Problems solved by technology
[0003] There are usually multiple electrical components installed in the power distribution cabinet, which will generate a lot of heat during operation. In areas with high air humidity, after being heated, the hot and humid air in the switch cabinet meets the inner wall of the switch cabinet with a lower temperature. Due to the temperature difference, The hot and humid air will liquefy on the inner wall and top of the power distribution cabinet, resulting in condensation. When the condensation is severe, the condensed dew will drip on the electrical components in the switch cabinet, causing damage to the electrical components and causing the use of the power distribution cabinet. lower life expectancy

Embodiment 1
[0047] see Figure 1-3 , an external dehumidification type power distribution cabinet, including a cabinet body 1, a cabinet door 2 is installed on the cabinet body 1, an external display groove 7 is dug in the middle part of the cabinet door 2, and the mouth of the external display groove 7 facing outward is fixedly connected with a colored The change plate 3, the display groove 7 facing the mouth of the cabinet body 1 is clamped with the ball release display plate. When the color change plate 3 is obviously discolored, the staff can directly remove the entire ball release display plate and replace it with a new one. The display board for putting the ball.
[0048] see Figure 4-5 , the outer display board for putting the ball includes a bearing plate 4 that is clamped with the outer display groove 7, a plurality of pre-damp guide rods 6 that are fixed through the load board 4, and a pre-damp guide rod 6 that is connected to the end of the pre-damp guide rod 6 toward the ins...

The invention discloses an external display type dehumidification type power distribution cabinet, belonging to the field of power distribution cabinets. An external display type dehumidification type power distribution cabinet can effectively absorb the hot and humid air in the cabinet through the setting of a ball-releasing external display board. As the moisture absorbed is more and more, the free-running ball gradually separates from the pre-guided wet rod. On the one hand, the free-running ball is in a free state and gradually floats upward and approaches The top of the power distribution cabinet can effectively absorb the condensation on the top of the power distribution cabinet. Compared with the prior art, it can effectively avoid the phenomenon of condensation dripping on its own, effectively reduce its damage to electronic components, and effectively prolong the life of the power distribution cabinet. On the other hand, the end of the pre-guide wet rod is exposed, which continues to absorb moisture and gradually transfer it into the water-changing ball, which makes the water-changing ball change color, and visually reminds the staff that there is condensation in the cabinet, further reducing the damage caused by condensation.
Description
technical field [0001] The invention relates to the field of power distribution cabinets, more specifically, to an external dehumidification type power distribution cabinet. Background technique [0002] Power distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), which are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. [0003] There are usually multip...
