Description

Technical Field

[0001] The utility model relates to the field of high-voltage power distribution cabinets, in particular to a high-voltage power distribution cabinet with a dehumidification function. Background Art

[0002] High-voltage and low-voltage distribution cabinets are equipment used for power conversion, control and distribution in power systems. They consist of four main parts: high-voltage room, low-voltage room, control room and operation room. The high-voltage room is mainly used to receive and distribute high-voltage power from the power system, while the low-voltage room is responsible for converting high-voltage power into low-voltage power and supplying it to end users.

[0003] The prior art publication number is: CN211629534U, which discloses a high-voltage power distribution cabinet with moisture-proof function. The bottom end of the power distribution cabinet body is connected to the base through a telescopic mechanism. The base includes a cavity, a through hole and a collecting trough. The cavity is opened inside the base, and the top of the cavity is an arc surface. The through hole is vertically opened on the bottom surface of the base. The through hole connects the cavity with the outside world. The collecting trough is opened on both sides of the cavity. Support blocks are welded on both sides of the bottom surface of the base. The bottom ends of the support blocks are connected to the corrosion-resistant base through a sliding mechanism. The base is used to lift the power distribution cabinet body away from the ground to prevent the bottom of the power distribution cabinet from being damp and corroded. The water vapor evaporated from the ground under the base condenses into water droplets at the top of the cavity. When the water droplets reach a certain mass, they slide down to both sides along the arc surface of the cavity under the action of stress. The collecting trough collects the sliding water droplets. The water pipe outside the collecting trough discharges the water in the trough to other places, thereby reducing the water content of the ground at the power distribution cabinet.

[0004] Through the above settings, the high-voltage distribution cabinet described in the prior art prevents the bottom of the distribution cabinet from getting wet by adjusting the distance between the distribution cabinet body and the ground, which has some effect on moisture-proofing the distribution cabinet. However, the high-voltage distribution cabinet of the prior art solution has the following defects during operation:

[0005] The existing technology achieves moisture-proofing of the distribution cabinet body by adjusting the distance between the distribution cabinet body and the bottom surface. However, when encountering rainy and humid weather, moisture and humidity will still enter the main body of the distribution cabinet through very small gaps. If it cannot be dried in time, the main body of the distribution cabinet will become damp, affecting the parts inside the main body of the distribution cabinet and easily causing damage to the parts. Utility Model Content

[0006] The utility model aims to provide a high-voltage power distribution cabinet with a dehumidification function, which is mainly used to solve the technical problem in the prior art that moisture and humidity can enter the main body of the power distribution cabinet and cannot be dried.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A high-voltage power distribution cabinet with a dehumidification function comprises a power distribution cabinet body, a motor slot is provided at the bottom end of the inner wall of the power distribution cabinet body, an air outlet is provided at the side wall of the power distribution cabinet body, and a fixing slot is provided at the inner wall of the power distribution cabinet body, the fixing slot is communicated with the air outlet, a motor is fixedly connected to the inner wall of the motor slot, a fan blade is fixedly connected to the output end of the motor, a guide shell is fixedly connected to the bottom end of the inner wall of the power distribution cabinet body around the motor slot, a placement slot is symmetrically provided on the upper surface of the guide shell, a first through hole is provided on the bottom surface of the placement slot, a moisture-proof bag is placed inside the placement slot, the first through hole is communicated with the motor slot, an annular slot and a clamping slot are provided on the upper surface of the guide shell around the placement slot, a protective device is installed inside the annular slot, and a cabinet door is hinged on one side of the power distribution cabinet body.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: First, install the moisture-proof filter plate inside the fixed groove, then pinch the pinch block to rotate the cover plate to open the cover plate, remove the cover plate, and then place the moisture-proof bag inside the placement groove, and then rotate the cover plate to connect the threaded ring fixed on the cover plate with the threaded groove, and cover it. When it is necessary to dehumidify the inside of the distribution cabinet in rainy weather, start the motor, the motor drives the fan blades to rotate, and then the wind blown out by the fan blades passes through the first through hole, the second through hole, and the third through hole into the inside of the distribution cabinet for dehumidification.

[0011] 2. Beneficial effects:

[0012] By setting up the motor and the guide shell, when encountering rainy weather, the motor is started, so that when the motor drives the fan blades to rotate, the smell of the moisture-proof bag quickly enters into the interior of the distribution cabinet through the airflow, which has a very good moisture-proof effect on the interior of the distribution cabinet, and can quickly dry the moisture and humidity entering the interior of the distribution cabinet, effectively preventing the moisture and humidity from damaging the parts inside the distribution cabinet.

By providing the protective device, when the motor is started in rainy weather, the moisture-proof bag inside the protective groove can be blocked, which can effectively prevent the moisture-proof bag from flying out under the action of wind, and the moisture-proof inside the distribution cabinet is more durable and effective.

[0014] Preferably, a moisture-proof filter plate is fixedly connected to the inner wall of the fixing groove, and the air outlet corresponds to the moisture-proof filter plate. By providing the moisture-proof filter plate, external moisture can be isolated from the inside of the distribution cabinet to prevent moisture from entering the distribution cabinet.

[0015] Preferably, the upper surface of the guide shell is provided with a plurality of third through holes, and the third through holes are connected to the motor slots. The third through holes can allow airflow to enter the interior of the power distribution cabinet body faster, dry the interior of the power distribution cabinet faster, and prevent moisture from damaging the parts inside the power distribution cabinet.

[0016] Preferably, the first through hole and the third through hole are of the same size, and the second through hole is larger than the first through hole, so that the airflow passing through the placement slot can enter the interior of the power distribution cabinet body faster through the moisture-proof bag, and the moisture-proof effect is better.

[0017] Preferably, an anti-skid pad is fixedly connected to the outer wall of the pinch block to prevent the fingers and the pinch block from slipping when the cover plate is rotated.

[0018] Preferably, a sealing gasket is fixedly connected to one side of the cabinet door corresponding to the main body of the power distribution cabinet. The sealing gasket can effectively prevent moisture and humidity from entering the interior of the power distribution cabinet, thereby preventing moisture from damaging the parts inside the power distribution cabinet.
