Description

Technical Field

[0001] The utility model relates to a ventilation side plate used for power distribution equipment with a high protection level, belonging to the technical field of electrical equipment. Background Art

[0002] Outdoor power distribution equipment requires a higher protection level, reaching IP44 or above to adapt to rainy, snowy weather and windy and sandstorms. However, in order to reduce the temperature rise of the power distribution equipment and reduce condensation, outdoor power distribution equipment is often required to have ventilation capabilities. The high protection level requirements and ventilation requirements are prone to conflict with each other, resulting in the power distribution equipment failing to reach a high protection level. There is an urgent need for equipment that meets ventilation requirements and a high protection level. Utility Model Content

[0003] The purpose of the utility model is to propose a ventilation side plate for power distribution equipment with high protection level, which can meet the requirements of ventilation and high protection level at the same time, in view of the problems existing in the prior art.

[0004] In order to achieve the above purpose, the utility model provides a ventilation side panel for a high protection level power distribution equipment, including a side panel body fixed to the periphery of the power distribution equipment, the surface of the side panel body is provided with evenly distributed ventilation windows, the surface of the ventilation windows facing the inside of the cabinet is fixed with a protective cover plate adapted to the ventilation windows, and a dustproof screen plate and a filter sponge are also fixed between the ventilation windows and the protective cover plate. The above structure can ensure that the side panel meets the requirements of ventilation and high protection level at the same time. High protection level means that the protection level reaches IP44 and above.

[0005] The long side of the side plate body has a folded edge, and the folded edge has a connecting edge folded outwards, which is convenient for assembly with power distribution equipment.

[0006] The ventilation window has a louver air outlet, and energy storage welding nails are arranged around the ventilation window for connecting the dustproof mesh plate and the protective cover plate.

[0007] The surface of the protective cover plate has a reverse louver vent that matches the louver vent, and the two sides of the protective cover plate have extended edges, and the extended edges are provided with fixing holes connected to the energy storage welding nails. A filter sponge is pasted on the back of the reverse louver vent. While the reverse louver vent serves to increase the ventilation channel, it also prevents the long-term accumulated water vapor in the filter sponge from condensing and dripping into the distribution box. The filter sponge has a porosity of up to 97% and has excellent air permeability. It can play a role in dust prevention, ventilation, and splash prevention, further improving the protection level of the distribution equipment.

[0008] The dustproof mesh plate is a metal mesh plate with heat dissipation circular holes evenly distributed on the surface, and the dustproof mesh plate is provided with mesh plate fixing holes connected with energy storage welding nails, so as to ensure ventilation and prevent foreign objects from invading the power distribution equipment.

[0009] The utility model has a simple structure and is easy to use, and has the beneficial effects of simultaneously meeting ventilation requirements and a high protection level, thereby expanding the application scenarios of electrical equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The structure of this embodiment is as follows Figure 1-6As shown, a ventilation side panel for power distribution equipment with a high protection level includes a side panel body 1 fixed to the periphery of the power distribution equipment, a surface of the side panel body 1 facing the outdoors 5 is provided with uniformly distributed ventilation windows 1-1, a protective cover plate 2 adapted to the ventilation windows 1-1 is fixed on the surface 6 of the ventilation windows 1-1 facing the inside of the cabinet, and a dust screen plate 3 and a filter sponge 4 are also fixed between the ventilation windows 1-1 and the protective cover plate 2. The side panel body 1 is formed by bending sheet metal material, and a ventilation window 1-1 is provided on the front side, which is a louver opening for ventilation; energy storage welding nails 1-2 are provided around the ventilation window 1-1, and the position and size match the fixing holes 2-1 on the protective cover plate 2, so that the protective cover plate 2 is fixed on the side panel body 1 and can completely cover the ventilation window 1-1. The protective cover plate 2 is formed by bending sheet metal material, and fixing holes 2-1 are provided on both sides, which cooperate with the energy storage welding nails 1-2 on the front of the side plate body 1 to fix the protective cover plate 2 on the side plate; the front is provided with a reverse louver air outlet 2-2, which not only increases the ventilation channel, but also prevents the long-term accumulated water vapor in the filter sponge 4 from condensing and dripping into the distribution box. The dustproof mesh plate 3 is processed by a metal mesh plate, and the front is evenly distributed with heat dissipation circular holes 3-1, whose diameter is related to the dustproof level, which is used to ensure ventilation and prevent foreign objects from invading the distribution equipment; the front is provided with a mesh plate fixing hole 3-2, whose size matches the energy storage welding nails 1-2 on the front of the side plate 1, which is used to fix the dustproof mesh plate 3. The filter sponge 4 is cut from the filter sponge, and its size matches the protective cover plate 2, and is pasted on the back of the reverse louver air outlet 2-2. Because the filter sponge has a porosity of up to 97%, it has excellent air permeability, can play the role of dustproof, ventilation, and splashing, and further improve the protection level of the distribution equipment.

[0018] In addition to the above embodiments, the present invention may also have other implementations. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present invention.
