I. Requirements Analysis
Frequent distribution network failures can cause abnormal power outages for users, resulting in economic losses. Additionally, the unpredictability of line faults and inadequate real-time monitoring may lead to serious accidents such as pedestrian electrocution and forest fires. Addressing challenges such as unverifiable fault causes, inadequate real-time monitoring, and external hazards like construction sites near fish ponds or beneath operational lines, our proprietary Distribution Fault Visualization System provides real-time safety monitoring of line operations. It enables visual surveillance of potential hazards surrounding lines, ensuring reliable fault detection, elimination of latent risks, and prevention of unnecessary outages.
II. Working Principle
The Distribution Fault Visualization Device is suspended on power lines. When a fault occurs, it generates an instantaneous high-frequency disturbance at the fault point, accompanied by the formation of high-frequency traveling waves that propagate along the line in both directions. Since the propagation speed of these traveling waves is constant, measuring the time difference of wave arrival and combining it with the line's fundamental parameters enables the precise calculation of the fault location.
III. Features and Functions
1. Online Fault Location: 24/7 online monitoring, real-time acquisition of initial traveling wave current and fault power frequency current at the moment of fault occurrence, precise sampling of fault waveforms to assist in fault analysis.
2. Location time: 5 minutes. Significantly enhances cable fault location efficiency, minimizes user power outage duration, and generates economic and social benefits for customers.
3. Precise Location: <0.1% L + 5 meters. Utilizes BeiDou (GPS) high-precision timing and traveling wave velocity online calibration technology for more accurate fault location.
4. Positioning reliability rate: >95%;
5. Fault identification rate: >95%;
6. Live installation without power interruption;
7. Monitor and locate cables up to 5 km in length.
