摘要：针对传统架空线路缺陷检测方法存在的不足，本文提出了一种基于第二代小波变换技术和双向脉冲交互的架空线路缺陷检测及定位方法，通过第二代小波变换技术克服了原有噪声信号对信号处理及分析的干扰，大幅度提高了检测效率。双向脉冲交互技术通过双边信号中脉冲的极性，可以准确定位缺陷发生的位置，大大提高了缺陷定位的精度。本方法原理简单，实施方便，具有较高的推广前景，为进一步提高供电可靠性、提升人民群众用电“获得感”“幸福感”提供了坚强保障。
Abstract: In response to the shortcomings of traditional overhead line defect detection methods, this paper proposes a defect detection and localization method for overhead lines based on second-generation wavelet transform technology and bidirectional pulse interaction. Through the second-generation wavelet transform technology, the interference of original noise signals on signal processing and analysis is overcome, greatly improving the detection efficiency. The bidirectional pulse interaction technology can accurately locate the location of defects by using the polarity of the pulses in the bilateral signals, greatly improving the accuracy of defect localization. This method has a
simple principle, easy implementation, and high promotion prospects, providing a strong guarantee for further improving power supply reliability and enhancing the people's sense of "gain" and "happiness" in electricity use.
