摘要
高频诊断技术是检测高压交联电缆局部放电的重要方法之一。通过分析高频诊断技术的基本原理,可知传统的高频诊断技术存在无法准确区分局部放电的类型且抗噪声能力较弱的缺陷。笔者在此基础上提出基于模糊聚类分析的局部放电脉冲分离技术。同时从理论分析、实验室验证及现场测试几个方面进行讨论,并通过对测试数据的分析验证了该方法的有效性。
High frequency diagnostic technology is an important method for detecting partial discharge of high voltage XLPE cables. However, the traditional high-frequency diagnostic technology cannot accurately separate different types of partial discharge, and its ability of anti-noise is relatively weak. In this paper, a separation technique of partial discharge pulse is proposed based on fuzzy clustering for XLPE cables. The technique is discussed in terms of theoretical analysis, experimental verification and practical measurement. The validity of the technique is verified by the measured data.
