摘要
作为主要的电能传输介质,电力电缆绝缘状态的好与坏直接关乎到电力传输是否安全,因此电力部门一直尤为重视电力电缆绝缘状态的监测工作。目前通常采用预防性试验与人工巡检两种途径来监测电力电缆的绝缘状态,但是这两种方法均存在一定弊端。文章设计研究了一种新的电缆接地环流在线监测技术,以妥善监测电力电缆的绝缘状态。
As the main energy transmission medium,the good or bad state of power cable insulation is directly related to whether the power transmission can be carried out safely. Therefore,the power sector has paid special attention to the monitoring of the insulation state of power cables. At present,two methods of preventive test and manual inspection are usually used to monitor the insulation state of power cables. However,both methods have some drawbacks. The paper designed a new technique of on-line monitoring of cable ground circulation. The insulation state of the power cable was more properly monitored.
