Distribution line fault detection and analysis positioning system

Abstract

The invention discloses a distribution line fault detection and analysis positioning system. The system comprises a cloud service platform, a data acquisition module, a data analysis module, a characteristic parameter integration module, an intelligent terminal, a fault analysis positioning module, a warning module and a database. According to the invention, pollution flashover, closing, single-phase grounding, short circuit, lightning stroke and other abnormal conditions of a power distribution line insulator can be detected, and the data analysis module and the characteristic parameter integration module are utilized to carry out single-item and integrated analysis on collected data, so that the power distribution line fault analysis result is more accurate, and people can be timely reminded to maintain the power distribution line.

Description

technical field [0001] The invention relates to the technical field of distribution line fault analysis, and more specifically, the invention relates to a distribution line fault detection, analysis and positioning system. Background technique [0002] With the development of my country's economy and the improvement of people's living standards, people have put forward more and higher requirements for the reliability of power supply. Power outages are the main reason affecting the reliability of power supply. According to statistics, power outages due to faults in the power system account for about 80% of the entire power outage time. Among these power outages, power outages due to line faults account for about 60%. . [0003] When dealing with these line accidents, the time to find faults accounts for 70-90% of the entire fault processing time. Among them, for high-voltage backbone transmission lines, because the line conditions are relatively simple and there are special ...

Problems solved by technology

[0003] When dealing with these line accidents, the time to find faults accounts for 70-90% of the entire fault processing time. Among them, for high-voltage backbone transmission lines, because the line conditions are relatively simple and there are special equipment for line fault detection, therefore, The fault finding and handling process is relatively convenient; however, for distribution lines with a mesh structure, there are many branches and the line conditions are complicated, so the fault finding and handling process is relatively difficult

[0004] Most of the existing fault detection devices are single detection. For example, the Chinese patent with the announcement number CN210690722U and the announcement date is 2020.6.5: a fault location system for power distribution circuit equipment. The patent only judges the fault by detecting the current and voltage. The detection parameters only for distribution lines are too single, the detection effect on distribution lines is insufficient, and there are certain potential safety hazards
