Description

Technical Field

[0001] This utility model relates to the field of intelligent melting terminal technology for transformer substations, specifically an intelligent transformer substation terminal with self-testing and self-recovery capabilities. Background Technology

[0002] The intelligent converged terminal for distribution transformers is installed on the secondary side of transformers in substation rooms, box-type substations, or pole-type substations. It is an edge device in the "cloud-pipe-edge-device" architecture of the smart IoT system. It is mainly used to monitor the operating conditions of distribution transformers, including operating parameters such as voltage, current, power, frequency, power consumption, harmonics, and power outage events. It is a converged terminal device that integrates functions such as distribution transformer power supply and consumption information collection, data collection from various acquisition terminals or electricity meters, equipment status monitoring and communication networking, local data storage and decision analysis, and collaborative computing.

[0003] The distribution terminal contains various electrical components. Due to the different working characteristics of these components, the heat generated during their operation will also vary. For example, the temperature of the storage module will rise significantly during data upload and storage, and the temperature of the remote control module will rise significantly during remote control. Therefore, current heat dissipation methods generally target the entire distribution terminal. When dissipating heat from the whole, airflow will flow to various areas, resulting in a relatively balanced heat dissipation effect. However, when only a few modules have high temperatures, it is not possible to quickly and specifically cool them down. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-9 As shown, the device includes a housing 10 and an outer cover 11. An electrical mounting plate 20 is installed inside the housing 10. Several electronic components are installed on the electrical mounting plate 20, including a communication module, power supply, acquisition components, storage components, core processor, etc. The user's power usage is monitored through the cooperation of multiple electronic components. After use, various electronic components will generate a lot of heat. Since different electronic components generate different amounts of heat, the heat in different parts inside the housing 10 is different. The bottom of the housing 10 is divided into at least two modules, preferably four modules, covering the entire bottom of the housing 10. Each module is provided with a heat dissipation copper pipe 30. A heat dissipation switching component is provided at the center of the housing 10. A temperature sensing component corresponding to the heat dissipation copper pipe 30 is provided on the electrical mounting plate 20.

[0019] The temperature sensing component includes a temperature sensing column 201 and an electro-hydraulic column 202, which are connected by a connecting pipe 203. The electrical mounting plate 20 is hollow. The temperature sensing components are evenly distributed around the heat sink 31. The temperature sensing column 201 is located in the middle of the heat dissipation copper pipe 30 to monitor the temperature at this location. The temperature sensing column 201 is located on the side away from the heat sink 31, while the hydraulic column 202 is located on the side closer to the heat sink 31. Both the temperature sensing column 201 and the hydraulic column 202 are hollow inside. Electrical mounting plates 204 are threaded onto the four sides of the electrical mounting plate 20 for fixing the electrical mounting plate 20. A temperature sensor is installed on the temperature sensing column 201, and the temperature sensor is connected to the motor signal on the fan blade 311 inside the heat sink 31. A push plate 201 is installed inside the temperature sensing column 201. 1. The internal cavity is divided into two parts by the push plate 2011. The side closer to the electrical mounting plate 20 contains paraffin wax, while the side farther from the electrical mounting plate 20 contains hydraulic oil. A hydraulic push rod 2021 is installed inside the hydraulic column 202. The hydraulic push rod 2021 passes through the electrical mounting plate 20 and abuts against the heat sink 31. The hydraulic oil in the temperature sensing column 201 flows into the hydraulic column 202 through the connecting pipe 203 to push the hydraulic push rod 2021. When the temperature at the corresponding position inside the housing 10 rises, the paraffin wax melts and squeezes the hydraulic oil, which in turn drives the hydraulic push rod 2021 to move. Moreover, the trigger temperature of the temperature sensor is the same as the melting temperature of the paraffin wax, which is 40-60℃. The temperature of different modules inside the housing 10 can be monitored by the temperature sensing column 201, and corresponding reactions can be generated according to different temperatures.

