摘要
常规的架空线路非接触式检测节点一般采用固定检测形式,检测针对性不强,对于线路的检测精度并不高,导致带电检测相对误差降低,为此提出对配电网架空线路非接触式带电检测技术的分析和研究。依据实际的检测需求及标准,先进行非接触式红外检测数据预处理,以此为基础构建动态化的检测形式,设计多维层级检测节点,同时提升检测的精准度和针对性,实现动态检测节点的部署,根据检测目标的变化,构建非接触式红外识别带电检测模型,采用边缘分割扫描实现带电检测。最终的测试结果表明,对比于传统零值绝缘子红外检测小组、传统复合绝缘子憎水性的带电检测小组,所设计的非接触式红外识别带电检测小组最终得出的相对误差较低,均控制在1.5 kV以下,表明对于架空线路的带电检测精度更高、误差可控,具有实际的应用创新意义。
The conventional non-contact detection node of overhead lines generally adopts fixed detection,which is not targeted,and the detection accuracy of the lines is not high,leading to the reduction of the relative error of live detection.Therefore,the analysis and research on the non-contact live detection technology of overhead lines in distribution network is proposed.According to the actual detection requirements and standards,the non-contact infrared detection data shall be preprocessed first.Based on this,a dynamic detection form shall be constructed,and multidimensional hierarchical detection nodes shall be designed.At the same time,the detection accuracy and pertinence shall be improved to achieve the deployment of dynamic detection nodes.According to the change of detection targets,a non-contact infrared recognition live detection model shall be constructed,and the live detection shall be realized by edge segmentation scanning.The final test results show that:compared with the traditional zero value insulator infrared detection group and the traditional composite insulator hydrophobicity live detection group,the non-contact infrared identification live detection group designed in this paper finally obtains a relatively low relative error,which is controlled below 1.5 kV,indicating that the live detection accuracy for overhead lines is higher,the error is controllable,and has practical application innovation significance.
