Description

Technical Field

[0001] This utility model relates to the field of outdoor prefabricated substation technology, and in particular to an energy-saving heat dissipation device for outdoor prefabricated substations. Background Technology

[0002] A prefabricated substation, also known as a box-type substation, is a compact set of power distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution devices. It integrates traditional power distribution equipment into a box-type enclosure, offering significant advantages and has been widely used in various commercial and residential fields.

[0003] Currently, most outdoor transformer substations in production and living areas are installed on the ground, with a foundation pit beneath them containing buried cables. The substations rely primarily on passive and active cooling through ventilation holes and fans on their outer casing. However, in practice, to prevent insects and rodents from entering, the ventilation holes are generally small, making effective natural ventilation difficult. Furthermore, the operation of the cooling fans is controlled by a thermostat inside the substation. If the thermostat's critical temperature is set too high, it will fail to meet the cooling requirements of the enclosure in time; conversely, if the critical temperature is set too low, it will significantly increase the substation's energy consumption. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides an energy-saving heat dissipation device for outdoor transformer substations. It can utilize the temperature difference between the long-term low-temperature gas in the foundation pit and the high-temperature gas inside the transformer substation to form an airflow, thereby achieving energy-saving heat dissipation by driving the first heat dissipation component to rotate without power. When the temperature inside the transformer substation rises to a certain value, a low-power drive device can be activated to accelerate the operation of the first heat dissipation component, thereby further improving the heat dissipation efficiency. It can serve as an auxiliary device for high-power heat dissipation components on transformer substations, achieving the goal of continuous low-energy heat dissipation when the temperature inside the transformer substation is relatively low.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

The driving device is connected to the first heat dissipation component and electrically connected to a temperature control device installed inside the box. The temperature control device can instruct the driving device to drive the first heat dissipation component to rotate for heat dissipation.

[0009] As a further explanation of the above technical solution:

[0010] In the above technical solution, a mesh plate is installed on the inner wall of the bottom end of the box, and the first channel is provided on the side opposite to the box.

[0024] like Figure 1-2 As shown, the outdoor transformer substation has an energy-saving heat dissipation device. The substation includes a housing 10 for housing various electronic components. The housing 10 is placed on the ground, and a foundation pit 20 is located below it. Through holes for gas and cables to pass through are formed on the side walls of the foundation pit 20.

[0025] A first channel 1 is provided between the box 10 and the foundation pit pool 20, and the low temperature gas in the foundation pit pool 20 can enter the box 10 through the first channel 1.

[0026] The upper end of the housing 10 is provided with a second channel 2 that penetrates the housing 10. The second channel 2 is provided with a first heat dissipation component 30 and a drive device 40. The high-temperature airflow inside the housing 10 can be discharged to the outside of the housing 10 through the second channel 2 and push the first heat dissipation component 30 to rotate for heat dissipation. The drive device 40 is connected to the first heat dissipation component 30 by transmission and is electrically connected to a temperature control device installed inside the housing 10. The temperature control device can instruct the drive device 40 to drive the first heat dissipation component 30 to rotate for heat dissipation.

[0027] Furthermore, a mesh plate 3 is installed on the inner wall of the bottom end of the box 10, and a first channel 1 is provided on the side opposite to the box 10.

[0028] Furthermore, a heat dissipation box 50 is provided on the second channel 2. The heat dissipation box 50 is located on the outer wall of the upper end of the box body 10 and is connected to the interior of the box body 10. A drive device 40 is provided on it, and the first heat dissipation component 30 is located on the inner and / or outer side of the heat dissipation box 50.

[0029] In this embodiment, the drive device 40 is a motor, and the first heat dissipation component 30 includes a plurality of heat dissipation fins 4 that are connected to the motor shaft and surround it in the circumferential direction. Each heat dissipation fin 4 is a turbine blade 4a or fan blade 4b located on the outer side of the upper end of the heat dissipation box 50. A plurality of eaves heat dissipation holes 5 are provided on the side wall of the heat dissipation box 50.

[0030] like Figure 2 As shown, the working process of the energy-saving heat dissipation device in this utility model is as follows: When the substation is working, the temperature inside the box 10 will gradually rise. The relatively low-temperature gas in the underground pit pool 20 flows to the box 10 through the first channel 1 and enters the interior of the box 10 through the mesh plate 2. The high-temperature gas inside the box 10 is discharged from the box 10 and forms an airflow in the second channel 2, which drives the first heat dissipation component 30 to rotate, thus achieving energy-saving heat dissipation without power. When the airflow is too small to drive the first heat dissipation component 30 to rotate or when continuous operation causes the temperature inside the box 10 to rise to the set temperature, the temperature control device 40 inside the box 10 commands the first heat dissipation component 30 to rotate to accelerate heat dissipation. In this embodiment, the drive device 40 is a small motor with a power of 8W. It works in conjunction with the low-temperature gas in the pit pool 20 to automatically or actively discharge the gas inside the box 10 when the temperature inside the box 10 is not too high, resulting in low energy consumption.

[0031] like Figure 3-4 As shown, in application, turbine blades 4a or fan blades 4b or other heat sinks 4 can be applied to the first heat dissipation component 30 in combination with the actual outdoor wind conditions, so as to better utilize the external natural regulation to accelerate the rotation of the first heat dissipation component 30, further accelerate the airflow speed inside the box 10, and improve the effect of energy-saving heat dissipation without power.

[0032] This utility model energy-saving heat dissipation device sets up a first channel 1 that connects to the foundation pit pool 20 and the box body 10, and a second channel 2 that passes through the box body 10 and connects to the outside. A first heat dissipation component 30 and a driving device 40 are set on the second channel 2. The airflow is formed by the temperature difference between the long-term low temperature gas in the foundation pit pool and the high temperature gas in the box body 10, so as to realize the purpose of energy-saving heat dissipation by driving the first heat dissipation component to rotate without power. When the temperature inside the box body 10 rises to a certain value, the low-power driving device is activated to drive the first heat dissipation component 30 to accelerate its operation, so as to further improve the heat dissipation efficiency. It can be used as an auxiliary device for high-power heat dissipation components on the transformer box, so as to achieve the purpose of continuous low-energy heat dissipation when the temperature inside the box body 10 is relatively low.

[0033] Furthermore, a second heat dissipation component 60 is provided on the side wall of the housing 10. The second heat dissipation component 60 includes one or more heat dissipation fans 6 and ventilation slots 7 distributed on several side walls of the housing 10. The ventilation slots 7 include one or more of the following: eaves slots, louver slots, or heat dissipation holes. Each heat dissipation fan 6 is electrically connected to a temperature control device.

[0034] When the substation is operating continuously or when the temperature inside the enclosure 10 is abnormal, the temperature control device will instruct the relatively powerful cooling fan 6 to work and participate in heat dissipation, thereby accelerating the airflow inside the enclosure 10 to achieve accelerated heat dissipation and ensure that the temperature inside the enclosure 10 remains normal.

[0035] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
