[0002] During the use of energy-saving substation cabinets, humid gas is easy to enter the inside of the substation cabinet, and these humid gases are easy to damage the electrical components inside the substation cabinet. Therefore, the staff needs to discharge the humid gas in time. The common substation cabinet dehumidification device is usually composed of a dehumidification bag and a fan. The fan can guide the air into the dehumidification bag, and the dehumidification bag can absorb the humid water vapor in the air;

[0003] This dehumidification device can indeed achieve a good dehumidification effect on the air inside the transformer cabinet, but the staff needs to replace the dehumidification bag regularly. Since the dehumidification bag inside the transformer cabinet is usually embedded in the transformer cabinet, it will be more cumbersome to disassemble and assemble the dehumidification bag, thereby increasing the maintenance cost of the transformer cabinet. At the same time, when the dehumidification bag inside the transformer cabinet absorbs more water vapor, if the staff cannot replace the dehumidification bag in time, the water vapor inside the dehumidification bag will liquefy and flow back into the transformer cabinet, which will also damage the electrical components inside the transformer cabinet.

DETAILED DESCRIPTION

[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1-Figure 7 The dehumidification device for an energy-saving transformer cabinet shown in the figure comprises a cabinet structure 1 and an exhaust fan 2 detachably connected to the cabinet structure 1, a shell 4 detachably connected to the lower part of the inner cavity of the cabinet structure 1, and a condensation structure detachably connected to the interior of the shell 4;

[0027] The condensation structure includes a first condensation tube 11 and a second condensation tube 17 distributed inside the shell 4, and an external shell 6. The first condensation tube 11 is connected to the second condensation tube 17 through an arc-shaped connecting tube 20. An infusion cavity 18 and a liquid return cavity 19 are provided on the external shell 6. The second condensation tube 17 is connected to the infusion cavity 18 on the external shell 6 through a connecting tube 16. The first condensation tube 11 is connected to the liquid return cavity 19 on the external shell 6 through a connecting tube 16. The infusion cavity 18 and the liquid return cavity 19 on the external shell 6 are connected to an external refrigeration device.

[0028] The exhaust fan 2 can discharge the air inside the cabinet structure 1 to the outside. At this time, the interior of the cabinet structure 1 and the shell 4 is in a negative pressure state, and the external air can contact the first condenser 11 and the second condenser 17 inside the shell 4. At this time, the water vapor in the air can be liquefied inside the shell 4. The external refrigeration equipment can be an existing structure on the market. The role it plays in this document is to cool the first condenser 11 and the second condenser 17.

[0029] The receiving end of the shell 4 penetrates the cabinet structure 1, and a filter plate 3 is embedded in the receiving end of the shell 4. The filter plate 3 is fixedly connected to the cabinet structure 1 through mounting bolts 23. A top plate 5 is embedded in the output end of the shell 4, and air outlet holes 8 are opened on the top plate 5 at equal intervals.

[0030] External air can pass through the filter plate 3 to enter the interior of the housing 4 , and the external air dehumidified by the housing 4 can pass through the top plate 5 and the air outlet 8 .

[0031] The arc-shaped pipe 20 is fixedly connected to the inner wall of the shell 4 through the mounting plate 10, and the second condenser pipe 17 is fixed to the inner wall of the shell 4 through the support frame 21. The inner wall of the shell 4 is fixedly connected to the support frame 21 and is provided with an inclined plate 9. The inner wall of the shell 4 is provided with a bent portion 32 near the bent portion of the second condenser pipe 17.

[0032] The low temperature generated by the second condenser 17 can be transmitted to the inclined plate 9 through the support frame 21. When the air filtered by the filter plate 3 enters the interior of the shell 4, the air filtered by the filter plate 3 can contact the inclined plate 9, and the water vapor in the air will liquefy on the inclined plate 9.

[0033] The bottom surface of the inner wall of the shell 4 is provided with a guide portion 24, and a stopper 12 is fixedly connected to the portion of the guide portion 24 close to the filter plate 3, and an inclined portion 25 is provided on the side of the stopper 12 close to the filter plate 3, and an arc-shaped notch 22 is provided on the side of the stopper 12 close to the external shell 6, and a drain pipe 13 passes through the shell 4, and the drain pipe 13 is close to the stopper 12, and a one-way valve is connected to the output end of the drain pipe 13;

[0034] When external air passes through the filter plate 3 and enters the interior of the shell 4, the inclined portion 25 on the block 12 can guide the external air. At this time, the external air can be liquefied on the first condenser 11 and the second condenser 17 and the inclined plate 9. The liquefied water can be transferred to the drain pipe 13 through the guide portion 24. At the same time, the arc-shaped notch 22 can shield the water, so that the liquefied water from the external air can be transferred through the drain pipe 13. Since a one-way valve is connected to the drain pipe 13, external air can be prevented from entering the interior of the shell 4.

[0035] The bottom surface of the top plate 5 is fixedly connected to a mounting strip 29 via a connecting bolt 27, and the mounting strip 29 is rotatably connected to a scraper frame 14 via a connecting hinge 26. A connecting spring 28 is fixed between the mounting strip 29 and the scraper frame 14, and a scraper plate 7 is fixedly connected to the scraper frame 14. The scraper frame 14 is sleeved on the first condenser tube 11 and the second condenser tube 17, and arc-shaped scraping grooves 31 are provided at the parts of the scraper frame 14 and the scraper plate 7 near the second condenser tube 17, and the scraper frame 14 and the scraper plate 7 can scrape the water on the first condenser tube 11 and the second condenser tube 17 through the arc-shaped scraping grooves 31;

[0036] When external air enters into the interior of the shell 4, the external air can drive the scraper frame 14 and the scraper 7 to flip over. At this time, the scraper frame 14 and the scraper 7 can scrape the liquefied water in the first condenser tube 11 and the second condenser tube 17. The water collected in the arc scraping groove 31 can be transferred to the guide part 24 through the arc guide block 30.

[0037] The lower ends of the scraper frame 14 and the scraper plate 7 are fixedly connected with an arc-shaped guide block 30, and the upper part of the second condenser tube 17 is fixedly connected with an arc-shaped penetration rod 15, and the upper part of the arc-shaped penetration rod 15 can penetrate the top plate 5 through the air outlet hole 8;

[0038] When the external air can drive the scraper frame 14 and the scraper plate 7 to turn over, the arc-shaped penetration rod 15 can pass through the air outlet 8 and the top plate 5, thereby preventing the air outlet 8 from being blocked.

[0039] Working principle: When the exhaust fan 2 on the cabinet structure 1 is in use, the interior of the cabinet structure 1 and the shell 4 is in a negative pressure state, and when the external air contacts the first condensation tube 11 and the second condensation tube 17, the water vapor in the external air will be liquefied. At the same time, when the water vapor in the external air contacts the inclined plate 9, the water vapor can also be liquefied on the inclined plate 9. When the external air drives the scraper frame 14 and the scraper 7 to flip, the scraper frame 14 and the scraper 7 can scrape the liquefied water on the first condensation tube 11 and the second condensation tube 17. At this time, the liquefied water can be transferred to the drain pipe 13 through the guide part 24, so as to remove the humid gas in the external air. The dehumidified external air can contact the electrical components inside the cabinet structure 1, and then the external air is discharged through the exhaust fan 2. It should be added that the working mode of the exhaust fan 2 is intermittent. When the external air intermittently drives the scraper frame 14 and the scraper 7 to flip, the arc-shaped penetrating rod 15 can repeatedly pass through the air outlet 8 and the top plate 5 to avoid blockage of the air outlet 8.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
