Description

Technical Field

[0001] This invention relates to the field of prefabricated substation technology, specifically to a prefabricated substation with adaptive zoned precise ventilation and heat dissipation. Background Technology

[0002] Prefabricated substations integrate various electrical equipment, including transformers, high-voltage switchgear, low-voltage switchgear, and reactive power compensation devices. These devices generate significant heat during operation, with transformers being the primary heat source. Their iron and copper losses are converted into heat, leading to a significant increase in ambient temperature. Poor heat dissipation can cause the temperature rise of electrical equipment to exceed permissible limits, accelerating insulation aging, reducing equipment lifespan, and in severe cases, even causing equipment failure or fire. Therefore, ventilation and heat dissipation are crucial aspects of prefabricated substation design. Existing ventilation and heat dissipation solutions for prefabricated substations mainly include the following:

[0003] (1) Natural ventilation heat dissipation: Heat dissipation is achieved by using louvers or ventilation holes on the side walls of the enclosure and relying on the natural convection principle of rising hot air. This method is simple in structure and low in cost, but the heat dissipation efficiency is low. It is only suitable for occasions with low heat generation and is greatly affected by ambient temperature and wind speed.

[0004] (2) Forced ventilation cooling: Fixed axial flow fans or exhaust fans are installed inside the enclosure to expel hot air from the enclosure through mechanical forced ventilation. This method has high cooling efficiency, but it has the following shortcomings: First, all fans are usually started and stopped at the same time, and it is impossible to differentiate control according to the actual heat generation of equipment in each area. This results in insufficient heat generation in some areas and excessive heat generation in others, which affects equipment safety and causes energy waste. Second, the installation position and air outlet direction of the fans are fixed, making it impossible to accurately deliver air to specific heat-generating equipment, resulting in poor heat dissipation uniformity. Third, when the load of equipment in a certain area suddenly increases and the temperature rises sharply, relying solely on the fans in that area is often insufficient to meet the heat dissipation requirements, lacking the ability to coordinate heat dissipation between areas.

[0005] (3) Air conditioning cooling: Active cooling is achieved by installing air conditioning equipment inside the enclosure. This method has the best heat dissipation effect, but it has high energy consumption and cost, and the installation and maintenance of air conditioning equipment also increases the complexity of the box-type substation.

[0006] Therefore, it is necessary to provide a prefabricated substation with adaptive zoning and precise ventilation and heat dissipation to solve the above problems. Summary of the Invention

[0007] To address the above problems, the present invention provides the following technical solution: a prefabricated substation with adaptive zoned precise ventilation and heat dissipation, comprising:

[0011] Each of the temperature-controlled zones is equipped with electrical devices, and each of the electrical devices is equipped with a temperature sensor. The ventilation and heat dissipation components are selectively activated based on the detection signal from the temperature sensor.

[0012] Furthermore, as a preferred embodiment, the inner top of the enclosure is also provided with a top plate, and the top plate and the top of the enclosure form a ventilation space. Each temperature control zone is provided with at least two ventilation pipes, which are installed on the top plate and communicate with the ventilation space. Ventilation valves are also provided on the ventilation pipes.

[0013] Furthermore, as a preferred embodiment, when the cooling effect of the ventilation and heat dissipation components in a certain temperature control area is insufficient, the ventilation and heat dissipation components in the other temperature control areas supply air to the ventilation space through their respective corresponding ventilation pipes. The air is discharged from the ventilation space into the temperature control area through the ventilation pipe corresponding to the temperature control area with insufficient cooling effect, so as to achieve auxiliary cooling.

[0014] Furthermore, preferably, the ventilation and heat dissipation assembly includes:

[0015] The base is a cylindrical compartment structure;

[0016] A turntable is rotatably mounted on the base about the vertical central axis of the base;

[0017] A lifting assembly is mounted on the turntable and has a lifting end;

[0018] A steering component is disposed at the lifting end and has a steering end;

[0019] An air supply assembly is located at the directional control end.

[0020] Furthermore, as a preferred embodiment, the turntable has a through groove at its center, a gear ring is provided in the through groove, a servo motor is fixed in the base, and a gear that meshes with the gear ring is provided at the output end of the servo motor.

[0021] Furthermore, preferably, the orientation component includes:

[0022] A connecting seat is rotatably mounted on the lifting end and driven by a rotating motor; a deflection motor is provided on the connecting seat.

[0023] A deflection mount is fixed to the output end of the deflection motor;

[0024] A connecting shaft, serving as the directional adjustment end, is connected between the deflection seat and the air supply assembly;

[0025] The rotation center axis of the connecting seat is perpendicular to the vertical center axis of the base. The output end of the deflection motor can drive the deflection seat to deflect up and down, and the deflection center axis of the deflection seat is perpendicular to the rotation center axis of the connecting seat.

