Automatic power distribution network fault positioning system

The utility model discloses an automatic power distribution network fault positioning system, which comprises at least one fault indicator (1), a data transfer station (2), a center station (3) and a monitoring main station (4), wherein the output of the fault indicator (1) is connected with the input of the data transfer station (2), the data transfer station (2) is connected with the center station (3) through a communication system, the center station (3) is connected with the monitoring main station (4) through a bus, and the fault indicator (1) comprises at least one fault probe (5), at least one data collector (6) and a variable load (7). The automatic power distribution network fault positioning system can fast detect a fault position, simultaneously, the action information of the fault indicator is collected to the monitoring center, afault point is calculated through the network topology, then, the concrete position of a fault is displayed on the image of the monitoring system according to the fault point, and in addition, the information is sent to relevant operation personnel in a short message mode.
