The invention relates to a comprehensive detection system and method for a cable-type fault indicator. The system includes a detection main control and a human-machine interface module, a transmitter, a receiver and a serial port detection module; the system accepts various external detection instructions and controls the transmitter. And the receiving end detection module collects the optical fiber signal waveforms sent by the optical fiber probe at the sending end and received at the receiving end through the IO interface; and transmits the collected signal waveforms to the system for analysis or direct output; the serial port detection module is electrically connected to the serial port through the serial port. On the serial port of the cable-type fault indicator, the detected serial communication data is transmitted to the main detection control module for analysis or directly output to the man-machine interface module. The comprehensive detection system and method designed by the invention can quickly locate the fault of the cable-type fault indicator system in the research and development and field test, and improve the fault location efficiency of the power grid and the detection equipment.
Description
technical field [0001] The invention relates to the field of power distribution monitoring. A comprehensive detection system and method for cable-type fault indicators are used to monitor the faults of cable-type fault indicator equipment, accurately record and locate, and assist in improving the communication stability of cable-type fault indicator equipment. . Background technique [0002] In the distribution network system, especially in the large-scale distribution network system, if a short-circuit fault or ground fault occurs in the distribution network system of the lower level, the power supply system of the upper level must be able to analyze and judge within the specified time , Cut off the fault line in time to prevent subsequent accidents. The cable-type fault indicator can clearly mark the location of the fault. The maintenance personnel can quickly find the faulty section according to the fault location information provided by the cable-type fault indicator, d...
