Problems solved by technology

[0002] The power distribution cabinet is often unavoidably attacked by water. If water drips vertically from the top of the power distribution cabinet or enters the inside of the power distribution cabinet from the shell gap where the water drips at an angle of 15 degrees, the components of the power distribution cabinet will be soaked in water, resulting in failure of electrical equipment. normal operation
[0003] In order to solve the above problems, the whole body of the power distribution cabinet is designed as a sealed structure in the prior art. Although the waterproof problem of the power distribution cabinet is solved to a certain extent, the heat dissipation problem of the power distribution cabinet is ignored.

Embodiment 1

[0030] figure 1 A schematic diagram showing an embodiment of the waterproof distribution cabinet provided by the present invention, as figure 1 As shown, the cabinet body of the power distribution cabinet 1 is provided with at least one cooling hole 11, figure 2 show figure 1 Partial enlarged view at A, please also refer to figure 1 and figure 2 The upper edge of the cooling hole 11 has a water-retaining edge 12 extending outward, and the water-retaining edge 12 has a downwardly curved arc surface. The water enters the cooling holes 11 , thereby preventing water from flowing into the power distribution cabinet 1 from the cooling holes 11 . At the same time, the cooling holes 11 themselves also function to dissipate heat inside the power distribution cabinet 1 .

[0031] exist figure 1 and figure 2 In the above, the shape of the cooling hole 11 is a long strip extending in the horizontal direction. In practice, the cooling hole can also be set in other shapes, such as...

Embodiment 2

[0036] Figure 7 A schematic diagram showing an embodiment of the first power distribution cabinet group provided by the present invention, as Figure 7 As shown, the distribution cabinet group 7 includes at least two distribution cabinets 71, in Figure 7 In particular, two power distribution cabinets are used as an example for illustration, and the present invention is not limited thereto.

[0037] A cable channel shared by at least one pair of adjacent power distribution cabinets is provided between the adjacent power distribution cabinets. In practice, there are many forms of such a cable channel. For example, a cable channel cabinet may be provided between the adjacent power distribution cabinets, and the cable channel cabinet forms a cable channel. by Figure 7 As an example, a shared cable passage cabinet 73 is provided between two power distribution cabinets 71 . The cabinet space of the cabinet 73 is defined by the power distribution cabinets 71 on both sides, the...

Embodiment 3

[0041] Figure 8 A schematic diagram showing another embodiment of the first distribution cabinet group provided by the present invention, as Figure 8 As shown, the difference between the distribution cabinet group 7' and the distribution cabinet group 7 in the first embodiment mainly lies in the optimal design of the location of the busbar room.

[0042] In a common power distribution cabinet, the busbar room is set near the top of the cabinet, and equipment such as circuit breakers are installed under the busbar room. The busbar needs to be led from the busbar room to the various devices below, which makes the use of The quantity is relatively large, and the cost of the busbar is relatively high in practice, so the cost of the entire power distribution cabinet is overestimated.

[0043] This embodiment is an optimization scheme proposed after considering the above problems. See Figure 8 , the power distribution cabinet group 7' includes at least two power distribution c...

Abstract

The invention provides a waterproof power distribution cabinet and a power distribution cabinet group, wherein at least one heat dissipating hole is formed in the cabinet body of the power distribution cabinet and a water stop barrier edge is formed on the upper edge of the heat dissipating hole. The waterproof power distribution cabinet is capable of preventing water from flowing in while guaranteeing the heat dissipation property.

Description

technical field [0001] The invention belongs to the technical field of power distribution cabinets, in particular to a waterproof power distribution cabinet and a power distribution cabinet group. Background technique [0002] The power distribution cabinet is often unavoidably attacked by water. If water drips vertically from the top of the power distribution cabinet or enters the inside of the power distribution cabinet from the shell gap where the water drips at an angle of 15 degrees, the components of the power distribution cabinet will be soaked in water, resulting in failure of electrical equipment. normal operation. [0003] In order to solve the above problems, the whole body of the power distribution cabinet is designed as a sealed structure in the prior art. Although the waterproof problem of the power distribution cabinet is solved to a certain extent, the heat dissipation problem of the power distribution cabinet is ignored. Contents of the invention [0004]...
