Description

Technical Field

[0001] This utility model relates to the field of prefabricated substations, and more specifically, to a prefabricated substation that facilitates heat dissipation. Background Technology

[0002] A prefabricated substation is an outdoor complete set of power distribution equipment that organically combines multiple functions such as high-voltage power reception, transformer voltage reduction, and low-voltage power distribution. It mainly consists of high-voltage switchgear, transformer, and low-voltage switchgear, and is usually assembled as a whole in a closed enclosure.

[0003] In practical applications of prefabricated substations, a common heat dissipation method is to create ventilation openings on the enclosure to allow air circulation with the outside air, thereby achieving heat dissipation. Specifically, this relies on the principle of natural ventilation, allowing relatively cool outside air to enter the prefabricated substation through the ventilation openings. After exchanging heat with the internal heat-generating electrical equipment, the warmed air is then exhausted to the outside through other ventilation openings, thus maintaining the internal temperature of the prefabricated substation within a relatively reasonable range.

[0004] However, this heat dissipation method has significant drawbacks. Because the interior of a prefabricated substation houses numerous components such as transformers, switchgear, and various supporting structures, these components in the central area significantly obstruct airflow. When hot air tries to escape from this central area, it cannot flow smoothly due to these obstructions. This prevents the heat generated in this area from being carried away from the environment as quickly as in more open areas like near vents, causing heat to accumulate continuously in the central region. Electrical components typically have optimal operating temperature ranges. Prolonged exposure to excessively high temperatures can lead to problems such as decreased insulation performance and accelerated component aging. Ultimately, components located in this central area are highly susceptible to heat-related damage, severely impacting the normal operation of the prefabricated substation.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a prefabricated substation that facilitates heat dissipation. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a box-type substation that is easy to dissipate heat.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated substation for easy heat dissipation, comprising a prefabricated substation body, wherein an air flow channel is embedded inside the prefabricated substation body and runs through both sides of the prefabricated substation body. The air flow channel is rectangular and its four sides are all composed of heat conduction plates. The surface of the heat conduction plate facing the prefabricated substation body is designed as fins.

[0008] Preferably, a base is fixedly connected to the bottom of the main body of the prefabricated substation, which can support the main body of the prefabricated substation to a certain height and prevent its bottom from getting damp.

[0009] Preferably, a suction fan for air intake is installed on one side of the main body of the box-type substation, and a ventilation slot communicating with the outside is opened on the other side.

[0010] Preferably, the surfaces of the suction fan and the ventilation slot are equipped with rain covers to prevent rainwater from entering the main body of the box-type substation.

[0011] Preferably, the fins of the heat conduction plate are composed of heat sinks of varying heights that decrease first and then increase, which further optimizes the heat dissipation effect.

[0012] Preferably, a temperature alarm device is installed on the main body of the prefabricated substation to monitor the temperature inside the main body of the prefabricated substation.

[0013] Preferably, the temperature alarm device includes:

[0014] Temperature sensor: It is installed inside the main body of the prefabricated substation to detect the temperature inside the main body of the prefabricated substation and transmit these temperature signals to the controller in real time.

[0015] Controller: Based on the signal input from the temperature sensor, when the temperature reaches the critical point, it sends a command to the LOAR wireless transmission module to send a signal to the outside world;

[0016] LOAR wireless transmission module: used to transmit alarm information processed by the controller to the monitoring software backend for real-time display;

[0017] Power supply: Provides power to the electrical components on the main body of the prefabricated substation.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This utility model sets up multiple air flow channels as described above inside the main body of the prefabricated substation. Since the air flow channels run through both sides of the prefabricated substation, natural wind can pass through the air flow channels without obstruction. The fin-shaped design of the heat conduction plate greatly expands the contact area between the heat sink and the hot air and flowing cold air inside the main body of the prefabricated substation. Heat is transferred to the heat conduction plate through heat conduction, and then quickly transferred to the outside through natural wind to dissipate heat from the prefabricated substation. This avoids obstruction by components in the prefabricated substation, and allows the central area to dissipate heat quickly and effectively, thereby solving the problem of the difficulty in quickly dissipating heat in the central area of ​​the main body of the prefabricated substation in the background art.

[0020] 2. The suction fan and ventilation slot of this utility model are located on both sides of the main body of the box-type substation, forming a relatively ideal air circulation path. This allows cold air to be drawn in from one side and flow fully inside the main body of the box-type substation, exchanging heat with various electrical equipment. Then, the hot air is discharged from the ventilation slot on the other side, realizing good air circulation inside the main body of the box-type substation, thereby ensuring that the electrical equipment can operate stably in a suitable temperature environment.

[0021] 3. This utility model installs a temperature alarm device on the main body of the prefabricated substation to monitor the temperature inside the main body of the prefabricated substation, so as to grasp the heat generation of the equipment in a timely manner and provide a basis for subsequent heat dissipation control.

