Description

Technical Field

[0001] This utility model belongs to the field of ring network box technology, specifically a primary and secondary fusion ring network box for preventing condensation. Background Technology

[0002] A primary and secondary integrated ring main unit is an electrical equipment consisting of a group of power transmission and distribution equipment (high-voltage switchgear) housed in a metal or non-metal insulated cabinet or assembled into a modular ring main unit. Its core components are load switches and fuses. It has advantages such as simple structure, small size, low price, improved power supply parameters and performance, and enhanced power supply safety. It is widely used in substations in load centers such as urban residential areas, high-rise buildings, large public buildings, and factories.

[0003] In existing technologies, some primary and secondary integrated ring main units are usually equipped with multiple sets of heat dissipation holes. The main function of these heat dissipation holes is to ensure that the unit can dissipate heat in a timely and effective manner during equipment operation, reduce the temperature difference between the inside and outside of the unit, and reduce the phenomenon of condensation inside the unit as the temperature difference decreases.

[0004] However, in practical applications, some primary and secondary integrated ring main units may be deployed in environments with high humidity. In such areas, the air contains a large amount of water vapor. Although the heat dissipation holes provided by the ring main unit can alleviate the condensation problem caused by the heat generated by the electrical equipment, they cannot eliminate the water vapor in the ambient air. Therefore, when the outside humid air enters the inside of the unit through the heat dissipation holes, it may still condense into dew on the inner wall of the unit and the surface of the electrical equipment, thereby damaging the internal electrical components. Therefore, a primary and secondary integrated ring main unit with anti-condensation is proposed to address the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figure 1 - Figure 5This utility model provides a primary and secondary fusion ring network box for preventing condensation, including a box body 1; an air outlet 2 is provided on the side wall of the box body 1; a cooling fan 3 is installed on the inner wall of the air outlet 2; an air inlet 6 is provided on the bottom side of the middle part of the box body 1; a support plate 43 is slidably connected to the inner wall of the air inlet 6; a rectangular shell 4 is in contact with the top of the support plate 43; a desiccant 41 is provided in the middle of the rectangular shell 4; a handle 42 is rotatably connected to the middle of the rectangular shell 4; a sliding groove 7 is provided on the inner wall of the air inlet 6; the end of the support plate 43 is slidably connected to the inner wall of the sliding groove 7; a prompting rod 44 is slidably connected through the bottom of the box body 1; during operation, the cooling fan 3 can blow out the heat inside the box body 1, while the cold air outside will enter the interior of the box body 1 through the air inlet 6, thus accelerating the airflow inside the box body 1 and reducing the self-heating of the hot air inside. However, there is a risk of condensation during cooling. When outside air enters the cabinet 1, it passes through the rectangular shell 4. At this time, the desiccant 41 installed inside the rectangular shell 4 absorbs the moisture in the air, ensuring the dryness of the air entering the cabinet 1 and further reducing the risk of condensation inside the cabinet 1. After the desiccant 41 absorbs moisture, its mass changes, causing the support plate 43 to move downward. The support plate 43, in turn, compresses the spring 45 and moves the indicator rod 44. The user can observe the length of the indicator rod 44 popping out from the outside of the cabinet 1 to judge the amount of desiccant 41 used. After the desiccant 41 is used up, the door of the cabinet 1 can be opened, and the rectangular shell 4 can be moved out from the air inlet 6 by pulling the handle 42. This allows for centralized replacement of the desiccant 41, improving convenience.

[0027] Furthermore, such as Figure 1 - Figure 3As shown, an air inlet pipe 5 is fixedly connected to the bottom of the housing 1; the inner wall of the air inlet pipe 5 is connected to the inner wall of the air inlet hole 6; a filter plate 52 slides through the side wall of the air inlet pipe 5; a pull block 510 is fixedly connected to the side wall of the filter plate 52; a baffle 51 is slidably connected to the side wall of the air inlet pipe 5; the baffle 51 contacts the side wall of the filter plate 52; a rectangular groove 57 is opened on the side wall of the air inlet pipe 5; a slider 56 is slidably connected to the inner wall of the rectangular groove 57; the side wall of the slider 56 is fixedly connected to the top side wall of the baffle 51; a second spring 55 is fixedly connected to the top of the slider 56; the top of the second spring 55 is fixedly connected to the inner wall of the rectangular groove 57. During operation, the air entering the housing 1 first passes through the air inlet pipe 5, at which time the filter plate 52 filters the dust and impurities in the air, improving the cleanliness of the inside of the housing 1. After a period of use, the filter plate 52 needs to be cleaned. During disassembly and maintenance, baffle 51 can be pushed, causing slider 56 to slide along the inner wall of rectangular groove 57. Simultaneously, slider 56 will compress spring 55 until baffle 51 no longer contacts filter plate 52. At this point, pull block 510 can be pulled, causing filter plate 52 to move out from the inner wall of air inlet duct 5. During installation, simply move baffle 51 to the upper side of the hole for installing filter plate 52, and then insert filter plate 52 into the inner wall of air inlet duct 5 until filter plate 52 is fully inserted. Then, release the limit of baffle 51. Spring 55 will push slider 56 to move in the opposite direction through its elasticity, and baffle 51 will also move in the opposite direction and contact filter plate 52, blocking filter plate 52 and ensuring the stability of filter plate 52 installation.

