Problems solved by technology

Although the traditional fault indicator can indicate the fault current flowing through the line through the optical plate, it still needs to inspect the line to find the fault section, and the workload of the line inspection is still very large, which affects the stable operation of the line

Abstract

Disclosed in the invention is a fault monitoring system for a power transmission line. The fault monitoring system comprises a transmission line signal collecting device and a monitoring center. The transmission line signal collecting device consists of a temperature sensor, a hall sensor, a fault indicator light, a microcontroller, a GPS positioning module, and a data transmission module; the microcontroller receives fault signals sent by the temperature sensor and the hall sensor; a line fault position is obtained by the GPS positioning module; and the data transmission module sends the fault signals and the line fault position to the monitoring center. After a fault occurs within a few minutes, a fault position can be provided and then the fault point information is sent to the monitoring center, so that the maintenance staff can go to the field rapidly and thus a potential failure can be eliminated. Therefore, reliable and effective data can be provided for the operation staff and the maintenance staff to carry out operation and maintenance, fault analyses, and line repairing, thereby substantially improving the operation reliability of the power transmission line.

Description

technical field [0001] The invention relates to the field of power transmission lines, in particular to a power transmission line fault monitoring system. Background technique [0002] In recent years, with the rapid development of economy, the power industry is facing more and more pressure. The continuous increase of power supply load requires more reliability of power supply. However, in the power transmission operation system, there are many branches of the line, the operation mode is complicated, the distance of the overhead transmission line is long, the distribution is wide, the terrain is complex, and the line inspection is difficult. Phase-to-phase short-circuits or single-phase ground faults often occur in transmission lines under harsh weather and environmental conditions, and the instantaneous faults exceed 80%. The local insulation damage caused by such faults generally has no obvious traces, which brings great difficulties to the search. [0003] How to quick...
