Description

Technical Field

[0001] This utility model relates to the field of substation technology, and in particular to a fully underground prefabricated intelligent green substation. Background Technology

[0002] Prefabricated substations, also known as box-type substations or prefabricated substations, are factory-prefabricated, compact indoor or outdoor power distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution devices according to a specific wiring scheme. In urban centers, where land resources are extremely valuable, prefabricated substations need to be buried underground to address the problem of limited land resources.

[0003] Currently, existing prefabricated substations mainly rely on natural air convection and radiator cooling. However, their cooling effect is limited in high-temperature environments or when equipment is operating under high load. When faced with high-temperature environments or when equipment is operating under high load, their cooling effect is difficult to meet actual needs. Furthermore, because these prefabricated substations are installed underground, the underground environment is relatively closed and has poor air circulation, which further exacerbates the difficulty of heat dissipation and ventilation. If the internal equipment operates under high temperature conditions for a long time, it will greatly increase the risk of equipment failure. Therefore, this application provides a fully underground prefabricated intelligent green substation to meet the requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fully buried prefabricated intelligent green substation to solve the problem that existing prefabricated substations mainly rely on natural air convection and radiator heat dissipation, and that the heat dissipation and ventilation are poor because the prefabricated substations are buried underground.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0006] A fully buried prefabricated intelligent green substation includes: an outer shell; a heat dissipation assembly disposed below the outer shell; a sensor disposed inside the outer shell; two auxiliary ventilation pipes disposed symmetrically on the top of the outer shell; a ventilation assembly disposed above the outer shell; a delivery pipe, one end of which is connected to the center of the top of the outer shell, and the other end of which is connected to the ventilation assembly; an acceleration assembly disposed at the top of the inner cavity of the outer shell and connected to the delivery pipe; and an exhaust assembly disposed inside the outer shell for exhausting or intake air into the outer shell.

[0007] The heat dissipation assembly includes: a soil heat exchanger disposed below the housing and electrically connected to the sensor; two connecting pipes, one end of which is connected to the soil heat exchanger; a heat dissipation pipe disposed on the inner wall of the housing; and the other end of the connecting pipe passing through the housing and connected to the heat dissipation pipe.

[0008] The heat dissipation pipe is curved, and a phase change material is disposed inside the heat dissipation pipe.

[0009] The acceleration component includes: a mounting frame disposed inside the housing, one end of which is connected to the delivery pipe; a fan disposed on the mounting frame and electrically connected to the sensor; the exhaust component includes: a channel pipe disposed inside the housing, one end of which is connected to the other end of the mounting frame.

[0010] It also includes three entry and exit frames, which are respectively connected and installed on the channel tube, and are distributed in the upper, middle and lower positions.

[0011] The ventilation assembly includes an inlet / outlet ring block, which is connected to the top of the delivery pipe.

[0012] It also includes: a blocking frame, which is connected and disposed at the center of the inlet and outlet ring block for gas to enter or exit; and a drainage trough, which is disposed inside the inlet and outlet ring block, and the inner cavity of the drainage trough concentrically surrounds the blocking frame.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects.

[0014] In the above scheme, by setting up heat dissipation components, the relatively stable temperature of the underground soil can be effectively used to absorb the heat generated by the equipment inside the substation. The soil has a large heat capacity and can continuously provide a cold source for heat dissipation. At the same time, in conjunction with fans, the heat inside the casing is quickly dissipated, thereby improving the heat dissipation effect.

[0015] By incorporating three entry and exit frames arranged at the top, middle, and bottom, the system can more precisely regulate heat dissipation based on temperature variations in different height areas within the enclosure. This enables tiered and precise temperature control within the substation, ensuring that equipment in each area operates in a suitable temperature environment. Attached Figure Description

Detailed Implementation

[0024] The following is a detailed description of a fully buried prefabricated intelligent green substation provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0025] like Figure 1 - Figure 5 As shown, an embodiment of this utility model provides a fully buried prefabricated intelligent green substation, including: a shell 1; a heat dissipation assembly 5, disposed below the shell 1; a sensor 8, disposed inside the shell 1; two auxiliary ventilation pipes 2, disposed symmetrically on the top of the shell 1; a ventilation assembly 3, disposed above the shell 1; a delivery pipe 4, one end connected to the center of the top of the shell 1, and the other end connected to the ventilation assembly 3; an acceleration assembly 6, disposed at the top of the inner cavity of the shell 1 and connected to the delivery pipe 4; and an exhaust assembly 7, disposed inside the shell 1, used for exhausting or intake air into the shell 1.

