1) By installing the urban ring network power supply cable fault warning and line selection and positioning system, automation is achieved in terms of fault line selection, fault early warning, and automatic ranging, which greatly improves the efficiency of troubleshooting, saves a lot of time and manpower, and greatly improves work efficiency. 2) The automation level of the distribution network has been improved, and measures can be taken in advance in a planned manner to ensure the safe operation of equipment in the plant area, ensure the reliable power supply of the power grid, and avoid unnecessary economic losses caused by sudden power outages. 3) The system software platform is deployed on the cloud server side, which is convenient for operators to access, not limited by time and place, and can view the line operation in real time, which is convenient for management.
4) The system device has a compact structure and is convenient for construction and installation. It can conduct long-term monitoring of key stations, key equipment and abnormal equipment, and the system configuration is flexible. 5) The installation of the system does not change the operation mode and structure of the cable, and does not occupy the existing system resources. It is safe and reliable to install the current sensor on the cable grounding conductor, which can monitor long cables. The maximum length of the monitoring cable is 40km. 6) The system devices are fully networked, with various communication methods: each device can be assigned a different IP address through 4G wireless communication, network communication, and optical fiber communication, and can simultaneously conduct real-time online monitoring and fault warning for multiple circuits.
7) The system response time is short. When a transient fault occurs in the cable to generate a discharge signal, the high-frequency sensor can transmit the collected fault signal to the host computer software through network communication within 5s and display the fault waveform in real time, which is convenient for the on-duty personnel. Quickly analyze the point of failure. 8) Real-time monitoring of the grounding current of the sheath of the single-core cable in the urban ring network, to realize the abnormal alarm of the grounding current of the cable sheath. The installation diagram of the ring network cable monitoring system The system monitoring host is responsible for accessing the system server, the system server adopts the cloud server, and the system user accesses the system background through the browser.
