A Method for Maintenance and Repair of Transmission Lines in Distribution Networks Based on Infrared Imaging Technology
Current methods perform disappointingly in maintenance and repair of distribution network transmission lines,as the consistency coefficient between detection results and actual value is relatively low,and power outage time of the dis-tribution network is relatively long during the operation and maintenance period,which cannot achieve expected operation and maintenance effect.Therefore,a distribution network transmission line maintenance and repair method based on infra-red imaging technology is proposed.Using an infrared scanner to scan transmission lines and generate thermal imaging in-formation,the infrared imaging is segmented to extract the image foreground.Based on temperature rise and maximum temperature difference information of the line in the image foreground,the maximum relative temperature difference of the transmission line is determined,and transmission line operation faults are detected and repaired accordingly.This com-pletes the maintenance and operation of distribution network transmission lines based on infrared imaging technology.It has been proven by experiments that the consistency coefficient between the designed method and actual transmission line status detection is above 0.9,and the power outage duration of the distribution network during operation and maintenance is within 5 minutes.The designed method has good application prospects in maintenance and repair of distribution network transmission lines.