[0026] Furthermore, preferably, the air supply assembly includes:

[0027] The air supply chamber is fixed to the directional end and connected to an external air supply device via an external pipe.

[0028] The installation compartment is installed on one side of the air supply compartment;

[0029] The air supply duct is connected to the air supply chamber at one end via a flexible tube. The air supply duct is also rotatably connected to the installation chamber via a directional shaft and is driven by a micro motor.

[0030] A first valve body is provided at the connection between the air supply chamber and the flexible pipe.

[0031] Furthermore, as a preferred embodiment, a temperature gauge is embedded in the air supply chamber, an exhaust port is provided in the middle of the air supply chamber, and a second valve body is provided in the exhaust port;

[0032] A cooler is provided in the middle of the installation compartment. The side of the cooler is made of heat-conducting material. A slip ring is slidably sleeved on the side of the cooler. A flexible heat-insulating sleeve is connected between the slip ring and the bottom of the cooler. A spring is also connected between the slip ring and the bottom of the cooler.

[0033] The surface of the air supply pipe is provided with multiple through holes;

[0034] When the thermometer detects that the gas temperature is greater than a preset threshold, the first valve body is closed and the second valve body is opened.

[0035] Furthermore, as a preferred embodiment, the cooler is a semiconductor cooler or a phase change cooler. When the cooler is a phase change cooler, external airflow can be introduced through the exhaust port at night to cool the phase change cooler.

[0036] Compared with the prior art, the present invention provides a prefabricated substation with adaptive zoned precise ventilation and heat dissipation, which has the following beneficial effects:

[0037] In this invention, the enclosure is divided into multiple temperature-controlled zones by partitions. Each temperature-controlled zone is independently equipped with ventilation and heat dissipation components, which are selectively activated based on the detection signals of the temperature sensors built into the electrical equipment. Active heat dissipation is only performed on the areas where the temperature exceeds the standard, thus avoiding unnecessary energy consumption.

[0038] In this invention, a shared airflow channel is constructed between the temperature-controlled areas through the ventilation space between the top plate and the top of the box, and the ventilation pipes of each temperature-controlled area. When the heat dissipation demand of a certain temperature-controlled area suddenly increases, the ventilation and heat dissipation components of the other temperature-controlled areas can supply air to the ventilation space, which is then discharged into the target area through the ventilation pipe to achieve auxiliary cooling. This improves the overall heat dissipation redundancy without the need for additional heat dissipation equipment.

[0039] In this invention, the ventilation and heat dissipation component adopts a multi-layer modular structure consisting of a base, a turntable, a lifting component, a directional component, and an air supply component. By rotating the turntable around the vertical central axis, adjusting the height of the lifting component, and adjusting the deflection of the directional component, the air supply component achieves precise positioning with multiple degrees of freedom in three-dimensional space, which can accurately direct the airflow to the heat-generating equipment and significantly improve heat dissipation efficiency.

[0046] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.

[0047] Example: In this embodiment of the invention, please refer to... Figures 1-5 This provides a prefabricated substation with adaptive zoning and precise ventilation and heat dissipation, including:

[0048] Box 1, the bottom of which is provided with an exhaust plate 4 and the top of which is provided with a box top;

[0049] Multiple partitions 2 are fixed in the box 1 to divide the box 1 into multiple temperature control zones;

[0050] Multiple ventilation and heat dissipation components 3 are respectively set in the corresponding temperature control areas;

[0051] Each of the temperature control zones is equipped with electrical devices, and each of the electrical devices is equipped with a temperature sensor. The ventilation and heat dissipation assembly 3 is selectively activated based on the detection signal from the temperature sensor.

[0052] The temperature sensor is, for example, any one of a thermocouple temperature sensor, a thermistor temperature sensor, or an infrared temperature sensor. The ventilation and heat dissipation component 3 is selectively activated based on the detection signal of the temperature sensor. That is, when the temperature of electrical equipment in a certain temperature control area exceeds a preset temperature threshold, the ventilation and heat dissipation component 3 in that area automatically starts to dissipate heat. When the temperature drops back to a safe range, the ventilation and heat dissipation component 3 automatically shuts down. This achieves zoned adaptive heat dissipation, which only allocates heat dissipation resources to the temperature control area that needs cooling, avoiding ineffective heat dissipation in areas with normal temperatures and significantly reducing energy consumption.

[0053] In this embodiment, a top plate 6 is also provided on the inner top of the box 1. The top plate 6 and the top of the box form a ventilation space. Each temperature control zone is provided with at least two ventilation pipes 5. The ventilation pipes 5 are installed on the top plate 6 and communicate with the ventilation space. A ventilation valve is also provided on the ventilation pipe 5. The ventilation valve is, for example, any one of a solenoid valve or an electric butterfly valve.

