摘要
为实现对配电线路异常发热现象的感知,提升故障诊断与定位结果的准确性,文章提出基于红外测温技术的配电线路状态检修方法.设置红外热成像仪,采集配电线路红外热成像图像;对图像进行灰度化处理,采用线性平滑滤波技术,进行图像的空间域滤波处理,完成红外图像的去噪;引进模板匹配技术,选择一个代表区域作为模板,在图像中寻找与已知模板最相似区域,进行配电线路故障诊断和定位.实验证明,设计的方法在实际应用中,不仅可以实现对线路运行中过热温度的准确测量,而且能精准定位配电线路故障点.
Abstract
To achieve the perception of abnormal heating phenomena in distribution lines and improve the accuracy of fault diagnosis and localization results,this article proposes a state maintenance method for distribution lines based on infrared temperature measurement technology.Set up an infrared thermal imaging device to capture infrared thermal imaging images of power distribution lines.Perform grayscale processing on the image,use linear smoothing filtering technology to perform spatial domain filtering on the image,and complete denoising of the infrared image.Introducing template matching technology,selecting a representative area as the template,and searching for the most similar area in the image to the known template for distribution line fault diagnosis and localization.Experimental results have shown that the designed method can not only accurately measure the overheating temperature during line operation,but also accurately locate the location of distribution line faults in practical applications.
