Embodiment 1

[0032] see Figure 1 to Figure 4 , a ventilation device is arranged on the top of the transformer cabinet, and the ventilation device includes a cabinet top plate 1, which is connected to the transformer cabinet by welding; A first protective plate 31 and a second protective plate 32 are arranged successively around the wind filter 2, the first protective plate 31 is positioned at the inner side of the second protective plate 32, and the first protective plate 31 and the second protective plate 32 jointly form a A first protective groove 3 with a cross-sectional shape of "U"; a top cover plate support 5 is also arranged on the cabinet top plate 1; a top cover plate 6 is fixed above the cabinet top plate 1 through the top cover plate support 5 , the fixing method can be the fixing of nuts and bolts, and can also be fixed structures such as welding and riveting; the side of the top cover plate 6 facing the top plate of the cabinet is provided with a third protective plate 41 and...

Embodiment 2

[0039] As a modification of Embodiment 1, see Figure 6 and Figure 7, the heights of the first protective plate 31, the second protective plate 32, the third-party protective plate 41 and the fourth protective plate 42 at this time are consistent, and the height of the top cover plate support 5 is the height of the first protective plate 31. 1.4 times, the bottom of the second protective plate 32 is uniformly provided with drainage holes 8 .

[0040] In this example, see Figure 6 , the distance between the first protective plate 31 and the top cover plate 6 is 0.4 times the first protective plate 31, while in Embodiment 1 the distance between the first protective plate 31 and the top cover plate 6 is 0.2 times the first The protective plate 31, therefore, the heat dissipation channel in this embodiment is larger than the heat dissipation channel in Embodiment 1, and the heat dissipation effect is better.

[0041] For waterproofing, see Figure 9 , only when water drops i...

Abstract

The invention provides a ventilation device of power distribution equipment. The ventilation device comprises a cabinet top plate and an air outlet filter net arranged on the cabinet top plate. A first protective plate and a second protective plate are sequentially arranged on the periphery of the air outlet filter net, the first protective plate is located on the inner side of the second protective plate, and a first protective groove with the U-shaped cross section is defined by the first protective plate and the second protective plate jointly. A top cover plate supporting piece is further arranged on the cabinet top plate, a top cover plate is fixed above the cabinet top plate through the top cover plate supporting piece, a third protective plate and a fourth protective plate are arranged on the side, facing the cabinet top plate, of the top cover plate, the third protective plate is located on the inner side of the fourth protective plate, and a second protective groove with the U-shaped cross section is defined by the third protective plate and the fourth protective plate jointly. The first protective groove and the second protective groove are vertically overlapped in an oppositely-intersected mode. By means of the ventilation device of the double-U-groove structure, the radiating ventilation area is increased, water and dust are prevented from entering the power distribution equipment, and the high radiating grade and the high IP protective grade are guaranteed at the same time.

Description

technical field [0001] The invention belongs to the technical field of power distribution cabinets, and relates to a low-voltage complete switchgear, in particular to a ventilation device for power distribution equipment. Background technique [0002] With the rapid development of China's economy and the acceleration of urbanization, more than 20 cities in my country are currently carrying out or embarking on the construction of rail transit, and rail transit is increasingly becoming the main means of transportation for citizens' work and life. Urban rail transit is mostly located underground, and tunnels need to be excavated during construction. Shields used for tunnel excavation are generally equipped with more mobile power distribution equipment, including 10KV high-voltage switchgear, power transformers and 0.4KV low-voltage power distribution equipment. These equipments have been operating in the harsh environment of high humidity, dripping, leaking, splashing and dusty...
