[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0021] Example 1:

[0022] refer to Figure 1 The holographic sensing ring main unit includes a cable compartment 10, a pressure relief compartment 11, a mechanism compartment 12, an air box 13, and a control box 14 installed inside the cabinet. The cable compartment 10 and the pressure relief compartment 11 are located at the bottom of the cabinet, the air box 13 is above the pressure relief compartment 11, the mechanism compartment 12 is next to the air box 13, and the control box 14 is above the mechanism compartment 12.

[0023] In the above scheme, the cable compartment 10 is mainly used for cable introduction and exit, and is an important part of the ring main unit's connection with external cables. It is equipped with cable clamping devices and cable seals to ensure a stable connection and good sealing of the cables. Through the cable compartment 10, the ring main unit can be connected to cable branch boxes or other electrical equipment to realize power transmission and distribution. When a fault occurs inside the ring main unit, such as a short circuit or arc discharge, high-temperature and high-pressure gases may be generated. The pressure relief compartment 11 (or explosion-proof device) ensures that these gases are released in a timely manner, preventing equipment damage and personnel injury. The mechanism compartment 12 is the installation location for various operating mechanisms in the ring main unit, including the operating mechanisms of circuit breakers, grounding switches, and disconnect switches. These mechanisms are equipped with manual or electric energy storage spring operating mechanisms to achieve rapid opening and closing operations of the switches. The mechanism compartment 12 controls and operates the internal electrical components of the ring main unit through the operating mechanisms. The gas box 13 improves the insulation performance and arc extinguishing capability of the ring main unit by encapsulating insulating media.

[0024] refer to Figure 1 and Figure 2 The mechanism chamber 12 is equipped with three current sensors 18, which are respectively installed on the closing coil, the opening coil, and the energy storage motor circuit. An angle displacement sensor 16 is installed on the output shaft of the energy storage motor. The control box 14 is equipped with a local display 15 and a smart gateway 24. The electrical signals of the current sensors 18 and the angle displacement sensor 16 are input to the local display 15. The local display 15 and the smart gateway 24 are connected by an RS485 interface.

[0025] In the above solution, the local display 15 is connected to the smart gateway 24 via an RS485 interface, enabling remote data transmission and management, improving data accessibility, and allowing users to monitor and manage remotely, thereby improving work efficiency and flexibility. In summary, by integrating components such as the angle displacement sensor 16, the current sensor 18, the local display 15, and the smart gateway 24, the system achieves real-time monitoring, remote management, and fault early warning functions for the energy storage motor, providing users with a more efficient, safe, and reliable motor operation solution. Furthermore, the angle displacement sensor 16 is non-contact, and the current sensor 18 is non-invasive.

[0026] Further reference Figure 1 and Figure 2 The room 12 is also equipped with a night vision camera 22, and the electrical signal of the night vision camera 22 is connected to the local display 15.

[0027] In this further implementation, the night vision camera 22 allows maintenance personnel to remotely monitor the interior of the facility 12 without having to enter the site in person. This reduces the risk of personnel entering dangerous areas and improves overall security. At the same time, the night vision camera 22 can also serve as an evidence collection tool, providing strong video evidence in the event of a security incident.

[0028] Further reference Figure 1 and Figure 2 The mechanism room 12 is also equipped with a density relay 17, and the air box 13 is equipped with a pressure gauge 25. The pressure gauge 25 inputs an electrical signal to the density relay 17, and the density relay 17 feeds back the signal to the local display 15.

[0029] In this further embodiment, the pressure gauge 25 can monitor the gas density changes inside the gas tank 13 in real time, ensuring that the gas medium (such as dry air or N2) is maintained within the set safe range. With the intervention of the density relay 17, when the pressure gauge 25 detects that the gas density is lower or higher than a preset threshold, it will automatically trigger an alarm signal and issue a warning to maintenance personnel via the local display 15. This helps to promptly detect and handle abnormal gas density, preventing equipment failure or safety accidents. The local display 15 can intuitively display real-time gas density data and alarm information, enabling maintenance personnel to quickly understand the status of the gas tank 13.

[0030] Further reference Figure 1 and Figure 2 The cable compartment 10 is equipped with a partial discharge sensor 19 and a temperature sensor 20, with the temperature sensor 20 located inside the cable joint.

[0031] In this further embodiment, the partial discharge sensor 19 can monitor partial discharge phenomena in the cable compartment 10 in real time. By monitoring partial discharge, potential defects or damage in the cable insulation layer can be detected in a timely manner, thereby preventing cable faults caused by partial discharge. The temperature sensor 20 can monitor the operating temperature of the cable in real time; it can detect overheating or abnormal temperature rise of the cable in a timely manner, thereby preventing cable faults caused by excessive temperature. The partial discharge sensor 19 and the temperature sensor 20 transmit wireless signals to the partial discharge monitoring host and the temperature receiving host, which then transmit the recorded data to the local display 15. The real-time monitoring data of the partial discharge sensor 19 and the temperature sensor 20 can be viewed on the local display 15.

[0032] Further reference Figure 1 and Figure 2 The cable compartment 10 is also equipped with a temperature and humidity sensor 21 and an intelligent dehumidification device 23. The electrical signal of the temperature and humidity sensor 21 is input to the intelligent dehumidification device 23, and the signal of the intelligent dehumidification device 23 is connected to the local display 15.

[0033] In this further embodiment, the temperature and humidity sensor 21 can monitor the temperature and humidity changes inside the cable compartment 10 in real time, providing accurate environmental data for maintenance personnel. The intelligent dehumidifier 23 automatically adjusts its dehumidification operation based on the data provided by the temperature and humidity sensor 21, ensuring that the humidity inside the cable compartment 10 is maintained within a suitable range. This helps prevent cables from becoming damp, moldy, or experiencing insulation degradation due to excessive humidity, thereby extending the cable's service life. The signal from the intelligent dehumidifier 23 is connected to the local display 15, allowing maintenance personnel to monitor the dehumidifier's operating status and the temperature and humidity conditions inside the cable compartment 10 in real time, improving the efficiency and accuracy of maintenance management. The temperature and humidity sensor 21 is introduced into the intelligent dehumidifier 23 via a dedicated signal line to ensure accurate signal transmission.

[0034] Example 2:

[0035] refer to Figure 2 The intelligent gateway 24 accesses the cloud platform via a 4G network and the station control layer control center via an Ethernet network.

[0036] In the above scheme, the database of the station control layer control center is installed on the local computer for third-party platforms to call and integrate. The cloud platform includes web, mini-program, and collection APP terminal.

[0037] Sensors within the cabinet collect various data and transmit this data to a local display 15, which then transmits the data to the cloud platform and the station control center. The cloud platform stores the data and uses edge computing algorithms and big data analytics to determine the operating status and "health" of the ring main unit. This holographic sensing ring main unit utilizes power IoT technology, combined with online and offline services, to realize the smart power consumption concept of "unmanned operation and manned operation" in the power distribution system. Users can obtain real-time information about the equipment's health status through a mobile app or web interface, while the data center provides 24 / 7 comprehensive monitoring.
