Description

Technical Field

[0001] The present invention relates to the technical field of substations, and in particular to a substation. Background Art

[0002] Substations are highly airtight, and high-voltage equipment in substations will emit a lot of heat during operation. If the heat cannot be discharged in time, the excessive temperature will not only affect the operation of the high-voltage equipment, but also accelerate the aging of component insulation and may even cause a fire. Traditional cooling measures for substations mainly rely on setting vents on the walls of the substation for ventilation and heat dissipation. The ventilation methods include natural air intake, mechanical air intake, natural exhaust and mechanical exhaust.

[0003] However, when the vents are improperly arranged, it is easy to cause air flow short circuit, often resulting in poor heat dissipation in the substation and difficulty in discharging the residual heat inside the substation, resulting in low ventilation and heat dissipation efficiency in the substation.

[0010] Furthermore, each guide component includes at least two guide plates, a flow gap is provided between any two adjacent guide plates, each guide plate is detachably connected to the through slot, and the extension directions of each guide plate are arranged in parallel.

[0011] Furthermore, each guide component also includes a connecting rod, the extension direction of the connecting rod is parallel to the extension direction of the side wall where the through slot corresponding to the guide component is located, and a plurality of guide plates are arranged on the connecting rod at intervals along the extension direction of the connecting rod, and the connecting rod is detachably connected to the corresponding through slot.

[0026] Please refer to Figures 1 to 4 The present invention provides a substation, comprising: a shell 10, the shell 10 is used to enclose a cavity 11 for accommodating a device to be cooled 1, the shell 10 has four side walls 12 arranged in sequence along the circumferential direction of the device to be cooled 1, and a through groove 14 is arranged at the bottom of each side wall 12, the through groove 14 penetrates the inner cavity wall of the cavity 11 to form a first air outlet 13, and the through groove 14 penetrates the outer cavity wall of the cavity 11 to form a first air inlet 16; wherein the first air inlet 16 is connected with the first air outlet 13, and the first air outlet 13 is connected with the cavity 11, and the air outlet directions of the first air outlets 13 on any two adjacent side walls 12 can be arranged to intersect, and the air outlet directions of the four first air outlets 13 are distributed clockwise or counterclockwise around the device to be cooled 1.

[0027] The substation of the present invention comprises a shell 10, the shell 10 is used to enclose a cavity 11 for accommodating a heat dissipation device 1, the shell 10 has four side walls 12 arranged in sequence along the circumferential direction of the heat dissipation device 1, and the bottom of each side wall 12 is provided with a through groove 14, the through groove 14 penetrates the inner cavity wall of the cavity 11 to form a first air outlet 13, and the through groove 14 penetrates the outer cavity wall of the cavity 11 to form a first air inlet 16. Since the air outlet directions of the first air outlets 13 on any two adjacent side walls 12 can be arranged to intersect, the air outlet directions of the four first air outlets 13 are arranged to intersect. The wind direction is distributed clockwise or counterclockwise around the device to be cooled 1, so that the airflow from the outside flows through the first air inlet 16 and the first air outlet 13 in sequence and then enters the cavity 11. The airflow directions of the four first air outlets 13 are distributed in the same clockwise direction, forming a vortex at the bottom of the device to be cooled 1. The hot air in the cavity 11 is swirled and discharged upward under the drive of the vortex, and finally takes away the heat in the cavity 11, thereby enhancing the heat dissipation effect of the substation and improving the heat dissipation efficiency of the substation, thereby solving the problem of low ventilation and heat dissipation efficiency of the substation in the prior art.

[0028] In this embodiment, the air outlet directions of the first air outlets 13 on any two adjacent side walls 12 are arranged perpendicular to each other.

[0029] Specifically, such a configuration further ensures that the airflow flowing in from the four first air outlets 13 can form a vortex at the bottom of the device to be cooled 1, thereby ensuring the cooling efficiency of the substation.

[0030] In this embodiment, the value range of the angle θ1 between the extension direction of each side wall 12 and the air supply direction of the first air outlet 13 thereon is: 30°≤θ1≤60°.

[0031] Specifically, since any two adjacent side walls are arranged perpendicularly, the angle between the extension direction of each side wall 12 and the air supply direction of the first air outlet 13 thereon is the same, and is θ1. When 30°≤θ1≤60°, it can be ensured that the air outlet directions of the first air outlet 13 on any two adjacent side walls 12 can be arranged to intersect, and the air outlet directions of the four first air outlets 13 are distributed clockwise or counterclockwise around the heat dissipation device 1.

[0032] In this embodiment, the angle θ1 between the extension direction of each side wall 12 and the air supply direction of the first air outlet 13 thereon is equal to 45°.

[0033] Specifically, such an arrangement can ensure that the airflow flowing in from the four first air outlets 13 is blown onto the heat dissipation device 1 in a relatively concentrated manner, thereby enhancing the heat dissipation efficiency of the substation.

[0034] In this embodiment, the substation also includes four guide components, and the four guide components are arranged in a one-to-one correspondence with the four through slots 14. Each guide component is arranged in the corresponding through slot 14, and each guide component has a flow gap 21. The two ends of the flow gap 21 are respectively connected to the first air outlet 13 and the first air inlet 16, so that the airflow flowing in from the first air inlet 16 flows through the flow gap 21 and enters the cavity 11 from the first air outlet 13; wherein, the extension direction of the flow gap 21 of the guide component in each through slot 14 is the air outlet direction of the first air outlet 13 of each through slot 14.