[0054] In other words, the ventilation space between the top plate 6 and the top of the enclosure provides a shared airflow transfer channel for each temperature-controlled zone, and the ventilation pipes 5 and ventilation valves constitute a pipeline network connecting each temperature-controlled zone and the ventilation space. This structure provides the necessary infrastructure for subsequent cross-regional collaborative heat dissipation functions, enabling airflow allocation between different temperature-controlled zones through the ventilation space.

[0055] Furthermore, when the cooling effect of the ventilation and heat dissipation component 3 in a certain temperature control area is insufficient, the ventilation and heat dissipation components 3 in the other temperature control areas supply air to the ventilation space through their respective corresponding ventilation pipes 5. The air is discharged from the ventilation space into the temperature control area through the ventilation pipe 5 corresponding to the temperature control area with insufficient cooling effect, so as to achieve auxiliary cooling.

[0056] In other words, when the cooling effect of the ventilation and heat dissipation component 3 in a certain temperature control area is insufficient (for example, when the load of electrical equipment in the temperature control area suddenly increases or the ambient temperature rises sharply), the cross-regional collaborative heat dissipation mode is activated.

[0057] The specific working process is as follows: The ventilation and heat dissipation components 3 of the other temperature control areas supply air to the ventilation space through their respective ventilation pipes 5. At this time, in the temperature control area that needs to be cooled, the ventilation valve on the ventilation pipe 5 used to introduce airflow from the ventilation space remains open, and the air from the ventilation space is discharged into the temperature control area that needs to be cooled through the open ventilation pipe 5, providing additional cooling airflow to the area and achieving auxiliary cooling.

[0058] More specifically, in the cross-regional collaborative heat dissipation mode, the ventilation and heat dissipation components 3 of the other temperature control areas cooperate with their own rotation motors and deflection motors to align the air supply components 35 with the ventilation pipes 5 used to supply air to the ventilation space in that area, ensuring that the airflow enters the ventilation space efficiently through the ventilation pipes 5.

[0059] In this embodiment, the ventilation and heat dissipation component 3 includes:

[0060] The base 31 is a cylindrical compartment structure;

[0061] Turntable 32 is rotatably mounted on base 31 about the vertical central axis of base 31;

[0062] The lifting assembly 33 is disposed on the turntable 32 and has a lifting end;

[0063] The directional component 34 is disposed at the lifting end and has a directional end;

[0064] Air supply component 35 is disposed at the directional adjustment end.

[0065] The air supply component 35 is located at the directional adjustment end and is used to generate and output cooling airflow. The position and orientation of the air supply component 35 are jointly determined by the rotation angle of the turntable 32, the lifting height of the lifting component 33, and the deflection angle of the directional adjustment component 34, realizing the precise positioning of the air supply component 35 in three-dimensional space with multiple degrees of freedom. Compared with traditional fixed cooling fans, this solution can accurately target the cooling airflow to heat-generating equipment at any position and height, significantly improving the targeting and efficiency of heat dissipation.

[0066] In this embodiment, the turntable 32 has a through groove at its center, a gear ring 321 is provided in the through groove, a servo motor 36 is fixed in the base 31, and a gear that meshes with the gear ring 321 is provided at the output end of the servo motor 36.

[0067] When the horizontal orientation of the air supply component 35 needs to be adjusted, the servo motor 36 starts after receiving a control signal, driving the gear at its output end to rotate. The gear meshes with the gear ring 321, causing the gear ring 321 to rotate. Since the gear ring 321 is fixed to the inner wall of the through groove of the turntable 32, the rotation of the gear ring 321 causes the turntable 32 to rotate synchronously around the vertical central axis of the base 31.

[0068] In this embodiment, the orientation component 34 includes:

[0069] A connecting seat 341 is rotatably mounted on the lifting end and driven by a rotating motor. A deflection motor is provided on the connecting seat 341.

[0070] Deflection seat 342 is fixed to the output end of the deflection motor;

[0071] The connecting shaft 343 serves as the adjusting end and is connected between the deflection seat 342 and the air supply assembly 35.

[0072] The rotation center axis of the connecting seat 341 is perpendicular to the vertical center axis of the base 31. The output end of the deflection motor can drive the deflection seat 342 to deflect up and down, and the deflection center axis of the deflection seat 342 is perpendicular to the rotation center axis of the connecting seat 341.

[0073] Thus, the directional assembly 34 provides two mutually perpendicular degrees of deflection freedom: one provided by the rotation of the connecting seat 341 about the horizontal axis, and the other by the up-and-down deflection of the deflector seat 342 about another axis perpendicular to the horizontal axis. Combined with the rotation of the turntable 32 about the vertical central axis, the air supply assembly 35 can point in any direction in three-dimensional space, meeting the precise air supply needs of electrical equipment at different locations and heights within the temperature control area.

