Distribution network overhead line insulation telemetering and fault distance detection device

The invention provides a distribution network overhead line insulation telemetering and fault distance detection device, which comprises a shell assembly, a panel assembly and a detection assembly, and is characterized in that the shell assembly is used for providing an accommodating space and outer side protection for the panel assembly and the detection assembly. The panel assembly comprises a plurality of detection interfaces and a display screen, and is used for connecting a detected cable and displaying result information. The detection assembly can detect insulation of a cable at a positioning fault point, can identify a low-resistance fault and a high-resistance fault, and carries out fault positioning, the detection assembly determines a fault type through real insulation data of a contact-type rapid measurement line, and the processing module processes the fault according to the line fault type. The pulse generator is controlled to send a detection signal to the detected cable, and after the signal c
