摘要
由于现行方法在配电网输电线路检修运维中应用效果不佳,不仅检测结果比实际一致性系数值低,而且运维期间配电网停电时间较长,无法达到预期的运维效果,为此提出了基于红外成像技术的配电网输电线路检修运维方法.利用红外扫描仪对输电线路扫描,生成输电线路热成像信息,通过对红外成像分割,提取图像前景,根据图像前景中线路温升、最大温差信息,确定输电线路最大相对温差,检测到输电线路运行故障,并对其进行相应的维修,以此完成基于红外成像技术的配电网输电线路检修运维.经实验证明,设计方法输电线路状态检测与实际一致性系数在0.9 以上,运维期间配电网停电时长在 5 min以内,设计方法在配电网输电线路检修运维方面具有良好的应用前景.
Abstract
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.
