Overhead distribution line fault mechanism is a complex and multi-dimensional concept, electrical fault mechanism including single-phase grounding, mixed lines, lightning strikes, external damage caused by two-phase short-circuit, as well as disconnection faults and insulation factors that cause insulation breakdown. Mechanical damage failure mechanism type can be more, like the previous ice, and strong winds lead to conductor wind bias, illegal construction work, house barriers, tree barriers and other external forces to bring external damage to the line failure potential.

Scientific and technological forces into the distribution network, one is the wide application of automation systems, from the automatic control of substations to feeder automation, from intelligent switchgear to the intelligent management of distributed energy, a series of automation technologies work in concert to realize the intelligent regulation and control of distribution network operation; the other is the intelligent monitoring equipment to enhance the degree of diagnosis of the faults, that is, the application of fault monitoring system for distribution lines.

Dingsin Wisdom TechnologyDistribution Line Fault Monitoring System AdoptionUsing solar energy plus coupling double power extraction, the working principle is mainly based on the use of traveling wave ranging technology, the monitoring end loaded onto the conductor, the collection of line condition monitoring, small current grounding line selection, hidden trouble early warning, fault location and other multi-functionality in one, direct acquisition of the primary side of the high-potential line waveforms, the pilot area of the overhead line fault diagnosis of distribution lines. The correct rate of fault diagnosis of overhead line distribution lines in the pilot area has reached.
