time and entering the inside of the cabinet body 90 from the rear of the cabinet body 90 and adhering to the electrical components to cause circuit failures, shielding components 40 are specifically arranged on both sides inside the box body 10, so that the atomized water flows in a serpentine path when passing through the through holes 42 distributed in a staggered manner on the three-layer baffle 41. Furthermore, the baffle 41 effectively intercepts the water that has not been completely evaporated, preventing the damage caused by the water vapor to the electrical components;
[0058] Finally, it should be clarified that since the heat dissipation fans 32 inside the power distribution equipment operate continuously throughout the year, and the melting point of the petroleum wax is between 30 - 35 degrees Celsius, the temperature during the day in summer is sufficient to melt it. Also, due to the temperature difference between day and night in summer, when the outside temperature drops below 30 degrees Celsius after the end of summer and in the late night of summer, when the original heat dissipation fans 32 can effectively cool the inside of the box body 10, at this time, the petroleum wax inside the sleeve 541 solidifies under the low temperature. During the solidification process, the telescopic spring 543 resets and pulls the sleeve 541 back, so that the sleeve 541 drives the eccentric wheel 542 to reset, causing the eccentric wheel 542 to be misaligned and separated from the pressing nozzle 52 and no longer press the pressing nozzle 52. Therefore, spraying and cooling operations will not be carried out at low temperatures, avoiding damage to the electrical components inside the box body 10 caused by the atomized water that cannot evaporate at low temperatures.
[0059] As Figure 3 、 Figure 6 shown in Figure 7 the heat dissipation window 31 consists of a frame body 311 and louvers 312. There are multiple louvers 312, which are distributed in a vertical linear array inside the frame body 311, and a rotating shaft 313 is movably connected between the louvers 312 and the frame body 311;
[0060] An adjusting component 60 is provided between the heat dissipation window 31 and the telescopic component 54. The adjusting component 60 includes a rack 61 rotatably connected to one side of the sleeve 541 close to the heat dissipation window 31. A gear 62 is fixedly connected to the rear part of the rotating shaft 313. A tooth chain 63 is meshed and connected between multiple gears 62. Tooth grooves 631 meshing with the gears 62 are formed inside the tooth chain 63. Teeth 632 meshing with the rack 61 are provided on the outer side of the tooth chain 63. The rack 61 slidably penetrates into the interior of the frame body 311 and is limited by the frame body 311, so that the rack 61 can only move horizontally and will not rotate following the sleeve 541.
[0061] Specifically, when the sleeve 541 in the telescopic component 54 displaces towards the side close to the heat dissipation window 31, it will push the rack 61 to move synchronously. At this time, since the rack 61 meshes with the teeth 632 on the outer side of the tooth chain 63, the tooth chain 63 will be driven to rotate. Also, because the tooth grooves 631 inside the tooth chain 63 mesh with the gears 62 outside the rotating shaft 313, when the tooth chain 63 rotates, it drives the gears 62 to rotate synchronously. Furthermore, the gears 62 drive the louvers 312 to rotate synchronously through the rotating shaft 313, so that the originally vertically inclined louvers 312 rotate to a horizontally inclined state, thereby enlarging the gap between adjacent louvers 312, enabling the outside air to enter and exit the interior of the box body 10 more quickly, thus accelerating the heat dissipation efficiency and further improving the heat dissipation effect inside the box body 10. And in a low-temperature environment, as the sleeve 541 resets and drives the rack 61 to move back, the tooth chain 63 and the gears 62 both rotate back. Furthermore, the originally horizontally inclined louvers 312 rotate to a vertically inclined state, reducing the gap between adjacent louvers 312 and slowing down the speed of the outside air entering and exiting the interior of the box body 10, avoiding the situation that the heat dissipation efficiency is too fast in winter, resulting in too low a temperature inside the box body 10 and causing electrical components to fail or even be damaged. The ring main unit can adjust the cooling method according to different weather conditions, ensuring both the cooling efficiency and the safety of the electrical components inside the box body 10. And at the late night in summer, when the temperature drops, the louvers 312 can also be driven, making the ventilation opening of the heat dissipation window 31 smaller. On the one hand, it can reduce the probability of dew generated by the day-night temperature difference in summer from entering the interior of the ring main unit. On the other hand, it does not require frequent manual operation, improving its practicability.
[0062] Such as Figure 8 And Figure 9As shown in the figure, a replenishment component 70 is provided at the rear end of the box body 10. The replenishment component 70 includes a water storage tank 71 fixedly connected to the rear end of the box body 10. A filter screen 72 is movably connected to the top of the water storage tank 71. A water guide pipe 73 is fixedly connected and communicated between the bottom of the water storage tank 71 and the water tank 51. And a one-way valve is provided inside the water guide pipe 73, which on the one hand ensures the stability of the air pressure inside the water tank 51, and on the other hand prevents the water inside the water tank 51 from flowing back into the water storage tank 71; the water tank 51 is in a C shape to wrap the cabinet body 90, and the distance that the drainage eaves 80 extends out of the box body 10 is less than the width of the water storage tank 71, so that the rainwater falling on the drainage eaves 80 can be collected into the water storage tank 71, which speeds up the collection speed of the rainwater and improves the replenishment efficiency.
[0063] Specifically, a water tank 51 is arranged inside the box body 10. The fundamental purpose is to spray atomized water into the air to improve the cooling effect when cooling. On this basis, the volume of the water tank 51 is increased so that it spans the entire inner width of the box body 10. The increase in the water tank 51 ensures that there is enough water body for auxiliary heat dissipation and also reduces the frequency of water replenishment. At the same time, the large water body water tank 51 is arranged in a C shape to wrap the cabinet body 90, playing a heat preservation role. Utilizing the physical property of the high specific heat capacity of water, the highest and lowest temperature values inside the box body 10 in summer and winter are reduced. Cooperating with the operation of the heat dissipation fan 32, the heat dissipation effect inside the box body 10 is further improved.
[0064] In addition, in line with the characteristics of large summer rainfall, the water storage tank 71 can collect rainwater and flow into the water tank 51 through the water guide pipe 73 to replenish the water tank 51, while the filter screen 72 can intercept impurities in the rainwater to avoid clogging the atomizing spray holes 53 when the impurities enter the water tank 51 and are discharged from the atomizing spray holes 53. Through rainfall replenishment, the sufficiency of the water source inside the water tank 51 is ensured, ensuring that the cooling component 50 can work stably for a long time. While ensuring the cooling effect, the sustainability of cooling is also ensured.
[0065] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
