Overhead Distribution Line Fault Monitoring System

Abstract

The invention discloses a fault monitoring system for overhead power distribution lines, which comprises a main station, one or more sub-stations connected to the main station, and each sub-station is connected with three fault detectors, and the three fault detectors are respectively connected to three In the phase circuit; the fault detector judges whether the measured line is initially faulty according to the detection signal; the substation synthesizes the preliminary fault information of the three-phase fault detector to determine the final fault information; the master station stores the topology structure of the entire overhead distribution line , display the final fault and fault type, and give an alarm. The invention has the characteristics of strong real-time performance, resource saving and the like, and can be widely used in power distribution lines.

Description

technical field [0001] The invention relates to a detection technology, in particular to a fault monitoring system for overhead power distribution lines. Background technique [0002] The overhead distribution lines connecting substations and various power consumption places are generally distributed in a tree shape, including trunk lines, branch lines and sub-branch lines, until finally delivered to the distribution transformer. Currently, when overhead distribution lines fail, technicians are required to manually detect them. [0003] It can be seen that, in the prior art, the fault detection of overhead distribution lines has poor real-time performance; moreover, due to the widespread distribution of overhead distribution lines, the fault detection of overhead distribution lines will waste a lot of human resources. Contents of the invention [0004] The technical problem to be solved by the invention is to provide a fault monitoring system for overhead power distributi...