[0026] The heat dissipation assembly 5 includes: a soil heat exchanger 51, which is disposed below the housing 1 and electrically connected to the sensor 8; two connecting pipes 52, one end of which is connected to the soil heat exchanger 51; a heat dissipation pipe 53, which is disposed on the inner wall of the housing 1; and the other end of the connecting pipe 52 passes through the housing 1 and is connected to the heat dissipation pipe 53.

[0027] The heat dissipation pipe 53 is curved, and a phase change material is installed inside it. By making the heat dissipation pipe 53 curved, the contact area between it and the air inside the outer casing 1 is effectively increased. Compared to a straight pipe, the curved shape allows the heat dissipation pipe 53 to extend a longer length within a limited space. According to the principle of heat exchange, the efficiency of heat exchange is proportional to the contact area. Increasing the contact area allows the heat dissipation pipe 53 to better absorb heat from the surrounding hot air. Simultaneously, the curved shape lengthens the path of air flowing through the heat dissipation pipe 53, increasing the time the air stays around it. By incorporating the phase change material, it can buffer the temperature rise when the equipment is operating under high load or when the external ambient temperature is high, causing a rapid increase in the substation's internal temperature. For example, if the equipment generates a large amount of heat in a short time, the phase change material can absorb this excess heat, preventing the temperature inside the outer casing 1 from becoming too high and maintaining the substation's internal temperature within a relatively stable range, thus avoiding equipment damage due to overheating. Furthermore, when the equipment's operating power decreases or the external ambient temperature drops, the phase change material releases the stored heat, helping to maintain the temperature balance inside the substation and reducing the adverse effects of temperature fluctuations on the equipment.

[0028] The acceleration component 6 includes: a mounting frame 61, which is disposed inside the housing 1 and has one end connected to the delivery pipe 4; a fan 62, which is disposed on the mounting frame 61 and electrically connected to the sensor 8; and an exhaust component 7 including: a channel pipe 71, which is disposed inside the housing 1 and has one end connected to the other end of the mounting frame 61.

[0029] It also includes three inlet / outlet frames 72, which are respectively connected to and installed on the channel pipe 71, distributed in an upper, middle and lower position. Three solenoid valves are installed on the channel pipe 71 to control the opening or closing of the three inlet / outlet frames 72. When the equipment is running under high load, the bottom equipment often accumulates more heat due to its proximity to the ground and relatively slow heat conduction. At this time, the exhaust volume of the lower inlet / outlet frame 72 is increased to quickly expel the hot air from the bottom. When the top accumulates more heat due to rising heat, the top inlet / outlet frame 72 can be opened to enhance the heat dissipation of the top.

[0030] The ventilation assembly 3 includes an inlet / outlet ring block 31, which is connected to the top of the delivery pipe 4. By setting the inlet / outlet ring block 31, which is disc-shaped, air can enter or exit relatively evenly from multiple directions. A filter screen or rainproof louver is set at the inlet to block external impurities and prevent them from entering the housing 1.

[0031] It also includes: a blocking frame 33, which is connected and disposed at the center of the inlet / outlet ring block 31 for gas to enter or exit; and a drainage trough 32, which is disposed inside the inlet / outlet ring block 31, with the inner cavity of the drainage trough 32 concentrically enclosing the blocking frame 33. By setting the drainage trough 32, which has several discharge holes, rainwater inside the inlet / outlet ring block 31 can be discharged. At the same time, a micro-membrane is provided on the blocking frame 33, which only allows air to enter and does not cause excessive obstruction to the normal air circulation.

[0032] The technical solution provided by this utility model involves the following steps: When the sensor 8 detects that the temperature inside the outer casing 1 is too high, the external controller activates the soil heat exchanger 51. The phase change material inside the heat dissipation pipe 53 absorbs heat and transfers it to the soil heat exchanger 51 through the connecting pipe 52. Heat exchange is carried out using the relatively stable low-temperature environment of the underground soil, dissipating heat into the soil. Simultaneously, the fan 62 operates, drawing hot air out of the outer casing 1 through the inlet / outlet frame 72 and expelling the hot air outward through the conveying pipe 4 and the inlet / outlet ring block 31, or drawing outside air into the outer casing 1, thereby dissipating heat. The bottom inlet / outlet frame 72 is opened by the solenoid valve, while the remaining two inlet / outlet frames 72 are closed, prioritizing heat dissipation at the bottom of the outer casing 1. The middle inlet / outlet frame 72 is opened by the solenoid valve, while the remaining two inlet / outlet frames 72 are closed, prioritizing heat dissipation at the middle position of the outer casing 1. The top inlet / outlet frame 72 is opened by the solenoid valve, while the remaining two inlet / outlet frames 72 are closed, prioritizing heat dissipation at the top position of the outer casing 1.
