Description

Technical Field

[0001] The utility model relates to the technical field of transformer substation outdoor boxes, in particular to a transformer substation outdoor box with moisture-proof and dehumidification functions. Background Art

[0002] In the power system, the substation outdoor box is one of the key equipment. The stability and dryness of its internal environment are crucial to ensure the safe and stable operation of the power system. Therefore, a substation outdoor box with moisture-proof function has appeared on the market.

[0003] For example, Chinese Patent Publication No. CN203859415U discloses a moisture-proof and dehumidifying outdoor cabinet for substations. This existing device configures the cabinet body into a closed structure to prevent moisture from entering the cabinet. A condensing dehumidifier is also installed within the cabinet body. This design, combined with civil engineering and other aspects, results in a comprehensive design suitable for substation use. This addresses the current problem of condensation forming on such equipment, preventing components such as cables and relays from becoming damp and causing equipment failures. However, while this existing device can reduce humidity inside the cabinet to a certain extent, it still has numerous limitations due to a lack of systematic design considerations. For example, condensation can easily accumulate in the condensing dehumidifier over long periods of operation, which, if not properly managed, can exacerbate the moisture problem inside the cabinet. Furthermore, existing outdoor cabinets neglect dedicated protection for key components such as cables and relays in their structural design, and fail to actively dehumidify the components within the cabinet. This makes these components extremely susceptible to moisture in humid environments, causing equipment failures and impacting the normal operation of the power system. Utility Model Content

[0004] The purpose of the utility model is to provide a substation outdoor box with moisture-proof and dehumidification functions. By operating the electric telescopic rod to control the movement of the baffle, external air is prevented from directly entering the substation outdoor box body, thereby avoiding the accelerated accumulation of moisture brought in by the external air flow in the substation outdoor box body, and effectively protecting the internal substation components from damage.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a substation outdoor box with moisture-proof and dehumidification functions, comprising a base, a substation outdoor box body is provided on the top of the base, a threading hole for power transmission is provided on the outside of the substation outdoor box body, and a moisture-proof and dehumidification component is provided in the substation outdoor box body for moisture-proof and dehumidification of the substation equipment in the substation outdoor box body.

[0006] The moisture-proof and dehumidification component includes an electric fan for extracting air and an air filter plate for filtering the air. The moisture-proof and dehumidification component also includes an electric heating roller for heating the air.

[0007] Preferably, the substation outdoor box body is also provided with a regulating filter assembly for filtering dust and impurities in the air. The regulating filter assembly includes a first mounting frame arranged outside the substation outdoor box body, and a filter screen for filtering the air is slidably provided in the first mounting frame.

[0008] Preferably, a connecting strip is fixed to the outside of the filter screen, a sliding groove for the connecting strip to slide is provided in the first installation frame, and a handle is also fixed to the top of the filter screen.

[0009] Preferably, the substation outdoor box body is also provided with an adjustment opening and closing component for adjusting the ventilation of the substation outdoor box body, and the adjustment opening and closing component includes a second mounting frame arranged in the substation outdoor box body, and a third mounting frame is fixed to the top of the second mounting frame, and an electric telescopic rod is fixed to the top of the third mounting frame, and a baffle is fixed to the output end of the electric telescopic rod, and the baffle is slidably connected to the second mounting frame and the third mounting frame.

[0010] Preferably, an inspection cover is provided on the top of the third installation frame for facilitating the inspection of the electric telescopic rod.

[0011] Preferably, the moisture-proof and dehumidification component further includes a first connecting frame fixed in the second installation frame, and the electric fan is arranged in the first connecting frame.

[0012] Preferably, the moisture-proof and dehumidification assembly further comprises a second connecting frame fixed outside the second installation frame, and the second connecting frame is provided with an air filter plate for filtering and absorbing moisture in the extracted air.

[0013] Preferably, the moisture-proof and dehumidification component further includes a third connecting frame arranged outside the second connecting frame, and the electric heating roller is arranged in the third connecting frame.

[0014] Compared with the existing technology, the utility model provides a substation outdoor box with moisture-proof and dehumidification functions, which has the following beneficial effects:

[0015] 1. This moisture-proof and dehumidifying substation outdoor box uses a motorized telescopic rod to control the movement of the baffle, which flexibly closes the second mounting frame, preventing outside air from directly entering the box. This prevents moisture introduced by external airflow from accumulating inside the box, effectively protecting internal substation components from damage. This design not only improves the sealing of the box but also ensures that the substation equipment operates in a relatively stable environment, extending the equipment's service life.

[0016] 2. This moisture-proof and dehumidifying substation outdoor box adjusts the baffle position when moisture accumulates inside the box, activating the electric blower and air filtration system. This double-filtered, outside air is drawn into the box, where it is further heated to remove moisture. This significantly improves the airflow conditions inside the box, achieving highly effective moisture-proof and dehumidification. Furthermore, the device features a convenient filter cleaning mechanism that allows for easy removal and cleaning of the filter by pulling a handle. This effectively prevents poor air circulation caused by dust accumulation and ensures the continued efficient operation of the filtration system. The combination of these two functions not only enhances the moisture-proof and dehumidification capabilities of the box, but also simplifies filter maintenance, improving the reliability and usability of the entire device.

DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Example 1: Please refer to Figures 1-6 The utility model provides a technical solution: a substation outdoor box with moisture-proof and dehumidification functions, including a base 1, a substation outdoor box body 2 is provided on the top of the base 1, a substation outdoor box body 2 is provided with a threading hole 3 for power transmission, and a moisture-proof and dehumidification component 6 is provided in the substation outdoor box body 2 for moisture-proof and dehumidification of the substation equipment in the substation outdoor box body 2.

