摘要
采用高频宽带电磁耦合法检测了XLPE绝缘电力电缆的局部放电信号 ,用基于分形学分数维数和自相似原理识别、处理局部放电信号的数字分析系统来有效提取局部放电信号特征值 ,抑制或剔除噪声信号干扰。还提出了XLPE绝缘电力电缆局部放电在线监测、巡测的基本方法。
Based on variety of fractal dimension scale and principle of self-similarity, this paper presents a new digital analysis system for PD signal recognizing and processing. Application of fractal character to calculate and detect PD pulse signal of XLPE power cable using high frequency wide-band electromagnetic coupling is able to restrain noise interference and pick up PD signal key eigenvalue effectively. The technique for on-line detection of partial discharge in XLPE power cable has been improved in this paper.