[0028] Furthermore, such as Figure 2 As shown, a spring 45 is sleeved on the outer wall of the indicator rod 44; one end of the spring 45 is fixed to the bottom of the support plate 43; the other end of the spring 45 is fixed to the inner wall of the slide groove 7. When working, the spring 45 has a certain elasticity, and it provides a certain support force to the rectangular shell 4 through its own elasticity. When the desiccant 41 is not used, the rectangular shell 4 will be on the top side of the middle of the air inlet 6. After the desiccant 41 absorbs a certain amount of moisture, its mass will change. At this time, the rectangular shell 4 and the support plate 43 will squeeze the slide groove 7, causing it to deform.

[0029] Furthermore, such as Figure 4 As shown, the bottom of the rectangular shell 4 is hollow. During operation, by designing the bottom of the rectangular shell 4 to be hollow, air can be smoothly passed through it and enter the interior of the box 1.

[0030] Furthermore, such as Figure 3 and Figure 5As shown, the side wall of the baffle 51 has a through groove 59; the inner wall of the through groove 59 is slidably connected to a push plate 53; the side wall of the air inlet pipe 5 has an L-shaped groove 54; the outer wall of the end of the through groove 59 is slidably connected to the inner wall of the L-shaped groove 54. During operation, when the baffle 51 is pushed so that it does not contact the filter plate 52, the push plate 53 can be pushed to slide on the inner wall of the through groove 59. At this time, the push plate 53 will be stuck at the top of the L-shaped groove 54, so the baffle 51 will not move downward. The user can then easily disassemble and assemble the filter plate 52, which improves practicality.

[0031] Furthermore, such as Figure 2 - Figure 3 As shown, multiple sets of spring 55, slider 56, and rectangular groove 57 are provided; and multiple sets of spring 55, slider 56, and rectangular groove 57 are symmetrically arranged with the center line of air inlet pipe 5 as the axis of symmetry. During operation, the multiple sets of spring 55, slider 56, and rectangular groove 57 can simultaneously squeeze both ends of baffle 51 to ensure the stability of baffle 51 in limiting the filter plate 52.

[0032] Furthermore, such as Figure 3 As shown, the inner wall of the air inlet pipe 5 is provided with a positioning groove 58, and the end of the filter plate 52 is inserted into the inner wall of the positioning groove 58. During operation, when the filter plate 52 is inserted into the inner wall of the air inlet pipe 5, its end will be inserted into the inner wall of the positioning groove 58, and the positioning groove 58 can support the end of the filter plate 52 to ensure the stability of the filter plate 52 installation.

[0033] Working principle: By activating the cooling fan 3, the heat inside the cabinet 1 is blown out, while cool air from the outside enters the cabinet 1 through the air inlet 6. This accelerates the airflow inside the cabinet 1, reducing the risk of condensation caused by the natural cooling of the hot air inside. Furthermore, when the outside air enters the cabinet 1, it passes through the rectangular shell 4. The desiccant 41 inside the rectangular shell 4 absorbs moisture from the air, ensuring the dryness of the air entering the cabinet 1 and further reducing the risk of condensation. After absorbing moisture, the desiccant 41 changes mass, causing the support plate 43 to move downwards. The support plate 43, in turn, compresses the spring 45, moving the indicator rod 44. The user can observe the length of the indicator rod 44 from the outside of the cabinet 1 to determine the amount of desiccant 41 used. After the desiccant 41 is used up, the cabinet door can be opened, and the rectangular shell 4 can be pulled out from inside the air inlet 6 by pulling the handle 42. This allows for centralized replacement of the desiccant 41, improving convenience.

[0034] Air entering the housing 1 first passes through the air inlet duct 5. At this point, the filter plate 52 filters dust and impurities from the air, improving the cleanliness of the housing 1. After a period of use, when the filter plate 52 needs to be disassembled and repaired, the baffle 51 can be moved by pushing the push plate 53. The baffle 51 will cause the slider 56 to slide along the inner wall of the rectangular groove 57. Simultaneously, the slider 56 will compress the second spring 55 until the baffle 51 no longer contacts the filter plate 52. Then, push the push plate 53 to slide along the inner wall of the through groove 59, causing the end of the push plate 53 to engage with the top of the L-shaped groove 54. At this point, it can be pulled... Pull block 510 will move filter plate 52, causing filter plate 52 to move out from the inner wall of air inlet pipe 5. During installation, simply move baffle 51 to the upper side of the hole for inserting filter plate 52, and then insert filter plate 52 into the inner wall of air inlet pipe 5 until filter plate 52 is fully inserted into the inner wall of air inlet pipe 5. At this time, the limit of push plate 53 on baffle 51 can be released. Spring 2 55 will push slider 56 to move in the opposite direction through its own elasticity. Baffle 51 will also move in the opposite direction and contact filter plate 52, blocking filter plate 52 and ensuring the stability of filter plate 52 installation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