[0035] Specifically, the airflow in the through slot 14 is restricted from flowing out of the flow gap 21 to constrain the air outlet direction from the first air outlets 13, thereby ensuring that the airflow flowing in from the four first air outlets 13 can form a vortex at the bottom of the heat dissipation device 1.

[0036] In this embodiment, each guide component includes at least two guide pieces 20, and there is a flow gap 21 between any two adjacent guide pieces 20. Each guide piece 20 is detachably connected to the through slot 14, and the extension directions of each guide piece 20 are arranged in parallel.

[0037] Specifically, any two guide plates 20 are used to form a flow gap 21, so that the airflow in the through groove 14 can only flow out from the flow gap 21. At the same time, by controlling the extension direction of the guide plates 20, the extension direction of the flow gap 21 can be controlled, and then the flow direction of the airflow flowing out of the flow gap 21 can be controlled, that is, the air outlet direction of the first air outlet 13 can be controlled.

[0038] In this embodiment, each guide component also includes a connecting rod 23, and the extension direction of the connecting rod 23 is parallel to the extension direction of the side wall 12 where the through groove 14 corresponding to the guide component is located. A plurality of guide plates 20 are arranged on the connecting rod 23 at intervals along the extension direction of the connecting rod 23, and the connecting rod 23 is detachably connected to the corresponding through groove 14.

[0039] Specifically, the connecting rod 23 is used to connect the through slot 14 and the guide piece 20 to ensure that the guide piece 20 can guide the airflow flowing into the through slot 14; when the extension direction of the guide piece 20 needs to be changed, the connecting rod 23 can be removed and the guide piece 20 can be replaced.

[0040] In this embodiment, the substation also includes a filter element 30, which is arranged in the through groove 14. The filter element 30 includes a plurality of through holes 31 arranged at intervals, and the two ends of each through hole 31 are respectively connected to the first air inlet 16 and the flow gap 21, so that the filter element 30 can filter the airflow flowing into the first air inlet 16.

[0041] Specifically, the airflow flowing into the first air inlet 16 is filtered by the filter element 30 to prevent external dust and impurities from entering the through groove 14 through the first air inlet 16, causing the heat dissipation device 1 to be contaminated. It can also prevent the flow gap 21 from being blocked by impurities, resulting in a smaller air flow rate flowing into the first air outlet 13, affecting the heat dissipation effect of the substation.

[0042] In this embodiment, the substation further includes a plurality of fans, and the plurality of fans and the plurality of through slots 14 are arranged in one-to-one correspondence, and the second air outlet of each fan is arranged in communication with the first air inlet 16 of the corresponding through slot 14 .

[0043] Specifically, the fan is used to control the flow rate of the airflow flowing out of the corresponding through slot 14 from the first air outlet 13, thereby enhancing the heat dissipation effect of the airflow on the heat dissipation device 1.

[0044] In this embodiment, the shell 10 further includes a top wall 15 connected to the four side walls 12 . An exhaust port 151 is formed on the top wall 15 . The exhaust port 151 is communicated with the cavity 11 so that the air flow in the cavity 11 can be discharged through the exhaust port 151 .

[0045] Specifically, the exhaust port 151 is used to exhaust the hot air flow in the cavity 11. The airflow directions of the four first air outlets 13 are distributed in the same clockwise direction, forming a vortex at the bottom of the heat dissipation device 1. The hot air in the cavity 11 swirls upward into the exhaust port 151 driven by the vortex and then discharged, finally taking away the heat in the cavity 11.

[0046] Specifically, the substation of the present invention improves the heat dissipation effect of high-voltage equipment and effectively reduces the indoor temperature. Comparing the total heat transfer on the surface of the device to be radiated 1 in the prior art and the present invention, the results show that: the temperature on the surface of the device to be radiated 1 is reduced from 50°C to below 40°C, and the heat accumulation phenomenon above the device to be radiated 1 is significantly alleviated; the average temperature in the cavity 11 is reduced by 11%, and the maximum temperature at 0.3m above the device to be radiated 1 is reduced by 22%.

[0047] Specifically, the size of the first air outlet 13 of the present invention is 2m×1m, the air supply speed is 2.5m / s, the air supply temperature is 31°C, and the size of the exhaust port 151 is 2m×2m.

[0048] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0049] The substation of the present invention comprises a shell 10, the shell 10 is used to enclose a cavity 11 for accommodating a heat dissipation device 1, the shell 10 has four side walls 12 arranged in sequence along the circumferential direction of the heat dissipation device 1, and the bottom of each side wall 12 is provided with a through groove 14, the through groove 14 penetrates the inner cavity wall of the cavity 11 to form a first air outlet 13, and the through groove 14 penetrates the outer cavity wall of the cavity 11 to form a first air inlet 16. Since the air outlet directions of the first air outlets 13 on any two adjacent side walls 12 can be arranged to intersect, the air outlet directions of the four first air outlets 13 are arranged to intersect. The wind direction is distributed clockwise or counterclockwise around the device to be cooled 1, so that the airflow from the outside flows through the first air inlet 16 and the first air outlet 13 in sequence and then enters the cavity 11. The airflow directions of the four first air outlets 13 are distributed in the same clockwise direction, forming a vortex at the bottom of the device to be cooled 1. The hot air in the cavity 11 is swirled and discharged upward under the drive of the vortex, and finally takes away the heat in the cavity 11, thereby enhancing the heat dissipation effect of the substation and improving the heat dissipation efficiency of the substation, thereby solving the problem of low ventilation and heat dissipation efficiency of the substation in the prior art.
