摘要

文中提出"非谐振"叠加的方法

实现了电力电缆的在线监测。该方法通过在电缆的绝缘层上叠加1个101H z的交流信号

再检测电缆绝缘屏蔽层上1H z的特征信号。现场应用表明

系统分析诊断正确

运行稳定可靠。

Abstract

A non-resonant superposition method was presented to realize power cable on-line monitoring.A 101Hz AC signal was added on the insulator layer of cables and a 1Hz characteristic signal on insulator shielding layer was detected.Practical application indicated that monitoring system was stable and diagnosed correctly.
