[0028] A multi-functional switchgear observation window, such as Figure 1-9 As shown, it includes a mounting frame 1, an observation component 2, an exchange component 3, an air guide cylinder 3013, a second limiting plate 3018, and an elastic cloth 3023; the observation component 2 is connected to the mounting frame 1; the exchange component 3 is connected to the observation component 2; the exchange component 3 is connected to the mounting frame 1; the air guide cylinder 3013 is connected to the exchange component 3; the second limiting plate 3018 is connected to the air guide cylinder 3013; and the elastic cloth 3023 is connected to the exchange component 3.

A number of equally spaced triggers 3019 are fixedly connected to the plate 3018; two symmetrical elastic elements 3020 are fixedly connected to the lower part of the first connecting plate 3016; a second connecting plate 3021 is fixedly connected to each of the two elastic elements 3020 on their opposing sides; the two second connecting plates 3021 are slidably connected to the first connecting plate 3016; a roller 3022 is rotatably connected to each of the two second connecting plates 3021 on their opposing sides; the two second connecting plates 3021 are fixedly connected to an elastic cloth 3023; a number of equally spaced nozzles 3024 are fixedly connected to the rubber tube 3010, and the nozzles 3024 are arranged symmetrically in two groups.

[0035] The inside of the drying tube 305 is filled with desiccant.

[0036] The detection head 3011 is an odor sensor used to detect odors in the air.

[0037] The nozzle 3024 located below has a sensor-operated valve inside.

[0038] First, the staff installs the observation window of the multi-functional switchgear on the switchgear. Then, they control the operation of the observation window. During operation, the control motor 303 drives the fan 3012 to rotate, drawing air into the connecting cylinder 301. During this process, the air from inside the switchgear enters the connecting cylinder 301 through the air guide 3013. Meanwhile, the detection head 3011 inside the connecting cylinder 301 detects the drawn air to check for any unusual odors, thus determining if the cable joints inside the switchgear are overheating and producing an odor. When an odor is detected, the detection head 3011 triggers an external alarm to sound an alarm. During the process, the first electric valve 302 is closed to seal the switch cabinet from the outside, while the second electric valve 306 is opened. This allows air drawn into the connecting cylinder 301 to enter the drying tube 305 through the connecting pipe 304. At the same time, the desiccant in the drying tube 305 removes moisture from the air. The dried air is then introduced into the first air guide pipe 307 through the second electric valve 306 and flows into the rubber tube 3010, causing the rubber tube 3010 to expand and seal the connection between the mounting bracket 1 and the mounting frame 202. Then, the dried air in the rubber tube 3010 is sprayed out through the upper nozzle 3024 to dry the air in the switch cabinet and prevent it from becoming damp.

[0039] During the use of the switch cabinet, fog inevitably adheres to the inner surface of the tempered glass 203 during the opening and closing process, affecting the use of the observation window. During this process, the electric slider 3015 slides downwards on the electric slide rail 3014. The electric slider 3015 drives the first connecting plate 3016 to slide downwards. The first connecting plate 3016 drives its connected components downwards, namely, the scraper 3017, the second limit plate 3018, the trigger 3019, the elastic element 3020, the second connecting plate 3021, the roller 3022, the elastic cloth 3023, and the nozzle 3024 to move downwards. This causes the scraper 3017 and the second connecting plate 3021 to move downwards, scraping the tempered glass 203. The condensation on the inner surface of the tempered glass 203 forms water droplets that adhere to the scraper 3017 and the second connecting plate 3021 and flow downwards. When the first connecting plate 3016 contacts the rubber strip 207, the condensed water droplets move to the bottom of the tempered glass 203. During this process, the condensed water droplets flow downwards along the protective net 205 and enter the drain outlet 202a. At the same time, the water droplets on the scraper 3017 and the second connecting plate 3021 flow along the first limiting plate 206 into the drain outlet 202a. The water droplets in the drain outlet 202a flow into the drain hole 202b opened in the mounting frame 202, and the water droplets are collected by an external extraction device to facilitate the use of the observation window.

[0040] During the operation of the switchgear, a cable connector inside the switchgear spontaneously combusted due to partial damage while energized. If no personnel were present during this process, the switchgear's built-in sensor detected the internal combustion and immediately triggered an alarm. Simultaneously, the drive unit of the defluorination switchgear controlled the valve built into the gas storage tank 308 to open, connecting the tank to the second gas guide pipe 309. Carbon dioxide from the tank then flowed through the second gas guide pipe 309 into the rubber hose 3010 and was sprayed from the nozzle 3024 above, allowing the carbon dioxide to enter the switchgear. During this process, the control motor 303 drove the fan 3012 to extract air from the switchgear. The air then enters the connecting cylinder 301. During this process, the first electric valve 302 is opened while the second electric valve 306 is closed, allowing air to flow outward. The extracted air is discharged through the first electric valve 302. An external purification device is then connected to the first electric valve 302 to discharge and purify the air. During this process, carbon dioxide sprayed from the upper nozzle 3024 fills the upper half of the switch cabinet and then flows downward. Simultaneously, the electric slider 3015 moves the first connecting plate 3016 downward, which in turn moves its connected components downward, causing the second limiting plate 3018 to move downward. 18 drives trigger 3019 to move downwards. When it reaches the lowest point, trigger 3019 aligns with the nozzle 3024 located below, causing the built-in sensing valve of the nozzle 3024 to open, allowing carbon dioxide to be ejected from the nozzle 3024. The ejected carbon dioxide is limited by the second limiting plate 3018, causing the carbon dioxide to flow downwards. During this process, the two rollers 3022 first contact the air guide cylinder 3013, and then, during a further downward movement, the two rollers 3022 roll against the air guide cylinder 3013, squeezing the two second connecting plates 3021 and compressing the two elastic elements 3020. During this process, the elastic cloth 302... 3. Covering the surface of the air guide cylinder 3013, when the two rollers 3022 move to the bottom of the air guide cylinder 3013, the two elastic elements 3020 rebound and push the two second connecting plates 3021 to move towards each other. The two second connecting plates 3021 drive the two rollers 3022 to move towards each other and stretch the elastic cloth 3023, so that the elastic cloth 3023 fits against the air guide cylinder 3013 to block the holes on the air guide cylinder 3013. At the same time, the motor 303 is controlled to stop running to isolate the switch cabinet from the outside air, so that the carbon dioxide concentration in the switch cabinet increases, thereby reducing the fire in the switch cabinet and preventing the components in the switch cabinet from burning too quickly and causing danger if the fire is too large when the staff is not present.
