Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Example: A moisture-proof high-voltage distribution cabinet, such as Figures 1-7 As shown, the cabinet includes a cabinet body 1, a cabinet door 2, a first handle 7, a first fan 11, a ventilation panel 18, connecting posts 20, a second fan 21, a heating wire 22, and a dehumidification switch 23. The cabinet body 1 is rotatably connected to the front of the cabinet door 2, and the first handle 7 is fixedly connected to the right side of the cabinet door 2. The first fans 11 are installed on both sides of the upper part of the cabinet body 1. Several second slots 19 are opened on the lower rear side of the cabinet body 1. The ventilation panel 18 is fixedly connected to the lower part of the cabinet body 1. Eight connecting posts 20 are fixedly connected to the ventilation panel 18. The eight connecting posts 20 are symmetrical in pairs. A second fan 21 is fixedly connected to every four connecting posts 20. A heating wire 22 is fixedly connected to the upper part of each of the two second fans 21. A dehumidification switch 23 is installed at the lower part of the cabinet door 2. The dehumidification switch 23 is electrically connected to the first fan 11, the second fan 21, and the heating wire 22. The dehumidification switch 23 can simultaneously turn on and off the first fan 11, the second fan 21, and the heating wire 22.
[0025] like Figure 2 , Figure 4 and Figure 6 As shown, it also includes a drawer box 13, a second handle 15, a sponge block 16, and a desiccant pack 17. The drawer box 13 is slidably connected to the lower part of the cabinet door 2. The drawer box 13 is located below the ventilation plate 18. Several first slots 14 are opened on the rear side of the drawer box 13. The first slots 14 and the second slots 19 correspond to each other. The second handle 15 is fixedly connected to the front side of the drawer box 13. The sponge block 16 is slidably placed on the rear inner side of the drawer box 13. The desiccant pack 17 is slidably placed on the front inner side of the drawer box 13. The sponge block 16 and the desiccant pack 17 are replaceable.
[0026] like Figures 1-3 As shown, it also includes a baffle plate 12. The baffle plate 12 is fixedly connected to the top of the first fan 11. The baffle plate 12 can prevent dust from entering the first fan 11 and the cabinet 1.
[0027] like Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, it also includes casters 8. Casters 8 are installed around the bottom of the cabinet 1 to allow the distribution cabinet to move.
[0028] like Figure 1 and Figure 3 As shown, it also includes an external light switch 4, an internal light switch 5, external light blocks 6, a first internal light 9, and a second internal light 10. The external light switch 4 and the internal light switch 5 are installed on the upper front side of the cabinet door 2. Four external light blocks 6 are installed on the upper front side of the cabinet door 2. The first internal light 9 is installed on the upper inner side of the cabinet body 1. The second internal light 10 is installed on both the left and right sides of the inner side of the cabinet body 1. The external light switch 4 is electrically connected to the four external light blocks 6. Pressing the external light switch 4 can turn the four external light blocks 6 on and off. The internal light switch 5 is electrically connected to the first internal light 9 and the two second internal lights 10. Pressing the internal light switch 5 can turn the first internal light 9 and the two second internal lights 10 on and off.
[0029] like Figure 1 As shown, it also includes an observation block 3. The observation block 3 is fixedly connected to the middle of the cabinet door 2. The observation block 3 is made of transparent material, and the internal situation can be viewed through the observation block 3.
[0030] First, press the external light switch 4 and the internal light switch 5 to turn on the four external light blocks 6, the first internal light 9, and the two second internal lights 10. Then, observe the internal situation through the observation block 3. If it is daytime, there is no need to turn them on. Observe whether there is a problem with the circuit. If there is a problem, open the cabinet door 2 through the first handle 7 for repair. After the repair is completed, close the cabinet door 2 through the first handle 7. Because the bottom of the cabinet 1 is equipped with casters 8, when it is necessary to move the power distribution cabinet, the cabinet 1 can be pushed to move it.
[0031] When the air is humid, due to the enclosed environment, temperature fluctuations, and humidity of the high-voltage distribution cabinet, dehumidification switch 23 is activated to prevent moisture absorption. The first fan 11, the second fan 21, and the heating wire 22 start operating simultaneously. The first fan 11 exhausts internal air, while the second fan 21 draws external air in through the second slot 19 at the rear of the cabinet 1, then through the first slot 14 into the drawer 13. After being filtered by the sponge block 16 and the desiccant 17, the air enters the cabinet 1 through the heating wire 22, drying the air within the cabinet 1. The heated air then dries the air in the cabinet. 1. As the temperature rises, the moisture in the air inside the cabinet 1 evaporates and is discharged through the first fan 11, achieving a dehumidification effect. At the same time, the baffle 12 on the first fan 11 can prevent dust from entering. After a certain period of time, the dehumidification switch 23 is turned off, and the first fan 11, the second fan 21 and the heating wire 22 stop operating simultaneously. Then, press the external light switch 4 and the internal light switch 5 to turn off the four external light blocks 6, the first internal light 9 and the two second internal lights 10. After a period of use, the drawer 13 can be pulled out through the second handle 15 to replace the sponge block 16 and the desiccant pack 17.