[0026] The dehumidification assembly 6 includes a motorized fan 62 for extracting air, an air filter 64 for filtering the air, and an electric heating roller 66 for heating the air. The integrated dehumidification assembly 6, particularly the effective extraction by the motorized fan 62, the filtration by the air filter 64, and the heating by the electric heating roller 66, ensures that the substation equipment operates in a dry environment, reducing moisture-related failures and maintenance costs.

[0027] Furthermore, the substation outdoor box body 2 is also equipped with a regulating filter assembly 4 for filtering dust and impurities in the air. The regulating filter assembly 4 includes a first mounting frame 41 disposed outside the substation outdoor box body 2, within which a filter screen 42 for filtering the air is slidably mounted. The additional regulating filter assembly 4, particularly the sliding filter screen 42 within the first mounting frame 41, effectively blocks external dust and impurities from entering the substation outdoor box body 2, protecting internal equipment from contamination. The sliding design of the filter screen 42 also facilitates replacement and cleaning, maintaining efficient filtering performance.

[0028] Furthermore, a connecting strip 43 is fixed to the outside of the filter 42, a sliding groove is provided in the first mounting frame 41 for the connecting strip 43 to slide, and a handle 44 is fixed to the top of the filter 42. The design of the connecting strip 43 and the sliding groove ensures that the filter 42 is securely installed and easy to slide out. The addition of the handle 44 greatly facilitates the operator's cleaning of the filter 42, improving maintenance efficiency and safety.

[0029] Furthermore, the substation outdoor box body 2 is also provided with an adjustable opening and closing assembly 5 for adjusting the ventilation of the substation outdoor box body 2. The adjustable opening and closing assembly 5 includes a second mounting frame 51 disposed in the substation outdoor box body 2. A third mounting frame 52 is fixed to the top of the second mounting frame 51. An electric telescopic rod 54 is fixed to the top of the third mounting frame 52. A baffle 55 is fixed to the output end of the electric telescopic rod 54. The baffle 55 is slidably connected to the second mounting frame 51 and the third mounting frame 52. The baffle 55, controlled by the electric telescopic rod 54, flexibly adjusts the ventilation state of the substation outdoor box body 2. The substation outdoor box body 2 can be closed to prevent moist air from entering when needed, and can be opened for air exchange when necessary, thus realizing intelligent management.

[0030] Furthermore, a maintenance cover 53 is provided on the top of the third mounting frame 52 for facilitating the maintenance of the electric telescopic rod 54. The addition of the maintenance cover 53 facilitates the operator to perform maintenance and repair of the electric telescopic rod 54 when necessary, thereby improving the reliability and service life of the equipment.

[0031] Example 2: Please refer to Figure 6 In combination with the first embodiment, it is further obtained that the moisture-proof dehumidification assembly 6 further includes a first connecting frame 61 fixed in the second mounting frame 51, and the electric fan 62 is disposed in the first connecting frame 61. The design of the first connecting frame 61 provides a stable mounting platform for the electric fan 62, ensuring the efficiency of air extraction and circulation.

[0032] Furthermore, the moisture-proof and dehumidification assembly 6 includes a second connecting frame 63 fixed to the outside of the second mounting frame 51. The second connecting frame 63 houses an air filter plate 64 for filtering and absorbing moisture from the extracted air. The second connecting frame 63 and the air filter plate 64 within it effectively remove moisture from the air, further enhancing the moisture-proof and dehumidification effect and protecting the substation equipment from moisture.

[0033] Furthermore, the moisture-proof and dehumidification assembly 6 includes a third connecting frame 65 disposed outside the second connecting frame 63, and an electric heating roller 66 is disposed within the third connecting frame 65. The third connecting frame 65 and the electric heating roller 66 within it further remove residual moisture by heating the air, thereby improving the overall efficiency of the moisture-proof and dehumidification assembly 6 and ensuring stable operation of the substation equipment in extremely humid environments.

[0034] In actual operation, in daily use, in order to prevent external air from entering the substation outdoor box body 2, accelerating the accumulation of water vapor and damaging the internal substation components, the following measures can be taken: open the electric telescopic rod 54, so that the baffle 55 falls, and close the second mounting frame 51, thereby preventing external air from entering the substation outdoor box body 2.

[0035] Over time, moisture may accumulate inside the substation outdoor box 2. In this case, the electric telescopic rod 54 is operated again, allowing the baffle 55 to slide to the third mounting frame 52, thus connecting the inside and outside of the substation outdoor box 2. Next, the electric blower 62 is activated to draw in outside air. This air is first filtered through the filter 42 to remove impurities, and then passes through the air filter plate 64 to further remove moisture, thereby changing the airflow conditions inside the substation outdoor box 2 and achieving a moisture-proof and dehumidifying effect.

[0036] In order to enhance the moisture-proof and dehumidifying effect, the electric heating roller 66 in the third connecting frame 65 can be opened to heat the air after the secondary filtration.

[0037] In addition, to maintain the filtration efficiency of the filter 42 and prevent dust accumulation from causing poor air circulation, the filter needs to be cleaned regularly. The specific operation is: pull the handle 44, remove the filter 42 with the help of the connecting strip 43 for cleaning, and push it back into the chute after cleaning.

[0038] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
