Abstract
Description
Technical Field
[0001] The utility model relates to the field of transformer substation devices, in particular to an automatic anti-condensation and dehumidification power prefabricated cabin transformer substation. Background Art
[0002] For prefabricated cabin substations operating in high-humidity areas, if the cabin temperature is close to the dew point temperature (small temperature difference) or the absolute humidity in the cabin is high, condensation will occur under the combined effect of humidity and temperature.

At the same time, if the electrical equipment in the cabin operates for a long time in such an environment, the internal metal structural parts of the equipment will gradually rust and reduce its mechanical structural strength. The wiring in the cabin will also corrode, age, and mildew, which will have a significant impact on the safe and stable operation of the smart substation. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-6 The utility model discloses an automatic anti-condensation dehumidification electric power prefabricated cabin substation, comprising a first prefabricated cabin body 2, a second prefabricated cabin body 3 and a base 1, wherein the first prefabricated cabin body 2 and the second prefabricated cabin body 3 are hinged with cabinet doors 14, the first prefabricated cabin body 2 is fixedly mounted on the base 1, the second prefabricated cabin body 3 is fixedly mounted on the top of the first prefabricated cabin body 2, a platform area is reserved on the top of the first prefabricated cabin body 2, a sloping roof board 4 is installed on the top side of the first prefabricated cabin body 2 and the second prefabricated cabin body 3, a guide layer 8 is provided on the inner side of the sloping roof board 4, and the guide layer 8 is connected to the first prefabricated cabin body 2. The first prefabricated cabin 2 and the second prefabricated cabin 3 are connected to the inner cavity of the second prefabricated cabin 3. A drying layer is provided at the bottom of the first prefabricated cabin 2 and the second prefabricated cabin 3. A dehumidification device 11 and a heating device are provided in the drying layer. A plurality of ventilation pipes 5 are provided on the side walls of the first prefabricated cabin 2 and the second prefabricated cabin 3. One end of the ventilation pipe 5 is located on the outside of the first prefabricated cabin 2 and the second prefabricated cabin 3, and the other end of the ventilation pipe 5 is connected to the drying layer. The dehumidification device 11 is used to dehumidify the air introduced by the ventilation pipe 5. The heating device is used to ensure the constant temperature of the inner cavity of the first prefabricated cabin 2 and the second prefabricated cabin 3.
[0025] The preferred solution of the above-mentioned automatic anti-condensation and dehumidification prefabricated power cabin substation is the design of two prefabricated cabins. The top of the first prefabricated cabin 2 is designed as a flat-top structure, and a slope is provided on the inner side. This structure facilitates entering the second prefabricated cabin 3 from the top of the first prefabricated cabin 2, and also facilitates the diversion and discharge of air from the top of the inner cavity of the first prefabricated cabin 2, thereby facilitating the air circulation inside it.
[0026] The top of the second prefabricated cabin 3 is a human-shaped roof, which is an integrated structure with the sloping roof 4 of the second prefabricated cabin 3. This design enhances the air guidance effect in the inner cavity of the second prefabricated cabin 3, and also increases the space inside the second prefabricated cabin 3.
[0027] The preferred solution of the above-mentioned automatic anti-condensation dehumidification prefabricated power cabin substation is the innovation of the dehumidification device 11, which includes a frame, a dehumidification fiber net 9 and a desiccant 10. The dehumidification fiber net 9 is embedded in the bottom and middle of the frame, and the desiccant 10 is filled between the two layers of dehumidification fiber net 9. This can more efficiently absorb and remove moisture in the air introduced into the first prefabricated cabin body 2 and the second prefabricated cabin body 3 by the drying layer.
[0028] The preferred solution of the above-mentioned automatic anti-condensation and dehumidification prefabricated power cabin substation is the optimization of the heating device, which includes an electric heating plate 7 and an induced draft fan 6. The drying layer is heated by the electric heating plate 7, and the hot air is then transported to the inner cavity of the first and second prefabricated cabins 3 by the induced draft fan 6 to ensure that the interior is always kept dry. The filter layer is arranged on the side of the inner cavity of the first prefabricated cabin 2 and the second prefabricated cabin 3, thereby ensuring that the air inside the first prefabricated cabin 2 and the second prefabricated cabin 3 circulates without affecting the installation of the substation electrical equipment.
[0029] The preferred solution of the above-mentioned automatic anti-condensation dehumidification prefabricated power cabin substation is a humanized design. A climbing ladder 15 is provided on the side wall of the first prefabricated cabin body 2 and wrapped with an anti-slip rubber pad to increase the safety of personnel going up and down. The dehumidification device 11 can be slidably installed in the dry layer for easy maintenance and movement. A slide groove 13 is provided on the side wall of the dry layer. The side of the frame is slidably connected to the slide groove 13 through a slide rod, so that the dehumidification device 11 can be easily moved in the dry layer. When the dehumidification device 11 is full of adsorbed moisture, it is convenient to replace it.
[0030] The design of the sloped roof 4 in the automatic anti-condensation dehumidification power prefabricated cabin substation can effectively guide rainwater to be discharged from the top of the first prefabricated cabin and the second prefabricated cabin body 3 to prevent water accumulation. At the same time, the guide layer 8 inside the broken board also serves as an air guide channel to help the internal air circulation. The ventilation pipe 5 structure can continuously introduce external fresh air into the dry layer, and the introduced air is dehumidified by the dehumidification device 11 to reduce the humidity. The heating device heats the cabin and the air introduced into the dry layer to ensure the constant temperature state of the inner cavity of the first prefabricated cabin and the second prefabricated cabin body 3 to prevent the generation of condensation. This combination can maintain a dry and stable temperature environment in the two prefabricated cabins.
