The application of the warning network (safety monitoring and early warning network system) in the cable line is crucial, which can significantly improve the safety, stability and operation and maintenance efficiency of the power system. The following are its main application areas:

1. Cable temperature and overload monitoring

Application: Real-time monitoring of cable surface and joint temperature through optical fiber temperature measurement (DTS) or wireless temperature sensor, combined with the warning network analysis data, predicting overload risks.

Advantage: Prevent insulation aging, short circuit or fire caused by overheating.

2. Partial discharge detection

Application: Deploy high-frequency sensors or ultrasonic equipment to monitor partial discharge phenomena in cables, and the warning network identifies abnormal discharge signals in real time.

Advantage: Early detection of insulation defects to avoid sudden failures (such as breakdown).

3. External force damage warning (third-party construction)

Application: Install vibration sensors or distributed acoustic sensors (DAS) along the cable. When excavators, pile drivers, etc. approach, the warning network triggers sound and light alarms and links the law enforcement system.

Advantage: Reduce power outages caused by digging cables during construction (especially for underground cables).

4. Cable theft protection

Application: Using current monitoring + video analysis, when abnormal current interruption or manual wire cutting is detected, the warning network links the security system and notifies law enforcement personnel.

Advantages: Curbing metal theft and reducing economic losses.

5. Environmental disaster warning

Application:Flood/water accumulation monitoring: Installing water level sensors in high-risk areas of flooding to trigger cable power-off protection.

Landslide monitoring: Early warning of cable tower base displacement through inclination sensors or geological radar.

Advantages: Reduce damage to power facilities caused by natural disasters.

6. Insulation aging and life prediction

Application: Integrating dielectric loss sensors or time domain reflectometers (TDR), the warning network analyzes the degradation trend of cable insulation performance.

Advantages: Realize preventive replacement and avoid unplanned power outages.

7. Intelligent inspection and drone collaboration

Application: The warning network combines drone infrared thermal imaging or laser radar (LiDAR) to automatically identify hidden dangers such as exposed cables and tree barriers.

Advantages: Replace high-risk manual inspections and improve efficiency.

8. Fault location and rapid recovery

Application: Using traveling wave fault location technology, the warning network locates the fault point in seconds after a short circuit or disconnection, and guides emergency repairs.

Advantages: Shorten power outage time and improve power supply reliability.

9. Electromagnetic interference and harmonic monitoring

Application: Monitor the electromagnetic environment around the cable, and warn of excessive harmonics or illegal power theft.

Advantages: Ensure the quality of power grid power and reduce equipment damage.

10. Public safety warning

Application: Deploy electronic fences or warning signs near high-voltage cables, and remotely control flashing reminders through the warning network.

Advantages: Prevent people from electric shock or entering dangerous areas by mistake.
