[0002] With the acceleration of global urbanization, power grids need to extend to remote areas (such as mountains and islands). Traditional indoor substations are costly and time-consuming to build, while outdoor transformers can be installed directly exposed to the environment, significantly reducing infrastructure difficulties. In urban underground utility tunnels or power distribution scenarios with narrow spaces, compact outdoor transformers can save space and enable rapid deployment.

[0003] Chinese patent CN206401150U discloses a system transformer that, based on its own structure, can effectively control electrical pollution inside and outside the power grid while distributing power. It reduces heat generation, vibration, friction, line loss, copper loss, iron loss, noise, and transformer losses within the power distribution system, achieving system energy saving for all equipment, instruments, lines, switches, etc. within the power distribution system. However, this is an integrated circuit structure, i.e., a traditional indoor substation. The transformer structure is connected to other auxiliary circuits, and it is not possible to quickly replace components when they malfunction, resulting in some power outage losses.

[0032] like Figure 1 As shown, a modular transformer system includes an electrical pollution monitoring box 1, which is equipped with a data processing device for controlling and displaying transformer system information. The system also includes a modular transformer 2, which comprises a housing 201 and a modular working section. The housing 201 has a placement cavity 204, and the modular working section is placed within the placement cavity 204. The modular working section is signal-connected to the data processing device in the electrical pollution monitoring box 1. The modular working section integrates a transformer 6 and a Hall effect resonator 5, and the transformer 6 and the Hall effect resonator 5 are detachably connected.

[0033] The purpose of this design is to separate the data processing section, the transformer section and other functional sections using a modular structure, which supports the rapid replacement of faulty components, reduces power outage losses, and solves the problem of traditional indoor substations where the transformer structure is connected to other auxiliary circuits, making it impossible to quickly replace components when they malfunction, resulting in certain power outage losses.

[0034] It should be noted that the data processing device is a reuse of existing technology in this application, and its specific working principle is disclosed in Chinese Patent Publication No. CN111681863A, such as... Figure 8 As shown, the data processing device is connected to existing modular components such as current detection device, voltage detection device, frequency detection device, data display device, data transmission interface, data storage device, and abnormal alarm device.

[0035] The current detection device is used to detect the real-time current information of the power line between the transformer secondary coil and the electrical load end and send it to the data processing device.

[0036] The voltage detection device is used to detect the real-time voltage information of the power line between the transformer secondary coil and the electrical load end and send it to the data processing device.

[0037] The frequency detection device is used to detect the real-time frequency information of the power line between the transformer secondary coil and the electrical load end and send it to the data processing device.

[0038] The data storage device is used to store the real-time current information, real-time voltage information, and real-time frequency information, and is also used to store the threshold current information, threshold voltage information, and threshold frequency information of the power line between the transformer secondary coil and the electrical load end.

[0039] The data processing device is used to compare and judge the real-time current information, real-time voltage information, and real-time frequency information with the threshold current information, threshold voltage information, and reading frequency information, respectively, and send the comparison and judgment results to the data display device and the data transmission interface.

[0040] The data display device is used to display the real-time current information, real-time voltage information, and real-time frequency information, and also to display the comparison and judgment results;

[0041] The data transmission interface is used to transmit the real-time current information, real-time voltage information, real-time frequency information, and comparison and judgment results to the remote monitoring device.

[0042] The anomaly alarm device is used to issue anomaly alarms under the control of the data processing device.

[0043] In this embodiment, in order to expand the entire modular transformer system, multiple modular transformers 2 are also included, and the modular working part in each modular transformer 2 is connected to the data processing device in the electrical pollution monitoring box 1. In this way, multiple functions can be achieved by integrating multiple modular transformers 2 in complex scenarios.

[0044] like Figure 6 and Figure 7 As shown, combining the two can form a complete circuit diagram of a modular transformer system, wherein in Figure 6 The circuit includes a modular power input section, a metering section, a low-voltage input section, and a dual power supply switching section. In the entire circuit, the dual power supply switching section is used to provide power through a diesel generator when there is a problem with the mains power supply.

[0045] exist Figure 7 Part of it integrates multiple modular transformers, each with an independent transformer circuit structure, which are connected through auxiliary circuits.

[0046] It should be noted that the Hall resonator 5 referred to in this embodiment integrates a Hall effect resonant rod, the specific details of which are disclosed in Chinese Patent No. CN113972647B. It can control the reactance filter to adjust the line by judging whether the frequency detection is normal after the transformer is working; and control the compensation capacitor group to adjust the line by judging whether the power detection is normal. Furthermore, based on the adjustment, both frequency adjustment and power adjustment are checked, and the adjustment process is accurately fed back, which can effectively avoid subsequent power transmission accidents caused by abnormal adjustment.