[0029] like Figure 1-5As shown, this utility model provides a prefabricated substation with convenient heat dissipation, including a prefabricated substation body 1. An air flow channel 2 is embedded inside the prefabricated substation body 1, running through both sides of the prefabricated substation body 1. The air flow channel 2 is rectangular, and its four sides are all composed of heat conduction plates 201. The surface of the heat conduction plates 201 facing the prefabricated substation body 1 is designed as fins. A base 3 is fixedly connected to the bottom of the prefabricated substation body 1. The base 3 is made of cast iron material, which has a high density and is heavier than ordinary materials for the same volume. It can stably support the prefabricated substation body 1 and also support the prefabricated substation body 1 to a certain height to prevent its bottom from getting damp.

[0030] This invention provides multiple airflow channels 2 as described above inside the main body 1 of the prefabricated substation (the number of airflow channels 2 is selected as needed, preferably close to the electrical components inside the main body 1 of the prefabricated substation, so as to quickly remove the heat from them). Since the airflow channels 2 run through both sides of the prefabricated substation, natural wind can pass through the airflow channels without obstruction. The fin-shaped design of the heat conduction plate 201 greatly expands the contact area between the heat sink 202 and the hot air and flowing cold air inside the main body 1 of the prefabricated substation. Heat is transferred to the heat conduction plate 201 (made of thermally conductive material) through thermal conduction, and then quickly transferred to the outside through natural wind to dissipate heat from the prefabricated substation. This avoids obstruction by components in the prefabricated substation, so that the central local area can also dissipate heat quickly and effectively.

[0031] The heat conduction plate 201 is composed of heat sinks 202 of varying heights, which decrease first and then increase. The varying heights of the heat sinks 202 further optimize the heat dissipation effect. This unique height variation allows the heat sinks 202 to present different spatial forms in different areas. Compared with heat sinks 202 of uniform height, it can make fuller use of the three-dimensional space inside the main body 1 of the box-type substation. At the same time, when the heat conduction plate 201 receives heat from the electrical equipment in the box-type substation, the heat will not be concentrated in one place, but will be distributed more evenly to various small areas according to the distribution of the heat sinks 202, thereby further increasing the overall heat dissipation area and allowing more heat to be transferred from the heat conduction plate 201 to the surrounding air.

[0032] Furthermore, a suction fan 4 for air intake is installed on one side of the main body 1 of the prefabricated substation, and a ventilation slot 5 connecting to the outside is opened on the other side. First, the suction fan 4 can actively and forcefully draw cold air from the outside into the main body 1 of the prefabricated substation. Compared with relying solely on natural ventilation, this can greatly increase the air intake volume, ensuring sufficient cold air to participate in heat exchange and promptly remove the heat generated by electrical equipment, effectively improving heat dissipation efficiency. Second, the ventilation slot 5 provides a stable and smooth exhaust channel for hot air, allowing the heated air after heat exchange to be quickly and orderly discharged into the outside environment, preventing hot air from accumulating inside the main body 1 of the prefabricated substation and causing excessively high temperatures. Furthermore, the suction fan 4 and the ventilation slot 5 are located on both sides of the main body 1 of the prefabricated substation, forming a relatively ideal air circulation path. This allows cold air to be drawn in from one side and flow fully inside the main body 1 of the prefabricated substation, exchanging heat with various electrical equipment. Then, the hot air is discharged from the ventilation slot 5 on the other side, achieving good air circulation within the main body 1 of the prefabricated substation. This ensures that the electrical equipment can operate stably in a suitable temperature environment, extends its service life, and reduces the risks of equipment failure and safety hazards that may be caused by high temperatures.

[0033] Furthermore, rain covers 6 are installed on the surfaces of the suction fan 4 and the ventilation duct 5 to prevent rainwater from entering the prefabricated substation through the area where the suction fan 4 and the ventilation duct 5 connect with the main body 1 of the prefabricated substation.

[0034] Finally, this utility model also installs a temperature alarm device 7 on the main body 1 of the prefabricated substation to monitor the temperature inside the main body 1 of the prefabricated substation, so as to grasp the heat generation of the equipment in a timely manner and provide a basis for subsequent heat dissipation control. The temperature control device includes a temperature sensor, a controller, a LOAR wireless transmission module and a power supply.

[0035] First, the temperature sensor is precisely installed inside the main body 1 of the prefabricated substation. It continuously performs its function of monitoring the temperature in various areas within the main body 1 in real time. Once temperature data is detected, it quickly and continuously transmits these temperature signals to the controller, providing accurate information for subsequent judgment and processing. Next, after receiving the signals from the temperature sensor, the controller immediately analyzes and processes them. When the monitored temperature reaches a pre-set critical point, the controller, according to its pre-set program logic, sends a command to the LOAR wireless transmission module to send a signal to the outside world, triggering subsequent alarm information transmission. Subsequently, after receiving the command from the controller, the LOAR wireless transmission module accurately transmits the alarm information, including temperature anomalies, to the monitoring software backend via wireless transmission. This allows the alarm information to be displayed in real time on the monitoring software backend, enabling relevant personnel to promptly obtain information about abnormal temperatures inside the prefabricated substation. Simultaneously, the power supply continuously and stably powers the components on the main body 1 of the prefabricated substation, such as the temperature sensor, controller, and LOAR. Power is supplied to all electrical components, including the wireless transmission module, to ensure that each component can operate normally.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