[0074] In this embodiment, the air supply assembly 35 includes:

[0075] The air supply chamber 351 is fixed to the directional end and connected to an external air supply device through an external pipe.

[0076] Installation compartment 356 is installed on one side of the air supply compartment 351;

[0077] The air supply pipe 352 is connected to the air supply chamber 351 at one end via a flexible pipe. The air supply pipe 352 is also rotatably connected to the installation chamber 356 via a directional shaft 353 and is driven by a micro motor.

[0078] A first valve body is provided at the connection between the air supply chamber 351 and the flexible pipe.

[0079] The external air supply device is, for example, either a blower or an air compressor. The airflow generated by the external air supply device enters the air supply chamber 351 through the air supply pipe. The external pipe is, for example, either a flexible corrugated pipe or a rubber hose, capable of adapting to the positional changes of the air supply chamber 351 during the reversing process.

[0080] During implementation, the micro motor drives the air supply pipe 352 to rotate around the adjustment shaft 353, thereby adjusting the air outlet direction of the air supply pipe 352, so that multiple air supply pipes 352 supply air in a concentrated or diffused manner.

[0081] In this embodiment, a temperature instrument is embedded in the air supply chamber 351, and an exhaust port 355 is provided in the middle of the air supply chamber 351, and a second valve body is provided in the exhaust port 355.

[0082] A cooler 357 is provided in the middle of the installation compartment 356. The side of the cooler 357 is made of heat-conducting material. A slip ring 358 is slidably sleeved on the side of the cooler 357. A flexible heat insulation sleeve is connected between the slip ring 358 and the bottom of the cooler 357. A spring 359 is also connected between the slip ring 358 and the bottom of the cooler 357.

[0083] The surface of the air supply pipe 352 is provided with multiple through holes 354;

[0084] When the thermometer detects that the gas temperature is greater than a preset threshold, the first valve body is closed and the second valve body is opened.

[0085] In ventilation mode, the first valve is open and the second valve is closed. Airflow from the external air supply unit enters the air supply chamber 351 through the external connecting pipe, then flows through the flexible pipe into the air supply pipe 352 and is discharged, providing ventilation and heat dissipation to the temperature-controlled area. The cooler 357 is not operating at this time.

[0086] When the temperature gauge detects that the gas temperature inside the air supply chamber 351 exceeds the preset threshold, it indicates that simple ventilation and heat dissipation are insufficient to control the temperature, and the system automatically switches to cooling mode: closing the first valve and opening the second valve. Simultaneously, the cooler 357 starts cooling. The cooler 357 releases cooling energy into the air inside the installation chamber 356 through the side of its heat-conducting material. The cooled air then enters the air supply pipe 352 through the through-hole 354 and is discharged.

[0087] During the refrigeration process, the slip ring 358, spring 359, and flexible insulation sleeve work together to adjust the effective refrigeration area of ​​the cooler 357. The spring 359 applies an elastic thrust to the slip ring 358, causing the slip ring 358 to cover a portion of the side of the cooler 357. The area covered by the slip ring 358 is insulated from the outside by the flexible insulation sleeve and does not participate in heat exchange; the uncovered area is exposed to the air inside the mounting chamber 356 and participates in heat exchange. When the first valve body is closed and the second valve body is opened, the gas flowing from the exhaust port 355 to the through hole 354 pushes the slip ring 358, compressing the spring 359. This reduces the area covered by the slip ring 358, while the uncovered area is exposed to the air inside the mounting chamber 356 and participates in heat exchange.

[0088] In this embodiment, the cooler 357 is a semiconductor cooler or a phase change cooler. When the cooler 357 is a phase change cooler, external airflow can be introduced through the exhaust port 355 at night to cool the phase change cooler.

[0089] It should be explained that phase change materials absorb a large amount of heat during the solid-liquid phase change process while maintaining a relatively constant temperature, exhibiting high energy storage density and stable temperature control. During the day, when heat dissipation demand is high, the phase change material absorbs heat and melts, providing a continuous cooling effect. At night, the ambient temperature naturally decreases, allowing external airflow to be introduced through exhaust port 355 to cool the phase change refrigerator. The cooler external airflow flows through the cooler 357, carrying away the heat stored in the phase change material, causing it to re-solidify and restore its cooling capacity. This process utilizes the natural condition of the diurnal temperature range, requiring no additional cooling energy consumption.

[0090] Alternatively, in one embodiment, a semiconductor cooler may be selected, which is suitable for applications requiring rapid response and precise temperature control.

[0091] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
