Application |
The current temperature and fault online monitoring device is a real-time online monitoring device installed on the ring network switchgear, cable branch box, and box transformer in the distribution network system, used to indicate short circuits and grounding faults in corresponding cable sections, as well as real-time current and temperature. When a fault occurs in the line, the staff can use the alarm indication of the indicator to quickly determine the faulty section and locate the fault point. At the same time, the alarm information can be sent in real time to the server in the monitoring center, and the area and specific location of the fault can be displayed on the screen of the monitoring computer, guiding the line patrol personnel to quickly determine the fault section and find the fault point. Providing the best way to solve the problem of fault finding is of great significance for improving work efficiency, shortening power outage time, quickly restoring power supply, enhancing power supply reliability and economic benefits.
