[0032] In this embodiment, specifically: the box-type housing is a cuboid with an inclined roof structure, and its interior is divided into three compartments by two groups of partitions 101, namely a high-voltage compartment, a transformer compartment, and a low-voltage compartment, and these three compartments are arranged in a horizontal "eye" shape.

[0033] First, the high-voltage switchgear is arranged in the high-voltage compartment and is responsible for processing and controlling the work of the high-voltage power supply part.

[0034] The transformer is arranged in the transformer room for power transformation and distribution. The low-voltage complete cabinet is arranged in the low-voltage room and is responsible for outputting power from the transformer to the user terminal.

[0035] In addition, smart network cameras and air-conditioning equipment are located on the top of the transformer room. The smart network cameras use monitoring technology to monitor the situation around the substation in real time to ensure safety and reliability, while the air-conditioning equipment is used to adjust the temperature and humidity in the transformer room to ensure the normal operating environment of the equipment.

[0036] The layout and component installation of the entire box-type substation allow different functional modules to be distributed relatively independently in different compartments, avoiding mutual interference and cross-contamination. At the same time, the compact design of the box-type shell makes the substation occupy less space, making it suitable for use in limited site conditions.

[0037] In general, this intelligent compact box-type substation realizes the integration and control of high-voltage, transformer and low-voltage power systems through reasonable compartment layout and functional module configuration, providing a safe, efficient and reliable power supply environment.

This arrangement and connection realizes the intelligent control integration of the box-type substation, and realizes the sending and receiving of fault and fire alarm information of the box-type substation and remote monitoring and control operations.

[0039] In this embodiment, specifically: the system is composed of multiple devices such as intelligent microcomputer protection devices, temperature and humidity sensors, intelligent network cameras, air-conditioning equipment and temperature sensors, and is connected as an integrated control system through electrical connections and Ethernet or wireless communications. The system realizes the intelligent control integration of box-type substations, including fault and fire alarm information sending and receiving, remote monitoring and control operations and other functions.

[0040] First, the intelligent microcomputer protection device is arranged in the high-voltage complete cabinet, which is responsible for protecting and controlling the high-voltage circuit. At the same time, the temperature and humidity sensor is also installed in this position to detect the temperature and humidity inside the high-voltage complete cabinet in real time. The intelligent network camera and air conditioning equipment are arranged in the transformer room. The former monitors the situation around the transformer room in real time through monitoring technology, and the latter is used to adjust the temperature and humidity of the transformer room. In addition, the temperature sensor is arranged in the low-voltage complete cabinet, which is also used to detect the temperature inside the low-voltage complete cabinet in real time.

[0041] These devices are connected as an integrated control system through electrical connection and Ethernet or wireless communication to achieve data acquisition and monitoring control. Through data exchange and processing within the system, the operation of the box-type substation can be remotely monitored, and faults can be discovered and handled in time. At the same time, it can also receive fire alarm information in real time and send relevant emergency instructions for processing. In addition, through remote control operations, the box-type substation can also be dispatched and controlled to achieve an intelligent operation mode.

[0042] In short, the arrangement and connection of the data acquisition and monitoring control system realizes the comprehensive monitoring and remote control of the intelligent compact box-type substation, making the operation safer, more stable and efficient.

[0043] In one embodiment, the high-voltage complete cabinet 2 is formed by high-voltage V cabinet 201, F cabinet 202, C cabinet 203 and D cabinet 204 units electrically connected through a busbar; the low-voltage complete cabinet 4 is formed by a low-voltage incoming cabinet 401 and a low-voltage outgoing cabinet 402 electrically connected through a busbar.

[0044] The high voltage D cabinet 204 unit is electrically connected to the high voltage terminal 301 of the transformer 3 through the busbar; the low voltage incoming line cabinet 401 is electrically connected to the low voltage terminal 302 of the transformer 3 through the busbar 303.

[0045] In this embodiment, specifically: the high-voltage complete cabinet 2 in the box-type substation is formed by the high-voltage V cabinet, F cabinet, C cabinet and D cabinet units being electrically connected through the busbar, and the low-voltage complete cabinet 4 is formed by the low-voltage incoming cabinet and the low-voltage outgoing cabinet being electrically connected through the busbar. The high-voltage D cabinet 204 unit is electrically connected to the high-voltage terminal 301 of the transformer 3 through the busbar, and the low-voltage incoming cabinet 401 is electrically connected to the low-voltage terminal 302 of the transformer 3 through the busbar 303.

