Abstract
Description
Technical Field
[0001] This utility model belongs to the field of low-voltage switchgear, and relates to a low-voltage switchgear with a protective structure. Background Technology
[0002] When low-voltage switchgear is installed outdoors, high temperatures and heavy electricity consumption can cause the internal temperature of the switchgear to rise. The higher the temperature, the greater the resistance of the electrical equipment, which can lead to a fire in the switchgear. A sudden fire in a low-voltage switchgear may ignite nearby buildings, vegetation, or injure pedestrians. Therefore, a protective structure needs to be designed to mitigate the hazards of a fire in a low-voltage switchgear. Summary of the Invention
[0003] To address the aforementioned problems, this utility model provides a low-voltage JP cabinet with a protective structure.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a low-voltage JP cabinet with a protective structure, comprising a low-voltage JP cabinet installed on a concrete base, wherein a protective structure is provided outside the low-voltage JP cabinet, the protective structure comprising a protective door provided on the front of the low-voltage JP cabinet and protective plates provided on the three vertical sides of the low-voltage JP cabinet, an air intake grille connected to the lower end of the protective plate, and two sunshades connected to the protective structure, the sunshades being provided above the low-voltage JP cabinet, the two sunshades being arranged side by side and spaced apart.
[0005] Preferably, a storage compartment is connected to the side of the protective plate away from the low-voltage JP cabinet, and a discharge port is provided on the lower part of the protective plate corresponding to the storage compartment, and a film is provided on the discharge port.
[0006] Preferably, a first support plate is connected to the top of the protective plate, and a second support plate is connected to the top of the protective door.
[0007] Preferably, a resin box is connected to the lower side of the sunshade.
[0008] Preferably, both the storage compartment and the resin box contain kaolin.
[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention provides both cooling and combustion suppression for low-pressure JP cabinets. A protective structure is installed outside the low-pressure JP cabinet, with a sunshade above it. This reduces direct sunlight exposure, lowering the cabinet's temperature. Rainwater collected by the sunshade falls onto the cabinet, further cooling it. An air intake grille connects to the lower end of the protective grille, allowing hot air to circulate upwards within the protective structure. The invention also includes a storage compartment and a resin box. During combustion, the stored kaolin is released, sealing the air intake grille and the upper part of the protective structure, thus suppressing combustion. Attached Figure Description

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0015] like Figure 1 , Figure 2 , Figure 3As shown, a low-voltage JP cabinet with a protective structure includes a low-voltage JP cabinet 1 installed on a concrete base. In order to reduce direct sunlight on the low-voltage JP cabinet 1, the present invention provides a protective structure 2 on the outside of the low-voltage JP cabinet 1. The protective structure 2 is fixed on the concrete base. The protective structure 2 includes a protective door 21 on the front of the low-voltage JP cabinet 1 and protective plates 22 on the three vertical sides of the low-voltage JP cabinet 1. The protective plates 22 and the protective door 21 are preferably made of high-temperature resistant and corrosion-resistant materials. The lower end of the protective plate 22 is connected to a horizontal air intake grille 23. The protective structure 2 is connected to two sunshades 24, which are set above the low-voltage JP cabinet 1. The two sunshades 24 are arranged side by side and spaced apart.
[0016] Specifically, the protective structure 2 and sunshade 24 of this utility model can reduce direct sunlight on the low-voltage JP cabinet 1, and the lower end of the protective plate 22 is provided with an air intake grille 23, which allows hot air inside the protective structure 2 to flow from bottom to top. The sunshade 24 can be set in the shape of a ridge, so that the rainwater collected falls between the two sunshades 24 and lands on the top of the low-voltage JP cabinet 1, thereby achieving the purpose of cooling the low-voltage JP cabinet 1.
[0017] In order to suppress the combustion of the low-pressure JP cabinet 1, the protective plate 22 of this utility model is connected to the storage compartment 25 on the side away from the low-pressure JP cabinet 1. The protective plate 22 is provided with a discharge port at the lower position of the storage compartment 25. The discharge port is sealed with a PET film 26 or resin. The melting point of the resin is usually around 120°C.
[0018] Furthermore, corresponding to the design of the outdoor low-voltage JP cabinet 1 with a rain cap 11, the top of the protective plate 22 of this utility model is connected to a first support plate 27, and the top of the protective door 21 is connected to a second support plate 28. Both the first support plate 27 and the second support plate 28 are lower than the rain cap 11, so that the area between the first support plate 27 and the rain cap 11 and the area between the second support plate 28 and the rain cap 11 form a vertical ventilation opening.
[0019] Furthermore, a resin box 29 is connected to the lower side of the sunshade 24.
[0020] Furthermore, both the storage compartment 25 and the resin box 29 contain kaolin or flame retardant.
[0021] Specifically, after the low-voltage JP cabinet 1 catches fire, the flames cause the temperature of the protective structure 2 to rise. The resin and film 26 with low melting point and low ignition point become unstable, thus releasing the stored kaolin. The kaolin released from the storage compartment 25 blocks the air intake grille 23, while the kaolin released from the resin box 29 falls on the first tray 27 and the second tray 28, blocking the gap between the first tray 27 and the rain cap 11, and blocking the gap between the second tray 28 and the rain cap 11, thereby reducing the ventilation inside the protective structure 2.
[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
