Comprehensive Safety Monitoring and Early Warning System for Power Cable Tunnels

1. Model: TLKS-PMG-CTM

Cable On-line Monitoring System

Today, we would like to introduce Telcom’s Cable On-line Monitoring System, which not only enhances the emergency response capability of power companies, but also provides strong guarantees for the safety and smooth operation of urban power supply. Through the implementation of this system, power companies can manage cable tunnels more efficiently, reduce the cost and labor intensity of manual maintenance, and improve maintenance quality. At the same time, this system can also help power companies better understand the operation status of cable tunnels, providing valuable data support for future power planning and development.

2. Working Principle

The cable tunnel on-line monitoring system accesses the IoT management platform through edge devices using Ethernet interface MQTT protocol to monitor and manage the entire tunnel. Combined with big data technology and intelligent network algorithms, it can analyze and utilize various data sources such as partial discharge, sheath, and temperature measurement, and apply high-tech means such as data trend analysis, artificial intelligence learning, and neural network diagnosis to diagnose and analyze the operation status of cables, and output cable status evaluation results, providing technical assistance and data support for power inspection work, and realizing comprehensive monitoring of high-end smart grids.

3. Functions of Each Subsystem

1. Cable Fault Location System: Conducts real-time monitoring and early warning of cable operation status, and quickly and accurately determines the location of fault points and the type of faults.

2. Distributed Optical Fiber Temperature Measurement System: Conducts real-time monitoring of the cable surface temperature, alarms in time when overheating faults are detected, and quickly and accurately determines the location of fault points.

3. Sheath Grounding Current Monitoring: Conducts real-time monitoring of cable sheath circulating current and grounding wire current, alarms in time when cable insulation defects are detected, and quickly and accurately determines the location of fault points.

4. Partial Discharge Monitoring System: Conducts real-time monitoring of cables, can timely detect partial discharge phenomena in cables, so that corresponding measures can be taken.

5. Tunnel Video Monitoring System: Installs cameras and uses information-based automatic monitoring technology to transform from traditional manual inspection to computerized automatic monitoring.

6. Water Level Monitoring and Drainage System: The on-line water level monitoring and automatic drainage system helps solve water accumulation problems and ensure the safety of power transmission and distribution systems.

7. Gas Monitoring and Ventilation System: When the concentration of toxic and harmful gases reaches a certain value, the system will alarm in time and automatically activate the ventilation system to protect the safety of staff. It can also effectively prevent fire accidents caused by excessive concentration of flammable gases.

8. Intelligent Manhole Cover Monitoring System: Can sense the status of manhole covers, such as opening, closing, moving, etc., and realize functions such as remote opening and closing.

9. External Damage Prevention Monitoring System: The external damage prevention monitoring system real-time measures the vibration around transmission lines, can effectively monitor mechanical construction activities and construction locations near cable tunnels, and send alarm information in time.

10. Settlement Monitoring System: The main purpose of settlement monitoring is to monitor and evaluate settlement changes in real time.

11. Fire Alarm and Automatic Fire Extinguishing System: When a fire occurs in a cable tunnel, the system will alarm in time and activate the automatic fire extinguishing system, which can effectively prevent the spread of the fire.

4. Conclusion

By establishing such a fully functional cable on-line monitoring system, the stability and reliability of the power system will be significantly improved. This not only helps ensure the safety and smooth operation of urban power supply, but also provides strong support for the operation and management of power companies. Therefore, Telcom’s Cable On-line Monitoring System is of great significance for the normal operation of cities and the development of the power industry.