[0046] From the perspective of electrical connection, the V, F, C and D cabinet units in the high-voltage complete cabinet are connected together through the busbar to form a high-voltage circuit. At the same time, the incoming cabinet and the outgoing cabinet in the low-voltage complete cabinet are also connected together through the busbar to form a low-voltage circuit. The high-voltage D cabinet 204 unit is electrically connected to the high-voltage terminal 301 of the transformer 3, and the low-voltage incoming cabinet 401 is electrically connected to the low-voltage terminal 302 of the transformer 3. In this way, the electric energy enters the D cabinet unit of the high-voltage complete cabinet from the high-voltage side of the transformer 3, passes through the various units of the high-voltage circuit, and finally reaches the low-voltage incoming cabinet, and then enters the low-voltage circuit, and finally sent out of the box-type substation.

[0047] From the working principle point of view, high-voltage and low-voltage complete cabinets are two key parts in the box-type substation. The high-voltage complete cabinet is responsible for importing the high-voltage output signal of the transformer 3 into the box-type substation. After being processed by each unit, it is sent to the low-voltage complete cabinet through the low-voltage incoming cabinet. The low-voltage complete cabinet sends the low-voltage output signal to the load end to achieve effective distribution and control of electric energy. The whole process needs to ensure the safety and reliability of the electrical connection, as well as the coordination and cooperation between the various units to ensure the normal operation of the box-type substation.

[0048] In one embodiment, the high-voltage complete cabinet 2 is an environmentally friendly gas-filled cabinet. Compared with the existing air-insulated cabinet, the environmentally friendly gas-filled cabinet is smaller in size and is convenient for arrangement in a box-type substation. Compared with the existing SF6 gas-filled cabinet, the size is consistent, which is convenient for transforming the original substation, and its use of environmentally friendly gas is greener.

[0049] In one embodiment, the transformer 3 is a dry-type transformer. Compared with an oil-immersed transformer, a dry-type transformer has the advantages of small size and no risk of oil leakage.

[0050] In one embodiment, the low-voltage complete cabinet 4 is a one-input four-output line 403 arrangement structure; the four-output line 403 is formed by two low-voltage output cabinets 402, and each low-voltage output cabinet 402 is arranged with one output line 403 in front and behind, and the front and rear output lines 403 share the middle top cross-connecting bus 404, wherein the output line 403 is generally formed by a knife switch and a plurality of molded case circuit breakers electrically connected. This arrangement realizes a compact design of the low-voltage complete cabinet 4, occupies less space, and is suitable for substation applications.

[0051] In one embodiment, the intelligent network camera 5 is capable of realizing fusion perception of temperature, humidity, video monitoring, infrared thermal imaging and smoke information.

[0052] The air conditioning device 6 is intelligently driven through the data acquisition and monitoring control system to start the high temperature, cooling or dehumidification function.

[0053] The data acquisition and monitoring control system is connected and controlled with customer terminals and mobile devices via 4G network communication.

[0054] In this embodiment, specifically: First, the intelligent network camera 5 is responsible for sensing the temperature, humidity, video monitoring, infrared thermal imaging and smoke information of the environment. It monitors the environmental parameters in real time through built-in sensors and corresponding algorithms, and transmits these data to the data acquisition and monitoring control system.

[0055] After receiving the data from the intelligent network camera, the data acquisition and monitoring control system processes and analyzes it, and sends instructions to control the air conditioning equipment according to the needs of the environment 6. According to the temperature conditions, the system can intelligently adjust the working mode of the air conditioning equipment, including starting the high temperature mode, cooling mode or dehumidification mode to meet the user's needs for air conditioning.

[0056] At the same time, the data acquisition and monitoring control system communicates with customer terminals and mobile devices through the 4G network. This means that users can remotely monitor and control the working status and parameter settings of air-conditioning equipment through mobile devices or customer terminals. Users can view the video monitoring screen provided by the camera in real time and obtain environmental information such as temperature and humidity. In addition, if an abnormal situation occurs, such as smoke information triggering, the system can send an alarm message to the user in time so that the user can take appropriate actions.

[0057] In short, the intelligent network camera senses environmental information, and the data acquisition and monitoring control system processes and analyzes this information, and communicates with the air-conditioning equipment and users in real time to achieve intelligent driving and remote monitoring and control of the air-conditioning equipment. Such a system can improve the accuracy and convenience of environmental monitoring and air-conditioning control, and provide users with a more intelligent, comfortable and safe living environment.
