Description

Technical Field

[0001] This utility model relates to the field of cabinet dehumidification technology, specifically to a low-pressure cabinet with a dehumidification device. Background Technology

[0002] High and low voltage switchgear is a type of electrical equipment. External lines first enter the main control switch inside the cabinet, and then enter the branch control switches. Each branch circuit is configured according to its needs. Examples include instruments, automatic control systems, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage switchgear rooms and high-voltage busbars, such as those in power plants.

[0003] For example, CN220066492U discloses a dehumidification device for high and low voltage cabinets, including a cabinet body. A U-shaped protective plate is fixedly installed on the inner wall of the cabinet body. An suction fan is fixedly installed inside the U-shaped protective plate. A main housing is fixedly installed on the inner wall of the U-shaped protective plate. A partition plate is fixedly installed on the inner wall of the main housing. This invention utilizes the U-shaped protective plate fixedly installed on the inner wall of the cabinet body, and the suction fan and main housing respectively arranged inside the U-shaped protective plate. This allows the suction fan to transport moisture to airflow holes opened at the top of the partition plate, which then diffuses into the interior of the main housing. Calcium chloride particles placed on the upper surface of the filter plate react with the moisture, and the resulting water flows into the interior of the connecting pipe, thus being discharged from the interior of the cabinet. This structure can convert and discharge the moisture generated inside the cabinet, thereby indirectly protecting the components inside the cabinet.

[0004] However, in implementing the relevant technology, the above-mentioned high and low pressure cabinet dehumidification device has the following problems: it is difficult to absorb moisture in the air and it is difficult to heat the air to keep it dry, resulting in the inability to dry and absorb moisture in the air, leaving moisture and air in the air, thus reducing the dehumidification efficiency of the cabinet body. Therefore, a low pressure cabinet with a dehumidification device is proposed. Utility Model Content

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0030] Example 1

[0031] Please see Figure 1 - Figure 5 A low-voltage cabinet with a dehumidification device includes: a low-voltage cabinet body 1;

[0032] Dehumidification unit 2 is installed on the top of the low-voltage cabinet body 1 and is used to dehumidify the moisture inside the low-voltage cabinet body 1.

[0033] The dehumidification mechanism 2 includes a ventilation hood 21 that is fixedly installed through the top of the low-voltage cabinet body 1, a fan 22 that is fixedly installed inside the ventilation hood 21, and a rectangular frame 23 that is fixedly installed on the top of the low-voltage cabinet body 1 and fitted onto the outside of the ventilation hood 21. A drawer frame 25 is provided inside the rectangular frame 23. From top to bottom, a mesh screen 26, a moisture-absorbing cotton 27, a filter screen 29, and a heating wire 210 are fixedly installed inside the drawer frame 25. A temperature and humidity sensor 28 is fixedly installed on the inner side wall of the rectangular frame 23. The temperature and humidity sensor 28, the heating wire 210, and the fan 22 are electrically connected through a controller. A drawer slot 24 is provided on one side of the rectangular frame 23. The drawer frame 25 is inserted and removed from the rectangular frame 23 through the drawer slot 24. A canopy 4 is fixedly installed on the top of the low-voltage cabinet body 1. The canopy 4 is located directly above the rectangular frame 23.

[0034] The low-pressure cabinet with dehumidification device provided by this utility model can ventilate and dehumidify the interior of the low-pressure cabinet body 1 by starting the fan 22 and blowing air into the low-pressure cabinet body 1.

[0035] While the fan 22 blows air, the air passes through the mesh 26, the moisture-absorbing cotton 27 and the filter 29. The mesh 26 and the filter 29 are used to filter and block particles of all sizes, and the moisture-absorbing cotton 27 is used to absorb the moisture in the air, effectively preventing the moisture in the air from entering the interior of the low-pressure cabinet body 1.

[0036] The temperature and humidity sensor 28 is used to detect the humidity in the air. If the temperature and humidity sensor 28 detects that the air filtered by the moisture-absorbing cotton 27 still does not meet the set standard, the information is transmitted to the controller. The controller controls the heating wire 210 to start, which heats the air and dries the moisture in the air, thereby achieving the purpose of drying the air and dehumidifying it.

[0037] Example 2

[0038] Based on Embodiment 1, this embodiment includes: an exhaust mechanism 3, which is disposed on both sides of the low-voltage cabinet body 1. The exhaust mechanism 3 includes a fixed frame 31 fixedly installed on both sides of the low-voltage cabinet body 1, multiple rotating rods 32 rotatably connected inside the fixed frame 31 from top to bottom, a swing plate 33 fixedly installed on the multiple rotating rods 32, a mounting shell 34 fixedly installed on one side of the fixed frame 31, a motor 35 fixedly installed on one side of the mounting shell 34, the motor 35 being electrically connected to a controller, one end of the multiple rotating rods 32 rotatably passing through the fixed frame 31 and fixedly connected to a double-groove synchronous pulley, and the double-groove synchronous pulleys being tensioned and connected by a synchronous belt, the output end of the motor 35 being fixedly connected to the shaft of the double-groove synchronous pulley, multiple exhaust holes 36 being opened through between the low-voltage cabinet body 1 and the fixed frame 31, and a stainless steel mesh plate 37 being fixedly installed inside the fixed frame 31.

[0039] The technical solution provided in this embodiment is as follows: the exhaust hole 36 is used to exhaust the gas inside the low-pressure cabinet body 1. The motor 35 is started and drives the double-groove synchronous wheel to rotate. Under the action of the synchronous belt, multiple rotating rods 32 are rotated, so that the swing plate 33 swings inside the fixed frame 31 to swing and discharge the air discharged from the exhaust hole 36, effectively drying and dehumidifying the exhaust air around the low-pressure cabinet body 1, thereby maintaining the dryness around the low-pressure cabinet body 1.

[0040] The stainless steel mesh 37 is used to prevent external dust from entering the interior of the low-voltage cabinet body 1 when no air is being vented.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
