Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a waterproof and dehumidifying power distribution cabinet for factories. Background Art

[0002] High-voltage distribution cabinet refers to the equipment used for switching, controlling or protecting in power generation, transmission, distribution, power conversion and consumption of power system. It mainly includes high-voltage circuit breakers, high-voltage isolating switches and grounding switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switch cabinets. The high-voltage switch manufacturing industry is an important part of the power transmission and transformation equipment manufacturing industry and occupies a very important position in the entire power industry.

[0003] At present, most of the high-voltage distribution cabinets on the market lack waterproof and dehumidification structures, and the waterproof effect is poor, which makes it easy for rainwater to penetrate into the cabinet during outdoor use on rainy days, thus affecting the electrical components in the cabinet. It is very unsafe to use and difficult to adapt to the outdoor use environment. In addition, general factories are relatively remote and the environment is usually humid. In the absence of a dehumidification structure, the electrical components are prone to aging, affecting their service life and easily causing danger.

[0004] A patent CN212991610U is disclosed in the prior art. The solution includes a cabinet body, and a first rain shield and a second rain shield are fixedly provided on both sides of the top of the cabinet body, and support tubes are fixedly provided on both sides of the second rain shield. Piston rods are slidably provided inside the two support tubes, and an extension plate is slidably provided inside the second rain shield. Both ends of one side of the extension plate are fixedly connected with connecting blocks. The beneficial effects of the utility model are as follows: air is blown into the interior of the cabinet body by a fan, and then converted into hot air through a heating wire to dry the interior of the cabinet body. Through the partitions provided, the electrical components are kept away from the ground, reducing the impact of ground moisture on the electrical components. Through the air holes opened at the bottom of the partitions, the humid air inside the cabinet passes through the bottom of the cabinet and then is discharged to the outside through the vents. At the same time, the hot air generated by the heating wire dries the ground and reduces the humidity inside the cabinet.

[0005] As the device is used, the shortcomings of the technology are gradually exposed, mainly in the following aspects:

[0006] First, when the existing power distribution cabinet is used outdoors, rainwater easily enters the cabinet through the ventilation holes on the top. If the ventilation holes on the top are blocked, the heat dissipation of the electrical components in the power distribution cabinet will be affected.

[0007] Second, when the existing power distribution cabinet is used outdoors, when the outside air humidity is high, it will cause high moisture inside the power distribution cabinet, affecting the working stability of the electrical components.

[0008] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
