[0032] Specifically, the rain shield 4 can effectively prevent rainwater from directly invading the cabinet body 1. The solar panels 5 can absorb solar energy and convert it into electrical energy, which is stored in the storage battery 6. By turning on the dehumidifier 7, dry gas is delivered to the inside of the cabinet body 1 through the air jet nozzle 8, which can effectively reduce the humidity inside the ring main switchgear. The humid gas inside it will be discharged from the inside of the cabinet body 1 by the small fans 12 through the air outlet holes 10. To prevent the humid gas from flowing back, desiccant boxes 13 are also installed in the air outlet holes 10 to absorb some humid water mist and dust, preventing the main unit 9 from short-circuiting when encountering water mist.

[0033] Refer to Figure 1 , Figure 2 and Figure 3 , the heat dissipation device 2 includes two air ducts 201. Heat dissipation fans 202 are rotatably connected to both the left and right sides of the main unit 9. Slide grooves 203 are fixedly connected to the bottoms of both the left and right sides of the cabinet body 1. Slide covers 204 are arranged on the inner walls of the two slide grooves 203.

Gear motors 205 are fixedly connected to the middle parts of both the left and right sides of the cabinet body 1. Rack bars 206 are fixedly connected to the adjacent sides of the two slide covers 204. The two gear motors 205 are meshed with the two rack bars 206. Baffle plates 207 are fixedly connected to the upper middle parts of both the left and right sides of the cabinet body 1;

[0034] Specifically, air ducts 201 are opened on both the left and right sides of the cabinet body 1 for installing heat dissipation fans 202. By allowing air to enter from one side and exit from the other side, the heat inside the ring main switchgear can be effectively discharged. The structure composed of the slide grooves 203 and the slide covers 204 can close the air ducts 201 when cooling is not required, preventing dust and other pollutants from entering the inside of the ring main switchgear. By driving the rack bars 206 with the gear motors 205, the opening and closing of the slide covers 204 can be conveniently controlled. The baffle plates 207 prevent the slide covers 204 from rising too high and falling off.

[0035] Refer to Figure 1 andFigure 2 On the upper and lower sides of the front end of the left side of the cabinet body 1, rotating shafts 14 are rotatably connected, and insulating doors 15 are rotatably connected to the front sides of the outer walls of the two rotating shafts 14; a sealing ring 16 is fixedly connected to the rear side of the insulating door 15; an insulating handle 17 is fixedly connected to the front side of the insulating door 15;

[0036] Specifically, the insulating door 15 can be opened and closed through the rotating shaft 14. The main function of the insulating door 15 is to protect the internal equipment of the ring main unit, prevent personnel from directly contacting the live parts, thereby ensuring operation safety.

A sieve 20 is arranged in the middle of the bottom plate 19; at the four corners of the bottom wall of the bottom plate 19, columns 21 are fixedly connected. The bottom ends of the multiple columns 21 are fixedly connected with anti-slip pads 22; the top shape of the rain shield 4 is a pyramid;

[0038] Specifically, the function of the spacer plate 18 is to provide a space between the bottom wall of the cabinet body 1 and the bottom plate 19 as a heat dissipation channel, which helps the heat inside the ring main unit to dissipate. The sieve 20 is installed in the middle of the bottom plate 19. The function of the sieve 20 is to filter and block large particle impurities in the external environment, such as dust and sand, to prevent them from entering the ring main unit and affecting the normal operation of the equipment.

[0039] Working principle: In bad weather, the rain shield 4 can effectively prevent rainwater from directly invading the cabinet body 1. Since water mist will enter the interior of the cabinet body 1 through the surrounding area, the solar panel 5 can absorb solar energy and convert it into electrical energy, which is stored in the storage battery 6. When in use, the dehumidifier 7 is turned on, and dry gas is delivered into the cabinet body 1 through the air jet nozzle 8, which can effectively reduce the humidity inside the ring main unit, preventing electrical components from malfunctioning or short-circuiting due to moisture. The humid air inside it will be discharged from the interior of the cabinet body 1 through the air outlet hole 10 by the small fan 12. To prevent the return of humid air, a desiccant box 13 is also installed in the air outlet hole 10 to absorb some humid water mist and dust, preventing the main unit 9 from short-circuiting when encountering water mist, etc., improving the reliability, safety and operating efficiency of the ring main unit. And in summer, due to long-term exposure to high temperatures, it is easy to cause the main unit 9 to overheat. Wind tunnels 201 are opened on the left and right sides of the cabinet body 1 for installing cooling fans 202. By allowing air to enter from one side and exit from the other side, the heat inside the ring main unit can be effectively discharged, preventing the equipment from overheating. The structure composed of the sliding groove 203 and the sliding cover 204 can close the wind tunnel 201 when cooling is not required, preventing dust and other pollutants from entering the interior of the ring main unit. By driving the rack 206 with the gear motor 205, the opening and closing of the sliding cover 204 can be conveniently controlled. The baffle 207 prevents the sliding cover 204 from rising too high and falling, improving safety.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