[0047] Returning to the specific structural details, in this embodiment, as follows: Figures 2 to 5 As shown, the box 201 has an opening on one side, and a first movable door 9 and a second movable door 10 are provided at the opening. The first movable door 9 and the second movable door 10 are respectively located at the left and right ends of the opening on one side of the box 201 via door hinges 13. The second movable door 10 can cover the first movable door 9 and be locked. A third ventilation mesh 14 is provided on the first movable door 9, and the third ventilation mesh 14 connects the placement cavity 204 with the external environment.

[0048] The purpose of this design is that, since the entire modular working unit is placed inside the enclosure, an opening, i.e., a door structure, is provided on one side of the enclosure. In use, the enclosure is opened by opening the first and second movable doors, and the entire modular working unit is placed inside. After the wiring is completed, the first and second movable doors are closed. It should be noted that the specific locking method here is as follows: after the modular working unit is placed, the first movable door is closed first, and then the second movable door is placed on top of the first movable door, with a certain overlap between the two. Finally, the two are connected by existing structures such as a connecting lock.

[0049] In this embodiment, the two opposite sides of the box 201 are respectively provided with a first protrusion 202 and a second protrusion 203, and a first breathable mesh 3 is provided on the first protrusion 202, and the first breathable mesh 3 connects the placement cavity 204 with the external environment.

[0050] The second protrusion 203 is provided with a second breathable mesh 4, and the second breathable mesh 4 connects the placement cavity 204 with the external environment.

[0051] The purpose of this design is to adapt to the needs of outdoor scenarios. The main problem with components such as transformers is that they generate a lot of heat during operation. On the one hand, the set ventilation mesh can connect with the external environment to achieve heat exchange. On the other hand, based on the fan structure set in the box itself, hot air can be circulated quickly.

[0052] In this embodiment, the modular transformer 2 also includes a base plate 205, and the base plate 205 is provided with a through hole 12, and the external wires can pass through the through hole 12 into the placement cavity 204 and connect with the modular working part. A pair of square pillars 11 are provided on the side of the base plate 205 facing away from the modular working part, and the pair of square pillars 11 are arranged in parallel and lift up the modular transformer 2. There is a gap between the bottom of the modular transformer 2 and the ground.

[0053] The purpose of this design is to allow external cables to easily enter the placement cavity from the bottom by setting perforations, while the square pillars raise the entire modular transformer off the ground for protection.

[0054] It should be noted that in this embodiment, the external cable extends into the placement cavity. In actual implementation, it can also extend into the placement cavity from the top or other directions. In this case, the perforation can be used for heat dissipation, ventilation, or drainage.

[0055] In this embodiment, a limiting protrusion 8 is provided on the side of the base plate 205 facing the modular working part, and the limiting protrusion 8 can limit the base 7.

[0056] The purpose of this design is that, in most usage scenarios, the entire modular working unit will not shake or shift after installation. However, it may move during unavoidable impacts or ground vibrations. Therefore, by setting a limiting protrusion and a matching limiting groove on the base, the connection between the two is strengthened by inserting the limiting protrusion into the limiting groove, reducing the probability of internal movement in the event of an accident.

[0057] It should also be noted that the modular transformer provided in this embodiment mainly combines its transformation and protection functions in a modular way. When implementing this solution, those skilled in the art can further combine it with other modular components to achieve other additional functions, such as with a power outage intelligent switching device, which can automatically and intelligently switch to the diesel generator system within 2-4 minutes to meet power supply needs, or install an energy consumption data acquisition device to achieve 24 / 7 real-time energy consumption monitoring for intelligent early warning and real-time monitoring. At the same time, through artificial intelligence technology, MQTT message queue communication technology, OpenCV intelligent face recognition technology, access control alarm and portrait capture technology, smoke alarm technology, real-time temperature and humidity data acquisition technology, IoT Internet of Things technology, etc., real-time security monitoring can be achieved. Alternatively, it can be combined with a remote early warning and monitoring platform with a dedicated mobile app, which can provide real-time remote monitoring for 3-5 people, and perform all-weather control of energy consumption, carbon emissions, temperature, humidity, door imaging, etc., to achieve unmanned daily management, thereby reducing management and maintenance personnel, reducing operating costs, and increasing economic and social benefits.

[0058] The above-mentioned content requires those skilled in the art to select existing functional modules for installation and integration. This embodiment only provides a functional description and is not intended to provide a specific connection solution.

[0059] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
