Description

Technical Field

[0001] The present invention relates to the technical field of ring main units, and specifically to a sound absorption and noise reduction protection device based on outdoor ring main units. Background Art

[0002] A ring main unit is a set of power transmission and distribution electrical equipment (high-voltage switchgear) installed in a metal or non-metal insulated cabinet or made into a prefabricated sectionalized ring main power supply unit. Its core part uses a load switch and a fuse, and it is widely used in distribution substations and box-type substations in load centers such as urban residential areas, high-rise buildings, large public buildings, and industrial enterprises.

[0003] Existing ring main units are widely used and have the advantages of simple structure, small volume, low price, improved power supply parameters and performance, and power supply safety. However, they generally do not have a sound absorption and noise reduction structure. When the internal equipment of the ring main unit operates, it will generate noise, causing environmental pollution. However, directly adding sound insulation cotton will reduce the heat dissipation effect, resulting in the accumulation of heat inside the ring main unit and making it difficult to dissipate, so that the internal components will have a reduced service life due to high temperature.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

A box door 3 is hinged on the front side of the box body 2. A top plate 4 is fixed on the top of the box body 2. Rainproof and exhaust seats 5 are fixed on both the left and right sides of the box body 2. A dust-proof net 6 is assembled on the rainproof and exhaust seat 5. The provided dust-proof net 6 plays a role in blocking dust. The box body 2 includes an outer shell 7. The outer shell 7 is fixed between the base 1 and the top plate 4. A sound-insulating frame 8 located inside the outer shell 7 is fixed between the base 1 and the top plate 4. An inner shell 9 located inside the sound-insulating frame 8 is fixed between the base 1 and the top plate 4. A heat-conducting shell 10 located inside the inner shell 9 is fixed between the base 1 and the top plate 4. The provided box body 2 is composed of the outer shell 7, the sound-insulating frame 8, the inner shell 9 and the heat-conducting shell 10, and there is an exhaust gap between every two of them, which is convenient for air circulation and heat dissipation. The outer shell 7 and the inner shell 9 play a role in improving the strength of the box body 2. The components assembled inside the sound-insulating frame 8 are used for noise reduction and absorption to reduce noise emission. The heat-conducting shell 10 can absorb the heat generated by the operation of the components in the box body 2 and conduct the heat for dissipation. Heat dissipation covers 18 are fixed on both the left and right sides inside the heat-conducting shell 10. A fixing plate 19 is fixed on one side of the heat dissipation cover 18. A fan group 20 is assembled inside the fixing plate 19. A heat-conducting pipe 21 is fixed inside the heat-conducting shell 10. The number of the heat-conducting pipes 21 is two, and there is one on each of the left and right sides of the heat-conducting shell 10. The heat-conducting pipe 21 extends into the heat dissipation cover 18. The heat dissipation cover 18 corresponds to the position of the secondary exhaust hole 23.

[0030] A grille plate 13 is fixed inside the sound-insulating frame 8 of this embodiment. Sound-absorbing cotton 14 is filled inside the grille plate 13. The grille plate 13 is a honeycomb grille plate. The honeycomb grille plate provided inside the sound-insulating frame 8 makes the structure compact and has good strength. The sound-absorbing cotton 14 filled in the grille plate 13 is in the grid, and each piece of sound-absorbing cotton 14 is assembled tightly for sound absorption and noise reduction.

[0031] In the middle positions of the left and right sides of the sound insulation frame 8 in this embodiment, main exhaust air frames 15 are assembled. In the upper and lower positions of the left and right sides of the inner shell 9, auxiliary exhaust air frames 17 are assembled. An exhaust air channel shell 16 is assembled between the main exhaust air frame 15 and the auxiliary exhaust air frame 17. The main exhaust air frame 15 and the auxiliary exhaust air frame 17 are connected through the exhaust air channel shell 16 to form a complete exhaust air and heat dissipation channel, facilitating the discharge of heat in the box body 2.

[0032] The working principle of the above embodiment is as follows:

[0033] (1) The box body 2 is composed of an outer shell 7, a sound insulation frame 8, an inner shell 9, and a heat conduction shell 10. There is an exhaust air gap between every two of the four, facilitating air circulation and heat dissipation. After the fan group 20 is started, exhaust air operation is carried out. The heat conduction pipe 21 and the heat dissipation cover 18 absorb and conduct the heat in the box body 2. When exhausting air, the air circulation carries the heat and enters the exhaust air channel shell 16 through the auxiliary exhaust air frame 17, and then is discharged from the main exhaust air frame 15 and the main exhaust air holes 22. The dust-proof net 6 assembled on the rain-proof exhaust air seat 5 facilitates air circulation and blocks dust.

[0034] (2) The noise generated by the operation of the equipment in the box body 2 reaches the sound insulation frame 8 after being slightly weakened by the heat conduction shell 10 and the inner shell 9. The sound insulation cotton 14 filled in the grille plate 13 of the sound insulation frame 8 absorbs the noise for noise reduction treatment.
