Description

Technical Field

[0001] The present invention relates to the technical field of transformer substations, and in particular to an intelligent box-type transformer substation. Background Art

[0002] A box-type substation is a device that organically combines the functions of transformer step-down and low-voltage power distribution, and installs it in a steel structure box with moisture-proof, fire-proof and fully enclosed functions. It is particularly suitable for urban network construction and transformation. In order to facilitate heat dissipation in the box, an air inlet is generally opened at the top of the box, and a canopy is installed on the top of the box to prevent rainwater from entering the box and causing damage to the transformer.

[0003] It is difficult for the existing box to completely shield the air inlet from rain. When the wind and rain outside are strong, rainwater may flow into the box through the air inlet along the surface of the box and cause damage to the transformer. At the same time, dust from the outside will also enter the box through the air inlet, causing the dust to adhere to the surface of the transformer, affecting the heat dissipation and life of the transformer. Summary of the Invention

[0004] In view of the above problems existing in the existing box-type substation, the present invention aims to provide an intelligent box-type substation.

[0005] The specific technical solutions are as follows:

[0006] An intelligent box-type substation comprises: a box body, a component is provided in the middle of the box body, a heat dissipation fan is provided on the top of the box body, at least one air inlet channel is provided on the top of the box body, a filter is provided in the air inlet channel for filtering dust, the air inlet channel comprises a water collection section, a connecting section and a filtering section connected in sequence, the water collection section is vertically distributed, and the top of the water collection section is connected to the outside of the box body, one end of the connecting section is connected to the side of the water collection section, and the other end is connected to one end of the filtering section, and the other end of the filtering section is connected to the box body, wherein the filter is provided in the filtering section.

[0007] As a further improvement and optimization of this solution, the filter screen is arranged at the connection between the filter section and the communication section.

[0008] As a further improvement and optimization of this solution, the filter screen is a cylindrical structure, and an inlet is provided on the side of the filter screen, and the inlet is connected to the air outlet end of the connecting section.

[0009] As a further improvement and optimization of this solution, a mounting groove matching the filter screen is provided on the side of the box body, and the filter screen is coaxially arranged in the mounting groove and forms a sealed sliding fit with the inner wall of the mounting groove.

[0010] As a further improvement and optimization of this solution, a sealing groove is provided on the filter screen, a sealing ring is provided in the sealing groove, and the sealing ring is sealed and matched with the notch of the installation groove.

[0011] As a further improvement and optimization of this solution, the outer wall of the filter screen also has a guide slide bar, the groove wall of the installation groove is provided with a guide slide groove, and the guide slide bar and the guide slide groove form a sliding fit along the axial direction of the installation groove.

[0012] As a further improvement and optimization of this solution, a handle is provided at the outer end of the filter.

[0013] As a further improvement and optimization of this solution, both sides of the bottom of the water collecting section are provided with water guide holes communicating with the outside of the box.

[0014] As a further improvement and optimization of this solution, heat dissipation openings are provided on both sides of the bottom of the box body, and each of the heat dissipation openings is provided with a baffle arranged in an inclined manner.

[0015] As a further improvement and optimization of this solution, a rain shelter is further provided on the top of the box body, and two air inlet channels are provided, and are respectively located on both sides of the rain shelter.

[0016] Compared with the prior art, the above technical solution has the following positive effects:

[0017] (1) In the present invention, when rainwater enters from the air inlet channel, the rainwater flows into the bottom of the water collection section under the action of its own gravity for centralized collection, thereby preventing rainwater from entering the box and causing damage to the working components. At the same time, when the heat dissipation fan draws cold air into the box from the air inlet channel, the cold air enters the interior of the box from the water collection section, the connecting section, and the filtering section in turn. The dust in the cold air is intercepted and filtered by the filter net, thereby preventing external dust from being drawn into the box and adhering to the components, thereby affecting the heat dissipation of the components and further improving the protection of the components.

[0018] (2) The filter screen of the present invention is a cylindrical structure, and an inlet is provided on the side of the filter screen, which is connected to the air outlet end of the connecting section. When dust enters the filter screen from the inlet, the dust will be intercepted by the filter screen and collected in the filter screen.

[0019] (3) In order to facilitate the disassembly and assembly of the filter and the removal of dust inside the filter, the side of the box is provided with a mounting groove that matches the filter. The filter is coaxially arranged in the mounting groove and forms a sealed sliding fit with the inner wall of the mounting groove. By adopting the sliding assembly of the filter and the mounting groove, the disassembly and assembly of the filter and the cleaning of the internal dust are greatly facilitated, and the excessive accumulation of dust is avoided to block the filter and affect the air intake inside the box.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

A filter screen 2 is provided in the air inlet channel 11 for filtering dust. The air inlet channel 11 comprises a water collection section 111, a connecting section 112 and a filtering section 113 connected in sequence. The water collection section 111 is vertically distributed, and the top of the water collection section 111 is connected to the outside of the box body 1, one end of the connecting section 112 is connected to the side of the water collection section, and the other end is connected to one end of the filtering section 113, and the other end of the filtering section 113 is connected to the box body 1, wherein the filter screen 2 is provided in the filtering section 113.

[0027] In this embodiment, when rainwater enters from the air inlet channel 11, the rainwater flows into the bottom of the water collecting section 111 under the action of its own gravity for centralized collection, thereby preventing rainwater from entering the box body 1 and causing damage to the working components 5. At the same time, when the heat dissipation fan 6 draws cold air into the box body 1 from the air inlet channel 11, the cold air enters the interior of the box body 1 from the water collecting section 111, the connecting section 112, and the filtering section 113 in sequence. The dust in the cold air is intercepted and filtered by the filter 2, thereby preventing external dust from being drawn into the box body 1 and adhering to the components 5, thereby affecting the heat dissipation of the components 5 and further improving the protection of the components 5.

[0028] Preferably, in this embodiment, the connecting section 112 is arranged to be inclined upward, so as to further prevent rainwater in the air inlet channel 11 from entering the filtering section 113 .

[0029] Preferably, in order to further prevent rainwater from entering the box body 1 through the air inlet channel 11, the filter section 113 is a U-shaped channel structure.

[0030] Furthermore, as a preferred embodiment, the filter screen 2 is provided at the connection between the filtering section 113 and the communicating section 112 .

[0031] Furthermore, as a preferred embodiment, the filter 2 is a cylindrical structure, and an inlet 21 is provided on the side of the filter 2, and the inlet 21 is connected to the air outlet end of the connecting section 112.
