Current temperature on-line monitor and fault is the rin g net switch cabinet, cable branch box, box installed in the power distribution network system becomes, for a real-time online monitoring device indicates the corresponding section of the cable short c ircuit and ground fault current, temperature and time. When the line is in trouble, the staff c an quickly determine the fault section by the warning indication of the indicator, and find out the fa ult point. At the same time, real-time alarm information can be sent to the monitoring center server, a regional fault location and location for monitoring the computer screen, the guide line patrol offic ers to quickly determine the fault section and find the point of failure. In order to solve the p roblem of fault finding, it provides the best way to improve the work efficiency, shorten the outage tim e, quickly restore the power supply, and improve the reliability and economic efficiency of power su pply, which is of great significance.
