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。
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.