[0020] The bottom of the outer casing 10 has an air intake slot 101 with a hollow bottom, which communicates with the interior of the heat sink 31. The heat dissipation switching assembly includes the heat sink 31, one end of the heat dissipation copper pipe 30 is connected to the heat sink 31, a fan blade 311 is installed inside the heat sink 31, and a baffle is also installed inside the heat sink 31 at the connection between the heat dissipation copper pipe 30 and the heat sink 31. The heat dissipation copper pipe 30 is bent and filled into the bottom of the outer casing 10. One end of the heat dissipation copper pipe 30 is connected to the heat sink 31, and the other end extends to the outside. The heat sink 31 has a fan blade 311 and a fan 312 installed inside the heat sink 31. The fan blade 311 is located inside the heat sink 31, and the fan 312 is located outside the heat sink 31 and is connected to all temperature sensor signals. When the fan blade 311 rotates, it draws air in through the hollow of the air intake slot 101, and then the fan blades on the fan blade 311 throw the air outwards. The heat sink 31 also has at least two baffles 313 installed inside the heat sink 31. Corresponding to the heat dissipation copper pipe 30, the baffle 313 is located on the outer periphery of the fan blade 311. The bottom of the baffle 313 is fixed to the inner wall of the heat sink 31 by a spring. After any temperature sensor is activated, it can transmit a signal to start the fan 312 to drive the fan blade 311 to rotate. At this time, the paraffin of the temperature sensing column 201 at the corresponding position melts, which can drive the hydraulic push rod 2021 to abut against the baffle 313, so that the baffle 313 compresses the spring and opens the channel between the heat sink 31 and the heat dissipation copper pipe 30. At this time, the air generated by the fan blade 311 will flow out from the heat dissipation copper pipe 30 to cool down the heat dissipation copper pipe 30, greatly reducing the temperature around the heat dissipation copper pipe 30. At this time, the temperature at the corresponding position inside the outer casing 10 is higher, and heat exchange will occur, so that the heat flows from the higher place to the lower place. That is, the heat of the electronic components flows to the heat dissipation copper pipe 30 through the electrical mounting plate 20, and then the heat dissipation copper pipe 30 absorbs the heat and is carried out by the airflow to complete the cooling effect.

[0021] By configuring multiple heat dissipation copper pipes 30 and heat dissipation switching components, when the temperature of one module inside the casing 10 rises, only that module's cooling operation is activated. This concentrates all the airflow generated within the heat sink 31 into the heat dissipation copper pipe 30, significantly increasing the airflow velocity within the heat dissipation copper pipe 30 and thus enhancing the cooling effect. When multiple locations experience simultaneously high temperatures, all cooling operations are automatically activated gradually to cool the entire interior of the casing 10. However, due to airflow diversion, the airflow within each heat dissipation copper pipe 30 decreases, resulting in a reduced cooling effect compared to cooling a single module. Therefore, the terminal can automatically detect temperature levels in multiple locations and adaptively implement different levels of cooling based on the varying heat output of different electrical components. For electrical components in a single module that heat up rapidly, a separate rapid cooling method is used to lower the temperature of that component, allowing it to automatically return to its normal operating temperature.

[0022] Working principle: During use, electrical components are installed at different positions on the electrical mounting plate 20 according to different modules. However, the heat generated by one electrical component is higher than that of other components. At this time, the ambient temperature at this location will rise, causing the paraffin inside the temperature sensing column 201 to melt. At the same time, the temperature sensor will start the fan 312, which will drive the fan blade 311 to rotate. The melting paraffin inside the temperature sensing column 201 will drive the hydraulic push rod 2021 to abut against the baffle 313 and compress the spring, opening the channel of the heat dissipation copper pipe 30 at this location. This allows the airflow generated by the fan blade 311 to enter the heat dissipation copper pipe 30 at this location. The airflow generated at this time is large, which can quickly cool down this location and rapidly reduce the temperature of the electrical components at this location.

[0023] As usage continues, the temperature of other surrounding electrical components will also rise, gradually surpassing the temperature of the aforementioned electrical components. At this time, the paraffin wax in the corresponding temperature sensing columns 201 will also melt, thus providing a large-scale cooling effect on the electrical components inside the casing 10. In summary, by setting the heat dissipation switching component, when the temperature of a single module is high, the fan blades 311 can provide concentrated cooling at this location, resulting in a good cooling effect. When the temperature of multiple modules is high, the fan blades 311 can still provide large-area cooling to multiple locations, resulting in a large cooling range.

[0024] In summary, this intelligent distribution terminal, equipped with self-testing and self-recovery capabilities, can automatically detect temperature levels in multiple locations. Based on the varying heat output of different electrical components, it adaptively achieves different levels of cooling. For electrical components in a single module that heats up rapidly, it uses a dedicated rapid cooling system to lower the temperature of that component, allowing it to automatically return to its normal operating temperature. Through the cooling switching component settings, when a single module's temperature is high, the fan blades 311 can provide concentrated cooling, resulting in good cooling performance. When multiple modules have high temperatures, the fan blades 311 still provide large-area cooling across multiple locations, resulting in a wide cooling range.
