摘要
在分析 110 / 2 2 0kVXLPE电缆绝缘在线监测的适用方法的基础上 ,提出了一种以监测低频响应信号和直流成分的复合在线监测法。考虑设备保护和排除干扰等因素 ,指明了该监测系统的各部分具体实现途径。
In this paper, the feasible methods of on line monitoring of 110/220 kV XLPE power cable insulation are analyzed. On the base of these methods, a compound on line monitoring method of low frequency response signal and direct current component is presented. Considering the factors of equipment protection and exclusion of disturbance, the details of realization of monitoring system are pointed out.
