Technical Field

[0001] The utility model relates to the technical field of substation dehumidification, in particular to a dehumidification device for a substation. Background Art

[0002] Indoor substations have relatively high temperature and humidity due to dense equipment and poor ventilation conditions. Especially in the southern region, when the humidity is high after rain and during the rainy season, condensation water droplets will form on the substation electrical cabinet housing and internal mechanisms. When accumulated to a certain extent, water will drip, which may cause partial discharge or short circuit, leading to safety accidents. Therefore, when the indoor humidity is high, the indoor substation must be dehumidified.

[0003] However, in the prior art, dehumidification devices for substations generally use exhaust fans and heating rods to achieve the purpose of dehumidification, and use filter plates to filter dust in the air. Therefore, workers need to clean the filter plates regularly to prevent them from being blocked, which increases the labor intensity of the workers. At the same time, the filter plates in some dehumidification devices for substations are inconvenient to install and disassemble. Utility Model Content

[0027] Specifically: the output end of the bidirectional motor 203 drives the screw rod 202 to rotate. Since the scraper 201 is threadedly connected to the screw rod 202, the scraper 201 can be moved. One side of the scraper 201 fits against the surface of the filter plate 303, and can scrape off the dust accumulated on the surface of the filter plate 303. This design reduces the frequency of staff cleaning the filter plate 303 and reduces the labor intensity of the staff; bend one end of the two blocks 301, and a part of the filter plate 303 is pushed out of the inside of the filter plate movable groove 105, and the filter plate 303 is pulled out from the inside of the filter plate movable groove 105. When installing, the filter plate 303 is inserted into the inside of the filter plate movable groove 105. The block 301 returns to its original state under the action of the elastic force of the spring 2 302 and is limited. This design facilitates the installation and disassembly of the filter plate 303 by the staff.
